Pixel phones are always good because theres no hoops to go around to unlock it and root. Also to get root use this thread for in2017(tmobile) model: https://forum.xda-developers.com/t/guide-android-11-how-to-root-t-mobile-op8-5g.4228303/


For verizon use this thread: https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4191723/
Not so much... If you buy a Verizon Pixel it will be locked until an exploit is found. If you buy a T-Mobile Pixel you will still have the same Network Unlock crap that all T-Mobile phones have.

If you buy straight from Google, yes, its full unlockable from the factory.

Anyone try using this tool on Android 11? I can't receive MMS/SMS messages.

UPDATE: I was bootloader unocked & rooted on Android 11. The tool was able to revert my phone back & my messages are working now. It put me back on Android 10 & i will root my phone back again. Thank you for this tool!

Hi everyone, similar to the previous threads for
OP3, OP3T, OP5, OP5T, OP6, OP6T, OP7, OP7PRO, regular OP7T, T-Mobile OP7T, regular OP7TPRO, T-Mobile OP7TPro 5G, regular OP8 and OP8Pro here is the EDL package (also known as MSM tool or unbrick tool) that can revive a bricked OnePlus 8 bought from T-Mobile.

It will only work with T-Mobile variant IN2017

You should also be able to rollback your phone to a previous release of OOS with them if for some reason you want to go back to an older firmware :)

You can download the following versions:

ANDROID 10:

OOS 10.5.7
OOS 10.5.20: Gdrive - AFH (credits to @rzracer2 )
OOS 10.5.21 (credits @LLStarks for finding it)
OOS 10.5.22 (credits @LLStarks for finding it)


Mirror for first and last MSMs: https://onepluscommunityserver.com/

Instructions:

Launch MsmDownloadTool V4.0.exe.

On the login prompt select "Other" in the dropdown menu and click on Next.
Wait a few seconds until main window shows up.

Click on Target button and select TMO.
Press Start button so that it waits for your device to be connected
Power off your device
Maintain volume up and down buttons to get into Qualcomm EDL mode.
Plug your device to your computer.
Should you not manage to do that and have adb access, you can use adb reboot edl instead
Wait ~300 seconds.
Enjoy your brand new device.

FAQ:

Does this work on Mac or on Linux?

Unfortunately no, tool is Windows only. You should need at least Windows 7.

Why is my antivirus freaking out when unzipping the archive or running the tool?

In an effort to protect reverse engineering from being done (and by extension prevent conversion process like it was done on 6T and 7Pro), OnePlus now use VM Protect V3 in their MSM tools. As this tries to detect debug environment, this is seen as malicious behaviour by some antivirus.

My device isn't detected

Go to device manager and make sure your phone shows up as QDLOADER 9008.
If it shows up as QHUSB_BULK, it means Qualcomm driver wasn't installed automatically by Windows Update. Download the latest one from Microsoft website at http://download.windowsupdate.com/c..._fba473728483260906ba044af3c063e309e6259d.cab (source https://www.catalog.update.microsof...updateid=8ee52ba0-bdef-4009-88cf-335a678dd67a ) and install it manually by right clicking on QHUSB_BULK and selecting "Update driver software" and "Browse my computer for driver software" to where you downloaded CAB file.

If you can't get into EDL mode by hardware keys, you may use adb reboot edl (will require your phone to still have ADB access)

MSM tool is stuck on "Param pre-processing"

Ensure you're using the Qualcomm drivers linked above.

MSM tool is stuck on "Sahara communication failed"

Unplug your phone, get in fastboot mode, turn off phone, wait 15 secondes and get back in Qualcomm EDL mode. You can also try using a USB 2.0 port instead of a 3.0 one.

What is SMT Download mode?

Just don't try to unlock that mode, it will wipe your IMEI and your Widevine certificate if you use it.

How can I fix "SMT config not found" error?

You can't MSM TMO to global. That tool is only for use to come back to stock if needed. Use this thread and download the global from there. Happy modding!

Just wanted to say thank you for this tool and guide. Had an issue with a used T-Mobile OnePlus 8 that was on March software update 11.0.1.2.IN55CB. System update showed a new August update was available but it would fail to install after numerous attempts and resets. Used the tool to return to Android 10 and was able to update successfully.

Am hoping someone here can help me. I have an unlocked bootloader on my OP8, and was trying to flash a different rom, but it is bricked-- phone boots to crashdump mode. When I hold vol up + power to hard power off, it reboots and does not power off. This is not a result of me holding the power button too long. I release all buttons the instant the screen goes black. But instead of staying powered off, the screen stays black for about 2s and then does a little 'vibrate' and powers back on again. The result is that I can't completely power off the device in order to put it into EDL mode. Other things I've tried: releasing power and then holding down vol up + vol down the second the screen goes blank and plugging in the usb cable to a USB 2.0 port before the little vibration indicating power on occurs (this took me 30m of trying to pull off because that's a lot of things to do with two hands in less than 2s). This causes the "Fastboot" boot graphic to appear for less than a second, whereupon it goes straight back into crashdump mode. I have also tried booting straight back into fastboot mode-- same result: flashes the Fastboot icon briefly and then goes straight to crashdump mode. The only thing I have left to try is letting the power completely run out and then trying to enter EDL mode. I'm really hoping someone has some advice for me because I have no idea what else I can do. If anyone can tell me something that works I'll gladly paypal you some drinks funds. :(
Edit to add: also, I am using the stock cable. I let it run out of power overnight, but when I hold down vol up + vol down and plug it in, nothing happens. MDM is definitely open, but nothing shows up in device manager. If I press power, it shows a display for like 2s that there's not enough battery left. If I let it charge long enough to get enough battery to start, it powers on automatically and starts the crashdump mode all over again. :(

Try while plug in usb cable on phone, holding vol + & - and power botton until phone reboot.
Check on windows device manager weather your phone ia in corret driver. It will show in device manager on port 9008. If not, try install the driver attaced OP.

