Simple question - Redmi K20 / Xiaomi Mi 9T Questions & Answers

Can I unlock the bootloader on my global mi 9t (K20) then flash unofficial twrp and use it to format device and wipe system then flash latest MIUI stable Rom via fastboot all without bricking my phone?
You know, since MIUI 10 has anti rollback feature.

No idea about flashing Miui but when u will unlock ur Bootloader it will format ur phone and u will lose ur all data and phone will be reset as well.

The only reason I wanna go through with this is to wipe system cause I want a clean install of MIUI since I ran into some problems with my device

Fix for WIERD LOCKSCREEN BUG on Android 8 and + custom roms

How to Fix for WIERD LOCKSCREEN BUG on Android 8 and + custom roms
Many of them are facing this Bug after setting up Lockscreen, after few reboots we face System UI FC when entering Unlock code or pattern. This bug is faced when using Oreo, Pie and 10. And this bug is not present on Nougat.
Warning You will loss your all data including your device internal storage and i will be not responsible for any bricks if it happens on your device
Steps :-
Step 1 :- First of all Download MIUI global stable FASTBOOT ROM from the link http://bigota.d.miui.com/V10.2.1.0....XM_20190114.0000.00_6.0_global_8a48e54fe3.tgz
Step 2 :- download mi flashtool and install on your pc and extract fastboot_rom.tgz to a folder.
Step 3 :- Important to have Official Unlock, if you are Unofficially unlocked try this method :- https://forum.xda-developers.com/re...icially-unlock-bootloader-redmi-note-t4009799
Step 4 :- Now copy userdata.img and persist.img from images folder to minimal adb and fastboot folder.
Step 5 :- Now open command window and write following commands -
fastboot erase persist
fastboot erase userdata
fastboot flash persist persist.img
fastboot flash userdata userdata.img
Step 6 :- Now "clean" flash a custom rom 8 or above it. And check whether this bug is still present of not. If you still face the bug then once flash full MIUI through Mi flash tool and repeat Step 5. Note :- After repeating Step 5 don't boot back into MIUI. After performing Step 5 quickly flash twrp and wipe MIUI and flash Custom rom.
Step 7 :- The bug will be gone.
I have made it easy.
If you guys have any Problem regarding this Pm or contact me on telegram my account @sk_ik_27400
Enjoy Flashing:fingers-crossed:
How many days have you checked? Actually after clean flash it happens after roughly one and a half day
One more thing, I am not officially unlocked, I use twrp with locked bootloader, should I try this?

i can 100 percent guarantee it will work i tried about 2 to 3 weeks no issues.
if u are unofficially unlocked then then i would recommend unlock officially using china dev fastboot rom because for many global dev or stable doesnt work
by the way u can if u flash with unofficialy unlocked bootloader then u will be stuck simply do is first of all flash all clean and lock then but remember use that fastboot rom which is recommended for unlocking unofficially rather than latest. then unlock its bootloader then on bootloader flash same image files i have said in above thread simple. also kindly check thread for unnoficial unlocking. http://en.miui.com/thread-345728-1-1.html
tap thanks if helped

yes after flashing image files from bootloader simply flash twrp and wipe everything and flash any oreo rom but remember once check in twrp recent screen that there is no warning regarding encrption
It was probably magisk issue
nathanchance said:
also @D-m-x (and everyone else), please try this Magisk build (it can be installed in the modules tab in Magisk Manager)
https://transfer.sh/YVFdi/Magisk-v16.7-1674-.zip
It includes a commit that should fix all of the weird issues with Magisk like the PIN not being accepted after a reboot or the phone getting stuck at the Google logo with the progress bar. The root cause is services crashing during the boot chain and either causing deadlock or lack of functionality. It's entirely possible that a service crashed during boot and started causing issues.

