Hello,
I have probably bricked my Huawei Vision by rewriting boot image.
However, I can connect* it to PC and it sees my phone as "Huawei Handset" (same with Windows and Linux). But Windows misses its drivers (non-bricked phone worked); Linux seems to work. No OS can connect to it using default (downloaded) ADB, nor Fastboot, nor SoftwareUpdateTool.
Its PCI ID is 12d1:c002.
How could I reflash it? I would prefer the ways without disassembling the phone.
Thanks
----How to boot the phone, so you can connect it to PC:
1. turn off my phone completely (vol up + power for 10 seconds - release power for a seconds and repeat it once again)
2. prepare USB cable, so you can connect it in few seconds
3. hold vol down + power and after ~1s, connect USB cable (still hold vol down)
4. when Huawei logo appears, release both buttons - your phone is connected now

The thread called 'Problem with huawei vision' still seems to be active. You may want to try asking your question over there.
Huawei (u8850) unbricked
I just wanted to relate my experiences in de-bricking this U8850 phone.
I installed 'Apps_2.6.35.7-perf+root+CWM_recovery 5.0.2.8' (firmware.nb0) using SUT to get CWM, and then installed Danile's 4.1.2
Good as far as it goes, but i could not for the life of me reproduce his kernel (my kernels are always unreliable), so after many days of playing, i decided to take the phone back to stock to see if i could reproduce the huawei stock kernel as a base to work on.
The problem was, how do you revert to stock; the phone was no longer recognised by SUT?
So I took a stock .nbo file and extracted the content (some java extractor found with google) in the hope that I could create a CWM flashable zip of the stock firmware.. a bit of research later, and i thought i had got the gist, put boot.img and system.img into a zip with a modified script file, and voila... a bricked phone.
At this point, i had CWM, but if the phone booted, it showed a flash of blue screen (I didn't know these ran windows ), and back to huawei logo. Also I think i had to dismantle to disconnect battery to run CWM, as it's not available just on the volume-up-power restart.
So then I did more research, and came across QPST, Qualcom's tools. It seemed this should know something about the files i had extracted. I could not correlate everything in the extracted fileset with what QPST seemed to expect, but the first challenge was to get QPST and the phone talking. using various drivers, QPST would sometimes see it, sometimes not, but nothing good seemed to be coming from it. I returned to trying to get SUT to work on my brick; again, with some drivers it would connect, but a flash always resulted in Error 4000 - DEVICE_NOT_CONFIGURED.
Then I read somewhere that someone had found a driver change made SUT work, so i investigated drivers more.
What I found was that if i ran up CWM, I got two Huawei devices in XP for which I could not find drivers.
The devices showed up as VID_12D1&PID_1022&MI_00 and VID_12D1&PID_1022&MI_01.
I took the Huawei USB drivers folder, and copied the qcser.inf then changed entries under [QcomSerialPort] to match my VID/PID values.
(the two that had matching MI_ values).
On driver update, I had a serial port, plus something I'd not seen before - a USB storage device which contained the phone's partitions!!!
This certainly seemed promising... so into SUT again, same error 4000...
So the I tried QPST; and yes, it could see the phone. Scared to do anything to brick it further, I thought, ok, try some memory diagnostics.
On running the 'Memory Debug' tool, as soon as I tried to get a list, QPST said 'this phones in diagnostic mode, it must be in download mode to do memory diagnostics', but even better 'Do you want to set it into download mode now?'!!!!!
Yeah! click the button, and I see a screen I've only seen once before (and i don't know why last time), black, with a line added every few seconds... which from all my reading I know is a good sign.
OK, then I closed all QPST apps, and ran SUT.
This time, the firmware flashed no problem. Was a bit worried as boot time is long (but it was effectively 'first ever' boot for the phone).
I hope this helps someone else with this or another Qualcom based phone.
Basic lesson is:
If you see Error 4000, it may be that the phone is in diagnostic mode rather than download mode.
If you don't have drivers, or don't have the right drivers, check you VID and PID, and try putting them into the .inf file
QPST may have a simple use after all... to force a phone into download mode when SUT fails.

