So I've installed both and the latest The popup to allow for system modifications never show. I cannot permanently install TWRP.

Does anyone have a solution?

For the time being I reverted to Maybe TWRP will stick if I updated through TWRP using this version?

Edit: So it seems this procedure worked.

    Team Win Recovery Project 3.2.2-0

    This is for the Lenovo P2a42 only! Do not flash on the Lenovo P2c72!

    WARNING: Rooting The Lenovo P2 with SuperSu currently works only in System-Mode, which prevents you from installing OTA Updates!
    INFO: Follow the full rooting steps below, in order, to allow system modifications!


    Oh come on, you know what it is - don't try to fool me!
    In case you're serious, though...

    Team Win Recovery Project is a custom recovery for Android devices.
    It allows you to back up and restore your data, flash custom ROMs to your device, repair broken file systems, and root your device.

    Read more about TWRP here: https://twrp.me/about/


    You can find the Official Download here (Version: 3.2.2-0): recommended!

    You can find the Pre-Official Download here:Currently no Pre-Official!
    See Post #3

    This is the download link, for instructions on how to flash it, see below.

    You can find up to date fastboot & adb binaries here!


    Follow these instructions until someone nice comes along and makes a video from them (without ads):

    1. Extract/ install adb & fastboot to your computer.
    2. Download TWRP for Lenovo P2 (P2a42).
    3. In your ROM, go to Settings -> About device. Tap 8 times on Build number to enable Developer options.
    4. Now go to Settings -> Developer options. (above About device)
      You need to enable OEM unlock, otherwise you might end up with boot problems or be unable to flash later on.

      Once you tap the unlock the bootloader it will ask you to formally submit the request, when you accepted the void warranty thing you will have to wait 14 days.
    5. After 14 days :eek: . Reboot your device into fastboot mode. To do this, (adb reboot-bootloader) or select reboot from the power menu and hold the [Volume Down] + [Power] buttons while your device reboots or boots from power off.
    6. Once you're in fastboot mode, you need to unlock your bootloader. To do this, run this command:
      fastboot oem unlock
      WARNING: Unlocking your bootloader will erase all userdata on the device! Your device will be completely reset to factory defaults!
    7. Once your bootloader is unlocked, you're ready to flash TWRP. To do this, run these commands in order:
      fastboot flash recovery twrp.img
      fastboot boot twrp.img

    8. At this point, you will reach the screen asking you if you want to allow system modifications.
      By swiping right, you will trigger system modifications for TWRP and TWRP will be installed permanently!
      If you are going to root your device and follow the rest of these steps, then it is safe to swipe right and enable modifications.
    9. If your device asks for a password to mount internal storage, and your password doesn't work or you haven't set one, see below under known issues for a fix!

    10. If you want to be rooted see Post #2:


      To update TWRP, simply download the new twrp.img on your phone, then boot into your current TWRP and flash it.
      To flash a twrp.img, navigate to [Install] -> [Flash Image] -> select your twrp.img -> [x] Recovery -> Flash!
      After that, just use [Reboot] -> [Recovery] to reboot into the updated TWRP.

      • SuperSU will only work by default in System-Mode because the data partition is F2FS! (by default from Lenovo)
      • SuperSu's Systemless Mode will work when the data partition is changed to EXT4!


      If your device isn't decrypting in TWRP, chances are you set a boot up password.
      You can solve this by disabling your boot up password in your device OS's settings.
      By disabling your password your OS will rewrite your crypto key to be compatible with TWRP and TWRP will decrypt with the default password.


      When TWRP boots up or wipes partitions and a few other scenarios, it checks each partition to see how much disk space is used. Ext4 handles disk usage calls quite efficiently and will finish this very fast. F2FS on the other hand is very slow when it comes to checking disk usage. We're unsure why this is. Every file on the F2FS formatted partition adds a little more time, and a device that is 30 GB full could take up to 10 minutes to boot TWRP!
      I suggest switching your data partition to ext4 - all the f2fs hype is merely from benchmarks that don't actually represent real world use (ie. you're not writing thousands of files per second)
      For someone who doesn't do lots of write access to their data partition, ext4 can actually be advantageous (it has faster access times and reads!)

      Official TWRP vs LineageOS TWRP
      I am on Lenovo's STOCK ROM! All i want is root with STOCK ROM! I don't care about treble! Is this version for me?

