Then try one of the fastboot roms. I have had my best luck with Android 10 versions. Once you get any OOS, you can easily do a OTA update to the rom of your choice.
EDL is really hard to get into from Windows 10/11. The only way I can get it to work is on an old machine with Windows 7.

EDL mode works. Simply follow the procedure but press start before you connect your phone and dont connect any other android device. EDL mode does not work exactly as described in the thread here but it works well.

If you tried the Android 10 version then your only choice is to MSM it back to stock.
Try this
Turn your phone off.
Fire up the MSM Download Tool. Hit start in the Download tool so it will be sniffing for a phone.
Hold down volume up & volume down while plugging your phone into your computer. When the MSM progran connects and starts installing, let go of the buttons.
If it doesn't work, you just need to keep trying it. Make sure you hit vol+/- at the same time and hold for a few seconds, plug in the USB cable, then let off the vol keys. It's difficult to do and get right with two hands.
Sometimes it will also work if hard reset out of the boot process which means hit VU+VD+Power when it is booting up. Just make sure you have hit the Start button in the MSM toll so it will be searching for your phone and auto start when it catches your phone in the right mode.
You can also run adb reboot edl.

Looking around, the vast majority of problems people encounter while trying the MSM Tool is with the Qualcomm drivers.

Just out of curiosity, report back if that MSM tool worked for you. Never tried it myself because I've never bricked this phone, but curiosity.
No, I already tried that msm tool. It doesn't recognize my device. Probably because my device was on 9.0.10 or 9.0.6...im not really sure bc I tried restoring with a backup from 9.0.6 while I was on 9.0.10. But my computer did recognize it while it was in Qualcomm Download mode so maybe the toll just needs to be updated?
This happened to me when I upgraded from 9.0.7 to 9.0.10. When I booted into TWRP, all my internal storage was encrypted, so I couldn't flash the OS again from there. I tried to wipe just the data and dalvik/cache in a hope to fix it. Don't do this as my internal storage got wiped (most likely due to the encryption). I had to download and reflash the OS through OTG with a pendrive in the end. Possibly try to do that first if you have access to it instead of wiping the phone.

Msm doesn't need update. It's meant to work with phone off just pressing volume up I think, whatever version/type of ROM there is in it. Phone is recognized as a Qualcomm modem by the computer. Read carefully how to use it. It will restore a full out of factory 9.0.5 then you'll update it as usual.

Hi I flashed the installer by mistake once.
The solution is to flash the stock boot image in both slots.
Worked fine for me.

Umm.. That's probably what you did, but make sure to get the driver automatically via internet. If that doesn't help, perhaps a different pc/port/cable will do the trick (different pc worked for me).

Hard Bricked 6T (No TWRP, OEM locked, MSM not working)

Hello dear community,
I've been playing with my 6t for a long time, hundreds of custom roms, kernels, etc..
Lastly I went to official oxygen 10. I tried to install twrp via fastboot but every time I tried to push the files, I would get a error. I reinstalled drivers, tried different ports, different tools..
I got mad and blindly followed some article where someone suggested putting "persist" in the fastboot command, I tried it, I thought it is some kind of "force push" the file and that is how I probably corrupted persist partition. DUMB
Phone not booting of course and I went to restore it with Msmdownload tool.
It did not fixed it.
I tried different versions of msm, I tried going to Hydrogen, tried different USB ports, tried type C ports, different PCs...
No luck, phone is stuck at bootloop, with no TWRP and bootlocked.
I read somewhere that Msmdownload tool is not flashing persist partition and I assume that is the reason why my phone can't be restored.
Fastboot commands are not working anymore and EDL mode is probably the only possible way to communicate with the device.
I live in Montenegro and I can't send phone to oneplus to repair it.
I searched the threads and noticed that some users with similar problem eventually succeed to restore the phone by flashing it with Msm multiple times. I am still trying to do it but no luck.
I would really appreciate help from dev mastermind.
Thank you!
If your bootloader is locked again, i think it is not possible to use Msn tool. I think the only way is to send it for repair if you can't boot the phone.
But maybe i'm wrong and someone else know the sollution.

Thank you for response, but I think that msmdowload tool is made mainly to be able to flash even locked bootloaders, although I am not 100% sure...

You are correct. Msm tool will work on locked bootloader.
Man that sucks. Seems like you might be screwed. I screwed up a couple times getting to A10 but I was able to get msm tool to work for me. You are using it while your phone is powered off, correct?
Try different version of android with msm tool. Like try using the Android 10 msm tool then try the Android 9 msm tool

Hi GeekMcLeod, That's right, I boot it in bootloader mode, select "turn off" just to be sure that phone is shut down. And then I hold volume up and volume down together and plug the cable so it goes in EDL mode. Windows recognize it just as Qualcomm HS-USB QDLoader 9008, and that is all right I think.
Then I start MSMdownload tool and it flashes everything in around 200 seconds. I leave phone pluged in while it try to boots, but it never boot up. I left it for 45 minutes but still nothing...

