Not sure where I went wrong (device keeps on rebooting) but these are the steps I followed for SM-T830:

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

6. Flash WETA Kernel (Recovery) then Encrypt disabler

7. Reboot to system <-- Device stuck on first logo and reboots every 10 seconds

Thank you in advance for your help! :)

Edit1: Tried to boot into recovery but instead it actually went to Samsung logo (will wait 5 mins and see/reboot to see if it works)

Edit2: It booted to system after waiting for 5 minutes at the logo

Does TWRP stick after you boot to system? I powered off my device and tried to go to TWRP to flash magisk but it just won't go there, it keeps on going to system. Unless the combo key changed? I tried Power + Vol Up numerous times. Doesn't even go to stock recovery :P

Edit: Flashed TWRP again..

1) First boot to TWRP

2) Flashed Encrypt disabler

3) Format data

4) Reboot to Recovery

5) Flashed WETA Kernel (Recovery)

6) Flashed Magisk

7) Power off

8) Turned device on and waited 5 minutes, followed the initial setup

9) Installed Magisk Manager to see if device is Rooted - Not Rooted

10) Powered off and pressed the Power + Vol Up to reboot to recovery (Does not boot to recovery, always boots to system).

Sorry but i need to ask, have you updated to Android 10? as this new update wil only work for 10
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] veekay:
Be sure you are flashing the weta kernel to the boot partition. If you flash it to recovery that would wipe out twrp

hi

I downloaded android 10 folder from this link and used below instructions

after device booted I found that device not rooted

what should I do
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] gechu:
I can confirm that the instructions worked well for Android 10!

Unfortunately I had to revert back to a standard setup because I rely on Google Family Link for managing the tablet and once you enable Google Family Link it locks the bootloader. Trying to boot a locked bootloader having custom recovery while have added a Google account to Android triggers Factory Reset Protection (FRP).

I assume the reason Google Family Link locks the bootloader is because it relys on mobile device management capabilities provided by the OS and these require a stock setup for ensuring its integrity.

Too bad Google Family Link has such a nice UI and overall integration into Android. Previously tried Kaspersky but the user experience was nowhere near.

Question, how do you restore twrp backup as I tried but dont boot and after restoring, reboot every 10 seconds? I got only error opening sdd4 read only and error at the end of restore. I did factory reset, wipe all but SD. Format data the second time i tried.

Thank you
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
What did you backup?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] enotar:
I crossed all in TWRP. So everything possible.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] steevou:
Hello,

I can't find the kernel file in the directory (with the kernel link)

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

where can I find the kernel for android 10 ?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
Try now
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] steevou:
Hello

Thank you very much, Mentalmuso.

I have one last question. Since TWRP is it possible to flash kernel.img ?

I thought that it was obligatory to have a ZIP file.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
Yes, flash kernel.img

Hi there

I've recently got Tab S4 which is still on android 9. Which TWRP should I use to root the device?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Sapiens:
Hi Enotar

Could you please tell me how did you solve the problem of not being able to turn the screen on even that the tablet is on? You mention a mix kernel. I downloaded the weta kernel from the link in the original post.

Thanks
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] enotar:
Go into recovery and flash weta kernel img to boot and it is how I sorted out

Good luck

[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Fenderstratocaster87:
Hey, I want to try A10Rom but I can't(im not able...) flash recovery. I'm on stock A9: never mod. When I try to flash " TWRP...3.4.0-6.tar" with Odin failed the operation and on tablet' s display appears "only official released binaries are allowed to be flashed(recovery)".

I tried to follow these notes:

From 9 unlock OEM (Backup Before)

Odin TWRP latest in OP (Untick auto reboot)

Reboot in Recovery not kernel

Format data

Wipe all but SD Card, then Factory reset

Flash Rom

No need to wipe dalvik and cache

Reboot

.

Have I to follow first post? change recovery vers?update A10?

