I've found the global.cfg file and changed it to usbmode=0
There's also some files with a quite similar name: global.cfg.back, global.cfg.bak, global.cfg.orig
Should I change those to usbmode=0 as well?
And I was more wondering now that I have access to all the system files again, if there's anything I could still do there. Or does a hardware failure really mean it's something you can't fix yourself?
I saw someone with a similar problem to mine here:

But unfortunately from all the files I can find, I can't seem to locate wall.cache
