[GUIDE]ROOT/TWRP/MULTIROM/Cm13/RR on Locked Bootloader + Hardbrick Recovery

DO NOT FLASH HYDROGEN ROMS ON HELIUM, OR YOU GONNA HAVE A HARDBRICK.
IN CASE YOU HAVE ONE, HERE IS THE SOLUTION.
This was tested with Xiaomi Mi Max 128GB helium and localized rom from xiaomi eu.
I am not responsible for bricked devices or anything else. So at your own risk:
1. Install official MiPhone drivers
2. Download and install MiFash beta.
3. Download and unpack TWRP for miflash: 32gb or 64-128gb thanks @Abdess76.
4. Download ROM for your device, I recommend to try this one. You can install RR/CM Rom as well.
5. Run MiFlash with admin rights.
6. Turn off the phone, plug the cable to PC and halfway to the phone.
7. At the same time press Volume + and Volume - and plug in the cable.
8. Refresh MiFlash phone should show up. (If it didn't then make sure you did it right and u got drivers)
9. Navigate to your unpacked TWRP and flash it.
10. Now, boot ur phone with volume up. It's a bit slow. If it's stuck on miui logo, just release button and wait.
From here start to pay more attention:
11. TWRP can ask for password, press cancel and allow modifications by moving slider.
If you just need ROOT and your current rom, skip to the step 16. Also there is a recovery from boot in system folder. If you won't remove it, recovery may be replaced with stock one after reboot. Keep it that way if you want OTAs.
12. Format data.
13. Enable MTP and put modified zip in your phone.
14. Go to mounts and unmount system **
15. Flash your rom.
16. Flash latest supersu.
17. Reboot the phone.
In case u got NO OS message, then it means that u probably ignored step 15.
Also first boot may take like 15-20 minutes, since eu rom is deodexed.
Just to be sure, after installation mount system partition and navigate to the /system folder using TWRP's file manager and make sure it's not empty.
* In my case system didn't install because script could mount system partition since it was already mounted.
P.S. In order to update, you need to install OTA for offical rom via TWRP. Then without rebooting flash SuperSU, and finally using TWRP's file manager navigate to system folder and delete file named recovery from boot. Doing so will keep root and recovery.

Thank you so much for the guide! I will try it tonite
Waiting for boot loader is just too long..

WOW!!!! Just, wow..... I can not believe it but it worked like a charm. It took me forever to figure out my issue with the drivers, but after solving that I followed you step-by-step. And, lo and behold, it WORKED! Note for other users, Twrp took about a minute or two to finally boot up and it took me personally about 15-20 minutes before MIUI 8 finally booted. Just wait it out and you should have the amazing results that Doom Slayer has so graciously provided you
THANK YOU!!!!

I just done following your guide and it works!!
For rooting, I tried 2 times before it works. I believe you missed out a step to mount back system before flashing supersu.
So in the future, how do we dirty flash? Start from step 13?
How about clean flash? Start from step 12?
Thank you once again for this great guide!!
You saved me a lot of time waiting for Bootloader approval.

Yeah, dirty flash is you keep your data and format system and caches .
Clean flash is u format data as well.
The thing is that u have root, and ur phone is also secured. It's linked to ur Mi account, while it's locked. It's better to keep that way

Theoretically If you will ignore steps from 12 to 16. (Maybe u can ignore data formatting too)
Then you can get a ROOT and TWRP on your current rom.
And also theoretically while on miui 8 rom ,u can try to unlock bootloader without waiting.
Try this manual.

I have followed these steps and bricked my phone, spent the last 24h trying to recover it no luck.
I got an error while in the process of flashing the rom at step 16, then tried again and phone went black, stopped responding.
It's not detected using adb or fast boot, it appears in device manager as "Qualcomm HS-USB QDLoader 9008" or "Qualcomm HS-USB Diagnostics 900E", I have tried to flash again TWRP or the official ROM, it says success every time but the phone is still dead.
Could it be due to locked boot loader ?

