For this process we have to Flash 2 files, I have given their links below this Post.
- Please, keep in mind to install this rom you have to follow the heardest process. ( Much more Harder than Flashing 6.0 and 7.1 based roms)
- I can’t garranty your 100% success.
- You may be ended up with a Bricked phone. (Use sp flashtool in that case and Flash stock ROM.)
- I have not tried it so I can’t help you on any problems related to This rom. But you may ask Quy Trãn or Rama Febriansyah.
- First use sp flashtool and Flash MIUI First File.
- Now boot to Recovery and wipe.
- Flash MIUI X64 file now.
- Choose reboot to system, it will boot to Recovery again. ( That’s normal)
- Now again go to reboot manu, and this time choose reboot to recovery. Now it will show the boot screen of MIUI.
- Wait for atleast 5-6 min then remove the battery and insert it again.
- Now go to the recovery by pressing vol down + power button, then go to reboot manu and choose reboot to recovery.
- This time it will boot into system. Done.
