Is my Mi 9t bricked? - Redmi K20 / Xiaomi Mi 9T Questions & Answers

Hello. I recently tried to flash the latest fastboot global rom which included locking the bootloader. I used the latest miflash unlock program and everything went well and displayed the green "successful' when it was done. But when I rebooted to the system it loaded directly into stock recovery and boot loops by itself, restart>recovery>restart>recovery etc. It also displays at the bottom of the recovery screen "This MIUI version can't be installed this devise' but I'm sure I flashed the right one.
Now I don't know what to do. If I try to reunlock the bootloader it doesn't go through because I haven't linked my account to the phone (and cant do that because it wont boot up properly). I've tried wiping data in recovery but that doesn't change anything. I can however boot the phone into fastboot and also ADB but I don't know what to do from there. If I try to erase the data via fastboot I get an error saying it can't do that on a locked devise.
So I'm really stuck here and if someone knows what I can do (if anything) I would really appreciate your help.

Unfortunately, classical case to seek a paid EDL support
Btw, I don't know did the ROM really forced relocking BL or you didn't pay attention - there was an option in MiFlash to avoid relocking BL (unfortunately, by default it is enabled and many users then come to the same situation and have to seek for and pay EDL support, if anything goes wrong while flashing the ROM - one must disable relocking BL to stay on the safe side)
You should look around XDA if you can find somebody (it's not allowed to advertise, hence most posts would be deleted) or ask on Telegram or similarly

Hi thank you for your reply. I wanted to lock the bootloader as I was going to sell the phone and wanted it all back to stock standard. What does EDL do exactly?

It's very deep flashing. Something like how they flash the phones when they are assembled - they have to flash Bootloader and everything

After Pie: Bootloader unlocked & TWRP install didn't work

Hi,
I was really unhappy with Pie and tried to prepare my device for Oreo downgrade.
What I did was
- unlock bootloader
- tried to install TWRP
- mixed something up in that processs
- realized TWRP cannot be installed apparently on Pie right now
- MiFlash seems to be not working as well when trying to install stock rom (says flashing but nothing happens)
Well Pie is running right now, but when trying to lock the bootloader again for future updates, the phones is only showing a black screen.
After that I am trying to unlock bootloader again (fastboot oem unlock) and everything works again, except when I try to boot into recovery ("the system is destroyed" or something like that).
Trying to "hotboot" into TWRP currently is also not working, "unable to mount..." and after that automatically reboots into the system itself.
Any idea how I can either put a standard Pie installation with working recovery and locked bootloader on?
Or how I can maybe install Oreo instead? As I said, the MiFlash tool doesn't do anything (tells me "flashing" but actually doesn't do anything).
Thanks for your help!

can you explain us the procedures that you have followed to downgrade. It would be really helpful. i have tried this
method but it didn't work for me. i am facing IMEI 0/no signal issues using this method.
Thanks
well I have done a lot of stuff that made my phone not working anymore because using a wrong .img file and didn'T understand the tutorial (same link you have provided) fully.
But at the end it was quite close to the link you have sent, the MiFlash tool I needed for example to try like 10 times per step until it worked, maybe a bad cable - I don't know.
But finally it was working, after March update without network signal, but with /boot & /efs partitions and Nov fastboot image, it was working.
If you need any more detail for a specific step, you can of course ask and I can check if there was anything special I can remember

i already tried:
wipe data - finished with ok (all my data gone) but still same issue
connect with mi assistant - no connecttion to Software
someone any ideas - thanks for any help

Since you already lost your data, try to flash the ROM again. I don't remember if you can transfer/flash the stock ROM without an unlocked bootloader (I suppose it is locked), if you can at least dirty install it as an update it may work too (google it). Unfortunately, providing more information over unlocking the phone is inappropriate.

can u pm me please?
u are the onle one who relied to my post
thanks in advance
Since your bootloader is locked, your options are limited.
To expand a little what i mentioned, your best try it may be to try and update the current from from the stock recovery. That may fix a potential corrupted partition. To do so, you can follow the steps of method 2 in this article. However, I am not aware if you can transfer the update.zip in the phone... I suppose that the stock recovery doesn't mount the phone to the PC. Thus, you probably need to try and transfer if through fastboot but that may not be possible too (could check if adb push works or if you can boot a twrp recovery, not flash just boot, but you probably wont be able)...
If you can't do the above steps, you are in a half-brick mode right now with a locked bootloader. Generally, there is no official way to get around this.

LG V20 bricked/bootlooping/bootloader re-locked. How to fix?

Hi all -
I have two US996 phones.
Luckily, my primary phone is fine (rooted stock Oreo ROM)
The "backup" phone was previously bootloader-unlocked and also had TWRP and a stock-rooted Oreo ROM on it - but not yet set up; it booted to the welcome/setup routine.
Well, I did a "full" Nandroid backup of my primary phone (TWRP 3.3.1.0) using the beta feature supposedly allowing backup of data as well as the internal storage and wanted to see if it really did fully restore the phone without need for re-entering all of the passwords and other info for all of the apps. So, I tried to restore it to my backup phone.
Well...I screwed up and apparently didn't do an adequate wipe before flashing. Now, the backup phone is bootlooping with a message saying something like "your phone failed a security test and will not boot". I am not able to get into recovery at all.
I am able to get into fastboot mode, and on "fastboot getvar all", I see that the bootloader has been re-locked!! So, of course, trying to unlock it via fastboot doesn't work, since I am not able to get into developer mode to re-enable OEM unlock...any way to re-unlock it and get into TWRP?
Looked at Medusa Flasher, which is supposedly free (1.1.0.1) but when I try to use it I get "card not found" and it won't open, and the file needed to fix this isn't available. It also appears that it's only good for Sony and HTC phones anyway, and some serious hardware dissection is necessary.
Any help would be appreciated!
Thanks in advance.

Flashing a kdz would be your best option right now. It's safer to start from a rock-solid base

Flashed the Stock Oreo KDZ. Thanks! phone boots now....but I can't unlock the bootloader in the usual way (using the unlock.bin file from LG) because somehow the IMEI number got nulled - all zeroes.
Edit:
Got the IMEI fixed with this method: https://forum.xda-developers.com/v20/help/us996-imei-null-0s-how-fix-t3876980 - and now the bootloader magically became unlocked.
Now to flash TWRP and a rooted image and all should be well.
Thanks again, Landloord!

OnePlus 6T - Can't unlock bootloader nor get into Android

My OP6T had Ubuntu Touch (equivalent to Android 9) installed on it. When it broke, I tried to flash TWRP (version 3.3.1) to clear and reinstall Ubuntu Touch. For some reason it wouldn't boot, so I foolishly decided to flash TWRP onto every single partition. This only succeeded in breaking recovery mode. Following some advice I used the 6T MsmDownloadTool v4.0.58 (OOS v9.0.11), which fixed recovery mode, but not Android - it just showed the booting animation in a infinite loop (bootloop).
I've attached an image I found online showing the screen: bootloop
The issue is that I cannot flash in fastboot mode as the bootloader was relocked by MsmDownloadTool, *and* I cannot get into Android to enable OEM mode/USB debugging. I seem to have encountered a paradox where fastboot mode requires the permissions to be enabled in Android, but I can't boot to Android to enable those permissions, nor can I flash anything else to fix Android.
Is this possible to solve?

You can try booting with the twrp.img. "fastboot boot name.img" using that ADB command. If that does not work the only other option is to completely retore your phone using msmdownload tool. This method will also depend on whether you have the international version or the T-Mobile version as there are different approaches depending on the type of phone. Read and study carefully how to proceed. If the msm tool does not work I'm pretty damn sure there are no other options.

He can't boot into anything with bootloader locked. This is why msm tool sucks and people should stop recommending it for any little problem.
Only option now is to use msm tool again and hopefully get something working
Even with the bootloader locked you still should be able to boot the recocery image.
I have the 6T and 7T Pro. When I messed up my 6T my only hope was the msmdownloadtool. But make sure it's the right one.
When I had to use the msm download tool it did lock the bootloader. But I was able to unloack it again from the ADB command prompt at the bootloader screen by typing fastboot oem unlock. But this can only be done if it is set in developer options.
I spent alot of time trying to figure it out but later found outthat I was using the wrong msm tool.
Good luck. I hope you get it and running again because the 6T is still a very good phone.

