You can flash TWRP two ways, either directly from an existing TWRP install, using the linked TWRP.img file. Or you can flash using Odin and the TWRP.tar file.

You will need a custom kernel with dm-verity disabled to be able to boot up afterwards. You will also need to disable encryption and format data to be able to read from the sdcard (encryption isn't supported).

The flashing process is as follows.

Get yourself onto stock Pie firmware, using Odin to flash the complete package. Before proceeding. Boot up and make sure you have OEM unlock switch and its activated.

1. Boot into Download mode and Flash TWRP (Download) using Odin (use AP)

2. Immediately boot into TWRP after flashing takes place, hold vol up and power.

3. Format data partition (wipe/format data)

4. Reboot recovery

5. Copy WETA Kernel + Encryption disabler + Magisk zip to device. - (Download Kernel - Encryption disabler)

6. Flash WETA Kernel + Encrypt disabler + Magisk zip.

7. Boot up system, if it hangs on Samsung logo after 3min perform hard reboot.

8. Connect to internet and go to dev settings and check oem unlock is present before any rebooting.

** Custom kernel is universal for all bootloader v4 firmware.

[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] neuer31:
Some things to note:

0. Requirements are:

USB Cable (Samsung Tab S4 default cable recommended)

A computer where Odin works (ie. my AM4 X370 Ryzen 7 system did not work, maybe some driver issue?)

Best is to put encryption disabler & Kernel onto the micro SD card in the Tab S4 already, you can flash from SD card in TWRP!

1. Flash TWRP in AP slot - beware if you did not untick Auto Reboot, it will immediately restart and you miss 2.

2. Hold those buttons before the vibration kicks in, otherwise you are too late

4. I couldn't do that from TWRP itself for some reason (it just shut off), but button combo worked perfectly

5. [Edit] Do that before hand, I recommend the micro SD card you can put into the Tab S4

6. I flashed encryption disabler (V2) first, then you have to flash the kernel image, flash it to BOOT!

7. Don't just wait 3 min, my Tablet booted after 10 min without issue! I had this before aswell, you just need to give it more time!

Question: Can I update Magisk with this?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
Yeah flashing magisk should be fine once your data partition is unencrypted.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] speed_boy:
F###, thanks, bro.

Just flashed it as recovery and have this now.

Can you delete this suggestion? It should be flashed as Boot, GOD!

Every step seemed to work for me. flashed twrp in odin, directly to twrp, flashed encryptor, reboot to twrp, data is mounted, flashed kernel, all fine booted, set up all. But after next boot data is unmounted and no root and all. Tested now 4 times. What am i doing wrong.? Any ideas to help? Badly(?) i'm now, on sj6 and can't also not go back to sg6. Thanks

edit: It's a T835. Followed all your steps of post 2 with your files and magisk 20.1.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
You don't.mention formatting data
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] makiao:
Thanks. Yes i wiped data like in your guide. maybe i need to set it in advanced wipe? i just swiped there as i remember right. It's called wipe data/cache or so.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
You need to Format. Not wipe. If you are properly formatting you will be asked to type "yes" to complete
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] makiao:
Ohoh, you could be right, maybe i made this mistake, Will give it a try tomorrow again.

Thank you!

Just flashing csc will do it. I'm not sure on home or non home though

Not gonna lie, this should be mentioned somewhere in your guide. I've been pulling my hair out for the past four hours trying to figure out why fastboot wouldn't work for the life of me. Was almost at the point of reflashing ARH5 to try that, but didn't want to get rid of the current Android 9.0 on it. Figured I'd scroll through and see if anyone could point out something, and lo and behold, this little trick did the job.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] RainbowXQF:
Thanks for your twrp mate, great job! BTW I'm using T835 and when I tried to flash twrp into my tab there's some connection issue happend with my odin and my computer, when you hit strat in odin, it may shows "SetupConnection" or "Initialization" and nothing happend after thant. if you guys have the same issue, you may found some solution in Google like change cable/port/computer etc. But actually It's because your computer USB port are USB 3.0, Some Samsung devices doesn't recognize that. you need a USB 2.0 port to connect to your device, I bought a USB 3.0 to USB 2.0 converter and everything worked perfectly. Hope this infomation may help you guys. And I hope you can authorize me to translate this full guide into Chinese and post into Chinese community. Thanks again :D

Working with t837r4?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] William James:
My tablet is on T835XXU4BSJ6, Kernel version 4.4.153-17096871, date 31 October 2019. I have tried several times to root it, using the both the method in posts #2 and #8 here, and various other methods found on different sites, all without success. I can install TWRP with no problem, but that's as far as I can ever get. When I try to flash either the WETA or the DM Verity disabler, TWRP returns an error "Failed to mount /data".

Am I correct in assuming that this is because the kernel I'm trying to flash doesn't match the firmware? If so, is there any updated version of WETA or DM Verity disabler that will work on the 31 October 2019 firmware? Also, I understand that it is not possible to roll back to an earlier version of the firmware, say T835XXU3BSF4 of 14 June.

Any help would be greatly appreciated. Thanks.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] William James:
Never mind. I solved the problem by copying WETA, DM Verity disabler and Magisk from my PC to the tablet's internal storage (not the SD card) after formatting data. The installation process then went smoothly and my tablet is now successfully rooted.

