Because some guys asked me about a TUT how to install 6.20 PRO-B5 Permanent, I made one.
Works on PSP 1000, 2000, 3000, 4000 or PSPgo!
But your PSP Unit must be 5g or lower!
I tested it by myself on a PSPgo ;=).
For this, you will need:
- PSP 1000, 2000, 3000, 4000 or PSPgo
-
6.20 PRO-B5
-
Official PSP Firmware 6.20
-
6.35/6.31 to 6.20 Downgrader if you aren't on Firmware 6.20
-
PSP Module Checker 3.0 to check your PSP unit
Tutorial
1.Extract the downloaded archive.
2.Copy the
620PRO_Permanent,
PROUPDATE and the
FastRecovery folder to PSP/GAME.
3.Launch the Update
6.20 PRO-B5.
4.Press
X to install the 6.20 PRO-B5 CFW.
5.Your PSP is rebooting...
6.Launch the Update
6.20PRO Permanent..
7.Press
X (now there's a warning, ignore it, but you can backup the file if you want for safety reasons)

and then
O to install the 6.20 PRO-B5 CFW Permanent.
The secure way:
8. Congrats...now you're on 6.20 PRO-B5 Permanent, enjoy it

.
Uninstallation:
1.Run the 6.20 PRO-B5 Permanent Installer again.
2.Press
X to uninstall the Permanent Patch.
But the vshorig.prx must exist at ms0:/ or ef0:/ vshorig.prx.
Problem-solving:
There's a Recovery combo to uninstall it:
While starting your PSP hold ◯ + x + START + SELECT to uninstall the patch!
Note: If you want to skip the Sony-Logo at startup, hold
R while starting the PSP, now you're in the Recovery Menu.
Go to Configuration and enable Skip Sony Logo
Note2: While starting your PSP and holding
SELECT you are on OFW 6.20 again

It took me 1 hour to write and test it, it isn't really difficult to say just thanks