Thnks

Solved
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] b3rsus:
Interesting. I've faced a strange bug: after installing (step by step as mentioned in the instruction) the tablet works only with closed cover of its case. It seems that the sensor has been inverted somehow. And the issue starts after the very first screen locking. Tried to reinstall from stock for several times, but facing the issue for every time. I think the problem is in the custom kernel.

[SOLVED] Sorry, didn't notice the discussion before. Flash kernel IMG from recovery (not ZIP via Odin). That works.

2mentalmuso, it should be great to mention about this way in the instruction. Thanks! And respect for your work!
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] b3rsus:
A bug again. After rebooting the fully set up device it can not load again, reboots after a couple of seconds every time.

UPD: re-flashing kernel and unrooting didn't help. Seems to be a conflict between the stock rom and the kernel.

How about OTAs? Will they be blocked?

I have OEM unlocking unlocked.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] daitalos:
First,you can read post #2 in OP. Make sure BT is unlocked ! (read & here an interesting article about samsung :

Installation | Magisk (topjohnwu.github.io) )

Maybe you need & "encryption disabler" ! . Also, check if you have the latest BT etc..

It is a good idea, to temporarily remove the "samsung & google" accounts before you start ...

Hi, can you make a new custom kernel for the new T835XXU4CTK1? firmware?

I tried to flash the kernel, it was able to boot, but can't use the power button to turn on the screen... volume buttons dont work. I can turn off the screen though.

EDIT:

sorry, i just realized that i downloaded the old kernel. with the FT5 kernel, the buttons work now.

But can't use facial recognition. (could't open camera. Try again.)

EDIT:

doesn't work, after few reboots, the tablet just keeps rebooting: few seconds on the lockscreen and reboots to the SAMSUNG logo.

any way to switch screen to landscape mode in 3.5?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Ninemeister:
Greetings!

I have a T835N (LTE Korean version) running Android 9.

I followed all of the OPs steps line by line and have made about six or seven attempts. The device is unlocked and gives the impression that every step completed with no hiccups or errors whatsoever, but still does not have root when I check the status.

The files I used were:

Disable_Dm-Verify_ForceEncrypt_05.21.2019.zip

Magisk-v21.4.zip

WETA_Kernel_T83x_5.0.zip

Is the T835N an exception to this root procedure?

Thank you!
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] masster64:
@Mentalmuso

I'm being told by @SkandaH that the build my tablet is currently on (T835XXU5CUE2) comes with bootloader version v5. However, he said it is still possible to create an unofficial compatible TWRP build based on a pre-built stock kernel. Could you help me out, please? See the screenshots.

Detailed issue here

Spoiler content hidden.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] catharsis724:
I'm on this same build and latest official TWRP just worked fine for me. However flashing latest WETA (TF5) gets me in a bootloop. If you want to have root, you'll have to settle for the disable-encryption zip and magisk zip flash.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] catharsis724:
Have you tried a newer Magisk version?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Ninemeister:
I did and i believe that made it work!

The only downside I experience is I cannot hold down the power button to turn the device off. It only powers the screen off and on. The power button wakes the device up and powers on the screen, but all long-hold functionality is gone.

That also has the side effect of not being able to hold Volume Down + Power Button to enter Recovery Mode.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] catharsis724:
VolDown+Power turns off the device, or at the least, it allows for a proper restart.

After the screen turns off and the device is powered down using VolDown+power, then you have to quickly switch to VolUp+Power to enter recovery. On stock, that takes you to Download mode. If you've flashed TWRP, then it takes you to TWRP.

Hi, I'm having the same issue:

I've tried flashing 'TWRP_T83x_3.4.0-6.tar' and 'twrp-3.6.0_9-0-gts4lwifi.img.tar' on my T830 wifi, tried several ODIN versions, they all fail.

The tablet is OEM unlocked.

How did you get it to flash?

Running Android 10 with latest firmware.

Thanks
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] catharsis724:
What do you mean by fail?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] shpitz461:
"Failed 1", see screenshot...

I tried a different PC, tried USB2.0, ODIN refuses to flash TWRP.

The tablet came with latest T830XXU5CUE2 firmware.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] catharsis724:
Could you try this Odin version ?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] shpitz461:
Wow @catharsis724, you da man!

via a USB 2.0 port on a Windows7 laptop.

