My psp was bricked for sometime I the unbricked it by making a magic memory stick with rains memory stick maker and buying a pandora battery.

I looked through a couple of guides on how to unbrick my psp and I got one of them to work and I unbricked my psp.

But after it was unbricked I could only turn it on with a pandora battery I have looked for a solution but havent found anything.
I have two normal psp batterys and none of them work there was one time a couple of days ago when I managed to turn the psp on twice with both of them but sadly it doesnt work anymore.
I dont think the psp is bricked since I have tried to unbrick it again but when i try to run the eboot.pbp file I get the error 80010002 error.

My psp's is a model 1003
Its system software is 5.550 GEN D-2
All help is appreciated and thank you to those who take there time to help me
