Pro620Bootloader
The 620 PRO Bootloader Installer is a application which is part of the PRO CFW Project.
It installs a custom replacement XMB shell which exploits a security flaw in the Runlevel Execution of the 6.20 Kernel to auto-execute a QuickStart on system start.
Hold SELECT
button during the bootstrap it will boot into OFW.
Hold O+X+SELECT+START
during the bootstrap the perament patch will emergency uninstall. Use it as a last resort.
What's changed after 6.20 that this doesn't work on later OFWs?

this 6.20 PRO permanent is only work with psp that have this module [1g,2g,3g,4g,5g]. check ur psp's module first to comfirm this 6.20 can run in ur psp. download this module checker here http://www.mediafire.com/?9wa4glvetm8ij00 and put it in ur psp game.

Hello. I have a question about vshorig.prx: I accidently activated the permanent patch twice so it seems that the vshorig.prx on my stick has been created from the already patched firmware (6.20). Is this file bound to the the PSP it originally came from or could I use any vshorig.prx? Or is my vshorig.prx on the stick still of use?

heres a question, i have a psp 3k 4g (GoW Ghost of Sparta) it was on 620 pro then i updated it to 660 but now the lowest i can downgrade it to is 635. i have tried the most recent downgrader and nothing happens. it'll tell to hit X to start the SCEA thing and all it does is take me back to the XMb. my question is can 620 be permed to my psp if so can any of ther other CFW be permed

I'm not sure about why you can't downgrade to 6.20 (the most I've downgraded on my Go was 6.39 to 6.20), but what I do know is the 4g PSP 3000 can use 6.20 (and 6.20 PRO for that matter) and can be permed. 6.35 above can't be permed on it, however, as the exploit used was patched on those firmwares.

I think they should make a permanent bootloader for 6.60,6.39,etc for psp go,3000 and psp 2000 v2
