Hm... either the forum ate my message or it still has to be approved. Sorry if this shows up as duplicate, I'll keep it short. Just reconfirming something, anyway.
I successfully jailbroke my PW2 after updating to 5.12.2.2, installed some other things successfully, tried to install RP and CRP with MRPI (RP failed, CRP went through), rebooted, now I'm stuck at the tree. Which I assume means one more reason to finally learn soldering
It's not a high priority since the device was collecting dust already and I did this randomly on a whim, but if/when I get around to fixing this, I'll try to remember to post the crash log. Cheers and thanks for the helpful resources so far!
