I have a Japanese PSP classic (phat?) that came with 3.03 OE-B preinstalled. For a year-and-a-half, I was happy with this firmware version and saw no need to upgrade. Then along came Patapon, a game which required fw > 3.7X. So with the help of some excellent guides here at QJ, I was able to both successfully(?) create a Pandora battery & "magic" stick and make the initial upgrade to 3.52 M33-4.
At this point, I became somewhat confused as one guide recommended that I first upgrade to 3.71 M33-4 before finishing up with 3.90 M33-2, while another guide stated that 3.71 could be skipped altogether. I chose the cautious route and tried to upgrade to 3.71, as this is my first time tinkering with my PSP. Alas, I must have done something wrong when running the 3.71 M33 update as the following error message appeared:
"The system configuration of this PSP system does not appear to be correct.
The update cannot be completed.
Contact technical support for assistance.
Then the PSP bricked after pressing the (x) back button. :Cry:
Thankfully, I had created the Pandora battery using this guide before my fw upgrade attempts: http://forums.qj.net/f-psp-pandora-d...ry-124530.html
When holding down the L-shoulder button while powering on after inserting the pandora batt., the "Extended Pandora (Pre)Boot Menu" appeared. It's at this point that I'm lost. I've tried searching with no success for a guide to help me; perhaps I'm not using the right keywords?
I've tried "booting to full firmware (from memstick)" and it does load up into fw 1.50, but the guide mentioned that this is only a limited version. After shutting down the PSP and replacing the Pandora with a regular batt/memstick, the PSP remains bricked.
The "Go to Pandora mainmenu" selection doesn't work; it just blanks out and hangs.
What steps should I take in order to fully unbrick my PSP and restore it back to (at least) 3.52 M33 again?
Please, any help would be greatly appreciated! Thanks.