Sounds like a driver problem to me. Try gathering a few (by Google, OnePlus, perhaps even Samsung) and keep trying different ones. I had to do this on my OnePlus One years ago. Then suddenly I found one that worked and I could revive it back from the dead. Not saying that it would work for you but it might. In my case it was a Qualcomm tool. If you still end up with nothing but dead ends today, I'd initiate a chat with OnePlus on this page (select your country at the bottom of the page first).

The only solution is to use smt mode inside msmdownloadtool, which will restore persist partition, but with some disadvantages.
Be aware that you WILL LOSE YOUR IMEIs and WIDEVINE L1, use it at your own risk.
If you decide to do it (remember you WILL LOSE YOUR IMEIs and WIDEVINE L1!) follow this:
1.- Run MSMDownloadTool.
2.- Click on Verify and wait till it says "MD5 Check OK!".
3.- Then click on SMT Mode.
4.- Then click on Start like you would normally do with upgrade mode.
5.- The you need to enter as password "te123" and select your phone's capacity.
6.- If it says something like "Port disabled by user", go to the top left corner and click on "SMT", "COM Setup" and check everything, then click on the left button, and retry steps 4-5.
7.- When the process finishes the phone won't reboot, so you'll need to hold VolumeUP+Power until it powers on, then wait around 5 minutes and your phone will be back to life!!
8.- If you have an IMEI backup, just follow this guide (https://forum.xda-developers.com/oneplus-6t/how-to/guide-oneplus-6t-unlock-bootloader-t3851789) (I don't know if this is the correct way to post links)
I hope you get your phone fixed.

Don't go to edl mode. Just have your phone powered off and use msm tool. I used it a couple times while getting to A10 and I only ever had to power my phone off.

@Papagaj do this....thats the only fix....I purposely wipe persist for to test something and I did that to recover from the boot loop.. persist store sensor information that vital to getting phone to boot....that's why it not booting..kernel is look for the sensor info but can't find it

It is highly likely that drivers are causing problem, I tried to flash it with msm tool on fresh windows where I let it to automatically download required drivers and the msm progress appear to be same as when I used drivers which are recommended by msmtool developer. I will try several more and will be back with results within few hours.

Is there a way to backup IMEI and WIDEVINE L1 at this moment? I think it is highly unlikely because functionality is limited to EDL only....
Or is there a way I can restore it later if I manage to fix a device with smt mode?

I recently got stuck in a weird bootloop thing with a, what i think was, corrupted boot.img. Try finding a stock android boot.img, boot to fastboot, and run the command fastboot flash boot <boot.img> on both partition A and B. If you can't find a stock boot.img, i managed to find one and can link to a download.
All right, here is the situation.
I finally managed to boot up the phone. amt911 gave working instructions on post #10. Thank you bro, you are awesome, and Thank you Tech_Savvy for confirming the method, you are badass who deletes partitions just for fun!
All right I got the phone booted up but as amt911 mentioned, I lost my IMEI numbers, without IMEI numbers you can't dial numbers, receive calls or use mobile data.
BACKUP IMEI NUMBERS FOLKS, you never know when the partitions will screw you over!
I was dumb one without backup and I had to contact Oneplus support for help. I was suprised how quickly I got into communications with one of the assistants.. in less than 10 seconds.
They ask you to do full reset via stock recovery and some other basic troubleshoots, after nothing, obviously, fix the missing IMEI they will arrange remote session to get your phone fixed.
You have to persist on remote session as some of assistants told me that I have to send the phone to repair.
Before they arrange session for you, you need to show them "proof of the purchase" ALSO KEEP THAT FOLKS I lost mine long time ago but luckily I found photo of invoice I took when I bought phone, phew*
I didnt have it at first when I contacted them and they say there is nothing they can do without a proof! DON'T STEAL PHONES FOLKS and then ask for support...
They will contact me for session within 48 hours and I will share the experience here.
Thank you again people!

Thank you JTVivian for helpful suggestion, but that method would not work. When your bootloader is locked, fastboot commands are useless, you can't flash anything.

