Nuvi 200/250 Service Firmware Printed from: GpsPasSion Forums Topic URL: http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=95274 Printed on: 27 Apr 2015 Topic: Topic author: neadrenalin Subject: Nuvi 200/250 Service Firmware Posted on: 16 Aug 2007 13:35:18 Message: nuvi has service mode (called PRE BOOT MODE) in which unit stays operable for some functions, such as firmware recovery.To access this mode hold POWER and do not release it.g7towin can access unit this mode and read/write some data (almanach, time, versions...)Mapsource CAN NOT write maps in this mode, cause of nuvi limited capabilities. The main way to access maps - use USB Mass Storage Device Mode.You can not revert firmware to older version using gupdate.gcd method.Both files for service firmware 2.60 have right CRC and available to download.Latest cure+original versions for different HWID:ID 0660http://e-trex.info/fw/nuvi/2xx/fw_nuvi2xx_v410_ID0660_all_en_cure_no_gpx_no_maps_no_bootloader_gupdate.rarID 0834http://e-trex.info/fw/nuvi/2xx/fw_nuvi2xx_v410_ID0834_all_en_cure_no_gpx_no_maps_no_bootloader_gupdate.rarID 0760 (TAIWAN Version!!!)http://e-trex.info/fw/nuvi/2xx/fw_nuvi2xx_ID0760_tw_v410.rarHOW TO know what HWID you have in your nuvi:1. disconnect usb2. shift-and-hold power button3. attach usb4. let windows to detect and install your device5. run g7towin6. select menu gps-get gps id7. find appropriate ID in the list Replies: Reply author: neadrenalin Replied on: 16 Aug 2007 13:50:08 Message: Problems, that service firmware can solve:1. After I put the world map as gmapsupp under /Garmin folder, the nuvi stocked on loading maps bar. Is there anybody now how to recover it? Now I even can not enter the USB storage mode.Answer: You have to start your device to have disks. OK.The main idea - to start the device and delete these gmapsupp.img wrong file. (or another "bad map" file img). How to do it if the unit does not start?Let's use the updater, PRE-BOOT mode and some modified self-made service firmware.http://e-trex.info/fw/nuvi/2xx/fw_nuvi2xx_en_v260_recovery_no_maps_visible.rarUnpack this file and start the device in the pre-boot mode. (hold the POWER button until the LOADER message appears) Pay attention that PRE-BOOT mode string is not displayed by 2xx nuvi, but other version such as 3xx and 6xx display it.Attach the device usb.Run updater and select nuvi.Click ok and proceed. Agree with updater if any additional messages appeared.If LOADER appeared on the screen you may release POWER button and wait until unit flashed.After success flashing unit restarts. (if you used WebUpdater before - gupdate.gcd needs to be deleted too! because of unit automatic firmware update after boot if this file exists, now it is no need in it, we will made it manually)Now unit should boot! And there is only basemap shown (no gmapsupp, no gmapprom, gmapprom1 visible).And now you can attach it as a Mass Storage Device and DELETE wrong gmapsupp (or whatever you need).Then you need to make flash for usual firmware for unit. I prefer usual firmware loaded in PRE-BOOT mode, I hate gupdate.gcd :)So, download the filehttp://e-trex.info/fw/nuvi/2xx/fw_nuvi2xx_en_v260.rarand use it as I described above.Now your nuvi is fully operational and have no "bad maps".2geeks. I made the service firmware manually and tested it successfuly today on my nuvi200. It works.2gpspassion. You may stick this question too and files. Be free to copy this content to another forums, it really can help people.The main idea to create restoring file is to rename texts like "gmapsupp" to something strange "umapsupp" in the firmware code. So, unit starts, searches umapsupp.img and does not find it - we are lucky, we need it :) Reply author: neadrenalin Replied on: 16 Aug 2007 13:56:09 Message: 2. After days passed my unit writed : SOFTWARE MISSING. How to recover it?Answer: Use recovery method from the 1 question and the http://e-trex.info/fw/nuvi/2xx/fw_nuvi2xx_en_v260.rar file.It recovers your unit and gives access to disks. So, you can use WebUpdater or another manual method to upgrade software version then.3. How can I revert to an older version of the firmware?Answer: Use http://e-trex.info/fw/nuvi/2xx/fw_nuvi2xx_en_v260.rar file and then upgrade to the necessary version. It does not revert GPS Chipset Version, XLOADER version, BootBlock version. If your unit had older version XLOADER than 0.68 it will be upgraded to 0.68, and if BootBlock had older version than 2.90 it will be upgraded too. I can make original versions for then (such as appeared in original 2.60 unit), but I have no time for it, sorry.Warninig! All your user data will be lost. Maps, files and unlocks should remain unchanged. Reply author: illiac4 Replied on: 20 Sep 2007 09:54:57 Message: Sorry but in .rar files there are only .rgn files. Where should i copy them to restore, from 3.30 to 2.60. And how long should i hold power button pressed on nuvi200? When i hold them pressed for some time the calibration screen comes out (Another hidden feature ;) )Cheers Reply author: neadrenalin Replied on: 22 Sep 2007 05:47:30 Message: You must know that .rgn files are used by updater.exe flashing ptogram (which is included in any firmware except nuvi series). Download from garmin for example 60csx firmware, unpack this self extracting archive to the selected place and find there updater.exe. updater and your nuvi .rgn file must be in the same directory.You have to pass all described steps when start flashing firmware no more than 30 seconds - calibration starts then. You have to release power button after seeing LOADER on the device's screen. Reply author: illiac4 Replied on: 22 Sep 2007 07:52:35 Message: TNX for help. I did that yesterday and now the Garmin is working without those bugs presented in 2.9, 3, 3.1, 3.3 firmware. It is really a shame of Garmin to ignore such bugs which causes the units to shut down and behave as they were broken. I hope Garmin will react and repair those bugs in the future release.TNX againCheers Reply author: marz505 Replied on: 23 Sep 2007 03:54:38 Message: Hi, I cannot enter service mode in my Nuvi 250. How is this achieved please? I tried keeping power slider to the left (power on) for nearly a minute, but the nuvi enters in TouchScreen callibration mode, not service mode. I tried several combinations but I never managed to enter into the Pre Boot mode to delete some corrupted files. Note that USB connection is not availableeither.

