Bought a used Mi A2, how do I proceed?

Just bought a used Mi A2 from a guy. He dosent know what Android version it is and its probably locked. Ive been out of the Android game for many years now, but managed to install ADB and Fastboot on my Mac.
The problem is that the device is boot looping on the Android One logo. Managed to get into Fastboot, and the device shows up in ./fastboot devices. Tried to run this quickie, but only get a "Device is already locked!" message.
So please, point me in the right direction as both the Internet and forums here are loaded with information.
In the end I would like to have a custom ROM, LinageOS or something maybe.
Thanks in advance.

1st try to reboot numerously with external power On (if there is a valid Android One ROM in one of two slots, sooner or later bootloader is to boot into this valid ROM).
In case phone does not have a valid Android One ROM, then next step would be MiFlash'ing via EDL (search for TestPoint Guide in "Guides, ....")

Like just boot loop it or hold the power to reboot?
I think the EDL pinout opiton is the way to go after some searching, but Im in a desperate need of a torx driver..

In Fastboot the device only displays "fastboot", no options what so ever. Tried powering on the device without power cable 20 times and no go, boot looped on external power for about 10 minutes, no go.

Sure there is no options in fastboot mode, "enter fastboot mode and reboot" means just that -> enter fastboot mode and then reboot (either long-pressing power on phone or with "fastboot reboot" command from PC.
I gave you clues, please don't tease me to dictate step-by-step, I do not own your phone.

Ye sure, thats fine mate
did 'fastboot reboot' about 10 times now and still no go.
Found a Xiaomitool for macOS that has an option for "unbrick my device", but need the previous owners Mi account probably, so Ive asked if he did have a Mi account.

Most probably that's a false path, as MiFlash, Mi Account, Mi Unlock and other such stuff are for owners of "native" Xiaomi MIUI phones, while Mi A2 boarding Android One is regarded as stepchild. Better search for Android One solutions (in these forums of in developer.android.com)

Maybe. I think the phone is stock, just bricked after some update.
Just need to get the bloody torx driver!
EDIT: when I do manage to find a tiny tiny torx driver and open up the phone, disconnect the battery a bit, connect it back up, and its time to connect the two EDL pins, how long do I hold? USB cable plugged in?

Yes I have same issue, I dont understand, why Xiaomi dont do anything with this ridiculous problem, I dont login with mi account because no paid attention to that, and when I install this update the phone get in bootloop

Disclamer: Have not done it myself, but according to numerous sources the needed Steps (here with Windows PC) are:
1. Open (partially disassemble) Phone to reach 2 contact Test Point spots
2. Connect stock USB cable to USB2.x port on MB of PC, but not to phone, start Device Manager (to see that no USB-phone-related devices are connected and later to see that phone will be connected in EDL)
3. Download desired stock fastboot ROM https://forum.xda-developers.com/mi-a2/how-to/fastboot-xiaomi-mi-a2-fastboot-images-t3824849 and MiFlash, start MiFlash selecting ROM
4. Span the two contacts with something metal and in this state connect USB cable to phone; Device Manager must show newly connected device detected, then contacts may be open
5. Press "Refresh" in MiFlash, same new device must be displayed
6. MiFlash -> clean all, MiFlash -> flash
7. Assemble phone back and reboot
MHO Notes:
a. when EDL/TestPoint method was forced due to soft-bricking, after unbricking it is better to: (1) fully unlock phone and (2) clean-reflash stock ROM via fasboot
(Reason: this particular specimen is subject to OTA soft -bricking)
b. if EDL/TestPoint method fails with Pie (10.0.17.0 or 10.0.2.0), retry using Oreo 9.6.17.0 or 9.6.9.0.

Xiaomi is just repacking Google's Android One updates, and, obviously, does not spend much money for testing OTAs (as AndroidOne phones are not their main market items). From the other hand, Google's Android One A/B Slots feature was developed for so called friction-less ( muhaha ) reverting to previously working ROM when updated ROM fails to boot. So, an Android One phone bootlooping after OTA MUST reboot to previous version of ROM sooner or later (supposed to be 7 retries), sure if phone is not compromised / tampered by previous user actions.

