Even if the usb cable plugged, I'm not able to go either in download or recovery mode. I tried vol down+ power, vol up+power and even vol up+down+power.

Whatever I'm trying, I go back to Security error screen unfortunately.

[MENTION=4983954]Huntyz[/MENTION]: Did you manage to go to download mode?

Edit: I was finally able to go in DL mode. Don't know exactly what I did, sorry.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] airmaxx23:
Just turn the tablet off without having it plugged in, then hold down volume up and volume down together and plug in the USB cable. You'll immediately enter Download Mode.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Kholargol:
Thanks! If I want to restart directly from DL mode to recovery mode? I've unticked reboot option in Odin and flashed the TWRP tar. I would go to Recovery mode as recommended, without system reboot in between?

It's the 2nd time I'm flashing back my tab to stock because of this, I went straight to regular reboot (I didn't find this proc anywhere)
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Huntyz:
Yeah it took a few tries but I got into download mode then Odin failed a flash which gave me a "software did not update properly" but managed to flash stock Pie again and am on weta 4.1
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Kholargol:
And how did you proceed for step 3? "Don't let it boot to system, boot straight into TWRP"
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Huntyz:
Hold power and vol up buttons
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Kholargol:
It didn't work for me. Here how I proceed for those who had the same problem:

- Power + vol down: it restarted the tab

- immediately after: power+vol up
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
Then you're doing it wrong, keep trying.

Press and hold vol down and power for 9-10secomds, then swap to vol up and power. And keep holding
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Kholargol:
I've tried 3 times a row and and got the lock message each time..

This part is unclear. I flashed AP.tar and was able to boot without lock message. Then I started the tab in recovery mode in order to flash your rom but the recovery was restored to standard Samsung one. When I say "This part is unclear. ", I only mean that I don't understand what should be the expected result of this operation: to fix the lock message or to come back to stock?

Still don't know if I must resign or not :(
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
Both. You need to flash back to stock to remove a lockout.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Kholargol:
I'm confused, sorry.

Does it means that I won't be able to install to install TWRP anyway? Or does it means that once I've flashed the stock AP.TAR I must repeat all the previous operation starting from step 3. (flash WETA_Pie_T83x_Root+TWRP.tar)?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
To unlock bootloader, you need to be on stock firmware, connected to Internet, and go to dev settings and make sure the oem unlocking switch is on. If you are locked out via binaries, then you need to flash stock and start over.

Once you have that, then follow the instructions to flash TWRP, then the rom.

TWRP

reboot twrp

Format data

Flash encryption disabler

Reboot twrp

Flash rom.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Kholargol:
I already started over after going back to stock, but it leads me to this infinite loop:

1. From stock + OEM unlocked with Internet on

2. Flash TWRP + fix

3. Get lockout message

4. Flash stock

5. Goto 1.

I will try tomorrow different things. If I succeed, I will write the detailed process. I know I'm not alone as people write me in PM to ask me if I managed to install the ROM!
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Huntyz:
Seeing as your beer fund link works now i donated $10 Mentalmuso thanks for all the work :D

---------- Post added at 05:40 PM ---------- Previous post was at 05:39 PM ----------

You need to boot to TWRP right after flashing TWRP and dont let it try and boot the system as said previous :

Flash TWRP

reboot twrp

Format data

Flash encryption disabler

Reboot twrp

Flash rom.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Kholargol:
But, I do, I promise! Here are my exact steps:

1. Flash complete stock PIE using Odin (BL+AP+CSC) with automatic reboot on

2. Now, in full stock, I boot up fully, connect to internet and open check oem unlock is. Switch off the tab.

3. Switch on tab into download mode. Deactivate automatic reboot in Odin. Flash WETA_Pie_T83x_Root+TWRP.tar in Odin. Still in Odin, I reboot directly into TWRP.

4. TWRP is installed, I flash directly T83x_PIE_encryptdisabler_+++.zip then I format data

5. Reboot to recovery/TWRP

6. Reboot to system : Everything is fine

7. Reboot to system: Lock device message appears
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Huntyz:
Then did you connect to internet and check OEM Unlock again before rebooting?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Kholargol:
No, I didn't indeed. Because I wanted to follow instructions brainlessly in order not to make mistake and it was not in the proc. Also, OEM stay unlocked from the first time I switched on, event after coming back to stock so I didn't come in my mind to look at it again.

Will check it next time, thanks..
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Huntyz:
Yeah i think you always gotta check its enabled in options to make it enable again?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] #Teampixel:
So is TWRP and root on pie a no go ATM ?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] ariveraiv:
Everything seems pretty straight forward. The process is clear. But for some reason when I try to flash twrp it always hangs, stays stuck on analyzing file. But the same Odin can flash me back to stock with no problems. I also have a patched Odin that I use to flash the t-mobile firmware on my sprint tab s4 t837p. Stop my problem is getting twrp on the device. Not sure why if stays stuck.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Kholargol:
Finally managed to install the ROM!

