* FOLLOW LANG INSTRUCTIONS:

Install KingRoot 4.0.0.233 from pc by pressing *#0808# then pressing ptp + adb then ok
Use the mobomarket app to get kingroot on the phone. You fiqure it out but get that app on the phone.
Connect the phone to wifi and root phone (Everytime the phone reboots you will have to restart the wifi again and do the kingroot again)
It may take a couple tries but when the app goes real fast then goes to 100% then you will be rooted

Caution****If the phone restarts root will be gone then you have to do it over****
Do it over and over until it (Percentage) goes real fast (usually on 3rd or 4th try)

Have command open and copy and paste these commands real quick then press enter after the commands if needed
Accept adb shell on the phone to be able to get su and as soon as it's granted type
adb shell
su
dd if=/dev/zero of=/dev/block/mmcblk0p10
dd if=/dev/zero of=/dev/block/mmcblk0p13
dd if=/dev/zero of=/dev/block/mmcblk0p14
dd if=/dev/zero of=/dev/block/mmcblk0p15
(These commands are credited to Ecs87...He looked up the mmcblk's)
After That Restart the phone and the phone will be OK
This is what it will look like if you did it correctly....

If still on Binary firmware, just write cert if imei is/01
You can use Z3X with it just like that or with gcpro you might have to reset/write default efs.

Last step is to flash the phone back to stock.
