This guide only applies to the phones with region number C636!!! I'm not responsible for what you do with your phone, take your own risk.
This guide will erase all the data on your phone, so backup before following.

If you downgraded your phone to install GMS and then your phone&HiSuite keeps telling you that 131 is the latest version, this guide is for you.

All credits goes to "GSMFix" youtube channel and "Ictfix" website.

1) Get a USB OTG cable/stick (USB Type-A to Type-C). I got mine for 1.5 Dollars at Mr.DIY.


2) Download this file. Firmware

3) Copy the "Dload" folder to your USB stick.


4) Using your OTG cable/stick, insert the usb stick to your phone.

5) In your phone dialer, dial *#*#2846579#*#*

6) Click on Software Upgrade


7) Click on Memory card Upgrade


8) Wait patiently. Upgrade should take around 10 minutes.

9) After you boot into your phone, set up your phone and install GMS using Googlifier.

10) Voila! Now you can update your phone in the settings! First, it will update to and then
