Downgrader Test for 2.50/2.60 by Dark_AleX
With the help of yoshihiro and mathieulh from SXT
We thanks everyone who bricked their psp in the past while testing the older revisions of this software
This is a WORKING downgrader see http://alex.lan.st/downdater.mp4
This software is free , and i'm not responsable if it causes damages to your psp.
If you use this software, you agree that you are using this program at your own risk and that you won't blame the author for that.
"Someone told me that a downgrader for 2.50/2.60 was impossible. How does this work?"
This one uses another more risked technique (and i repeat: untested) than the mph downgrader.
It uses some sony libraries found in the 1.50 updater to perform the most critical steps, the logical format of the flash, and the ipl writing. See technical details for more info about how it works.
This software requires that someone with a 1.50 runs a little program and send you the output so you can init the downdate process. (by legal reasons i cannot provide those files directly, that's why this is needed).
The 1.50 program is TOTALLY safe, it only dumps the flash of a 1.50 user and it also extracts some special prx's found in the 1.50 updater.
Technical details
------------------
This program performs the following operations.
- It loads the ipl_update.prx and lflash_fatfmt.prx from the 1.50 updater.
- It performs a logical format of the flash0 partition using the function
sceLflashFatfmtStartFatfm t found in the lflash_fatfmt.prx
- It writes a dump of the 1.50 flash0 to the flash0.
- It writes the Initial Program Loader (Ipl) using the functions sceIplUpdateClearIpl and sceIplUpdateSetIpl from the ipl_update.prx module. The ipl is embedded in that module.
Other considerations:
--------------------
- Users with TA-082 psp's shouldn try this. Also, it may be better that at the beginning, only users with a 2.50/2.60 NOT from factory (they updated from a below firmware) try this.
RELEASE NOTES : as I am posting this at 4AM in the morning Alex is asleep so the sources and changelog will be available when Dark_Alex will wish to.
At this time only the binary is available
This version also performs logging so be sure to have at least 16MB more on your memory stick before performing the downgrade.
THOUGH IM NOT CONDONING USING THIS its just a heads up on whats going on adn what the developers of this downgrader are saying
-i will not post the download of the downgrader here check it out at your own risk