I have written a detailed and easy post (some 15 steps, 25mins of typing) how the pre boot loader works for newbies (we are not born expert aren't we), and that got also removed by the admin ??? Additionally I followed the instructions written here, and did not succeeded (there are some 2 or 3 such posts too, and open) so I do not really see the point of locking that topic. Kindly I ask the admin to reopen that topic for follow up. IMO it is unfair. I believe that the aim of this forum is to share knowledge and help each other, and their should be some degree of tolerance to everyone.

Bootloader starts first and it searches for gupdate.gcd file, then flashes it and starts again with your NEW old native firmware. I need more time to handle bootloader. It's VERY dangerous. :( Reply author: marz505 Replied on: 25 Sep 2007 08:15:03 Message: I will follow this post, then tell me how to pay you a small donation or at least send you a gift or some postcards. I can start by giving you a free membership to one of my pay websites: www.diskimaltin.com, which consist of traditional maltese Songs.To help you up in the research:All this started because the nuvi lost all the user data files (as if there was a factory reset) and so I tried to recover the files from the pc and place them back.I did 2 things which might made the nuvi wrong, but 99% it is the copying of the 'recovered' current.gpx thing over the new one. The other one was that I saved the recovered screen snapshot files back into the 'scrn' folder of Nuvi(if i remember well the dir name), but as I imagine, this has little effect on the operating system.I also have an additional data SD card with maps for Malta, but I tried the reflush with and without card.THANK YOU very much for your patience.

YEs, I did reflash correctly:I wrote a step by step of what happened during the reflash, but this post got deleted. briefly:1) The PC prog downloaded the file to garmin in two steps, stating updating software 2.90 (not 2.60?). Update sucessful, USB always connnected.2) Nuvi resetted and there was a splash screen with long welcome text at the bottom (4 lines). There was loader, Loader loading, Loader, Software loading... messages on nuvi.3) Nuvi resetted again, and there was the splash screen with a smaller welcome text (2 lines) at the bottom and back to the map loading freeze problem.I understood that 'cure' firmware does not help you in bad GPX file case.

