[PSP Tools] How to Install 6.20/6.35 PRO-B4 ☺

Coldbrid &   have just released PSP Custom Firmware 6.20/6.35 PRO-B4.  To run the CFW just run the PRO B4 update. To make it permanent, run the compatibility check first, run the 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.
If everything is working fine, then just run the patch and make it permanent.

6.20 PRO-B4 & 6.35 PRO-B4 changelog:
  • Added 6.20 OFW Kernel Support
  • Added 6.20 Type 2 PRX Permanent Bootloader
  • Improved NID Resolver (Including 6.20 <-> 6.35 NIDs)
  • Improved Game Compatiblity via Anti-NBGI Fixes
  • Added Inferno OSS ISO Driver (Improves Compatiblity and Speed)
  • Fixed BGM Playback Bug in Recovery Menu
  • Improved Satellite Permission Detection
  • Fixed Skype Crash Bugs
  • Added Custom PSX Manual Support
  • Added version.txt Display Support
  • Added Parental Level Check for ISO / CSO
  • Some small fixes we probably forgot about…

How to permanent patch the CFW:

  • Pressing R while booting loads the recovery.
  • Pressing Select while booting loads OFW.
  • When applying the Permanent Patch, choose X on first question and O on second to install, two times X only tests whether your device is compatible with our Permanent Bootloader.
  • Should you manage to brick yourself, try pressing O+X+Select+Start while turning your PSP on. It will trigger a emergency uninstall.
