Hi, i have a PSP 1001 Ver. 5.01 i accidentally updated to that version.
and i want to downgrade it.

I tried ur method, but it seems like the memory card doesnt blink or anything. the screen just black.

You u think you can help me??

Thank you soo much!

you might have a corrupt magic memory stick or a bad pandora battery.

to check your pandora battery, take out the mem stick and the umd disc if you have one in there and your pandora battery.

when everything is out, put your pandora battery in but dont press anything.

if the psp's power light turns on automatically, but still leaving a black screen, you have made it correctly.

if not, try turning your PSP on manually, if it doesnt boot or even turn on your PSP, you have a corrupt battery you need a new one save some money and get a 2-in-1 pandora battery here: http://www.dealextreme.com/details.dx/sku.15153

if it boots to the main psp screen, try making your pandora battery again, then put it back into your psp when done, if the psp's power light turns on automatically, but still leaving a black screen, you have fixed it.

well, thats the battery, now the MMS,

ok, take everything out of your PSP ( battery ms and UMD disc if there is 1 )

now insert your MMS.

hold down the 'L' trigger button and insert your pandora battery.

wait until the screen shown below comes up


if it doesnt after 30 seconds, make your magic memory stick again, but when the program is running, dont use the computer.

when done, try doing step 3 of my guide again.....

hope this helped somehow...

if you have any more questions, just ask =D

I think that I ****ed my psp up somehow. I made a mmemstick and pandora and it didn't work, nothing came up, now when I put my origional battery in, it stays black

Uh-oh... Bricked.

how can I unbrickify it?

what ver PSP do you have? if its a slim with a TA 88v3 motherboard or PSP 3000, you cant currently...

use the links in the guide to find out if the PSP is a 88v3 motherboard....

if your PSP isnt a slim with a TA 88v3 motherboard or a 3000, it can be custom firmwared, if you still have a phat PSP with 1.50, you can update straight from 1.50 to CFW, go here on how to do it: http://forums.benheck.com/viewtopic.php?t=26563

lol, I have a phat psp, that's not the problem. I was wondering if I could make a mms in a bricked psp using the psp as a card reader? I think that may be the problem, I used my psp when it was bricked as a card reader.

no you cant, i had that same problem when i first bricked mine, i had to go a friends place to re make my MMS....

yep, I'm going to borrow my friends psp tonight hopefully I just had a corrupt mms.

It worked! Thank you!

thats good =D

if yer need any more help, just ask =D

Is it possible to make a pandora battery with a psp slim, and use the pandora battery with a phat psp?

thx!

Do you mean hardmod or softmod?

you can only softmod a phat battery in a Phat PSP and use that pandora battery on a phat PSP or a slim PSP.


a hardmodded slim pandora battery WILL NOT work in a Phat PSP, onla a slim PSP.

but a hardmodded phat pandora battery will work in a phat PSP and a slim PSP.

So answering your question: It is possible to make a pandora battery using a slim PSP, but the pandora battery that is made in the slim, it WILL NOT work in a Phat PSP. but done in a Phat PSP, it will work on both slim and phats...

Hope that helped...
