The TL;DR is, I bricked my phone (TMo Nord N200 5G, SIM unlocked, Bootloader unlocked). I'm trying to use the MSM to recover it. I can't boot to EDL (hold down volume up and volume down at the same time, while pressing power or plugging a USB cable into my PC). It just boots to Fastboot when I follow that procedure. I can't get to a place where I can use ADB commands (ADB shows device "unauthorized").
Longer version, my stock phone was upgraded to the June patch level, I think.
I did the SIM unlock, unlocked the bootloader, and installed the drivers.
I successfully flashed the latest PHH squeak FOSS by following this guide but it had some quirks that I wasn't completely satisfied with.
I flashed a SparkOS GSI linked from somewhere else, but it constantly beeped at me after I disabled Google Play Services, so I decided to move on.
I think the next OS I tried was CRdroid from the same place, but I also replaced the boot.img with a stock one that was patched for Magisk. I can't remember why I thought this was a good idea. There was also a thread that said Magisk doesn't like having nothing in system_a so flash this blank partition using these commands. It always errored out, but I tried it before rebooting.
At this point, my phone would either boot to Qualcomm CrashDump on its own, or Fastboot if I held volume down.
Using the latest Fastboot Enhance I was able to get into fastbootd by switching to "A" active, then rebooting to fastbootd. Have to remember to switch back to "B" active to get anything else to work.
I've tried flashing a few different things since I can get to fastbootd now. I'm no longer booting into the Qualcomm CrashDump, it reliably boots to fastboot as long as I'm "B" active. I just can't get anything resembling a working OS.
I've tried flashing the OTA TMo with Fastboot Enhance a few different times, and a few different GSIs through fastboot, and I really want to get back to stock now so I can start all over.
I've also tried a couple different MSM tool versions, but since my phone is never in EDL, it's never recognized.
Thank you for any assistance.
Holding the Vol +/- & power WILL force boot the N200 to EDL mode regardless of the software corruption as this is at the hardware level.
The thing you need to be concerned with is that you have the latest Qualcomm ADB tools installed so msmtool will recognise the phone while in this mode.
Install the latest adb driver and go into that folder when typing the command as you might have older adb installed already at another location (and in the system path) that is running instead.

Then you need to have msmtool running and ready to begin and the mouse button hovering over the start button. As soon as the first logo screen comes up, it will only go into EDL mode for about 3-4 seconds and then move on to booting and dump you into fastboot if the rom is corrupt/missing. You need to watch msmtool on the first line and the second it shows up, click start and it will flash.
If you are still missing it and in fastboot I think the the N200 supports the force phone to edl mode by fastboot command:
fastboot oem edl

Thank you for responding!
The command fastboot oem edl is returning either:
FAILED (remote: 'Command not supported in default implementation')
FAILED (remote: 'unknown command')
I'm running fastboot version 33.0.2-8557947, it's not in my system path.
From a full power off, holding the buttons and plugging in the USB cable, it's about 5 seconds until I see the OnePlus logo, then 2 more seconds before I drop into Fastboot. I'm not sure what I'm looking for, to confirm EDL mode. I'm not seeing my Device Manager update in that time, and the MSM tool isn't displaying anything, either.
try insert cable then volume + and - and power. keep it holding for 10-15 seconds or till you see qualcomm device in device manager
qualcomm drivers
Qualcomm_Drivers_Setup.exe
drive.google.com
try holding both volume buttons (make sure its off!) then plugging your phone in to the computer with msm tool open (you can pre-press the start button) (make sure you have all the drivers installed)
How can I verify that I have all of the required Qualcomm drivers installed?
I've run pretty much every driver install in this thread, or that I could find by searching, and it still seems like my laptop isn't recognizing the phone.

