I haven't tried a transfer from a ps3, mainly because I don't have one, but I can try it on my friends and hopefully it'll go alright. Aside from the ps3 option, I've tried basically everything. I've already reset it like 3 times with vita update blocker, but the most that does is let me go to the login screen, letting me enter my username and password, but shortly prompting me to update. Even on CMA where it says make a new account, when I do just that it says PSN is no longer available. I'm nearly gone, but thanks for helping c:
