Problems flashing XiaoMi Mi A1 in EDL mode - Xiaomi Mi A1 Questions & Answers

After a failed attempt to enable a Google Camera HDR+ port, I've found myself unable to boot and with a locked bootloader. I would also be happy if the bootloader could be unlocked, but I have no access to the Android settings and "fastboot oem unlock" refuses to act; and the XiaoMi unlock tool falsely claims that the device is already unlocked "and there is no need to unlock again". So my only hope is flashing a ROM in EDL mode with XiaoMi Flash. Unfortunately, it's easier said than done.
First of all, initially my Win7 64-bit systematically tried to load the wrong Qualcomm driver, namely "Qualcomm HS-USB Diagnostics 900E", which doesn't work. After forcing a driver update (which requires unticking the "Show compatible hardware" box: why??) I finally managed to convince Windows to load the "Qualcomm HS-USB QDLoader 9008". The loading is only achieved if the USB cable is plugged in after a fresh phone reset with Up and Down volume keys both pressed (or, in Fastboot mode, after invoking "fastboot oem fastboot-edl" with fastboot_edl), but that's OK. Then, clicking the "Refresh" button in XiaoMi Flash' window, I see the line mentioning the COM port (COM6 in my case). Unfortunately, if I then press "Flash" the operation ends in error ("[14:09:30 COM6]:sahara read end error with status:9"). The log file reads:
Code:
[14:09:30 COM6]:MiFlash 2016.12.22.0(Release)
[14:09:30 COM6]:[COM6]:start flash.

[14:09:30 COM6]:after:flashSuccess is False set IsUpdate:false set IsDone true
Any idea? Am I using a wrong version of the QDLoader driver (2.1.2.2 25/03/2016) and/or of XiaoMi Flash (2016.12.22.0(Release)), and, if so, which one is known to work with a Mi A1?

i had the same problem i tried to instal gcam but i was usin a costom rom and my phone got bricked, my only hope was EDL mode but i did know how to do it, i just went to the service xiaomi and the fixed i recomend to you do the same, go to xiaomi service.

I do not know if you already tried this procedure, if you have not done it it would be worth giving it a look.

Thank you. I also tried that method ("deep flash engineering cable") but the results were the same: and from what I understand that's just one of the several ways of putting the phone in EDL mode, just like the reset with "Volume Up" and "Volume Down" keys both pressed, the "test point method" (which requires opening the phone), the "fastboot oem reboot-edl" command while the phone is in fastboot mode, or the "adb reboot edl" command while Android is running. My phone does go in EDL mode (which is why the QDLoader drivers gets loaded and Xiaomi Flash duly "sees" the phone); unfortunately something seems to go wrong during the Sahara protocol communication between Xiaomi Flash (through the QDLoader 9008 USB driver) and the phone. I suspect that there is some incompatibility between the Xiaomi Mi A1 EDL software and the particular version of QDLoader driver I used, but I already tried two different versions with the same negative results. If someone here has successfully used this method with a Xiaomi Mi A1, please let me know the version of the QDLoader driver that was used...

I did, in the Hong Kong service centre in Mongkok, but, after testing it, a the technician (not a very smart one IMHO) said that "it can't be turned on and the only solution is to replace the main board", which, as I don't have the original purchase receipt, would cost me HKD 1,000...

