My phone is stuck at boot password - Lenovo P2 Questions & Answers

Hi guys,
I have put a pattern for booting to unlock the phone. I have restarted the phone multiple times and entered the boot pattern without any issue.
I have flashed a MIUI8 ROM and about 3 days later I restarted the phone and my phone is now asking for a password to boot.
Even when using TWRP it is asking for the password to decrypt the mount data.
Can anyone help me? Im open to deleting the phone.
Is there a way to formate the entire phone while booting?

Help!! S4 Mini stuck on bootloop during encryption with Green Wired Android

Hello folks,
I tried encrypting my Samsung Galaxy S4 Mini GT-i9192 (it's required for me to get my work Exchange email natively). It asked me to set a PIN which I did and then required me to press the Encryption Button.
I did that and the phone rebooted immediately. Since then, it goes to the Samsung Logo and then screen to enter the pin comes.
When I enter my PIN, screen goes black and after 10 seconds phone reboots. And this loop continues again and again.
I tried factory-reset my phone still not able to get into the phone. I also tried flashing the stock image using ODIN. Also tried NAND Restore.
My phone is rooted and CWM installed.
Please help. I am not able to do anything.

Pattern unlock not working

Strange issue. So I decided to flash AICP and gave it a shot, but for some reason the setup did not go past the 'set fingerprint' screen. So I decided to head back to my OOS nandroid backup. But after boot I was not able to unlock the screen with the same pattern that I used to unlock both TWRP and the encryption of the device. What could be wrong?
It's a twrp bug. Before u make a nanodroid backup remember to remove your lockscreen password
I setup pattern-unlock yesterday and used it a few times. Now that same pattern isn't working. I can boot into TWRP and that pattern will work. So I factory reset and the pattern lock is still there and I am still unable to get into my phone. How can I fix this?
Edit: I forgot to mention that I am getting an error "unable to mount storage".

Wrong encryption pattern after flash

Hi,
Today I tried to flash a new version of Lineage OS on my phone, while the encryption pattern on boot was stil enabled. I didn't realise this would cause such a problem..
Right after flashing Lineage OS the way it should, a message pops on the screen asking me to enter my pattern to start the device while booting, so I entered my code after which it says my code is wrong. The strange thing is that TWRP also asks for that code on startup, except now code is working.
So I can boot in recovery mode and decrypt the device with my old code, but as soon as I try to start the rom (tried LineageOS, my Nandroid backup and AOSPA) the same code doesn't seem to work.
I've already tried this method: https://forum.xda-developers.com/nexus-6p/general/psa-twrp-backups-lockscreen-security-t3245070, but this resulted in a bootloop.
Any idea how I can get rid of this problem and start using my phone again?
Thanks alot in advance!
Fixed it by using the 'Format Data' function in the wipe screen of TWRP! :good::good:

[SOLVED] Bootloop after flashing IMEI qcn file, caught in vicious circle

/EDIT:
Alright, the thread can be closed. I somehow managed it.
In case someone faces the same issue, I used twrp to dd the sdf files back on the phone which stopped the reboots. After that, just wiped and formatted everything again and reinstalled the ROM.
Hello guys,
I hope you can help me with this issue since I've tried everything I know to fix this problem.
The plan:
Unlocking bootloader, installing TWRP and xiaomi.eu ROM on a new device.
Changing its IMEI with QPTS/QFIL afterwards.
What happened:
Unlocked successfully. Installed TWRP, xiaomi.eu ROM and Magisk.
After pulling the QCN backup and editing the file I pushed it back to the phone what seemed to work.
After rebooting, I noticed that the phone rebooted 5 seconds after showing me the "Enter PIN" screen.
Booted up again and the same thing happened.
I booted into TWRP, wiped and formatted "data", installed the ROM again. The phone started up normally and there was no reboot.
I went back to TWRP and flashed Magisk, the phone crashed again and everytime I boot it up, it immediately reboots after some seconds. Installing Magisk somehow triggers the phone to reboot on its own.
I thought to start over, flashed everything from stock using Mi Flash Tool and the newest China Rom.
After starting up the phone, the issue still exists. This time with this rom there is no difference between installing Magisk or not, the phone always reboots after showing up the miui welcome/setup screen.
Current situation:
The phone boots up Android, reboots after some seconds and goes into fastboot automatically. After the fastboot timeout it again reboots automatically, goes into the OS and crashes again and on and on.
No matter what I do, I can't keep the phone from rebooting.
And since I can't flash Magisk, I have no root.
This means that I can not use root to put the phone into diag mode to restore the original qcn file.
I have backups of the EFS partition and also sdf7/8/9/10 files. I just don't know how to restore them given the current situation.
Thank you very much in advance for your support!
Cheers
