Pro CFW B4 – unleash the full power of your psp (genesis compo entry)
Coldbird and Virtuous Flame announced a while ago that the next version of their CFW would be part of the genesis competition, and here they are, with CFW Pro B4, a new version packed with features.
One of the things that will probably get the most attention is that CFW Pro is now compatible not only with Firmware 6.35, but also with firmware 6.20 (separate download), a feature that was announced as a “big surprise” in an interview here on wololo.net. Not only that, but the 6.20 package actually has 2 versions, one being a regular HEN/LCFW, the other one being a permanent CFW (Permanent patch is not possible on 6.35 for now). This gives even more choice to all the people who were staying on 6.20 to benefit from TN’s Hen. It is now possible to use both TN’s Hen or CFW PRo on 6.20. A way for the two coders to let you try their work, and decide if you want to upgrade to 6.35.
There’s lots of stuff to be said about this new update, but I’ll simply quote Coldbird here:
Sony has always been trying to put a lock on our consoles, preventing us from using the full abilities of the devices we bought, well… if something’s locked then you just need the key, right?

- 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.

Download
CFW Pro B4 for Firmware 6.35 can be downloaded on Coldbird’s homepage here (or alternate link here)
CFW Pro B4 for Firmware 6.20 can also be downloaded on Coldbird’s homepage (or alternate link here). This version contains both the regular LCFW as well as the “permanent patch” version. I personally haven’t tried the Permanent version, and I do not recommend it unless proven that it really has benefits over the LCFW version.
There are lots of things to be said about this new release, I’m sure many of you will be testing and enjoying it, so feel free to give your feedback in this entry’s official thread here
i cant seem to get game catagories to work any more…. i wanted to play multi disc game like legend of dragoon, any advice? thanks in advance
Now the PSP3D works fine here!!!With some little problems like as Lag, but works…PSP 3001 6.35 PRO-B4 no fast recovery cause its fine that way…
Pra quem não entendeu nada, pode ficar pior, o plugin PSP3D.prx agora esta funcionando suave no PSP 3001 versão 6.35 PRO-B4, sem o fast recovery, funfando perfeitamente assim desta forma!!! Thanks!!!Obrigado!!!Gracias!!!Mercy!!!
i cant even get the prx to show up in plugins on recovery menu
Do i have to uninstall LCFW/HEN from my PSP before i launch TN Hen or can i run TN Hen even after PRO B4 has flashed LCFW files? Will something happen like brick if i run TN Hen without uninstalling the PRO B4 flashed files?
If you’re using the PRO-B temp version accoiding to another member here you can run TN Hen without uninstalling….. just as long as you boot into OFW first.
I tried running TN-D with the perm version(booted into OFW by holding select first) and instead of booting TN-D it just booted back into PRO-B4
Thanx a lot 🙂
I just needed a confirmation that i can safely boot tn hen…..
TN Hen boots from OFW even though the Pro B4 LCFW flashed files are still there in flash0
Thanks a bunch, Wololo!
the isos are loaded in the “uncategorized” section if you have game categories light and i don’t like it much…
i’ll keep both tn hen and this on my psp for now
Hey guys! Thank you so much for Pro CFW B4! What can I do with an old PSX backup .bin? Must it be converted to launch from xmb?
any one know the procedure of duel bootting??
*i mean booting
See 6.35 PRo-B4 and 6.20 PRo-B4 here: http://www.youtube.com/watch?v=8MBPMY5es_Y&lc=Vf4ANlCDCyLvmcHO7EqZtS46NsVKN9OIDI0kHoJJxJU&feature=inbox
thanks vf and coldbird, this awsome, and thank you wolololo for posting this.
i noticed somthing weird when using the mp3player plugin though, when i have it in seplugins and go to plugins from recovery mode, none of my other plugins show up
Great CFW. Amazing work. But something at me if just nagging and keeping me on TN D.
TN better step his game up. It wouldn’t be fair to call this PRO a ”game changer”, it’s more like a ”gamer destroyer.”
i have 5.50gen-b(full)
AND I AM NOT ABLE TO install 6.20 official
please help
what should i do?
its your version.txt in your flash0 replace version 9.99 to somthing lower….
This is fantastic news! I love being able to choose. I personally like the non-permanent version. Plus, I checked one Multi-Disc PSX EBOOT(Colony Wars) and it loads up and plays. Plus a few other PSX games work that didn’t. Thank you CB and VF!
I have a backup of an PSX game in the .bin format. Must it be converted to an eboot to run on psp?
I admit I haven’t tried to run a PSX ISO but I believe the required format is EBOOT.
I tried Balder’s Gate Multi-Disc Eboot and it works so far with disc swapping from the menu.
@wololo or anyone who might know,
i just got pro b-4 permanent the other day, im looking into custom themes, can themes mess up my psp 3000 4g?
thanks in advace
lol at a year ago no one think this stuff possible. No the psp scene not dead. Is more alive than ever. Thnks to people like wololo . Total noob. moskito. V flame . Coldbird and many others. Greets from portugal
there is a bug where when u pause a game (Psp Go) the pause will be there but when u delete it and turn off ur psp go and turn it back on its back there
I was in the 6.35pro-B3 ann me back to the 6.20 pro permanent works great! thanks coldbird and wololo!! Now I want the 3.56 CFW for my ps3!! >,,< Greetings from Mexico 😀
I seem to always be late to the “Party”, and did not know about any of this stuff before I updated.
is it possible to put a custom gameboot on my psp with this cfw?
yeah it is..I actually just changed a gameboot on the alienware theme to cloud’s geostigma attack.
google CTFtool_GUI v4.4
its pretty simple to use.
@anyone,
how do i get cwcheats to work for ps1 games?
it works for my psp games but not ps1..
Why is my psp not charging when i installed this? It only turns on when i connect it to its adapter.
I found a bug with 6.20 pro b4 perma.
when i try and use my psp camera (which i got from the eyepet game) It freeze’s and then turns off.
where can i report this? (unless its too late due to pro b5 coming out soon)
why works the 6.20 PRO only with 1G-5G ?? Is it not stupid
07g/09g are not compatible with 6.20. I would assume some drivers are missing. Ask that to Sony, not to the scene devs…