Redmi note 3 Pro / Snapdragon 650 edition - Hard brick resurrect

First of all, i have read some similar threads about this, and all advise diffrent solution besides the hardware mod, I have tried for 2 days all methods in Miui forums and none have worked for me except the hardware method.
My Device: Xiaomi Redmi Note 3 Pro / SD version.
State:
-would only show "Mi" logo when powered on.
-Would enter only Fastboot.
- No EDL mode
- No recovery
-bootloader locked
-In this state, you can't flash absolutely nothing with any software. (from fastboot).
Requirements:
- windows 7/ windows 10 x64 edition.
- ONLY LATEST version of miflash, from 2016 onward, so it has the required drivers and methods to work with the phone. (I have tried with older versions and it did not work, i thought there was no hope for my phone).
- one hard bricked Redmi Note 3 Pro
- any fersion of Stable FASTBOOT OFFICIAL rom. (.tgz extension) - I personally used kenzo_global_images_V7.2.3.0.LHOMIDA_20160129.0000.14_5.1_global_c85ba6c524.tgz
- medium disassembly skills,
- a lot of patience,
- minimum set of tools (one small cross screwdriver, 1-2 strong finger nails, good eyesight).
- one microusb cable
HOW TO:
1. uninstall all drivers and software related to the Xiaomi phone. (I ended up reinstalling windows 7 just to be sure all was gone - that is how desperate I became). To be sure this is done correctly, with the phone turned off, connect it to the computer.
Go into device manager, search in com ports, or wherever any drivers are installed for the phone, and uninstall all of them, ticking remove driver files also.
after doing this, hit refresh, and see if any drivers get installed again.
Repeat until there are no drivers installed, and the device will be without a driver.
2. Disconnect the phone and RESTART WINDOWS
3. Disable driver signature verification/enforcement:
a. in windows 7, this is easy: restart windows, hit f8 until a menu pops up where you can choose disable driver signature verification/enforcement.
b. in windows 10, it is a little bit longer, but: http://www.howtogeek.com/167723/how...8.1-so-that-you-can-install-unsigned-drivers/ - Be careful, when choosing the option in the last menu, use F... keys, not number keys.
4. while in windows, in the bottom right corner, there should be a message saying "test mode"
5. install ONLY the LATEST VERSION of Miflash! you may get some messages about driver installation (2 times), allow installation!
6. RESTART WINDOWS
7. Prepare the phone!: I followed the video here, even I did not understand the language: http://choimobile.vn/threads/video-...o-snapdragon-650-fix-download-mode-edl.65098/
- First, I used my nail to open the phone up, just like in the video. It is great that the screen is not glued to the body, there are only some clips holding it in place!
- after opening the cover please be careful - there is a cable connecting the case to the mainboard - the fingerprint sensor.
- after this, unscrew the 7 or 8 screws as in the video.
- unlock the cables as in the video - please be sure not to disconnect all the cables.
- now, first get the antenna plastic cover outside of the way.
- after disconnecting the camera module, I would personally advise you to get the camera out of the way first, as there is a piece of foil glued between the mainboard and the underneath of the camera module (on the display)
- with great care, rise the Mainboard from the display.
- to have better access to the testpoint pins, I turned the Mainboard over the battery.
- now, connect the microusb cable to the phone.
8. connect the phone to the computer.
9. go into device manager and check if there are any devices installed, there should be under ports.... a device called Qualcomm HS-USB Diagnostics 900E.
10. Now comes the tricky part, switching the phone to EDL mode (emercency download)
look on the back of the motherboard of the phone to connect the 2 testpoint pins as in the video. You can use anything to do this. a metal wire, a small scissors, an untied paperclip... You will have to do this while device manager is opened, as you must check it when the driver changes to "qualcomm hs-usb qdloader 9008".
Please be careful when trying to connect the 2 pins not to touch any metal housing, ans this will restart the device each time.
Now, try and try and try until the driver changes to "qualcomm hs-usb qdloader 9008".
11. unzip the rom using 7 zip to a destination of your choosing. I advise as short destination as possible and no spaces used in the folder naming. I unpacked it in C:\rom\
12. Open Miflash
13. As per other many many instructions:
a. click browse - select the folder where you unpacked the rom (for me, c:\rom\)
b. click the arrow next to brows button and select advanced.
c. in the first field, navigate to the folder where the rom was unpacked and select flashall.bat
d. in the third field select prog_emmc_firehose_8976_ddr.mbn from the "images"folder in the folder whre he rom was extracted
e. field 7: rawprogram0.xml and field8: patch0.xml
f. Hit the Refresh button, the device should appear as a com port in the white field of Miflash.
g. just to be sure, tick also "flash all" in the bottom of miflash.
14. Hit the Flash button on Miflash and this should be the last step before powering up your revived Xiaomi Redmi Note 3.
This is what I learned in the past 2-3 days.
Different errors I got during the learning process and what i did to avoid them:
- different problems with drivers not installing correctly or showing different device names - just use the method i pointed out in the beginning to uninstall any driver previously installed on the computer, with the refresh in device manager and than uninstalling all.
- "end of package" error at second 2 while flashing in Miflash - you are using an older or an unsupported version of miflash, just use the latest one.
- not being able to flash anything while in fastboot - if you have a locked bootloader, on redmi note 3 snapdragon version, you simply won't be able to flash anything. end of story. this is the whole purpose of having a locked bootloader.
- trying to go into EDL mode using fastboot comand "fastboot oem eld" - this will not work for a really bricked device as was mine. the only solution is to go through the tespoint pin connection.
i wonder if there's a way not to make trwp locked in the recovery partition, so if someone flashes a factory rom without precaution, twrp will simply get overwritten by factory recovery. Wouldn't that prevent these hard bricks?
btw, nice guide
Please move the thread into guides/tutorial section.
Well, mine was bricked too 2 days ago... even I already unlock the bootloader using the official way.
It happened because I'm on AOSP and I flash Xiaomi.EU ROM from TWRP.
'MI' Logo flashed twice then the phone turns off itself.
It can't boot, can't enter EDL mode. I just can go into fastboot mode. But nothing can be done there because it always says 'device is locked'.
'fastboot oem device-info' also says the phone is on locked state.
Dunno why this happen, I think its because I play with the unlock bootloader toggle on previous MIUI and AOSP ROM.
After countless of times trying to get into EDL, I give up.
Device manager always show "QCom HS-USB Diagnostic 900E" instead of "QCom HS-USB QLoader 9008"
Finally I try the official Mi Unlock software, re-unlock success and BAM... Phone boots again into system. lol...
This makes me think the bricked problem can prevented/solved to by:
- At least bind a Xiaomi Account to your phone once when using official ROM (recommended China Dev ROM)
- Use that account to apply for the unlock, and when you got the phone bricked/relocked, you can re-unlock it using official way to revive the phone
Now is possible unbrick without disassembly:

please read through all the thread, don't just throw in a link. the method mentioned by you will not work on some bricked devices, including mine. this did not work for me, so I ended up disassembling the phone.

I also applied for an unlock code, but this takes up to 15 days, and I have the phone for only 3 days . I could not wait for the code, I had to do something to revive it.

I doubt they will have much variance from xiaomi phone to phone to make it easy for factory / repair centers to fix many models... (I could be wrong though), other brands are probably different.
Well you can enter edl mode from fastboot via this simple tool
http://forum.xda-developers.com/and.../guide-how-to-reboot-to-edl-fastboot-t3394292
And then you can flash any miui .tgz based rom and resurrect.
I hard bricked my Device last night and resurrected
PS : you must have the MiPcSuit installed

Quick addition: if you're using Virtual Box, like me (on a mac), you need to enable USB 2.0 on the virtual machine. On Virtual Box, this means you have to add an extension pack. This might save you 48hrs, like it cost me

[Solved] A2017G totally Bricked

First of all, i live in Bangladesh. I asked a relative of mine who lives in Sweden to buy me this phone. So, there is no way for me to send this phone back to ZTE.
Now let me explain how i got into this huge mess. I installed twrp successfully using this post - https://forum.xda-developers.com/axon-7/how-to/guide-install-twrp-unlock-bl-flash-t3517379
i only followed part A of this post. Then i needed to root. so i tried to flash supersu 2.79 first but failed. Then i tried to flash supersu 2.65 as someone commented that they failed with 2.79 but succeeded with 2.65. However, after flashing supersu 2.65 i soft bricked my phone. i could still access twrp 3.0.2. After a while, i downloaded b08 update.zip and tried to flash it through twrp but failed. then i saw this post - https://forum.xda-developers.com/axon-7/how-to/guide-root-xposed-safetynet-stock-rom-t3530906
and this post - https://forum.xda-developers.com/axon-7/development/recovery-official-twrp-zte-axon-7-t3515715
And tried to update twrp to 3.03. which then hard bricked my phone. now i cannot access anything. when i try to start my phone it shows the zte logo for a second and the whole screen goes blank with the red led.
same thing happens with volume up+power and volume down+power. And there is no way to turn the phone off. So, i waited a whole day for the phone to empty it's battery and tried to boot to edl mode using volume up+down but Qualcomm HS-USB QDLoader does not appear. The only thing i can get to connecting to my computer is handset diagnostic interface.
Now only a brilliant dev can help me. So can someone PLEASE Help me.
Also i've found this post is very similar to my problem https://forum.xda-developers.com/axon-7/help/bricked-a2017g-b03-help-please-t3487635

Why can't you boot into EDL mode?
That's strange to me...
Did you try another computer to see if it pops up there?
Then try to reflash recovery if you can...