Thank you! And yes, I tried that command but it is probably unset in the developer options (which I cannot reach, as Android isn't working anymore). I guess I'm using the incorrect version - how do you identify the correct one? I think I've used both the T-Mobile one and the other. I don't think the phone is T-Mobile, but I'm not sure how to identify whether it is or not.
It is very easy to convert a t-mobile variant to the international version. If you bought the phone used you would not know. One tell tale sign could be if you sim card holder supports either one or 2 sims. But that's not a sure way either because you can buy a replacement sim card holder. The fastet was would be to look up the IMEI # and see what variant of the 6 you have.
As for the msm tool you would needd a modified version of that tool. You first use it to downgrade to Android 9. Then you have to upgrade that verion of android 9 to a slightly higher version before you are able to fully upgrade feely to 10 than 11 if you wanted.
If you have the international version pretty much and version of the msm tool would work but a modified version would be best.
However, the first step is to find out which variant you have.
When you used the msmdownload tool which version did you use, and did it finish the job ?
If you have the t-mobile vesion there is a thread on here that gives you step by step instructions to convert from t-mobile to international along with the links to download the software. And even the modified version will know what variant you have simply by not working.
If you are able to get into the bootloader than you have a great chance of fixing your phone. Your phone is bootlooping so that tells me you can access the bootloader screen.
When I bricked mine I thought it was gone forever, I spent several days working on it but I was able to restore it. But I would never use the ubuntu rom on any phone that I care for.
When you are at this level it is very important you proceed with caution and don't just start flashing anything you can find. It will nake matters much worse.

No. Not without an unlocked bootloader. But booting into twrp would give you the ability to flash a ROM tho.

That's what I meant. Flash a ROM from twrp. Ok so if that works this guy can fix everything from there. Gonna be a hassle tho. Instead of rebooting to recovery I think you would have to shut off phone and fastboot boot back into twrp to change slots right?
Somehow I feel like that won't work but I'm not locking my bootloader to test it

As far as I can tell there's no way to flash TWRP without unlocking the bootloader. And there doesn't seem to be any way to do that without getting into Android. And I can't get into Android...
Someone else suggested using this tool (https://github.com/bkerler/edl) as a last-ditch attempt. I'm going to give it a try and hope for the best!
Thank you both for your suggestions.

[HELP] Unlock bootloader.

Asus' unlock tool for M1 is dead (network error, guess they just cut the line for older models). Attached one I had in my backup from who knows how long ago, since I couldn't find any working links anymore.
Trying unlock tool for newer devices throws "Device model is not supported".
Dev. menu option for OEM Unlock is not available in neither of "official" images.
Max Pro's unlock doesn't work for this device.
So am I really stuck with Android 10 Beta release? I guess it is kind of "win" considering this release isn't completely bloated by Asus, but it would still be nice to get TWRP and Lineage on it. Not to mention I really wanted to give the Postmarket try on this device.
I'm more than willing to be lab rat if anyone wants to try.. stuff.. on my device, at this point I wouldn't even mind if it got bricked in progress.
Alright I have not given up on this, yet. I've stumbled upon post from one of the Asus' moderators on their forums:
For ZB555KL, there will no longer be any system updates and maintenance (including server).
Sorry for any inconvenience it may cause.
Click to expand...
Click to collapse
What this means is there is no official way to unlock this phone anymore, as their unlock app has nothing to communicate with.
In the same thread, another user posted this:
I dont know if you are still looking for this but after working on it for hours what you are looking for is:
in fastboot mode type:
fastboot oem enable-unlock-once
will unlock the bootloader for you until the phone is reset. Just have to do it everytime you reboot back into fastboot.
Also if you're flashing recovery, these other 2 commands may prove useful:
fastboot oem reboot-recovery
fastboot oem reboot-recovery-wipe
Cheers!

Indeed using this, I was able to flash recovery. Multiple actually: TWRP, stock from step 3 of the post, OrangeFox, stock again.
Why? Well, booting into any recovery leaves me hanging on black screen.
I've tried TWRP, OrangeFox. Nothing. I have found stock recovery image as well, which I have flashed. Got black screen again. BUT. Thanks to the stock recovery image I've figured out it was actually working, since after pressing some buttons randomly (kind of stupid, I know, but I though its bricked at that point anyway) I've managed to wipe data and was presented with fresh startup. I'm thinking both TWRP and OrangeFox worked as well, its the screen that doesn't want to show things for some reason while in recovery.
So if any of you got any ideas why would any recovery present me with blank screen and how should I deal with it, I'm all ears. Or eyes..