I flashed cardinal. I never set any lockscreen password or pin, only a set a pattern.
I couldn't flash persist from fastboot, as I am unofficially unlocked, I need to flash only using mi flash in edl mode.
Unlocking bootloader officially is a harrassment, always getting "couldn't add your account: error 20075" something like that

Xiaomi Mi9T Hard/Rock Bricked

Hello everyone i am in desparate need of some guidance where i unfortunately Hard bricked my Mi9t while trying to flash the new Mokee Rom.
Where i think i went wrong was wiping the system option in twrp. After reboot i was stuck on flashboot and unable to get back into twrp recovery.
I then proceeded to flashboot twrp, also used multiple versions of twrp, again to hopefully be able to get into twrp recovery with no prevail.
Also tried to fastboot via Miflash tool with all latest fastboot roms available currently but kept getting a anti-rollback error.
So then i searched a way to install recovery or stock rom manually via flashboot commands. This caused me to end up where im at, no fastboot, no recovery, no logo at all. I connect the usb and the phone wont turn on at all, just a dead phone. Power button completely unresponsive now, Vol-Up/Vol-Down + Power and nothing.
I worked on it for countless hours trying to simply get into fastboot now with huge anxiety thinking i killed my phone.
I left my phone to charge all night and woke up this morning trying to get into fastboot again and nothing again.
Can someone please lead me in the right direction???
Everywhere i look the info seems to be outdated. At this point i am willing to send it in for repairs but i live in Indiana, US and there isnt a Xiaomi Service location anywhere in site.
Sad story. What did you do in fastboot? If you can't flash a certain twrp version you would have to do:
1. fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img (in twrp archives)
2. fastboot erase recovery
3. fastboot flash recovery your-twrp.img
Concerning AntiRollBack:
You can bypass ARB in miflashtool, set the number of your new rom higher or edit the batch/shell-files manually. The first few lines are ARB and device-check.
I know the info comes too late, but maybe someone reads this before trying things the way you did. There have to be some EDL-pins inside the phone to reflash fastboot but you would have to open your phone. My opinion/solution: Cry and send in.
Anyway: Can you tell us what you did to wipe fastboot?

When i 1st attempted to recover twrp i used TWRP 3.1.1-2 fixed from 4PDA. Ran the .exe file and the prompt said both fires installed successfully, but when i did a reboot it wouldnt go into twrp anymore, just stuck in logo so i would end up back in bootloader.
ttp://en.miui.com/thread-942449-1-1.html
This is exactly the instructions i tried to use before i lost fastboot.
At one point while entering the commands, it froze then my phone completely died and could never make it do anything else.
Why the hell did you use an outdated tutorial for an other phone? A few of the commands also wouldn't work because there are only some of these partitions. But if you did it with the right firmware it shouldn't brick anyway. So maybe you were stuck at boot flash. Else you still would be able to boot into fastboot.#
I feel sorry for you bro but it looks like you were searching for a possiblity to brick your phone

I kno bro i felt like shyt believe me. Literally all day in panic and anxiety that i just wasnt thinking straight and using any kind of guide i can find and ended up here.
Made some progress today tho.
Since my device manager or MiFlash tool wasnt recognizing my device even when i installed Qualcom drivers and pushing all sorts of buttons lol,
I have now opened her up for some surgery and using the Test-Point EDL method.
https://i.postimg.cc/HWJGWHRw/test-point-redmi-k20-mi-9t.png
While USB connected and shorted these 2 pins my computer finally recognized my device in MiFlash Tool and Device Manager again as Qualcomm HS-USB QDLoader 9008 (COM3)!!!
Now the next problem is the MiFlash tool. I tried to flash rom and status states cannot receive hello packet. From what i understand, i need an authorized account.
Only thing i could find to bypass this was this but currently not yet working. - https://forum.xda-developers.com/mi-8/how-to/unbrick-mi8-edl-authorized-account-t3896677
Any ideas where to go from here?
https://mi-globe.com/unbrick-your-xiaomi-phone-without-authorized-mi-account/
https://c.mi.com/thread-1479882-1-0.html
I didn't need an authorized account last year but maybe they've changed something. The guides are up to date so maybe follow these steps.

Already ran into those sites and actually am currently trying out S-Unlock service to bypass Authorized Account with there XiaomiTool v0.01, and unfortunately again with no prevail.

As you can see i got passed Hello packet, but now it doesn't go passed this message or looks like it didnt do anything.

