My psp does not turn on.

I was on firmware 3.71 M33 (along with 1.50 kernel) for a few days but later I decided to go back to 3.52 because IR Shell didnt work on 3.71. I ran the 3.52 M33 update and succesfully flashed my psp. When the flashing process succesfully ended I pressed x to shut down as asked. Then when I tried to boot the psp never turned on. The green power light stays for exactly 30 seconds and then goes off.
People please help. What could have gone wrong? Hope you could find a solution to this mess?
Thanks in advance

theres 2 solutions to fixing your psp. I had this happen to me before psp green light turn on but no screen.

1. Try go to recovery menu Holding the R trigger when starting the psp

2. the pandora battery. it will unbrick it and bring you to 1.5.go to http://www.pspbrew.com/forum/viewtopic.php?t=9208 to make the pandora battery. if you dont have one you have make it on a friends psp or ebay

The first one failed I tried it the whole night. Will now try pandoras battery. Thanks.

do you have the pandora battery?

No I dont have one nor do I have any friends who own a psp. I am doomed.

buy one on ebay..or find someone on here who maybe lives close to you.

The only thing I can do is buy one on Ebay.

Heres what you do....

1. Turn off your psp
2. While turning on your psp hold the R trigger until you see a service looking screen pop up
3. Download this file... http://www.sendspace.com/file/k838d3
4. Toggle usb
5. run the program you just downloaded and follow its instructions

after everything is done you should be restored to 1.50

but didnt he say he couldnt get into recovery?

Not sure, you didnt really instruct him on what to do after he got into recovery so maybe he figured it would fix itself after he got there...just setting this out of the way so we'll know for sure.

try hitting the brightness button that may be your problem

try hitting the brightness button that may be your problem

Doubt that, cause he reported it goes to a black screen then shuts off after about 30 seconds or so...it's usually a sign of a semi-brick.

hmm yea then his only hope is pandora im guessing cause i just hacked 2 psps today and 1 had that brightness problem lol

I cant get into recovery mode. The LCD never lits up.

Alright, then your only option is pandoras battery...