Which rom did u flash, give the link please.
Are u sure it's for your version? It can be a broken file as well.
Does the device connects when u hold both volume buttons?
It's called emergency download mode, u can istall rom with miflasher.
There is a testpoint method also.
All u need is a pic from this post on http://4pda.ru/forum/index.php?showtopic=749580&st=700#entry51154086
U need to disconect battery, connect testpoint to battery and flash ur device with miflash.
After that let it charge, since this in your state phone consumes battery.

thanks for you answer, I flashed the MiMAXPRO EU ROM xiaomi.eu_multi_MIMAXPro_6.8.4_v8-6.0.zip (sorry as a new user not allowed to post a link yet)
When I hold both volume buttons the screen is still black but MI Flasher works with COM10, after flashing a ROM or TWRP again MIFlash says "success" but the phone is still dead and won't start up even after holding power button for a long time.
I'm happy to open the phone and try the method on the russian forum, I will try tomorrow hope it will start up

Don't worry about your phone, the testpoint method will work for sure.
But in order to prevent this kind of situations ,we need to determine the reason how did it happen and you need to help me with that one by answering following questions:
1) You have mentioned that you had an error 1st time.
I also had error which was cache related, and it's OK because that partition was just formatted. You tried to flash again... but did you unmount your system partition for second time?
2) What's the capacity of your internal storage?
3) Did you use internal or external storage? If external then I need the model and the file system that have been used on that storage.

Hello,
I managed to recover the phone, I installed a fresh windows 7 on another PC with only MI Flash Beta installed, device appeared as "Qualcomm HS-USB QDLoader 9008" as usual and I flashed the china ROM. Not sure why it wouldn't start previously after flashing, maybe issue with drivers.
1) unfortunately I don;t remember the syntax of the error, it was after a few seconds of flashing but the process seemed interrupted, I even googled it but my browser history has been purged.
2) 64GB (Helium)
3)I used internal storage, copied the zip on the phone using MTP.
Might try to go through the process again this weekend.

Well, I guess system was mounted and it gived u the error,but formatted it.

hi to all of you. I am very interested by this thread. Here is the story. I received my brand new mi max helium this week but it was the chinese rom. I am in France and my country did not appear in the settings. So I wanted to flash a global rom. I plugged it to my pc in recovery mode and a window appeared said that there is an update. I clicked ok and after a while I got stuck in the mi logo bootloop.
Then from then I tried everything possible from several solutions here, but nothing worked. What I got is the mi logo without bootloop, but nothing more.
I get the message that the bootloader is locked, but I can't get it unlock if it is in this state.
What I can reach is the recovery mode and the fastboot mode. But nothing else worked, flash or anything.
That is why I am interested to flash a recovery, in order to flash a clean rom, etc..
I did what you, Doom Slayer, explains, but I could not get a twrp flash. It ends with "receiving hello packet" in mi flash, and every thing stopped.
If I cannnot install any recovery, I cannot flash a rom.
So please if you have any suggestion, it would be helpful. Thanks a lot.

Did you disable drivers signature?
Also some people have a better luck on windows 7, u can try a virtual machine.
If you can enter EDL mode, then you should be fine.
Unless Chinese already disabled it in a new update.
I would blame drivers. Make sure u got them correctly.

Updated tutorial.
Uploaded TWRP for helium, so you don't need to edit updater script anymore, since script will get correct model.
Now you can try to get root on your current rom and unlock bootloader without Xiaomi's confirmation.
People having helium with unlocked bootloader may also have problems installing roms from xiaomi eu, if they have TWRP from hydrogen.
You may update using my recovery.img from archive using fastboot, or TWRP(will also work for locked bootloader).

hi Doom. Thank you for reply. But what do you mean by " disable drivers signature". I did not do anything but install the drivers and when I am on what I think is EDL mode(screen isi black) the driver is recognized as Qualcomm HS-USB QDLoader 9008(COM20).
Anyway, I will give another try and let you know. Thank you again.

I followed your guide and I could get the twrp installed. So I tried to install rom(following your link). It said rebooting in 5 seconds, and then nothing. The screen is black, no power anymore, no logo, no vibes, and no life at all.
I cannot get any more reaction from it. I plugged it to my pc, but nothing is connected. I was so happy with twrp working... Any idea?...

one more information I don't know if it can help, when I flashed first, I tried the "xiaomi.eu_multi_MIMAXPro_6.8.4_v8-6.0" and a message said "failed. This rom is for helium and this is hydrogen phone". Which is strange because mine is helium(4GB/128GB).
Then I tried with the "xiaomi.eu_multi_MIMAX_V7.5.6.0.MBCCNDE_v7-6.0" rom, and everything got ok, last message "success. The phone will reboot in 5 seconds", and from then, dead all over...

Looks like you installed hydrogen TWRP and that caused all your problems.

I've been very careful to install the helium twrp from this thread...