Open up Device Manager in windows. and then attempt to connect it to the computer while in EDL mode. In EDL mode it will still look like it's off btw, that confused me a lot.
You're looking for a device to show up in Device Manager when you connect it. If you're in EDL mode and have the driver's installed correctly it'll say qualcomm-something-something. If you see unknown device, you don't have the drivers installed. If no new device is detected either you're not in EDL mode or you should try a different cable.
Same issue as OP, won't boot into edl
edit: use USB 2.0
You can try enumusb.exe here: http://www.temblast.com/windows.htm
Code:
C:\>enumusb.exe /l /v05c6 /p9008
It will list the first time that a QUSB_BULK was plugged into a port, even if there was no driver found/loaded.
If you want, you can clear past connections by (needs to be admin command line):
This does no harm. I clear everything out occasionally, it just means that next boot will take 5 seconds longer while it discovers "new" devices and installs the same drivers.
Code:
C:\>enumusb.exe /d /v05c6 /p9008
Or, if you don't like that, just plug your device into a different port and see if another port is listed in enumusb.exe /l
On that same page you can find usblog.exe
You just run it and it will show you what pops up and down.
But, this only shows devices that Windows has loaded drivers for.

I didn't know there was a mode where it was powered on and the screen stayed off.
I finally got there by this path: Fastboot -> Recovery (I think?) -> List of languages, I chose English -> Power off -> Yes, really -> Hold down VOL+ and VOL- until I noticed the Qualcomm device in Device Manager
So I'm in EDL mode now! But my MSM tool crashes immediately on launch. So new problem, at least.

Try my native Windows EDL client. It uses the same Firehose loader as your stock tool does.
At the very least this will give you a second opinion.

Hi all,
What I did:
- Install TWRP
- Installed a bad ROM through recovery mode
- #brick
Now:
- Stuck in mi logo bootloop
- I can't get to EDL
- I can get to fastboot, but I can't seem to run any commands on my PC
- I can't get to recovery mode
EDL Mode
- I can't seem to get to EDL mode where the red light flashes
- I have tried going to fastboot --> Removing power --> Power + and Power - and Power. Wait for Mi logo to flash twice, and it goes into "Power off mode"
- When I connect to USB again, it connects to the PC and charges
- In device manager, I can see Xiaomi Composite MDB Interface
- No connectivity over adb command
Fastboot Mode
- I can get into Fastboot
- Connect Fastboot into the PC, I am unable to run any adb or fastboot commands.
- Fastboot devices shows nothing, adb devices shows nothing
- In device manager, I can see Android Bootloader Interface
I've tried many soft options and have read through probably 30+ guides. I have not tried the test point method because I do not want to void my warranty.
Anyone experience this and can help?
Thanks!
Try re-installing the driver and see if those adb/fastboot commands work.
U said u installed TWRP right . Then u can go to recovery by pressing volume up+power button and then install another custom rom or stock rom but if u have unofficial unlocked bootloader then flashing stock rom will relock ur bootloader and device will not bootup.So go for another custom rom like resurrection remix its super stable n smooth too.
Follow these two tutorials.

