check your PSP if you have a plugins that was enabled, this might give you an error!!.. so just disable your plugins or format you MS!!, and then report back!
I had actually formatted my MS before trying to use the program and I have no idea how to check if I have plugins or not.
I also have a pandora battery available if that could be a solution to try.
<p>after all this process end greatly and i can use my psp like others,can i put out the battery??</p>
<p>I have downgrade my psp to 3.71 last time. Last week I use my friend memory stick and accidentally update it to 5.03. Now my psp cannot read my game. I have installed the hellcat's recovery and 3.71 firmware into game/recovery menu but its still cannot read the recovery icon and said "corrupted". I tried to change the setting to read m33 memory card but once I push select button nothing happen and I also tried push "R" button during restart and still nothing happen. Please help me about this...</p>
