Confirm that b/l 5.5128 was actually installed. What brand card are you trying to us?

sandisk card, how can i confirm BL as its doesnt have a bif file yet to open as the device hasnt booted

Thu Nov 25, 2010 7:30 pm

device say bl 5.307(chksum 8307)

seems it is the bootloader that is the issue, but im confused as to how i update it, copied the 5.5128 system file to the card and the device still would not see the card, so how else can i flash the bootloader?

start it with your old sd-card if you have it ? and you see bootloader version. install new bootloader with this old card if needed
system file need to be only one boot in sd-card then you dont need it at all

EDIT: i see you must update bootloader

i use an sd card with a sytem and map on it with the updated bootloader insert it in any tom tom and it will update the bootloader file to the tom tom.
I then shut down tom tom and insert sdhc and it finds it every time
