No, I didn't backup the reg 139/140. and attempts were made several of times without success with reg 41 restore.
1) Do you remove last_id.bin?
Yes, I did.
2) 1:/41.bin mean what 41.bin must be in root on SD...
Yes, that's the file created when I made the backup for my nuvi with:
My problem is, I plugged in the gtm 25 before enabling some features in the "Enable features in nuvi 22xx, 23xx, 24xx and 24x5 & 25x5" by catymag and everything related to the traffic seemed fine. But after enabling, at first I noticed the bluetooth symbol where my nuvi didn't have this feature before, however, I couldn't connect my phone to the nuvi via bluetooth. I didn't check the 3d terrain, building. and definitely I didn't see the option of playing mp3, except the audiobook player which preinstalled in my nuvi and neither the video player. After checking with second gtm 25 (with european traffic subscription), I can confirm that my nuvi has no longer have the traffic info option. When every time when I plugged in the gtm, it acted as a power cord.
This is what I created in another microSD: :\GARMIN\updater\1371\
2 files were within the 1371 folder:
with the line:
and reg_140.bin (20KB)
After inserted into my nuvi and reboot, nothing happened. It just loaded normally and bluetooth option is still there but not able to be enabled. And traffic info (i will check with gtm 25 in a while and report)