To enter EDL mode, you need to unplug the battery, wait 10 seconds, replug it. Then, remove the USB plug, replace it, then while holding both volume + and -, plug the phone in the computer using the original cable.
Make sure to check what you're getting in device manager. If you get USB_BULK, you need to download the drivers. If you're getting diagnostics, you did the earlier procedure wrong so try it again. If you're getting 9008, you've gained access to EDL.
WARNING, THIS GUIDE WILL WIPE ALL THE DATA IN YOUR DEVICE.
!!! Whatever you do, it is at your own risk !!!
This procedure will unbrick any Axon 7, returning it to stock. It fixes any kind of brick as long as your hardware is not damaged. You can't damage your hardware using software so if you have a healthy unit, you can recover it from any flashing "accident".
1. GET THE SOFTWARE
You need a Windows PC, Windows 10 is highly recommended. Do this:
01. Install MiFlash in your PC. It includes the Qualcomm Snapdragon SoC drivers, nonetheless you can always install the latest drivers.
02. Download the EDL flashable stock firmware package for your model:
A2017 (China): B14_MIFAVOR5 Android: 7.1.1
A2017G (Europe): B10_NOUGAT Android: 7.1.1
A2017U (Americas): B35_NOUGAT Android: 7.1.1
03. Unzip the firmware ZIP file to a folder in your hard drive.
2. ENTER EDL MODE
Option A: USING THE REBOOT COMMAND
If you still have access to your system but not to recovery or fastboot, then you just need to install any terminal app, open it and at the app's command prompt enter:
Code:
reboot edl
. You device will reboot into EDL mode. Now you can safely plug your Device to your computer. In your computer right click in the Windows Start Menu icon and select Device Manager. Under Ports (COM & LPT) your device should appear as Qualcomm HS-USB QDLoader 9008 using a virtual COM port. If you can see it, then you can continue to the flash section, step 14. Otherwise, if you do not see anything or a DFU device, then you'll need to explore the next option.
Option B: USING THE BUTTON COMBO
04. Press the VolUp and VolDn buttons in your device and keep them pressed.
05. Now press the power button until the red LED flashes, it does it really quick. Then release the buttons, starting by the power button.
06. Plug the device to your computer.
In your computer right click in the Windows Start Menu icon and select Device Manager. Under Ports (COM & LPT) your device should appear as Qualcomm HS-USB QDLoader 9008 using a virtual COM port. If you can see it, then you can continue to the flash section, step 14. Otherwise, if you do not see anything or a DFU device, then you need an EDL cable.
OPTION C: USING THE EDL CABLE
So, you need to get a Qualcomm EDL cable. With it you can recover from any situation. I use this one, DrakenFX uses this other model. There are cables out there not working properly so do not try to save 4 or 5 bucks and get yours from a reliable source. Alternatively you can solder your own by following this guide. If you are in an emergency (or your patience threshold is very low) and have a thin wire around you, then you can follow this DIY hack video.
Do you already have the EDL cable? then follow these steps:
07. Connect your bricked Axon 7 to your PC using the EDL cable.
08. Press the EDL cable button and keep it pressed.
09. Press the Power button of your bricked unit and keep it pressed too.
10. Wait 20 seconds.
11. Release the power button.
12. Wait 10 seconds.
13. Release the button of the EDL cable.
Voilà, your device is now in EDL mode. The device manager in your PC, under the ports category, should detect it as Qualcomm HS-USB QDLoader 9008. Now you can proceed to the flash section. If this procedure doesn't work, then your unit could have a hardware problem. Your only hope is to dissemble it by following this last resort guide.
3. FLASH FIRMWARE
14. Open MiFlash in your computer.
15. Click Browse button and select the folder you created in step 03 with the stock firmware files.
16. Click Refresh button and your device will appear listed as virtual COM port.
17. Click Flash button and wait for a few minutes until it finishes. Note that the bottom options are not applicable.
18. Now you have a stock Axon 7. Your data partition will still have garbage data, so you should enter recovery by pressing VolUp while rebooting your device with the power button. Release VolUp only when you reach Recovery. Using Recovery do a Factory Reset of your device.
That was the last step. Hopefully now you have a fully functional stock Axon 7.
By the way, this guide can also be used to return to stock any working device for selling or service!!!!
Cheers!!!!
Nice! I just disassembled mine and did it that way the other day.

I don't know what you mean about converting an A2017 into an A2017U. They are the same device except for the radio, that that's a hardware difference. You should always use the right modem firmware for your radio hardware so you should use the A2017 modem firmware. After unbricking your unit, you can unlock it again and flash any universal firmware the same way you did before. It is a long but safe process.
yes, i meant to say that i flashed U radio over my A2017
so China version is for me.

If you flashed the A2017U radio in a A2017 hardware and worked fine for you, then you can use the A2017U B35 stock firmware.

It should be locked. But in case you end up with an unlocked phone, then locking it is very easy. You only need to connect your phone, enter into fastboot mode, download the adb/fastboot tools and execute the command fastboot oem lock from your computer.

