Limitations/OTA updates after installing TWRP? - Samsung Galaxy S8 Questions and Answers

Hi,
I recently came up with the idea of installing the Stock Firmware on my S8, along with TWRP, but without root or anything like that.
Basically I just want Stock ROM + TWRP.
Will this limit the system in any way? Will banking apps still work, can I still get OTA updates, etc.?

Will this limit the system in any way? - Generally no but Knox related apps won't work like secure folder, shealth, samsung pass etc. Tripping your knox is permanent and can not be fixed.
Will banking apps still work - I can't say to many banks apps out there but i would say generally yes.
can I still get OTA update - No not with TWRP installed. You will have to manually update the device.
The problem with TWRP is it can't read encrypted devices. This is why you need to format data in TWRP to unencrypt your device. So backup your phone before formatting data.

Can't root anymore

Hi All,
I had obtained root via CF-Autoroot and was using it with xposed for the last few weeks without issues. I took the lunge and tried to install phh super su, magisk systemless root. so the nightmare begins for me and i'm hoping it's an easy fix!
My system is still encrypted (I believe because TWRP can't see the system) SD card is fine. I've wiped my device a few times already and am hoping I don't need to wipe it again(prior to this setup).... So currently it's running fine without root access (How I hate android without root!!!)
- I've tried flashing Supersu zip in TWRP and it's failed - I believe it's not supported yet for encrypted devices.
-I've tried using the original CF-Autoroot method I used initially.
Both methods, it boots up straight away (no optimising apps) and after installing supersu app from playstore, it says no binaries found.
What are some ways I can inject root without wiping my device?
Please help me! Thankyou!
Maybe go back to the start and flash original FW through Odin and start from scratch, so you have a fresh phone to work with.

That's my plan when I get home tonight. I want to flash the original firmware file my phone started with (I'm assuming it won't delete anything?) and then run through the root steps again.. if it doesn't work, I'll wipe my phone and make sure I get rid of encryption this time..

I think you will only lose stuff if you do a system reset after installing the original FW.
I only have had to do that on my tab S not my Edge after coming from a custom rom as I got slow down.
Resolved: flashed original rom and obtained root with cf-autoroot.
If someone has detailed instructions for magisk systemless root and xposed, it'd be much appreciated.. i want to have the option to use android pay or play pokemon go if i wanted. Thankyou

Root then UnRoot?

Hey everyone,
So I just want to go stock because at this point it's the only good option for keeping Android Pay. It's become too troublesome to try and trick the SafetyNet into thinking im not rooted and I honestly don't use root much aside from (force doze). My big issue is I'd like to go to completely stock October security update, but I don't want to lose some of my app data and I hate setting up all my apps again. This is where Titanium Backup comes in handy...
Can I flash the October stock images, flash twrp, flash supersu, install tibu, install apps and data, then uninstall supersu?
The only problem I worry about is that last one, how do I completely wipe supersu after I'm done so that it will pass the SafetyNet?

Yes. Either uninstall in SuperSU or fastboot flash system and boot to wipe SuperSU away.

Thanks! I didn't even think of just flashing system/boot again. Easy. I remembered there was a "unsu.zip" at some point, but it doesn't appear to be "supported" so I wasn't sure if I should use it. Flashing seems like a cleaner solution.
As a side note I installed SuperSU and Suhide.zip for now, it seems to work great....only a matter of time I suspect.

Questions around Encryption (root, OTA, backups)

Hello,
I just ordered my first OnePlus and should receive it by the end of the month. Like all my previous (and quite old) phones, I would like to root it for several reasons and I found the native encryption needs to be disabled in order to be able to root the phone. Fair enough.
Since I never had to deal with encryption on my previous phones, I was wondering if you could tell me more about the consequences:
1) once the phone is rooted, can I enable the encryption again without hassles?
2) once rooted and (hopefully) encrypted, how will I have to update my phone? Flash the full OTA everytime (no partial updates allowed on rooted phones if I understood correctly)? Can I do this without disabling/re-enabling the encryption? After the full flash, will the data & cache be wiped or will it be hassle-free?
3) I generally use Titanium Backup to backup my apps (hence the need for root access) and copy the files on a network drive. Am I correct to assume that native encryption of the OP5 will not affect this process (either during backup or when the files are copied to the network drive (encrypted)?
Thanks for your help

