Xiaomi Mi9T/K20 Hard brick recover tutorial - Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D

Hello to everybody.
Dear friends I post this to guide (only unlocked bootloader rooted phones) you through the steps that I used to succesfully recover my Xiaomi M9T
from a hard brick (by that time only edl mode was available).
Since Xiaomi has decided to lock down their Mi flash tool, and only special authorized accounts have an access to their utility tool.
was almost impossible (by yourself) to recover your phone from a hard brick situation.
I found a way arround to xiaomi tool with a 100% succesfull 1st atempt with my own phone it worked flawlessly.
Forget the point to point jumbers with a required open phone procedure.
Forget the authorized account holders with a teamviewer use of your computer and a fee for their services (logical).
Forget returning back your phone to any authorized repair center for a revival for what ever cost.
Below you will find al the steps one by one.
First thing you need is to install: minimal_adb_fastboot_v1.4.3_setup. https://forum.xda-developers.com/showthread.php?t=2317790.
Run it and put "Y" and hit enter all the way through.
Second you need to install: TOOL_ALL_IN_ONE_2.0.1.1. https://forum.xda-developers.com/android/software/tool-tool-one-driversunlocktwrpfactory-t3358711

Press tab advance options.
under the advance options window press first the tab Set ADB and fastboot privileges system wide.
It will asc you for confirmation press the tab again with the same Set ADB and fastboot privileges system wide.
Then press the tab Open a free terminal with ADB and fastboot privileges.
and type in the terminal the cmd fastboot oem edl,
It will say ADB boot oem edl OK. (unforunatelly I have no screen print from this one).
You will know at once because your phone goes from fastboot (bunny) screen to black screen and enters edl mode, is normal do not be alarmed.
In your computer you will see now under setting> devices> Qualcomm HS-USB QDLoader 9008. That is a good thing you are now in edl mode.
From there go back to already running all in one tool.
Press the tab Flash Factory images, you will go to the respective screen (below).
Select Flash all, and press the download factory image china.
Immediately will redirect you by a pop up window to the chinese site of the MIUI.
Scroll down and you will come across the Redmi K20 rom, downloaded and save it to your desktop.
Once is done decompress twice from tgz. file, to tar. file, to ready to flash rom file.
Now come back to all in one tool, and select the rom from the browsing tab, go to the desktop folder where you have previously download the roam and select the ready to flash (unzipep file) once is loaded hit flash Rom and seat back.
The ADB terminal will start the flashing procedure you will know from the very beggining if everything is normal,
Because the terminal shows the file is being prossesed and the time for each action with a followed OK
During the procedure it will break up between two or three stages of the flashing, momentarily again do not be alarmed.
If everything goes well the operation will finish with a gorgeous redmi bootup logo.
(once again I apologize no screen shot taken in advance for this step)
It will finally bootup to system, allthough it might not, But one more time do not be worried, officially you have succeded reviving your hard bricked phone.
From there if is not completing bootup simply press volume up+power botton and you have the official recovery, (in chinese of course) but you can easily
find an image with the english tab designation, hit wipe data, and reboot again, voila there you are back in bussiness.
All the gredits go to the developers of the above used tools, since I just was lucky enough to find the way through.
Good luck to all Mi9T/K20 xiaomi owners with your phone revival process.
Best regards to all of you.
P.S.
Forgive my English for any syntax or grammar errors.
I wish I had more time to spend for a more comprehensive guide.

Hi there I have not tried since I have only Mi 9T.
But yes, I am sure pretty much is the same think, instead of downloading the K20 rom, simply download the K20 pro one,
I wish you a good revival.

---

wow, this is too good to be true ? hope it will works for ppl who have brick. thanks

---

Awesome news, THX

---

Thank you for providing us an alternative way of reviving hard bricked devices. I hope this also fix similar problems but with a locked bootloader.

---

btw can i just unlock bootloader easily from this tool?

---

@Fantomduck Wait wait, i missread in your post "(only for unlocked bootloader)" So this is tutorial for those who have already unlocked bootloader to unbrick device or what? im confused now... bcs if we have unlocked bootloader there is no point to do this steps u described then, we can simply flash any stock rom on unlocked bl and unbrick drvice.

---

Yeah from what I understand, it basically flash the rom via EDL mode, but for unlocked bootloader. But why bother with EDL when the bootloader already unlocked? Also, I thought we can only flash ROM via EDL with authenticated tokens?
If this app can flash rom via EDL without special authentication, it should works for both unlocked and locked bootloader, though it might be different for Mi 9T Pro.
Very interesting nevertheless.

