PSP2-batteryFixer
-
A small utility that fixes most of PSVita's battery-related problems.
It deletes all the temp flags from the battery chip and hard-resets all devices.
This tool was tested on firmwares 3.52 - 3.74.
-
Usage
- Install the VPK with VitaShell
- Start the batteryFixer app
- Follow the instructions displayed on your Vita screen.
- If you don't see any text, and your vita doesn't power off after 5 seconds, press START.

How this works
This tool resets the battery controller (Abby) and reboots the system controller (Ernie) before Abby can get its calibration data. This in turn causes Ernie to do a full power cycle of all devices on Ernie startup due to bad Abby data, it also clears all the Abby calibration data and flags.
The PS+SELECT+LT+PWR+START for 10-15 secs key combination reboots Ernie and makes it do a full power cycle of all devices on startup, including Abby, but it does NOT clear its calibration data.