yes i have. but in the device manager, instead of Qualcomm HS-USB QDLoader, Handset Diagnostic Interface appears.
Furthermore, computers does not recognize any adb device when i connect my axon 7
what do i do???
Edit: when i uninstall Handset Diagnostic Interface from device manager and then connect my phone with both volume keys pressed, at first qusb_bulk appears but after automatic installation of hardware software it's Handset Diagnostic Interface all over again
Well I did some Google'ing for you and I guess the things in these threads might be your best bet:

However all these methods are not tested with the Axon 7 and seem pretty risky to me...
If I were you I'd send the phone back to Sweden so the relative can send it back to ZTE.
I'm not sure if this falls under the ZTE warranty stuff so they might charge you a bit; anyhow it's still the better option than throwing this phone away I'd say.
I don't think I can really help you here, sorry :s

I don't think your phone is in such a dire condition. I was contacted by @raystef66 only last night. He made the same mistake as you did, trying to flash SuperSU via TWRP on a locked bootloader phone. However, he didn't take all steps you took.
If I were you, I'd try to somehow prevent the PC from automatically installing the ZTE DFU (Diagnostics) driver. You say the device appears to be in EDL mode when you connect it (QUSB_BULK) and then it installs new drivers. Can you somehow cancel that process?
Here's a microsoft guide on how to prevent your PC from automatically installing drivers. Maybe try that and reconnect your device. It might get recognised as QUSB_BULK and then you can restore your stock recovery via the Axon7tool? If you can do that, it shouldn't be a lost cause?
Send me a PM with your Hangouts, let's see if I can help.

You can make Windows to use the right driver so you will be able to use axon7tool. So if you have problems connecting to your phone as QUSB_BULK, download Zadig to your computer and replace your drivers with WinUSB ones. Open Zadig tool, go to Options and activate List all devices. Then select QUSB_BULK in the drop down control at the top and WinUSB in the lower control. Then click on the button to replace the driver. After this, QUSB_BULK should appear in the Device manager and you should be able to execute axon7tool and flash TWRP 3.0.2-2 signed again and continue with the unlock procedure.
If you have the QUSB_BULK with a warning icon then you need to install the Qualcomm usb driver.
All the answers on how to return to a working state or not falling into a soft brick like yours were just in the thread of the guide you didn't complete. Devices with the Qualcomm Snapdragon 820 are unbrickable. So do not panic, and read the whole thread [GUIDE] [A2017G] Install TWRP, Unlock BL, Flash Custom ROM.

My QUSB_BULK is not with a warning sign. And i have already used Zadig.
At first, i couldn't get past DFU mode. But after following @Controllerboy instructions i am able to get QUSB_BULK in my device manager. But it's all the same.
For axon7tool to work the computer has to first recognize my a2017g as a adb device. That's where the problem is. My phone is not being recognized as an adb device. When i use adb devices on cmd there is no listed device. I have already tried this with other computers but the results are the same.

EDL mode has nothing to do with adb!!!!! adb only connects to recovery or a booted system. fastboot connects to bootloader, and Axon7tool communicates with the EDL bootstrap. In order to use Axon7tool (to flash or backup boot or recovery partitions) your computer has to detect your device as QUSB_BULK. Obviously in that mode adb or fastboot will not find your device in a compatible state.
What can you do?
1. read the whole thread, not just the opening post. As advised.
2. Use Axon7tool to flash the same TWRP 3.0.2-2 you flashed before. It is signed, so the bootloader detects it as a valid ZTE image even when the bootloader is still locked.
3. Unlock your A2017G phone.
4. enjoy flashing and reflashing all the multiple roms, patches, etc.

