Getting Encryption Back after enabling root
After I rooted I was completely unable to encrypt my phone. This is a pain, because I encryption is a big must. Whenever I would try to initiate the encryption process the android wireframe guy would appear for a second and then the screen would go black and unresponsive. Holding down the power button wouldn't do anything. The only way to reboot was for me to remove the battery and reboot. I found several posts about other phones where people were having the same issue, and I was eventually able to piece together a little how-to guide.
The trick for me was to combine several of these posts into something that works.
1.) Temporarily disable any SU software (Super SU etc)
2. ) Reboot phone into "Safe Mode":
Turn the phone off completely. Press and hold the power button until the screen comes on. As soon as the screen comes on release the power button and press/hold "volume down". Continue holding the volume down button until the phone is done booting. Once the boot process is complete there should be a little "SAFE MODE" logo in the lower left hand corner of the screen.
3.) Make sure device is plugged in to charger
4.) Encrypt Device:
Do NOT SELECT "Fast Encryption"
5.) Encrypt phone:
Once you start encrypting the phone it will immediately restart the phone and then the android wireframe logo should appear and a progress indicator will also be present.
PS, for some reason this makes SuperSU non functional.