Managed to get hold of a torx set - phone is now open, battery disconncted. USB-C cable ready (dont have USB-A-C, only USB-C-C). Installed MiFlashTool on my PC and tried to get hold of the drivers. MIFlash is giving me a hard time whineing about drivers. Giving me a erorr message, something about JIT-debugging. Only got it in norwegian.
Edit: managed to flash the stock ROM I think. Fuzzed around a bit with the qualcom driver. Now I have a white screen with a rainbow passing over it..
Edit 2: and we're there! MIUI is in - now time to get rid of it!
Edit 3: think I managed to flash TWRP now - do I need root? Can I just flash a Pixelexperience ROM now or do I need to do something else? Used the Android 9 fastboot image earlier, if that has anyting to do with anything.

[OPN100][OOS 81AA/83BA] Unbrick tool to restore your device to OxygenOS

Disclaimer: By attempting any of the processes listed in this thread you accept full responsibility for your actions. I will not be held responsible if your device stops working, catches fire, or turns into a hipster and claims to have been modified before it was cool.
Hi everyone, similar to the previous threads for
OP3, OP3T, OP5, OP5T, OP6, OP6T, OP7, OP7PRO, regular OP7T, T-Mobile OP7T, regular OP7TPRO, T-Mobile OP7TPro 5G, regular OP8, T-Mobile OP8, Verizon OP8, Visible OP8, OP8Pro, OP Nord, regular OP8T, T-Mobile OP8T and Nord N10 5G here are the EDL packages (also known as MSM tools or unbrick tools) that can revive a bricked OnePlus Nord N100.
You should be able to rollback your phone to a previous release of OOS with them if for some reason you want to go back to an older firmware
Please note that on N10 crossflashing regional builds is no longer possible by EDL, flash is tied to device project ID. I therefore expect same to happen on N100. For reference EU devices project ID is 20883 while international devices project ID is 20881.
BE81AA tools (global firmware):
ANDROID 10:
OOS 10.5.3
OOS 10.5.5
Mirror for first and last MSMs: https://onepluscommunityserver.com/
BE83BA tools (european firmware):
ANDROID 10:
OOS 10.5.2
OOS 10.5.6
OOS 10.5.7
Mirror for first and last MSMs: https://onepluscommunityserver.com/
Instructions:
Launch MsmDownloadTool V4.0.exe.
On the login prompt select "Other" in the dropdown menu and click on Next.
Wait a few seconds until main window shows up.
Press Start button so that it waits for your device to be connected
Power off your device
Maintain volume up and down buttons to get into Qualcomm EDL mode.
Plug your device to your computer.
Should you not manage to do that and have adb access, you can use adb reboot edl instead
Wait ~300 seconds.
Enjoy your brand new device.
FAQ:
Does this work on Mac or on Linux?
Unfortunately no, tool is Windows only. You should need at least Windows 7.
Why is my antivirus freaking out when unzipping the archive or running the tool?
In an effort to protect reverse engineering from being done (and by extension prevent conversion process like it was done on 6T and 7Pro), OnePlus now use VM Protect V3 in their MSM tools. As this tries to detect debug environment, this is seen as malicious behaviour by some antivirus.
How can I check my device project ID?
Use getprop ro.boot.project_name. This however involve having ADB access or access to OxygenOS to use Termux or whatever terminal emulator you prefer.
My device isn't detected
Go to device manager and make sure your phone shows up as QDLOADER 9008.
If it shows up as QHUSB_BULK, it means Qualcomm driver wasn't installed automatically by Windows Update. Download the latest one from Microsoft website at http://download.windowsupdate.com/c..._fba473728483260906ba044af3c063e309e6259d.cab (source https://www.catalog.update.microsof...updateid=8ee52ba0-bdef-4009-88cf-335a678dd67a ) and install it manually by right clicking on QHUSB_BULK and selecting "Update driver software" and "Browse my computer for driver software" to where you downloaded CAB file.
If you can't get into EDL mode by hardware keys, you may use adb reboot edl (will require your phone to still have ADB access)
MSM tool is stuck on "Param pre-processing"
Ensure you're using the Qualcomm drivers linked above.
MSM tool is stuck on "Sahara communication failed"
Unplug your phone, get in fastboot mode, turn off phone, wait 15 secondes and get back in Qualcomm EDL mode. You can also try using a USB 2.0 port instead of a 3.0 one.
What is SMT Download mode?
Just don't try to unlock that mode, it will wipe your IMEI and your Widevine certificate if you use it.
How can I fix "SMT config not found" error?

