Thank you!

I installed the GSI and it was an easy process. Go to the thread of LineageOS 20 GSI TrebleDroid, download your desired version from the given link. First install twrp (I suppose you know how that works, otherwise just look for a guide online). Then, flash a modified vbmeta.img. On some of the later pages in the GSI thread there is an explanation from @AnonVendetta on how to modify the vbmeta.img accordingly. After flashing it, just proceed with flashing lineage (there are many guides on how to flash a custom rom).

Thank you got it working myself a couple of hours ago! I've created a post with some instructions.

If you can figure out how to use a hex editor, modifying vbmeta is very quick and easy. Frhed is easy enough to use (the one I recommended), because it has a function that goes to the needed offset.
[Samsung Galaxy Tab S6 ROMs, Kernels, Recoveries, &] sosimple:
I tried, and succed in installing the last android 12 rom of samsung (ui 4.1.1) and installing last original twrp and root with last magisk.

I already had unlock bootloader. I'll try to remember the steps i used, if anyone wants to do the same. Feel free to correct me if some step is wrong or not necessary. I'm not sure if everything i did was necessary, i just post what i did and worked. I saw many videos and read many pages here and in other places to have all things needed.

- You need to have downloaded : Latest samsung android 12 rom, magisk, vbmeta, multidisabler, and latest twrp recovery.

1 I first installed in odin latest rom

2 Boot in the rom. I first didn't login to my Gmail but in developer settings there isn't the option oem unlocked. I went in download mode, trying to flash in odin vbmeta file and odin gave me error.

I saw the tablet in download mode show: KG status prenormal.

I Googled it and find out it was because there isn't the option oem unlock. I boot to os again, login to my Gmail account and oem unlock, created..

I went in download mode again, KG status wasnt there at all this time.

I repeated again what was giving me error in odin, flashing vbmeta file, and this time completed without an error.

So you need to login to gmail account (and check usb debugging in developer option ofcourse).

4 I reboot to stock recovery, wipe data and reboot to download mode again.

5 I flashed twrp file in odin.

4 Reboot in twrp recovery. If iyou doesn't do fast enough the key compination, and it didn't boot in twrp, reboot with the key and try again until it boot to twrp. Dont let it boot to android os.

6 From pc move to tablet multidisabler file, and last (i think) magisk.

In twrp select multidisabler and flash it.

7 Reboot to twrp again. Flash in twrp magisk.

From twrp select to boot to os.

If everything went ok, you will see samsung logo. It will stay there some minutes. I wasn't actually knew if it will boot. But after several minutes it did boot. It has magisk. I open it, it had an update, needed to reboot 2 times to have latest magisk.
[Samsung Galaxy Tab S6 ROMs, Kernels, Recoveries, &] AnonVendetta:
Actually, you don't need to log into Google or Samsung or anything. I get the same on my Tab S7 Plus, oem unlocking doesn't appear at 1st. The key is connecting to internet, doesn't matter if it's mobile data or wifi. Then the option will appear. So just make sure internet is connected, then recheck dev options, it should appear. If your bootloader is already unlocked then oem unlocking will always be there.

According to magisk official documentation, patching the stock boot.img is the recommended way to install. TWRP method is the old way and not recommended anymore. Even though it may still work.
[Samsung Galaxy Tab S6 ROMs, Kernels, Recoveries, &] PROXYhx:
Hello,

I've got a few questions about the installation process.

I have successfully rooted my T860 and have been using it like this for the past 3 months. It then happened, 2 weeks after the initial install. The thing I feared the most.. a bootloop cycle had begun. Due to a very stupid misinput whilst fiddling with the kernel, my device was now bootlooping. And it was a pain in the butt, I had lost valuable data in those mere 2 weeks.

I sadly didn't know that there was an official release of TWRP for this model back then. So I kept on using it very carefully up until now. My tablet is currently full with valuable data once again, but significantly more than last time.

Is there any way for me to install TWRP on my tablet without wiping the data? There is absolutely no way for me to create a back up of this specific data without the use of TWRP.