Sir, i don't u understand my problem properly. Let me give u a thorough description.
When i press and hold the power button the phone vibrates shows ZTE logo for less than a second then the screen turns off and the LED turns red.
When i press volume up+power same thing happens.
When i press volume down+power same thing.
And i cannot power off my phone no matter what i do it always stays at that state until the battery is empty.
Then if i press volume up+down at the same time and insert usb red led turn on.
And when i insert the usb in any of these states only one thing appears on my device manager is "Handset Diagnostic Interface (DFU) (ComX)"
But if i Uninstall Handset Diagnostic Interface (DFU) (ComX) from device manager and disable automatic driver installation through group policy then QUSB_BULK appears with a yellow sign.
If i use Zadig to install winusb driver then the yellow sign disappears.
U r telling me to read the whole thread. I have done so. But in DFU mode adb devices command doesn't list any device. If my computer doesn't see my device as an adb device how can i do anything.
I have also tried to use axon7tool -w recovery command since my device is in qusb_bulk mode. But cmd says no device detected.
2017 DFU mode investigation
Bricked A2017G
These posts have given me a big scare. Since no one has been able to recover from the same condition that i am in right now.
That's why i'm asking the help of experts. Please help me.
I have also came to a conclusion myself that if a tool like this Flashing recovery or this ZTE Open Download Mode or maybe this [TOOL][ALPHA] ZTE Warp 4G Unbrick Tool is not developed then this particular Qualcomm Phone is Brickable.
I am saying this because after a good amount of googling i came to know that when qualcomm phones are bricked it goes into emergency download mode which shows as "Qualcomm HS-USB QDLoader 9008" or "Qualcomm HS-USB QDLoader 9006" on device manager. And there are a lot of guides to unbrick from that state. But only old ZTE devices go into "Handset Diagnostic Interface (DFU) (ComX)" mode aka DFU mode.
And there are different guides for different models.
This is why i am panicking and asking for the help of experts. If there was a guide to recover from this state this post wouldn't exist. So if u can, please help.
And sorry for my english, i tried my best.

Thank you for the link. But i tried this miflash tools weeks ago.
Here is the full guide in my opinion for the mi flash tool.
http://www.androidbrick.com/unbrick...-you-have-the-right-kind-of-rom-qhsusb_dload/
Unfortunately, the A2017G does not have 9008 port. It has ZTE's own Handset Diagnostic Interface (DFU) (ComX) for which i need the latest version of ZTE firmware flasher. At the moment only ZTE have this. So, my bricked phone is a lost cause.

Chinese Axon 7 is not seen in ADB or MiFlash..Bricked??

After installing twrp on my chinese axon 7 latest B16 I rebooted accidentally and now my phone gets stuck on the the ZTE logo.
I cant enter recovery as when I press volume up + power, it reboots a couple of times with the zte logo and nothing else.
Also when entering EDL mode the only thing my PC is showing in device manager is "Handset Diagnostic Interface(DFU) (COM6)". Before it was showing as "Qualcomm HS-USB QDLoader 9008" but no more, even after multiple reboots and installing the qualcomm drivers again.
Before when running "adb devices" in the CLI I would see my device but now nothing. and running adb reboot edl shows error: no devices/emulators found.
Also tried MiFlash but when I hit refresh I dont even see COM in the list, its just blank.
Does anyone have any suggestions?
as I tried the below guide but get stuck as my device is never picked up by ADB or MiFlash

But I see it involves me opening the device which I am trying to avoid as a last resort.
I just sent the seller from Ali-express to see if they will replace it.
Never actually told them that I was tinkering with it.

I had to follow the guide, and it fixed my phone, so be assured that you can fix it if they send it back
It seems I got really luck as putting my phone in Factory test mode made device manager finally show "Qualcomm HS-USB QDLoader 9008" which I was then led MiFlash in detecting it.
I was then able to flash Stock B13 and from there unlock the bootloader, flash twrp and root.

Usually you can't enter Factory Test Mode when on a DFU brick. The known procedure to do that is to discharge the phone, then put it into FTM somehow and then using ADB to get to EDL. It's really weird that you've been able to pull that off that way
Could you tell us how you got into FTM? Just by vol down and power? It would be a nice addition to the brick guide, before attempting to take the phone apart
Yeah, it was just by power + volume down.

Softbricked axon 7, need help !

Hey guys, I have a A2017 axon 7, and I tried to upgrade from Marshmalow to nougat by flashing the B04 update from TWRP. I have now the factory recovery mode, and when I try to go in fastboot, it tries to launch the bootloader( which just tells me that my device software cannot be checked for corruption and that I need to lock my bootloader). When I try to boot normally it stays on the same "bootloader screen" and tells me to press the start button which makes the phone display the linux logo.... I'm a bit lost, I'm on ArchLinux could you pls help me ?
Thx !

