Lenovo P2 encryption failed - Lenovo P2 Questions & Answers

Hello
So this evening I tried to flash the Android Pie version of Liquid Remix.
Flashed ROM and Gapps without any problem.
Then after I typed my pin to load the OS, i got an error saying "decryption failed"
So, i tried to follow the instructions on screen, it rebooted to twrp and then to the system and i got the same result.
Then I did a full wipe of my partitions (System, data, dalvik, Storage and cache) and reinstalled the rom and the gapps.
This time I got the error "encryption failed".
So i booted to recovery, but now it's like i'm locked outside. I'm not asked for Pin to decrypt and I can't do anything.
ADB says decive unauthorized. AM I DOOMED or there is a solution?
UPDATE 1: I'm not and android expert, and i don't know what is happening to my phone: So I desperately rebooted into system from twrp, and it actually booted into the os. There wasn't any "first launch" procedure but i'm in.
Did the phone fix itself or AM I still DOOMED?

[Q] Soft-Bricked phone, would like to restore to Stock OS

I was having some problems connecting to my mobile network, I couldn't access Google Play Store, I couldn't read Chinese well enough to figure out how to download and install new apps from China's playstore, so I decided to flash a custom OS on my P6 to play around with.
These are the steps I've taken and where it's led me to now -
Installed TWRP on my phone
Installed ADB and Fastboot onto my computer
Turned on Developer Mode and enabled USB debugging
Copied new OS Zip into my memory card
Restarted phone into TWRP recovery
Followed instructions to wipe dalvik, cache, data, and system (I'll try to find the link after this post)
Attempted to install the new OS (Failed due to incompatibility, stupid me)
Tried Sideloading an official Huawei released OS from their website (Failed to recognize my device on adb)
Tried Rebooting my device into Bootloader and attempted to load a Zip to force update my phone (and displayed "e:failed to mount /cache")
Flipped through xda and thought I needed Stock Recovery to load an official OS, so I fastboot flashed it in
Rebooted my phone into Recovery, saw "wipe data/factory reset", so I attempted that (displayed "E:failed to mount /data (invalid argument)
So... I'm stuck here, not sure what to do next because I think I'm just breaking my phone more than I'm trying to make it work... Can anyone help me out here? ._."

By the steps you've taken i can tell you are on stock recovery at this moment and with no system installed on phone, so i would suggest you downloading an official stock rom (update.app file) and put it in dload folder in a SD card and try to install. Now one thing that you should be aware before attempting this is to make sure you have the same version of OS as the one before, either JB or KK. Good luck.

Soft bricked Find 7a

Hello there, hope someone can help me with my problem.
I softbricked my Find 7a while trying to reinstall ColorOS 2.1.5 stable. When I boot the phone up normally, it tells me that "SystemUI has stopped working" and that the Encryption was unsuccesful. no problem, I thought, lets just wipe everything and reinstall it via ColorOS Recovery.
But nothing works there - I can't wipe data, it always tells me I need 250 MB free space - and just reinstalling ColorOS 2.1.5 didn't help - it says the installation was succesful, but when I boot it up, its again "Encryption unsuccesful", just like before. Trying to wipe everything via fastboot didn't help either, (used 'fastboot erase xxx', whereas xxx stands for cache, system, userdate, recovery and so on), I always get the following message: FAILED: (remote: failed to erase partition)
I've also tried the unbrick tool from Irwenzhao but whenever I click on start a green bar is loading but after 5 seconds my phone just reboots, no matter how often I try.
I also have the feeling this has something to do with a failed unification (LVM), because I tried to switch back so it would maybe work... nothing.
Seems like I cant delete anything, even though I can boot up the phone, go into fastboot mode and go into recovery mode (which was useless so far since nothing works here)
Am I missing something here? Would be great If someone could help me out here..
Do you have LVM installed before per script? Try uninstalling it (Although ColorOS should work with LVM): http://community.oppo.com/en/forum.php?mod=viewthread&tid=46285

[HELP] unmount of /data failed (-1) device or resource busy

Hi, I've got a huge issue with my phone.
I was using the PureFusion 8.0 EAS Rom and i wanted to get back to stock because of some bugs in this ROM (audio issues with my headphones, low battery life ...).
I've tried to use the RUU.exe but I got an "Error 170 USB Connection". So I searched for a stock ROM with oreo and I decided to download LeeDroid 8.0 and another Deoxed stock ROM.
I've done A wipe cache & dalvik and install the LeeDroid one, choosing data encryption. But it doesn't ask me for a password and the phone encrypt itself after that, the phone bootlooped and I've been waiting for about 15 minutes to see if this was really a bootloop or just a bad boot animation. Then I restarted the phone to install the Deoxed's Rom but I can't, their is an error message with "unmount of /data failed (-1) device or resource busy" and when I boot up the phone it's stuck on HTC build for developpement purpose only (...).
How can I make the ressources no busy again ? Is it because of the encryption ? I've tried full wipe (data, boot, cache, system) but for the leedroid or the deoxed's rom I get stuck on the HTC's logo.