it's actually not difficult to remove the battery...
but i read somewhere the 'volume-up + power for five seconds' will hard restart, but re-press power immediately will then turn it off (not tested myself; the back of mine is already off at the moment.)
Anyone here interested in developing a 3.x kernel? seems other phones with msm8255 have successfully got one...
u8850 power off

now i have tried it, and no success.
However, what i have found to work - if your non-boot is actually booting the kernel, but failing to initialise the phone, then you can still use adb with it... I ran adb shell, and then used 'poweroff' to power off my phone, which then meant i could boot into CWM recovery....
i HAVE THE SAME PROBLEME? PLEASE CAN U HELP ME TO SOLVE IT BY GIVING ME DETAILS.
it is working, thank you bro

HOLY GOD! F**K ME!!! I finally did it! THANKS A LOT, BRO! YOU'RE AWESOME!!!
Hi Guys!
The last day I wiped my ADB sideload cache and factory reset my device.
After that, my OPX keeps rebooting and I was only able to enter fastboot mode (but the device isn't listed when i type: fastboot devices).
I've tried following the guide for hard bricked OPX but couldn't do it because i'm running linux, so i installed W7 into a virtual box.
The tool didn't work becouse i cant seem to allow installation of unsigned drivers in a virtualbox and i am running out of ideas.
On top of all that, the battery is drained and now i can't even enter fastboot. It just says "the battery is too low, charge for a while before power on!" and I can't charge it because it keeps rebooting in an interval of 3-4 seconds.
I have CyanogenMod 13 installed and since i factory reset it, i assume that debugging is not enabled.
Up until now, i was always able to figure something out when i scerwed my device up, but this time i have no clue what to do.
Could anyone here help me?
All help appreciated!.
Will it charge if you leave it in fastboot mode? I'm not sure how virtual windows works but normally you can press F8 on startup and select allow unsigned drivers.
First of all, you should charge the device, otherwise worse things could happen.. Can't you just keep it in charge when switched off?
After you reach a reasonable level of battery, you should be able to fix it: if properly set up, fastboot works very well on Linux and Mac also, so you don't need VirtualBox etc.
Maybe check your installation with other phones.
If everything ok, you should then flash both bootloader and sys using fastboot: be sure to download proper images (this especially goes for OS), ie recovery ones.

The main problem right now it that i can't charge it. It turns on automatically when i so plug it in and then starts rebooting, so i can't even charge it to the point when i cant enter fastboot.
I'm still not sure about the state that is mentioned in the hard-brick guide, when i need to hold the volume up button for 10 seconds and then plug it in without letting go of the button. When i do that, it doesn't turn on, but also doesn't charge.
Whew.. Bad thing :-S
Honestly, this goes out of my knowledge: looks something related more to onyx itself than android internals..
If you can't find a special button procedure to stop the bootloader and start charge, I fear you'll need to have it serviced...
But before giving up I'd suggest you to wait for some more valuable opinions..

