I AM VERY HAPPY TO PRESENT A SOLUTION FOR ALL THOSE WHO LOST VOLTE AFTER INSTALLING LINEAGE OS OR HAVE LOST EFS...:fingers-crossed:
Things you will need :
1. STOCK ROM BY @rajatgupta1998

2. LINEAGE OS BY @rahulsnair ( TO RESTORE THE EFS )

3. PERSIST FILE BY @akshu2697 (original solution by him)
Link: https://forum.xda-developers.com/attachment.php?attachmentid=4467052&d=1522904127
STEPS TO GET 4G VOLTE BACK :
1. Install the Lineage OS as mentioned by rahul and then make a backup of the EFS in TWRP.
2. Install stock rom ( written above )
3. Install TWRP again on it.
4. Extract the persist file and copy it to your lineage EFS backup folder.So now the file in your backup folder should be EFS and persist.
5. Place the BACKUP folder in your TWRP.
6. Start TWRP in your Z2 play restore the EFS first and then restore the Persist file BOTH ONE BY ONE.
NOW REBOOT YOUR Z2 PLAY AND ENJOY VOLTE AGAIN .

Sorry to bring back this thread from the dead : does anyone still got those files? My friend Z2 is stuck with IMEI 0 and at this point, it's worth a try

Thanks! I'll give it a try later today
EDIT : done, IMEI is still at 0, but VoLTE work again, wooooo \o/

