PSP Custom Firmware 6.20 PRO-B4 & 6.35 PRO-B4. Perm CFW!

Share

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.


PSP Custom Firmware 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 perm 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.

We flashed and patched 6.20 PRO B4 to our PSP Go 5g without issues...

      How u run ur update pro. just run back the Update pro. does you get any kind of error when u install it?
      do know if your run it from 6.20tn-d u have to revert back to OFW6.20 by uninstalling 6.20tn-d. Then only you can run and another thing is Flash0 must be disabled then u run 6.20pro-b4 update.

    • Rain

    One question. Has anybody played Chrono Cross all the way through on this cfw? I just wanna be prepared for any errors I may stumble upon, because it’s one of my favorites.

    • RhymeP

      i hoped that this cfw will solve problem with cc, but did not, still crashes while dueling the first boss

  • Alex

    Does anyone know how to run a UMD that requires 6.37 OFW on this CFW? Everytime I press play it won’t let me unless i update. Is there anyway to play that game without having to update or turn it into an iso?

    • Navin

      Well Alex,

      have you tried inferno driver and plus try to play around with recovery menu. I have no problem at all. My PSP 3006 Brite TA0.93 v3.0 G4 6.20 initially then 6.20tn-d then revert back to 6.20ofw and now best of all 6.20Pro-B4. Well I can play my umds and my iso/cso without any problem even PSX games no problem at all.

      • Alex

        I’m pretty sure I can play my old UMDs and iso/cso, I just want to know if I can play the newer umds without having to revert back to ofw

    Need HELP Please..
    i have a psp 3001 6.00 when i first got this then update it to 6.20 for me to hack it. i followed the instructions on how to install this correctly. i created an ISO folder at the root and dump dinerdash.cso and worms2.iso at that folder that usually works fine in my brother’s psp 5.03CFW, just to check if its working. i already got 6.20 PRO-B4 in my system and even got the perma patch correctly. but when i check the game it gives me a CORRUPTED file.
    did i do wrong? what should i do to resolve this?i’ve been trying to figure this out for almost a week. i would really appreciate the help..THANKS A LOT!

    • Navin

      Hey bro just redownload the game iso from proper website, well did u copy from ur brothers game.. It means it is old CFW patch not the latest one. so u will get corrupted file.

      • anGie

        THANKS A LOT! it’s working now. i greatly appreciate your help! btw its SIS. =)

    Greeting Brothers,

    Again I am going to Post the Difference but now it is between 6.20Pro-B4 and 6.20Pro-B5(Both Permanent Patch)

    Well There are quite some differences in 6.20Pro-B4 and 6.20Pro-B5

    1. The most significant is the start up of your PSP from shutdown, It is no longer skip the startup but this time the startup is a CFW startup and it is pretty cool.

    2. Games still runs well and this time whenever you start a game u will see a CFW game boot and damn cool. I really like it.

    3.You don’t have to downgrade to OFW 6.20 again. Well you can directly update to 6.20Pro-B5 by run the ‘Proupdate”(A test for ur PSP is compatible or not) first. Well here again u press X twice when it prompt. When it goes to ur XMB/PSP screen then it is means your PSP is successfully installed a standard 6.20Pro-B5 but not the permanent. Well you might found it will hang and need to restart ur psp. Just don’t worry restart and just go on installed the 6.20Pro-B5 permanent patch and this time as usual Press X and O when it prompt.

    4. Well it is still unable to support the FUSA_SD fullscreen plugins. That means you have to hang on untill they solve this issue.

    5. Games will not start or playable if you using a not supportable plugins.

    6.U will c CFW update enabler. That I am not sure how this function.

    Guys you will enjoy the Eye candy of this 6.20Pro-B5 CFW. I like these. It was release on 20 April 2011.
    My PSP is 3006 Brite v3.0 was OFW6.20-> CFW6.20TN-D->CFW6.20TN-D Permanent Patch->OFW6.20->CFW6.20Pro-B4-> Now CFW6.20Pro-B5 just an hour go.

    Thanks to the Greatest Creator.

    Greetings brothers,

    Ei guys i have seen this update but I am anxious to try it. I want to ask if this will work on a psp 3000 with a TA-090 v2 motherboard???? please replay because I don’t want to brick my psp.

    • The_Dcotor

      First of all, just use PRO B5, been out for a while. And if you follow the process exactly, if it crashes after doing the test with Perma Patch(x twice), IT IS NOT COMPATIBLE! other than that, it works perfectly on mine, which is also 3g.

    • Navin

      hey bro it will works well, Mine TA -093 v3, PSP 3000 4g so just try the proupdate first the the perm patch if ur proupdate is fail then don’t proceed to permanent patch. Good Luck

    Ei Guys I have Just installed the 6.35 PRO-B5 but the firmware sill got gone when it is put to full shutdown.. how can I fix this?

  • JustAcommenter

    Nice, just downgraded from 6.35 to 6.20, then used that homebrew enabler via patapon 2 savegame exploit to install this CFW. Everything worked out just fine and now my PSPgo can finally take over for my old fat psp which died after serving well for several years.

    NealTA90: You have to apply the permanent patch for the CFW, otherwise your PSP will always boot back into the original firmware after full shutdown…
