PSP Custom Firmware 6.20 PRO-B4 & 6.35 PRO-B4. Perm CFW!
It’s what many of you have been waiting for, thanks to coldbrid & Virtuous Flame aka Liquidzigong who have just released PSP Custom Firmware 6.20/6.35 PRO-B4. With 6.20 PRO-B4 you can permanently patch 6.20 PRO-B4 into your PSP flash memory! Many changes in this custom firmware. To run the CFW first run the PRO B4 update. To make it permanent, run the compatibility check first by running fake vshmain to see everything is ok. This will check to make sure your PSP model is compatible with the perm patcher. It will reboot into PRO-B4, if it doesn’t or it crashes or reboots into OFW. Don’t use the perm patch!
The perm patch is only for 6.20 FW, so if you really want to perm it. Downgrade to 6.20.
Wondering about compatibility? Well here’s the list: 6.20 CFW PRO_B4 works on 1g, 2g, 3g, 4g and 5g models & CFW 6.35 PRO-B4 works on all models upto 9g.
Make sure you read the perm-patch notes below, specially if you manage to brick.
