¤ Build Custom kernel (KernelSU) with a Linux subsystem within Windows 10 By yourself is the best way if you are interested in new root management.
Why?
On Android 10+, system partitions might no longer be able to remount as read-write. For devices use dynnamic partition, it is nearly impossible to modify system partiton as there is no space left.

Why Read Only? Can't make R/W (vndk lite).​Almost GSIs builds are RO now. Because R/W are so big not suitable for... (Most devices have small system partition which might even be less than 3GB.)
Howto install "KernelSu (0.5.7) A13 for SM-T225 (kernel source T225XXS3CWC2)" ?
Thank to kernel-patched from DEV "zillion".
This method does not require you to have TWRP, nor does it require your phone to have root privileges; it is suitable for your first installation of KernelSU.

7. install " KernelSU Manager APK"
8. Download: magic_overlayfs module. https://github.com/HuskyDG/magic_overlayfs/releases

- give root (superuser) permission to your root file manager in KernelSU Manager.
》Open and edit " /data/adb/modules/magisk_overlayfs/mode.sh"
Change "export OVERLAY_MODE=1"
" export DO_UNMOUNT_KSU=true "
reboot
Opem termux or any terminal

Definitely correct about the 3in1 - not a chance! And also definitely do not use the decryption files! And, true, the stock or any other pre-existing recovery will not go away! Unfortunately, if you are using a simple magisk patched rom, it won't do the backup because it does not seem to ever recognize the data. The Fastboot works but, for the moment, it is as easy to use a FastbootD patched recovery. Finally, I was only able to reboot to system just once after flashing the twrp. I think that might have been because I did not try to decrypt after the initial flash. Been at this for 4 days. It's given me a new appreciation for how difficult this is! As a non developer (I am a lawyer), I got used to the TWRP process taking no more than 20 minutes!

It's exhausting. And I was going through this process (not root, I need that), to be more able to make the device do what it is advertised to do: make calls. I might give up on that!

uses gsi A13(QPR-1) such as elixer 3.6 etc. Assistant can make a call from your contact.

You were never supposed to post this, considering the github source code wasn't updated according to this twrp image.
edit: Thanks for removing the twrp image from your post, I'll be updating twrp when things get more stable.

Make "YAAP 20230604 unofficial GSI " R/W super partition with KernelSU".
YAAP is a project founded by Adhitya Mohan (@poad42) and Ido Ben-Hur (@idoybh) with the goal of staying close to AOSP in design goals, offer a clean interface, do as much as original development as possible and avoid becoming a kitchen sink and cherry picked mess.
Whats New?​
Synced with latest sources of YAAP.
Synced with latest Trebledroid patches.
All builds are RO now (sorry every build so huge now that i had to. Otherwise it wouldnt fit in anyone's devices)
Example ( Features)

Kernelsu is supported for one ui, but one ui no need to use overlayfs module cause super partition of one ui are rw.
