T830 latest stock root - supported? - Samsung Galaxy Tab S4 Questions & Answers

Looking to update XAR (USA) Tab S4 - Not finding much recent root info regarding firmware builds released in say the last year.
Is Stock rom with root working on latest Android 10 Rev 5? I believe T830XXU5CVG2 is the latest for USA T830.

I currently have Android 8.1 (M1AJQ.T830XXU2ARJ3) + Magisk 25.2 + TWRP 3.6.2_90
Are the older guides with encryption disabler relevant still? If a previous guides discussing ~2020 Android 10 builds is that same encryption disabler compatible?
I'd like to avoid odin full stock flash all together. Can I patch stock rom AP with Magisk and just flash the patched AP with TWRP? (And wipe internal storage)
Any pointers be helpful. I've found few older guides but wanting to flash latest stock rom which is why I'm a bit hesitant.
Also came across this post that mentions issues with latest Rev 5 and Magisk ? https://forum.xda-developers.com/t/...tab-s4-sm-t835-android-10-one-ui-2-1.4441257/
Thanks.

Will this work to update to latest Android 10 Rev 5 -T830XXU5CVG2 ?
Currently Android 8.1 + magisk 25.2 + TWRP 3.6.2
1) Stock rom extract - patch boot.img with Magisk app
2) Backup TWRP 3.6 recovery.img
3) Re-tar patched boot.img + recovery.img to AP MD5. Re-tar entire stock ROM.
4) Flash patched stock ROM with TWRP.
5) Wipe internal data and reboot

Nice. Works for me
Magisk and Data
Thank you for share your work TheCapesCrew. I Just download the rom and I should flash it today.
I'd like to know if it already comes with magisk or if I can follow the standard procedure to install it.
Should I use the boot.img inside your rom, or the original from ASUS website to add magisk to the system?
And there's anyway to flash your rom without data loss?
I'm currently with version WW_ZS551KL_15.0410.1812.95_0 version with magisk 19.2 and TWRP 3.2.3-0-Z01G on my Zenfone 4 pro.
Thank you so much!
You should be able to flash right over. I would stick with my bootloader since it matches the kernel version and recovery kernel. The recovery I included has the correct kernel also. I actually compiled a twrp that's newer. 3.3.1, just haven't published it yet.

How to install Q roms on a device with P fw and TWRP installed? (SM-G960F)

Hello friends
I'm trying to flash custom Q roms in TWRP on my S9 (SM-G960F), but have received the same error message for any Q rom:
ERROR:
Vendor image on the device
is NOT compatible
Expected Android 10 vendor
Click to expand...
Click to collapse
I've only been able to successfully flash P roms, namely the Pie-based LightRom.
Based on the error message, it seems I need to update the firmware to Q before installing custom Q roms?
I've also seen some roms note installation requirements like "ROM Firmware Required: OneUI 2.x", which is new to me (have not seen a TW/OneUI ver requirement for roms I've used on S4, S7, N8).
May I ask someone to explain the steps required to install Q roms (eg, Havoc-OS) coming from P firmware? There seems to be some assumptions in most install instructions I'm not aware of, maybe since I am on older FW. (I am asking here, since I did not find instructions in any of the Q roms I tried)
So far, all I have done to the phone since unboxing it was to install TWRP 3.4.0, following the official guide for Exynos S9.
I am guessing I need to download latest official firmware image from sammobile or something for my device, and flash it in Odin. Is this correct?
If so, can someone explain the steps so that I can have latest FW for my device while maintaining TWRP and not bricking the device?
Thank you for your help
Extra info
(Snapshot from LightRom rom)
One UI version: 1.0
Android version: 9
Baseband version: G960FXXU6CSG4
Kernel version: 4.9.59

UPDATE:
I installed latest firmware from Sammobile, flashed it through Odin following their instructions, reinstalled TWRP, and am now able to flash Q roms.
For those who have stock rom < Q, I would suggest updating firmware through OTA before flashing TWRP. If you cannot OTA, download the latest firmware from Sammobile and flash it through Odin following their instructions, then flash TWRP, then you can flash Q roms.
So:
Update firmware through OTA or via Odin with latest firmware from Sammobile.
Flash TWRP
Flash whatever rom you want.