Yeah, I tried that. It never installs anything or shows up in device manager at all until after it shows the crashdump screen. When it reboots, it never goes to EDL mode at all or even tries to. Instead, it immediatley tries to enter fastboot, fails, then switches to crashdump. I tried forcibly installing the 9008 driver over the 900E driver it installs when in crashdump mode, just to be sure. If I reboot while holding +/-, it shows it offline in device manager. The phone then vibrates. It shows fastboot for less than a second. It then goes straight into crashdump mode, and _only then_ does it show up in device manager. So in other words, EDL and Fastboot devices aren't showing up in device manager at all, period, because Windows isn't even detecting anything as connected until it hits crashdump. Thanks for trying to think of something though =/

I facing this problem before, on crashdump mode while cable still plug in. Press and hold vol + & - and power button ( must assure USB cable is plug in PC) . After phone reboot, hold on button until PC detect your phone ( watch on your device manager ). Because edl mode is blank screen, nothing will show on phone.

So I know that I'd tried this the first 50 times before looking really, really carefully at everyone's advice to get it powered off and only then hold volumes and plug in (no power button). However, I literally received a brand new OP8 for my wife in the mail today. It also came with a brand new OEM cable. When I used *that*, it worked, and the MSM tool saw it. For anyone else encountering this problem, please consider buying a new cable. Mine was about a year old and I think it may have been damaged just enough to cause issues, even though Warp charge was still working with it.

So, everything was going well in MSM, but my computer ran out of battery while it was running, is my phone completely bricked? It seems like it.

I cannot believe I made this mistake, not plugging in my laptop, I'm super pissed.

    I'm still having trouble booting to EDL, I've tried the volume buttons, adb command, and fastboot command, but none have worked for me. When trying the volume buttons it just brings me back to fastboot mode. I don't know what else to do.
    Ah yes. I had an "issue" there as well. I'll elaborate and try to make it easy.
    1. launch your msm tool and connect ONLY the end of the usb that plugs into your PC
    2. Power off your phone all the way.
    3. While holding down both the volume up and down keys (I use my right hand for the volume buttons), I use my left hand and plug the phone into the usb cable.
    4. MSM tool "should" say connected after your computer gives you that "ding dong" windows sound.
    5. Click on connect and click start. DO NOT TOUCH THE PHONE UNTIL IT REBOOTS ITSELF. (caps for emphasis)
    6. for good measure, I reboot the phone back into recovery and wipe all sections, meaning these 3 sections: system setting, cache, and pictures, music, etc. I wipe all three sections 3 times to delete and wipe all old stuff so that you phone boots up clean.
    7. Let me know how it goes. Yes, lots of info here but I want to give you a clean write-up and nothing half-assed. It's just the way I work. <thumbs up>

    is yours TMobile edition?

    Yes, it's the T-Mobile version.

    These are files I have in my system to "unbrick:" my device:
    1. OnePlus 8 T-Mobile 10.5.7 -- unzipped the file before you proceed (you all knew that)
    2. QUD.WIN.1.1+Installer-10037.3+Setup -- this is required. If need this, copy and paste this in google. These drivers were hard to find at first. Unzip the download.

    3. OnePlus_USB_Drivers_Setup -- I thought these drivers were unnecessary but they are VERY necessary. (caps for emphasis)
    4. When you have unzipped the QUD.WIN.1.1+Installer-10037.3+Setup file and the OnePlus_USB_Drivers_Setup, go through the setup wizard. NOTE: Oneplus will ask you for something like "Wincom" for something of that nature, click next. It threw me as well. When the drivers have all been setup up and installed, perform a reboot to refresh Windows (it's good practice especially when dealing with drivers.

    Guys who are having trouble: This is what I did. I powered off the phone completely. Launch the msm download 4.0. When the dialog box comes up, get your phone ready. When the phone is completely off, press and keep the volume up and down button pressed. Plug the small part of usb into the phone. While holding the volume up and down buttons and phone steady, I plugged in the fat end into the other usb port on your computer since we're dealing with unbricking our phone. You will know when connection is made when you hear the windows "attached" sound and you will see a "connected" text in the field on the top in the msm download tool launch box. Click on the connected to highlight this and click start. Do not play with your phone during this time. Let the program do its thing and your phone will automatically reboot when done.

    I hope this helps guys. Wordy yes but it beats being confused as hell....

    I have a T-Mobile OnePlus 8. I let my ex-girlfriend use it and she put a fingerprint on the phone. When I start the phone up, obviously it asks me for her password to get into the phone (not to start Android) if I use this tool is it going to completely reset the phone to the point where I don't have to put in her Gmail after I reset the phone? That's how it works with the 7 Pro. not sure if it is the same here so just wondering if somebody could confirm or if anybody had any idea? Thanks

    That's how it generally works, unless they've changed something this gen, which is unlikely.

    Thanks. Your steps are really helpful. just want to share my experience of connecting the phone. If you plug in your USB cable before installing drivers, you need to unplug it after the drivers installed, so the MSM can detect your phone.
