A friend of mine gave me this phone after unexpected self shutdown. The phone was in a boot loop. At this point where I am right now I think I tried everything I can. I have read various guides and tutorials how to bring this phone back to life and nothing works for me. I suppose that there is some damage on mainboard but till I losse this phone I want to be sure. So the situation looks like this. Since the bootloader in locked and there is no working OS I am not able to unlock the bootloader. (If I am wrong here tell me please because I can't find a solution "how to unlock bootloader without having working OS"). The only metode to flash this phone in this state is to use QFIL. Flashing through fastboot fails everytime - booloader locked -> no *.img flashing. So I have 4 various versions of stock ROM for this phone and after flashing via QFIL the phone doesn't boot. It end with 3 possible ways. 1'st way - clasic bootloop. 2'nd way - frozen on loading screen. 3'rd way - black screen with blue LED, USB diagnostics state, 9006 port opened, no chance to flash because of closed QD port 9008. After this I have to erase every single one of the partitions made through flashing. Then I am able again to flash with QFIL.
I have no idea where is the problem here or what am I doing wrong. I tested the internal memory with a partitioning program in search of bad sectors -> 100% OK. Filled the whole memory with zero's and then formated it. It didn't help. Are every of my stock ROMs broken or is this phone realy damaged? Dear XDA community help me please! I have no clue what can I still try.
Tried ZUI QPST image or CM one?

CM through QFIL already tried. Doesn't boot. I've got .zip ROM images but without TWRP no chance to use it. I have got also an image in .qsb file but no idea how to push it into the phone. Will it work through fastboot to put the file into the phone and than flash through diagnostic mode ?

I just recommend you downloading this https://drive.google.com/open?id=0B7zm16vLHfdBVi1lWlMwelBBdXc . It's ZUI 2.0.49 for qfil, hope it works for you.

Already tried your copy. To be honest tried it many times in every way I could. The phone is now sitting for over 3h frozen on loading screen. It is never going to boot or tell me that this is normal... Ereased the whole internal memory by delting every existing partition and then flashed it via QFIL. Also tried to format the whole memory in ext4. Same result. Like I said the phone is laying right now for over 3h on the same CYANOGEN screen with some graphical artifacts.

OMG This room booted normaly. Thank you some much my friend! You made my day. It is a step forward. However all connections aren't working. I can't find "OEM unlocking" under Developer Options. I want to unlock the Bootloader as soon as possible so I will be able to put TWRP recovery and then flash it with any available CustomROM

Many hours frozen on black screen with blue led. 9008 QD port blocked. 9006 USB Diagnostics port opened. No chance to flash until all partitions are erased and the port is reset. Otherwise I need to try getting to the 9008 port by puting the USB cable while holding the "Vol Up" button and then flash it agin with QFIL.

Right now thanks to Borja Viera I used the working OS to make a "sdfuse" folder on the internal memory, put the .qsb image file into the folder and flash the phone through diagnostic mode. I have got right now android 5.1.1 on it and it booted normaly However the connections still aren;t working. I managed to enable "OEM unlocking" then got to the fastboot mode with a bit of help from AIO tool (because turning the phone with pressed "Vol Up" and "Vol Down" buttons at the same time makes the menu but no "go to bootloader" shortcut over there). Unlocked the bootloader manualy with minimal ADB. Then I wasn't able to put TWRP as the recovery because of some weird error comming every time I tried the command. So I flashed the phone once again back to CM 12.1 soft only to get other "the better one - with many options" bootloader. Tried flashig TWRP once again and voila! TWRP working!! Bootloader unlocked! In a while I will be downloading some CustomROM and turn this phone back to life... I hope so
[UPDATE]
Tried 5 different ROMs:
Two Cyanogen:
1'st - black screen blue led usb diagnostics state with port 9006 opened
2'nd - frozen on loading screen
Three CustomROMs:
1'st Official Lineage
2'nd Unofficial Lineage
3'rd AICP-12.1
All three are not booting. Phone resets itself on loading screen -> boot loop. Do you have any sugestion right now? In TWRP everything wiped and ROM installed on clean phone. Gapps installed too from Open Gapps website. Eveything done right with the instructions.
Is this phone really damaged?

If you're still in warranty, the best bet will be to get it replaced. Because it seems like a serious issue in the hardware.

