If you like our forums, you probably like tinkering with your smartphone. OnePlus smartphones are some of the best for modifying, with even the T-Mobile variant of the OnePlus 6T being relatively open compared to other options from US carriers. Even still, modifying your device is not without its risks, and it can lead to you temporarily bricking your phone. Generally speaking, this is why companies release factory images for devices so that users can rescue their phone themselves. OnePlus does that, but they also have a tool called the “MsmDownloadTool,” which customer support representatives use to flash your device entirely back to stock in order to troubleshoot a problem. This tool has been released, and you can use it to flash your OnePlus 6T (including the T-Mobile variant) back to stock.

It’s a pretty simple program to run, and there isn’t a lot of set up required to rescue your phone. Just make sure it’s switched off, then hold down both volume up and volume down when plugging your phone back into your PC. Your phone will boot into Emergency Download Mode (known as EDL), which will let you flash signed partition images. If your phone doesn’t show up in the tool, then you’ll need to download the drivers linked in both posts as well. Once it connects, simply click “Start” and you’re good to go.

Keep in mind that this program will wipe your phone, but it will also re-lock your bootloader as well. That’s not such a big deal, given that you can easily unlock again, but it’s worth noting. Thanks to the openness of OnePlus devices, it’s a pretty easy process to unlock your bootloader and root again. If you’d rather not jump through hoops installing software, it’s also possible to boot a recovery through fastboot and flash your device back to stock manually. This tool is really only for completely wiping your device and starting over fresh.
