Custom Firmware 6.39/6.35/6.20 PRO-B7 Released


The PRO team has released an official update to their custom firmwares. For those of you using the nightly builds you should definitely move on to this official release as it’s sure to be much more stable, plus it’s got tons of improvements. This custom firmware is for all PSP’s and has the new memory speed up feature that is very similar to Dark_ALex’s old MS speed hack, which helps improve read rates.

To clear things up, some unofficial builds have incorrectly been referred to as “PRO-B7″ This build is the OFFICIAL PRO-B7 release, straight from the developers themselves. Sorry for the confusion in the past.

Anyway, here is the changelog for the official PRO-B7 build:

[!] Fixed NODRM Engine (DDF012 DLC Costume Bug)
[!] Improved Inferno Game Compatiblity (GTA China Town, Corda2f, etc.)
[!] Updated scePower_driver NID Resolver
[!] Added Configuration Reset on PRO Update
[!] Added DA psp-packed user module support
[+] Added UMD VIDEO / GAME XMB Mount Feature (No UMD required, allows for Game Updates)
[+] Added Custom IPL Flasher for 6.39 PRO (1g, 2g hackable mainboard permaflash)
[+] Added non latin1 ISO filename support
[+] Added memory stick speedup option
[+] Added ISO cache option (available in Inferno and NP9660)

As stated before, if you’ve been keeping up with the nightly builds then this release should include many improvements. A big hanks to all the developers who contribute to this project, including Coldbird, VirtuousFlame, neur0n, and anyone else I’ve missed. Keep up the great work guys!

      Firstly which one are you using? 6.20, 35 or 39? Try and change ISO modes and/or delete the plugins to check if the problem’s related to one of the plugins; by the way, if it doesn’t work out for you, there’s PRO-B8 out now.

    I am currently in PRO-B5 (Not Permanent) How can I update my PSP to PRO-B7 without bricking my psp…. I don’t know how to uninstall a custom firmware :c

  3. NeW 1 says:

    Put the PRO-B5 permanent patch – which is the same file that you used to install PRO-B5 in the first place – and run that. This will automatically uninstall it.
