Flashing MI9t pro - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

For some reason ,I cannot post this on Q/A Thread. Is it possible that my flashing to stock ROM mi9t pro global (with MI FLASH TOOL) lasts over 1 hr? This is second time I'm trying to go back to stock.

Nope, normally it's just 500-700 secs

Yes you can flash the Indian ROM, just make sure you change the flash option to 'clean all' in the Mi Flash Tool. If you forget to do this you will brick the phone.
I believe that your phone will show K20 Pro in the About Phone section, after flashing.

Thanks, only CLEAN ALL and i should make sure the LOCK isn't ticked if my bootloader is unlocked right?

Why would you want to do that?
You gain nothing that I am aware of and lose NFC.

You gain MIUI dialer app which has call recording. Plus POCO launcher as standard, with its app drawer.
So if you never need NFC there's reasons for choosing the Indian ROM, if you want to stay on official MIUI.

Fair call. I forgot the global rom doesn't have the miui dialer. It is the reason why I am still on my original china rom and have not flashed the global one yet.
Hi guys,
I'm a Mi 9T Pro user and want to get rid of google dialer & messages too. I am about to unlock my phone and flash the Indian ROM.
I wonder what is the lastest build of Indian ROM and where I can get it safely?

K20 pro ROM on Mi 9t Pro

Hello everyone, sorry for my english, I bought a mi 9t pro from second hand and it seems that the previous owner installed a k20 pro rom on it, I know this because on the back has the MI logo and not the redmi, and because the 4G band works fine on my country, but it sets Redmi on boot logo, on device name, and some other places. So I wanted to know if I can install back the mi 9t rom even if im on miui 11 android 10.
I'm still waiting the 7 days to unlock bootloader so no rush for me.

Yes you can, download the appropriate fastboot ROM and flash it with flashtool. Make sure you check on CLEAN ALL and not CLEAN ALL AND LOCK

How do I install EU ROM if my phone it's on MIUI 10 (mi 9t pro Global)

Hi, I have the mi 9t pro global version non EEA, it is on miui 10, still no update. I wanted to install EU rom but it's based on MIUI 11. I didn't know this a while ago and flashed over it and messed up my phone, and after that i wipe system and got even worse... it was on a bootloop to fastboot but I managed to bring it back to life. Now I want to do it the right way but don't know how since there are so many versions of the K20 pro/Mi 9t pro and I easily get confused by this. I came from a poco F1 and it was a lot easier, never got a single issue but well, I like this new phone a lot more.
Sorry for my bad english
Hey, first you have to unlock the bootloader, then with the XiaoMi Tool V2 application you can do it in a very simple way.
All tutorials are here Xda Dev or in the Xiaomi MIUI forums themselves.

Flash MIUI 10 fastboot ROM. There's no Anti Roll back protection for our phone.

Hello, i want to revert to from android 10 to android 9. Do I have first to unlock bootloader right? And then i just need to flash via miflash the correct rom? Does it void the warranty or mess up with L1 support? Thanks

Before you go back to 9 search for rotation problems, apparently auto rotation gets messed up. I went back to 9 and have that problem.
why everyone need revert back??
so curious

For me the reason is mainly the battery. I was on MIUI 10, Android 9 for just a week before update to MIUI 11, and as far as i remember, battery was lasting way longer than it does now, so i wanted to give it a shot...
yes there is a big SOT difference (in my case android 9: 10h+ SOT, Android 10: ~7h SOT)

I was really relieved that I didn't update to miui11 android 10 yet
me on MiuiMiX_2.3_raphael_V10.3.17.0_V4_v10-9_20190927.zip on Sept 2019
hope u all can downgrade to miui10 again..
Hi, I just bought a MI9T PRO a couple of months ago and I've made the stupid mistake to update it to MIUI 12 (Global Stable 12.0.1.0 qfkeuxm) which I don't like at all (animations, scrolling, speed...)
Now I want to downgrade it back to the original image that came with MIUI 10 (Global Stable 10.3.1.0 pfkeuxm) but since it's my first xioami phone after many years with samsung phones, I have some questions:
1. Is downgrade possible between these 2 versions of MIUI?
2. Can I flash directly MIUI 10 (10.3.1.0 pfkeuxm) from MIUI 12 with MiFlash if the Bootloader is Locked?
3. If bootloader should be unlocked in order to downgrade, which is the official app and steps to do this?
4. Does MI9T Pro with MIUI 12 (2.0.1.0 qfkeuxm) have any antirollback on it to prevent downgrade?
5. If I manage to downgrade it to MIUI 10 will all the sensors work? (gyro, wifi, bluetooth, wifi, HD videos, nfc)
About this I've read that I might be needing to backup persist.img and reflash it. Not sure how do I do that, from current MIUI 12 installed on my phone, from the fastboot image of MIUI 10?
6. What else can go wrong or I need to be aware about the downgrade procedure?
I don't want to root it, or to install custom roms on it, just to revert it to the previous stock image of MIUI 10 if possible.
Thanks.

1. Yes.
2. No, you need to unlock the bootloader. It can be locked again whilst flashing MIUI 10.
3. You can follow this guide to unlock, from the official MIUI global forums.
https://c.mi.com/thread-2262302-1-0.html
4. Not that I'm aware of, there's been none so far on all other versions.
5. They should all work fine. You can extract the persist.img from the MIUI 12 fastboot ROM.
6. Make sure you are flashing the correct region for the phone. If you flash the Chinese version, in error, and also try and lock the bootloader, you will brick the phone.
Follow this guide to fastboot flash MIUI, again from the official forums. If you read it on a mobile browser, you will need to view it in desktop mode.
It has links for the Mi Flash Tool.

9t Pro with MIUI 10 -> 12 with OTA

Hi!
I have a 9t Pro that's rooted and have 10.4.6 for k20 pro.
I installed this right when it was released last year and didn't touch a thing since.
Now I would like to update to MIUI 12 in the most simple way, and also keep OTA updates even if it's rooted. Is this possible?
What method can you recommend?