I can't get into EDL mode. I hold down volume buttons, then power. When the red led lights up, I unpress power, then the volume buttons, connect the USB cable and nothing happens on my phone (black display) red led still on. On my computer I see ZTE Handset Diagnostic Interface(DFU) (COM3).
Edit: I managed to get into EDL mode thanks to Axon 7 EDL Tool but I got a "File analysis: error" "not important files found" so I went back to MiFlash and also got an error about the files. Will update the post when I get it to work.

Glad to see you solved your issue. I misunderstood your problem. I thought you had access to the system and not to recovery or fastboot. Anyway, this guide is for unbrick or return to stock. I'll investigate the relock problem. Usually clearing devinfo partition should be enough to relock any bootloader.

In order to get access to fastboot I had to use the tool Axon7Toolkit, select "unlock bootloader" option, make sure you have an old version of MiFlash installed (20161212) and then you can select "lock bootloader" on Axon7Toolkit.
Thanks for everything.

Well, I am considering to link the older Marshmallow ROMs since the Nougat ROMs have some issues with fastboot. Anyway. It is going to take some time to test the alternatives. Thanks for letting us know!
Some of the most recent firmware for Axon 7 (@NFound's B12 bootstack, I think) doesn't support the EDL button combo. But if you have TWRP installed, you can boot to recovery, then reboot to EDL from there.
I kept getting the device registering in device manager in DFU mode. But I noticed that it briefly registers as QUSB_BULK before reverting to DFU. So I installed zadig winUSB driver and now it registers as QUSB_BULK when I turn on the device pressing all 3 buttons.
How can I proceed now?
Hi there
Thanks for this guide. I have a 2017U, so I got A2017U_B35_NOUGAT_FULL_EDL.zip file. After unzipping and connecting the phone to the computer it gets properly recognized and i can start the process from the MiFlash program. After reaching somewhere between 30-40% of the flashing process, it goes suddenly to 100% and it says that is finished. When I reboot the phone, it appears as if I was still under an unlocked bootloader (warning message + TUX penguin image) and the phone starts but during the initial setup process, i chose to start as a new phone but it says that "This device was reset. To continue, sign in with a Google Account that was previously synced on this device" and obviously this is not what I am interested for.
How can I get rid of this message and get a full clean install, with bootloader relocked and all that??
Thank you for any help you can provide!

There ate several ways to remove that. One involves TWRP 3.2.1-7 and the other Axon 7 EDL tool, if you dont have TWRP then use the second . Jusy go to the unlock menu and apply the google unlock.
A third way would be to setup the phone with your old google account and do afactory reset from within Android, not from the bootloader. That would remove also the owner safety.
Thank you so much for your guide and software bundle.
I even had to make a EDL cable to restore my device.
After flashing, I do not see vendor as a partition but looks like it is a folder. Is it OK for future ROMs ?
Hello,
Any root and custom ROM available for the Lenovo tab m8 tb8505 variant? The stock rom feels good for the price but if something better to make the tab feel nicer..
Thanks
I managed to root it for now, using magisk_manager.apk and a boot.img, I extracted from a file named "TB-8505F_S100133_200316_BMP.zip" (which is the latest firmware for the M8-8085F)
am unable to find any TWRP for the device.
but at least: got root now.
OTG and Charge Simultaneously
Hello,
I recently purchased the Lenovo tab m8 to replace the outdated navigation system in my car. I thought that since it came with a dock station that I would be able to connect the otg cable on the micro USB port. However this does not work, if it’s charging on the dock and I connect the OTG it stops charging. Does anyone know how I can die both things simultaneously?

