Long story short : There was this custom OP2 ROM which already had it's network issues fixed but I thought it wasn't fixed. So I flashed the OOS 3.6.1 firmware for better network and Volte but now I'm facing a issue where the network just drops off and my 4g internet fails. This is due to me flashing that what wasn't required. Only a reboot fixes it and this is problematic.
Q] How do I extract the firmware from the my custom rom and make it flashable ? I don't want to reflash or dirty flash the rom.
Links would be appreciated. Thanks in advance !
The issue is not the firmware, custom rom doesn't have firmware included and the only firmware you should use is the latest 3.6.1.

Lollipop Update Blocked downgrading.
It's not going to work. I think that using a nandroid backup made by somebody else should work.
I had to upgrade from a KitKat ROM, in which my firmware was (NC4). Since I had to flash a stock Verizon lollipop factory ROM my firmware has changed to ( N900VVRUEOF1). Does anyone know if I can flash a Custom ROM that has a different firmware ? or know of a ROM with a compatible firmware ? Thank You in advance.
I have an EUI 5.8.21s stock ROM zip, flashable with TWRP, from x727 (modded for dual sim x720, but can be modded back) I also have a modem for 19s. I hear the latter will fix my issues with my phone under custom ROMs, but am a bit nervous about modem flashing. My phone came with stock 18s and no OTA upgrade available.
Will the stock ROM also fix this, and also, will it relock the bootloader? If it relocks the bootloader, can I flash the 19s file that unlocks the bootloader without side-effects for custom ROMs or it not unlocking the bootloader?
I know this is a lot of questions, you don't have to answer all of them, just answer with the right solution for this problem.
I went ahead and flashed the modem... hope this solves my issues.
It didn't solve the issues. What now? Is the stock ROM I found here, mentioned above, bootloader-unlockable or will it trap me in it? I think I want to give it a try, but want to go to custom ROMs; perhaps afterwards if the modem/baseband on it help.
i had a similar (but not same) question like this.
You can try to flash CN stock rom and then reflash US modem. The US modem can be found in many threads.
BTW, i did not notice anybody post a modem file with a 'newer' version no.
Hey guys, i searched a lot, on google and xda, but i think i couldn't find the answer to my question.
I have the latest unofficial LineageOS 8.1.0 Oreo installed, with TWRP.
At home my phone is losing wifi signal every few minutes and then it reconnects again, as far as i know this was already a problem with stock Samsung ROM installed. Now, since i rooted and installed TWRP and LOS i ask myself, if there is a possibility to update latest firmware / modem / booloader without wiping the device, respectively flash the whole Samsung stock ROM with Odin and root / the device again?
To be simple: Is it possible to flash extracted parts of the official Samsung FW package with odin or flashfire to update wifi modem / firmware without losing data and wipe my installed LOS rom?
All i could find was how to do this with official rooted samsung ROM but not how to update with an installed custom rom?
Maybe somebody can help me out here Thanks in advance!
EDIT: I found that somebody made twrp flashable modem and bootloader files! Thatd awesome, you can find the thread here: https://forum.xda-developers.com/galaxy-s7/how-to/guide-onelatest-stock-fw-csc-root-t3702963

I think you can update the bootloader and modem without wiping anything. Just flash thru odin. I'm on a custom rom by the way.
Had lineage os flashed stock Tom now I'm in a bootloop and when I try to flash twrp only official binaries are allowed to be flashed
So why not flash an official one?

Hi, some time ago after playing with custom roms and microG i had simmilar problem. Download the official firmware from for example samfirm and flash all parts BL, AP, CSC and CP with following data wipe. If it doesn't go, try anotger build. (i tried the newer version ASIE, but i had there same error as well, so i flashed ASG8 - it was the official version what custom rom was based on)
