TomTom XL v9 red circle white cross

Postby xaueadeus » Fri Nov 03, 2017 9:54 pm

Hi,
i have a Tomtom XL v9 that dont go past a red circle with a white cross, my friend was updating the tomtom and may have changed the bootloader and navcore but not sure.

what i have tried:
downgrade bootloader (0.0..0 and 0.0..1) - does nothing it cant read the file
full format the tomtom and restore from tomtom home
diferent navcore
tt clear flash
reset (30 secs on power)
etc

the current bootlader according to black screen with info is s5.5011

i'm starting to think the memory chip is gone bad, since it cant read the contents from the bootloader.

any ideas so i can try salvage this unit?

thanks in advance

Thanks for the reply! I'm starting to think that would be the best and least "painfull" way to go! :lol:

Do you know if there is any info available on the "dark arts" of reprograming the bootloader directly on the chip using a programmer?

So i just tried the tool not used the navcore provided and it worked :D Low level format the memory and then reload the backup to the deviced and it booted ok.
Had a little trouble at the begining, it was showing some errors during the low level format but i think that was problems related with the usb port/cable not doing a solid conection!