Asked my firend about it. The phone is like 1 month old. He was making some pictures and the phone suddenly died and got to boot loop. He bought it new on ebay. Shipped from China. He already made some research about the warranty before he gave it to me. He made some calls and emails to customer service here in Germany and they told him that he has to send the phone back to China. No warranty in Germany. It is not worth to send it back to China because of duty tax on the way to China. They send him this phone on some special shipping method to avoid this taxes and stay with profitable shipping price. But if you need to send it back they won;t help you at all. And the dispatch price is a no-go.
Since I have decent experience with electronics and flashing various smartphones he gave it to me with a though that I will be able to bring it back to life.
I already said when I started this topic that I suppose that this phone has some damage on the mainboard because of the weird behaviour. I just want to be sure about that and try everything I can before I tell him that he wasted his money by buying this phone.
I want to thank you for your support! If you have some ideas what could I still try I will gladly listen.

Hi Guys my MI A1 was bricked i just use the test point to fix and my pc recognized as Qualcomm 9008 so flashed latest 8.0 everything worked but wifi and bt was broken so i decided again to put in EDL and flash it with same firmware after that MI flash shows success but device doesn't turn it jsut keep blinking led and goes to EDL everytime i connect to PC...tried with Nougat and Oreo firmwares same...i checked logs and saysthat device is successfully flashed and rebooted...but nothing just black screen and blinking led..Can anyone Help me?I can't send to Service because i will need to wait 1 month also i opened the back cover so i lost the warranty.....:crying::crying:
Hi,
did you try to flash with qfil or only mi flash ?
I'm not sure but may you ask Cosmic Dan he was planing to do an unbrick guide and he mentioned files which you can use with qfil to unbrick your device. I don't know how far he is with it.
But if you did manage to unbrick so far and only BT and WiFi is your issue aren't there several fix guides for the persist partition ?
For my personal experience after I had to unbrick my old n6p I had the same issue after flashing. Phone stays black and led just blinking. Try to long pressing power, or other button combinations while plugg and unplugging USB to pc and I mean really long pressing the buttons. It sounds a bit weired but my n6p came back and booted as usual.
I'm sry, but I can't tell you the right combination because I tried so much that time, because it was my only phone.
Good luck !
Bro if You Have A Backup Of Your phone Then flash It.

Qfil doesn't work because we have A/B Partition Layout....i have backup of my partitions that's not issue....
How much battery had you left at flashing ? May its just drained and not able to boot. Sometimes it's the stupid and simple things. If you have partition backups you should be able to fix your WiFi and BT.

You can get it back. You have lost the Wifi and Bluetooth (Mac Address files). You can boot your phone if it is in edl mode. Just press the Power Button for more than 30-40 seconds. Your phone will boot. If possible, try to stick the back cover and show it to service center. They will change your phone's motherboard! They don't know about edl and everything! They only change internal parts! :good:

Try updating your drivers. Happened to me once, MiFlash didn't detect it, but driver MANUAL update helped.
If u r using Mac Then Try in windows with Fastboot Rom.
Phone sent to Service Center....hopefully they will repair with my warranty,So No releases/No Builds around 1 month
After lot of waiting (FROM 23 MAY) this is what i got from my service center
" AFTER SERVICE REVIEWS AND SOFTWARE INSTALATION DEVICE REMAINS WITH A LOADING / DAMAGED MEMORY CHIP"
"The phone is stuck in EDL Mode due to improper use and serious damage from all sides. The same after a service overview and software installation could not be turned on or raised (shows no signs). The service order states that if you want to service, you will be offered an offer to change the motherboard. Greeting"
After that they tell me this"
"Otherwise, changing the motherboard with a working hand would be around 182 USD. Greeting"
i don't have that money it's too much expensive for me so i'm without any phone....

Windows 10 Pro, QFIL latest (2.7 or so), I used the latest stock ROM (tissot_images_V9.5.11.0.ODHMIFA_8.0) provided by Xiaomi.
I can only recommend to extract a ROM to a path close to your volume root, for example D:\Temp\tissot_images_V9.5.11.0.ODHMIFA_8.0.
By using deeper paths you'll probably get errors. Flat build. :good:

I used the drivers provided by QFIL. Btw. flashing a flat build by QFIL recreates the partition layout, it really doesn't care about two system partitions.
Flashed EDL mode when I went back from treblizing earlier without going back to stock partition layout in first place.
Qualcomm Flash Image Loader handled it flawlessly to restore the standard gpt provided by rawprogram0.xml .

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.

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

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?

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.

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.

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....

Oh. The few times I used it I just powered off my phone and connected it to my computer. Started msm tool and it did its thing.

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.

