Is there any way to desamsung the s21 ultra with stock android and keep the safteynet bits for baking apps etc? Just find the phone has been so so bogged down with bloat etc I just want stock android if possible. TIA

Install a custom rom (such as lineage), and patch safetynet using magisk?

SafetyNet Compatible ROMs

I maintain a few devices for my family members, and as I'm seeing more and more apps requiring SafetyNet checks for compatibility, I'm afraid I'm going to need to change my typical phh SuperUser setup I've been using in favor of using Magisk for root, since it can pass a SafetyNet check.
Are most ROMs out there able to pass SafetyNet if rooted with Magisk? I'm currently using OmniROM on most of my devices, but the dev team has explicitly stated that they don't support or recommend rooting. I know that a few ROMs specifically claim that they pass SafetyNet with Magisk. Is this the exception, or the norm?
What do I need to look for in a ROM to know if it will pass these checks?

I think you need to have release keys and approved build fingerprint
Look at "Xiaomi SafetyNet Fix for Beta & C. ROMs" Xiaomi SafetyNet Fix for Beta & C. ROMsMagisk module. Use it as a base for your phone.
You can also look at the similar module for my device (LeEco Le Max 2)

to see what changes should be made to Port the module to the new device.

How do I install Xposed on a stock ROM?

Here are my details:
Google Pixel
Android Pie
Stock
Bootloader unlocked
I know thatXposed does not support Pie yet. So, I am willing to install Edxposed, instead, or any other fork of Xposed for Pie.
So, how do I install it? Do I download the stock ROM and modify it somehow?
All I really want is Xprivacy, so if anyone also knows of anything else like it for Pie and any custom ROM that includes said alternative, then please tell me what they are (alternative to Xposed and Pie ROM that includes it).

Installation of edxposed is done through magisk.
They are not in the download section of the magisk repo and have to be installed manually in the modules menu with the + button. You will need the 2 files to flash in magisk + the exposed installer from this thread.
If it works you will need xprivacylua ( not xprvacy) which Marcel is currently working on to improve for pie with I believe edxposed.

https://forum.xda-developers.com/xposed/modules/xprivacylua6-0-android-privacy-manager-t3730663
As for any other xposed versions for pie I have not heard of any others
Note: edxposed does not work for me on my s8 yet so I am not sure about your pixel.
I can confirm that EdXposed works on Pixel, I have it installed.
Like how @spawnlives said, the installation process is simple enough.
Just be careful what modules you install, a lot of them is not compatible yet and you could end in a bootloop and have to uninstall the modules via twrp.
I suggest you to read the list of compatible modules here.
If you're interested in a privacy module, looks like xprivacylua is already compatible with EdXposed.

Looking for best ROM with Root 'switch' for snapchat, et al.

I have a 3T, a3003 version, 9.0.5 OxygenOS stock upgraded.
I'm looking for a ROM that's easy to switch root on and off, so that I can use snapchat and banking apps. Are there any ROMs that support some kind of root switch? I've seen apks that are meant to do that for other phones, but nothing specifically for OnePlus phones, or the 3T in specific.
Failing that, I'm just looking for a recommendation on a daily driver kernel/ROM.
I use Snapchat, Google Pay and 3 Polish banking apps with Magisk and EDXposed enabled no problem, so I think this kind of switch is not really needed

Just go for any ROM and use Magisk for root support, then add your root sensitive apps under Magisk Hide under Magisk and they won't see root feature.

questions about the right ROM for Note 8 (SM-N950F)

Hello,
my friend has a Samsung galaxy note 8 with the model SM-N950F and he was thinking about giving me his phone to install a custom ROM for him, the phone is running stock ROM.
my question is what is the most stable android 12/13 Rom ( AOSP ) that doesn't require rooting and has banking apps and the pen working fine, also what is the latest stable TWARP and Odin that works for that model ( because I had SM-G530h and some Odin versions didn't work with it ).
one more question is it available to go back to Stock ROM once again using Odin like with old Samsung phones and where can I find a trusted source as Sammobile doesn't seem to work for me for some reason?
thanks in advance for your help.

