Thread: How to backup Nuvi NV (region41) with sd

I've just noticed your post [Only registered and activated users can see links. ]. Seeing you've been able to use the Ldr.bin for HWID 3433 to dump regions, it may be possible to fully convert to HWID 3433 by flashing an RGN file in preboot or use xrgn commands to flash the BIN components. The "K" version limiting the use of TT15 collars may then be overcome. There's still always the chance you'll brick it of course so all risk is yours naturally. Best to compare the fw_all 14.bin and logo 16.bin from the fw with the ones you've dumped, i'm tipping there will be some difference ... most likely in the logo region (decimal 16/hex 0x10). Use a hex reader or compare hashes.

I did backup for all regions on Alpha 200i K few hour ago.

There are backup just for regions 5,12,14,16,34,43,45,48,83,144,152,154 and 180.

I have error message for regions 3,10,17,19,21,44,46,49,50,51,74,75,76,77,90,93,99,100,102,123,131,134,135,136,166,245 and 248.

I have message "Success" for all other regions from 1-255, but they have 0 byte size.

I hope that this informations are useful for somebody.


@Butters Thank you for help again!