Well, you should use MiFlash and install the stock system through EDL. The problem is that MiFlash is for Windows x64. if you could get a win10 x64 pc, you could fix it in a minute.
Or get to the recovery if you can, and flash Nougat again but via an SD card. But maybe you won't be able to get to the recovery mode

When I press any combination it always turn on for 1 sec and then the screen turns off again but it still GOT recognized as QUSB Bulk. After I installed MiFlash the device is recognized as QDLOADER 9008. I didn't flash anything and I don't kno how to unbrick my device now .

How did you relock the bootloader? If you used a guide, you should have found a warning, and if you used axon7toolkit a message should've popped up.
You messed up. Real bad. You are probably on DFU mode, and the only ways to get out of there are:
-discharge the battery completely and try to enter FTM mode (i think you have to do that while it is connected to a PC), I think it was with volume down + power. this method works for very few people. If you enter ftm mode, issue 'adb reboot edl' and use MiFlash right away with a FULL_EDL package
-use the 4th category brick repair manual (disassemble the phone, short some pins)

I think DFU Mode is when I get recognized as ZTE Handset diagnostic .... according to this guide : https://forum.xda-developers.com/axon-7/how-to/a2017-4th-category-brick-repair-manual-t3585898) It's a2017 but still.
"Axon 7 restore manual from bricked conditions when only ZTE Handset Diagnostic Interface(DFU) (COM...) mode is detected"
But I get recognized as QDloader 9008 and miflash also recognizes it as com10 or something.

it's not necessarily like that. DFU mode is just a mode in which the phone can be. Sometimes Windows just installs the QDLoader driver even though it's not EDL. and if you tried miflash and it didn't work, then it's most probably that.
There's a way to check. If you go to Properties, there should be a number that identifies the mode. if you google it and 'dfu interface' appears, then you are dfu-bricked
But if you locked the bootloader without being fully stock then it's most probably dfu bricked anyways
Again, how did you lock the bootloader?
I don't actually know if I really locked the bottloader.
So, I had unlocked bootloader and twrp. I just bootet into the bootloader, typed "fastboot oem lock" in adb and it said OK on the PC.
But on the phone it never asked me if I want to lock it or anything. And I never said MiFlash isn't working. It recognizes my phone but i judt didn't TRY to flash anything because I didn't want to make the situation even worse perhaps

Lol it doesn't ask you if you want to lock it, that's the point with bootloader mode. there's no system, no UI, and you make stuff via commands.
This is why you shouldn't even attempt this kind of stuff without knowing how it works. At least if you had used axon7toolkit, it would've told you not to.
Find a FULL_EDL package for your model. If you have an A2017, simply use this one:
https://androidfilehost.com/?fid=817550096634790942
or
https://mega.nz/#!JqwEUDCa!lW3NDaBNbmMxhtw6XajspHBJaaEmLC8uNvMZS5ww0EQ
(they are the same file)
Unzip it, leave the folder somewhere handy, put the phone in what you believe is EDL, open MiFlash and select the folder, and flash

Okay let me tell you this real straight. I have done this. I have the G packages, I just thought you were the op for some reason. Look at the back of the phone and confirm whether you have an A2017G or an A2017 just in case, or you might mess up even more, as hard as that can be.
at any rate, your fears are all dumbfounded, because in the situation that you are in, you have 3 options:
a) disregard all the help that i'm trying to give you, even though I have already done the process; and keep your brick on a shelf.
b) search on google or xda yourself, then do the process, without bothering here with your lack of trust
c) follow my advice and do the damn process
Whichever option you choose, I'm gonna leave the package here:

Again, I HAVE FOLLOWED THE 4TH CATEGORY BRICK REPAIR GUIDE AND FIXED MY G. I flashed stuff through EDL at least 10 times. And there wouldn't be a bunch of EDL packages for the G if they had a 100% chance of bricking your phone
So. If you decide to do this, turn your phone off. connect the USB cable to the PC but not the phone. Hold both volume buttons (but not the power button) and insert the USB cable at the same time. Then fire up MiFlash and try to flash the file (you have to unzip the folder, then select the folder on miflash, then flash. Here 2 things may happen:
a) it flashes and you can just go bother someone else
b) it doesn't and you have to follow the 4th category brick repair guide
Simple as that. if it fails, you might want to check if the 'Qualcomm HS-USB QDLoader 9008' is actually EDL mode or DFU mode, so you can do that by going to properties and checking some device identifier number on google (haven't done that, i just read that it can be done somewhere here).

