Messed up TomTom One V4 :(

**darknite** · 6th January 2011, 05:29 PM

Hello Noemaners, I have messed up my TomTom. It does not have a memeory card in it just a built in flash. I deleted the contents after connecting to a computer (I did copy everything over except the maps). I then ran autonavcore 8.5 from this forum and moved back the ttgo.bif file. I then tried to boot it and it loads at the bottom and then crashes on the loading screen. Do I have to update my bootloader aswell?

Thank you.

PS I have tried to search for help but I cannot figure out what I have done wrong.

1. Download SE Navcore 8.412.1236 from here [Only registered and activated users can see links. ]
2. Download new map here [Only registered and activated users can see links. ]

3. make backup copy your tomtom
4. run navcore AutoInstaller and replace all file
5. delete your old map folder and copy new map folder to device
6. start your tomtom one time
7. plug it back to usb and run AutoActivate in root directory
8. start your tomtom again

bootloader version 1.xxx, do not ever change it or you can make it paper weight

If you have a Tomtom with the bootloader version number starting with 1.xxx instead of 5.xxx you have a special system and should
never attempt to change your bootloader! It is most likely that you have a special Navcore version as well - 8.041

Other Navcores won't work on your device the progress bar will stop at the end end the devices freezes.
The only way to use non genuine maps on these devices is by using a specially patched PNDNavigator for for the 8.041 Navcore.
Don't try to patch the ttsystem or the PNDNavigator file yourselft it won't work and the ttsystem does not need any patching.

Only the new PDA maps will work as you need at least Navcore 8.2xx for the full featured maps.

Link for the pre-patched [Only registered and activated users can see links. ]

The bootloaders 1.0100 and 1.0200 are designed for devices with a "bug" in the filesystem or the GPS hardware.
Tomtom has provided this "quick" fix to be able to sell these units (most of them being ONE V8 models) without sending them back to the headquarter in Holland.
If you bought one of these units and you are still in your warranty period ,try to get a replacement unit with a normal bootloader/Navcore as it is most likely that Tomtom won't offer any updates for those devices!
