But it does says success in the log

@Greengame
In sd root you should now have 41_backup.bin along with the Garmin folder.

In Garmin\Updater\xxxx along with Ldr.bin & update.txt you should now also have last_id.bin and update.log, showing:

nüvi xx Software Version x.xx, UID: xxxxxxxxxx, HWID: xxxxxxxxxx
------------------------------------------------------------------------------
Parsing "rrgn,41,1:/41_backup.bin"
Success

catymag, i followed all the instructions and it seems like everything worked fine. My 3790T backed up as 41.bin as one other user has posted it and it has the same file size as yours in your attachment in your post #28. Since the update.log says it was a success as you wrote , i take it, it worked. I never flashed my device but as all of you wrote, i guess it is a very good idea to have a backup just in case. Great instructions.

tried to back up my Nuvi 3597LMT but it seems like one file is missing. i don't have the 41_backup.bin on the sd card next to Garmin directory. i think this is the most important file in the backup file. however, i can see 4 files on the HWID directory, last_id.bin, Ldr.bin, update.log, Update.txt
the unit rebooted as normal but it didn't say if the backup was succesfull. am i doing something wrong?

Hi!
I have a question:
where is boot logo located?
I have 3760 BWM edition with BMW start logo instead of Garmin logo.
I created a Backup of area 41 with BMW logo.
Then i converted it to 34xx with 710 firmware & BMW logo went away.
I need to restore this logo (if possible) & want to know how?
Restoring original area 41 doesnt restore the BMW logo................

Use rgn_tool to extract boot.bin from your original firmware (gupdate.gcd) if you have a sw backup.

You must create one for 34xx coz 37xx one is different.

Coz here was off topic and it had nothing to do with region 41.
