Hello! Please help. I have a new samsung galaxy tab s4 t835 sm android 10. One ui 2.1. I have decided to get root rights via twrp. I have done everything following instruction. Unlocked boot loader. Frb open. Switched tablet to boot mode, installed twrp in ap via odin.Immediately rebooted and trying to get into twrp. Appears at the top of the inscription ....recovery. And at the bottom there is an open lock and it says custom. After reset restored stock recovers . I tried again and flashed the kernel with the custom patch and it did the same but with the kernel writing on the top and also the padlock with the custom inscription. I had to reflash the new firmware. Why can't I log into twrp?

*******************

Здравствуйте! Помогите пожалуйста. У меня новый samsung galaxy tab s4 t835 sm android 10. One ui 2.1. Я решил получить рут права через twrp. Делал все по инструкции. Разблокировал загрузчик. Frb открыто. Перевел планшет в режим загрузки.,установил twrp в ap через odin.Сразу перезагружаюсь и пытаюсь попасть в twrp. Появляется сверху надпись ....recovery. точно не помню. А снизу открытый замок и надпись custom. После сброса восстанавил стоковое рекавери . Попытался еще раз и прошил ядро кастомным патчем и тоже самое только напись сверху kernel и тоже замок с надписью custom. Пришлось перепрошивать новую прошивку. Почему не заходит в twrp?

also seeking help ;)

I have a samsung galaxy tab s4 T835LTE android 10. One ui 2.1

I can't find a download of twrp for GTS4LLTE seems only GTS4LWIFI is available :(

can anyone link me or post the location for download ?

TIA :)

nvermind tried USB2 port and it works fine :)

and I used the wifi twrp and it worked fine :)
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] stalker780:
Did not work for me either. Stock T835CZHS5CVD1.

I always get a bootloop on step 9.

However I can enter TWRP with volup.

Struggling to root my device with latest stock for 2 days already. No luck so far :(

I also have T835C. It is a Hon-Kong version. Basically, an only difference from T835 is in preinstalled bloatware.

UPD:

How to Patch Samsung AP Firmware via Magisk

In this guide, we will show you how to patch the Samsung AP Firmware file via Magisk Manager and get the magisk_patched.tar file.

www.droidwin.com

Rooted my tablet by patching stock AP with Magisk app.

After flashing patched and deciphered AP I could install TWRP + Disable_Dm-Verity_ForceEncrypt_11.02.2020.zip with no issues.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Phil21185:
Risky crosspost with the main Magisk thread, but might be more relevant here.

2nd Tab S4 in the household. First one (wifi) patched fine many months ago and happily running Magisk ever since. I'll also mention that I root any new device in the house almost straightaway, so am pretty familiar with the process in general. I can follow instructions but don't necessarily know what it all means, if that makes sense!

This one (bought for the OTHER child...) is an LTE so a T835 and I cannot get Magisk flashed without the device then entering a bootloop.

I have tried all recommended methods online that I can find, including Manual Boot image patching with Magisk 25.2, and installing TWRP, DM Verity Patch and Magisk 22.1 (latest I can find as a zip, I have also tried renaming the later version apk files to. .zip). Running A10, so no WETA kernel (not that I can find the correct one now, all links are to Mega and have been taken down),

Either way results in a bootloop. I reflash stock to resolve. I can boot stock without issue.

Would greatly appreciate any suggestions.

T835 / Tab S4 LTE

Bootloader is unlocked (as I say, I can flash, but not boot).

Stock A10 firmware from Frija (March 2022 security update)

TWRP 3.6.2 (when trying that method, also tried with 3.4 - 3.2.3 [found on my computer from the first Tab S4 rooting] will not boot to recovery)

Magisk 22.1 zip if trying TWRP method

DM Verity patch from 5.21.19 for TWRP method

Magisk 25.2 for boot image patching method.

Thanks.

EDIT: Finsding that revision 5 firmware files are not liking magisk.

