[Tool][Unbrick][Reset][Fix for bad Signal] Stock Firmware

[sm00th4f3]

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

Thanks a lot. You literally saved my life!

 

[krishnakoonala]

Works like Magic

Thanks a lot for saving my ass . simplest way to downgrade to mm too. Thanks again

 

[eried1]

Wait.... downgrade to MM? Does this mean you can regain your signal or did @krishnakoonala get it wrong?

I have a spare P2 lying around that I never used because the IMEI got corrupted and I couldn't flash the bootloader files since I was unlocked.

I assume this wouldn't solve my issue?

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

[GuestK00412]

@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.

So how does it fixes corrupted modems? it cannot be flashed on unlocked P2 right?

I literally just answered it above somewhere.
(Literally in thread description)

You can flash it on unlocked bootloader or locked as well.

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
