I have recently purchased a PS Vita PCH-2003 running the latest firmware. Is there anyway I can downgrade this so I can play my backed up PSP/PS1 games???
When an exploit becomes available for 3.70 you may be able to use modaru to downgrade to 3.60, until then sit tight and don't update. The flow is eventually releasing a kxploit for newest firmware. Should be by end of year.
