You don't need to root but the bootloader has to be unlocked.

As said, you don't need root, I always flash roms without root.
Just unlock your bootloader with official tool and then you can install TWRP recovery or push the rom with fastboot mode, TWRP is more convenient for me

Can anyone confirm this? There's a new OTA update available for mi max 2 but I'm not updating coz I'm waiting for 72 hours to complete so I can unlock bootloader. I'm kinda worried that if I update my device to miui 9.2 I might have problem unlocking my bootloader. So I'm thinking to unlock my bootloader first & then update my device thru OTA update.
I've got them but don't launch the upgrade because, if I do that, it remove my twrp by re-flashing xioami stock recovery.
I've got a global beta rom, bootloader unlocked, twrp installed and rom rooted.

oh wow, so even with all that ota updates are possible, good to know
flashing twrp isnt a big deal though, just boot into fastboot, connect to pc and input a command, thats it not like u need hours of work to get it done
would be interesting to know if the rom gets unrooted on update.

I received a phone with an unlocked bootloader. It just received V9.0.3.0.NDDMIEI
I don't know if it's just the China model reflashed with the English ROM or what, but it's definitely got an unlocked bootloader and I'm not sure why.

Am I correct in thinking that the update would have reflashed the recovery area and eliminated anything that didn't belong? I put TWRP on it and I'm going to load a stock ROM through TWRP.
I'm wondering whether I've gotten ahead of myself and I should have gone Stock ROM-->TWRP-->Stock ROM with root.
I'm also not sure if the rooted stock ROM will allow me to enable LTE bands just by changing NVRAM settings in QPST. Does anyone know if the bands are blocked in MIUI as well?
I run unlocked boot loader, global stable and Magisk.
Every OTA, I gotta reflash TWRP, and reinstall Magisk, but yeah, I can OTA.

How do you install OTA? from the updater app in the device OR full Rom in twrp?
I just use the updater app, it reboots, and then proceeds to flash and remove TWRP and Magisk.
The only time that I've used TWRP is to flash Magisk.
Just I want. I only need TWRP to flash Magisk to enable use of Titanium Backup Pro and any adsblocker.
So Flashing TWRP via fastboot, then using TWRP flash Magisk. Use mobile as usually and when i update via OTA, reflash TWRP and Magisk, true?
EDIT: After flashing Magisk, flash stock recovery via fastboot so mobile is ready to OTA update. Right?

Yeah, just choose to download the full rom press reboot and it'll upgrade, then flash TWRP and Magisk again.

so you are saying ota update through updater app is not working?
do i need mi app on pc to update,that too after downloading the full rom for every update?
status: bl UNLOCKED ,root-NO
I dont think so, if you allow replacement of twrp by stock recovery after magisk flashing i think it should be possible install ota using update app. When its done, then reflash twrp and magisk from it.

Mi8 Doesn't Boot

I have installed TWRP and then wipe everything(including Internal Storage accidentally). I installed xiaomi.eu stable rom and phone stuck at MI android screen. Then try xiaomi.eu beta rom it is same.
What should I do?
If you have unlocked BL use mi flash to flash stock rom
Flash stock rom using miflash 2018 (portable) since your bootloader is unlocked, make sure you choose clean all, DON'T choose clean all and lock at the bottom of miflash screen before you flash the rom, other wise your device will be bricked.

Thanks, it worked, I solved it by installing rom with fastboot and I know why TWRP doesn't work. Because of encryption. https://forum.xda-developers.com/android/software/universal-dm-verity-forceencrypt-t3817389

Unable to keep data decrypted..

Hi all,
I have a Mi 9 unlocked and was able to install several ROMs on it, Xiaomi beta, Xiaomi eu, PE, etc... Every time I switched the ROM I formated data (the option where you are asked to type yes) but everytime when I go back to TWRP, I have to enter my pattern to decrypt data... What am I doing wrong? Formated at least 3 times data and everytime I loose everything including sdcard storage... Any help ?

Yes but why I need to flash something when TWRP is able to decrypt ?

anyone with a Root guide?

Guys, i know it is pretty early, but has anyone got the slightest idea on how to root this bastard?
Wouldn't call it a B lol, waiting for mine to arrive and would certainly love to root it also
Here is only guide i've found, and i have successful root:-
https://forum.xda-developers.com/galaxy-a71/how-to/galaxy-a71-root-unlock-bootloader-flash-t4047847
yes, would be nice to have a better root guide - the one you link to is very difficult to follow.
Yes the programmers language is different. Things are obvious to them that are not to most.
For example it says
WARNING: You can't downgrade anymore once you flashed U2 update !
In this sentence I assume that downgrade means to root.