Worked great, thank you! Just one click and the device is back to life. Awesome!

Added MSM tool for global build (10.5.3 BE81AA).

So basically you can't flash convert a branded N100 to global software?

Correct, you can't do that with this tool.
However, OnePlus 8 and 8T T-Mobile versions users have been able to flash global software via fastbootd, so if you're lucky enough same may eventually work for N100.

Do you happen to have the Metro branded MSM tool?

Fyi you don't need latest version to unbrick your device, I just post them for the convenience of restoring to a newer build

So I've been trying to root my device and bricked it by using a process that won't work on my HD1907 T-Mobile Variant. Tried a few different methods and finally was able to get ADB/Fastboot to recognize my device as an "Android Device" by installing the OnePlus drivers for my phone. Well, now it's not working at all. Can't turn off the phone to get it into EDL since it just automatically boots up on it's own, but I can get it back into Fastboot mode. What sux is that I can't seem to get ADB to recognize the device anymore. Also, I haven't been able to use this method since my device shows up in Device Manager as an "Android Device", not the "QHUSB_BULK" that you mentioned in the post. Any tips on getting this method to work? Should I be able to just uninstall the OnePlus drivers and Install the Qualcomm drivers instead? Is there a way to get ADB to recognize my device and then try to flash a stock OS to the device that way?
Please, any advice would really be greatly appreciated.

Thanks, you are a lifesaver! I got myself into a weird position when trying to install Magisk (flashed the wrong boot.img) and this saved me. I got my phone from Amazon (listed as "OnePlus Nord N100 Midnight Frost Unlocked Smartphone, 4GB+64GB, US Version, Model BE2011") and although it was not the T Mobile variant, the pre-installed image lacked the ability to flash a local update (the gear icon was absent in settings -> system -> system updates). Now I have flashed stock Oxygen OS and all is well. As a side question, any clue what kind of weird build it may have shipped with?

can someone commen msmdownloader for realme x50 pro i downloaded other and they jist down wprk.

is it good for model BE2013?

THIS SAVED ME!
I just bought Nord N100 BE2011 from Best Buy (in California US)
I made the same mistake of extracting the updated boot.img 10.5.7 and patching it with Magisk without updating the rest of the system first. So the Boot partition was updated to 10.5.7 while the Oxygen OS and other modules were still on the stock 10.5.3
While the phone was rooted and I was able to install apps and google play etc.. the Phone and Voicemail Functions died with UI Error (SOFT BRICK)
This MSM Tool worked,
I did as the OP says, Download the File above (2.4 gb)
I downloaded the qualcomm drivers first from https://gsmusbdrivers.com/download/qualcomm-hs-usb-qdloader-9008-driver-64-bit-windows/
then boot to edl using adb command:
adb reboot edl
Check to see if phone shows up in device manager as QDLOADER 9008. It is under COM ports
Then unplug the phone leaving it in EDL mode and run the MSM tool
when executing the MSM application it will prompt for login select: "other" from drop down
once the MSM program shows up plug in the phone
It should indicate that it is connected
press start.
On first attempt i received Error and followed the OP:
MSM tool is stuck on "Sahara communication failed"
Unplug your phone, get in fastboot mode, turn off phone, wait 15 secondes and get back in Qualcomm EDL mode. You can also try using a USB 2.0 port instead of a 3.0 one.
(to get it out of edl mode and into fastboot hold power and vol-up)
This worked and the download took 5 minutes.
Phone rebooted to factory settings (after being bricked) and I can receive calls
Cheers,
Alex

Hi,
Can I use this tool for Locked by Metro phone?