Hello again,
Just a clarification regarding, "I tried one more ultimate time, and boom success".
I ment tried one more time, by using alternative ways such the one that I post .
Not the Mi flash tool.

Well I guess thanks for taking the time to write this guide, however it's not applicable to hard bricked phones, and all the AIO tool does is use fastboot commands, that's the reason it requires fastboot access with unlocked bootloader.
Hard brick means :
- No fastboot at all. No way to boot to it on the phone. Plain black screen and nothing else.
- Stuck in fastboot with bootloader LOCKED and wrong ROM installed ("system has been destroyed"/"this MIUI can't be installed on your device")
Unfortunately for hard brick cases your only option will still require an authorized EDL account (and short the test pins for the 1st case) and only by using Mi Flash Tool.
Hi, yes I flased my phone via EDL Mode since I had no other option, (hard brick) the system was erased by a terrible mistake and the phone was only opening to fastboot mode, no matter what. And if you have hard bricked device you can not flash it in fast boot mode simply because your computer can not see the phone.

If your phone can boot to fastboot and the bootloader is unlocked then it's not hard bricked and can be recovered simply with fastboot commands. If you couldn't see the phone on the computer it was probably because of missing drivers or possibly fastboot/adb not running with admin rights, which I guess the AIO tool seems to fix with the "set ADB and fastboot privileges in system wide" option...

---

Yeah I thought so, as that app is basically a GUI version of fastboot and adb command. But I appreciate the effort to help people in here to recover their phones.

Dear ShiningScias.
Hello, well I guess then, I was on the shoft bricked side?
Thank you for making that clear to me, I then have to apologize, to everybody that I have mislead, with an assumption that was not the correct one.
I misunderstood what the hard brick is, I think probably i had jumped to that conclusion because when I was searching for rooting my phone I came across with so many tutorials and advices not to make any mistake while shifting between roms with ARB or else the outcome will be a hard brick.
Best regards.

Dear yumm91,
Hi, yes I flased my phone via EDL Mode since I had no other option, (hard brick) the system was erased by a terrible mistake and the phone was only opening to fastboot mode, no matter what. And if you have hard bricked device you can not flash it in fast boot mode simply because your computer can not see the phone.
Thus not adb debuging authorization to comunication with the device for reflashing. So only EDL Mode that qualcom put in place for such an awkward situation
At that time the only tools and knoledge I had regarding my newly purchased phone Mi9T was:
A) Flashing through Mi flash tool (which is locked for everyone to use without special account) I found it out afterward.
B) the all in one tool, that I found when I was looking for help in xda forums, which is for unlocked phones, as it states in the main window.
Said that before, I started looking for how to flash it in edl mode.
Nobody new then (a week ago) how to revive, bring back to "life" their phones( Mi9/K20 and Pro variants).
The general idea that was floating around regarding hard bricked devices.
Was the option of having a person with authorized account for flashing, to enter to your computer, and flash it for you,
( after opening the back cover and disconnect the battery, while make jumper between the the special points on the PCB).
To return the phone back to have it repaired, Xiaomi's suggestion.
I tried many times the mi flash tool, even when I was logging in, my xiaomi account said "this computer is bound to your account you can start now", but with no luck.
So Before I take my phone and bring it to a service center, for flashing for 55 euro.
I tried one more ultimate time, and boom success.
From what I know locked phones, can not be hard bricked since the system will not let you roll back, or flash not original xiaomi rom.
I posted the way arround to the Mi flash tool, that I came accross by trying to flash a bricked device , for everybody to overcome the authorization problem.
I am not a developer nor an expert regarding android programming, I just have little experience from previous devices that I messed arround by trial and error.

You haved probably problem with fastboot drivers for your phone. Bcs this tool u used to boot EDL mode is also using fastboot first to boot in EDL so how u boot EDL if u told before that your phone can't be recognised by fastboot on your pc ?
I guarantee u can easily unbrick device with unlocked bootloader using only miflash or using fastboot command on adb. So there is no point to do all steps in description.

---

Wait. If i will unlock bootloader, and for some reason it will fail and brick, it will be bricked on locked bootloader or unlocked?

Is this method works with a GLOBAL image flash to a chinesse K20?
