[Help] oneplus 8 pro, OEM Locked, Bootloop - OnePlus 8 Pro Questions & Answers

Hello, I was going through stage to unlock bootloader, it was previously unlocked but a flashing error caused me to flash stock through MSMTool, I forgot to close/stop the tool after it was complete and upon one of the reboots it started the install again.. without realizing I attempted to boot the phone which caused the download to stop incomplete and booting to screen “upgrade download failed” I did select OEM unlocking in developer options as well as usb debugging although now it will not unlock bootloader; I can boot to bootloader not recovery and attempting to hold volume buttons while plugging into pc just pushing it to boot into the same fail screen. Is it possible to get my device into EDL mode so MSMTool can restart the install for stock? Thank you for any time given to help explain or direct.
Apologies if this is in the wrong thread

Try using the MSM tool already started and the hold down VU/VD/Power until MSM grabs it.

This just boots to bootloader, from power off, any other combination instantly boots to same error page

It doesn't really matter what it does if you have it hooked up to your computer and have MSM turned on with start button. It can find your phone in a between mode and start installing. It works for me every time, just hit all 3 buttons from wherever you are as long as MSM is in the start mode, it will find it and start installing.

If MSM does not recognize your phone there is something wrong with your PC.

Use another USB Port and/ or another USB cable.
Dont use Windows11
Install latest Universal ADB Driver
Install latest Qualcomm Drivers
Install latest OnePlus drivers.
In fact the last thing that will NOT work is MSM. If MSM does not work your phone is completly dead. (Which yours is obviously not because it boots into bootloader) This means if MSM does not work, there is something wrong on your end.
Talking about dead devices, be etremly careful what you do in Fastboot mode!

forum.xda-developers.com

Anything you do in the OS, like allowing OEM unlocking has **nothing** to do with MSM. In fact, a MSM flash will relock the bootloader. You will have to unlock again if you want to run anything except stock.
You have to boot the phone into EDL mode. Start MSM, then while holding the volume bar down, (UP and down, the entire button) plug into usb. Dont use the power button. (You may let volume keys go once done) There will be a dark screen, the only way to tell if in EDL mode is to check your device manager for the correct device. If you see anything on the screen you are not in EDL mode. I did use USB 2.0, do not use a hub.
I ask to start MSM first because on my Oneplus8, the EDL mode wont stay active for too long, unless MSM finds the phone.
If that does not work, put the phone into EDL mode and check your device manager (ports COM anf LPT) for QDLOADER 9008. Anything else, and the driver is not installed correctly and MSM won't work, If adb is working you can issue "adb reboot download" but the button press seems more applicable in your case.
There is a lot in the link below, it is for A10, I believe there is now a MSM for A11 but I have no experience with them.
https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4084953/

I have tried all these and msm will not recognize the device in any state so Iv reverted to using a repair shop msm was successful in making the device stock the problem came from rebooting the device while msm was still connected and running. Pressing any button would lead to the download failed screen where the device is not recognized or into bootloader where oem is locked and even though before boot I checked unlocking enabled the fastboot command would not unlock the bootloader, if the store fix it I will try get details on what they did

Softbricked axon 7, need help !

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

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

I need help! I wanted to relock the bootloader but then I coulnd't enter the recovery or fastboot anymore. When I press any combination it always turn on for 1 sec and then the screen turns off again but it still GOT recognized as QUSB Bulk. After I installed MiFlash the device is recognized as QDLOADER 9008. I didn't flash anything and I don't kno how to unbrick my device now .

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

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

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

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

Yeah, I screwed up, I know. But what is the point of flashing a full edl package for the phone if I have to put the phone in "what I believe id edl mode"?
And what shall I do if I succeed at something? Besided that, I can't find any EDL package for the A2017G?