Already contacted S-Unlock Admin and now waiting for response. Im assuming im using the right Flashboot Roms. Tried latest flashboot roms from here available. https://xiaomifirmwareupdater.com/miui/davinci/
I also emailed unbrick.ru if they support K20/Mi9T variant and waiting for there reply.
Firmware on your page is not up to date. Use https://mifirm.net/
What device do you have? EEA/Global/CN? And what flashfiles did you use? I'm asking this because the only way I know to brick your device is to flash global/eea-rom on chinese device and lock the bootloader.

Hey,
I'm in a similar boat but I still have fastboot.
I can flash everything I wan't. But flashing a recovery doesn't do anything.
I can not boot into the recovery.
When I boot into the recovery i'm at the bootloop screen.
My PC does recocgnize it as recovery mode tho.
Anyways is there a way to get out of this mess? I wanted to try to flash with miflash over fastboot.img but I can't find any .img to flash.
All I can find are the .zips for twrp.
I didn't want to flash cfw tho. I got into the mess because there was an update today for stock rom and I flashed it with twrp. Because OTA didn't work.
/edit
I found the fastboot files.
But how do I bypass the antirollback error

to bypass the ARB you can edit the batch/shell files. the first few lines are device-check and ARB. you can also use xiaomitool and select it there.
Edit: I had the same problem with a twrp version I had installed. After switching to russian version I couldn't downgrade twrp. Just try one of the other 2 versions available.

I've had the russian version of twrp that didn't allow backups.
I know tried all the other version as well.
What happens is it stays in mi.com unblocked screen and my pc will recognize that it's in recovery but twrp never opens.
Like I said the normal stock recovery is flashable but all other twrp versions don't work for some reason.
I've tried all 3.
I know where the lines are but idk what to write in there.
I tried to just delete the lines and then I've got a different error.
Also when changing the version number it says success it actually flashes for 0 seconds and nothing happens.

The russian version I've installed allows backups, tried allready.
You can simply remove the lines, just care you dodn't left something or delete too much. Use xiaomitool v2, it'll bypass the lines.

If i download the xiamitool v2 and choose my device is bricked it says feature is not available yet.

If I choose mod the phone it says my phone serial and all the 3 other things are unknown.
if I select my phone my phone reboots and says waiting for debugging mode....
Then if I delete the ARB lines and try to flash via MiFlash it says error error no such file found
Can someone pls give me some clearer instructions.
Ok I somehow fixed it.
I flashed everything manually like the times before twrp existested.
Now I don't have the OS running but a running twrp.
I could flash xiaomi eu now and be done with it. But I actually wanted to use stock rom and not a costume rom right now because I wanted to switch to a costume rom when a good official comes out whenever that is.
Although flashing the stock rom got me in this mess in the first place. I never had this problem with flashing costume roms.
Anyhow I know this might not be the place to ask but are xiaomi eu and stock actually that different? Also are there any downsides in using it over stock?
My experience on most phones was that early costume roms usually didn't work with all features etc.
/edit
alright who gives a dang I just flashed the eu rom to be safe with updates..
anyhow is it normal that my devices says Redmi by Xiaomi now?
Prior on my stock rom it said MI by mi.com or something

Basically it's (xiaomi.eu) debloated and optimized but sadly based on chinese official rom. That means no widevine L1.
In my opinion the best rom is EEA (because of "spy restrictions"), debloated with ADBTools with same optimizations which come with mi-globe rombuilder (gpsset, preinstalled magisk, adaway, removed apps). Sadly mi-globe is based on xiaomi.eu which is based on chinese official.

Could you explain the steps you did to flash ALL manual? Which Commands? Which imagens?

Well i did instal xiaomi.eu now. Not because of optimizations etc.
The only reason is that like i said i don't wanna brick by updating official roms anymore.
I mean maybe it's my bad since I'm running costume roms on all my phones for about 12 years or longer.. can't remember when I started but I think with first xyanogen mod.
And I don't know how to flash stock roms.
But with a costume rom it won't brick and if it does I'm not loosing twrp again.
For debloating I do that myself with the android terminal. So idk what the rom has on bloat I'll just uninstall it.
My only fear was that main features don't work with the costume rom. But from first sight everything but themes work fine. And I couldn't care less.
Well one thing changed the icons look like a chineese appleish phone now. Oh well I'll change that later.
Other than that the fingerprint is more responsive which I do like.
And for some reason my Modelnumber changed from Mi 9T to RedmiK20. Even on the boot it says Redmi now instead of MI.
Idk if it's because of the ROM or because I manually flashed the phone.