What I did is, instead of rebooting to system at the end (and get potentially the lockout message), I switched the tab off and went to TWRP to flash the ROM. Thanks for your help (and patience!)

Hi,

Got an error 15001 while trying to launch Netflix app.

I'm able to install Netflix app from the store and I've hided to root it in Magisk and also installed Netflix enabler V3 module but the error remains.

I've also try to sideload app from apk mirror, same result.

(my device is set to network time)
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] EggZenBeanz:
You need to get the liboemcryoto module from magisk. Download, install and reboot. Netflix still needs to magisk hide too.

It worked thanks. Everything is working as expected now, it's perfect.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] EggZenBeanz:
Use the T837 in the downloads folder. Works for my T835. Although I've not checked the phone app, as reportedly it's not in the ROM at install. It's possible to get from APK Mirror, but I've not tried this yet. Other than that it's a sweet ROM.

Apologies for putting this here as well as on your Telegram. I'm just stuck. I have an sm-t835 and I have a stock Malaysian PIE rom. I successfully unlocked the bootloader. However, when I tried to flash your WETA_Pie_T83x_Root+TWRP.tar file through Odin AP, it failed. There was a message in Odin (Auth) and on the screen saying that only genuine images can be flashed. Do you need to have the proper authority code in your tar file for it to flash on my t835?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] jack allen:
I love that this rom is for my new tab s4 and there is also a rom for my note 9 aswell so both will be running the same rom thanks for your work

How to root a stock PIE rom on an sm-t835

x

I already OEM unlocked the phone. I have been able to root my PIE rom by getting Magisk Manager to patch boot.img (from the Malaysian stock PIE rom) and flash it again through Odin. I can not install TWRP without the phone recognising it's non-genuine and locking up with a fault. I'm pretty happy I have a rooted PIE rom. I don't know if the patched file would work on ROMs other than the Malaysian stock PIE rom. I'll attach the image that I flashed to AP with Odin3-v3.13.3. So ... these Samsung devices are touchy security wise so try this at your own risk.

To be pretty sure it will work:

1. Make sure your tablet is sm-t835 (international LTE version, mine has 256GB but I don't think the GB matters to the rom. I'm not 100% sure though.)

2. Flash the Malaysian pie rom from here: https://www.sammobile.com/firmwares/galaxy-tab-s4/SM-T835/XME/download/T835DXU2BSD1/266938/

Follow the instructions and use the version of Odin (as quoted above) that sammobile provide. Don't follow their instructions about getting into Download mode. On my device, you power off, then simultaneously press power and volume up until the device vibrates and the screen comes on and then you let go of both fingers. Does Samsung make this different randomly even on the same device?

3. Set up your phone basically, until you can go in to settings and repeatedly hit "Build number" until you are a developer.

4. Activate OEM unlocking in Developer options.

5. Reboot and automatically erase the device

6. Do a basic setup so you can verify that OEM unlocking is now activated. You'll need to hit on "Build number" repeatedly again.

7. Get your device in to Download mode

8. Load the file here in to AP in Odin: https://1drv.ms/u/s!AsF1UT5mNVpthLxcdvS1d0y_Dy7NqQ

9. Flash it.

10. If you get an error, repeat steps 6, 7, 8, 9. I had to do this for some reason

11. Reboot. Setup. Install Magisk Manager latest apk, available here.: https://xdaforums.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445

12. Run Magisk Manager and follow the prompts to set it up fully.

Enjoy your rooted tablet.

Ah ok strange that the malaysian firmware worked and the stock image didnt i wknder why?? Maybe to prevent people "tampering" with thier new tablet as 30mins after i get a new galaxy note or s.... i root it straight away because i know how i want my phone to feel not samsung at the end of the day we are paying for the devices in one way or another so technicly its our property. Well cool for the info ill screen shot it and crack on i literally just want to have viper fx on my tablet as i use it as music player via bluetooth and when your in this part of the tech world you know how good it sound with it on lol, so thanks agian for sharing your work around we all appreciate it.

Viper4Android FX fails and harms wifi with my setup

Viper4Android FX 2.7.1.0 from XDA Labs does not work with my setup. The Magisk module shows as being installed in Magisk Manager. However it is not recognised by the app, even though it has root permission. I removed the module and uninstalled the apk. Then I discovered that I had lost wifi. I re-flashed the Malaysian rom using HOME_CSC_** to keep my data. I needed to power off at the prompt to wipe the device because it failed an integrity check, just prior to getting in to Download mode to install the Magisk patched boot image. I possibly didn't need to reflash because wifi was still not working. I asked the system to forget the credentials of my wifi and re-entered the credentials. I got wifi back. I guess I'll never know if I could have done that rather than re-flashing.

I have Busybox for Android NDK 1.30.1 by osmOsis magisk module working well (checked it out in the terminal). I have GLTools magisk module working, giving me a frames per second counter and graph in the PUBG game.