I received the Android 11 update and Wifi stopped working perfectly with constant drops. My version is EU, so I used this tutorial to revert to Adroid 10 and Global, and it worked perfectly.

Hi, could you add this unbrick tool for the oneplus nord ce 5G ? thanks

Power off your device, you will need to do the bypass again. Check your USB Cable, there might be a disconnection. If not, start from 3rd step and make sure you did everything right.
Spoiler: FOR PEOPLE WHO WANT TO DOWNGRADE AND FOR PEOPLE WHO WERE ON EU VERSION
So, welcome to hell(!).
For people who want to downgrade:
If you want to downgrade to any version you would like, just use the B23 file as it is the oldest ofp file i could find for extracting process. If you were on EU version before (Any version starting with A) download ozip from here(for EU) , here(for Global) and manually flash from Realme UI recovery and format your data. Your device will be back at A.XY firmware with EU features (No heytap, no ads, no theme store, no bloatware) you had before.
For people on EU who want to unbrick:
So, you can use any version starting with B and it should work. It works in my case, i was on A.48, i flashed B53 and over that flashed B23. No probs at all. If you want to return to EU rom (starting with A) download ozip from here and manually flash from Realme UI recovery and format your data. Your device will be back at A.XY firmware with EU features (No heytap, no ads, no theme store, no bloatware) you had before.

Hello! I wasn't able to find factory package (ofp) files for any version that makes sense for versions starting with A. (EU). There are A11 and A08 which according to update trackers, did never exist and the A.11 package is %50 larger than all the other files weirdly. I have contacted owner of some sites that do upload files like these and they asked for money. If it's a resonable price i will get it, decrypt it and upload here! If you were able to find any versions starting with A, feel free to message me on telegram (@ctivity) or email me!

Hi, it gives an error when I do unbrick with a different version, when my phone was brick the version was A34.

Hello again. According to the site you have just sent, A.11 is the first update to EU version. I was thinking it was a mistakenly uploaded file, since userdata partitions are for some reason 9gb with this one instead of 3. If you Downgrade to A11 using SPFLASH tool and this guide and after that install any version included here using recovery, it will work. Unfortunately, these files you sent in the link are ozip files and update packages while ofp files are firmware packages and they include everything. There are only 2 ofps -decrypted and not decrypted- available for now starting with A(EU), A08 (first ever firmware for EU) and A11(first update to EU version).

Hello again. Yes, I noticed there was an ozip file and deleted it.

First of all, thank you daeSundae for posting this info here!
Have you actually tried to flash the decrypted A.11 version? I did according to your guide. Everything went fine including the green checkmark after successful flash.
Then I held the phone's power button until it vibrated once, like a normal boot up. However the phone remained black and seems nearly completely dead now. It doesn't react to any key combinations (including Vol+-) and Windows reports a malfunctioning unrecognizable device.
Linux shows a device that identifies as "18d1:d001 Google Inc. Nexus 4 (fastboot)".
Fastboot does not recognize the device, adb however does, showing the correct S/N and state unauthorized, thus it doesn't accept any commands.
So the USB controller seems to be still alive, but nothing more.
To be clear: I don't blame you in any way, I'm just trying to provide information to step forward! So, what was your experience on A.11?

Hello! I'm sorry for the inconvenience I have tried flashing A11 file and it caused several problems just like in your case, however if you didn't select "Format All+ Download" mode you should be able to recover your phone. So, I had the exact same issue today and due to that I will be removing the A11 file from the links. Also, never forget to select Download Mode only! Several people bricked today and their IMEIs, Serial Numbers are all gone! Never select anything else than Download Mode!
So the solution is to download B53 decrypted files, load the scatter and untick listed partitions
opporeserve
,cdt-engineering,
mycustom,
special-preload,
userdata,
super
and then start the flashing in download mode. Now, you might be wondering "How am I going to go into the download mode again?" It's very simple. All you have to do is to keep pressing on Power and Vol- for some time and then, connecting to the pc with both volume buttons pressed while brom.bat is running. If you get an error, just reinstall device filters and that should fix the problem, then you can start downloading. After downloading these partitions to the phone, you will be able to see a boot animation and as well as a realme logo. Reboot to recovery, power of your device and then go into download mode again and flash userdata, dtbo and super partitions this time around. It should boot into system. However, the version will be B.53 but you can use the latest ozip (A.48), flash it from recovery and then format your data. It will bring you back to EU version.