Just download the fastboot rom and flash everything but dummy. You can flash dummy to but that is just for ARB. Depending on what your ARB index is you can flash it to ignore future problems.
My index was 1 tho and apperently if it's under 4 ARB is supposed to be irrelavent.
I'm not to sure on ARB tho because it's my first time dealing with ARB.
Other then that u flash everything else.
You will end up with a phone that is empty. Basically you reformate your phone so nothing is on there but TWRP. My phone was at 59gb/60 or something like that. basically the only folder I've had left was twrp.
Like I said I remembered the method from like 8 years ago when we didn't have twrp.
The problem with this method is that you can easily hardbrick tho I think. Since if it doesn't work you turned your phone into a fancy usb drive.
I only did it because I thought of buying a new one so since the phone was dead in my eyes already I just tried the old method and it worked fine, besides rebranding the phone to RedmiK20 from Mi9T.
Anyhow if your not giving up on the phone yet I wouldn't try it. Only try if you wanna throw the phone in the trash anyways.
just like me , for the anti roll issue u need to flash newers rom like from latest u flash on ur device before (recommend V10.3.11.0.PFJMIXM) u can get on mifirm.net . after download rom extract the file into fastboot tools then copy all .img file into fastboot tools . after that open the fastboot mode on ur phone and tools on pc
then flash this file
fastboot flash dtbo dtbo.img
fastboot flash logo logo.img
fastboot flash vbmeta vbmeta.img
fastboot flash boot boot.img
fastboot flash misc misc.img (u can get on fastboot rom not .zip)
fastboot flash recovery recovery.img (recommend used twrp-3.3.1-2-davinci-fix)
then try reboot phone into recovery
if work let me know . im trying make this method because before this i got this problem to after flashing paranoid rom without format data .

Don't know how you manage to brick your phone with official firmware tbh. And why should you lose TWRP? I flashed about 10 times (global, eea, chinese, xiaomi.eu, mi-globe) and I still didn't have to reflash twrp once. It won't even touch the recovery partition. I also don't see a reason to mess with fastboot (except your brick haha). The boot behavior (redmi instead of mi) is fine, depends on the rom you've flashed. If you flash global or eea rom it'll switch back to "Mi".
What do you mean by "I don't know how to flash official rom"? Boot up twrp, clean dalvik cache/cache, install... tadaaa. I was also using custom roms on all of my phones but I can't find a reason for now to do so. I see only bugs and things not working. I want my widevine L1 and I want AndroidAuto to be working. I'll stay on global/eea till a good rom pops up.

I mean yeah that's what i thought just flash a official rom like any stock rom. Or rather if you change roms cuz if you update existing roms you don't really need to wipe anything anymore.
But apperently it busted my whole phone. It was a weird brick. My phone wasn't recognized as a phone anymore in fastboot. But it was recognized normal in adb. So I needed to change windows drivers to make my phone recognize.
And after that nothing booted but stock recovery and even then it said I don't have debugging enabled. Eventho I was connected to adb??
Anyhow I think the flash messed up the whole system partition. So what I did is in short formate the whole drive and start with a clean slate.. anyhow don't need to repeat all that.
But yeah I'm with you with the take on costume roms. I don't see the need anymore since most stock roms are decent nowadays and costume roms especially are most likely buggy somehow. Good thing is that most stuff I need in my phone is working on the eu rom. Like I said only thing that I could find not working are themes. But thats ok.
I don't know what that widevine L1 thing is. So I prolly don't need it. But maybe u can explain it to me Always up to learn new things.
Well for now I stick with the costume rom since it's basically no different to me. And the chance of bricking again like that with a costume rom are slim to none. If the phone brick it's most likely just a simple brick that can be fixed with twrp. and if that doesn't work by booting into twrp from adb.
Btw that didn't work on my weird brick either. I couldn't boot anything from adb. It gave me a black screen when trying to boot something.
Anyhow I'm glad I've got it running again. But somehow I'm not that surprised. Most times when I brick phones I can fix it when I'm at the point where I wanna throw the phone away. Cuz then I'm just flashing everything I can to make it work xD.

