So, my friend went to my house this morning with his 3.52 m33 PSP for me to upgrade it to 3.71 with all the addons and to install ir shell. Everything was alright till we went to play via wireless. The games were not loading. I figured out that the problem was the plugin that makes ir shell start instead of the xmb.
After some minutes my friend's psp started acting crazy. He was in ir shell and the 'Exit ir shell' window was always appearing. When he loads a game, it is like he was pressing the down arrow (I don't know if there is another button that it's ****ed up). I noticed that this only happens with games(umd, homebrew).
I used pandora to downgrade his psp and do all the process to 3.71 m33 and addons, but the problem still persists. If anyone knows the solution it'll do my day.
Thanks in advance,
EDIT: It's not the arrow key. It's the down on the analog nub.
