PSP Firmware 2.80 Downgrader Released

[Mooney]

Using the 2.80 Kernel mode exploit found by Team C+D, 0okm has created a downgrader for firmware 2.80. This app will ONLY work with TA-079~081 motherboards. This process is quite tricky, so make sure you understand what you're doing BEFORE you try downgrading. Here are 0okm's instructions:

HowTo

1. Run moonlight's "FW2.60 DownDate helper" on FW1.50PSP to Dump "FW1.50 File"

　　or Download "FW1.50 File" from psp-hacks downdater_final.rar

　　Extract downdater_final.rar\DOWNDATER\ all file to ms0:\DOWNDATER\

 

2. Run FW150IPL_Dumper on FW1.50PSP to Dump ms0:\DOWNDATER\PRX\FW150_ipl.bin

　　NOTE: if no FW150_ipl.bin in ms0:\DOWNDATER\PRX\

　　Run FW280DownDate4TA-079 will brick your PSP !!!

 

3. Run FW280DownDate4TA-079 By xLoader

　　NOTE: Don't use eLoader to Run FW280DownDate4TA-079

　　it will brick your PSP !!!

NOTE: 0okm is not responsible for any effects this app may have on your PSP. As with all downgraders, there is a risk it will brick your PSP. USE AT YOUR OWN RISK!

what the hell? So put the firmware file in the folder, run dumper, then run the downdate thing?

Yeah... I think it goes like this: (Please do not rely on my instructions, as I am not too clear on 0okm's instructions either. )

1. Download the "2.60 DownDate helper" and put the "FW1.50 File" it includes into X:\DOWNDATER\ (X is your PSP's drive letter)

2. Run the FW150IPL_Dumper tool to dump "FW150_ipl.bin" into X:\DOWNDATER\PRX\ (NOTE: If you do not have "FW150_ipl.bin" in X:\DOWNDATER\PRX\, proceeding to step 3 will brick your PSP!)

3. Use xLoader to run the FW280DownDate4TA-079 app (NOTE: You must NOT use eLoader to load the app or it will brick your PSP! You MUST use xLoader!).

I hope these instructions clear things up, as English doesn't seem to be 0okm's first language. Hope it works for anyone who tries it!

I've been reading elsewhere, it seems this downgrader is extremely risky! Be careful..

There's a couple installers on other sites. They are supposed to be safer. Damn, still no love for the ta-082 though.
