[Samsung Galaxy Tab S6 ROMs, Kernels, Recoveries, &] Aid777:
I am planning to root my SM-T860 tablet this weekend. I have written out a guide for this and believe it's more-or-less correct, I just wanted some clarification on a few points. Thanks to some users on this post for answering some earlier questions .

1.	Unlock bootloader first (the tablet data will be erased after this has been done):

•	Enable developer options in the tablet

•	Enable USB debugging and oem unlock in developer options

•	Download and install “USB fastboot Driver for PC”

•	Turn off the tablet

•	While holding the volume down, volume up and power on buttons plug the USB cable into your PC, you should then enter the unlock bootloader screen

•	Follow the instructions on the blue screen, the tablet should then reboot. Set up the tablet again to get to the main OS screen. Enable developer options again, don’t bother putting any other data onto the tablet because it’s going to get wiped again later.

•	oem should still be enabled but now it should be greyed out

2.	Flash TWRP.tar in Odin (only use the .img file if you’re updating TWRP):

•	Start Odin in Windows

•	Make sure the tablet is off and enter download mode by pressing both volume keys while connecting the tablet to your PC

•	The ID:COM port in the Odin program should light up to indicate connection with the tablet, if it does not try to enter download mode again and make sure you have the latest Samsung USB drivers installed on your PC

•	Select AP only and then locate the TWRP.tar file for your tablet type

•	Untick the Auto Reboot option

•	Press Start button in Odin to flash TWRP

•	IMPORTANT, Reboot the tablet back into TWRP recovery by exiting download mode by holding the volume down and power button at the same time until the screen turns off

Then, as soon as the screen turns off, release the volume down button and quickly press and hold the volume up and power button to force-reboot into TWRP

•	Format data, reboot to recovery again

•	Flash the WETA kernel, (there are two files, one is permissive, the other is enforcing, use ENF unless you know you need PERM), then go back to main TWRP menu

•	Flash encryption disabler file Disable_Dm-Verity_ForceEncrypt, then go back to main menu

•	Untick the mount option in TWRP to Unmount system

•	Flash Magisk 19.4 (not version 20.xx)

•	Reboot system

Be aware, during the first clean boot, the system will hang on building cache, hard reboot after waiting about 3 mins and you'll boot past this (hard reboot by pressing power and volume down button at the same time)

When the tablet starts up you should have Magisk app on the tablet, it should now be safe to automatically update the Magisk installer to the latest version, you could also DL a root checker app from the store.

Things I am not sure about:

Should F. Reset Time be left ticked?

Not 100% certain the button combo presses are correct, do different Samsung devices require other buttons pressed?

What should one do if you were not able to reboot the tablet back into TWRP recovery after flashing TWRP in Odin, is the process described to do this correct? Can you try again with the button combo or would you need to flash the stock ROM in Odin? Would you enter a bootloop?

Do you need to keep hold of the power button when you switch over from volume down (to exit download mode) to volume up to enter TWRP recovery?

How long do you need to keep the hard reboot buttons pressed for, a few seconds or so until tablet is seen to turn on?
