1.50 Downgrader for 2.50/2.60 PSPs Released

Posted by ryuzaki0 on from the now-you-can-play-real-games-on-the-psp dept.

Cyraan writes "PSP owners rejoice! Hot on the heels of the recent exploit discovery & bricking that resulted from early test versions comes a confirmed working downgrader. The method uses a GTA eLoader that will turn any version 2.50/2.60 PSP, with the exception of those with a TA-082 motherboard (how to check without opening/voiding warranty), into a version 1.50 capable of playing all forms of homebrew. One thing that may not be mentioned specifically in the article: it is recommended you NOT use the 32mb Memory Stick that came with the PSP, as the process creates alot of log files that can fill it up, possibly causing a brick."

    Actually, the ISO is out and runs just fine on 1.50 using devhook 0.41d.

    Out of appx 500 posts on success/failure of the downgrader, only one had failed and bricked his PSP. So yeah unless YOU do something wrong, it's almost not possible.

    1.5 Didn't have the web browser that the later versions have. There are some other things too, like I think Sony added an RSS readers.

    In this case, it is a downgrade.

    Anyone interested in what software is available for the GP2X should look here: http://www.gp32x.com/

    There are plenty of emulators, freeware games and utilities. There is also stuff for the previous-generation GP32.

      You're looking in the GP32 (the previous model) section. The GP2X has superior (and built-in) mp3 and video support, is much faster - it has two processors, each of which is twice as fast as the old model's CPU. My GP32 can play Phantasy Star 4 (Sega Genesis) and a bunch of Turbographix games flawlessly, among other things. Apparently the GP2X has excellent emulators for Genesis/TG16/SNES, though can't say for sure since I haven't received my GP2X yet. :) But since it has considerably better hardware, it seems reasonable. The only emulation that is supposed to be buggy and slow on the GP2X seems to be PSX (because of the 3D) and DOS emulation.

    Not really. DEVHOOK makes it almost trivial to use the 2.0/2.5 firmware features from 1.5, and only adds maybe 10 seconds to the time it takes to get things up and going.

    Going back to 1.5 doesn't mean you lose all those features anymore.

    Note that the program was on beta 5-- the previous four test versions bricked PSPs, period. They were outputting a whole lot of debug data about each stage of the flash, it seems, since there are some complex steps to get things to the right point. It's not just writing bytes-- this downgrader apparently actually borrows chunks from the official PSP updater and does some interesting tricks to bypass various protection mechanisms.

    The logs were there purely to figure out where things went wrong; nobody expected this version to work.

    But some of us actually enjoy expanding this cool little device with things like audio/video streaming (PSPRadio,Pimpstreamer), using the psp a universal remote (iR Shell, iTunesremote, PSPVNC), reading other media file formats than those allowed by Sony (PMP Mod, PSP Media Player). Check the full list here : http://psp-homebrew.eu/listall.php?filter=category
    Oh and we still purchase games for it too (but no way am I buying a UMD movie ...)
