I have face one more problem


Why i need to port twrp for every android version?

Why it's not supporting any Android version? When i tried to switch marshmallows to lollipop, recovery won't work and if recovery work then boot stuck.

Can you help me to build twrp for my device not only for any single android version.

that's because kernel in each of the different stock recovery are not the same and NO, no one custom recovery will work for all the different android versions your phone has

Twrp working perfectly but i have facing one more problem when i tried to flash rom zip file it says......

could not detect filesystem for /dev/block/bootdevice/by-name/system, assuming ext4
mount: failed to mount /dev/block/bootdevice/by-name/system at /system: no such file or directory
unmount of /system failed; no such volume

Suggest me something to fix this issue or explain why it's happening. Thanks

Might be a mount point problem from the zip you're flashing or the TWRP. post a link to the TWRP so we take a look. If the stock recovery is different from the one above then provide that too