Soft Brick, A2017G, Bootloader unlocked, Stock Recovery

(or is it hard brick)
Hi,
A2017G
Started with marshmallow,
Unlocked bootloader
attempted to install Slim7
seemed to work but with some possible errors, (wouldn't sync with google... retrospect I should have looked elsewhere before...)
attempted in install stock rom
using
ZTE_A2017GV1.2.0B04_BootStack_by_tron1.zip
ZTE_A2017GV1.2.0B04_Stock_System_by_tron1.zip
which wouldn't boot
So I tried reinstall Slim7
then stock again,
then, like the noob that I am, I removed twrp with
ZTE_A2017GV1.2.0B04_Full_Stock_Reverter_by_tron1.zip
which installs stock recovery
so, now I have a stock rom that won't boot,
an unlocked bootloader
and stock recovery
Not sure what to do from here
thanks in advance for any assistance.

I can abd sideload and update from SD card, but everything I have fails signature verification.
edit: so frustrating trying to find that 1 zip

Just use MiFlash, that one's guaranteed to work. Read my DFU unbrick guide to know how to use it. Just skip the part where you have to disassemble the phone, since you can get to EDL mode by (with the phone off and the USB cable connected to the PC) holding both volume buttons and inserting the USB-C cable to the phone.

I did read your guide, was, hoping to avoid dismantling it...
I tried pressing all 3 buttons.
Am I understanding the procedure correctly:
[phone switched off] + usb-C cable connected to PC only
MiFlash running at this point??
Hold both volume keys in and in insert Cable to Phone
at this point is the phone supposed to switch on?
At no point am I supposed to press the power button?
fyi: I will try different combinations, is great to have a solution, thank you.
Ah.... ok... so, the phone will display nothing, rely on the sound of PC and/or the device manager check and/or hit refresh on miflash
Fyi to anyone, if you have axon7toolkit installed and thus can't install a second version of MiFlash, open up the toolkit and hit 7 (unlock bootloader) to fire up MiFlash... or just go to C:\XiaoMi\XiaoMiFlash
the FULL_EDL file I have produces a couldn't find script Error when loading into MiFlash
so far when attempting to flash all zips
I have started MiFlash with admin
unzipped FULL_EDL file to a folder in root C:\ and ensured there are no spaces in address.
Every time / Every file produces couldn't find script error when loaded into MiFlash
when I attempt to flash the file it says cannot receive hello packet and then times out with an error
Tried disabling anti-virus/firewall, still same error
upgraded MiFlash to 2017.4.24.0 ( older 2016 is included with axon7toolkit), this removes the couldn't find script error, but still not receiving a hello packet, gunna fiddle with the phone as I'm pretty sure the error is coming from there
YES!
rebooted phone, turned off, restarted into EDL, flashed the stock rom from zte site... is in chinese... but it works. Thank you Thank you
so adventure over, after all that I am back to 6.0.1...

I got it from here: http://www.ztedevice.com/support
selected:- United Kingdom > Mobile Phone > Axon 7
it offers a file "AXON 7(ZTE A2017G) SD card software package(328540B2634ZTE A2017GV1.0.0B11)"
which hints at being compatible with A2017G... but is A2017V and is chinese, although you can change the language in settings there is still plenty here and there, plus chinese bloatware
and No, I didn't get cell signal.
I've gone back to Marshmellow, I will try again, didn't think it would be so different/difficult... Although wow at MiFlash.

FFS!!!! Relocked bootloader and bricked it!!! there should be a warning!
you gotta laugh,
I am a bit livid, I know the guides come with disclaimers, however, you'd think it would be an obvious important warning to make... DO NOT RELOCK YOUR PHONE.
FFS!

... after I finally got it working again (thanks for the assist), I thought relocking it was just making it secure again. I been rooting/unrooting and swapping out roms since the galaxy s2, who'd think you can't unlock and relock... I do think there should be warnings as it is too easy a mistake to make... lmao stop doing dumb stuff you start first
My phone is insured so I'm not overly fussed, but others will be less fortunate.

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).
Wrapped with delicious Fajita [emoji896]

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.

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...

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.

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.

@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

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.]

Timmmmaaahh I am so glad to see you on my thread! I learned fundamentals of flashing on your guides back in Bacon days, and never bricked it even once! But this A/B partitions really gave me headaches....
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?

How do you mean? I can't get phone connected with msm tool if it is not in EDL mode.. It is not recognized when in stock recovery, bootloader or trying to boot up OS, that is only three states this phone can be at the moment.

You and me both! ? lol...

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.

Did you managed to fix this?

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.

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.