Superuser (from Magisk) is working well with:

Device info HW

Linux Deploy (you need to the user "root" when you install linux though which is a bit strange)

Solid Explorer

Terminal Emulator

Termux

Titanium Backup

I noticed that SELinuxModeInverter4Magisk-v1.0.6.0(v1900) does nothing ("gentenforce" always returns "Enforcing").

I might post this on the Viper thread too.

Cheers

Run

su -c killall -q audioserver

in a terminal.

Then Viper runs.

After rebooting it runs so you don't need to issue the terminal command again.

Wifi is working.

So I was able to get on stock Pie with root, everything booted fine. I then power off, and when I power back on, I get the unofficial binary error. I then flash Pie and root again, and sem problem after powering off.

Anything I can do that would allow me to power off / power on without the binary error?
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Walker Street:
A second after pressing the power button to turn on, I get a small yellow message "Set warranty bit: kernel". I think this is normal for a rooted ROM with Samsung. If you need to return the tablet to the store, flash the stock rom first. That removes the message (I'm pretty sure).
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Walker Street:
I spoke too soon.

Viper did not recognise the Magisk module again.

I had to run

su -c killall -q audioserver

again.

Then restarting viper worked.

So I think this needs to be incorporated in to the start up of viper so it works every time.

You need to flash custom kernel, and the forced encryption disabler in my download folder. The disabler also removes some apps.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
Why have you posted this? You can't just flash a patched stock boot.img.

You need a custom kernel, with all security disabled and permissive enabled.

This is something I have already provided in my download folder. Flashable in Odin. I did this the day after Pie became available.

Edit . Ok I see you had issues flashing the Tar. I think I mentioned somewhere that an auth error is related to bootloader not liking what is being flashed. Mismatch. I haven't seen any other reports of this

I was able to flash your tar file (I have your kernel and TWRP) but now my internal storage is not readable. My micro SD card died on me. It isn't recognised by the tablet or windows (doesn't even show up in Windows Disk Management). So I can flash the decryptor script. I am trying to access a USB stick through OTG. So far I am failing. Does it need to be FAT32 for TWRP to recognise it.

EDIT: I booted up again and I can now read my internal storage. If I want to flash your rom, I will need an SD card .... true?

There is a separate rom zip for the 835 now.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
Yes, but it's not going to change the base used from t837 to t835, all it will do is add Dex mods

[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] MsDOSghost:
Running a WiFi SM-T830 was on stock PIE image I grabbed from sammobile *XAR* I believe the last four of the build number is (BSD1). Anyways I downloaded the three files from your downloads section for my tm830 version and flashed TWRP package via Odin without issues. Once in TWRP I wiped DATA and I flashed the ROM .zip file that was successful then flashed the the dm-verity package, rebooted into recovery and made sure I could mount storage. Once I booted the tablet it started setting up. However I didn't see the Magisk app anywhere in my app drawer, so I installed Root Checker App and it said I wasn't properly rooted, I tried to install BusyBox and run it and it too said wasn't properly rooted. I installed a different Root Checker App and it actually said I WAS rooted. I remembered I had downloaded Magisk.zip and it was on my SD Card so I rebooted into TWRP recovery and flashed Magisk.zip it said it completed successfully however when rebooting the tablet when it came back up Magisk was no where to be found. Not sure what I did wrong or why the root doesnt seem to complete successfully or why one Root Checker app says I am rooted but then I cant run Busy Box because it says I am not rooted and another Root Checker says I am not lol. Hopefully a simple mistake I made somewhere, please if anyone can offer any guidance or help it's greatly appreciated!!
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] Mentalmuso:
Simply download and install the magisk manager app. The kernel is pre patched. Pie makes it difficult to install user/data apps from twrp.

And what dmverity zip? I don't supply one. You may mean the forced encryption zip?

Edit . Also, there is a new TWRP built by me. There has been a new thread started on xda. Mtp, and otg are working.
[Samsung Galaxy Tab S4 ROMs, Kernels, Recoveries, &] MsDOSghost:
Correct the Forced Encryption Zip. I misspoke on that. Didnt know about the new thread will head over and check it out. Thanks for the reply and all your hard work Mental much appreciated!! I will retry again this evening and check back with results. :fingers-crossed:

[UPDATE] I went back and reflashed everything also using the new TWRP package that you provided in the other thread which works great! Downloaded and installed Magisk Manager and I now have a perfectly working factory PIE image with ROOT and god its so smooth! Thanks again!!!

Hi Mentalmuso and users,

I have to ask out there in user land. Has anyone else installed Weta 4.01 on an sm-t835 and got 10 minute boot times?

I ended up going back to stock but patched with Mentalmuso's kernel and twrp with a rooted French Pie ROM, skipping installing Weta. I tried many times to install it. Always slow boot, sometimes boot-looping after 10 minutes making it more like 20 minutes.

Thanks for all your hard work.
