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.

1. Install the VPK with VitaShell
2. Start the batteryFixer app
3. 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.

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.