Thanks much!
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] catharsis724:
NP. Odin versions get upgraded for newer OSes (i.e. A10). Your firmware/build is A10.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Raxcental:
I'm having the same issue as him. "All threads completed (succeed 0/ failed 1)"

I'm already using the same version of odin that you supplied. Bootloader is unlocked. I'm not sure what to do from here. I've tried latest TWRP tar files as well. :/
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] shpitz461:
USB2.0 or USB3.0?

I flashed via USB2.0 on Windows 7, so try USB2.0 port 1st.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Raxcental:
Finally got back around to this. I've tried both 3.0 and 2.0. Always results the same. It's just not working. At this point I'm not sure what to do. I guess I'll just put some info in here maybe it'll help someone help me?

[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] mghtymse007:
Status?

I'm having the exact same issue. i have the SM-T820 too (w/same SW and settings as you have). i also have tried all what you've tried...plus a couple factory resets by relocking and unlocking the BL.

1. Now, the Download BL screen no longer has the status text in upper left of screen, and no matter what I try i cannot get TWRP to flash successfully, nor get the text to reappear.

2. Odin sees Tablet and assigns the COM as usual...untick autoboot....tick AP....add tar....but each Each attempt ends with:

_____

'''

Initialization...

All threads completed (successful, 0 failed 1)

_____

3. Also when the factory recovery loads now, at bottom of screen this text appears:

#reboot recovery cause [unknown]

API: 3

manual mode 1.0.0

Any luck?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Raxcental:
Mine is the exact same situation. No status upper left of download screen. reboot recovery cause unknown manual mode 1.0.0 api: 3. Hopefully somebody knows what to do
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] mghtymse007:
i am going thru the recovery logs seeing if i can see where its getting hung up...

i did notice:

boot_recovery, is_boot_recovery[1]

(possibly looks like a copy [?], or a backup OEM recovery.image has been enabled/created?)

did you try ODIN 3.14.4?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Raxcental:
Yeah. 3.14.4 is the one I've been using
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] mghtymse007:
got a few things going again:

tablet off

plug usb cable in to booted computer

hold vol up/down

plug usb cable into tablet while holding vol buttons

tablet will boot into the correct DL mode splash page with text in upper left.

tried flashing from ODIN 3.13 and it did succeed!!!! however, once i held the voldown + pwr to reboot and then @ black screen hold Volup + Pwr to enter recovery....

it failed!!

now the boot screen has the padlock unlock symbol just above "powered by android" and at the top, left yellow text "Set Warranty: Recovery" (*typing this from memory, so actual words may vary) and is stuck now on boot page.

Only way i found to get the tablet booted after the last flash attempt:

hold all three buttons, release power at boot page, hold volup +voldown until long vibration occurs.

Now.....padlock is gone, yellow text is gone and the tablet boots fine.

i'll do more when home.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Raxcental:
Managed to get the proper recovery screen. Odin still fails for me.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] mghtymse007:
Yeah, I got that screen to reset too.

However, even though the flash is successful every time I try it...regardless of SPFT version....the screen ends up like pic 1. The tablet is completely useless at this point. Only way to get past, is hard shut down and quickly booting with both up/down held until long vibration and screen moves on.

Has anyone seen or dealt with this?? I'm hearing that I need to reflash stock FW...is this correct?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] mghtymse007:
Got it.

Use SPFT 3.13

TWRP 3.3.0

sh progress....
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] mghtymse007:
Spent some time with upgrading to latest TWRP 3.6.0. Reviewed error logs on both systems. Got a few things for you to try...

(Notes: You should be using SAMFW 1.5.65.0, not 1.7.48.

Home | Official Samsung Support US

Get the latest owner's manuals, firmware and software updates for you Samsung devices in one easy-to-navigate location: the Manuals & Software page

www.samsung.com

Use ODIN 3.13.3-1

Before you begin, do a clean reinstall of the Samsung drivers, and reboot....regardless of version previously used.

