Hi.

I had version 2.0 and downgraded to 1.50 for like 3 years ago.
I havn't played for a while and i was going to do so, but when i tried
to, i got this error "The game could not be started (80010002)

I read something about recovery and i tried to hold down R while turn my PSP on to get it up, but nothing happend.

Im total noob with this, so if someone could help me out or have an guide with this version how to fix it, i would be pleased by that.

What were you trying to play when you got the error?Also 1.50 is an Official Firmware and has no Recovery Mode.

What you are going to need is a Pandora's battery and a magic memory stick.
Here's where you can get your Battery DealExtreme: $8.47 Pandora Service Mode Unbricker/Downgrader Battery for PSP 2000/Slim (1200mAh)
You can make the mem stick here is a tutorial Article Detail - PlayStation Portable News - PSP Updates
Then get 5.50 GEN-B or 5.00 m33.
To download, download and extract the folowing links, then place the UPDATE folder within them to your memory stick.
For M33 get this first PSP Downloads | Custom Firmware 5.00 M33
Then this PSP Downloads | Custom Firmware 5.00 M33-6 Update
For GEN B get this first PSP Downloads | Custom Firmware 5.50 GEN-A (Build 4)