Ask me for any details you need.[/quote] Reply author: neadrenalin Replied on: 25 Sep 2007 22:11:12 Message: as for (1) : 2.90 is bootblock, which starts when you put nuvi in pre-boot mode. 2.90 is because of flashed from gupdate.gcd file which is situated on garmin disk inside the device.When you make (2) 2.60 firmware and 2.70 bootloader flashed, then restarts, and bootblock SEARCHES for guodate.gcd. THEN it writes LOADER (now it is the way to change our 2,70 to 2,90), and finally SOFTWARE LOADING is broken our tries to success. Then 2.90 loads, and of course hangs.Solution. I need to create 3.30 cure firmware, so 3.30 bootblock will not proceed to flash "old" 2.90. And 3.30 cure will start. Is it clear? I will return soon, wait :) Reply author: marz505 Replied on: 26 Sep 2007 08:13:32 Message: THANK YOU, I'll wait for my saviour!So, if one would have deleted the .gcd file from garmin after a succesful upgrade, would it be a good idea, so as to avoid such situations, or the .gcd file has to STAY on nuvi ??? Reply author: popej Replied on: 26 Sep 2007 08:47:16 Message: You can remove .gcd after upgrade. And I can't see any reason to leave it on nuvi. It takes space and maybe even slow down nuvi start. Reply author: neadrenalin Replied on: 26 Sep 2007 08:48:03 Message: I prefer to have service firmware that CAN repair unit, rather gupdate.gcd that can not repair anything. So, after each update I'd recommend to delete this file. Nothing enormous will not happen - this is usual file, not actual working firmware code (until it's flashed), so it is safe to delete.

Be ready to say bye to your device. Then, everything should go right. I will cross my fingers to you.You should delete after device restarts in mass storage mode:a) gupdate.gcdb) maps (*.img)c) current.gpx and others GPX files that can bother you too.Then restart device.After that you must flash normal:http://e-trex.info/fw/nuvi/2xx/fw_nuvi2xx_v310_en.rar Reply author: marz505 Replied on: 27 Sep 2007 00:05:29 Message: Here is a step by step of the events:1) Flushed the first file with name xxx_cure_xxx.rgn2) V2.90 software uplaoding...3) When Nuvi booted, there was a big screen saying that no detailed maps are found, and the device cannot operate without them. At the back there was the PIN ID Keypad, I tried to input the keys, but nothing happened. 4) At this mode the USB mass storage did not come up on the PC. I could not delete or browse the garmin MSD.5) I went to preboot mode again, and updated the 2nd file6) Now a big screen came and said do you want to upgrade to an older verson?7) When I said Yes, it started the loader and software procedure8) When I said no (after repeating the whole thing) it just did nothingand so in any case the nuvi is back stuck on loading Maps...Dont panic, think a bit more the following morning whe you mind is fresh.

B I N G O ! ! !Popej, you gave me a hard time because you spelled the filename wrong, but finally I figured it out (its gmapsupp.img). Now I have an identified Garmin USB Mass Storage.I will first remove the current.gpx and replace it with that in the backup. Reply author: popej Replied on: 27 Sep 2007 09:22:05 Message: I hope my spelling is right for "cure" version of firmware. You don't have to replace current.gpx, simply delete it and nuvi will create new empty file. Reply author: marz505 Replied on: 27 Sep 2007 09:24:47 Message: Is there a prog or way to load the *.gpx file from the PC and download the waypoints to the Nuvi, instead of messing with moving of files from PC to the Mass Storage device? (So as I do not repeat the same mistake?)In the meantime, I am copying the mapfiles to my cured(?) nuvi250. Is it normal to take 72mins to copy the 1.3Gb mapfile (.img) from PC to Nuvi?!? Reply author: popej Replied on: 27 Sep 2007 10:17:25 Message: Change name of .gpx file into something else then current.gpx, for example to my.gpx and put this file into \Garmin\gpx\ directory. Nuvi after restart will add content of new file into current.gps.Alternatively you can read .gpx file with Mapsource and send waypoints to nuvi.Internal nuvi flash memory is really slow ;-) Reply author: marz505 Replied on: 27 Sep 2007 11:05:45 Message: SUCCESS !! HOORAY !! YUPEEE !!Okay, now I nearly have the full picture of the problem.I lost the user data files on my nuvi250 (dont know how it happened) and tried to restore deleted files with a prog on pc. The recovered current.gpx was placed over the good one, thinking that it will do the trick, but I made the unforgivable mistake not to check if the recoverd file is corrupted or not!Actually it was corrupted, and the nuvi250 went to Intensive Cure Unit. No maps loading, no USB connection, no cure after system firmware updates.The assumingly recoverd current.gpx file did not load on mapsource (set filetype as *.gpx else they do not show up), stating it is not reckognized. This is a good way to check the gpx files or uplaod to nuvi as popej said.Hence before putting files on the nuvi memory, check they are not corrupted and they are compatible, namely by loading them via mapsource.

