PLEASE HELP FAST! PSP BRICK! i'm newbie

OK. I never had so bad day in my life.
I tried to install Applecore on my 3.71 M33-4 with 1.50 kernel addon PSP. I did everything exactly like on this tutorial:

I didn't backup my flash0 but on YouTube someone send me the backup file - in this video.

I did everything like in Applecore tutorial, and I turn on my PSP and XMB looks weird. So I use backup of flash0, I copied it to flash0. (Of course in Recovery Menu.) When it finished, I unplugged USB cable, then I press Exit. Now I turn on my PSP and what?!

Screen is black! Any key presses won't work! :eek:

I tried accessing Recovery Mode (hold R while startup) but that didn't work either so it must be full brick.

Is there any way to save my PSP?! :(

I can't afford to buy another one at the moment
And I need it fixed FAST! Please help.

if you know someone with a homebrew capable psp zou could ask him to make a pandora battery

that's it! yes! pandora bat!

but what do you mean? how the heck I could use pandora on psp where xmb or recovery doesn't work?!

thats because when i was downloading the flash0 files from the link on youtube, he doesn't had 1.50 kernel addon v2, and i had. so maybe thats why applying the backup only screwed up even more.

by the way if you need this information, my psp memory stick capacity is 4GB, but I got psx, psp and a lot of homebrew on it that I had only about 40meg left :(

so of course i'll have to delete something, but how i can if i cant connect to usb without xmb or recovery, and you know, my memory stick is not to put directly to usb port like some others.

Pandora's battery is the only way and you will require another PSP that can run homebrew just search for Pandora on this site.

I don't have another PSP. and i cant afford to buy another one (at least at the moment).

but my friend made psp battery as pandora battery for me. what do i do now?

i hope you will tell me how to downgrade if needed. but i dont know how to because i bought my psp from ebay, with already installed 3.71 m33, so i never had to deal with downgrader or anything.

if your interested datel made a tool battery i bought it worked also they just made this product too(http://us.codejunkies.com/Products/P..._EF000530.aspx)
this thing converts your battery without the use of a psp an also converts it back to normal

You don't need to downgrade just download Despertar del Cementerio from here and follow the readme if you have a pandora's battery.

My friend made a pandora battery. and magic memory stick from the 2gb one. he put it in my psp, then it turns on and i see a black screen.

and for NoQuarter - I found that "Despertar del Cementerio" but do I click Version 1, 2, 3 or 4? I'm having firmware 3.71 m33-4 with 1.50 kernel addon.

But i think nobody understands. I had 3.71 m33-4 with 1.50 kernel addon, and i wanted to get back to original xmb (i installed applecore using cxmb) so i downloaded the backup but didnt know its for 3.71 m33-4 WITHOUT 1.50 kernel addon so it bricked all my flash0 files.

I'll try to find somebody who I'll send my PSP to and he unbricks it for me.

Get your friend to make the upms which you can get from here - www.upms-project.com If this dont work then you might have corrupted your nand beyond repair or you may be using a fake memstick which pandora wont run on to well try rewriting the stick and then try a different stick if you can just to be sure.

Download Pandora's GUI it'll save you both time :)
