Fixes for TWRP

Hi,

The battery percentage fix depends on this commit also - https://github.com/abcdjdj/android_bootable_recovery/commit/77d65af812ab859c38fdb3ebd2e720d665248837
Without the dependency commit, the battery status (charging or discharging) won't be shown (the '+' sign when charging in TWRP).

Regards,
