Backup of reg 41 was successful. Taken from 'converted' 3790.For NVram backup you need to have a copy of region 41.
Does the conversion 3790->3490 cause a change to reg 41 content?
Does converting back (3490 ->3790) restore the 3790 reg 41.bin to original
Trying to decide if it is worthwhile temporarily restoring my unit back to 3790 so as to backup original reg 41.
NV is changing all the time. What is important inside is model number, ID, registration code and unlock codes, you can see all in GarminDevice.xml. This doesn't change when flashing 3790 <-> 3490.
hi again, was reading post #1 of this thread is it safe to assume to go ahead with
Another way to convert 34xx with logo and enable features :
Flash full 34xx firmware
Unpack the file to an empty SD card, turn nuvi off, insert card, turn nuvi on.
and to return to 37xx ,its logo included:
Flash full 37xx firmware
same as above,unpack the file to an empty SD card, turn nuvi off, insert card, turn nuvi on.
without going to the pre-boot?
Once you learn how to convert nuvi , you should learn about preboot mode.
Thanks to everybody that helped, glad i went to this forum.
