How to ROOT and, but...

Hey there. I'm searchin' for TWRP for my A11 and no use.No one compile it and nobody can't write full f*****' guide how to build TWRP without any config file (or how to create 'em for building from 0). But honestly I'm not about TWRP.

Why do we need TWRP for Android 10!?

A: Samsung lock phones /system partition to Read-Only state. You can get root but you can't mount your partition as Read-Write, make changes in it. It's only waste of time.

How can I install ROOT for my samsung A**?

A: Very simple. I suggest you using Magisk Manager for it!

What do I need and what do I must do?

A:

1. You need unlock the bootloader of your phone (data will be lost).

2. You need original USB cable (from box of phone).

3. Yon need last firmware to your phone. (I'm using SamFirm or Frija)

4. Windows 7 or higher.

5. 7-Zip

6. Odin

How:

Stage I: Bootloader.

0. Remove all Google and Samsung Accounts

1. Make data backup (for recoverying)

2. Go to Settings -> Developer Options -> ADB Debug (set Enabled) (Search in web how to get Developer options Settings menu)

14. Validate that's you've done everything right: Find OEM Unlock if toogle is gray and not responging to your actions then you've done right!

15. No download firware to your PC.

16. After you had downloaded firmware for your phone you'll fave few files you need file with prefix "AP_" open it with 7-Zip.

17. Get from it file: "boot.img.lz4" and put to some location at your PC.

18. Pack your "boot.img.lz4" with 7-Zip to "boot.img.lz4.tar" (YOU MUST USE *.TAR ARCHIVE TYPE)

19. Install Magisk Manager to your phone and put your archive "boot.img.lz4.tar" to location: Internal Memory/Download

20. Connect to WiFi and run Magisk Manager.

21. Make Kernel Patch with Magisk: Select: "Install Magisk" -> "Patch boot image" -> in file picker navigate and select "boot.img.lz4.tar"

23. When it's done in folder "Internal Memory/Download" will be magisk_patched.tar copy it to your Windows.

24. (On PC) Run Odin as Administrator. And in tab "Options" unselect checkbox "Auto Reboot"

25. Turn off your phone and wait for 10 seconds, then Press and hold VOLUME UP and VOLUME DOWN and plug in your USB from PC to phone.

26. Phone will ask you what do need to do, just click VOLUME UP and you enter into Download mode
