Thread: IMPORTANT! If you want HELP in case of a bricked Garmin device, please follow this

Well that's inconvenient. Last gasp is to erase region 41 in case it holds poisoned data which is preventing functionality. If i thought i could do anything constructive with your 41.bin i'd ask to look at it first, but unfortunately i don't know of any way to 'clean' the nonvol even after decryption. Be aware that if erasing does work there may be some device functions limited or lost and it may identify as "nuvi 13xx" instead of "nuvi 1310" on start screen. The device writes to region 41 on every successful boot. There is some data that it can write/overwrite but some data cannot be replaced. As you already have a copy of 41 on the card, you could try to flash it back using "xrgn,41,1:/41.bin" and "reboot" commands to test if it can write to the region (it will do in a healthy device, as 41 isn't protected in 1300 series), then run "ergn,41" & "reboot". Of course if the device is restored by erasing nonvol, then flashing back the corrupt data will only brick it again anyway.

As always, it's your call to proceed and at your risk if you do of course.

Nothing obvious in the XML. Here's the kit: [Only registered and activated users can see links. ] ; [Only registered and activated users can see links. ].

Instructions:

• Find a smallish (4GB or 8GB is good) microSD and CLEAN it by re-formatting as FAT32.
• EXTRACT the above files directly to the card by double-clicking "SD_Flash_Original_FW.part1.rar", part 2 will follow automatically.
• Unsure the device is fully OFF, not just in standby. You'll likely have to force it off by holding the power button for between 10 and 30 seconds.
• Insert the card into the device and power it on by connecting to a suitable 5V power source (NOT a computer USB port of course).
• You may not see anything at all on the screen other than what's been showing previously. Leave the device powered and wait to see if it boots up to a normal display. Leave it for at least several minutes to see if it finishes successfully.

Good luck.

Erasing region 41 did not help ether as most probably it could not be erased. Update log is a bit strange (without report for success of failure), but unit did not change its behaviour.
nьvi 13xx Series Software Version 6.30, UID:xxxxxxxxxxxxxx
Parsing "ergn,41"

For the record I repeated the procedure 3 times and get one and same result.
I think that was the end of the rescue mission - right?