Currenlty patching the March 2021 version (as I cant downgrade now) and will report back.

EDIT: Well, 45 minutes of adb pull later and no dice. Earliest R5 bootloops like the others. Entering recovery and factory resetting after flashing Magisk doesn't help either.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] adeelsmatrix:
(First of all, I'm not aware of revision 4 and 5 builds)

I've SM-T835-LTE and I'm on A10 One UI 2.1, build number QP1A,190711.020.T835DXU5CVG2, security patch 1 June 2022.

These are the steps I've taken to make TWRP and Magik work:

1. Unlocked the Bootloader (Just enable OEM Unlock in Developer Option, this will unlock the bootloader).

2. After restarting, I downloaded the stock firmware for my region (XME) CSC : T835OLM5CVG2 using Frija-v1.4.4.

3. Extracted the downloaded StockRom.zip to patch the AP file using Magisk. (I've used my Oneplus 7T running Magisk v23.0 for this purpose)

4. After patching the AP file, I used (Odin3 v3.14.1_3B_PatcheD) to flash all the files BL, Patched-AP, CP, CSC.

5. Tab auto restarted and shows the Magisk app in the app drawer. I didn't click on the app.

6. Turned off the Tab and started in Download Mode.

7. I installed the TWRP twrp-3.6.2_9-0-gts4lwifi.img.tar with (Odin3 v3.14.1_3B_PatcheD) using AP.

8. Tab auto rebooted, swiftly pressed the Vol-UP button to reboot in Recovery Mode.

9. Did Format Data and Wipe Cache/Dalvik using in TWRP.

9. Put Disable_Dm-Verity_ForceEncrypt_11.02.2020.zip file in the storage using TWRP-MTP and installed it.

10. Restarted to the system in TWRP, Tab took 5 mins for the first boot.

11. Installed the Magisk app that is already showing in the App Drawer.

I've done all this on my Lenovo ThinkStation P710 using a USB 3.0 front port.

Magisk SafetyNet FAILED but everything else is perfectly working.

Hope it helps.

PEACE...✌️

I also have a T835 LTE version and I am curious about tablet functionality after flashing with GTS4LWIFI since I can't find dedicated LTE version.

Here is software information from my tablet, can anyone tell me does screen rotating works afterwards? I have read this thread from first post and got impression that I can get it portrait or landscape oriented. Does it mean if I choose portrait I can't watch YouTube videos in full screen landscape oriented any more?

Also did someone build kali nethunter kernel for this device running android 10?

I have never rooted android before and I'm afraid things may go wrong so any help would be appreciated.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] oh00:
links are dead. i cant find anywhere to download them
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] SpaghettiCat:
I'm going to make a proper post about it and mirror these files later, but, in short, you can find the files here on 4pda .
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] SpaghettiCat:
Excellent guide, and thank you very much. I'll make a proper writeup soon, but essentially for, what I believe are builds 4 and 5, this is not enough: you will be stuck in a boot loop no matter how closely you follow the guides posted online for S4, including playing around with Forced encryption and vm-verity disablers. After a 30-hour saga rooting this tablet I found the solution! One MUST flash the WETA kernel! Flashing Magisk-patched AP or flashing the older Magisk .zip somehow is not able to boot in the latest official S4 firmware it seems.

Here is a great guide that includes flashing the WETA kernel.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] speed_boy:
Btw, brightness is not working in twrp.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
Flash as boot? What are you talking about? TWRP gets flashed to recovery.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] speed_boy:
Sh##. My fault. You was talking about kernel and then this message.

So anyway. Plz fix your manual because it is quite unclear how to flash kernel.

Tablet reboot ok
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
You need to connect to internet, I know that much. The device will call back to Samsung servers.

I did have one instance where it took a few minutes before it showed up. I would flash the whole firmware though, is there a reason why you didn't?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] enotar:
Well I thought it was not necesary as I already had Pie plus I am traveling so trying to save some time.

But no I dit not connect to internet.

I will try tomorrow morning.

