Stuck Garmin Fenix pro 6

[rumennik]

Hello. I have a GARMIN FENIX 6 Pro. The problem is that it can't be updated by any standard methods and it can't undergo a factory reset. Let me explain. I manage to update the device with WebUpdater, it says it's successful, but it's not really... after a restart, it's the same version again. I give it a factory reset with all data erased, it starts as if it has been formatted completely, but after a restart, it restores all the old data... even the log files remain. I've tried all available methods online, but I must admit I'm not very experienced with flashing, etc. The watch has great sentimental value to me, so if anyone is willing to help, I would even give remote access to my computer if they could at least try to fix it.

Hello
Write to their support
Hardly that anyone can help you from any forum, considering that it is a smart watch with its own system
You will probably even have to send it for RMA

Yes, i second the above opinion. Unfortunately that sounds like it's probably damage to the flash memory anyway.

If it's running usual Garmin proprietary OS and firmware and you can also determine which is its nonvol region (41; 154, or ??), you could dump a copy of its data if that's even possible, and if it is possible then erase it to clear any possibly badly corrupt data. I doubt those devices can even dump regions successfully though, even if they run traditional garmin os/fw, unless it's got a hidden RWFS partition in the flash to copy to. You could look at it's firmware and if it IS usual garmin type, check if it has rrgn and ergn commands written in it to dump and erase the nonvol region.... but if not it's probably toast whether it's physical damage or corruption, sorry.

Garmin's exchange program might be your best bet - they don't repair and return, only replace in kind.