So, i just read your reply again.
"Then I held the phone's power button until it vibrated once, like a normal boot up. However the phone remained black and seems nearly completely dead now. It doesn't react to any key combinations (including Vol+-) and Windows reports a malfunctioning unrecognizable device."
i dont think it's an issue caused by the device. Can you install oppo drivers from this link and let me know what happens afterwards? Or if you're fast enough you might prefer going into device manager by right clicking on Windows button and uninstall it's driver? I will also request you to start from step 2 to ensure installing drivers. I had the same black screen but my Windows was able to detect the Download Mode when i connected while both volume buttons pressed.

Well, good to hear, that your phone survived the faulty firmware. Although I select Download only of course I can't reach download mode any more. It is completely dead, Holding whatever combinations for even a minute doesn't have any effect. Normally you can force a reboot by holding Power and Vol+ for 10-15 seconds. If you keep holding it'll reboot, if you release both keys immediately after the screen went black it stays powered off. That's how I could escape the previous bootloop.
I've tried removing all devices and drivers and reinstalling them as per your guide, alas to no avail. My second, still intact phone (stock, unrooted), identifies in download mode as "USB serial device" on Windows and as "Mediatek Inc. MT6227 Phone" on Linux. The bricked always identifies as "Google Inc. Nexus 4 (fastboot)" throughout (buttons pressed or not).
It's a shame I didn't have the idea of unbricking with a B region firmware and flashing the A region later through recovery, because then I wouldn't have tried the untested A.11, but taken the verified route instead.

Well, as far as my knowledge goes BROM is burnt onto SoC and cannot fall into an inaccessible state. You should still be able to do access download mode even if that firmware was corrupt. Do you know if your phone has any charge or not? Can you try different volume and key combinations? A broken firmware shouldn't make the BROM Download mode inaccessible.

Oh wait. Is it identifying as fastboot? Then you should be able to (even if you don't have USB debugging authorization) use minimal ADB and fastboot tools to
use "fastboot reboot" command. Please keep pressing vol - button if you can while rebooting if it works. That should, if possible reboot you into recovery.
Also as you said, keeping pressing on power and vol+ buttons don't work in this state. In fact, in this state nothing visually works, there is no screen output and I'm actually pretty sure it's the same for begonia (RN8 PRO). You will need to ~ if it's detecting it as a fastboot device need to use minimal ADB and fastboot tools to get rid of that state. I didn't have the same issue as you though. While I was in same state, I kept on pressing on Vol - and Power buttons for around 30-40 seconds (obviously without a response from the device) and after that pressed both volume buttons and connected device to PC. Can you also try when your device powers off? Because clearly currently your device isn't powered off and cannot be powered off until the battery dies or you can somehow manage to escape from current situation.

I'm sorry for not letting you know Dinolek. I tried to create a guide but my Windows is Single Language and since it's not global version or something I cannot change its language. I had to find an English screenshot. If it's a problem, I'll just remove them.

No, I'm not Dinolek. I just talked to him and he accepted my instructions. Let the screenshots lie, I don't mind.

The phone was fully charged when it bricked, so yes, the battery will last several days I fear, esp. without driving the display.
Three buttons make 7 possible combinations. I've tried them all, pressing, holding and holding while connecting USB. No reaction at all, unfortunately.

