Data partition failure after flashing custom rom - P8lite Q&A, Help & Troubleshooting

Hello! Good morning, I managed to unlock the bootloader of my phone and installed the recovery, at the beginning I managed to test as 3 different roms (all signal failed me) and when I went to test a 4th rom in the process of flashing it gave me an error "failed to mount / data (invalid argument) "and from there made a bootloop, searched the internet and said to change the partition to ext4 and then return it to as it was before, but without success, it followed the same data problem. As a precaution I had made a copy of the complete system with TWRP and I proceeded to restore it, but in the process my gave the same error and when I went to restart it did bootloop again and when I went back to the recovery there was the system and from there I made a complete formatting of the phone and with luck I manage to start. Then I reinstalled TWRP successfully, but for example trying to make a backup gave an error in the data, and in TWRP it is not possible to mount the data even manually. At the moment I use the phone with EMUI 4.1, but someone knows how to solve this problem or it has happened to someone. I appreciate your responses and attached a screenshot from TWPR.

[Q] Nexus 7 bricked & unable to flash

Hi everyone, first I have to say that English is not my primary language so I apologize for any inconvenience.
So what stupid things I did was, I used Nexus Toolkit to upgrade to 4.4 Kitkat from a Custom ROM and Custom Kernel
After I realized it, i wasn't able to boot up the device properly
neither the Android itself nor the Recovery
All of it will show up a line of word "Booting Failed" on the top the bootloader screen
I tried to recover it to stock using Nexus Toolkit but sadly it started to fail after those erasing command
(Even using the flash-all.bat)
Now the device is still can be found by using fastboot devices
And I tried to flash CWM and gives out the error output :
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
What can I do now ?
Helps is much appreciated
SOLVED
After booting to temporary recovery, I found that the only problem is that the internal storage is unable to mount
So after wiping every thing and format I managed to flash recovery and system too now

N910C Bootloop and corrupt /data/ after trying to return from CM13 to Stock.

Hello,
I updated to Bliss Rom a while ago, didn't liked it and tried to return to Stock 5.1.1, but didn't worked. Well, I decided to go for the CM13 rom which where much better. However I saw the Thread here where someone explains how to get back to Stock from CM13 and I tried it, Step by Step everything went successful, except that nothing works now...
The EFS Clear part went fine, I saw some having trouble with it, so that can't be my problem, hopefully.
I use to recover these firmware/bootloader: COJ5 and tried it with COH4, not working.
I made a backup of my CM13, but if I restore it, it fails...fking hopeless :/
I hope someone can help me.
Here Screenshot of my Odin I started after clearing my EFS with EFS Pro.:

Do an efs format through twrp as i explained in the guide threads. After flashing the stock rom make sure to boot in stock recovery and factory reset.

Decrypt data option
I was checking the "decrypt data" option inside the mount storage section of TWRP and once I checked it, this solved my problem. Now internal storage seems to be working fine.
Thanks.
That shows like that when your data is encrypted. Glad you got it working.
Wow!! I logged in to ask about the exact same problem. Even have a screenshot of the encrypted files. No need now. Your solution worked perfectly. Thanks!!
Hi I have flashed the latest OTA now all my files are encrypted when I select the SD card from TWRP.
How did you fix it exactly can you post a screen?

need help installing custom rom

im trying to install a custom rom on my mi 9t. its not the first time that ive done this, but now its all gone wrong. I have unlocked the device, flashed twrp, and got the rom/gapps ready to go, but when i go to install it i get 2 errors, "E:unhandled flag: wrappedkey" and "E:unable to decrypt fbe device". and just to make things worse, i came to the brilliant conclusion that the errors were from the old rom interferring with the new one that i was trying to install, so i deleted the system partition and wiped my os.
feel free to call me as many names as you like, so long as you also provide some help aswell haha.
thanks guys

If you have twrp I stalled, then you just need to factory reset in recovery, format partition, flash dmverity, flash ROM and optionally root. There is nothing you could do wrong if you choose proper ROM for your device - each ROM has instruction what you need for it to work properly

How to recover from factory reset on TWRP

Hi
I had an open stock firmware on my LG G6. Unfortunetly I made factory reset as the phone was crashing apps.
Now the phone will boot into TWRP but flashing any of the firmwares is a failure.
First it was unable to unmount /system so i switched it to ext3 and back to ext4. Now the flash ends with result 1.0000 and after reboot im still in TWRP.
I can enter TWRP or start recovery with Vol Up, however in recovery it says with red MODIFIED / E / L / R0 / id :0 ()
I tried using LG UP but im stuck on this and none of the dll's seem to work for me.

}
How to proceed to unbrick it ?
None of the dll's worked for me. I've let this rest for a few days and then stupidly found solution when searching for an answer, some info that installing LG Bridge might solve the dll issue.
It appeared that there is a magic button which recovers all phone with one click on Recovery within LG Bridge software.
Just a question. Is it now safe to lock the boot loader so I can run android pay?
