    This isn’t working for me. I am getting an error after going to recovery mode. I first get the red triangle with exclamation point. I then push volume up and power which gets me to a system recovery menu. I wipe cache partition and then select Apply update from sdcard. Then it gives me an error and reboots. I have double checked that the software is in the root directory and doesn’t have .zip.zip after naming convention. Any idea what I may be missing?

    Is this process reversible?

    • Make a nandroid backup in recovery and you can restore it if you want to revert back!
