WHEN THE FLASH COMPLETES: (Takes about 2 seconds)
On phone, unplug the usb cable and power it off by taking out the battery and putting it back in.
BOOT INTO RECOVERY MODE FOR THE FIRST TIME
HOLD VOLUME DOWN + POWER until you see the LG logo and then temporarily release the POWER button, immediately pressing and holding it back down until you see the white prompt [factory reset] screen.
Use the hard keys to select "YES" and then "YES" again to boot into TWRP
Notice: After the TWRP splash screen you will see the option to type in the password to decrypt the filesystem just ignore it and press the cancel button.
How to Disable encryption and flash SuperSU [Root Your Device]:
1. In TWRP, go to Wipe > Format Data. Enter the keyword ‘yes‘, in the provided space and enter. This will wipe the automatically encrypted filesystem, and decrypt it.
2. Once the wiping is done, reboot back into recovery. Go to Reboot > Recovery.
3. When the recovery boots again, connect your phone to the PC and Enable MTP under the Mount section.
4. Transfer the downloaded ‘no-verity-opt-encrypt-**.zip’ and ‘SR1-SuperSU-v2.78-SR1-20160915123031.zip to your internal storage or EXTSD
5. Disconnect the device now.
6. Tap on Install. Now, navigate your phone’s storage and select ‘no-verity-opt-encrypt-**.zip’. Finally swipe the ‘Swipe to confirm Flash’ button on the bottom of the screen.
7. The flashing process will merely take a few seconds. And when it’s done, follow the same method to flash the root package – SR1-SuperSU-v2.78-SR1-20160915123031.zip
Wait 1 or 2 minutes after the zip files are done flashing then reboot system and PROFIT! Your phone may take 3-5 minutes to boot the first time and it might boot-loop once or twice at the Metro PCS splash screen but don’t worry this is expected.
