OTA updates on rooted M31? - Samsung Galaxy M31 Questions & Answers

I rooted my phone with Magisk using the Magisk image patching method so now my phone is everything stock + magisk root (no custom kernel or recovery) and a few root applications/modules such as Vanced, ViperFX and adAway.
Oddly enough, I have received a push notification from Samsung about the availability of the Android 11 update. But I don't feel safe to OTA update my phone because of root. So is there any way I can update it without losing any data and without losing root?
Thanks in advance!

Yes, I am looking for that also.
Any one?????

First, you never should update when you are rooted. It may soft-brick your device. And also, if you are looking to root after OTA update, the best thing you can do is downloading the stock firmware and flashing it through ODIN. Then, you can patch Magisk. I don't know if you will lose data, but I recommend you to backup your files.

The update will fail on rooted device.
And if you install it manually you'll lose root. I've been using the full OTA for the past couple of months:
https://developers.google.com/android/nexus/ota#shamu
It's very simple - instructions on that page - and doesn't touch your data, so it's a seamless upgrade. When it's complete, you can then flash TWRP and use it to reinstall SuperSU. 20 minutes end-to-end.
(And what's the "8/29 update"? Do you mean MOB30W, which has been out for a week or more?)
hiya, i'm on stock 6.0.1 rooted w/ twrp recovery. i haven't updated my system since MMB29S.
my question is can i jump to MOB30W instead of all the steps in between. if i can, can i flash the OTA update instead of the full image?
thanks
Yes to both. You'll need to reinstall TWRP and reroot.

does oxygen updater unroot after updtae?

i got root and i want update via oxygen updater, my question is if after the update the app un-root my phone and i need to root again?
Yes, OTA updates will unroot the phone, and also replace TWRP with stock recovery (unless you take actions otherwise).
My recommendation: You can just download the "full update" zip, flash in TWRP, then root with SuperSU/Magisk before rebooting. This will not only root the phone again, but also keep TWRP on the phone. You can find the full update file, and instructions here: https://forum.xda-developers.com/oneplus-3t/how-to/official-oxygenos-5-0-1-android-8-0-t3728119
Also note, that if you are going to Oreo (which is assumed) and presently on Nougat, you will need a TWRP version which supports Oreo. Updated (supports Oreo) version of SuperSU or Magisk is also required.
Don't see a point in using "Oxygen Updater", when there are better means for root users. In fact, I've never used or even heard of "Oxygen Updater" before reading your post! And I had to Google it, to see what it even was!

OTA update with rooted device?

Hello all,
so I have a op3t with SuperSU. I was wondering when the android P update comes out eventually will I be able to OTA update and keep root, or will I have to reflash SuperSU(Using temp TWRP environment).

You will definitely have to reflash SuperSU.

What he said. That goes for most updates of most Android devices (need to root again after an update).
Further, a new Android build (particularly a major update, like Oreo to P) will often require updated root methods. Since SuperSU development is basically dead, it may not work on Android P. You may need to move to Magisk root method (not a bad thing).
Best way to apply updates on rooted 3T, is to get it from the following thread and basically follow the install instruction for root users on Post #3 of that same thread:
https://forum.xda-developers.com/oneplus-3t/how-to/official-oxygenos-5-0-1-android-8-0-t3728119
I would also advise to backup your data before updating, as a clean install (wipe data) is not unheard of (possibly even recommended), when installing major updates.
Note that failure to flash Magisk/SuperSU after applying the update, will not only cause you to lose root, but also lose TWRP (will be overwritten by stock recovery if you reboot before flashing a root file or alternately a modified kernel).

Rooting options for the S10 family

I need to get something straight, as I didn't quite get it. So the options for someone who'd like to root his S10 are 3:
1) Rooting with Topjohnwu method: This will get you root on the stock rom, but will keep the default recovery which is pretty much useless if one wanted to flash a custom rom.
2) Rooting with a prepatched version of TWRP and then, if desired, flash any custom rom (compatible with the TWRP version installed). This method is said to be less stable that the previous one.
3) Install TWRP after rooting with john wu method and then using it to flash custom rom.
First of all, is all this correct?
If so, then one has to choose between rooting safely, but keeping his phone stock, or rooting and then installing twrp and then flash whatever he desires.
Hopefully, somebody will be so kind to clarify this that is an unusually complicated situation about rooting this phone! I already regret passing my perfectly rooted S9 to my son
Thanks for whatever help you'll be willing to provide.
Cheers
I would say you summoned it up nicely.
The advantage of stock Magisk root is you can e.g. use Substratum, Magisk modules and update monthly security releases by yourself but, of course, no Custom ROMs.
The advantage of TWRP Magisk root is clearly the Custom ROM possibility but here you cannot update the monthly security releases by yourself and are dependent on the ROM creator to release the security updates.
I had been using Topjohnwu Magisk root on stock rom since released mainly to use Substratum/ some Magisk Modules and did the AP-patching everytime the monthly security was released.
However, doing the November security AP-patching something went wrong and I ended in boot-loop. So thought, as I had to reflash anyway I would try TWRP/ Custom ROM - I went with yash92Duster's lightrom / geiti94's magisk TWRP both which I find very stable.

One more doubt, if I may ask : once rooted the safe way, if I wanted to install twrp I would need to find the build that is compatible with the already patched firmware on my phone? And then only the roms that are exactly for the same build?
This is the most complicated rooting process that I have ever faced. And I've been rooting my phones and tablets since a very long time
Thanks

Can I just disable and uninstall magisk and take the OTA update to update my Pixel 5?

I am stock, rooted. I want to take the April update. Usually I follow the steps here and flash the full image, but can I not just the disable the magisk modules I have, uninstall magisk, take the OTA update, be unrooted again, and then root?
Will that not work? Or do I HAVE to flash the full image update?
Thanks!
Just download OTA like a normal person and patch inactive slot via magisk manager before rebooting. simple as that. But you should definitely disable all modules before reboot.
