Unfortunately, you will 'fall into the rabbit hole' of having either OOS issues or potentially bricking your device. The Verizon OP8 5G UW is very finicky of which type of ROM you decide to flash on it and what will actually stick due to hardware changes within the device.

Tried this unlock method on my IN2019 with both the Android 11 and 10 MSM tools and found that you're most likely going to find more success using the Android 10 MSM tool to flash unlock. Android 11 MSM throws a crashdump at me when updated to the latest ota while the Android 10 MSM (also updated to the latest ota) worked just fine. Just a tip for those who might have ran into the same problem as I did.

Android 10 MSM Tool: https://onepluscommunityserver.com/list/Unbrick_Tools/OnePlus_8/Verizon_IN67CD/Q/
*Also make sure you flash stock.ops before flashing Android 10 ops! https://retry.abort.fail/vzwunlock/stock.ops

How do I get back on IN2019 with bootloader still unlocked? After unlock my phone is on IN2020 and can’t get security updates. Now the phone is stuck on dec 2020 security patch but was on a 2022 patch before unlock. I also tried flashing the stock Verizon firmware but get a model mismatch.

Unfortunately, you would have to use the MSM Tool and start from Android 10 and start from scratch because the MSM Tool for Android 11 is causing issues for some folks.

Re-download and re-install all of the OTA updates.

So I should flash android 10, unlock boot, then update to 11? Thank you by the way, much appreciated.

    Figured that much, thanks for verifying. Would you happen to know about freeing up storage on these phones? Android 11 is using 22gb of system. I read android 11 is supposed to use more because of the 2 slots. Would I beable to format slot A and extend it to slot B and gain more storage or does android 11 need the second slot? Figure these are computers, so like in Ubuntu you can created multiple partition or one partition. Sorry for all the questions just switched from iPhone so trying to make sense of the new android lol. Had a Sam s8+ and note back in the day but it seems a lot has changed since android 9.
    Seems like a lot more work than it's worth to repartition.

    You are free to enter this rabbit hole and cross your fingers and your toes.

    N.B.: There is a method to resize partitions via TWRP. Feel free to utilize Google Search to further info.

    Fixed- Though may want to add it to the notes and additions section.

    If you flash the unlock ops incorrectly it will break the bootloader.

    I was able to do this whole process successfully on windows 11 with USB 3.0 using the ADB EDL command
    Though after bricking the device I could not get into edl mode (assuming USB 3.0 takes to long to register the device not triggering edl mode with using the vol= & vol- keys).

    So if you brick the boot loader please make sure you use USB 2 and the key combo to get into edl then you can flash the stock.ops.

    After flashing the stock ops I had to go back to USB 3.0 as I was getting a communication issue to install "instantnoodlev_15_O.01_210110.ops"

    Hope this helps if someone has the same issue as I.
    After reading your post and findings - it almost seems impossible to totally brick as long as you have a working version of MSM and utilizing the correct key combo.

    lol, somehow I have cell data. The first time I flashed I did not but I think I used MSM for the entire process and do now.

    For me, it was all in MSM 10 based on Rodkens suggestions (though not sure that is what he intended)

    -Fash stock ops
    -Flash OS 10
    -swap ops file in MSM 10 to 11 ops
    -then swap in unlock ops

    I am using cherish OS on the OP8 and have full working cell service.

This method also will wipe your phone, so please back up your data. I also will disclaim any understanding as to why exactly this works, since this method was developed by someone else, I am just listing the instructions on how to use it. With that being said, understand your personal limits and read this entire guide before starting.

    Preface

    I have seen dozens of posts asking for a Bootloader unlocking method for the OnePlus 8 5G UW (IN2019) and thanks to the attributed users at the end of this post, a method has been found. I will document the most straightforward way to unlock the bootloader here so you can install custom OSes, TWRP, and Magisk.