Reply author: mm23500 Replied on: 20 Dec 2007 08:18:43 Message: Maybe I know why 310cure does not work: when the nuvi was still working I updated the firmware to v3.60 with webupdater and now the file gupdate.gcd was loaded in the nuvi's memory. Maybe I need a 370cure version to fool the present bootloader that considers the 370cure version more recent and puts the new software in place of the v3.60 Reply author: neadrenalin Replied on: 20 Dec 2007 18:53:28 Message: yes, you right, please share 3.60 version - to make from it 'rgn' file. I agree with you - ram loader can ignore older bootblock with our changed 'gupdate.gcd' name and stay newer version in flash. I think 3.60 will be enought for me and you to cure.But in my units that I flashed before I noticed always that bootblock changes.

Disconnect usb cable and Power off your device1...1a. Wait until Windows installs drivers for nuvi (this may take a long time, manual select for driver location is required sometimes)Keep in mind, that after 30 seconds nuvi shows calibration menu, and exits from the pre-boot mode.

Several of the more recent Garmin units provide a 'disk drive' when connected to the PC. Communicate with these units is accomplished by the PC reading/writing a file on the unit. G7ToWin does not support those units. Reply author: Hitec Replied on: 11 Jul 2008 17:46:42 Message: Ok, I have a related issue that hopefully this service firmware method might be able to solve. I've, uh, performed some surgery on a Nuvi 200 and added and additional 1G of memory. The maintenance screen shows 1G+1G. Unfortunately, I wasn't too smart about it and did not consider how I would get it to reformat the file system to use it. After doing a factory reset, the file system is kinda messed up, and I can't get past the "loading maps" without it rebooting continously. I tried all the 'cure' programs here, but it didn't do it. So I guess I'm looking for any way to reinitialize the file system and then to reload the system files back on. I'm happy to see that there is a way to get into bootloader mode, but now I have to figure out how to fool it into a initialize.

Same as main chip?Have you done something with main chip? (desoldering.. etc?If there is mess in file system you can do nothing now. No cure firmware will work.When I added second chip to N200.. I flashed/programmed main chip with N270 flash contents. (with Wellon VP-480)Im not sure if N200 can handle more than factory 1GB chip.Also sometimes when you add second chip.. diagnostic menu will show it.. but you will have no access to this space on Windows.You need to format whole Nuvi (DO NOT UNPLUG USB AFTER FORMATING)Sometimes you need to remove Nuvi partition and add new one with new size details.Bad news for end of this post.In 99% you have to flash main chip with some kind of NAND Flash programmer.But you need to have image of working Nuvi/chip.PS. I have some flash images.. I can share. Reply author: Hitec Replied on: 11 Jul 2008 21:15:11 Message: The original chip was a Hynix, but I couldn't get that, so I used a Micron chip, which as far as I can tell from the datasheet, is compatible. I did not do anything to the first chip. When I first rebooted it up, it appeared ok, and the maintenance menu showed 1G+1G. But when I plugged it into USB, two drives showed up, one the original 1G and another one that was inaccessible. I then tried the factory reset, thinking (foolishly) that it might reinitialize, but that made it worse. I think it was at that point that I could no longer acess it as a USB drive. In retrospect, I should have reformatted the drive and loaded back the files in one USB session, before I did anything else. Now I am unable to get into USB drive mode, though I can still load f/w with the Loader mode. My goal is to be able to get it past the bad files to the point where I can connect via USB and repartition, reformat and restore the filesPouchX, I was unable to email you for extra details so if you could try email me, that would be great.