Stuck in rescue mode after tried flashing stock firmware

Good evening! I hope you can help me.
I flashed LineageOS 14.1, but I wanted to go back to EMUI. I made all the wipes and tried to flash different stock firmwares through a forced update (volume buttons + power button), but it never worked. At that point, I read about a guy in this forum who suggested to create a flashable zip with Huawei Update Extractor: I followed the suggestion and tried to flash it with TWRP. No error was given, but when I tried to restart, TWRP told me I had no OS installed. I thought it was strange, so I tried to restart anyway. That's when I got in rescue mode. I can't get into the recovery and I can't use fastboot. What rescue mode shows me is:
RESCUE MODE
Attention!
Please update system again
Update User Guide:
*link*
*android avatar*
Error!
Func NO: 10 (boot image)
Error NO: 2 (load failed!)
Pressing the three buttons, I'm able to force an update. The problem is I can't find a firmware that doesn't get rejected. With Lollipop firmwares, it starts to install, but it fails at 12%. With Marshmallow ones, the installation process doesn't even start.
What can I do to make it work again? I'm very sad because this phone was gifted to me a couple of days ago and I already messed it up. I don't even know how to turn it off.
What can I do to get in fastboot mode? At that point, what should I do to flash the stock firmware? Or maybe do I need to find the first stock firmware ever installed into this phone to make the forced update work?
Please, I need help. Thank you in advance!
P.S. The phone's model is ALE-L21. I live in Italy, so I assume it's a European version.

Not yet, but I'm working on it. I found out that the device is recognized by my PC if I follow these steps:
1. Connect the phone to the PC and wait for it to go in rescue mode;
2. Wait until the notification LED stops to blink;
3. Disconnect the USB cable;
4. Press volume - and power button;
5. Reconnect the cable.
At that point, the screen turns black and the phone is recognized as "㄰㌲㔴㜶㤸". I installed the drivers and now it's recognized as "HUAWEI USB COM 1.0". I should be able to reflash the partitions and make my phone work again, but I'm still trying to understand how to do it correctly.
Any help is appreciated!

fastboot detects your device when you plug it into your computer?
I mean, if you run "fastboot devices" it shows your phone?
I've had this same problem but with an P8 Lite 2017, after flashing some ROM that supposedly was the stock one and trying to flash recovery I ended up with my phone bootlooping into rescue mode, I was able to "bypass" this thing rebooting my phone like crazy, seriously like after 20 reboot it finally booted into the damn ROM and I never touched the phone again. Sometimes when the phone ran out of battery and tried to power it on the phone booted into rescue mode and again after some reboots it booted to Android but now I want to install a custom ROM or at the very least root this damn phone so that's why I'm asking you if you have solved this, if you do then probably if I follow the same steps I would be able to fix that screen, hopefully.
If you are able to flash something start with flashing all recoveries your update.app has, maybe that's the problem (at least in my phone it is).

No, it doesn't show anything if I write that command...
I guess mine won't ever boot into the rom because it seems like there's no system installed. I made some researches and found out there are some softwares that let you reflash the partitions IF the phone is recognized as "HUAWEI USB COM 1.0". I'm still trying to figure out how to do it correctly though. I feel like if I do something wrong, then my phone won't probably turn on again.
In your case, you should be able to flash a custom rom without any issue. You just have to be very careful and inform you as much as you can: I don't want your phone to end up like mine?. Anyway, it seems pretty hard to go back to the stock rom, so think about it before you flash a custom rom. Also, make a Nandroid Backup is very important.

Phone acting strange - Bricked?

Hi
My phone stopped working a couple of days ago, I had been running a custom rom for 2 mths. I tried to restart and boot to recovery TWRP as I was going to reflash the rom. It charegs with no lights, for a day I couldnt boot to TWRP if it did it stayed on the start screen with no options. Today I can get options in TWRP so I tried to start fresh install but intstallation stops at step 1 ?
I have no idea what happened to the phone or why it just died, but dont understand why I can get into TWRP but cant flash rom etc. Also sometimes it say system destroyed message? but still can get into TWRP ?
Any ideas or help will much appreciated really would like to fix this rather than write the phone off.
Thanks

Hi, been playing with this when i have time over the last few weeks.
I have been trying to flash firmware, I dont seem to be able to get QFIL to work for me, it wont reconsise the port. However MIFlash does but I get errors, sometimes it flashes but doesnt end? other times i have had error flashing modem_a or error flashing modem_b (maybe device is locked).
In ADB it says already unlocked. Also I can only boot into fastboot, not recovery so i cant intall anything from adb sideload, it wont boot into bootloader just powers off if i try this. I guess theres no recovery on it now as I cannot boot into it.
Any ideas on where to go from here , EDL? I really didnt want to attempt to open the phone.
Thanks
Try miflash 2019 with stock rom pie latest with edl mode
if bootloader unlocked You can enter edl mode via fastboot with the command 'fastboot oem edl'

Thanks, tried this, says success then just carries on , so i have to disconnect. However when then trying to boot the device it shows Android one logo and if im lucky after a few attempts it goes to the screeen saying Hi There, where you choose your language to set up the phone. However it nows seem to be unresponsve and frozen on that screen.
Im beginning to think its could be hardware issue and phone is just faulty, i really dont want to bin it as its imacculate condition seems a real shame, but it is 3 years old i guess.
Any further help or ideas much appreciated.