Thank you
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
Ah, already in pie then your fine.

It will be the not connecting to internet. You need to connect to WiFi somewhere and let it register
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] enotar:
Ok Ill try then and advise.

Thank you

---------- Post added at 07:17 PM ---------- Previous post was at 06:31 PM ----------

one more question:

Why connect the tablet to internet? When you go in Download mode the tablet doesn't recognize wifi or I am wrong.

And my computer is connected to internet so on this cas that should be something else.

Not sure...
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
Because the tablet boots, connects to internet, checks Samsung servers, disables the KG/RMM lock. This then enables the oem switch to be present in dev settings. This is all system and kernel stuff. With no switch present, it will trip KG/RMM causing an instance of needing to full wipe and flash back to stock. It's to protect an owner from theft of device and sensitive data.

That's all I know in a crude sense.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] enotar:
Success here so yes internet is needed.

All perfect, I apreciate the help.

Btw: you cannot get in DL mode with touch combination. You need to turn off the tablet press and hold vol up and vol down and connect the usb cable and wait for few seconds.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] gerabbi01:
Please tell me there's a way beyond this screen. Dire straits
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Reuben_skelz92:
You can still get to download mode. Hold power until it turns off. Before it boots up plug in a cable connected to a PC or laptop while holding the volume down button
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] gerabbi01:
Thank you. I've made it to download. My only option is restore to stock firmware? Or?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Reuben_skelz92:
Yeah flash stock through Odin
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] akmandal:
Will this work on the 837P Sprint version?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
Not sure what you mean by touch combination?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
I'm not sure whether you can unlock the bootloader on the sprint version? If you can then yes it will work.

Sofar everything works (1 week use), I also finally got Galaxy Wearable working :)

Updated Magisk aswell, no problemo, except

Bluetooth is buggy (after disconnecting the device is ALWAYS forgotten), but you can get that fixed by downloading libsecure_storage ... by IanmacD on Magisk

You can flash through Odin on this screen aswell. Had this aswell. Though if Odin fails the first time, just try again, but unplug and "restart" beforehand.

I had this about 4 times, 2 times I needed up to 3 attempts without it failing.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] gerabbi01:
Just a quick note of thanks to all who've contributed to this project and the Tab S4. Thank you. I'm back up and running. Actually I was back up on Saturday but wanted to make sure everything was normal. Tab is doing it's job without a hitch. Thanks again.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] enotar:
quick one,

Today I tried to Factory Reset flashing last firmware with Odin.

I wanted to check Secure Folder

All went well but Secure Folder doesn't work and when I launch Samsung Pass it says surprisingly "Your device has been rooted! Samsung pass cannot be used on rooted devices for security reasons"

I am not sure I understand why if I flashed firmware with Odin 3 files (BL, AP, CSC but not Home CSC), that should bring all to factory + I check with some tools and these says that it is not rooted.

I flashed twice same result. Is there no turning back, I dont think so.

I even set back OEM to lock but no changes

Any idea?

Thank you

Once knox is triggered it will be like that
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] enotar:
Knox has nothing to do with root or unroot if I am not mistaken. This is only trigger when flashing TWRP.

KNOX Counter and Warranty?

You should have a good idea of the relationship between these two when you see the sign, KNOX WARRANTY VOID: 0×0. That means, yes, your warranty will be voided immediately when the Knox Counter is flagged/tripped.

Usually, there are two factors to take into consideration when it comes to warranty claims. One is ROOT status. The other is this KNOX Counter/Binary Counter.

As to the ROOT status, as long as you remove your root in a traceless manner, it wouldn't be a problem.

As to KNOX counter, once it is flagged/tripped (as in "KNOX WARRANTY VOID: 0×1"), you lose your warranty immediately. And more, any benefit this KNOX Tech provides you is compromised and no longer available.

How does this KNOX Counter work? Under what circumstances will KNOX Counter be flagged or tripped?

