Question Custom Kernels? Modules for stock roms? - Samsung Galaxy S23 Ultra

Are custom kernels possible? What about compiling modules for stock roms?
I don't know jack about it, but was looking to use a proxmark with my s23 and am told I need a cdc_acm module, or the device /dev/ttyACM0.
Thoughts? Any Education?

Idk about what you're wanting there at the end BUT as for custom kernels it's almost never going to happen. And no magisk module can make a custom kernel. The system doesn't work that way. The kernel boots up before the system even starts and that includes magisk

I don't know why you brought up Magisk? I'm talking about kernel modules. Custom module(and whole kernels) were possible for earlier phones, I had 2 on the s10.
My goal is to be able to use my proxmark from my phone.

[Discussion] Rooting (insecure kernel) and building JB ROM for Player 3.6

Basically what I'm trying to do is make an insecure/rooted kernel and a custom ICS ROM for the Samsung Galaxy Player 3.6. I don't have enough knowledge and experience to do this completely on my own, so if anyone's willing to help that would be great.
For rooting I know that because it's 2.3.6 there's no universal way to root. I've heard that the only way to root 2.3.6 is by flashing an insecure, or rooted kernel, while I'm savvy enough to flash the kernel and/or provide the files, I have no idea how to build one.
For a custom ICS ROM it's the same, I'm savvy enough to flash a ROM and provide files, but not even close to knowing how to build one. I'd like the ROM based off of CM10, if possible.
I'm willing to test out anything remotely stable that doesn't have a large chance of bricking my device. I know the amount of people who are interested in this is small, but we will all be very grateful.
I thought most custom roms automatically allowed the user root access. After all, managing users and permissions is a function of the kernel, which gets replaced when you flash a new rom, doesn't it?
Of course, there is a very good chance I'm mistaken or just wrong. Either way, this is a great chance to learn the how's and why's of droid development.

Sorry if it didn't seem clear, but in the end I'm wanting to create a custom ICS ROM, but right now I'm wanting to at least root.

[Q] Are Kernals restricted to their intented ROMs?

Hi, just wanted to a simple question? Can I mix different kernal builds with different ROMs?
Like I have Carbon ROM with kernal "3.4.11-LGegacy-1.4" right now. So can I try another kernal without changing the ROM?

Not really, no. Unless your ROM specifically says it's compatible with the kernel you want to try.
Otherwise you could be risking bricking your device.
Which is bad.
Thanks Ticklefish for your reply

The kernel, in extremely basic terms, is a piece of software that tells your operating system how to use the hardware of your device. This includes everything from screen resolution, processor speeds, RAM, buttons, all the way up to the OS itself.
Thus, kernels are device-specific. However, kernels can often be used across different ROMs on a single device. Compatibility depends on the kernel and the device. For example, on my Nexus 4, there are a bunch of different kernels, and dozens of different ROMs. Some kernels are practically universal. Some ROMs use stock kernels. Some ROMs have their own kernels. Sometimes kernels will "work" with ROMs, but not fully (like wifi won't work, or something like that). Again, this depends on the device, the ROM, and the kernel.
Just do a Nandroid back-up before trying anything "stupid", and ask the developer(s) of the ROM and kernel in question about compatibility. With a Nandroid, you can always go back (assuming you have custom recovery). You can also just reflash the original kernel, as long as its available.

So kernals in essence are like drivers... say for Windows Seven. You might have different drivers that may work for Seven but not for XP

Newbie question regarding recovery and Magisk

Hey guys,
I mangaged to install a custom ROM on my 9s Note (Curtana). Now I want to install the MIUI stock camera (48mp) module because the one which comes with the rom is quite poor on options. I have many confusions about the next steps and hope to find some help. I posted my questions on the thread of the ROM but unfortunatly did not get any response.
My questions are:
Is it correct that I need now to change the stock recovery to a custom one, for example TWRP in order to install custom addons?
Then I need to install Magisk which is used to install this custom ´addons´?
If this both are installed, will I be a SU automatically?
Will my banking apps still work or stuff like Spotify, WhatsApp? It does now on the custom rom which is amazing.
Is it possible to backup the original recovery partition? Then at any point in the future go back to it?
Can I install the stock MIUI ROM 11 or 12 with a custom recovery?
I would be so thankful if somebody could help me!
Cheers,
Cho
1) if you have installed a custom ROM, chances are you did it with a custom recovery.
2) some addons require root privileges, which can be had with magisk
3)yes, having magisk installed successfully means yiu will have rot privileges
4) banking apps, google own safety net checks and magisk are in a constant race of outpacing each other, magisk seems to be loosing now with tighter controls in newer android version. so dont expect your banking apps to work with magisk anymore.
5) it is probable on some devices with mature development not sure with this
6) not in its stock form, usually people build alternate builds of stock ROM that can be flashed with custom recoveries.

Question Why don't we see any custom ROMs yet?

This is mostly a noob question. I have been out of the phone mod game for years. But now that we have unlocked bootloaders and TWRP, why aren't we seeing custom ROMs? I thought we would see a striped stock rom or something. Sorry if this question is ignorant, I don't mean it to be.
GSIs are a form of custom ROMs, and they run alright on N200. Try one if you dare?
GSIs on N200
The process of flashing alone is conventional, shouldn't even need a thread to detail, but still leaving a thread here for search indexing. With an unlocked BL, flash an ARM64 AB GSI within fastbootd, reboot to recovery, format userdata, reboot...

Truth is, we don't have the source code yet, are still waiting on the unlocked MSM tools to fixed borked attempts, and some parts after just missing still. Be patient. Good things come to those who wait... And read all the other threads.
^^ Bump.
I unlocked my ROM and seem to have ditched the T-Mobile-branded Oxygen OS for the stock version (I probably almost bricked it!). But dissapointed to see no real custom ROMS for this phone when I search...
Not too familiar with how a "GSI" differs from an official ROM, seems to be some kind of OS-skeleton not specific to each phone? In any case, any newer thoughts?
Or are there custom ROMS for the Nord N200 budget phone, and I've missed those threads?
There's this one:

I can't personally vouch for it though, as I'm waiting for a fully working TWRP (or any fully working custom recovery) before doing much experimenting on my phone.

Installing GSI Roms on a A10S?

Almost of the most popular Custom ROMs don't even Support this Phone at all, so I looked up GSI roms which should work on any phone whatsoever, is there a way to install GSI roms on this phone?

Most likely. Install TWRP, then flash any GSI you want to /system.
I have written a guide here but be aware that you are expected to know your way around Odin and TWRP.
