I had 6.1.18 on my Mi4c.
Whatever I did try I can't get SuperSU installed in 6.2.25/18, also there is no twrp in 6.2.25/18 after flash.
This is what I have tried (5+ times):
1- Download rom, twrp and supersu from the firstpost: OK
2- Install rom with updater: OK
3- No twrp
4- Install supersu from updater/recovery: Phone can't get past the MI logo (and gets hot).
5- Back to recovery and reflash 6.2.25 ROM: OK
6-The same as 3
I did this with 2 different supersu downloads and with 6.2.18 it is the same.
So, everything looks normal except that I don't have twrp installed and that the phone hangs if I try to flash supersu.
I also tried to flash twrp after flashing 6.2.25 but no twrp after boot.
What do I do wrong?
Edit: I now have supersu installed and working. I can't see twrp but recovery is from twrp version 2.8.7
What I did is flashing twrp and supersu queued from the recovery.
One last question: Is it necessary to get twrp also from appstore to get ota updates?
Edit2: Thanks @
coccioline, I will wait with updating to the new twrp version until it is necessary.