First of all native encryption will still work when rooted. When you root using supersu or Magisk the encryption will stay. When you get your phone you first must boot to fastboot and unlock the bootloader. Doing so will erase data so do it as soon as you get the phone. Second you will need to flash TWRP. Wipe factory settings and flash Supersu or Magisk 13.3. I prefer Magisk. Once in setup you will need to put a password and fingerprint to get the encryption started. After that your all set. To update the rom just head to downloads.oneplus.net and download the correct rom for Oneplus 5 and flash it over TWRP then flash Magisk/Supersu after. I prefer using [ROM] xXx NoLimits 2.0 [OOS][OP5] ☆ Speed/RAM optimized ☆ because it uses stock oxygen os rom with better performance and battery life. Plus extra features like debloating. But other than that you will not lose encryption when rooting. Only when you want to install custom roms for right now like (LineageOS, RR, AOSP).

EngineerMode unroot?

back when engineermode exploit backdoor 'thing' whatever you want to call it, was still a thing i seized to opportunity to gain root access, however since then magisk hide has begun failing me and i would like to either find a way to update magisk from v14.0 safely, or to unroot completely (preferably without wiping) as this has started being problematic. I am on the latest oxygenOS update and i used this guide to root (i originaly linked it here but apparently i cant do that, it was on github, called OneplusRoot by a fella named aldur.)
If anyone can help id really appreciate it.
Thanks in advance
Since One Plus removed engineering mode I'm surprised you were able to update OOS and maintain the exploit. Why don't you just unlock your bootloader and root the proper way? Your phone won't melt if you do.
I would like to avoid wiping if possible. I too am surprised at the persistence of root after at least 3 OTAs. At this point I no longer really need root and would rather my phone run smoothly without some applications crashing or not running due to root.

As long as your system boots, and you have root, install the latest magisk manager from the magisk thread, and it will prompt you to update. As long as you give magisk manager root access you should be able to do a "direct install" and reboot and should be up to date. Back up your data first though, I'm not responsible for your data loss (but this worked for me)
Same to unroot. Magisk has an uninstall option that should fully unroot you

Well my system doesn't boot with root. I have to manually mount something and start the magisk service.
Which is why I'm not sure how to update as I've been told the updated version has a different file structure that the one I'm on.
were you able to unroot? i think i am in the same boot right now, on 4.5.13 with magisk root by engineermode, if you were successful please tell me how

When I ran out of options,I unlocked the bootloader (wiped the device), and the new system was unrooted, i then installed Nolimits rom based on OOS 5.1.2
I asked on another thread and another user told me that if you accepted the complete zip update of the OTA prompt the updated system would lose the root, but you wouldn't lose your data or apps, which is nice, but keep in mind you are more probable to have worse performance or battery than clean install

I can confirm this is not the case, i have been updating as the updates roll out and i am now on 5.1.2 and still able to get root access through adb with a locked bootloader.

Well the alternative is another thing i read but can't find, and honestly can't recommend unless you find in too, is that you can delete the apk and the magisk image(don't know which one, this is how bad i remember this), then rebooting would remove the root.

After one of the recent updates, magisk hide started working again and my apps are no longer crashing. It is strange but i guess this situation has turned out favourably after all.

Just want to install one app as System app...

I have a stock xt1766, which I use primarily as my kid's Pokemon Go phone. That app is often updated to detect root (despite Magisk), so I need to remain unrooted. But I need to install one app as a system app.
Is there a way to do this without rooting, or, if I do root the device and install my system app, is there a way to de-root and retain the system app? I recall there was a method called "kingo root" or something, but not sure if it's trused of effective on this device...
Currently on NCQS26.69-64-5, getting prompted to install NCQS26.69-64-8.
Thanks for any advice!
Mike

You might be able to root with magisk, install your system app, then use fastboot to flash the stock boot.img. which could unroot your phone. But it may not be able to boot because of dm verity or even forced encryption. Kingroot will not work on this device, and is most certainly not to be trusted since it sends your device info to unknown Chinese servers. The only way to successfully unroot, that I know of, is to flash the stock firmware. Which, of course will remove any system changes.
So, short answer, not likely.