One would assume that if the POIs were gone so would the detailed maps. Is this the case with your Nuvi? Or are you saying that when you search for a particular POI (Where To - Point of Interest - etc.) the Nuvi doesn't fine anything but you can continue to have the device route you to a selected address and display the streets on the map screen?

Reply author: SergZak Replied on: 20 Jan 2009 14:50:45 Message: @ dozerdudeAfter loading what kind of "map file"? A new mapset like US Topo? You can only search for POIs on maps that have POIs embedded in them like City Navigator North America NT 2009. If you're trying to search for POIs on a mapset that does not contain any POIs (like US Topo), that is the message you'll get. Make sure your City Nav mapset is selected (has a check mark in the box next to it): Tools>Settings>Map>Map InfoIn addition, the unit can still be routing you even if the City Nav mapset is deselected within the Map Info settings. It will use the crude basemap to route but the routing will not be of much value because of this. Reply author: NanaimoRick Replied on: 20 Jan 2009 20:08:24 Message: @dozerdudeYou would definitely need to have the City Navigator North America NT maps selected using Tools>Settings>Map>Map Info as SergZak states. That Mapset is were the POIs are located. Reply author: dozerdude Replied on: 20 Jan 2009 20:56:00 Message: Thanks, Guys. The light finally came on!

With modified v4.10 Nuvi is accessible via USB (I've deleted corrupted files) but it stuck repeating calibration procedure. After update to v5.00 using WebUpdater it keeps rebooting every few seconds. In either way there is no any messages at he bottom of the screen during power on procedure (copyrights, loading maps, etc).There is obviously something else wrong with this Nuvi.Edit: Finally done! Flashed original v4.10, then manually "updated" to v3.40 (device still shows v4.10 ?), then updated online to v5.00 - all is working OK now.Thanks to nadrenalin and PouchX for their work on this matter.This is almost the exact same situation I have, but I have been unable to resolve the issue.I had V5.0 on there and while trying to flash something on there I shouldn't have, I managed to mess something up. I have hardware id 834, and I get a constant reboot. Garmin screen shows for 1-2 seconds then unit reboots, again, and again...etc.Due to the reboot, I cannot get to mass storage mode. GUPDATE.GCD is not present on the device, as I removed it prior to this problem.I can enter pre-boot mode, and have been able to flash ver 4.10 and ver 4.10cure on there, but it still reboots. If I try to run webupdater when in preboot, it identifies the device and says it has version 4.1 on it, but fails saying that the download is corrupt. I left it for awhile rebooting with the usb plugged in and now it is just frozen with garmin displayed on the screen. No more reboots but I can't power it off or enter preboot anymore. I am going to wait till the battery dies in hopes that I can enter preboot again.Does anyone have the .rgn file for version 5.0 firmware? I am fairly certain that will fix it as it seemes that I was flashing the firmware when this problem happened. All the files on the device are proper and were functional.Using neadrenalins tools "unp2" and "merge105" on the GUPDATE.GCD file did not produce a satisfactory result. The fw_all.bin file that it created is 0kb and the boot.bin file is 304kb.Any thoughts or suggestions??Thanks.

Then flash rgn - this erases user memory to the initial state. Then use 5.0 again. Possible, but no more than 50% guarantee :( Published firmwares by garminfrance mostly helpful in case SSM (system software missing) problem for dedicated nuvi's model.I am glad to see that more than one person can use my tools for rgn creation, It is helpful for SSM problem.

It will no longer power up at all. It just stays dead. It is not the fault of the firmware, but I believe it to be an internal malfunction. While hitting the hard reset button, with the usb cable plugged in and the power switch held, it turned off, like it always does, but this time it didn't turn back on. I believe when it was stuck in that reboot loop before a few days ago, it damaged something. I probably could have saved it at tht time, had I not left it rebooting for so long. Now I am afraid it is finished.Perhaps I can buy a nuvi on ebay that has a cracked screen for cheap and swap out the parts.Do all the 2XX series (200/250/260/270)take the same screen? What about the 2X5 series (205/255/265/275)? Maybe the 5XX too (500/550). I know externally they look the same, but is the ribbon cable/connectors the same?Thanks again everyone for your help!!