try doing a factory reset from Recovery , good luck

Just another victim of the android 12 update, hoping for a revival

So im gonna start off by saying that im just some dumb 18 year old and have never actually posted to ask for help, only reading other peoples situations to try to figure out my own.
but introductions aside im just gonna jump in to everything wrong with my oneplus 8 pro (global)
I was on the OOS 12 beta for a while, ive been way too lazy to change it back since ive been occupied by other stuff.
I was using magisk and decided to do some fun shenanigans with it.
I get into bootloop after flying to close to the sun with modules - a common occurrence.
so I try to switch to a custom rom since I was gonna reset anyway.
I download CR droid's recovery and main rom, went into fastboot and flashed the recovery.
I notced that whenever my phone was plugged into the computer, the options would rapidly switch on fastboot's end
when I tried to boot to recovery after flashing, it would only return to fastboot
confused I thought that maybe the recovery was bad and try another rom, no dice
i submit defeat and go to msm tool to fix the issues
I get that "Sahara communication failed" error so I hold down the volume up + power for 13 seconds before trying again.
it flashed smoothly
after getting sad at all the bloatware that was on oxygen OS after a full reset, I get the motivation to try using a custom rom again, this time using a different rom.
same weird fastboot behavior
I was unable to go into recovery
I then tried downloading stock firmware to flash it manually
fixed nothing
I delete the boot and recovery partitions and flash them again, still no dice
I even make a partion called fart, before remembering that I do not know the partition structure of android so i Ctrl+C out before it makes the partition
I go back to msm tool again in shame
"Unknown Target Device"
I reinstalled drivers
switched computers and cables
changed the source of my drivers
nothing fixed this error
and every time I would try to do anything it would go directly back to fastboot.
I try reflashing partitions in this broken fastboot mode and it would only flash if I unplugged, selected reboot bootloader, and plugged it back in
I would then try to fastboot boot into TWRP or other recoveries i downloaded
they would shut off the phone
I remember a/b partitions exist so I switch over between them and try to flash stock OOS again
after more fiddling and nothing working, I noticed some more weird traits of fastboot
twrp did boot directly after switching my main slot, not specific which one just if the slot was changed.
the "this device has an unlooked bootloader" message did not appear
only on slot a would the oneplus logo show up on boot
again every option I would click would take me right back to fastboot.
I wait a day for the phone to die so I could use EDL that way, at this point the twrp method randomly stopped working so I couldn't go into edl that way.
"Unknown Target Device Param Preload"
and like I know Param Preload is a common error but nowhere could I find information on the unknown target device part.
the phone still vibrates if I hold the power and vol+
it just vibrates in a loop as if it keeps rebooting, probably fastboot just selecting the start key over and over when I hold it down.
vol- and power do nothing, and did nothing for the entirety of this story.
is there any chance of saving my poor instantnoodle professional?
## edit for people googling this
the problem I was having was that I didn't set the "target" button on the MSM tool correctly, so make sure its set to O2 or your appropriate reigon
1. Stop fastboot flashing with A12 or if you are on A12.
2. Read this: https://forum.xda-developers.com/t/...ro-8t-9r-with-oxygenos-12-coloros-12.4426167/
3. Rescue your phone using this: https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4084953/
4. Stay on OOS11 (Most custom roms INCLUDING A12 custom roms require OOS11 anyway.)
5. There is not much bloat on a OOS11 rom IMO but you can always use a debloater.

Maybe I should clear on what i have tried. since I have read both articles before I made this post (i scanned through them again once you sent them tho)
Ive tried...
The unbricking Msm qualcomm 9008 tool
ive used it a ton in the past
ive switched copmputers, cables, and the qualcomm driver, as well as reset the phone several times
also yeah im not touching oos12 after this with a 9 foot pole, but is there a way of knowing wether I can save it or if its too late and the motherboard has been fried.

Okay i guess this is another situation here. You are not bricked like the other peoplke as far as i can see because there devices are completly bricked. No connection to pc or vibrating at all.
Since you used MSM tool before it should work IMO. Does your pc regonize the phone? Did you tried to switch usb ports? Did you tried other versions of msm tool(eu, older verions, etc)?
Please make sure to follow all MSM instructions closely.

after a week of fiddling I DID figure out the issue
unsupported Target unknown was refering to the fact that I had the MSM tool set to Target mode, which I assume tries to set the region according to what the current device has. After selecting that to O2 for the global models, the flash worked fine. I ended up coming across some C stock of a google pixel 3a and will try messing with that so I dont have to go a while without calls or texts. Glad to know I learned some bit of responsibility from this excursion.