@Xenograph:
Hi, would you care to specify in detail the rooting process used for your tb-8505F?
That would be very much appreciated!
I aquired the tb-8505X (LTE) model myself, but was surprised by not being able to dig up the rooting method specific for this model from the internet for two weeks now.
So far, my attempts to aquire root have got stuck at the initial stage of having my W7-64bit laptop communicate with TB-8505X via (first) ADB (lists the device) and (second) fastboot (no devices or waiting for devices).
My suspicion is that while ADB has at its disposal the correct W7-driver, subsequently fastboot is unable to operate with that driver.
Internet search shows the <fastboot-waiting for devices> to be rather common, but without coherent solution.
Any thoughts welcome, thanks!
Did you enable developer options and and there USB debugging and OEM Unlock?
I only plugged in mt 8505F, typed the command "adb reboot bootloader", waited until Windows installed the drivers and I was good to go.
After this started the root process
Cheers
Tom

Yes, enabled all three of them.
Then installed the ADB/Fastboot package on W7/X64.
Then the usb driver/drivers (don't know).
Then from the admin CMD adb list devices (returns device name)
Reboot tb8505 into fastboot mode.
adb>fastboot list devices (returns waiting for devices...)
Any other subsequent fastboot command returns the same ''waiting for devices''.
Could be this is better attempted from W10,Ios or linux.
Any thoughts? cheers!
I think its a driver problem, which adb/fastboot package did you install?
When you are in fastboot and you open your device manager, any device which shows an exclamation mark?
Cheers

Device manager shows Lenovo Android Interface again.
8505X shows usb debugging options back at 'No data transfer' again, which does that every reboot, so I reselect connect as Media device or as Camera after every reboot.

I am assuming the device shows it is in fastboot mode, its listed in Device Manager under Android Phone(?) as ADB Interface
After reboot it is listed fro me under USB Devices as ADB Interface. In fastboot boot the driver is from Mediatek, in working mode, the driver is from Microsoft
8505X shows usb debugging options back at 'No data transfer' again, which does that every reboot, so I reselect connect as Media device or as Camera after every reboot.

Used Developer Options to set the Default USB configuration to "File Transfer" works as I set it

Installed mediatek drivers for fastboot, to no avail.
Despite setting the usb preferences to file transfer, the 8505X resets that at every unplugging/rebooting to charging via usb/no data transfer, which also could be the problem, as before entering fastboot mode, usb is disconnected.
In fastboot mode no listing under USB devices in my dev mgr, btw.
Dev mgr shows Alcatel ADB Device>Lenovo Android Interface (as before) and moreover Lenovo Tab M8 under Portable devices. That's in normal working mode.
I presume you are on W10?

unlocked bootloader; no root
Hi,
managed to unlock the bootloader on TB-8505X by connecting it to an apple mac instead of W7. Worked via ADB and fastboot, without need to install USB drivers manually.
What would be the next advisable step(s) to take in order to achieve root?
I had a look @ the TWRP site, but there was no TWRP recovery offered for the TB8505F/X.
Any thoughts appreciated. Cheers!

1. Go to Lenovo site and download Rescue and smart assistant. Install and run.
2. On the rescue tab you can download the firmware for your tab (it needs to be connected to the PC).
3. Goto where you downloaded the firmware. In the RomFiles folder find the boot.img file. copy it to your device.
4. Install Magisk Manager on your device. Run and select install. select the option to patch a file and select the boot.img file you copied to your device.
5. markdown the location that magisk shows where it saved the patched file. Copy this file back to your PC.
6. Flash the file to your device with fastboot flash boot <patched file location>
7. reboot your device and run again magisk manager this should install the magisk zip file and you are rooted.
Is there any custom recovery and roms available? This tab is quite awsome

I'm looking for a custom recovery as well.
I am having problems with Fastboot. I tried all the drivers etc. and always end up with:
C:\adb>fastboot devices
(returns nothing)
C:\adb>fastboot reboot
returns < waiting for device >
Any ideas how to connect with Fastboot?
I want to replace my old Mediatek based tablet with one of these.
So i hope that there's a method to invoke Fastboot or Download Mode by other means than ADB.
While on all other devices i have to keep power Button plus vol up or down plus sometimes Menü Button pressed, my Mediatek tablet requires holding vol up or down while attaching the thing via usb, w/o touching power to power up into Fastboot.