This has turned into some sort of paradox I'm afraid. So, is there a way for me to do this without needing to wipe anything?

Thanks in advance.

Kind regards,

As the OP of this thread has been inactive for quite some time, I've taken the liberty to update the OP with the correct download links.
[Samsung Galaxy Tab S6 ROMs, Kernels, Recoveries, &] PROXYhx:
May I ask you what this custom kernel is better at that the stock one? Would it also work if I flashed it through a kernel manager instead of TWRP, on Android 12?

I'm in a very sticky situation right now and I've been looking everywhere for a custom kernel with great performance for this tablet with no success until now.

I certainly hope that it'll fix most of my problems with this tablet, if not all. Though I am skeptical about the compatibility issues that might arise if I flashed this right now.

I would greatly appreciate it if you could give me a quick reply.

Thanks in advance

Kind regards,

Hello @Mentalmuso, can you perhaps give me the file(s) for a stock or modified kernel for the T860 please? There is a problem with my kernel and I can't afford to reset/reflash everything right now.

Does anyone have fresh vbmeta, multidisabler?
[Samsung Galaxy Tab S6 ROMs, Kernels, Recoveries, &] Arobase404:
Why do you want a fresh vbmeta or multidisabler ?

I haven't been using vbmeta for over a year. In fact I only used it once at the very beginning as I wasn't sure if I had to use it or not and finally I abandoned it with no issue.

Same with Multidisabler as version 3.1 is still working fine with no issue.
[Samsung Galaxy Tab S6 ROMs, Kernels, Recoveries, &] ronny_raygun:
Don't know if this helps, but I hope so.

Got an SM-T865 (Euro model) the other day and rooted/TWRPed it as described here and had the same "can't boot into recovery" problem as plenty of others.

Found out that all you have to do is select "reboot to recovery" from Magisk then DO NOTHING until the red writing appears and THEN press power and volume up.

Bingo! TWRP is there, all backups work and "reboot system" takes you straight back to the rooted (so far functioning) system. Haven't found anything that doesn't work yet.

Thanks for the great work here people - couldn't have done it without you :)

Managed to get it installed using older release .tar and flashing latest IMG. Now need to add magisk which version do I need as all in one zip you provided errors on install via twrp

Edit extracted your IMG from twrp zip and flashed patched with magisk
[Samsung Galaxy Tab S6 ROMs, Kernels, Recoveries, &] Mentalmuso:
To install TWRP, you need to prepatch it with magisk.

Before proceeding with any of this you should be on a pre rooted system, and have magisk manager installed.

Patch the TWRP IMG with magisk, and then flash it.

[Samsung Galaxy Tab S6 ROMs, Kernels, Recoveries, &] comeandgetit11:
Hi, Mentalmuso

First of all, thank you so much for this TWRP for T895,

However, I still have got problem, I've tried many times, but failed

First, I have already got Magisk with Rooted System

and everything work fine, I don't even need to press any combo button in order to boot (including restart)

and it went through "Rooted System with Magisk"

However, whenever I flash "TWRP_T865_3.3.1-5_ODIN.tar" via Odin, and reboot afterward,

-if I press Side Key + Volume Up button -> it goes into "TWRP Recovery"

****-If I choose "Reboot to System" -> it just boot into "TWRP Recovery" Again

****-If I choose "Reboot to Recovery" -> it just boot into "TWRP Recovery" Again, too

-if I press Side Key + Volume Down button -> it goes into "TWRP Recovery"

****-If I choose "Reboot to System" -> it just boot into "TWRP Recovery" Again

****-If I choose "Reboot to Recovery" -> it just boot into "TWRP Recovery" Again, too

-If I do NOT press any Key -> it boot into "System WITHOUT Root" but it take very long time (3-7 minutes) to boot

I don't know what I should do at this stage, because I even try everything,

as I started from "Rooted System with Magisk", and that's fine,

However, like I described above, everytime I flash "TWRP_T865_3.3.1-5_ODIN.tar" -> problem come again (System with Root & Magisk is gone, NO matter what combo button, or choosing any Reboot option via TWRP Recovery)

FYI, I have always check "OEM unlocking" and it is enabled every time.

and one more thing, After flashing ""TWRP_T865_3.3.1-5_ODIN.tar", my ONLY (System with Boot) is randomly taking like 3-7 minutes until finish entering "System without Root")

could you or anyone else please help me out, I really cannot think of what I have done wrong.