Thank you nonetheless!
I've managed to succesefully run through the unbrick guide and managed to repair it.
Okay I read sth on unbricking.
I found that win xp is the best option for driver compatibility (no surprises here, Win7+ are far more restrictive on unsigned ones: Ms politics) ..
So find an original Ms xp setup iso (a home would suffice, pro is better.. Still an optimal OS IMHO.. So sad it's been abandoned) and install it on VirtualBox.. It should be able to bind to your onyx via USB (warn: this is not automatic: you have to enable usb bind from VM lower icons - warn2: you can do it only with the device attached).
VirtualBox virtual HW is very well supported in xp with its guest additions (even direct3d works fine, for instance), so you shouldn't have problems with onyx drivers.
If you can start the phone in "unbrick mode" and link it to Xp, it should work I think ..
Otherwise prepare yourself to format your beloved Pc
Hi all, I will try to be as detailed as possible.
I have a MetroPCS LG MS323 which I bought as a second phone to use when I travel as my regular phone is CDMA and I wanted a GSM phone that I could use with a sim card. While on an overseas trip I paid a cellphone place to unlock the phone so I could use other carriers' sim card, it was working fine since then. However, as I don't use the phone on a regular basis it ended up sitting and the battery lost its charge. When I tried to charge it by usb, it started bootlooping (vibrate, LG logo, repeat). After that I pulled the battery and charged it using an external charger. The phone is not rooted. I tried the factory reset key combo, but it gets stuck on the screen which says factory reset processing........ endlessly. I tried to download kdz file and flash with LG flash tool but phone cannot get into download mode. When I press vol key and plug usb cable, it says LOADING.......... press volum up key until download mode starts But it gets stuck there and download mode never starts.
I downloaded adb and fastboot to a Windows 7 laptop, and LG drivers, but when I connect phone and open a terminal adb devices shows no phone connected.
I also downloaded Laf.img for this phone and Laf recovery tool for Windows but again I cannot seem to get computer to see the phone. If I try to use the tool it says "waiting for device"
One difficulty is to trying to plug phone to computer the right way.
Most of the threads say to have phone in battery charge mode with usb debugging enabled, but I can't select any settings if the phone is bricked.
If I just plug the phone to usb when it is turned off it shows a picture of battery but no sign of charging, and computer doesn't detect phone.
If I plug phone to usb first, then hold vol and power key the LG logo will go black and it vibrates, in that case sometimes the Windows laptop will see 2 folders, verinfo and image.
When I plug usb cable to Linux computer and phone is off, same thing just picture of battery but terminal only shows sda1 sda2 sda3 etc no sdb no sdc just like not detected.
If I hold vol down then plug usb it vibrates and stuck on LG logo.
I have also tried to plug usb, then press vol down and power until phone vibrates, then try to let go buttons before LG logo shows up. but it doesn't mount.
If I hold vol up and power, then plug usb. it vibrates and goes to LG logo.
Last night somehow I got it to mount on the linux computer but the file manager was going crazy opening multiple windows and a list of folders would show up for a second, disappear and reappear as if the system was trying to read the folders but having difficulty. Today I am not able to get it to mount.
I have downloaded a linux livecd with adb and fastboot, I haven't tried it yet because I am not sure the path to flash an img file from a different directory on the hard drive on the windows laptop.
I have downloaded aboot.img but don't know how I can flash it if I can't see the phone on any computers.
I have spent days searching for solutions but have not seen the exact same problem, other threads suggest things but often the symptoms are slightly different or with a different phone. So, first of all I need to know what kind of brick I have, because other solutions I have seen posted for completely black screen, or phone detected as qhsusb qualcomm etc. which seems like a different problem.
So the 2 main things are 1, to know which kind of brick because many of the solutions I see posted seem like a different problem.
second, what is the best way to plug to computer so I can see the phone?
I burned a live CD of FWUL and ran adb from linux, still says adb devices nothing shows up. usb cable is plugged in and phone is turned off. Am I doing this wrong? I held down power and vol down until phone vibrates and LG logo appears. adb devices - "list of devices attached" still has nothing showing.. I don't know why even in Linux I can't see any device attached. Also I tried with pressing vol up and power until phone vibrates.
ls /dev/sd* only shows sda sda1 sda2 etc
I have also looked at past threads about unlocking the L70 bootloader, but the bootloader.zip no longer links and the phone does not have busybox installed.
I tried to see it Windows Device Manager but it does not show up anywhere.
This probably won't help, but, when you're at this point, you'll try about anything.
Did you fully install the LG drivers on your PC? Obvious seeming question. I was doing an old Droid Bionic a couple months ago and didnt' switch the USB modes (charging, media, file transfer, whatever it had) to each mode before modding .
As a result, I bricked that Droid bad. It took me almost a week and a half to restore it. I'm not sure if LG drivers work the same way, though I've worked on plenty of them. I think I have an LG Leon still in the scrap heap as a result of trying to replace a cracked digitizer that was bonded to the LCD. If anyone needs parts for one, I've got em, cheap I think that's an MS345 if I recall.

Thanks, yes I had installed latest LG drivers LGMobileDriver WHQL Ver 4.2.0 before trying to flash .kdz file.
A tiny bit of progress to report, after getting a perfect timing to release the power and vol down keys I was finally able to connect to Windows machine. while waiting for drivers to install it was detected as QHSUSB_BULK in device manager, after drivers loaded now it is listed as LGE AndroidNet USB Serial {port (COM4). However when I run adb I still cannot see an attached device. I will look at solutions for the specific type of brick problem which has now been identified.

What I meant was after initially installing the drivers did you switch the USB mode on your LG to all possible settings? Some drivers (like Moto) install more functions only when first called. you'll know if you switch from say charging to MTP or RNDIS you'll see driver install reopen.
also when you first ran ADB and plugged in the phone you probably should have seen more drivers install.
Forgive me if I seem to insult your intelligence. I'm an IT pro w 30 yrs in tech and I didn't know about the multi driver USB functions.
Tom Sgt aka Rootjunky has a good video on this that i initially didn't watch figuring I'd been installing drivers forever. 5 more minutes of watching it would have saved near 40 hrs of work and research

thanks, I found his video for the G2 and no, I have never seen that with the drivers before! good to know. You can't insult my intelligence because most of this is over my head and I'm just trying to follow stuff I found with Google on XDA......
I downloaded and installed the Qualcomm drivers to try and identify if I have the 9006 or 9008 variety brick. However now when I plug in the phone Windows waits to install drivers, then says successful, when I look in device manager now I can't find the phone. But I did notice on the taskbar now there appears an icon named "intel graphics media accelerator driver for mobile" perhaps that is the driver Windows assigned to it? Device manager does have Intel Graphics Media Accelerator under display adapters. The other weird thing is that now it shows the battery as charging, which it never did the other times I plugged it into usb.

