We mentioned a while ago that developer TheFlow had announced he has a trick to create PS1 bubbles (a way to run unsigned PS1 binaries from your vita live area screen). TheFlow recently stated that he will release this trick for firmware 3.50~3.52. His trick relies on the same “rebirth” method that had been used by Qwikrazor87Major Tom and Mr.Gas [update: apologies for the mix up here, I need some sleep].
TheFlow also announced that he found a 3.57 (ePSP) Kernel exploit, which theoretically could work for the PS1 Bubble trick, but he will not release that exploit just now.
@MrFwibbles yes I found a 3.57 kernel exploit however I decided to release a method that does only support 3.00-3.51
The PS1 Bubbles trick he’s using was patched in recent firmwares, but will work for any of you up to 3.52. For those on 3.51 and below, he recommends using the rejuvenate hack with his very own VitaShell
