View Full Version : Problems Downgrading

June 8th, 2007, 01:05
I have a PSP with a 2.71FW and it's also a TA-082 unit, I was able to read both numbers. I'm trying to downgrade it to play emulators.

I have used two different downgraders
1. TA-082 downgrader by Dark-Alex (Hend).
2. 2.71 ta-082 ta-086 downgrader with (1.5 Enabler).

I always get one of two error messages.
1. Error Decrypting DATA.PSP
2. Extracting Prxs. Wrong PDP File.
Then it restarts.

Did I miss a step. I have read the guides to the letter. Please help me out

Have you tried re-downloading the official updates? They might be corrupted.

I downloaded the EBoot file from several places several times, the size is 13.2MB or 13,575 KB. The Path of the file on the PSP is L:\PSP\GAME\UPDATE\UPDATE.PBP

Honestly I have no idea what you could be doing wrong. I've never seen this error before and I've downgraded more Psp's than i can remember.

If all else fails you can update to 2.80 and use the 2.80 downgrader by the noobz team. Its just as safe. It works basically the same way.

Is 1.50 Firmware samething as 1.50 UPDATE?

Some of the downgrades come with a SRC Folder, where to put that folder?

Yes they are the same thing.

And thats the source code.

Thanks I fixed the problem, it was with computer transfering the file to the psp.