Holding down the down vol while pressing power gets you to Fastboot mode.
That's the common method. Good. On my Acer you need to attach a usb cable even for accessing the stock recovery. But i will dump it anyway, a Tab M8 FHD has been ordered...

Hii XDA fellows,
So I have seen many people asking for noob friendly guide to restore original oxygen os firmware or basically unbrick device. There are several thread on this already but trust me I have tried them all and in my case I had to use my own brain. So I have compiled a noob friendly guide which I,myself have used to unbrick my device.
small warning this will wipe all of your data.
Firstly I wants to thank Some_Random_Username for bringing up MSM Unbrick tool for OnePlus Nord. His guide to unrick nord is also fairly good enough but in my case I was stuck in bootloop after installing a rom. My phone was not even booting to Qualcomm EDL Mode so that I can use MSM Tool.
Lets start with pre-requisites:
You must have unlocked bootloader.
Original Oneplus Type - C cable.
Windows PC.
ADB debugging turned on your phone.
Firstly Switch off your device, which I think most of you have already have as the device is bricked but in case your phone is stuck in bootloop or recovery or bootloader menu itself then try holding down voume up button and power button together hold them down till you get heptic feedback and screen goes off. Let it be cool down for about a minute.
Now Setup your PC:
Download MSM tool to from this guide : Click here
Setup adb environment in your PC if you havent already setup follow this guide
Download Qualcomm EDL drivers from here: Click here
Now download Unofficial TWRP recovery by Mauronofrio from here
On your PC right click on start menu icon and start Windows Powershell(Admin) and type this command bcdedit /set testsigning on This will turn off driver signature verifications on windows you will be required to restart your pc now after you restart your pc will boot into test mode and you'll see a watermark stating the same in bottom left of your desktop. Worry not we will undo this after we have finished restoring.
install Qualcomm EDL drivers by running the setup listed above.
Unzip MSMTool there you will see a file named MsmDownloadTool V4.0.exe run it, it'll take some time but after you see a pop up asking for user type user name and password, Select other as user type and leave other stuffs blank as it is and click next.
In the next window, In the target button select O2 while using global tool or India while using indian tool or EU when using european tool.
Now you have to boot into Qualcomm Emergency Download Mode
You can do this in several diffrent ways but one I am listing here is recommended :
Boot into fastboot/bootloader mode by pressing and holding Volume up, Volume down and power button together when you see a Menu pop up on your screen you can let go all the fingers at once.
Now connect your phone to your PC and go to that folder where TWRP recovery is located. Hold Shift button and Right click inside that folder you'll see an option "Open powershell window here click on it. In the powershell window type
fastboot devices and press enter your device will be listed as fastboot devices in powershell window. Now type
fastboot boot twrp1.img press enter
your device will boot up in TWRP recovery in twrp recovery go to reboot section and select Edl, This will boot your phone Edl mode your screen will go off as soon as it happens in the MSM tool window you'll see a device listed as com3/com5/com7.
Click on start button the restoration process will begin. Wait for about 400 secs and your device will automatically boot up.
Voila you've successfully unbricked your phone.
If you want to exit from Driver test mode on your pc simply start a powershell window with admin rights and type
bcdedit /set testsigning off
and restart your PC.
So first off all i want to say thanks for this guide.

Seems like it's a software issue probably a bug in your rom rich out to the developer he might help you, as you have tried both with Linux and windows i don't think it's a driver issue, it could be an issue with the hardware also but chances are pretty low for this to happen. Try flashing other roms if you have backup of your phone, use orange fox recovery it has an option of taking nandroid backup.

