How to Root OnePlus 3/3T

Rooting OnePlus 3 and OnePlus 3T is pretty easy. The rooting procedure of 3/3T can be broken down into 3 steps, Unlocking the Bootloader, Installing TWRP Recovery & finally installing SuperSU to gain root access. Each new step relies on the previous step to have been completed, and a basic summary of each part is:

OnePlus 3/3T: How to Unlock Bootloader | Flash TWRP | Root

Stage 1: Unlocking Bootloader: Unlocking bootloader is the first step to rooting and flashing custom ROMs. The bootloader is a code that tells your device’s operating system how to boot up. In order to avoid any system modifications, manufacturers lock their firmware. In order to install any 3rd party files into your system, you need to unlock the bootloader.

Stage 2: Installing a Custom Recovery: Stock recovery doesn’t allow any installation of 3rd party zip files. In order to install any other zip which is not signed by the firmware manufacturer, we need to install TWRP Recovery. TWRP is a powerful tool that gives control over the phone without needing to boot into Android. It can be used to flash a ROM or use minor app mods, as well as to create and manage backups.

Stage 3: Rooting: SuperSu is an app that grants you Administrator rights (called “root access”) to run or install specific apps restricted by the Android Operating System for security concerns.

After completing these steps, your phone will be rooted, the phone will have a custom recovery installed, and the bootloader of the phone will be unlocked. This, in our opinion, is the most practical and beneficial method for rooting your phone. It gives you some basic ADB/fastboot knowledge, and should hopefully help you have a decent understanding of what is going on. Also, this method will work regardless of what android version your phone has.

Step 1. Download SuperSU & latest dm-verity and force encryption disabler zip. Connect your device to PC & transfer all the downloaded files.

Step 2. Boot your device  into TWRP Recovery mode. (Jump to step 3 if you’re already in TWRP recovery)

Step 3. Go to Install in recovery mode & Flash  the dm-verity-opt-encrypt zip. (This will also allow you to use [Format Data] to completely disable your encryption if desired)

Step 4. Now flash the SuperSU zip file from Recovery. Wait for the installation to complete & reboot your device.

Keep in mind that the first boot after wiping the phone may take longer than usual, as the phone will need to rebuild the dalvik cache and initialize other first boot and would reboot a few times due to SuperSU Flash. Your phone now has an unlocked bootloader, a custom recovery installed and is rooted.

Conclusion:

That’s it. If you followed every step correctly, your device should be rooted by now and will work flawlessly with an increase in battery life, performance, and power.

  1. did a reboot with ‘fastboot boot twrp.img’ and it just shows ‘1+’ and ‘fastboot mode’ instead of getting into twrp… what can i do to move beyond this screen?

  2. A few important notes that would have saved me a lot of time:

    Your phone directories may not show up on your PC, or may be locked all-together. You have to allow file transfers- It shows up on the phone’s notification screen when you plug in to your PC. I did not know this because I just got the phone and I’m not familiar with it yet.

    Default is an encrypted system. You cant read the .zip files in TWRP in this mode. In fastboot you can type “format userdata” do resolve this, but it deletes the .zip files. They have to be transferred while you’re in TWRP (if there are still issues, see next step).

    My PC could not detect the phone device in TWRP without doing “scan for hardware changes” on my PC. I had to do this to be able to download the .zip files.

  3. The correct comand is FASTBOOT REBOOT and not FASTBOOT BOOT.

    Why?????
    Thats why: Some users need a custom recovery for a temporary period, so they live boot
    the recovery. In this scenario, the custom recovery replaces the stock
    recovery until a reboot is performed. Place the file in your fastboot
    folder then enter this command:

  4. i flash twrp successfully, but then when i tried to boot into recovery it just shows teamwin recovery project and its stuck at that page

    1. dunno if you’ve fixed it but same thing happened to me
      I went back into fastboot and used these commands:
      fastboot format cache
      fastboot format userdata
      before reflashing TWRP. Then it worked

  5. Hello 🙂

    I need some help, how many time is the first boot after do this? I did it, but the OnePlus boot process is taking more than I think.

