Seeing lot of users struggling while going back to stock due to one or the other needed feature on custom ROM missing, few of them are dual SIM not working, MTP, camera or others. Even if they come back to stock by restoring the stock the ROM via TWRP, sound is not working for many of them. I flashed recent LOS, RR, AOSP and returned back to stock without any problem. I made the traditional backup (yeah not followed the instruction of TWRP backup given in ROM thread
) I will quickly brief on the method. There are 2 methods for the same.
Method 1:
Before flashing the custom ROM
Boot to TWRP
Click on backup
You will bunch of options/partition to backup.
Select only - boot, data, system and vendor and no other partition. (can change the name of TWRP to the Date-Time-BXYZ)
Let TWRP finish the backup (time taken will depend on your data size)
Now again click on backup and this time select only - cust, prod and version (can change the name to Date-Time-others or a per your wish)
Flash custom ROM and enjoy
IF you face any issues and want to return back to stock, refer below.
Return to stock-
Boot to TWRP
Click on Wipe
Wipe System, Boot, Data
Click on Restore
Select the backup media (internal memory/external memory/USB etc)
Chose the 1st back up only i.e boot, data, system and vendor (Date-Time-BXYZ)
Chaneg the file system to F2FS (it was channged to EXT4 while moving to Custom ROM, remember
)
Boot to system.
It should have all sound and other stuff working without any issue.
Method 2:
Use dload method to restore to full stock.

In worst case If you have anything non working, like FM, theme etc, flash the small data file via TWRP.

Try to use the same build number's file for this.
Good luck.
