Get ROM from a rooted device - Android Builders Collective

Hello,
I want to ask the following question that I don't have knowledge of. I've been compiling and installing ROM's on different android devices and Android versions (AOSP, Lineage, etc). What I would be interested in is if I have a rooted device, then removing the Google apps, then creating a custom ROM out of it?
Why I am considering to do this is because I have some specific devices (with keyboard) where I was able to install GSI Lineage or AOSP instead of the stock rom (full of Google). But I am facing random issues with the phone, which I think might be because the original ROM might have those fixes included in the ROM but not the other ones. Maybe it's just some kernel modules or something else.
Was anyone able to create a ROM from a rooted device?
Thanks for the help.

[Q] [Question] Universal Android Firmware?

Why there are many custom ROMs for specific device and why there (if any) is not any universal Android firmware that can be installed in any Android device like normal computer do. I also seen there are problems like camera not working, bugs etc. Why?

Yeah, this is all about drivers, device-specific features and non-standard modifications. Manufacturers like to be original.

Installing a ROM of a different Android Version

I'm planning on replacing my stock 4.4.2 touchwiz ROM on my rooted I9505 Galaxy S4 but I want to get a custom ROM that is running Android 6 or higher. I have never done this before so I'm wondering if there are any precautions I should take.
To my knowledge the standard process for installing new ROMs is:
1. Get into your custom recovery
2. Make a backup of your current ROM
3. Wipe system, data, dalvik cache, and cache
4. Flash the new ROM
I heard somewhere that if your current device is running some android version (in my case 4.4.2), and the new ROM you're flashing is a different android version (6.0.1 or 7.0), then when you try to restore your original ROM there might be problems.
I also read somewhere that for new roms you also want to update your radio and bootloader? None of the big youtube tutorials I've watched even mentioned these things. If someone could elaborate that would be amazing!
One last thing, if anyone knows of good ROMs that's compatible with my S4, please let me know I'm looking for something that is running the more recent android versions (6 or higher), very stable so that it can be my daily driver, and has a good camera app (I hear a lot of custom ROMs have really bad camera apps).
Thanks for the help

Recommendation for Oreo and maybe Custom ROM

I'm not really a very advanced user, but always had rooted devices and two that I flashed Custom Roms. This is my first Samsung, finding Touchwiz to be very different from what I used before.
I bought the S7 (930F) and had the news that it was going to be updated to Oreo, so I decided waiting for the update before tinkering with it.. But the update never came. Finally this month Samsung released the update for my region, so I would like to know which would be the best way for me to start finally using my phone that I bought for over 2 months!
My phone is still with Nougat, is it better for me to get the OTA or to flash the Firmware I downloaded from Sammobile? Any of these methods better than the other in preventing errors? I always found in PCs that a fresh clean install was better than an update, but with mobiles I don't have the experience to say.
My main objective is to experiment before doing a debloat as I'm still not sure what might be useful for me on Samsung's bloat (you are welcome to point me what is useful and what is not).
I did see that some of the Customs ROMS have different camera apps and some people were complaining about this, I particularly liked the S7 camera app and the Pro option, that's what holds me back in flashing a Custom ROM atm.
I would like to Root and I find Unlocked Bootloader to be useful to have Xposed Framework and other things that I can do having it.
As I'm a relative newbie, what would you guys recommend me doing? Please help
tl;dr: I want to have Oreo, be able to debloat, want to root and unlock bootloader, not sure about Custom Rom.
Lineage if you want basic and simple (sort of like stock Android). Resurrection Remix if you're a customisation nut (not a slam... I use RR).
If you wonna full samsung u need flash base firmawre custom roms only 8.0 android
If you dnt need samsung integration (pulsometr doesnt work) you can flash 8.1 roms try cosmic os or Lineage 15

question about ROM - Samsung S9 SM-G960F (PHN)

hi everyone, I am new to this forum.
i've been interested in rooting / mods for my old Samsung s9 to give it a new life.
I did so by rooting it using the TWRP app in combination with the Magisk V23.0
now what happened was that i was downloading some random apps yesterday and for some reason the phone went on bootloop...
i accidentally deleted the system without making a backup lol... a little stupid of me...
now it keeps telling me that i've no OS on my phone. i was thinking that i could easily find the ''un-edited'' or simple version of my original OS. but i've looked through many sites without succes.. either looks 2 good to be true or just fake...
is there anyone who can advise me on what to do? i just want my phone to work with any OS right now... but which one is the cleanest or best to use? i do prefer a newer os like 10
thanks in advance!
If you still have access to recovery mode, your best choice would probably be installing LineageOS. It's the most lightweight ROM and many ROMs are based on Lineage. From what i can see, your phone is no longer officially supported.
I found this one based on Lineage 18.1 (Android 11). Before installing, take a look at the bugs, working, and installing sections.
And don't forget to install the Google Apps after installing the system and before rebooting.
that looks crispy. i appreciate your quick & good advise. can you tell me wether i can still run Magisk on it?
Yes, you can still flash Magisk or any type of root with both the OS and the GApps.
what i'm consider about is, wether a region code CRC matters?

Is there a good custom ROM for the Galaxy A51 that focuses on privacy and security?

There are some custom ROMs for the Galaxy A51, but so far I have not seen a ROM without proprietary Google and Samsung software that also gets regular security updates. It would be nice if someone could answer me.
Thanks
Hello, as I modified my phone, bricking it and restoring it, the firts custom ROM I flashed was SuperiorOS.
And I also use it.
The feature of this ROM is, that you do not need to flash any Gapps: all needed system applications, like gallery and phone are already included!
The problem is, that this ROM does not support MTP, but I resolved it by flashing a custom kernel.
Recently I have decided to replace all systems apps by simple mobile tools ones; and it still works!
So, the answer is, SUPERIOR OS
