Error when using downgrader
Hey all, I got a hold of a 2.81 PSP and I'm in the process of downgrading it to 1.50 using the 303 Hen downgrader. However, as I came to step 11 - "If it is showing up as HEN then go to the memory stick and run the x.yz update". When I ran this update, I got the message "Battery not 75%" and the program quit me to the XMB. I then turned off the PSP and charged it fully. When I turned it on again, I ran the x.yz updater and I get the message "The game could not be started. (80020148)". Looking up the error message on these forums, it described this code as PRX type unsupported - which didn't quite help me. So what should I do? My guess atm is to run the 303 FW again, and to repeat the process from step 5 (step 4 says to put the 303 eboot on the PSP and to run it). Thoughts?
Note: The steps come from the "Downgrader_HOWTO.txt " file of the downgrader folder.