Ultra Bricked Mi 9t

Hi !
I need your help please, my phone doesn't want to enter in fastboot mode.
* Black Screen 100%
* If I press power button after 4 or 5 seconds it does a vibration
* Power button + Volume Up (looks llike it turn off the phone)
* Power button + Volume Down (looks like it want to enter in fastboot mode)
When my phone is connected to the PC it is recognized as: Unknown USB Device ( Device Descriptor Request Failed )
Blue LED always turned on (once the phone is recognized as Unknown)
The first that I tought when I saw the message ( Unknown USB Device ) was... ok this phone is really hard bricked and is needing a Test Point.
I did the Test point and my phone still giving the same message.
I tried different USB ports and same problem. (USB ports are ok)
I didn't tried a different USB cable and it has higher probabilities that my USB could be damaged. because (Device Descriptor Failed) is a problem from faulty USB ports or Cable.
But my USB Cable looks like new and it was used few times... also I tried moving a bit the connectors to see if it does something but no.. nothing happened.
The USB Port from the phone is like new. (I opened the phone)
If you have experience with the message: "Unknown USB Device (Descriptor Request Failed)
Please give me some help !
Hi !
Looks like the real problem was from drivers. Finally I installed the K20 drivers from this site : https://gsmusbdriver.com/xiaomi-redmi-k20
Then I did the test point
1) I Pressed power button with the test point
2) I heard a vibration
3) I released the power button but I continued with the test point
4) Voila the drivers were installed correctly and now my phone is recognized as: " Qualcomm HS-USB QDLoader 9008 "
EDITED:
If you are experiencing in device manager: USB Device Unknown Descriptor Request Failed maybe could be faulty USB port or cable. In my case was the cable. Now is working perfectly everything with a new USB Cable.
Now I'm trying to flash the phone using " Mi Flash Tool "
I downloaded the stock rom from Xiaomi site.. By the way my phone is with bootloader locked and is not rooted.
I pressed Flash button and the program asked for EDL Authentication. "I Created a new account" Logged suscessfull and then:
"Error" Root Element is missing.
WTF? why xiaomi is asking me for a rooted phone??
Please Help, any Idea about what I'm doing wrong?

I think EDL is a special account authorised by Xiaomi.

Yeah u need a EDL Flash and for that an EDL verified Account, which u can't get anymore from xiaomi ..
you have to find someone who are willing to do it for you. Usually you have to pay for it .. around $50.
or try this

Did you try this :
- Download the stock ROM from xiaomi website, no tools needed, just adb and fastboot installed
- Extract the rom to a folder and launch "flash_all.bat" with admin.
- If you encounter an issue try it with another OS (try this if you don't want to install another OS : https://forum.xda-developers.com/an.../live-iso-adb-fastboot-driver-issues-t3526755)
Tell us if it works.

MTP USB Device
Please help What I can do to flash my phone¿? it is fastboot mode right? in fastboot mode I can do flash without an account authenticated righT?
Im trying to use Mi Flash TOOL again and Im getting this message:
fed4e139]:info1:$for /F "tokens=2 delims=: " %i in ('fastboot -s fed4e139 getvar anti 2>&1 | findstr /r /c:"anti:"') do (set version=%i )
Im using the latest rom for the K20 global phone but dont know why it is stuck with that message and STATUS: Flashing but it doesnt do any progress.
What Can I do?? is ok MTP USB Device? is that the correct drivers to do a flash in fastboot mode??

Does the phone display the fastboot logo? If it does, then you have to remove some lines from the flash_all.bat file. The first ones where it says something about getvar product.
you can fastboot and just push it in cmd if fastboot active. I bever use bat files, because its only 2 lines to flash

