Magisk on SM-T350 without TWRP on 7.1.1? - Samsung Galaxy Tab A series Questions & Answers

I want to root my Tab A with Magisk but can't install TWRP without the device blackscreening when booting into it.
Is there any way to install Magisk without the use of TWRP on this model? If so, how would I go about doing this?

Oneplus 5 TWRP and Root Issues

Oneplus 5, Official ROM, H2OS, Android 7.1
1. First time, I followed https://forum.xda-developers.com/oneplus-5/how-to/oneplus-5-unlock-bootloader-flash-twrp-t3624877 and successfully install TWRP and root using Supersu. I can goes into TWRP recovery without any problem. I notice that the supersu I installed in a systemless one, some apps can't get root access, like AD Away, Titanium Backup. But most apps can work with it. I used the one of the two root method in that tutorial as follows:
For Users who want to remain Encrypted:
1. Boot into TWRP Recovery and allow system modifications.
2. Swipe right and enable modifications.
3. Select your preferred Language, Tap “Never show this screen on boot again,” and Swipe allow modification.
4. Navigate to Install and select Magisk Or SuperSU to root OnePlus 5.
5. Swipe to confirm the flash
6. Reboot System

2. After several months I want to upgrade the original H2OS to new version, so I unroot in Supersu first, when it ask me if I want to recover Boot Image, I say "Yes", and say "NO" when ask me if I want to recover Recovery Image. Then I upgrade to the new H2OS v13 (Android 7.1) using the Full package through TWRP, after that I reinstall TWRP 3.2.1, it was successful. But it doesn't ask me to allow it to make modification. I tried to install Supersu 2.82 and 2.82 SR5 using the same method as in tutorial, at the end of "Booting Image patcher" it shows
.........
-Calling user ramdisk patch script
---Failure, aborting
-Unmounting /system and /vender
-Done

Click to collapse
Then I reboot to recovery, it return to official REC, not TWRP, and system says there is no root.

Just use the latest universal codeworks recovery and flash it via fastboot.
For root i suggest use of Magisk over Su, the latest 15.3 works fine for me.
What is the codeworks recovery? Is it "twrp-3.2.1-0-cheeseburger.img" on https://twrp.me/oneplus/oneplus5.html?

No, it's the -universal- one from here https://forum.xda-developers.com/on...overy-twrp-3-2-1-0-oreo-oxygenos-5-0-t3725723
I can flash universal TWRP and Magisk 15.3. But Magisk show "SafetyNet API Error"? How to fix it?

Rooting help for OnePlus 6T 9.0.15

A little background: I was rooted before updating my OnePlus 6T from system settings, then after updating (through system settings) I no longer had root and TWRP recovery so what I did was flashed TWRP following this method now I do have TWRP recovery but I am not sure which method to follow for the root process, and I have few concerns as below:
Should I flash Magisk now if so which version and which method will work for 9.0.15?
Before flashing Magisk should I flash Magisk uninstaller as well?
Do I have to flash TWRP again after flashing Magisk?
I might be asking dumb questions but I don't want to mess it up.
Greetings.
Just straight up flash the latest Magisk version, worked for me. Flash it through TWRP.
Why would you flash magisk uninstaller? I mean, I suppose it's optional?
No, you don't have to flash TWRP again.
Cheers.
Flash Magisk.
Next time, without rebooting, use Magisk mod 'TWRP A/B retention script' (search for it in Magisk modules list) just after flashing OTA via local method, and then without rebooting yet, in Magisk manager install again Magisk selecting 'other slot after OTA' option. Then only you reboot, all babies intact and in good health

[QUESTION] Update from OOS 10.0.1 to 10.3.0

Happy new year to all you merry people
Going to update my international OP6T from 10.0.1 to 10.3.0. I have TWRP, cutom kernel and Magisk with several modules. I don't care about TWRP, only need Magisk and custom kernel. My plan is:
Clean flash full 10.3.0 from here
reboot to bootloader
boot TWRP, install magisk, ElementalX kernel
reboot to OS.
Is it a correct way or will it brick the phone? Maybe omebody can suggest a better way?
Thanks in advance
It should work. Tho you can flash Magisk from Magisk Manager. There is an option to flash to Other slot after an OTA.

So just install OTA, install Magisk to another slot and reboot? Should I uninstall all Magisk modules first?

Gosh...
The official way to do it is always the same, no need to ask at every update how to do it
Flash OTA local update
Don't reboot
From Magisk Manager flash latest twrp as a module if you want twrp
Don't reboot
From Magisk Manager install Magisk on other slot
Reboot
That's the official (cf Magisk GitHub) way to do it. Period. Do what you want with Magisk modules only a very few of them can do harm. I don't touch them. And don't uninstall Magisk before OTA it's useless on our phone

How can I root G9500 android 9.0 Snapdragon with Magisk?

I want install Magisk on Samsung Galaxy S8 (SM-G9500) Snapdragon android 9.0 Pie.
I know the step to root like this:
1. Unlock OEM. (Success)
2. Flash twrp (Success)
3. Wipe Format Data (Success)
4. Install Magisk (Success)
5. Reboot (bootloop) Failed
I use the offical twrp (twrp-3.4.0-0-dreamqlte.img.tar), I try lots of Magisk(Magisk-v18.1.zip,Magisk-v19.3.zip,Magisk-v20.4.zip) . But no success. I don't know why? I think the twrp version is not important. Which Magisk verison is right?
I also find the way to decrypt data with "RMM State Bypass" and "No Verify Opt Encrypt ZIP". but it's also failed. I think this way is for the Exynos phone.
I don't know how can I to do for rooting it. Is there any one can help me? Thank you.
Having the exact same problem with the SM-G9500, seems like everything installs flawlessly but get a bootloop after installing Magisk. Am able to install and boot with TWRP + no-verity, but adding Magisk to the install just puts it into a bootloop.
