Dumb question - is stock firmware AOSP, OMS, or ? - Google Pixel 2 XL Questions & Answers

As the subject declares, I know it's a dumb question... but what is the "stock" firmware classified as?
Are there any custom ROMs built on the stock firmware?
I'd love to install a custom ROM, but so far nothing reliably supports Sprint, so I'm wondering if a modified stock exists.

As of right now there are only custom AOSP ROMs. There was a tweaked stock based ROM awhile back but it's not active currently. OMS is a Mod baked into some custom ROMs. It helps in theming with Substratum. I'm not sure of the specifics though.

SGH-I747 Kernel flashing 101

So I have got a question that maybe many others have yet to voice or address (maybe it's just me, and I am delusional). In any event, I am not new to rooting and flashing ROMS. I am also familiar--at least conceptually--with what the kernel is and what it does. For the purposes of this post however, I should mention that I have not ever flashed a custom kernel and am unsure as to why one would or why there is more than one floating around. I have been vacillating back on forth between stock and custom kernels....it seems like in order to flash this ROM you need this Kernel, or that ROM flash that Kernel. I want to learn and to know. I would really appreciate feedback on this.

Kernel's are installed or "flashed" in the same manner as a custom ROM, either through CWM or Odin. Kernel's just add an extra level of customization, most people use custom Kernel's for overclocking although they also have many other uses.
Kernals can also highly affect battery life and the speed of roms. The kernal has to match the kind of rom. Samsung kernals go with samsung/touchwiz based roms. Aosp kernals go with aosp based roms like cyanogenmod and aokp. There are a few jellybean kernals and those will work for the current jellybean aosp based roms. Samsung will eventually release their own jellybean update and when that happens expect to see jellybean samsung kernals made for roms based on samsung jellybean.

[Q] please help

Hello all. First I want to thank everyone for still being around to help, especially on such an old device.
Anyway, I recently bought one of these and got it rooted via odin. Currently that's all I've done to her. I have been looking over this forum, android forums, and Google in general prior to posting, I want to solve problems on my own, but when I can't, I'm not scared to ask for help. And I need help with a few issues. I will seperate them, to make answering them easier.
1) is twrp not available for this model?
2) if not, the only other recoverys I can find is Phils TouchWiz, and ClockworkMod recovery touch 5.8.1.5. I wouldn't think these are the same, which is suggested? Also Phils Touchwiz was last updated (that I can find) to 4.1.2 which is where I currently am, am I want to go to 4.4
3) I only see 2 ROMs listed on here, and 1 is one of the ones I was thinking of using in Dirty Unicorns. The other I was thinking about was CyanogenMod. Which of these two is suggested?
4) I have no service on this phone, as its my tinkering device. The only thing I need to work is WiFi. That being said, do I need to flash a new modem?
Do I need to flash a new kernel?
Thanks for any help you can throw me. I know there are lots of tuts for all these questions, but frankly they are all very old, and this stuff changes by the day...
1. Yes but this device has recovery and kernel built in together, this recovery is only for flashing / wiping, other than that, it is not usable with other custom roms unless the devs build it to use that
recovery along with the kernel.
2. It's the same as question 1, For Touchwiz Jellybean, you'll need a recovery kernel that supports the android version and firmware, otherwise it wouldn't work or boot up, Agat's Source GB27 for GB27 Touchwiz ROMs. Or specific AOSP Kernels for certain kernel build updates ( versions are compatible with the build date of the ROM's Original Kernel, meaning it only works on certain ROMs that are updated with the same kernel build, for example, A custom 0.0.25 will not work with stock 0.0.26 because there was a major update change in the kernel that'll make 0.0.25 not usable on it. If you use a kernel based on a specific date on an AOSP ROM that frequently updates the kernel, it may not boot up. )
3. The AOSP ROMs that are being updated at the moment are the Teams that do Nightlies. So Cyanogenmod is the only AOSP ROM that's being updated weekly for this device, I have not checked on the other ones.
4. No need to flash a modem if you don't have data service, however it may help either way when using WiFi due to dropped connections, stability etc. For AOSP, use any ICS modem, for Touchwiz, use the same android firmware modem.
Flashing a new kernel is not needed unless you don't like how the stock kernel performs whether if it's power saving or performance. AOSP kernels are kind of limited as the ones out now work with different build dates of the ROMs, Touchwiz has a couple, but Agat63's Source Kernel is recommended by everyone for GB27.

Flashing ROMs with FlashFire

On my Sprint G4 I was and to flash Xposed with FlashFire. What is preventing devs from making ROMs we could flash the same way? I've read that it needs to be running on the stock kernel, is there anything else or is this just not a dev friendly phone?
It would need to be running stock kernel and the rom itself would need to be stock based. Basically, it could not be built from source. It could not be AOSP based. It would have to be modifications made to the existing stock ROM. As of right now, it's very unfriendly to developers. That doesn't mean this can't change in the future though. People had made some kickass roms for the G2 that were stock based.

Few questions about possible mods and custom ROMs

Hi Guys,
Just wanting a few questions answered if possible for when I get my Pixel 2 XL. I do not want to root the device.
On a custom ROM (Such as LineageOS flashed with GAPPS) , will the Google Camera app work fully as expected with HDR+, as on stock? If not, i'll probably want to keep stock.
When ROM's become available - How can I identify the ROM's that are stock with additional features, or ROM's built from AOSP - I've seen "AOSP" in thread titles, but what am I looking for ROM's built from stock? Hope this makes sense.
Aside from using an app, do you think a Mod can be made for stock that can enable Scrolling Screenshots? Such as; https://www.youtube.com/watch?v=34DQVZx74TE
Anyone?
Check the 6P page and open some of the ROM threads. They list all of the features. If you've never used any of the custom ROMs before give it a try. If you don't like anything just try another or flash stock image. I'm sure once you find one you like though, it will become a necessity. Pixel stock android is smooth, but the ROMs add to the experience IMO, not take away.

I already have. I've flashed Lineage OS and Paranoid Android. I believe they are both AOSP though. Can you provide me with a thread to a ROM that is stock based, and advise what you seen to confirm this?
@Nightmare79 , did you manage to get portrait mode working for the back camera on AOSP/Lineage Roms ?

If it is not AOSP based (or based on rom that is AOSP based), it should be stock based

Question Constant Re-flashing

Hey, I'm a flashaholic and I'm a bit annoyed at why stock has to be flashed all the time if you want to go to another ROM?
Any future workaround?
stock at miflash will do its job to clean all modified partitions specially in a/b section, custom roms and aosp based roms didnt do that