Thank you so much!!!
[Samsung Galaxy Tab S6 ROMs, Kernels, Recoveries, &] Mentalmuso:
Did you root the tar IMG? TWRP is no longer magisk patched. It's against magisk rules.
[Samsung Galaxy Tab S6 ROMs, Kernels, Recoveries, &] Mentalmuso:
3.3.1-7

Fixed some recovery_dtbo issues

Magisk is no longer pre patched (19.4 recommended)

* TWRP installer - you may have noticed a zip in the download folder with installer in the name. This is a zip that can be flashed under the modules section in magisk manager. It simply flashes TWRP of your choosing. You need to flash magisk again after installing. But it simply eliminates Odin or TWRP for flashing.

Hi, thank you for the reply,

I used this file "TWRP_T865_3.3.1-5_ODIN.tar" from the op.

so if it's not correct one, could you please tell me, which one should I use, in order to keep both Rooted System & TWRP

Thank you so much ^^
[Samsung Galaxy Tab S6 ROMs, Kernels, Recoveries, &] Mentalmuso:
You didn't answer my question. Did you magisk patch the tar you downloaded?

Regardless the latest version is 3.3.1-7

Download that and root it with magisk manager before flashing.
[Samsung Galaxy Tab S6 ROMs, Kernels, Recoveries, &] comeandgetit11:
Hi, Mentalmuso

I'm so sorry that didn't answer your question, yes I didn't do that "magisk patch TWRP thing"

However, now I've just tried with version 3.3.1-7, however, now I got another problem,

After flashing "TWRP 3.3.1-7 magisk patched" that I patched with "Magisk" myself,

NOW, there is some error about "vbmeta" and I can't even boot into System, or TWRP Recovery, >_<

"FULL Message as below"

partition vbmeta

Reason vbmeta: Error verifying vbmeta image: 0_0_INDIVLDVMT_EDRHS_IMTHSGAUEMSAC

What should I do now, please help me further... >_<

Thank you so much ^^

EDIT: AFTER done it more than 10 times = =" I believe it because of Magisk v20 (which is still not supported by Tab s6 I believe)

how can I stop update to v20??? (I even uncheck the Auto Update in Magisk Manager), but it still shows update to v20

so when I patched "TWRP" maybe it patched with v20??? (so that's why I got the "vbmeta" error, so I have to redo installing SAR (v19.4 as I got that zip file from this thread https://xdaforums.com/galaxy-tab-s6/how-to/how-to-root-tab-s6-sm-t3963539) from scratch and redo all the process

like more than 10 times, so very tired = =")

Anyway it's just my assumption about Magisk v20,

if it's not about the Magisk v20, I really don't know why I couldn't success flashing TWRP for SAR.

Please Mentalmuso or anyone else, help me further >_<

Thank you so much again

Just to be sure, is this still the case?

I'm T860, rooted with Magisk 19.3, don't care about encryption.

Have been using device for months and have tons of apps installed and configure, so don't want to lose anything.

Kinda confused as to what's the best route to take.

Advice?

Thanks!
[Samsung Galaxy Tab S6 ROMs, Kernels, Recoveries, &] Mentalmuso:
Yeah encryption is overrated haha, if things are setup and things work got you there really is no need to update TWRP,
[Samsung Galaxy Tab S6 ROMs, Kernels, Recoveries, &] TiTiB:
I didn't phrase my question correctly. ?

