Have PSP 3000 with 6.20 Pro-B9 Perma that is in semi bricked state. Tried using the app by punker69 to fix a semi bricked psp but when trying to install the update it gives the " error 80010018 cannot read memory stick....". Have an official Sony MS and reads fine on my other psp. Also downloaded the update from different site just in case it was the OFW. Read on another thread that restoring settings did the trick but cannot go to XMB to restore settings. Any suggestions?