it has the firmware for your model links to drivers and the LG flash tool, (which is warned against newbies (what the hey, it can't get much worse, we were all newbies once, )
Can you boot into fastboot? if so, you could flash the firmware with that.

Hi, yes although those links no longer work I have found the drivers and flashtool elsewhere. If I try to run flashtool it cannot see the phone. I cannot get into fastboot, and download mode won't load. I cannot see the phone on any Linux machine. The most I can do it see the phone as E: Qualcomm MMC storage USB device in Device Manager, but no other details. Explorer can see 2 folders, image and verinfo. Is there anything I can do with these folders in Windows? adb and fastboot run from terminal still do not list any attached device. Windows did a search for drivers for QHSUSB_BULK, although in device manager it still says LGE AndroidNet USB Serial Port (COM5).
What I really want to do at this point is push aboot.img to the phone, but for some reason I can't access the phone with Linux or adb. maybe because it did not have usb debugging enabled before it bricked. So many of the threads I have seen require a working phone to implement the steps, is there any way to enable usb debugging when the phone doesn't work?

What I really want to do at this point is push aboot.img to the phone, but for some reason I can't access the phone with Linux or adb. maybe because it did not have usb debugging enabled before it bricked. So many of the threads I have seen require a working phone to implement the steps, is there any way to enable usb debugging when the phone doesn't work?

Of course, I had forgotten about that. In order to use fastboot, most flashing tools, you HAVE to have USB debugging on.
There are occasional ways around this, though they are few. I do seem to recall oding it on that LG Leon. OR it may have been a Moto e or G, let me look back at previous threads i've asked for help in.
(Hmm, perhaps taking notes, or just leaving a webcam running while I'm doing a new device might be valuable in the future, I think with remarkable hindsight.) :cyclops:

And no, you can't do anything to Android files in Windows, except see them. they are generally a different file system
One of the difficulties is just plugging it to a PC. 9 out of 10 times it is not recognized and nothing happens. So far the only way that seems to occasionally work is to plug the usb cable to the Windows 7 laptop, hold vol down and power, release both as soon as it vibrates. Most of the time I can't get it timed exactly right, but if I'm lucky sometimes Windows will detect the usb connection by following these steps. If I try on a Linux machine nothing happens, phone stays invisible. The most I've gotten with Linux is to charge the battery, but will not mount.
It is just a stock phone, not rooted, no busybox, no developer options enabled.
So this is a budget phone , spent hours obsessing over rooting it, did the whole process several different times several different ways,
the funny thing is , i can't event brick this device . this runs OREO 8.1 which a chopped down version of the full OREO 8.0 , basically it's designed for budget "entry level phones" . So i'm wondering
why they would make it so unbrickable? is it possible that this device doesn't even have a bootloader? if not why is it so hard to get to it?
Can't access fastboot mode nor the bootloader
One year later and this is still an issue. Here is my situation:
I bought an OTG (on-the-go) cord that allows me to connect a USB stick to my phone in order to extend my storage capabilities, but my phone doesn't natively support OTG (it basically doesn't have the drivers for it). In order to add support for it I need to root my phone, which I am having serious trouble with.
After hours of researching, installing, uninstalling, and factory resetting I've narrowed everything down to not being able to access the bootloader to select the fastboot mode. Here are my phone details:
Device Name: LG K20 (boot screen says "LG k20 Plus" however)
Model: LM-X120WM
Android Version: 9
Build Number: PKQ1.180904.001
Software Version: X120WM11c
As far as configurations go, I have:
- Enabled Developer Support
- Enabled OEM Unlocking
- Enabled USB Debugging
- Made my computer a Trusted Device on the phone
- There are no special "adb" options or configurations within my phone (I saw one website mentioned something about "adb" some options, but I only saw this once, and my phone doesn't have it anyway).
So far I have tried:
1) Holding the Power + Volume Down button for 10 seconds, then releasing the Power button when I see the LG logo, then repress the Power button until I see the "Factory Reset" menu. All this does it give me options to Factory Reset unfortunately (which I've done).
2) Holding Power + Volume Down button for 10 seconds. This simply reboots the phone and does nothing else.
3) I've downloaded, installed (on both my phone and my computer when needed), and tried rooting using the following programs: Dr.Fone, KingoRoot, RootGenius, iRoot, SuperSU Pro, and Superuser. There were some others I tried as well, but I determined I couldn't get anywhere with them specifically because I could not access fastboot mode (one example is "Magisk Manager").
4) Using ADB tools within command prompt (the most commonly recommended method) I tried rebooting the device into fastboot mode using the command "adb fastboot bootloader". The phone simply reboots and that's it, it has not switched into fastboot mode. You can confirm if you are by using the command "fastboot devices", which my device never shows.
5) I have gone to the LG website in order to download the drivers for this phone, however, while I am able to locate my specific device on the LG website, it directs me to download the "LG Mobile Support Tool", rather than download the drivers specifically for this device. I downloaded and installed the LG Mobile Support Tool but when the tool loads it does not recognize my device and tells me I need to install the drivers, which it gives me an option to do. Naturally I start the process to install the drivers but when it gives me the list of phone models mine is not in there *and you cannot proceed without selecting a model*. So, I tried using the closest model to mine (the LMX510WM), but it still didn't work.
6) Because LG does not have a direct download of the drivers for this device specifically I have tried downloading a variety of different drivers for this device. None have resolved the issue, but at this time *I believe* I have the most recent version of the LG drivers available "LGMobileDriver_WHQL_Ver_4.5.0".
7) I've tried adding the USB drivers through any install tools that came with them, and I've tried installing them manually via "Device Manager -> Add Legacy Hardware" and choosing the driver files specifically. This has not resolved the issue.
8) Installed the "wpdmtp.inf" file found within "c:\windows\INF" as recommended for Windows 10 users on one forum or another. Did not resolve the issue.
9) Installed the full Android Studio suite hoping something I was missing would be available, I also tried using the "adb" tools they provided: no love.
10) I also tried powering off the phone, holding the Volume Down button while plugging in the USB cord. This is supposed to do *something*, the instructions says I should enter "download mode", but on my phone does nothing.
11) the XDA-Developers forum suggested installed LGBridge_Setup.exe if I was having problems with drivers, which I have. When I ran the program it wasn't able to connect to my phone.
At this time I've uninstalled almost all software and all extra drivers from my computer (I left only the "LGMobileDriver_WHQL_Ver_4.5.0" drivers), as well as having factory reset the phone.
Everything is ready for another attempt, I've just run out of ideas. Thoughts?
Hi, I have also been trying to root this phone for the last year, but failed.
Everything is exactly the same as your phone regarding Build#, model # etc except i have software version X120WM10c .
The phone always wants to update but then it fails every single time.
I am hoping to root the phone so i can debloat it, and remove the restrictions preventing me from using it the way I want.
Anyone have any advice/info please post here. I will do the same.
Anyone? No response in almost a year.

first of all you guys, are talking about two diferent very disimilar phones.. mediatek v20,qualcomm on the k9.....
myself i have a x210wm k9 im trying to find compatable firmware for.
The phone is working fine without root. Seems very fast for $99 CAD phone!
I seem to have gotten my N200 in a state where it will not power on. No screen display, no vibrations, and unresponsive to volume and power buttons (standalone or combination). It's a DE2118, T-Mobile variant, network locked and not rooted.
Here are the conditions leading up to it:
The phone was plugged in to my PC via USB, (through a USB hub).
My Sim/SD tray was ejected.
I had been using an ADB shell to disable-user some apps and check out some various PM commands.
I did not terminate the ADB shell before powering down from the phone.
Once powered off, I held the volume up+volume down+power buttons to attempt to check out the recovery mode. I've never entered recovery mode before on this device.
The USB cable was still plugged in and I could hear the USB new device sounds on my PC a few times while I did this but didn't think anything of it.
Nothing ever appeared on the screen and pushing any of the buttons seem to provide no response.
Battery usage was at least 80%, if not closer to 90% before this happened.
It almost seems like the device is powered on and running as there feels like there's some very slight warmth on the back panel, near the center just under the camera area but I might just be imagining the warmth.
I'm aware that it needs to be network unlocked before it can be rooted as per other threads and I have not tried any root methods.
I still have my ADB shell dialog up but there really isn't much interesting in it besides a lot of the command help dialog.
What are my options?
Note: I recently installed the Jan 6th android 11 security update maybe a day before.
Edit: For anyone looking at this later, the phone came back after a complete battery drain and partial recharge and I was able to replicate the bricked state performing the same thing, usb debugging on, plugged in to usb hub on pc, shut down phone, then holding all 3 buttons down for a while.
Windows or Linux pc?
Does your device show up in device manager if windows?
If Linux, do you see the device if you run
adb devices or fastboot devices?