Ah you're right, i wasn't sure if that was the case but i thought i'd throw out the suggestion anyways.
i shut down my device by tapping power off. then removed sim card and sd card after screen went black. but when i tried to power on, it doesnt respond.. i tried holding the power button for 10s, it gives me a black screen and vibrates and instantly closes again.. so i cant boot into recovery, i cant boot to fastboot, and its unreadable on pc, it doesnt charge, no bootlogo, nothing. just bricked..
.
i dont know why, but it just bricked by itself.. i've been using mokee 9 date of 1/1/2020 thats the last update i installed, with add on su and everything was working perfectly and even if i reboot multiple times..
bootloader was unlocked so xiaomi centers wont help me..
how is it possible to make it boot again? i mean like wtf even happened? i did nothing.. i didnt flash anything and system was READ ONLY before powering off.. all i did was remove sim and sd cards... even after flashing mokee updates yesterday, it booted normally and idk what's going on..
any help?
EDIT: the phone's hard disk IC was damaged. I went to a tech guy and he changed it but then the motherboard broke entirely after flashing the qcn file for imei. Device out of warranty of course because of the damn bootloader. Thank you xiaomi for the great phone that only lasted one month before dying completely.
attempt 2
in attempt 1 i tried force reboot as mentioned, didnt work
attempt 2 : i tried force reboot while plugged to pc, this showed up
attempt 3
i tried to flash a new firmware, but device unreadable. must be on fastboot mode for mi flasher to be able to read it. im starting to lose hope.. the device is new though it makes me sad
on some topic of a bricked phone online, someone mentioned that he should try EDL mode, by cmd command FASTBOOT OEM EDL
so i tried it many times until it said successful. but still didnt fix anything, because it didnt actually boot into EDL mode, had to open my device physically and use test points. so attempt 4 failed
does this mean fastboot works?
after attempt 4, it said successful so if fastboot works like that then i can flash stock boot.img or something.. right? which image should i start with

this is the forum of the bricked phone similar to mine, except that i didnt try any flash like him it just happened randomly
https://c.mi.com/thread-2334646-1-0.html
attempt 5
attempt 5 failed, i tried flashing whole firmware one by one, i started with vbmeta, then recovery but it failed. idk what to do
notice
i have noticed that it only flashes small img files, if its 100kb or more it will fail. maybe due to device restart because the only way to make it read in fastboot mode is to force restart multiple times until it flashes. what to do now?
attempt 6
so according to this video
https://www.youtube.com/watch?v=yJoIiLE_w3w
he installed a driver (name in attachment) then refreshed on mi flash so his device became readable on mi flasher
i tried that but it didnt work.
final attempt.. out of hope
found the possible solution. its called a deep flash cable, i will just go to any tech guy and ask him for help.
see attachment for info.

In order to enter test point / EDL / 9008 mode, you have to physically open your device and connect two points on the phone's board. Search on YouTube for Redmi 7a EDL. If you get to EDL mode, you can flash original stock firmware via MiFlash.

Yes, I hate tearing up my device so I took it to a professional. He failed to open ADL but he did the 9008. Now he waits some kind of credit. Not sure if for the app to work or for the bootloader to unlock, although it was already unlocked but maybe somehow got locked..
Any way, expected reason for brick is either latest magisk module, or kernel tweaks..
I gave the device to a professional, but he also failed to flash it even with test point. He said he was searching for a file.. I dont remember its name, something like IMOH..
Now I need to know any possible reason that might brick my phone again to avoid it

The app he used was called ultimate multi tools
test point attempt failed
i did the test point, booted to 9008 mode but still nothing.
i think i know why the phone got bricked by itself, it got ARB stands for AUTOROLLBACK
read more about it here https://mi-globe.com/unbrick-your-xiaomi-phone-without-authorized-mi-account/
bootloader got automatically locked again.
Never lock the bootloader if:
- your phone was delivered Chinese version and you flashed Global firmware
- your phone was delivered Global version and you flashed Chinese firmware
- you changed system, vendor, boot or recovery partition
- you installed a custom or modified stock rom
ARB isn't an issue with this phone I suppose. Because I was on 11.0.5 and rolled back to 10.2.5 without problems.
Have you tried MiFlash Pro?

It seems that error is related to your computer. Reinstall drivers and MiFlash.

but im sure i have all drivers installed in fact i used mi flash more than once and it worked perfectly fine, and i swear i didnt try to lock it or anything, what happened is, mokee auto updates installed add on magisk and it was the latest version so i think this might have bricked it. idk..
ok i downloed all the drivers and reinstalled them, same error : "library not registered"
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.