This is what happened:
I was watching my phone recognized as MTP USB Device and I tought yeah! my luck is from my side! now will be possible to flash my pohne in fastboot mode !!
I tried a lot of times with FLASH TOOL and it never passed from:
fed4e139]:info1:$for /F "tokens=2 delims=: " %i in ('fastboot -s fed4e139 getvar anti 2>&1 | findstr /r /c:"anti:"') do (set version=%i )
then I tried in adb: "adb devices" but I never saw my device connected even with MTP USB Device driver activated in Device Manager.
so I tried anyway to use the flash_all.bat and same message received "getvar anti" bla bla..
I never deleted the lines about getvar from the file "flash_all.bat" because now my phone it is exactly as in the begin....
Now the PC doesn't want to recognize the phone... again the same ****.. " USB Device Unknown (Descriptor Request Failed) "
I did the test point and the same crap... the phone doesn't want to be recognized USB Unknown...
Come on... I can't believe it... I had decided to pay for the service flash with EDL authentication in the next week and now I can't even make it boot in EDL... exactly as in the begin I'm.... the phone it is with the same sympthoms.. :crying:
EDITED:
Now the Phone was recognized by the PC again as: MTP USB Device but with yellow sign..
I disconnected, reconnected the cable and nothing yellow sign.
I did the test point and boom Im back again into the same ****... USB UNknown (Descriptor Request Failed)
what the **** is happening?? Im not so sure how the phone can be recognized as MTP USB Device but i guess that it is fastboot mode. and that is what I want to try the solution from the first post of this threads.
or the second solution understand what I have to do to put the phone into EDL. Because I did a lot of times with sucess at the begin and now Im doing exactly the same and nothing. it doesnt want to work.
Looks like drivers problem?

Most likely. I had similar issues with a rn7. Try it on another pc. I had issues getting the phone recognized in w10, then I switched to an old laptop I had with w7. Didn't install drivers, didn't do anything, windows installed it's driver and the phone was there. So it may be a issue with your OS. And again, delete the first two lines from the flash_all.bat to get over that error.
Edit: The flashing with MiFlash tool will only work if you see the fastboot logo on your phone. If the phone is seen in cmd after you type "fastboot devices".

Thanks for the answer, I have the notebook with two windows.
W10 64 bits and W7 32 Bits.
Same problem in both, don't know how can be driver problem, because I installed exactly the correct versión. (I know that is the correct because I could do the test point correctly two days ago) and it was recognized as: "Qualcomm HS-USB QDloader 9008 (COM4)" But today it doesnt want to recognize anymore the phone. Only "USB Device Unknown (Descriptor Request Failed)"
So hard is to make it boot in EDL mode? i saw the picture for test point (k20 xiaomi) and it is really easy. but PC recognize the phone as Unkonwn after test point. The first day that I did the test point happened the same ****.. I was hours and hours trying to make it work.. till I installed the correct drivers. and now is happening the same.. hours and hours trying to boot in EDL and using the same drivers, same process, but nothing.
Except at 3:00 pm dont know how the phone was recognized as MTP USB Device (with yellow sign error in device manager) so i did again the test point and boom.. USB Unknown again...
If I press Power button + volume up the phone looks like turn off and instantly I do the connection from usb cable and nothing appears in device manager but 2 mins or 3 mins later the phone is recognized as unknown and blue led light start to blink every 1 second.
If i do the test point it is recognized instantly as Unknown but there isnt any blue led light blinking.
I tried test point without battery and same. problem.. I tried to do the test point without release the pins so fast.. and same problem I tried releasing fast.. slow... etc
I tried to removed the battery and press power button to drain all the energy from board.
I tried to charging battery with power supply and the blue led light is turned on after 2 mins and it continue on over 10 or 15 mins then it is off the blue light. I used a tester to see the voltage from battery and is ok looks like it is full of charge.
If I do the EDL Cable could it be different? or is the same as test point?
Thanks for your help guys you are good people!
Have you tried with Linux? With the distribution I mentioned?

Hi! Thanks! Yes I tried to flash in fastboot mode. I did adb devices command and it was recognized ok.
But when I tried to flash_all.bat it gave me error: "bootloader locked" looks like I need the bootloader unlocked to flash via ADB in fastboot mode.
what I want to try is like a bug in xiaomi mi flash tool. The first time that I tried to use it. I made a new account and I received a message like:
"Logged Suscessfull"
"Your Account was blind to this PC. Now you can start the process"
Then I received an error like "no root permission" or something like that (maybe was because the usb cable was bad)
Looks like the xiaomi flash tool passed the EDL Authentication. because now each time that Im trying to use MI TOOL this is the message that Im getting.
"Logged Sucessfull"
You are not authorized for this operation

Ok, suddenly you can not reinstall via all these methods because your bootloader is locked... Have you tried asking a member here if anyone has an EDL account (a real haha) ?
