I'm gonna do a little tutorial to Install TWRP and root on Leeco X820....just received yesterday.
First we gonna need the official ROM 14S from here:
And the Pack that i prepared here:
Step 1: Unzip the file twrp+root.rar and Put the file BETA-SuperSU-v2.72-20160510112018.zip on the internal memory,
put LE_X2_X820-CN-FN-FEXCNFN5601405103S-5.6.014S.zip file on the internal memory too (this 2 files)
Step 2: Power off the phone
step 3: Enter to Fastboot mode (turn on pressing volume down)(http://www.netded.com/uploads/allimg...14151201_1.png)
Step 4: on the folder that you created to unzip (example C:/twrp+root) press and hold SHIFT then right mouse click and go to "open command line window here" (or something like that in english)
step5: Connect your phone and wait to install the drivers
step6: on the command line write: "fastboot oem unlock"
step7: If that's ok then write: "fastboot flash recovery Le_X820_TWRP.img"
step8: If that's ok now you have the recovery twrp (chinese) installed (if this not work 1st time, do it again)
setp9: Reboot your phone on recovery mode (holding power button + volume up) (from fastboot, you don't reboot in normal mode)
step10: you gonna see the recovery in chinese, but don't worry, this recovery is the same that always and the options are on the same order: http://www.teamsuperluminal.org/wp-c...02/twrp3_4.png
step11: go to install and flash the 14S rom (if you want), and if you want to keep your rom (probably 13S) just flash the SuperSU beta file.
If you want to Install a clean rom 14S with google play support (recomended), you have to wipe, then Flash the ROM 14s, and then flash this GAPPS (working fine) http://opengapps.org/ (just choose download ARM64+Android 6.0+ Pico version) and then flash the SuperSU beta file provided.
If you want to change the Language (in my case spanish), you can always use Morelocale (from playstore) with Root privileges
