I decided to root my phone in order to try some roms but OEM unlocking is not working. I did it 5 days ago but today I got "Lenovo ID not authorized". Can somebody help me please?
You need to wait 2 weeks for the bootloader to unlock, you can check how much time is left when you click on unlocking again.
When I do that it says "Lenovo ID not authorized". That's why I asked in the first place
version 3.4.0

No, I used it with Lineage 17.1 official (by Mike) and it's working fine. I don't know about android 11 ROMs because I didn't tested it yet.
PS: Just for the record, I'm not the developer of the recovery, I'm just sharing it here.
Hello, i note in this version 4.4 crash with "lenovo part" in sytem, also android auto don't work. the version 4.2 all works perfectly.
What worked for me in past is yukle.exe flashing after twrp backup --- precisely yukle.exe S048 flashing + [Stock Rom] [Lenovo P2] [NOUGAT 7.0] [Deodexed_P2a42_S244_170725_ROW]b4 return to previous rom....but now don't have these files due hdd crash else will share & if i am requesting then it's been removed by xda....so if you have try these & will resolve your problem

51Team 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!
WHAT IS TWRP?
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/
DOWNLOAD
You can find the Official Download here (Version: 3.2.2-0): recommended!
https://goo.gl/UbHbkr
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!
FULL STEPS FOR OBTAINING ROOT
Follow these instructions until someone nice comes along and makes a video from them (without ads):
- Extract/ install adb & fastboot to your computer.
- Download TWRP for Lenovo P2 (P2a42).
- In your ROM, go to Settings -> About device. Tap 8 times on Build number to enable Developer options.
- 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.
- After 14 days
. 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.
- 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!
- 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
- 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.
- 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!
- If you want to be rooted see Post #2:
UPDATING TWRP
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.

DECRYPTION NOT WORKING?
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.
WHY DOES F2FS MAKE TWRP SO SLOW?
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?
YES!!!
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!
20Confirmed 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!

13This 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!9I 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".
Simply follow this guidelines:
1. Use common logic!
2. Read the main three posts!
3. If you don't like reading, watch the provided YouTube videos!
4. Help each other out! < XDA is a community!
5. See Rule No.1 - Extract/ install adb & fastboot to your computer.