Your question is a contradiction. You're asking whether you can use a custom ROM without root but still pass Play Integrity and other checks? This is not possible. Simply having an unlocked bootloader makes your device fail. To pass Play Integrity and be able to use banking apps, the Universal SafetyNet Fix module is required for use with Magisk. Further, AOSP does not include any of the "frills" that Samsung preloads into their firmware, meaning that not all features may work, including the S Pen. If you want to try AOSP anyway, you can follow my guide here to install an AOSP GSI.
As for returning your device to stock using Odin, yes. Sammobile is a good source, but if it doesn't work for you, you can try Frija or Samfirm.js to download the firmware directly from Samsung's servers.

Frija is faster and I recommend it. SAMMobile forces users to register to their website and limit your DL-speed.
It's not strictly required to use Magisk. Some Custom ROMs by default spoof SafetyNet Attestation to BASIC and don't need Magisk.
But in the case of Custom ROMs like LineageOS (which doesn't spoof/hide the Unlocked Bootloader on purpose!), or Stock OneUI ROM, you do need to use Magisk + "MagiskHide Props Config" Magisk Module and set the fingerprint to Note8. If Note8 isnt available as a fingerprint, use SafetyNet-Fix Module.
Also, I don't use my Note 8 anymore, but we have Custom ROMs for Note8. I see we have LineageOS 20.0. Why use GSIs? They are much more unstable and buggy.

LineageOS is largely developed as a GSI. Yes, in many cases, it is bundled with a device specific kernel as a complete ROM, but for Project Treble compliant devices, a Generic System Image is just that - a single generic system image that does not have any device specific functions and can be used with any kernel on any device. In that regard, the official AOSP GSIs are very stable, and any issues are usually involved with the kernel, not the system image.

To be able to use Banking Apps, the following practices are good.
Passing SafetyNet (you can check this with YASNAC from Play Store).
If you don't pass SafetyNet, use Magisk with one of the 2 modules mentioned above.
You may also need to enable Zygisk, Enforce DenyList, and add your Banking Apps to Magisk DenyList.
I use a Xiaomi Poco F3 with ArrowOS Custom ROM, it already contains patches to force SafetyNet to BASIC, and so I dont need any modules, but only Zygisk, Force DenyList, and add my Banking Apps to the DenyList and reboot ^^

My Xiaomi Poco F3 (2021) supports Treble and GSI's are not at all usable/daily-drivable. Scratchy Sound, Missing Vibration etc..

What GSIs have you tried? I suspect that the device kernel is not fully Treble compliant.

Generic System Image releases | Platform | Android Developers
developer.android.com
The official Googley ones. Tho I don't mind, since I use an AOSP Custom ROM anyway (on my Xiaomi phone). My Note 8 is kept on OneUI 1.0... i miss the "Samsung Experience" dayz.. Yknow, the OS that came after TouchWiz. It had a rather professional-looking boxy design. Don't like the Huge padding and Rounded Corners of OneUI. The modern OneUI versions are also eh. Due to Samsung stuffing additional apps like TikTok and other rubbish as pre-installed apps.

Huh. I've used both the "pure" GSIs from Android CI, as well as the Android Developer GSIs on my Tab A 8.0 with the CUK4 kernel. Everything works like it should. Make sure you're using the correct architecture and bitness for your device - most are arm64 - but in the off case that your Xiaomi isn't ARM, there will likely be a lot of issues.
Remember that while a Treble kernel should run any GSI, you still have to wipe data. You can't go from OEM firmware to GSI or vice versa without a data wipe; that cause a a lot of stability issues.
thanks for the replays and information guys regarding official releases of AOSP ROMs I haven't seen one that is higher than android 9 ( which is mainly the reason why we want to install a higher version due to compatibility issues with the company portal apps ) so any idea what is the most stable ROM for that model running android 10 or above

Question Mods to suggest?

Hi all, I am new to this kind of phone with stock Android, my last was Redmi Mi 9T with Magisk and Lsposed, safetynet passed and CustoMIUIzer.
With CustoMIUIzer I could disable the power menu while locked, now with my new Pixel 7 I really want to know which mods I can download, what apps do you recommend? For safetynet bypass I can simply install the usual mods from Magisk?
Thanks!

SafetyNet is no longer relevant as it has been replaced by Play Integrity. See this thread.
Keep in mind that some modules may cause bootloops after updating. YMMV.