This is kind of weird. The phone identifies as USB ID 18d1:d001 on Linux which is said fastboot device. fastboot does not see it, only adb does. But maybe it justs sees the device, lists it, but cannot communicate otherwise with it. I guess if the device was just silent (or dead) adb would assume unauthorized, in lack of any other behavior.
Window btw does not accept the device at all and lists an "Unknown USB Device (Invalid Configuration Descriptor)".

Sound also reasonable, however waiting for the battery to drain may last a very long time. I am out of ideas on how to force a power off otherwise (apart from sacrificing hardware integrity and disconnecting the battery of course)
Man, do I miss the old days when a ZergRush was all you needed to root and problems like this were solved by pulling the removable battery...

If it's detecting a fastboot device, the device isn't dead. What I'm guessing is that your device is working, and on fastboot mode but since there's no display output in this state it will only show a black screen. Can you do ADB devices command? Im guessing adb reboot requires authorization though, but it's worth trying. What I will be requesting from you is to try pressing (and keep pressing on) different key combinations while device is in that state for like a minute or so, for example keep pressing on Vol- and power for a minute then switch to Power and Vol+ for a minute and then keep pressing on both volume buttons and connect device. Can you also see the results after plugging your device into charge and letting it stay for around a minute? I know these might make no sense technically, but in my opinion randomness is your best friend to get rid of situations like this..

Hello. again. So, i have asked few people about your situation. Conclusion is, if none of these work you will need to wait until battery wears off and device turns itself off, i'm afraid. I will ask you to not use your phone for like a day and not to keep it connected to a computer for a long time. After making sure it powered off (which, i'm guessing there is actually no way to do that) make sure to prepare the brom.bat file plug in your device with VOL+ - combo and go on. Before doing this make sure to Device Manager > Action > Add Legacy Hardware > Next > Install the hardware that I manually select from a list (Advanced) > Show All Devices > Have Disk > Choose the cdc-acm.inf > Choose Mediatek USB Port and install it to not waste time. I hope your problems will be fixed. I have confirmed that BROM mode shouldn't fall into an inaccessible state because there's no efuse.ini blown. It must be there, but you're probably stuck in a mode that doesn't allow doing anything for some reason.

[OPN100][OOS TMO BE82CB] Unbrick tool to restore your device to OxygenOS

Disclaimer: By attempting any of the processes listed in this thread you accept full responsibility for your actions. I will not be held responsible if your device stops working, catches fire, or turns into a hipster and claims to have been modified before it was cool.
Hi everyone, similar to the previous threads for
OP3, OP3T, OP5, OP5T, OP6, OP6T, OP7, OP7PRO, regular OP7T, T-Mobile OP7T, regular OP7TPRO, T-Mobile OP7TPro 5G, regular OP8, T-Mobile OP8, Verizon OP8, Visible OP8, OP8Pro, OP Nord, regular OP8T, T-Mobile OP8T, regular OPN10 5G and regular OPN100 here is the EDL package (also known as MSM tools or unbrick tools) that can revive a bricked OnePlus Nord N100 bought from T-Mobile.
As this is a carrier specific MSM, it will only work with BE2012 model with build tag BE82CB
You should also be able to rollback your phone to a previous release of OOS with them if for some reason you want to go back to an older firmware
You can download the following versions:
ANDROID 10:
OOS 10.5.8
Mirror for first and last MSMs: https://onepluscommunityserver.com/
Instructions:
Launch MsmDownloadTool V4.0.exe.
On the login prompt select "Other" in the dropdown menu and click on Next.
Wait a few seconds until main window shows up.
Press Start button so that it waits for your device to be connected
Power off your device
Maintain volume up and down buttons to get into Qualcomm EDL mode.
Plug your device to your computer.
Should you not manage to do that and have adb access, you can use adb reboot edl instead
Wait ~300 seconds.
Enjoy your brand new device.
FAQ:
Does this work on Mac or on Linux?
Unfortunately no, tool is Windows only. You should need at least Windows 7.
Why is my antivirus freaking out when unzipping the archive or running the tool?
In an effort to protect reverse engineering from being done (and by extension prevent conversion process like it was done on 6T and 7Pro), OnePlus now use VM Protect V3 in their MSM tools. As this tries to detect debug environment, this is seen as malicious behaviour by some antivirus.
My device isn't detected
Go to device manager and make sure your phone shows up as QDLOADER 9008.
If it shows up as QHUSB_BULK, it means Qualcomm driver wasn't installed automatically by Windows Update. Download the latest one from Microsoft website at http://download.windowsupdate.com/c..._fba473728483260906ba044af3c063e309e6259d.cab (source https://www.catalog.update.microsof...updateid=8ee52ba0-bdef-4009-88cf-335a678dd67a ) and install it manually by right clicking on QHUSB_BULK and selecting "Update driver software" and "Browse my computer for driver software" to where you downloaded CAB file.
If you can't get into EDL mode by hardware keys, you may use adb reboot edl (will require your phone to still have ADB access)
MSM tool is stuck on "Param pre-processing"
Ensure you're using the Qualcomm drivers linked above.
MSM tool is stuck on "Sahara communication failed"
Unplug your phone, get in fastboot mode, turn off phone, wait 15 secondes and get back in Qualcomm EDL mode. You can also try using a USB 2.0 port instead of a 3.0 one.
What is SMT Download mode?
Just don't try to unlock that mode, it will wipe your IMEI and your Widevine certificate if you use it.
How can I fix "SMT config not found" error?

