I'm trying to downgrade my ofw 6.00 slim obviously and I've only used the pandora battery once on the same PSP slim. I don't recall what I did then but while attempting to create the jigkick battery by following the guide i used before, I put the 1.50 eboot renamed UPDATE into the memstick and in the PSP XMB menu it doesn't show up as the update but instead as corrupted data. without that I'm not sure how to continue but I have already made both the jigkick memstick and battery before. I'm not sure If I still need to follow the same steps because my battery is still a pandora. I'm sure i just need to create the jigkick memstick again. I need help to proceed.