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

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

Bricked Mi A1 - Qualcom HS-USB Diagnostics 900E

Hi guys
At first - I tried a method given on this forum: https://forum.xda-developers.com/mi-a1/help/phone-goes-to-qualcomm-hs-usb-qdloader-t3757867
This method doesn't work for me, because after disconnect my PC doesn't recognize my phone.
Phone is in Qualcom HS-USB Diagnostics 900E mode after OTA update (Mi A1 April Update) - strange
So guys... I know there are some magicians who can do almost everything.. Any ideas what to do?
Does MiFlash recognize your phone? If not, try instaling ADB drivers nd disable driver enforcment,
To kick device out of diagnostic mode and into QDLoader you will need either:
1) A "deep flash" cable
2) Take the phone apart and bridge test points
There are guides online for both, you can Google. You can make deep flash cable yourself fairly easily with a spare USB cable. Testpoint location is found easily via Google and can be bridged with tweezers or small flat-head screwdriver.
I did NOT have success with deep flash cable myself, I had to use testpoint method (and sadly broke my LCD in the process). The deep flash issue might of been because I was in Windows 10 x64 or on a USB3 port. If you do go that route and can't get it working, try with a Windows 7 x86 VM and USB2 passthrough mode before last resort of taking device apart.
Hold power button for 20 sec then volume down and fastboot will apear
1. install all necessary drivers (adb, qualcomm's HS-USB Diagnostics 900E, xiaomi flash tool)
2. use test point method as suggested by @CosmicDan - lots of tutorial on web on how to do this. Carefully read this before actually attempting it.
3. When you successfully do the test point method you will hear the device recognized sound on your computer
4. when you hear it, open miflashtool and your device should show up in it.
5. if not, reboot your PC. You should reboot your PC after installing all the drivers. See #1. (reboot required)
6. Once you successfully see your device on miflashtool, you can flash the fastboot rom of your choice.
7. (you might get stuck on "Can't receive hello packet" dialogue which will prevent your device from flashing), in that case change the USB port, possibly to USB 2.0 and try the test point flash method again to get detected and try flashing again.
8. Test point method should be done everytime you disconnect the USB from your phone and computer, hopefully you only need to do it twice.
9. Sadly for me, I am still unable to flash stock roms with this method, my problem is kind of unique, after flashing it shows me "Your phone is destroyed, press power to turn off" dialogue. lmao
10. if you get the same message then you dun goof'd. Hopefully yours will successfully flash.
Oh and only one version of fastboot ROM actually revives the phone, other fastboot roms actually puts it to coma (vibrating every one second, no display, no nothing). Only one fastboot ROM allows me to go to fastboot and flash recoveries. But if I flash any ROM (stock or custom) it kills the phone again and I have to repeat the given method and try again with another rom. I think the phone is effectively dead. What a **** phone! lol

Did you do factory flash mode? That's the only one that can recovery it, the other scripts won't flash everything.
Note that because you didn't backup partitions you will also wipe the IMEI, or so I've read (I backed up my whole device via emmcdl before brick so I was able to recover fine without miflash)

Actually I think I got scammed. It is Mi5x sold as MiA1. ****ing chinks! Anyway, I managed to install (Tiffany) on it and now it is booting to boot logo and bootlooping. I can get to fastboot and default (MIUI's) recovery by pressing button combos. But OEM is locked now so I cannot flash TWRP or other ROMs in it. I will have to EDL flash back to that MIA1 ROM to get it unlocked from fastboot. Otherwise MIUI unlocker asks me to link my miui account to this phone by going to settings, which I can't do because it is not booting up.
funny situation.

