Hacking Autocursor bug after using PSP2-batteryFixer

[Fireminer]

I have a hacked 3.65 fat PSVita. This morning I installed PSP2-batteryFixer and used it normally. After the system rebooted, the cursor stared to scroll down automatically, whether I was in VitaShell or the Settings. Also, I couldn't run Homebrew Launcher. I tried to restore the system and then reinstalled VitaShell, and then even upgrade the firmware to 3.73 and then install h-encore2, but the problem persists, and I am sure that there is nothing wrong with the D-Pad. Now I can't even access ux0: because the cursor refuses to move in VitaShell. Does anyone here know what is wrong with my PSVita?