      I hate the Lenovo STOCK ROM! I want LineageOS Official and root! I want treble and Magisk! Is this TWRP version for me?!
      NO!!! Why? Please read this!
    Confirmed and working ROOT methods!

    Up-to-date: For root with Nougat please use phh's supersu
    Use version 2.59 from here
    Install phh's SuperUser in the Play Store
    to manage root access of apps.
    Simply flash it and enjoy.
    If you prefer Magisk:
    Prio to installing Magisk you will have to change the data partition from F2FS to EXT4 because the Lenovo Kernel is missing an F2F2 feature.

    How to format data to EXT4:
    Make sure while the first time you boot TWRP.
    You "KEEP SYSTEM in READ ONLY MODE" by clicking "Keep Read Only"
    then Go to:
    Wipe>Advanced Wipe>Select "Data">Repair or Change File System>Change File System>EXT4

    Install Magisk
    and once you booted up the system install Magisk manager.

    Proof that Magisk works see attachment!

    Outdated Root Method for Marshmallow ONLY:

    Here is for confirmed and working ROOT METHODS !!! Marshmallow ONLY !!!

    download this pack https://goo.gl/KFtyzl
    and extract its content into the adb&minimal fasboot folder
    enter TWRP
    adb push dot.supersu /data/.supersu
    Select "ADB Sideload" in TWRP menu, (Advanced>ADB Sideload) make sure to select "Wipe Cache" and
    Swipe to to Start Sideload and use following command to push SuperSu files.
    adb sideload SuperSU.zip

    Reboot into System. Done!

    FOR SYSTEMLESS MODE ROOT ONLY: (preferred method!) !!! Marshmallow ONLY !!!

    As i stated in the Opening Thread. SuperSu can not be installed in Systemless-Mode by default because by default the /data partition is formated in F2FS.
    More detailed explanation here: here

    The current workaround is to disable the encryption (fully optional) and wipe the /data partition and format the /data partition to EXT4, which is also supported by the boot.img (thank you Lenovo!) and install SuperSu in Systemless-Mode. EXT4 formatting can be done through the "advanced wipe" of TWRP.

    It has been tested and confirmed working. The main advantage is working OTA due to systemless SuperSu. As the OTA doesn't care if /data is actually F2FS or EXT4. Lenovo was so kind to provide both options in the stock boot.img.

    Q: I messed up help me?! :crying:
    So you screwed up and didn't follow Rule Number One in the IT-Handbook?
    Which is: Always create a backup before working on a system?

    (FACTORY IMAGES FOR Marshmallow ONLY!)

    Warning! Following images are all confirmed working for the P2a42!
    Do NOT attempt to use it on the P2c72 it will brick your device!
    If you need an P2c72 factory flasher version! Let me know i will provide you with one!

    Download the Factory State Images for Marshmallow. Which are all flashable with fastboot: https://goo.gl/JTCwKj

    Place the files you want replaced into the "Minimal ADB & Fastboot" installation directory and start it's shell:
    If you want to flash back the stock recovery. Simply run:
    fastboot flash recovery recovery.img

    You can also replace all partitions if required.
    There is an flashall.bat file in the SW directory. Run it in case you want to restore all partitions.
    But i highly recommend to replace just the partition you messed up. In most cases it will be boot,recovery or system.

    One exception would be if you want to upgrade from an Old Firmware and you simply do not receive any OTA update files.
    In that case you want to run a complete upgrade by running the flashall.bat file.

    Pre-Official TWRP Images:

    TWRP 3.2.2-0 (latest version)
    Currently no Pre-Official.

    Q: Why Pre-Official?
    A: It's is an "canary build" meaning, in test phase before it gets pushed Official but it is fully tested on Marshmallow and Nougat. Even confirmed working for the P2c72.

    This is what happens if you are married to the best wife in the world!

    She buys you a Lenovo P2 as a wedding present!

    I will now proceed with bootloader unlocking and look into any issues that TWRP might have left on the P2.
    For those that did not know. I did NOT own a P2 before creating TWRP for the P2.
    However I do now! Which makes things easier.

    Big thanks for all beta testers! And a very big thanks to my wife!
    I will no longer keep reading the thread and therefore no longer reply to any questions.

    It's simply a waste of time. I prefer spending the time to actually help mike in the development of the Official LOS.

    I will keep updating the Official TWRP for the Lenovo P2. No worry's there.

    For any other questions relating to "rooting" or "how to's".

    1. Use common logic!
