[Q] custom recovery location in the file system - G2 Q&A, Help & Troubleshooting

I found a collection of bin files for the stock 24a partitions and after overwriting the "recovery" partition twrp is still installed.
Which partition do I have to overwrite with stock to clear out TWRP?
Or a simpler question, Where in the file-system is TWRP located?

[Q] Recovery and File System

I'm running unlocked stock 183.46.10. The file system for my data partition is F2FS, and I believe it should be EXT4. I found this out by trying to install Bliss, and not getting past the boot animation screen. The suggested "fix" is to change data file system to EXT4.
Do custom recoveries "remember" the file system that was backed up? If I back up my system and then change file systems, when I go to restore, do I need to revert back to my original file system?
[EDIT] I answered my own question - TWRP does "remember" the original file system backed up, and will issue a warning that the restored system may not boot if you are restoring using a different file system. I went ahead and restored my backed up system, but now, my data partition is using EXT4 instead of F2FS. So far, all seems to work OK.

System Partition File Format...

I recently installed the CM13 rom using TWRP recovery... While trying to wipe the system, data, cache partition, somehow the system partiton got formatted to some other file format (this i found later when i tried to flash the stock rom some days later)...i found i couldnt flash the GPT.BIN file... And also the rest of the stock rom files... I searched alot and understood the GPT file cannot be flashed if the file format is changed... I want help on this... Whats the system file format so that i can format it through TWRP... please help...

[Q] Create ODIN flashable zip from TWRP backup

dear members,
I need help in creating a odin flashable file from TWRP back for SM-900F
I have seen some guides on net for creating the zip file, but i have two system.ext4.win files named as system.ext.win000 and win001
I have attached screenshot of twrp backup folder showing all files available.
After flashing custom ROM, camera has always failed on TW ROMs for me.
But i have TWRP backup of my original ROM in which camera was working.
can somebody please guide how to create a odin flashable zip.
Problem is that if i restore via TWRP , then it enters into a bootloop.
not sure why. any ideas how to resolve bootloop would be useful. Do i need to be on the same bootloader and modem as the backup being restored ?
thanks in advance ....
could be the bootloader, but most common thing thats caused bootloops on my G900p is the presence of those pesky android file folders on internal and the sd card. Delete them in twrp, wipe and then try a restore

system partition has unexpected contents

Hey I have tried to flash lineage os by grarak with no success. I am currently on android 7(test key) if I use twrp 3.0.2 phone gets stuck at patching system unconditionally, with twrp 3.0.3 I got this message system partition has unexpected contents after ota update, so I wiped system, change system format (in hope that I will pass this message) still wasn't able to flash it. Is there any way to solve this? It's possible that system partition is smaller than rom system?

Creating a flashable zip from a twrp backup for data, system and boot

I have a moto e4 qualcomm and I want to turn my twrp backup which contains the system, data and boot partition into a flashable zip.
How can i do that?
I saw an old guide but it does not cover how to do it also for the data partition and only talks about the system and boot partition. Any ideas?
