ok, I update to the next firmware Mio s501 and Mio, s568 both are going on s505, but my problem persist. my touch is not going till the edge, on the right and left from the screen. 480x272 resolution it is like 460x272. What can I do?
I save my previews file.img (128 mb) but wen I putted back the mio freeze on the welcome screen (so I had to put back the firmware from the first page).

any advice will be more then welcome.

Marciport, meantime I found (and tested) that s3c2443_nr works fine and you can have a physical block dump without jtag. Run it in a good device from sd and reset after 3-4 minutes, otherwise will dump the entire nand. If pages.hex has more than 1,5MB then is OK, cut it at that size (from 0x180000 till end) and flash this in the bricked one.

BTW, in case you manage to make this dump from a working Moov360-N179, please upload it somewhere and leave a link. I would be gratefull to have same from a Moov330-N179 and get rid of the brick from my desk...

@ ablbd: Thanks, i'll change flash chip with K9G4G08 and try to flash it.
Btw your program write ecc in spare area or only main area? I read in S3c2450 datasheet that iROM copy functions check ecc for first block on boot and only if is ok load it in stepstone ram and jump to it.

@ventzel: Yes, sjf2450 is calculating 4bit ECC and is filling spare area for every page it writes, including block0.
If you look into hjtag driver, that one will NOT fill ECC although would not be too complicated to modify the page write function, use the controller-generated ECC and write that into spare area.

As far as I know, this phase is accomplished by hardware and the 1'st block is loaded into CPU's internal ram without ECC check!

extra question:
I have the preview .img file saved via RWDisk. What will be the steps to put backed back this .img? The size of this image is 168 mb. or this is just the img of the Flashdisk (and do not contain the old firmware)?

@ablbd: I read this here
http://www.samsung.com/global/system/business/semiconductor/product/2010/4/16/256549S3C2450_51_16_IROM_ApplicationNote.pdf
and in user manual of s3c2450 page 174 http://www.samsung.com/global/system/business/semiconductor/product/2010/4/16/236200UM_S3C2450_rev111.pdf
I think 8 bit ECC is used.
If i read flash (main area +spare area) and i write it into same type of flash assuming i don't have bad blocks i tink it will work. Or maybe i got same file if i merge Pages.hex and Spares.hex read with S3C2443_NR.exe?
I modified a H-jtag driver just to read and write entire page area (main+spare).

Before presuming 8bit ecc, calculate!
Spare area size is fixed by the nand producer(in your case, 8bit bus!) to 16 bytes for each 512 bytes of data (so-called sector). 4 bit ECC consumes 7 bytes and the remaining of 9 is used for meta-data. 8bit ECC would need 26bytes only for ecc itself! Data sheet is mentioning the fact that 8bit ecc is possible and not that is compulsory.

GelullaBarr,
Unfortunately I don't have another software to SMFlash backup ... (DiskRW is the only one).
But can you tell me what is doing (and where is not behaving like it should)?

Hi, g_alin

I saw on page 24 that it is possible to adjust (calibrate) the touch screen.
For the moment, it is very frustating that I can not tap on the hole screen.
So please, can you spend a bit of time on this(to help me to fix this issue)?

thx in advance

g_alin...DiskRW it's not responding, it's not doing anything, no error, nothing, and I found on this forum that Ndump should work on windows 6, but the same result

GelullaBarr,
If is not doing anything ... probably some components (dll file ... ) is missing from OS ... Your GPS is unlocked (with miopocket ...)?

white_flag,
If you have the original SMFlash upload it somewhere and I will try to extract the firmware ...
The information is in registry: HKLM\HARDWARE\DEVICEMAP\TOUCH\CalibrationData (so you can overwrite that data to have the corrected parameter ... but I need the SMFlash to tell you what to write ... )

DiskRW will NOT work on CE6, makes no sense to try. Some IOCTL's used by diskrw are forbidden in CE6.
NDump needs compact framework and rom(\Windows folder) must contain mscoree.dll & ole32.dll but from some feed-backs it looks like is not "seeing" SMFlash due to the fact that in normal operation mode SMFlash is not mounted...

@ventzel: You were partly right; if the device is equipped with k9gag08 nand (128 bytes spare area / sector) then it uses 8bit ECC. Trying to debrick the Moov330, I got an s3c2443_nr dump from another Moov330 but it didn't worked because that one had k9gag08 nand and mine has k9lag08. For me is bad luck but can be a solution for you: I am 95% sure that this dump will work in your Moov360. You will need to flash only 2 blocks (1MB) and, of course, the spare area for those 2 blocks.

http://www.4shared.com/file/AVZgmLMm/Moov330IplSpl.html

In case you will not be able to flash with hjtag the spare area, let me know and I'll include a "special option" into sjf2450 to write page+spare area from the 2 files.
