hi there. about a month ago i trashed my 2016 omnia with some nOOb wireguard stuf, and had to factory reset it. It went back to 3.12 or something. I tried the 3 to 5, and that went wrong…but you do not brick it. When it goes wrong you just need to fact reset it. It keeps breathing.
My tip would be to simply flash your unit with the latest 5.x med kit if it does not work? But to brick it you need to do something far worse than all this. Problems updating from 4.0.1 to 5.2.3 - #3 by DIKKEHENK