the thing is that i cant flash other roms, my phone dosn't gets recognized in fastboot, recovery and edl, so with the aex recovery installed i have no chance to change the rom without a pc, reached out to the dev but seems i'm the only person with the proplem, but thanks for helping.
Well, ok..I have a huge problem.
I was in developer mode and it said i could switch my rom so i installed it and now my phone says "Your device is corrupt. It is not trusted and will not boot".
Any suggestions on how I can fix this?
Wow that can't be good. I'm new to the oneplus stuff, normally I would say boot into recovery and reflash to stock but since we do not have roms yet I have a feeling your going to have to take it back to tmobile or oneplus and exchange it.
He should still be able to recover it with a factory restore via the stock recovery. As far as I know (and I'm not an expert) a bad ROM flash doesn't touch the recovery partition.
from https://www.devicesfaq.com/en/reset/oneplus-nord-n200-5g
Restore with hard reset or Recovery mode OnePlus Nord N200 5GRestore with hard reset or Recovery mode your OnePlus Nord N200 5G can solve problems that have not been solved with a normal factory reset.
1- First turn off your OnePlus Nord N200 5G completely. If you can not unlock the screen, press and hold the power button for about 20 seconds and the phone will turn off.
2- Keep holding on volume down and power keys together for a few seconds in your OnePlus Nord N200 5G. In some devices according to the Android version the combination can be the power key and the volume key up.
3- When the OnePlus logo is displayed, release the buttons.
4- Move through the menu with the volume up and volume down keys until you reach the “Recovery Mode” option and press the power button to access.
If the device menu appears in Chinese characters, click here to see how to reset a mobile in Chinese
5- Use the volume up and volume down keys to select the “wipe cache partition” option and press the Power button to activate the option and clear the mobile cache.
6- After a few seconds you will return to the previous screen, with the volume buttons go to the option “wipe data / factory reset” and press the power button to enter. A screen with many NOes and a YES will appear, with the volume keys again go to the YES and press with the power key.
7- After finishing again with the volume keys, click on “reboot system now” and press the power key of your OnePlus Nord N200 5G, the device will reboot and take several minutes to start while restoring the device to its factory state and optimizing the applications pre-installed in the system Android 11, OxygenOS 11.

I can't even get into recovery. I can get into download mode but theres no way for me to restore it from that...
literally recovery mode is gone also. it's so weird, i did this from my phone's settings, it shouldn't have done this.

phone off -> volume down + power (hold both in until phone's booted)
that doesn't work to get into recovery mode?
How about
volume up + volume down + power
to get into fastboot mode?
Can you connect via USB to run ADB commands?

I can only boot into fastboot, recovery just boots back to "your device is corrupt'.
I can connect usb but i can't find drivers for the phone, its connect as QUSB.
Get the Google USB Driver | Android Studio | Android Developers
The Google USB Driver is required to perform adb debugging on Windows with Google devices.
developer.android.com
There's the USB drivers.
Selecting recovery from within fastboot mode brings up the corrupt message as well? Very odd.
I'm seeing 2 options then. Take the phone back to the store you got it at to see if they can fix/replace it; or wait for the ROM to be released.

I've installed these and it still comes up as qusb bulk.
Yeah, selecting recovery from fastboot goes to corrupt message, too.
Just going to make a aservice request.
There was another report of this on the OnePlus forums a while ago, too, if I'm inferring what happened correctly: https://forums.oneplus.com/threads/...-the-oneplus-nord-n200.1460001/#post-23393026
The only real recourse right now is to submit a ticket as you've done and wait until you can send your device back and they send you a new one.
Once OnePlus releases a full stock ROM image, if they ever do, it will be possible to recover a bootloader-unlocked device from this state. But even then that won't work if you weren't bootloader unlocked beforezs the update.
---
While you've still got the device, though, could you try something for me? Could you install the android platform tools, see if you can get fastboot working on your computer, and try the fastboot command "fastboot set-active a"?
The Nord N200 5G is a A/B partitioned device, which means it has two of each system partition, one labeled "a" and one labeled "b". The update process is *supposed to* install all updates into the partition that you aren't currently using, then instruct the system to switch to it so it can update seamlessly.
I have no idea what went wrong in your update process, but if it did an incomplete update then instructed the system to use the other partition (and now for some reason doesn't switch back) this could help. I kind of doubt it will, since in my attempts at flashing bootloaders, if I put anything fully invalid in boot partition 'b', the phone automatically switches back to 'a' and boots into "safe mode".
But if for some reason it isn't corrupted enough to trigger that, maybe switching back to the "a" partition set could fix it. Or if you're already on "a", you could try switching to "b".