Please, help me with saving my device!

After trying to flash TWRP (by following this guide: https://www.thecustomdroid.com/root-oneplus-6t-guide/ ) my device would no longer boot to the OS,but (stock) recovery and fastboot modes worked, so I tried to fix it by flashing some Android 9 roms from https://forum.xda-developers.com/t/...t-stock-fastboot-roms-for-oneplus-6t.3862516/ , and flashing a stock Android 10 boot.img (for some reason).
But my attemps at fixing it by flashing only made things worse, my current situation is as follows:
Device: Oneplus 6T (6/128)
Version (either Global or T-Mobile): Unsure
OxygenOS Version: Unsure, only know that it is Android 9
Bootloader: Unlocked
- Neither Recovery mode nor TWRP work
- Bootloader and Baseband versions show as empty
- I can only access Fastboot mode and EDL mode
- A power outage left my main pc (which had the drivers, permissions and backup i had been using, and need, to do this) a burning mess
- I´m currently using an old desktop computer i had stored (which has Windows 7), but it fails to recognize my device.
- I have installed and tried multiple versions of the Qualcomm, Oneplus, Adb and Android drivers, but it never recognizes it
- Windows doesnt allow me to manually select the drivers for the Unknown device as ¨the specified folder doesnt contain a software driver compatible with this device¨
- By searching the system and internet it always says that ¨the best software driver for this device is already installed¨
- Both of the above were tried with a disabled driver signature requirement
- When using it on the other PC, the msm download tool, it always said that the image didnt match the device, no matter which of the 13 versions I tried
- On my current PC, the msm download tool doesnt detect my device
I implore anyone that can provide any help or advise to do so, as I´ve already spent an entire week scouring the Internet (including the Oneplus and XDA forums) for any solution, but so far, nothing has worked. Have a good day and thank you for reading my post.

Hey man.
I'm a dude with no OnePlus 6T but have a OnePlus Nord N10. But I do know the really bad punch-in-the-gut feeling of not having a device work at all.
What does "fastboot reboot bootloader" show?? (Does your phone reboot to the bootloader upon that command being ran?)
Also did you try to flash the stock Android 9 boot.img that your device was updated to?
As for the MSM download tool, the last replies I've seen show that some people trying that on Win11 recently have got it working.
Also check if these work? https://www.thecustomdroid.com/oneplus-6-6t-unbrick-guide/
How to Unbrick Your OnePlus 6T When All Else Fails
When flashing files through TWRP, ADB, or Fastboot, there's a slight chance for things to go wrong. Whether it's user error related or something else entirely, it's always good to have a backup plan. In most cases, you'll be dealing with a semi-brick or soft-brick, which can usually be solved by...

I really hope your phone gets fixed, man. Good luck!
