- Updated charging rate.
- De-activated Micro SD upgrade method.

- Several USB-OTG optimizations.

Additional Notes:
- Market compatibility is still not stable and not all applications are accessible.

- Before upgrading to this version, remove your MicroSD to protect its contents from getting formatted.
- Once Recovery finishes formatting data, cache, and dalvik, you may safely insert your Micro SD after reboot.
- The upgrade process will take longer than usual. This is normal as re-partitioning NAND takes time.
