Using this tool i can go to MM version and can upgrade to S251. However after installing twrp and flashing custom rom, it goes to bootloader

Make sure you do the following steps coming from Stock Rom:
change the file system of data partition to ext4. then reboot while being in recovery to recovery. (Use the Reboot->Recovery Option you can find there)
Doing this will also wipe internal storage, so make sure you backup your stuff.
Then you wipe ONLY system,cache,dalvik_cache.
Flash Custom Rom, Gapps and if you want root either Magisk/SuperSu.
Wipe dalvik and cache. Reboot.
First boot may take up to 5mins at most.

Also when changing custom roms make sure to never wipe vendor, because you might lose mobile data while doing so.

EXTRA: A so called Clean Flash is referring to the following partitions being wiped.
- System Partition (AND NOT SystemImage!! Never touch that)
- Dalvik Cache
- Cache
- Data (Excluding Internal Storage)

I flashed this as per instructions.
Admittedly I am trying anything including this to get my real IMEI's back as I flashed/erased too much at the beginning.
The IMEI's from another person's TWRP recovery were ther, but after flashing this, the IMEI's have gone again.
Also, the very first OTA update sticks at 24% and then says update failed.

My p2 was bricked and , stuck in boot loop. I followed the above instructions, 10 mins into it , it booted with mm version, the same version when i bought and booted for 1st time. It was like a new phone to me.

So i assume if one has upgraded to noughat and want to downgrade but is worried he might brick his device, one can take a back up and try this tool. It works flawless.

No harm in trying this one if ur p2 can boot up mate. Give it a shot. Good luck

Cheers :)

Bootlooped means only light appeared for u?

    Unbrick tool by One-Team - EypCnn

    First: This tool seems to be from EypCnn, One-Team. All credits to them!

    EDIT2: I no longer own this device, so i will leave this thread here for people to use. But don't expect any direct support from me :) .

    What can this tool do?:
    • Restore phone to Stock(International) Firmware (S048) Marshmallow (Locked & Unlocked bootloader)
    • Fix Lost or bad Signal / IMEI any software Problem

    For who does this work?
    • Pretty much any Lenovo P2 Variant (Chinese and International)
    • Phones which can access bootloader(you have to boot into it)
    • Works on Locked & Unlocked Bootloader

    Installation aka. Flashing-Steps

    Put your phone into bootloader (which is also fastboot) mode.
    Download the folder and unzip it.
    Connect your phone to your pc.
    Go into the unzipped folder and open "flashall - stock reco.bat"
    Wait, for the process to end, your phone will reboot on its own.! A stock lenovo bootlogo will show up ;)!
    You can disconnect your phone cable from pc and plug into a wall charger, just to be safe. Once the lockscreen is showing up, you're done.

    If you want to flash Custom Roms:
    look below:
    WHEN MOVING TO CUSTOM ROMS NOW:

    1. Boot to twrp. (Make sure it is pietwrp from telegram or the official 3.2.3 or later version)
    2. Select WIPE menu option
    3. Select data partition
    4. Change file format to f2fs or anyother.
    5. Go back to Start Menu of TWRP, choose Reboot Menu Option
    6.Reboot to Recovery
    7. Repeat Steps 2 and 3
    8. This time select EXT4 when changing file format
    9. Do Step 5 and 6
    10. Wipe System,Cache and Dalvik-Cache partitions
    ( for older twrp versions: 10.1 If you're on official twrp 3.2.3 or lower, you have to flash pietwrp or latest twrp now !)
    11. Flash your Custom Rom, Gapps (optional) and latest Magisk(optional)
    12. Wipe Cache and Dalvik-Cache
    13. Reboot. First Boot might take a few minutes but never longer than 7minutes.
    If it takes longer, you're encounter a so called bootloop.
    Comment hear if that happens, containing information on your twrp-version, rom, gapps, magisk and mods(if present) you're using.

    When you corrupt your internal Storage or geht TWRP Error 1001, Error 7:
    1. Repeat steps 2-6
    2. Repeat steps 7-8

    2nd Link(reuploaded because some couldn't download it from androidfilehost): https://drive.google.com/open?id=1wUOZiTwW8mo0IheAGONyj9-QnjimnY2M

    I will help if questions arise.

    This tool has saved my device from multiple over a span of two years soft bricks. Can confirm it to do wonders.

    @sm00th4f3 bro, i wanna know, does this tool flashes full ROM including modem files etc, even on unlocked bootloader?
    What is the state of bootloader after using this tool?

    It flashed everything you have when you buy a new phone. And no, it doesn't lock your bootloader.
    So you can either :
    - keep using MM Stock Rom S048
    - Update via ota in System like you normally would do.
    - Update till latest Firmware, then flash twrp- and then Custom Rom of your Choice.

    Bootloader is in the same state it was before you used this tool.