After that, I tried upgrading to 5.0 original, and also 5.0 track log versions but these versions either :1) make the garmin stuck in reboot loop at the logo2) simply kept asking me to do initial setup almost every startup, after that, I am unable to change vehicles or navigation view(stuck at track up, but in the map it shows 3D and refuses to change to real track up or north up)3) froze when navigation and I had to press reset to turn it off. Results in lost favorites.These happened after I tried to upgrade from 4.1 to 5.0. I hope that the above "symptoms" I've described allow neadrenalin to guess what's going on, and possibly try to help. 4.1 is working fine for now, but it seems to get satellite slower than 5.0. Maybe someone can provide a 4.4 gupdate or rather, rgn as I am unable to find the gupdate.gcd for it.

It has glamour new interface like 2x5w's nuviz have.Other versions can not suit your device.Please follow http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=117599 and find necessary firmware there.Trying to update unit with something else can brick unit totally.

Agree with updater if any additional messages appeared.If LOADER appeared on the screen you may release POWER button and wait until unit flashed.After success flashing unit restarts. (if you used WebUpdater before - gupdate.gcd needs to be deleted too! because of unit automatic firmware update after boot if this file exists, now it is no need in it, we will made it manually)Now unit should boot! And there is only basemap shown (no gmapsupp, no gmapprom, gmapprom1 visible).And now you can attach it as a Mass Storage Device and DELETE wrong gmapsupp (or whatever you need).Then you need to make flash for usual firmware for unit. I prefer usual firmware loaded in PRE-BOOT mode, I hate gupdate.gcd :)So, download the filehttp://e-trex.info/fw/nuvi/2xx/fw_nuvi2xx_en_v260.rarand use it as I described above.Now your nuvi is fully operational and have no "bad maps".2geeks.

I have been reading this thread for a long time, but I am unable to get any further with my problem.I deleted files from my nuvi 250 to try to fit a larger map on internal memory. Map did not fit, so I left it with no map and turned it on. Now, I was getting the problem described here. My nuvi would start, not find maps, restart, not find maps, restart and so on!Also, when I entered PRE BOOT mode, the device appeared briefly in Device Manager, but it was not seen as a drive.I took advice from here. I added a new map called \Garmin\gmapsupp.img to a Micro SD card and put this into my nuvi. Success! My nuvi started and it seemed to work. It can navigate properly. But I cannot search for city locations, and I have no speech files.Now, I still have the problem where it will not be recognised as a USB drive!! I have all original files backed-up but I cannot put them onto it. g7toWin says the Software Version is 5.0 and the Hardware Id is 851. It is strange that it navigates ok - but will not be seen as USB drive. The USB connection must be OK because it is seen briefly in PRE BOOT mode.I could really use some help on this!

If you've formatted your 250 and do not have a complete backup of your unit then you are probably out of luck. Although it's possible to restore most of the files by connecting your Nuvi to a computer and running programs like Garmin's Webupdater, it is not possible to restore the map files to the GPS without purchasing then from Garmin or an authorized Garmin reseller.

Espero que te resuelva el problema, saludos Reply author: NanaimoRick Replied on: 03 Aug 2012 17:27:56 Message: The above translates to:Mattiash Hello, I end up discarding the gps but maybe I can help you to try with your GPS, the idea is to update the firmware of the GPS, you got several ways to connect the gps if your pc recognizes it as upgrading from webupdater of garmin, if the pc will recognize it but the webupdater not updated, you use a software called firmware updater and a. bin that you can download from this forum.The difficulty occurs when the pc does not recognize it, then you must use the same program with a firmware updater. Bin and for the updater Acknowledge what you need to connect the GPS to the PC and turn on the gps and hold the power button for a period long, squeeze it in the updater autodetect button until your GPS and hold the power button when it appears in the updater squeeze it ok and that you are sending the new firmware to your gps.

Although it maybe possible to obtain a working map file, it would not be possible without being in violation of copyright laws.