The KNOX Counter WILL NOT be flagged or tripped when using Samsung Kies or Odin to flash a stock ROM.

The KNOX Counter WILL BE flagged or tripped when you flash a third-party Recovery (like CWM/TWRP) or custom ROM

EDIT: Update, I think I triggered something irreversible

RPMB FUSE BLOWN - RPMB PROVISIONED

Device is not recognized

Now I can flash anything else than stock...…

No unsecure flashing so no more TWRP

Really??????
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
Or modifying a stock boot.img and booting, which is exactly what rooting does.

Actually simply unlocking the bootloader trips knox. You don't even have to flash anything

Knox status comes from a physical "fuse" or fuse like component on the device that blows. Once it's gone, it's gone.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] enotar:
Well OK but now I am stuck with no rooted stock. Happy that it is not bricked and this is warning. I am not sure to try to go back to Oreo and maybe upgrade, there is a new stock available. I don't know why but my device is not recognize with OEM unlocked. Only on locked bootloader.

It should be a second stage security trap after flashing a few times.

Not sure.....

I think I triggered something irreversible

RPMB FUSE BLOWN - RPMB PROVISIONED

Device is not recognized

Now I can flash anything else than stock...…

No unsecure flashing so no more TWRP

Well see in the next few days I will try some stuff.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
Are you new to flashing this device? Or Samsung in particular? And what device do you have specifically? Sorry if you've mentioned all this already

Once on stock, boot up, connect to the internet. Check that oem unlock is present in Dev settings.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] enotar:
No I am not new to flash and to flash Samsung and all this is done but no luck so far. SM-T830.I succeed a few time before with this device but after unrooting and relocking to go back to stock something happend that block unsecure flash.

I will retry.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
Following the instructions in post #2 is essential to boot with any custom binaries.

https://xdaforums.com/showthread.php?p=79483624

Are you following this?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] enotar:
It just stop in setup connection in Odin following the steps when flashing TWRP

What I find out is that when going in DL mode with Odin internet connection doesn't stick
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
Odin can be finicky. There really is no rhyme or reason sometimes it flashes sometimes it doesn't. Here's what I do when I get flashing problems.

I have two versions of Odin 3.13 and 3.12 both will work whenever they feel like it so I swap between them.

If everything is failing I reboot the PC and the device, once there is one failure, you have to do this anyway usually.

Try flashing an older bootloader by itself first or just flashing one you have, let it flash, reboot to download again then try. This is how I've gotten stock firmware to flash when it fails. Flashing the bootloader by itself first, then the firmware.

I dont know if any of this will help you, but really, there isn't anything wrong or different with your device. Usually if there is a message in Odin saying with an error, it's related to oem unlock not being active. You could also possibly be stuck in a 7 day jail of some sort
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] enotar:
Thanks I appreciate, I usually dont have issues and I flashed a lot of devices

What makes me bother is that I got a message when all this start rebooting it says only that An unauthorized firmware has been flashed and device is locked.

I tried changing odin no luck

BTW: Bootloader or TWRP flash in AP if I am not wrong?

I will share my DL screen
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
There is nothing out of the ordinary there. You should be set to flash custom firmware. As long as you go through the steps in post #2.

You just need to finangle Odin to cooperate

Can we still use Dex?

I am now having second thoughts about flashing my device and tripping knox. I always root and flash Magisk in order to mount encrypted volumes/drives using EDS. However, theoretically, I may be able to use LinuxOnDex to do this (still have to buy an OTG hub with passthrough charging).

Will Samsung block access to Dex if knox is tripped? My suspicion comes from reading this in Wikipedia, "Since Knox 3.3 the options to manage Samsung DeX were added to allow or restrict access using the Knox platform for added control and security". --- My fear is that similar to Secure Folders, I won't be able to use Dex.

Can someone confirm whether Dex/LoD works after flashing?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
dex still works., And Linux on dex also.

Though once tripped it's tripped, if Samsung decide to change that, then we'd be screwed in that respect.