Hey Guys,
After following all the steps properly with caution i was able to make the stock rom in a CWM recoverable file
I AM NOT RESPONSIBLE FOR ANY DAMAGES MADE TO YOUR DEVICE IF YOU MAKE A MISTAKE IN BETWEEN
BUT I WILL ASSURE YOU THAT I WILL TRY MY BEST TO HELP YOU
This are the files that were backed up , just check to be sure you have all files in the folder / zip
~ System . ext4 . tar
~ Recovery . img
~ uboot . img
~ Boot . img
~ nandroid.md5
TUTORIAL
Step 1 : Unlock Bootloader to flash CWM / TWRP recovery
GUIDE : UNLOCK BOOTLOADER
RECOVERY : DOWNLOAD
I DID NOT MAKE THE FILES TO UNLOCK BOOTLOADER : EVERYTHING WAS DONE BY :
SALMAN986 AND PRIYANSH21
I recommend using cwm
STEP 2 : Extract the stock rom to CLOKWORKMOD/PHILZ/TWRP in sdcard/sdcard1
IF YOU CANT FIND THIS FOLDER > YOU CAN BACKUP YOUR ROM AND CANCEL IN BETWEEN SO THE FOLDER IS CREATED AUTOMATICALLY
STEP 3 : select restore or advance restore
VOILA - The stock rom will be restored
WITH ROOT (KINGROOT) AND BUSYBOX
IF YOUR DATA IS NOT INTACT / PHONE DOESNT REBOOT , CLEAR DATA & CACHE FROM RECOVERY
BE SURE TO LIKE MY WORK , AND HIT THE THANKS BUTTON
MAIN CONTRIBUTORS:
SALMAN986
PRIYANSH21
PLEASE LIKE THEIR WORK TOOO , WITHOUT THEM WE COULD NOT HAVE THE TAIWAN STOCK ROM FOR OUR DEVICE
DOWNLOAD STOCK ROM HERE:
MEGA
Hey, you can do as follows:
~~~~~~~~~~~~~~~~~~~~~~~
Requirements:
* PC
* CWM/TWRP Backup
* CWM/TWRP Installed
* Winrar/7Zip
* Brain
Now the real-deal..
1. Copy the backup from Phone to PC
2. Extract system.ext4.tar file with winrar/7zip, you
will get the system folder
3. Collect the boot.img from the backup
4. Now collect a META-INF folder from any custom
rom/small update zip which is made for HTC Desire 526G+
5. Now select META-INF,system & boot.img, click
right button of your mouse and select 'Add to archive'
now select archive format 'ZIP' and press ok
6. Your flasable zip rom is ready. Just copy it
to your sd card and flash with CWM or TWRP
7. Done!! This will flash the stock Taiwan System to your device.
Make sure to hit the thanks button!!
P.S. Can you give the link for Indian Stock ROM.
Thanks.. i followed the procedure suggested by you. Really it is working. Is there any possibility to edit the source code and (As per my customization) compile, generating the images and flashing back. If yes which cross compile tool is required and how to get source code.
Philz touch recovery download for STEP 1 , Instead of using CWM / TWRP

Yes, you should backup also modem into TWRP, in this way fingerprint will work wen you want to return to stock. So, make a full backup before flash CM-13.0.... if you want to return to stock just restore backup.
Good luck !

The link provided for B140 is not from Huawei site, so you will be able to download ( is already a mirror link ) !
cust.img - 114.78 MB
Installations steps :
- install TWRP 3.0.1-0 !
- go to TWRP and perform a backup ( including : System, Boot, Data & Custom ) !
- root your device using TWRP ( you should flash : UPDATE-SuperSU-v2.46.zip )
- reboot your device and connect USB cable :
> adb shell
$ su
# dd if=/dev/block/bootdevice/by-name/cust of=/data/local/tmp/cust_orig.img
# chmod 0644 data/local/tmp/cust_orig.img
# exit
$ exit
> adb pull data/local/tmp/cust_orig.img
This cust_orig.img is your backup of your custom partition !
Now just download my cust.img and also B140 Firmware from the link above . Extract UPDATE.APP from B140 and put it on your external card ( MicroSD ) into dload directory : you should have : MicroSD/dload/UPDATE.APP !
Flash my custom partition on your device :
> adb push cust.img data/local/tmp/
> adb shell
$ su
# dd if=/data/local/tmp/cust.img of=/dev/block/bootdevice/by-name/cust
# reboot recovery
Device will bot into TWRP ... here just go to : Wipe -> Advanced Wipe , check : Dalvik/ART Cache, System, Cache & Data -> Swipe to Wipe !
Just got to Reboot -> Power Off .... disconnect the USB cable ... than : while you keep pressed at the same time : volume up & volume down buttons , just keep pressed also power button ... device will start soon to install UPDATE.APP !
That is all ... now you should check update , and install OTA B180 before to flash UPDATE.APP from Huawei MM B340 !

It was just a suggestion the stuff with flash cust image from B140 ... now, if B340/330 it not working , you should restore your backup and your device will function without issues !

Hello guys,
I have a lot of problems with my cust partition and as moving the files from the cust partition to another phone works, I need the files of the cust partition from someone on any global MIUI 9 based on android 8.1.0 (REDMI NOTE 5 PRO / 5 GLOBAL)
Please upload it to something and share it
It will save my device and fix the problems
Guide:
1. Boot to twrp
2. go to the file explorer of twrp
3. go to the root of the device
4. go to the cust folder and copy everything from there to your internal storage and move it to your PC via MTP
5. add the files to a zip file and upload it
Thanks and have a good day!

I need this for another phone, so unfortunately I cant do that
I have been using this Mi 11x (Indian variant of Poco F3/ Redmi K40). It has TWRP by Nebrassy as latest version of Magisk (v23) installed and working. Magisk is working in systemless mode. System structure shows partitions Slot A and Slot B in TWRP. Whenever I attempt to delete any system file using root privileged file manager it return 'failed to delete : error code 1'.
I did try deleting these files using TWRP file manager. There also it says 'failed, Code 1'.
What am I doing wrong. And how to correct it? Please help...

I worked on my mi 11x with unlocked, magisk rooted Xiaomi.eu 12.5.4.0 rom (android 11). I just downloaded the flashable zip file from the site attached) and installed it in TWRP recovery. Pretty straight forward... But u need to have atleast 20gb internal memory free, where a backup of your super.img will be stored (u can delete this later). My advice is to go through the thread once since I have read certain feedbacks where the device went into bootloop.

Be sure to mount System, Vendor, Product atleast before starting the installation process in TWRP