I want TWRP so I can create a backup because I like to **** around with hobbling Samsung as much as possible (and keeping functionality that I deem important, ofc). It's really nice to be able to quickly recover from my sometimes overly zealous efforts—check my sig. And when I said idc about encryption, I mean idc either way.

???? me sometimes

I just want be sure I'm using current best practices.

Thanks, again.
[Samsung Galaxy Tab S6 ROMs, Kernels, Recoveries, &] Mentalmuso:
TWRP installation changed

Download folder

It is now possible to reboot rooted and reboot recovery without the button combo. To achieve this we need to flash custom kernel to boot.img and flash magisk via TWRP. TWRP now, should not be patched with magisk either. In the downloads folder, is a kernel zip for your device. This needs to be flashed in TWRP followed by the flashing of Magisk zip (19.4 recommended.)

After that, I would reflash an unpatched TWRP.img from within TWRP to recovery partition. This eliminates magisk from the recovery side of things, which isn't needed anymore.

Process from stock (rooted)

1. Flash TWRP.tar in Odin

2. Reboot directly into TWRP

3. Flash Kernel zip

4. Flash Magisk zip

5. Flash encryption disabler if desired.

6. Reboot system (not recovery)

Process from existing TWRP

1. Flash unpatched TWRP.img to recovery

2. Reboot recovery

3. Flash Kernel zip

4. Flash Magisk zip

5. Reboot system (not recovery

0. reboot to download mode

1. flash new firmware via Odin

2. reboot to system

3. connect to internet and confirm OEM Unlock is set to "on"

[Samsung Galaxy Tab S6 ROMs, Kernels, Recoveries, &] d.cortez:
apologies for quoting myself, but i want to list the steps i followed to flash ASJ1 to my TabS6, install TWRP and root my device...

-- Created a TWRP full backup of my device, bold items represents added steps i followed to complete update process

Steps to install firmware ASJ1

0. reboot to download mode

1. flash new firmware via Odin (used HOME CSC file)

2. reboot to system --> this failed so i had to factory reset

2.a Factory reset with stock recovery

2.b reboot to system to finish the ASJ1 frimware install

2.c complete the Android setup process

3. connect to internet and confirm OEM Unlock is set to "on"

4. reboot to download mode

5. untick the auto reboot function

Steps to install TWRP and root

0. Flashed twrp_t865_magisk_patched_v1.tar; i took this step to get to TWRP and add the ATT CSC information to the /product/omc folder (allows me to use HD Voice (VoLTE) and Video calling)

1. Flash TWRP_T865_3.3.1-7.tar file using the AP tab in Odin

2. Once flashed, boot into TWRP, don't boot into system just yet ---> i waited quite a while for TWRP 3.3.1-7 to boot

3. Flash Kernel WETA_Kernel_T865_1.2_SJ1.zip

4. Flash Magisk-v19.4.zip

4.1 Flashed Disable_Dm-Verity_ForceEncrypt_05.21.2019.zip (changed my mind to stay encrypted because i can do this after setting up my device)

4.2 Rebooted to Recovery to confirm i could see internal sdcard

5. Reboot system (not recovery) ---> i waited quite a while for this as well; didn't time it because i stepped away for a few minutes

6. first clean boot, hangs on building cache, hard rebooted after waiting about 3 min

7. Restored my TWRP data backup created with twrp_t865_magisk_patched_v1, rebooted my tablet and Android started the "updating app X of 438" process. process hung @ "updating app 438 of 438" so i repeated step 6.

Tablet rebooted with security intact and all features working as they were before i started. i'm rooted, too!

Yeah I was about to say, you need to make sure you connect to the internet and check OEM unlock every time you go from stock, to flashing modded
[Samsung Galaxy Tab S6 ROMs, Kernels, Recoveries, &] Mentalmuso:
I don't know what you've flashed so just start by downloading and flashing the stock firmware for your device from sammobile or use the windows program "frija" to download it. Flash AP.tar to AP, BL to BL etc.

Make sure you flash T860 firmware to a T860 device, and not a T865 for instance