Issues with Recovery Mode, Bootlooping, Flashing, EDL, and ADB Commands

Not sure how to title this forum post, but this is the best I got. Forgive my ignorance and lack of knowledge on these topics.
I was trying to root my Axon 7 mini. After some searching to find out how to unlock the bootloader (like needing JDK, older Android SDK version to run android.bat, etc.), I finally got it to work. Ran Recovery to "apply update from SD Card" (can not remember the file right now) and was then ready to load TWRP Recovery. When I rebooted to the recovery TWRP image, it told me something failed and the phone had to be factory reset. I took my SD card out in fear of my data being deleted and "accidentally" clicked the power button. It then reloaded with a password prompt where I typed some random password (1234 because I never set a pin password nor knew what to do here), clicked submit, and then gave me some error; now my phone doesn't work.
The Problem:
- I can enter bootloader, sometimes, but can only run fastboot commands; adb device does not detect phone so can't run adb commands (always says the server is old or something and reloads daemon successfully but never finds my device regardless). Also, I don't think I can get it to run in EDL mode; MiFlash gives out errors too when trying to flash recovery images.
- Recovery mode doesn't appear or work; not sure if the MiFavor command prompts on the phone is recovery or not, but it's safe to say this no longer appears. This is also where I believe the phone bootloops. I can get the fastboot commands to flash a TWRP recovery, but it never actually enters the TWRP dashboard.
- Can not turn off the phone... I think. None of the command options that appear on-phone shut it off; however, when the screen does stay black, I'm not sure if it's in EDL mode or plainly off.
- Device Manager shows the phone as different stuff (namely Kedacom USB Device and Portable Devices/MTB USB Device). Sometimes Qualcomm appears, but it depends. More often than not, when my device does appear, there's either an error code (like Code 10, Code 43) and/or the device is grayed out.
Conclusion:
I just want to get my phone to work normally again, if possible. Currently, I locked the oem to see if fastboot commands could still work and now I'm stuck at the ZTE logo, so can't try to unlock it right now. What are the proper tools, drivers, programs, etc I need to get this phone back to normal? I've scoured the web and these forums for 2 days now with no luck and lots of either missing info or obscure info.
I bought this at Best Buy, so I'm assuming it's US Axon7 Mini version in terms of drivers (not sure if the box specifies any info that could be useful here).
Un-brick Axon 7 Mini
Dear all,
I experienced the same issue with my phone after I tried to flash it with custom ROMs and recovery.
I thought I lost it as I was not able to enter adb mode (not recognized on the PC) or even not able to enter EDL mode with the button combination so not able to do anything with it.
Only watch it boot and display the ZTE logo.
After some research, here is what I had to do to get it recovered.
First thing you need to get is an EDL cable.
I let you search on your favorite site. Mine was a Generic eDL Deep Flash Qualcomm 9008 Cable 2 in 1 for Z3 X/Octopus.
Until you receive it, make sure you have the latest Qualcomm drivers installed on your PC.
You can find it easily.
Then, connect your phone and your PC with the EDL cable.
Press the button on your EDL cable (there should be one) for a few seconds and keep it pressed.
Then, press the power button and keep it pressed for at least 20 seconds.
At this stage, you should have both buttons pressed and after some time, you should feel the phone rebooting.
After 20 seconds, release the power button.
Then, after 10 other seconds, release the EDL cable button.
At this stage, your phone screen should stay black and your phone should appear in the device manager as Qualcomm USBHUB (or somehting similar)
You are in EDL mode and should be able to perform a recovery flashing using tuliptool.
Then I followed the steps I found here:
https://forum.xda-developers.com/axon-7-mini/how-to/updating-uk-version-zte-axon-7-mini-to-t3717933
If you are still stuck, pm me.
Be patient, all will be fine,

I had a feeling an EDL cable was my only option left given everything I've looked up and the multiple methods I've tried. Wanted to avoid spending money on one but doesn't look like I have a choice given the circumstances - oh well. Regardless, thank you for the response and advice. Have to wait a while, though, to get the cable and test to see if this works.
If anyone else ever ends up in the same royally screwed situation as me, getting an EDL cable - or DIY one if you wanna be cheap and are confident enough to do so - is probably your saving grace.

[HELP] Bricked(?) OnePlus 6T after attempt to switch to International version

Hi.
I was following this tutorial: https://forum.xda-developers.com/oneplus-6t/how-to/guide-sim-bootloader-unlock-root-t3921795
It worked fine, and I booted into the international ROM. After that, I set up developer mode, and enabled OEM Unlocking as well as USB Debugging. I then ran the command `adb reboot fastboot` (note: fastboot, not bootloader) on accident. Now, the device has a black screen and is not responding to the power on button, nor any VolUP + Power combinations. When connecting the device to my PC, I here the windows device connected sound. For a while, the device showed up on the MSM tool, but when trying to flash it, it would hang on the first part, with status as Waiting for Device. Now, it doesnt show up in MSM tool.
Can anyone help?
Thanks
(Willing to go back to TMobile version)
Try to use this MSM Download tool...
https://forum.xda-developers.com/on...-mobile-oneplus-6t-msmdownloadtool-t3868916ce then after you get it back be sure to follow the instructions step by step on the conversion to international. I've done it twice without any issues.
Hope this helps

I bricked my Oneplus 6t from tmobile and would like to unbrick it if possible.

