I followed priestiality's way using Storagemgr to run sd2vita on psv1000, it works.
But when i close my vita's screen for a break, it sometimes auto wake vita's screen and all the plugins and games broke,
that i have to reset my vita and run the exploit again.
It really bothers me a lot...
only ps5 updated to latest firmware can go on psn, jailbroken ones just don't use psn or they risk getting flagged or banned, altho spouting profanity in online play alredy does that
