@zenarch: Well some time after that I find it can be lot worse

If you are experimenting, buying some pre-made EDL cable is probably good idea (You can make one with some soldering from any USB cable, but it just about $10 and it will make things easier when things go wrong).
Anyway, did someone here already got that 2025-12-22_15-51_4.1.1-rel_1222_1b15acb55 update? Nothing so far here.
Getting link to the update could be also good.
