I managed to backup my nuvi and got these files: last_id.bin, Ldr.bin, update.log and update.txt

with the update.txt content:
rrgn,41,1:/41.bin
reboot

and update.log:
nüvi 2xx5 Software Version 8.20, UID: 38655XXXXX, HWID: 38655XXXXX
------------------------------------------------------------------------------
Parsing "rrgn,41,1:/41.bin"
Success
Parsing "reboot"

My model of nuvi is the European 2445LM.

After trying to enable some featuers in my nuvi, I found out that my bluetooth was not able to be activated and further more, my gtm 25 is no longer being able to detected. I decided to restore my nuvi to its previous state by changing the update.txt to:

xrgn,41,1:/41.bin
reboot

and place it along with the 41.bin file created in the backup stage.
the location is Garmin\Updater\1371\

However, after inserting the microSD into my nuvi 2445LM, it didn't boot into the software loading mode but loaded as usual and may I know what I have done wrong?
