My 2450 just started doing that same behavior last night. I was plugging and unplugging it to the computer multiple times. It got stuck in that loop.... eventually, it came back to life.
I grabbed the latest firmware....
It has done it one other time (after upgrade)while being hooked up to the mini USB.
Crossing my fingers this isn't too serious. The unit isn't that old. |

Do you still have your nuvi 760 with you? I can try to help you one more time. There is one interesting idea I want to try in real world. Just tell me Unit ID and I'll send you firmware. |

Don't post your nuvi ID here, use private mail for this.

| I briefly encountered this strange behavior on my 760 recently also and it "normalised" when I removed the SD card. Still trying to find out what was the problem. |

| Likely to be a corrupted file on the card |

Have you tried to contact kunix. Think he is one of the few in the internet who can help you fix your nuvi. Have you tried his tool GarminCure3:
http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=143809
It is really awelsome!
Yes Kunix is helping me and I THANK HIM for that!!! He is the best I see!!!
My case is very difficult.... We are trying together, sent me files, etc etc...
I posted again my problem because i missed him, but he is back
I saw GarminCure3.exe but I don't think that I can do it myself....
Thank you and keep in touch |

I have the same problem with my older 760 model ( I also have a 3760LMT).
I can get into pre-boot mode, have already used the PouchX firmware 3.20 and 4.60, as well as the 5.30 version I found recently. Last year, I remember trying 2.2 or 2.3, before I gave up on it and chucked it in the closet.
Yesterday, after reading this and many other threads - I tried again.
AFter I've installed the CURE'd versions of PouchX's 3.20 & 4.60 (using G-Cure 3 to make it), the unit reboots constantly.... (Should I wait longer than 2 minutes before shutting it down?)
When i installed the UNCURED (original firmware) - It boots but doesnt go as far as MAPS LOADING... it just stares at me, with that Garmin LOGO.
I can't seem to get it to be recognized as a USB drive.. so I can't even go in to the unit to see what files may be corrupted.
What am I missing or Overlooking? |

| Try correcting in the firmware the strings describing the memory drive 30 00 3A 00 2F, 31 00 3A 00 2F, 30 3A 2F, 31 3A 2F to 00... Don't use old firmwares as they can harm your nuvi. Keep in mind that there can be a problem in the memory (hardware issue). Good luck. |

@Animal
Just to be sure, was your device connected to PC while running CUREd version and constantly rebooting?
Also when trying ddabcd277's advice make sure NOT to CURE the firmware.
The advice doesn't make any sense with CUREd firmware, because it doesn't read any files from the internal filesystem. |

Create backup of your nuvi