Stuck on "Set Warranty Bit : Recovery" Screen

[MENTION=4553200]Mentalmuso[/MENTION]

I've done the process as said in the instructions and made sure to have the rom for my tablet downloaded in case anything were to happen. I also made sure to have OEM Unlock and USB Debugging enabled before starting this. I flashed the TWRP provided in the OP and holding Pow + Vol Up did nothing to get the tablet out of Download mode and into TWRP. I found out that holding Pow + Vol Down can get me out of Download mode, but made sure to hold Vol Up as soon as I was out, and now I'm stuck at this screen. It's been sitting like this for about 15 mins, holding Pow for any length of time doesn't do anything, neither does holding Pow + Vol Up. Holding Pow + Vol Down did reboot the tablet, but it still goes to the same screen afterwards. I can't get into Download mode, TWRP, or into Android at all. I'm positive there's a fix for this, but I haven't seen one in this thread. So, is there a way for me to fix this or at least a way to get into Download mode?

Edit: Ok it turned out that I used the wrong TWRP tar. It also turned out that holding Pow + Vol Up + Vol Down brought me to the "Verification Failed" screen where I could reset the device and try again, which worked. I used the correct TWRP tar and it worked correctly. Sorry for the inconvenience.

I am afraid but after flashing with Odin in AP tablet boot well but after going into Recovery SD Card is 0 byte and get boot loop rebooting system.

I even tried to format data after flashing TWRP no go.

I am rooted with the magisk method link below and installed TWRP after rooting

https://topjohnwu.github.io/Magisk/install.html#samsung-system-as-root

So it looks something is wrong

Having the same issue.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
What firmware are you on? What device? I can't help without crucial info like this

Also, did you flash encryption disabler?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] veekay:
Pretty sure this is going to be the same as mine - SM-T830 on the just released Android 10.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
You patched the AP file etc? I'm.not sure why you followed that guide. Snapdragon devices don't need to do that. I'm not saying that recovery hasn't borked something, but you should follow the method outlined in post #2 or in the telegram thread. Magisk is able to patch and boot from the boot.img on this device after simply flashing magisk.zip from twrp.

I suspect you booted rooted using the button combo correct? Or am I misunderstanding you?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
Did you root by patching AP with magisk manager?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] veekay:
I also followed that guide, figured they changed things in 10. When my wifes Samsung was last updated the AP patch method became the only way to root so it made sense.

I'll just wipe things and do it the way I always have with 9
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
If you could that would be great, I'll need to know if I have to tell t830 owners to wait, t835 has tested fine and I can't imagine why t830 would be any different.

Even though it's supposedly system as root, nothing has really changed from what I can see.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] veekay:
Works just fine that way - at least it cuts down on all the time and hassle that having to patch takes
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] veekay:
Very odd, but every backup I have tried to make and restore on the latest version fails on the System partition with the "extractTarFork() process ended with ERROR: 255" message

Of course this failure means I have to start over and wipe/reload the system again.

Older backups still restore just fine
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] arlequin2k3:
Hello Mentalmuso

Just a question to ask yourself. Once I patched the AP file with magisk, I replace it in odin and I add the CSC and BL files. But when do I use TWRP and how do I install it? Thank you for your rest. ;)
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
Just like I mentioned to the other recent users, why are you using that method to root? I don't state that as a method to use on this device anywhere in this thread.

Please just flash twrp and flash magisk through twrp. It's that simple. Follow guide in post #2 but with the updated files
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
Thanks for reporting this, I just want to get a better idea of what's going on here so I can fix it.

You can successfully make a backup of Android 10 system, with twrp 3.4 but not restore it?

Though you can restore an older backup of system, presumably of Android 9 system, using twrp 3.4 still?

Does that Android 9 restore allow you to boot? Just curious
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] enotar:
OK, I will follow post #2

What is the new Encryption disabler if there is a new one or V2 is still OK

Thanks
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
I just copied a version of the one I use for all my devices into the download folder.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] veekay:
That is correct. It always fails in the system restore. The android 9 backups restore just fine and will boot, but they end up looping - I'm guessing since the base is already on 10?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] enotar:
Well after doing all steps missing a bunch of apps and SOD

So I will try one more time
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] enotar:
Well redo all and still SOD when tablet go to sleep.

But I know tablet is ON for the notifications sounds. Only the screen cannot turn it on.

Rebooted and this is worst than I thought; nothing really works, touch screen, it is not responsive, try to get a log with logcat but even that cannot get root and it is really unusable.

Not sure what it wrong. I used all files in 10 folder + Magisk 20.04 zip file

I think something is wrong with kernel or encryption disabler.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] veekay:
A few more tests on the backup/restore. I did get one attempt to actually restore without error, but it only happens after restoring a backup made with the previous version.

I can load a previous TWRP (3.3.1-4) and make a backup of the Android 10 system and then load the latest TWRP release and restore it (and boot).

I get the same error trying to restore the A10 backup in the older TWRP
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] enotar:
I think I sorted out.

One more time mix kernel

My bad
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
What was it?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
That's strange, I'll look up the notes for 3.4.0 as I haven't changed anything in the build config. Must be something in the new source
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
Do you mind going into twrp and taking some screen shots?

Go into backup - take a screenshot

Go into file manager - go to / - screenshot

Mount system, go to / - screenshot.

Thanks
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] veekay:
Like these?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] enotar:
Sorry for that it was a mix kernel, I use another Kernel, I think this is the now the time to cleanup my Rom Dir.

BTW speaking of backup Has file name change in 10 and permissions? It looks titanium backup cannot restore any file, restore is not even available even if Titanium find the file.

Is it possible to flash only or need to redo all?

Maybe Kernel- Encryption disabler- magisk on top of what we already have to not have to reflash with Odin?

Your thoughts?

Thank you very much Metalmuso to keep our tablet up to date
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
The reason there is a version that is an img file, is to be able to simply flash the twrp.img from within an existing twrp installation.

The only reason you'd need to flash the kernel, magisk and encryption disabler again would be if you were on complete stock firmware

From within twrp, simply flash the new twrp.img to the recovery partition, done.
