First try to remove all power sources and the Memory stick from the PSP
then put in your normal battery in and try to start.
If thatdoes not solve the problem i do hope that you saved your original NAND dump.
Re-flash it to your PSP. your PSP should start like before. if not... you are in trouble

(
Make shure you have no Themes activated, set your PSP's settings to 'default'.
Then try again.
If you encounter the same problem try to re-build your Magic-Memorystick with the latest
version of Despertar del cementerio from Dark_Alex.
good luck!

Hi and good morning

So, lets do this ^^
i have slept about it and came up with a few thoughts.
first, when you start the PSP hold the right shoulder trigger.
You should boot into the Custom firmware Recovery menu.
If not its worse then i hoped and you can ignore most of this answer.

With 'Toggle USB' you should be able to activate the USB connection and to access the Memorystick.
But leave that alone for now.
Go to 'Advanced', here you can toggle the different flash drives of your PSP to access them via USB.
Handle that possibility with extreme caution if you dont know what you are doing!The PSP stores personal settings and themes in Flash1. Most of the time here lies the cause of boot errors after flashing a firmware.
Chose 'Format flash1 and reset settings'. that resets your PSP to the default settings.
After you exit the Recovery menu you should boot normal or get a blue screen with an error mesage in many languages. Press CIRCLE if you see that screen.
After that it should boot normal and can configure the PSP again to your liking.
If not... you need to re- flash the PSP.
Try it first with the original set i hope you still have.
Else create a new one with Despertar del Cementerio v7 from this page
http://alek.dark-alex.org/filez/dax/ (Dark_Alex (the maker of this CFW) official page)
read the included instructions to learn what else you need and how to do it.
If you have no access to a homebrew capable psp... you are screwed
but you can still search the interweb for programs to bild the magic Memorystick without a PSP
that is possible but in a grey to dark zone we here dont want to go.
If you have no longer hold of a Pandora battery you are 'realy' screwed and
need to default to a bought service tool battery or a hardmod wich i both cant reccomend.
I realy hope the first passage solves your problem!