Do not unplug tablet until all steps completed. Use USB 2.0 if avail, (if 3.0, enter bios and temp change to legacy)

1. When in DL mode, DON'T untick Autoboot....but be sure to keep finger on volup button when you hit start.

2. Flash TWRP tar first.....not vbmeta.tar

3. Tablet will reboot. Once screen goes black....hold volup

4. Tablet may display "custom ROM warning page". Release volup key, hit pwr to continue and IMMEDIATELY press and hold volup again

5. Tablet reboots to page in my previous post with padlock and "CUSTOM" text

6. Return to Odin, now add vbmeta.tar in AP. Do NOT untick Autoboot. Flash.

7. Tablet will quickly reboot. Get ready to Repeat step 3 and 4,

8. TWRP 3.6.0_9.0 should load after second step 4 volup button hold

Hops this helps!

Disclaimer: just my experience to share, I'm not responsible for any damage you do to your device, including bricking it :)

FYI, how I got from latest stock (photo attached, sorry for russian names) to TWRP installed on T835C (Chinese version).

Tools: SAMSUNG_USB_Driver_for_Mobile_Phones_ver_1.5.65.0.exe (not 1.7.48); ODIN 3.13.3; twrp-3.6.0_9-0-gts4lwifi.img.tar; Disable_Dm-Verity_ForceEncrypt_11.02.2020.zip; Magisk-v24.1.zip

Read before starting.

1) Phone in Download Mode, flash twrp-3.6.0_9-0 as AP. DON'T untick Autoboot

2) Keep finger on volup button, when you hit start in Odin and move eyes on tablet ASAP.

3) Tablet will reboot at the end of flash. Once screen goes black....hold volup

4) Tablet will start and show something (boot screen), keep holding volup

5) When TWRP loading screen is shown or TWRP is opened, release volup

6) Format Data (Wipe did not work), Wipe Cache/Dalvik.

7) I flashed Disable_Dm-Verity_ForceEncrypt_11.02.2020.zip (in TWRP)

8) I flashed Magisk-v24.1.zip (in TWRP)

9) Rebooted to system and waited for a while on the boot screen.

p.s. I did not use vbmeta.tar (I tried it as AP, yet it failed).
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] mghtymse007:
Interesting....did you flash WETA...? If so, at what point...
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] occupat:
I did not.

The reason is that I just was not able to:

* the #2 post implies that WETA needs to be flashed via TWRP, give a link to WETA on Mega, where new one (Date added) is "WETA_Kernel_T83x-TF5.img".

* while I do not know how to flash *.img via TWRP (and was too lazy to look for a way to convert, if any)... I also did not want to download "WETA_Kernel_T83x_5.0.zip" because is dated back to 2019.

I was willing to brick my device so I did what I had and was able to. Photo of my current (rooted) boot screen is attached.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] mghtymse007:
Ya, I did a model ROM/HW comparison.....Big differences in these two model's FW and build structure. Plus a lot has changed since their release!!

Unfortunately for us, I've noticed this and most of the older threads much quieter lately. The newest models seems to be where everyone's at. Which makes senses considering the recent bad news with magisk, and the challenges we face with the new releases and the battle for root.

Good job on getting it done. Seen many "shiny bricks" since i started. Not easy using tips, threads and mods from 3 yrs ago. Nice to see that you have a boot screen w/o the red text warning. Do you still get the Samsung warning " about to boot a modified ROM" just before this page...(which requires either a pwr button press, or a few sec wait to continue the boot)?

Thx...MM007

Hello everybody. I've been trying to install twrp for days and I'm not getting it. When trying to flash the auth error. appears on the screen on the tablet the information that it is only possible to install the official binary. From what I've read, the problem occurs because of the RMM STATUS: Prenormal. I've already tried to do the procedure of waiting the 7 days and still the status does not change and I remain unable to install TWRP or root the device. Has anyone managed to do the procedure in the last few days and was it successful? How did you proceed? I'm already losing hope of being able to solve the problem. PS: Forgive me for my bad english.
