I had updated to downgrade earlier. Then like a good little sony-pawn I updated on accident to 1.52

So then the brew stuff didn't work. Ok I thought, I'll just update and downdate again. WRONG!

I've been trying to use this bloody thing to downgrade, I know it worked earlier. I've done this thing about 500 times now. and its not giving me ANY red screen. Just freezes, then turns off the PSP. I don't have GTA:LCS and I can't rent it... I have no other way to do this. I need someone who is more computer/PSP-oriented than I am.

I have AIM and MSN and Yahoo, all under "TheMuffinKing340"
If you want to send help more live than this forum, that'd be great! You all rock, keep up the good stuff!

well if u updated to 2.71 u need to use the 2.71 downgrader u can't use the 2.0 downgrader...u just keep trying til u get a red screen, took me about 16-22 tries then i said a prayer and i got a red screen and no brick and a nicely downgrader 1.5 the i went and ran the 1.5>1.0 downgrader then upgraded back to 1.5 with a "clean" 1.5 fw since the 2.5-2.71 downgraders didn't give me a clean 1.5 fw dump

i used the same downgrader and it hit on try number 2. i never got around to going down to 1.0 and back up for a "clean" firmware and ive not had any problems with my psp.

yea that whole clean version that u have to go to 1.0 then 1.5 sounds like a myth to me cuz I never did it and I haven't had any problems either hallsguitar

there have been partial bricks cuz of cfw and the "tainted" fw the 2.5/2.6 downgraders give u, u can also upgrade to 2.0 and use the MPH downgrader for 2.0 to obtain a clean fw dump since all it does it trick ur psp to think it's 1.0 so u could upgrade to 1.5

I agree always good to go up to 2.0 then back down to 1.50

That's what I did too.
BTW, why did you carry on upgrading all the way to 2.71. If I remember correctly, and I think I do. You cannot upgrade from 1.52 to 2.71 in one jump. You have to go via 2.0+.

use a fresh formatted 32mb (the crappy free one) stick for the 2.71 tiff downgrader. i tried it on a 512mb and was there for like an hour before i realised to try a small memory stick and believe it or not, it worked 1st time!

Try restoring factory settings then format memory stick then try it
