calvinistmac, Jul 21, 2016 : Here is version 2.0.1 of this guide! VERY IMPORTANT, PLEASE READ!!! These instructions will work with all current versions of OOS 4.0 and above, and Open Betas 11 and up. I am not supporting the earlier Open Betas with this guide simply because you shouldn't be running them at this point as there is no need. If you are running an earlier Open Beta and want to unroot and keep that Open Beta you do that at your own risk. I am also not supporting MM any longer with this guide as all of the recoveries have changed around, which can cause headaches. IF YOU HAVE A 3T, THESE INSTRUCTIONS WILL WORK, BUT YOU MUST DOWNLOAD THE 3T FILES, NOT FILES MEANT FOR THE 3, OR YOU WILL BRICK YOUR DEVICE. DISCLAIMER: I am not responsible for bricked phones or lost data. Please do the appropriate backups of your data and read all of the instructions posted here before you attempt. If you aren't comfortable doing this then don't do it. MORE INFO: If you post here asking for help (which is fine by the way), I may or may not be able to help you. I don't have your phone in front of me to help you troubleshoot and I cannot magically fix it over the airwaves. If you follow my steps to the letter you should be fine. Make sure you don't skip anything, and please read the DISCLAIMER again for good measure. I've had a lot of posts asking for help and I can't help everyone unfortunately. EVEN MORE INFO: I don't look at this thread all day, every day. If you're asking for support from me and don't get it right away that's the reason. I'm sorry for any inconvenience but it's the way it works. I'm a stay at home dad so that takes up most of my day. I do check it when I can though. Again, sorry if any inconvenience has been caused by my lack of appearance and posts here. WHY YES EVEN MORE INFO: If you want to downgrade back to MM it's beyond the scope of this guide. I may make a guide to detail how to do that at another time. There are instructions floating around these wonderful forums about how to do that. UNROOTING INSTRUCTIONAL VIDEO (courtesy of @ritchiedrama ): That being said, here are the instructions (all commands are typed on a computer using a terminal app (Linux or Mac), or Command Prompt in Administrator mode (Windows)): 1. Download the current OxygenOS (Stable or Open Beta) full zip from the OnePlus support site: http://downloads.oneplus.net/ PRO TIP: rename your downloaded file to ota.zip, it'll make typing the commands a bit easier. If you have a OnePlus 3, then download the OnePlus 3 files. If you have a OnePlus 3T, then download OnePlus 3T files. 2. Download the stock recovery for your device: http://oxygenos.oneplus.net.s3.amazonaws.com/recovery_op3.img - OP3 Recovery http://oxygenos.oneplus.net.s3.amazonaws.com/recovery_op3t.img - OP3T Recovery 3. Boot into Fastboot Mode (I believe it's power and volume up, or use the extended boot menu from Android to boot here) 4. Fire up a terminal app or the Windows Command Prompt in Admin mode and make sure you're in the folder/directory where you downloaded the above files on your computer. 5. Type: fastboot devices -- Just to make sure everything is working. If you see a serial number you're golden. If not check all of your drivers (mostly Windows users will have this issue). There are threads on how to install the drivers within the forums. If you use Linux or a Mac you should already know how to get the proper files on there. 6. Type: fastboot flash recovery recovery_op3.img (or recovery_op3t.img if you have a 3T) -- This will flash the stock recovery back to the phone. 7. Type: fastboot oem lock, then follow the prompts on the screen. This will erase the phone. The phone will boot into recovery with chinese characters and wipe the phone clean. When it's done it'll reboot, the second you see that happen hold Volume down to boot into recovery again. If you don't it'll be in an endless bootloop. ** 8. Boot into recovery by holding down power and volume down. It'll boot into stock recovery. 9. Choose english as the language, very important 10. There'll be an option to upgrade via sideload. Choose that option. This will put the phone into ADB sideload mode. 11. Type the following: adb sideload ota.zip 12. Go grab a cup of coffee or two. It'll take a bit. 13. Once it's done reboot the phone. The option will be there once the sideloading is done. Just select Reboot and press the power button. 14. It should boot into stock, unrooted OxygenOS. Congratulations you did it! Enjoy your stock, unrooted device! ** After you do the fastboot oem lock command and it erases the phone & reboots, it may bootloop once and then go dark. If that happens hold down the power button until it reboots, or hold down power and volume down until it reboots. It's normal.