Can u give me a link to platform tools, also..my computer is detecting the phone as QUSB BULK:"
From one of my other threads:

USB DRIVERS
You may need to use the Google USB Driver from Android Studio to allow your PC to recognize your phone when it's in fastboot mode.
Download Android Studio & App Tools - Android Developers
Android Studio provides app builders with an integrated development environment (IDE) optimized for Android apps. Download Android Studio today.
developer.android.com
Android Studio won't install the USB Drivers by default, you'll need to install them through the SDK Manager (Android Studio -> Projects -> More Actions -> SDK Manager -> SDK Tools -> Google USB Driver checkbox -> Apply)
You'll need to manually install the drivers through the device manager while the phone is in fastboot mode and connected to the PC (right-click -> Update Drivers -> Browse Computer -> Let Me Pick -> Have Disk).
The drivers should be located at:
C:\Users\[username]\AppData\Local\Android\Sdk\extras\google\usb_driver\android_winusb.inf
You'll want the 'Android Bootloader Interface' driver.

From the first update drivers dialog (your phone should be in fastboot mode):
"browse my computer for drivers"
"let me pick from a list of available drivers on my computer"
"have disk"
And the drivers should be at
Code:

Your phone is in EDL mode, also known as hard brick. It seems like the phone thinks both of your system partitions are empty or corrupt, as well as the bootloader is perhaps corrupt, due to which it is now gone to EDL mode as a last resort.
Typically, the only way to come out of it is to flash in EDL mode using MSMDownload Tool. Unfortunately for you, I don't see that Oneplus has released the MSMDownload Tool for the N200.
There are 4 things you can do at this stage.
1. If the phone is in return period, get it exchanged for another one.
2. Assuming the phone is under warranty, get it repaired under warranty
3. Wait for Oneplus to release the MSMDownload Tool for the N200. From past experience, Oneplus has eventually released it for every one of their phones. Once it is released, it is literally a 5 minute fix to get your phone to factory refreshed stage.
4. As a long shot, we can try to see if the bootloader is not corrupt, and if that is working, try to check if either of the 2 system partition is still intact, as @edale1 is suggesting above. Try the following
a. Press Volume Down+Power when phone is power off stage, and see if you can get the phone in fastboot mode.
b. Go to the folder when you have downloaded the Android SDK Toolkit. Alternately, search for the folder containing "fastboot.exe" on your hard drive. Open a command prompt in that folder containing fastboot.exe.
c. Run "fastboot devices" in the command prompt.
d. If you get a response of "no devices", then that means either phone is not in fastboot mode ( Go to Step a and repeat a,b,c until it is in fastboot mode) or bootloader is corrupt (nothing can be done other than Steps 1, 2 or 3 I have outlined above)
e. If you get a response of "XYZ fastboot" where XYZ is a random string/number, then bootloader is not corrupt. Proceed to Step f.
f. Type "fastboot getvar all" in the command prompt.
Wait for a lot of text to finish scrolling and look for the (bootloader) current-slot text
This should actually be toward the bottom without the need to scroll up.
The letter after this text will be the currently active partition slot for your device, either 'a' or 'b'
g. Follow @edale1's instruction above to change active partition to the *opposite* of whatever currently active partition e.g. if it says 'a' as the active partition in Step f above, then type in "fastboot --set-active=b" in command prompt, and vice-versa i.e. if it says 'b' as the active partition in Step f above, then type in "fastboot --set-active=a" in command prompt
h. If you get success in Step g, type "fastboot reboot" in command prompt, and keep your fingers crossed that it boots up normally. If not, that means both system partitions are corrupt. Follow Steps 1, 2 or 3 above.
Good luck!

If you didn't enable OEM unlocking in developer options before you bricked your phone, you can't unlock those fastboot commands.