So I finally rooted my Oneplus 6t from t mobile. I bought the phone from swappa and it worked great. I installed a random rom and it bricked my phone.
I assume it is a soft brick since i can access adb mode but it requires me to power off the phone
and hold the volume keys along with the power button. Otherwise the phone will just boot up and
will be sutck in a continous boot loop. I then tried to fic this issue by using an msm tool found in
the xda fourms. I then entered recovery mode and perfomed a "wipe data/factory reset. I think it hurt more than it helped. Any suggestions on how to unbrick my phone?
I tried using alll three msm tools in this fourm.
when i use the msm tool (MSMDownloadTool 9.0v2) the update just stops after 4 secounds.
Also the update would fail if i were to use the msm tool (MSMDownloadTool 9.0v1 and MSMDownloadTool 9.0.13)
I have tried reinstalling the qualcom drivers but no luck.
I tried deleting the drivers and allowing windows to detect the phone nad download its own usb drivers
but it did not help.
i apologize if i post this in the wrong section. I am new here.
all links and info i followed to attemp to unbrick my phone can be found in this fourm

Okay so I open the msm tool. Then I have my oneplus 6t (t mobile) turned off. I hold both volume buttons and keep holding them while I connect the USB cable to the phone. Its basically in edl mode at this point. Then I press the start option on the msm tool. The bar fills up with green and completes itself. However a number appears that saids "4s" inside of the square. I assume that means 4 seconds left or completed in 4 seconds. My phone is still in edl mode at this time and will not boot up in any menu (normal.menu, boot menu/recovery mode). Unlesss I boot it manually.
And yes I tried a scenario where I held down both volume buttons, connected USB cord, and then let go. I also tried the scenario where I held both volume buttons, connected usb cord and kept holding the volume buttons until the process completed itself but I would get the same result. "4s"

Hi, Falzer. had all but given up and was prepared to head to T-Mobile to buy the 1+ 9 Pro (I almost wish I did not fix my phone... *BUT* I DID!
My issue occurred trying to flash a Magisk patched boot.img to my newly unlocked bootloader phone. I was following an article that alleged one could root the phone without TWRP. I will say this TWRP is your friend; don't dis "him". By the way, unlocking my phone wiped my data so always important to read the whole article first as it was mentioned in the NEXT step.
[Should be including the actual error here - it is found throughout these forums but I cannot recall the exact display. Basically, if you have an unlocked bootloader and then get to the CrashDump screen, follow from here:]
Retrieve the file, boot11.1.1.1.img and download from this thread/link:
OOS stable boot image and patched magisk boot image both for 11.1.1.1.
Leaving this here as i ended up boot looping from installing custom kernel, and it being a new release i was pulling my hair trying to figure this out. Flashed through fastboot with "fastboot flash boot_a XX.img, fastboot flash boot_b XX.img"...
forum.xda-developers.com
Do *NOT* mess with the other file to the right.
Hold all 3 buttons (2 volume buttons + power) and once/if you see Fastboot Mode, release the buttons.
Have ADB installed (you should be able to find plenty of directions for doing this).
From either PowerShell (or *maybe* CMD Prompt started as Administrator as I had been using this "successfully" for most functions):
fastboot devices
fastboot flash boot boot11.1.1.1.img
fastboot reboot
I could not believe my phone ACTUALLY booted (even with the McLaren animation intact; I'm sure one of the gurus here knows why) after all the failed attempts fooling around with MSM Download Tool [4.0] which almost EVERYONE swears by fixes/restores any brick. I understand ON ONE is forcing anyone to use any specific resolution; I am just trying to provide another last ditch effort.
EDIT/Caveat: I did not even check to see how old that thread above is, I believe late September and I had actually taken updates [via TMobile??] until the last one with a week to 10 days *but* that was probably wiped with the boot unlock so I do not know which "update" I got but figured I didn't have much to lose as I already had a "bad" version of a boot.img flashed anyway. Anyone with any technical explanations, feel free to comment. Thanks!