    My English is not very well, but I hope that you can help me

    Thanks

      1. Did that. Still not booting. 15min and not booted. How do you perform a factory reset by TWRP?

      2. I have the same problem. After flashing SR5-SuperSU-v2.78-SR5-20161130091551 and no-verity-opt-encrypt-5.1, i restarted the phone and it just stays at OS boot screen. I tried to wipe dalvik & cache, didnt help. Still stuck on loading OS.

        Now i want to push a stock rom, but cant find a way to do it via fastboot. And adb doesnt show any devices connected to the computer (fastboot does).

        Any advice?

    1. Welcome. Sorry, i misspoke. I wanted to say that I’m affraid of bricking my phone if I try to root and flash dm verity again with the same method. Is there any possible issues ?

  6. Sourd. I forgot to mention that sincèrement I un grade to Nougat il have a message saint that dm_verity is not in en forcing mode. Phone is working great anyway.

  7. Hello There.
    About 3 week agô I flashed and rooted my phone +dm verity as shown above. I was on android 6 version. I made a mistake by upgrading my phone to Android 7 and non root is gone (which is normal) as well as twrp. So m’y question is : as m’y bootloader is un lock éd alreasy, Can i use the sale method to flash again twrp, root AND install (or decrypt, I dont know) dm verity again ? Seeking not to havé any problems. Many Thanks in advance for your reply

  8. Unlocking bootloader allows installation & changing of System files. You must unlock bootloader before rooting or installing TWRP. You can find the command.bat file in the ADB folder (Click on ADB link & download the ADB zip file from the post).

  9. Sorry if this is obvious but I can´t find the commad.bat file in the ADB folder. Where exactly is it located at?
    But can I skip the “How to unlock OnePlus 3T Bootloader” part? When I press the reboot option om my OP3T I get an option called Bootloader, would that work?

  10. Hi there, I need some help. I installed the driver right from the phone. So, I need the “command.bat”, described at: “Step 2. Connect your device to your PC & launch command.bat file from ADB folder.”

    Thanks in advance.

  11. I am in some desperate need of help as my root may be failed and I am inside TWRP. I flashed both supersu and the anti dm verity file. They both ‘install’ and then I recieve error ‘unable to mount to storage’ – this was not present in the screenshots and so is concerning. I was also prompted with a password when first entering twrp and hit cancel, so not sure if there is an encryption issue causing this error?

    I am too worried to reboot and see if the supersu failed for fear of a boot loop. I am still sitting in twrp and wanting some help from more experienced rooters (this is my first attempt). Should I reflash the recovery ROM, will this stop any trigger of a boot loop? should I just reboot?

    Looking for the best path forward here. Any help REALLY appreciated!! 🙂

    1. Don’t worry. Just reboot & check if everything is fine. If anything goes wrong, you can flash stock firmware from TWRP recovery. OnePlus allows flashing of Stock firmware from TWRP.

      1. Thanks I was not aware that I would still keep twrp access even in a boot loop and could simply reflash. As it turns out I ended up accidentally resetting back to factory settings and then refashing oxygen recovery before testing my root. Will be doing the root again in a few days.Knowing I have twrp and one plus recovery images available makes the whole process fairly safe. Thanks for the feedback.

  12. Hi I am in desperate need of help. I followed this guide to the letter, and flashed both files via the install button in TWRP. They both showed exactly like in the screenshot and displayed ‘..done’. The issue is that directly after that in red letters it says ‘unable to mount storage’. I am scared to reboot after my installs for fear of a boot loop as this was not present in your screenshot…also cant find someone with the same issue after installing supersu ect. Really desperate for some help.

    Many thanks.

  13. hi newbie here
    i wanna ask, is it possible to flash stock rom without twrp? i have the chinese version and hydrogenOS is not my thing, so i want to flash it to oxygenos. is there any other way to flash stock rom? like odin maybe?

    and is it possible to unlock bootloader and install twrp but without rooting it? so just stop until install TWRP without swiping right to allow modifcation

    sorry for bad english and trivial question
    thanks in advance

  14. Correction to TWRP installation Step 2:

    If you have downloaded the TWRP Recovery file, transferred it into Minimal ADB Folder and renamed the TWRP file to TWRP.img then you should:

    Open a command window and type:

    fastboot flash recovery TWRP.img
    and not
    fastboot flash recovery recovery.img