    Part I: Prerequisites and initial setup

    To follow this guide you will need
    • A Windows PC (running 7+)
    • Latest MsmDownloadTool and stock firmware for the OnePlus IN2019 - Link
    • OnePlus 8 IN2019 with latest stock software update and USB cable
    • Latest version of platform-tools - Link
    • The bootloader unlock.ops file - Link
    Plug your phone into your PC using a USB 2.0 port (this is important, USB 3.0 has given me a lot of issues and just doesn’t seem to work all the time) and ensure USB debugging is enabled.
    Extract the downloaded platform-tools zip and open the platform-tools folder in a command prompt, and Run adb devices and makes sure your device appears in the list.
    Next, extract the OnePlus_8_Verizon_OxygenOS_11.0.zip and open up the MsmDownloadTool V4.0.exe inside the instantnoodlev_15_O.01_210110 folder.
    When the application opens, select “Others” under the User type dropdown and hit next. Leave this window and the platform-tools command prompt open.

    Part II: Entering Qualcomm EDL mode and installing correct QDLoader Driver​

    In this section we will install the correct drivers to utilize Qualcomm's Emergency Download (EDL) mode. When you are in EDL mode, your phone screen will be completely black and it will only exit if you complete a flash or unplug it from your PC and hold volume up, volume down and power. To enter EDL mode from a powered off state, hold volume up and volume down and connect your phone to your PC.

    1. Return to the platform-tools command prompt, and type adb reboot edl and wait. Your phone should disconnect from the computer and then reconnect.

    2. Open Device manager, and check for the device “Qualcomm HS-USB QDLoader 9008” or “QUSB_BULK_CID:xxxx_SN:xxxxxxxx” - if you see “Qualcomm HS-USB QDLoader 9008” under Ports (COM and LPT), skip to part III. If you see “QUSB_BULK_CID:xxxx_SN:xxxxxxxx” under Other Devices with a yellow triangle, then proceed to step 3.

    3.
    Open Settings, Go to Windows Update and Check for updates. After, Click Advanced options, Optional Updates and drop down “Driver Updates” Locate “Qualcomm Incorporated - Ports - 3/25/2016 12:00:00 AM - 2.1.2.2” in the list, and install it.

    On Windows 10 - Open Settings, Go to Update & Security, Check for updates, Click “View Optional Updates” and select “Qualcomm Incorporated - Ports - 3/25/2016 12:00:00 AM - 2.1.2.2” and install it.

    This should install the correct driver, replacing “QUSB_BULK_CID:xxxx_SN:xxxxxxxx” with "Qualcomm HS-USB QDLoader 9008" in device manager.

    Part III: Flash Stock Firmware​

    In this section, we will flash the stock IN2019 Android 11 firmware. If you have any trouble with this process refer to the original guide on how to do this here.

    1. Return to MsmDownloaderTool and hit the Enum button. In the list, it should list the COM Port associated with the device. The status of connection should read “Connected”
    1646087693597.png
    2. Click the “Start” button. This will flash the stock firmware, wiping your data. Make sure you have backed your data up at this point. It will take a few minutes, usually ~300 seconds. Once it completes, it will reboot into factory default android.
    3. Close MsmDownloadertool and once you are back to android, unplug your phone and power it off.

    Part IV: Unlock the bootloader​

    In this section, we will flash the unlockable firmware and unlock the device for good.

    1. Inside the directory with MsmDownloaderTool V4.0.exe, there should be a file called “instantnoodlev_15_O.01_210110.ops”. Remove it from the directory, either by deleting it or moving it to another folder. Then take the unlock.ops file downloaded earlier, and drag it into the directory. It should be in the same folder as MsmDownloaderTool.

