partly bricked psp

i just downgraded my wifes psp from 2.80 to 1.50 it worked perfectly until she asked me to put a custom theme using themepsp i did not think anything of it since i have used that same program on my psp but little did i know i needed to downgrade to 1.00 and then upgrade to sony 1.50 eboot so i run themepsp on my wifes psp and the screen goes white and the the system reboots to the blue screen of death and can not go back to the xmb but if i put a 1.50 game in it works fine i just cant get to the xmb can someone help me i have a few ideas but would like feed back to give me some more ideas so i can fix this any help would be appreciated

offtopic: i'm not sure if you should mention in your sig that you have all those UMD backups.

I never use theme PSP

so do you keep on getting BSOD

Have you tried updating

cant update the xmb id disabled that is my problem

There is nothing you could do.

Either take it back to the shop

Or

Send to Sony

Have you got a PSP or know anyone else with a PSP. Because you can get 3.02OE and get the recovery mode onto your MS and fix it with that. Even better if you have a Memory Card Reader you could just put the recovery folder on your MS yourself.

i will try the custom firmware i have never installed one b4 can you send me a link to a installer guide

there you are :)

3.02 easy installer with recovery mode

thanks for the help but i think recovery mode only work for custom firmware i tried and nothing happens for me thanks for the help

What happens when you click O ?

It restores settings

i know that but i was asking the dude because if you press O it should take you back to the xmb after reboot so what happens after you click O

it's starts to reboot and then goes back to the BSOD and it keeps trying to reload and it keeps going to the BSOD if i put in a 1.50 umd game it will load up and play just fine when i quit the game it's back to the BSOD i googled how to unbrick my psp iand read i can open it up and make the usb go straight to the flash and fix it from my pc

Sounds like a corrupt flash

i used the same themepsp that i used on my psp and it worked fine the one with the ps3 theme . i have upgraded my psp to 3.02oe how do i get back 1.50 i find it easier to work with

Just use the recovery menu

i tried to used the recovery it says to press R while the psp is on and when i do nothing happens i used the basic installer 1.50 off of my pc i am lost on what to do

Do a full hard reset on the PSP.And do you have the recovery folder installed.

Then load recovery menu

well i used the recovery install program is anything else i need to do besides that

Load the recovery menu then launch the eboot

sorry for the dumb question but how do i do that i cant seem to find out how to do that

Press R on start up

i press R on start up and nothing i have the recovery folder in ms\psp\game\

you need to do a hard reset on the PSP

i did i took out the battery and it still did not work

i just tried once more and still when i press R on start up nothing happens it just goes to the xmb

Try switching it on then wait about 7 secs then push R

it worked thank you so much you have been a lot of help tried the recovery on my wifes psp but nothing to all that helped me thank you have a merry x-mas splodger and waggster and all of you that help us noobs so many would be lost with out you and people like you

Merry Christmas to you as well.

wait how did he get recovery menu i thought he had 1.5....

He was returning to 1.50 on the other PSP, the one that was on 3.02 OE-A.
