2.80 to 2.71 Downgrader for TA-079 through TA-086 PSPs
Earlier today 0okm announced that he has created a 2.80 to 2.71 downgrader that is compatible with TA-079, TA-082, and TA-086 PSPs. What this means is that those of you that have 2.80 on TA-082 PSPs can downgrade to 2.71, then to 1.50 using Dark_Alex's TA-082 downgrader. Once at 1.50, TA-082 PSPs can upgrade to the 3.02 OE-B custom firmware. While this is exciting news, 0okm has decided against a public release and has asked that requests for the downgrader should be sent to him via email. I haven't has a chance yet to test this myself but I am waiting for a copy of it as of the time of this post.
You may
email 0okm yourself to obtain the downgrader but as always
be aware that firmware modifications can permanently damage your PSP beyond repair and render it completely unusable. If you do choose to try the downgrader then you use it at your own risk. I will post as soon as I am able to test the downgrader myself and share what the results are.
Should you be brave enough to try this yourself you'll need:
In order to downgrade you will need to follow these steps:
- Open the 2.71 Update EBOOT in PBP Unpacker
- Extract the DATA.PSAR file to a desired location on your PC, and move it to the root of the Memory Stick of a PSP with one of the following:
- FW 1.50\
- FW 2.71 with HEN-D
- Custom FW 2.71 SE
- Custom FW 3.02 OE PSP
- Extract and run PSARDumper on the PSP mentioned in step 2.
- Press circle in PSARDumper to dump without sigcheck and dump reboot.bin.
- Once DATA.PSAR has been dumped to the Memory Stick, move the files to the PSP to be downgraded.
- Run 0okm's downgrader using xLoader.