mi9t loop to TWRP recovery after install MIUI 11

Hello
today I got an update for MIUI 11 by OTA, I press agree for "UPDATE", my phone restarted to TWRP, it's Installed some files for update, after finished that my phone keep restarting to TWRP recovery again (LOOP)
I tried to download official rom and install by TWRP ,but after finish and restart device still rebooting to TWRP recovery
is there any solution for not losing my data ?
BTW : flash stock rom didn't remove TWRP recovery , why ?
(I download rom from xiaomifirmware [dot] com)
I am not expert on that field but from my knowledge try booting twrp and copy all your files to your pc or laptop (the one you need at least for saving some photos or videos ) then flash a fastboot ROM
And as I said from my knowledge not sure there might be other ways

Your phone was on a custom ROM but you didn't know it? oO
No Official ROM will boot and auto-install in TWRP...
Try to clear "Dalvik/Cache" and if still not booting then you will need to "Format Data" in TWRP (loose data).
If still not working, flash a fastboot image...

Try flashing the fastboot ROM the .tgz one not the .zip using miflash but try to use the miui 10 one and later on update (getting the phone to work is more important right now )

Then if you can fully boot to twrp try to connect it with an otg or to pc and copy Ur files
It happened to me once btw I deleted the system partition(first time flashing) ? then I flashed the fastboot ROM
If I was in Ur place I would never flash any custom ROM to trigger the anti rollback or lose widevine l1
You may try but be careful of going through wrong things such as edl mode

God bless us
I’m not using custom rom at all
BTW is there any way to delete twrp recovery without delete system ?
Did you by any chance flashed with the greek TWRP? I got the same bootloop so I get back to miui 10 official global version (the one I updated from) and it booted alright without wipe needed...
I'll try other TWRP versions as well though but right now I don't think I wanna update :|
Yup you should disable disable dm verity and verification
just flash this using fastboot and you're good to go, I am now running official miui 11 without wiping the data.
Code:
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img

Reflash the official twrp and flash the extended ui ROM. It isn't bricked
This happenned to me too.
If you can't boot or flash twrp via fastboot in this state (It wouldn't work for me), download and flash the fastboot ROM for your device and use the flash_all script (careful NOT to use flash_all_lock!!!!!). It'll go back to stock and keep the bootloader unlocked so you can flash TWRP and start over.

How to downgrade from 11 to 10 without TWRP

Is it possible to downgrade from 11 to 10 without twrp? And without wiping my phone?
You will be wiping your phone if you want to downgrade from A11 to A10. No way around it.
Hi , how I can go back to A10 please ?
No. Downgrade will wipe all in youre phone, but it can be done just by flashing downgrade rom with Settings > System updates > Local Upgrade.. No twrp needed.
Can I have link for your method please ?
I really want to go back in A10 , android 11 is **** even if I need to wipe my phone
"Downgrade zips (will wipe your data)"

Choose the one for the region you live in !
Thanks bro it's working
The MSM tool is a way back. Never done it but should be safe.
dladz, my friend, MSM is the ultimate resort, when you got booboo..
1.Downgrade rom
2.FastBoot rom
3.MSM tool
I am on stable Android 11 , want to downgrade to 10 . Do i need to download the downgrade zip file or the regular os file will work ? Downgrading from Stable 11 to Stable 10.

MsmDownloadTool is the best way I found to downgrade from OOS 11 to 10. I have tested on OP8P. If you use the tool your data will be lost.

Ha.
I'll be honest I've never used it pal.
Seems to be the only way without twrp.
The times I've not been able to boot I've just wiped system. Always does the job.
I used a few times Downgrade, FastBoot rom, MSM on my OnePlus phones, since OP3 to OP 8 Pro. All of these are Life Savers.
And i did a clean flash all the time, till the latest 2 phone models.

Sometimes you will need to use MSM Tool.
It's possible to break only one partition and there is only one way with MSM to fix that. Even fastboot rom or OTA won't fix that. I had that once with my OP7T and also saw some other guys reported that issue.
