Rooting for OK3:

The problem: The above phone can only be rooted with "kingroot".

After rooting, "kingroot" must be replaced with "SuperSU"

1) Enable Developer Options (tap,tap,tap...)then USB Debugging on phone

2) Settings/Security Check "Unknown Sources"

3) Install "Terminal Emulator"

4) Place and extract "mrw" folder of Replace_Kinguser_with_SuperSU-v2.4.zip in root of Internal Storage

5) Install and run KingRoot_pc_en.exe on to PC (no need to install "Purify") Accept un-Blocking

6) "Allow harmful app"

7) Verify Root with "Root Checker" (phone will auto reboot)

8) Enable Kingroot "Try it". Forbid Knox

9) Open Terminal Emulator. Wait a minute for prompt.

...fileatt:/ $ "su" <allow root privleges to Terminal Emulator>

root...fileatt:/ # "sh /sdcard/mrw/root.sh" (sdcard is the Internal Storage directory)

10) Wait a minute to finish back to root...fileatt:/ # prompt. Lots of errors.OK

11) Accept numerous "Unfortunately Kingroot stopped" errors.

12) DO NOT REBOOT YET! (need to preserve root privledges while installing Super SU)

13) Verify Root Checker is still rooted

14) Install Super SU from Google Play Store or .apk. Should ask to update it when opened and reboot

15) Run Root Checker <allow SuperSU root rights>

16) Super SU rooted without Kingroot!

-----------------------------------------

Reset Custom counter:

Install and run Triangle Away.apk

I don't know if this really helped

--------------------------------------------------

Helpful tips:

Reboot into Recovery Mode

Hold Power-VolUp-Home(?). When phone vibrates, release Power and continue to hold VolUp-Home(?).

Boot into Safe Mode

Press and hold Power until vibrates. Then Release. Now continue to tap Menu key (right of Home)

After factory reset, if phone won't boot, remove battery and short leads
