I have flashed LineageOS on my old Samsung Galaxy S6 phone and I like it a lot. But I want this ROM on my Tablet and I want everything to be working.

WiFi
Bluetooth
Front Camera
Back Camera
Software Buttons (Apps, Home, Back)
Volume Buttons
Power Button
Sound
Etc

I could not find any official builds nor any unofficial builds of LineageOS for this device. Has anyone successfully flashed this ROM on the Tab S4 without GAPPS and it works like a charm? I have the SM-T830 model.

Hi Mate, I am looking for the same thing. Have you had any success?

I have not tried it yet since it is an expensive tablet and I do not want to screw it up. I did more research and I heard it can be buggy with LineageOS :(

I plan on flashing my phone this fall when my contract expires and I could care less if it bricks my phone then but I want my tablet to last at least 5 years and I would like my tablet to be De-Googled with LineageOS and no GAPPs.

Hi mate,
I've been playing with this tablet for a while and I thing I have messed it up in every different way you can imagine. At one point with Odin I even flashed the BL bit to the AP and AP to BL. There I thought that's it, it didn't even bring up TWRP or anything after that. With the button combination you can get to download mode if the USB is plugged in. I believe there is no way you can overwrite the "download-mode" bit so you can get in there always, no matter what you do. This meant that I could flash the original stock stuff back onto the tablet. So don't worry, you cant mess it up.

Hoping to get mine this week - I know you can flash any Treble based image, but will the Spen still work on other roms?

No luck so far getting anything to boot - just gets stuck on the logo

Hey, Thanks for this I installed it and ran it for about a day and it was pretty cool and worked . However it is unstable and is pretty much a ticking time bomb and I cannot recommend this to anybody wanting a stable ROM for their Tab S4. If you're looking for a good stable ROM go check out WETA it has great modifications and is kept up to date. That being said these are the following problems I had using this GSI.

List of things broken or not working
- Screen Locks (Any Pin,Pattern or Password will cause the UI to bootloop)
- Speakers (Only two of the four speakers will work causing audio to be low.)
- Root Access (Root only worked for a select set of apps.)
- Digital Wellbeing
- Unable to fully complete setup. (I.E Android Setup will often crash)
- Incorrect Battery Levels Shown
Im sure there are other things that do not work but these are what I primarily experienced.

Part of the problem of not having anyone who is willing to develop a custom rom for this device - being stuck with crappy stock samsung.

I have wondered if there would be enough interest to warrant setting up a pool for a developer to get something fully working - I'd certainly be willing to donate.

Agreed, I would be willing to donate a bit as well. Saddens me to see LOS for the S3 and S5e but not for the S4. Hopefully one day that will change.

I tried installing LineageOS 16 and 17 using arm64-a, but I always end with bootloop. There is some extra step I must do?

For now I done:
- Installing latest firmware version
- Installing TWRP
- Installing image.
- Format Data + Factory Reset.

Thanks!

    (after format data,try to flash "DM-VERITY - FORCEENCRYPT DISABLER" + Magisk - remove accounts google & samsung before beginning)

    I'm not sure if it will work on android 10 gsi rom, just try it...
    Even if it works, many things may not work on this device. There will definitely be many errors... Gl

    Thanks! Yeah, seems like my failure was related to encryption. GSI really dislikes encryption on our S4 Tab, you can't even set a screenlock, as an exception happens from the CryptoProvider.