Root OneUI 3.0

Is there a guide for rooting oneui 3.0, i´m asking this question because oneui 2.x has android 10
Did you found solution to root android 11?
I know for android 10 but not for 11.
I manage to root tricking the lz4 files which is the new type of extension in Android and for this you can not root in a normal way. I followed this guide
Fix Oreo Firmware Installation Issue in Odin for Samsung Devices - DroidViews
Android Oreo has finally made its way to Samsung's latest S series flagships, the Galaxy S8 and S8+. The Oreo update brings with it the usual Android Oreo features such as Picture-in-Picture, redesigned Settings app, etc. It also brings with it Samsung Experience 9.0 which is but a fancier name…
www.droidviews.com
After having the 4 stock files modified without lz4 you must flash them with Odin.
After you take the modified AP file and patch it with Magisk.
Then you flash again stock using the patched AP file and the rest of modified files but you must not select autoreboot in Odin. When the flashing is done you must exit download mode and imediatelly enter in Recovery mod but better use this guide

Trying to downgrade to Android 8 or preferably 7 with Odin

I have long tried to downgrade my phone SM-G955F to Android 8 or 7.
I have tried many different firmwares but they all seem to fail on installing the new bootloader. I can always recover back to Android 9 using a collection of files called AP_G955FXXUCDUD1_CL21427293_QB39365969_REV00_user_low_ship_meta_OS9.tar.md5
Can anyone point me in the right direction for a ROM running android 8 or 7 that I can root.
Essentially I do not care if it is stock rom as long as I can root the device. I have successfully rooted my devices running android 9 using magisk but the essence is that I need to run android 8 or 7 and being able to use google chrome as a browser.
Any help is much appreciated
Best regards,
Erik

So I downloaded the zip file and unpacked it in hopes of finding files compatible with Odin. But they were not. So what I did was install my android 9 OS that I found that was working and then rooted it using TWRP and Magisk, which is quite simple.

Hi,
1) Download the .zip file of the light ROM : https://forum.xda-developers.com/t/s8-s8-nougat-01-jan-2020-v30-lightrom.3636154/
Then magisk.zip, search it on the internet.
2) Flash the ROM via a custom recovery
3) Then flash magisk.zip
4) Reboot
It will work for sure with Nougat or Oreo, with any Binary number.
You can downgrade with a custom ROM, not stock.
Lastly don't use Odin but a custom recovery !

Thank you so much!
I will try that. I had found an older phone lying around running stock Oreo, that I rooted.

General For all people who encounter problems (bricked smartphone, ...)

Personally, what I did on my RMX3363 EUEX version (Orange France network) :
- I bought it under RUI2 then did an OTA update on RUI3 C08
- then I unlocked the bootloader (with Deeptest RUI3) and root the boot (with Magisk)
- then I installed LOS recovery 19 and LOS 19
- I kept this configuration for several months
- when I decided to switch to LOS 20 (so RUI4), I did a wipe then tried to install LOS recovery 20 but I met a bootloop on the bootloader
- I decided to flash the IMG files (merged super files included) extracted from the C13 firmware (so RUI3) because my stock base firmware was C08 and Realme officially reports to be under the C13 before switching to F06 (stable version of RUI4, the previous F0X being betas)
- under the C13 stock ROM, I did an OTA update on RUI4 F06
- then I installed LOS recovery 20 and LOS 20
- to finish, I rerooted the boot (with Magisk) via adb sideload
So my humble and modest experience is to make sure you do the RUI version upgrade while on a stock ROM, then go back to a corresponding custom ROM if you want. This is easily understandable as custom ROMs do not modify the stock base firmware (from "A" to "C" and then "F" for our RMX3363) but only adapt to it (that's why there is no LineageOS version EU or RU or IN for example).
If that helps.
For me works like a charm!
