How do I downgrade PSP firmware 2.71?

March 14, 2007 3:58 PM

Does anyone have clear instructions on how to downgrade PSP firmware from 2.71?

I have always been irritated with my PSPs inability to run any homebrew, but it seemed fairly risky to downgrade the firmware. Now it looks like there are some safer options, but all the instructions I have found are a bit convoluted or translated from some other language making them a bit off. Do I still need a copy of GTA to downgrade (no one mentions it, but maybe it's just assumed at this point, I don't have one)? The PSP I have is not a TA-082, if that still matters. There must be someone out there skilled as both a hacker and a decent writer who can set this down to help others who are confused.

Best answer: have you seen this? a super quick scan shows that some people do mention some problems in that thread, but I didn't look further to see if they found any resolution.

You don't need GTA, but you do need somebody with a PSP 1.50 (or some other access to the 1.50 firmware.)

Response by poster: Juv3nal - thanks, those are better than most the instructions I found. I'll try walking through them and see how it goes.

Rhomboid, according to juv3nal's links "Now the 1.50 firmware dump becomes useless". This is some of the problems I was having with the documentation. I think the process is easier now than when your statement was true.