    2. Reopen MsmDownloaderTool V4.0.exe and like before, select “Others” in the drop down, and click next. Leave the window open.
    3. Hold in the Volume up and down buttons, then plug your phone back in. Keep holding the buttons until your phone connects to your PC as "Qualcomm HS-USB QDLoader 9008", like before. Check device manager to ensure that it’s connected correctly as a COM port. If it boots to android, power it off and try again.
    4. Return to MsmDownloaderTool and click Enum. Make sure the phone is still displayed in the list under the associated COM Port.
    5. Click start. The flashing should take about 15 seconds, and when complete, your phone should restart. It will display a message at boot saying “<!> The device is corrupt..” Do not panic, this is normal.
    6. Unplug your phone and hold Volume Up, Volume Down and Power until the device reboots and let go once it shows the OnePlus Logo and “Fastboot Mode”. You should arrive at a screen that has “Start” in big green letters at the top, and “Fastboot mode” below it, with the very last item saying “Device state - Locked” in red text.
    7. Plug your phone back into your computer, and open device manager. Look for the “Kedacom USB Device” category with “Android Bootloader Interface” under it. If this device is present, skip to step 9. If this device is not, proceed to step 8.
    8. Go back to Windows Update, Check for updates again, go into Optional Updates and install “Google, Inc. - Other hardware - Android Bootloader Interface”

    WN6xvg6PnYjr-Q1rhEvZAEgSCgwpmJCf8Oxa47UUTs-ZkLu2V_u-O850p5ql2FLr41DPTXmeFO5I0I8qY0o679yOfvW7OZLrzz-T3dyuZPZJHWCgTyKdDNXHBsv39Ku3_MmDrkpc
    Check device manager to ensure “Android Bootloader Interface” is present under Kedacom USB Device.
    1646088419023.png
    9. Return to your command prompt window open in platform-tools, and run fastboot devices and ensure your device is in the list.
    10. Finally, run the command fastboot flashing unlock and on your phone, it should prompt you to confirm unlocking the bootloader. Once complete, it should reboot into Android.
    11. Shut the phone off again, and then Hold Volume Up, Volume Down, and Power and let go when the OnePlus logo and “Fastboot mode” shows up on screen. If the final item in the list says “Device State - Unlocked”, Congrats! You have successfully unlocked your bootloader. You can follow your custom OS’s installation guide from here.

    Part V: Troubleshooting, Notes, and Attributions​

    Unplug your phone, and hold Power, Volume Up, and Volume Down. It should reboot into fastboot mode. Using the volume keys, navigate to the "Power off" option and hit the power button to confirm. Then holding Volume Up and Down, plug your phone back into your PC and try flashing again.
    • Any attempt to use MsmDownloadTool after the unlock will cause the device
      to become locked again. You can unlock again by repeating the steps above.
    • Attempting the unlock process while running android 10 will result in a
      crash at bootup. Update your phone to the latest update before starting.
    • USB 3.0 has thrown some obtuse errors when trying to use this process, so I highly recommend using a USB 2.0 port if possible.
    • If you want to flash back to stock firmware again (relock bootloader), you have to first flash this file (stock.ops) and then flash the bundled stock firmware. It will give a mismatch error if you do not.
    • You can only have one .ops file in the MsmDownloadTool directory at a time. You'll get an error if there are multiple files.
    If for some reason, you run into an issue or skip a step by accident, leave a comment and I will try to help as much as possible. This is my first XDA guide and I just wanted to compile something that would have saved me hours of trial and error.

    The unlock.ops link doesn't work?!?
    Right click the link and open in new window, than refresh the blank page it opens. That will trigger the download.

    Did you follow the guide while unlocking your bootloader and if so, do you have any feedback for the guide? This is my first guide so I just wanted to hear any potential criticism.
    It worked for me. It was straightforward, and it was really easy to figure out. I kept getting an error during the parameter update when I used the included firmware, so I just flashed the Unlock.ops file and carried on. I had a dumb moment bc I didnt actually read it fully at first, so I freaked out and thought that I'd bricked it lmao. But all in all, it was good man. Good instructions, and you gave examples that helped me out when I was confused. Good job! Well worth the wait

    Thanks guys. I'll be trying this soon.

    Can we use with another Sim when flashed custom Rom?? Anyone know??
    Yes. As long as your device is unlocked (60 days after initial purchase from Verizon) then it will work with any SIM.
