Tomtom Go 5200 / Go 520 freezes & restarts
Hi, i bought a bunch of satnavs nav5 tomtom 4pn50. Some of them I managed to fix, some had broken LCD's and others straight just not updated (by some I mean 2). I have 4 of them that keep freezing and restarting after 15 seconds. The devices were on charge, they boot up, drums sing, normal booting time, you can actually go in the menu in those 15 seconds time frame, but after that it freezes and proceeds with a restart. It does that over and over until I shut it off. I have tried the recovery mode with keeping the power button pressed until the white text on black screen appears and then tapping the power button 3 times to go to recovery. The computer recognizes them. My drive connect starts up, completes the % of recovery, the device stays like 30 seconds to do its setting after being connected to the PC and then does the same stuff (freezing and restarting). Any ideas how can I make a factory reset from the computer because it doesn't have enough time to do it on the device? Or is it a corrupted memory ? If I can access the internal memory to patch it I think it might cure it. Any idea would be appreciated.
Thanks!

EDIT: I've found out that all the rebooting ones, all 4 have the same navcore 21.202.0006.411(0) released on 27/05/2022
EDIT 2: I've fixed them. I just reflashed version 21.100 from this guide and all 4 of them are now not freezing and not rebooting. (no sleep in the night and having something to do made me fiddle with them more). I'm leaving this post to whoever might be in the same situation I've been in.lockeagle Reviewed by lockeagle on .