I'm using Windows 7 mainly.
It shows up in device manager when I plug in the USB but with error code 28, unknown driver.
In Win7, "adb devices" lists a blank line for devices.
In Linux, "adb devices" lists a blank line for devices.
In Linux, "fastboot devices" has no output at all.
If your phone is showed in device manager you should be able to give him his life back...had the same situation long time ago with my oppo find 7..
Try this, and see if it'll recognize you for MSM download.

Will give it a try. Going to be a few hours to DL the file as I'm on an extremely slow connection atm.
Well, I think that made it worse. Couldn't get the Qualcomm CAB drivers working on Windows 7, but got it through Windows Update. The MSM tool went through the process fully but afterward I unplugged the device and tried to boot, still no response, nothing on screen, no vibration. Now when I plug my device back in to the USB, I have an endless new usb device noise and windows says "Unknown Device". Device manager refreshes constantly while its plugged in. Looking back I should have probably tried ADB first before running the MSM tool.
After almost 24 hours of being unplugged, I tried plugging it in again and it finally had some signs of life with the low battery warning and then TMobile splash screen+vibration+sound after about 5 minutes. Still waiting on it to charge up for now. Probably just needed to be power cycled in the end instead of attempting to flash anything. I sure do miss the days of removable batteries.

In the future, you can power cycle the device by holding all three buttons on the phone for 30 seconds while it isn't plugged into a PC.

I had tried that yesterday to no avail. Was very strange. Everything seems to be working as normal now, though factory reset from running the MSM tool. I'm wondering if I'd be able to duplicate the issue again.
Could not replicate with USB debugging off and plugged directly in to my PC's USB port, but turning on USB debugging and plugging in to my USB hub, shutting down the phone, and then power cycling with all three buttons brought the same bricked state.
Don't know for sure if the USB port matters but while bricked plugging in to the USB hub always gives a USB device error sound. Going directly on PC it connects fine as a new device (as QUSB_BULK without drivers or Qualcomm HS USB QDLoader 9008 with drivers). ADB/Fastboot commands from PC's command line don't seem to do anything.
I did notice the fastboot menu show up on screen for a second when power cycling this time and I don't recall it appearing the first time. I think i may have had "advanced reboot" turned on the first time, while it was off this time.
Powercycling actually reset it this time.
Possible solution
It would seem that you can force MSM to write both a and b slots, which might fix your issue. Might be worth a shot
Note: If this swaps you to the Tmobile software, there's no guarantee you'll have anything but a phone that cannot be bootloader unlocked again. Since unlocked have no unlock token, trying to do so with a phone that isn't technically Tmobile may be an issue.
Just had the same problem. Holding all buttons for 30 seconds worked.
if you bricked it and you have tmobile variant you can restore it weather you have a locked or unlocked bootloader.
you have to get your phone in EDL mode, once in EDL mode you will see the "QUSB_BULK_CID" in device manager. you will then need to install qualcomm drivers (if done manually you will have to endable windows test mode, if you use the qualcomm USB driver installer then it will do it for you and you will be in test mode upon next windows reboot.) Reboot windows in TEST MODE. NOTE: i said WINDOWS TEST MODE... Once in windows test mode the driver should function and look normal in device manager. From there just open the MSM tool for your version of Nord N200 and flash and wait about 3-5 minutes. Reboot the phone and you are back in Oxygen OS.
Tips and extra Files needed below:
for the tmobile NORD N200 MSM tool
Index of /list/Unbrick_Tools/OnePlus_Nord_N200
The installer for the QUALCOM USB drivers can be found here at this website (ONLY use the QUALCOMM drivers from here, do not use any other file as it is for a different phone):
droidwin.com/unbrick-oneplus-7-pro/
once done unbricking and restoring your phone you can then exit windows test mode by running
bcdedit -set TESTSIGNING OFF
at the windows command prompt as ADMINISTRATOR.
