[ROM][UNOFFICIAL][10] LineageOS 17.1 [T713][T719][T813][T819]

[SirSeanM10Pro]

Still on LineageOS 16 and haven't upgraded for 2 years because I forgot this tablet existed. Are there any benefits to moving to LineageOS 17? On the 21 Aug 2022 version currently

LOS 16 is more polished than LOS 17 on the TAB S2 T813. Things that work on the former that don't on the latter:

• GPS
• Wi-fi direct and wireless displays
• Enforcing SE Linux
• Better Alt-Tab integration when using external keyboard

Things that are better on LOS17 in my opinion:

• Dark mode
• File save dialog in dark mode (in LOS16 the filename appears white on white)
• Wi-fi sharing (Android 10 feature)

I was using LOS17 for a year or more, but decided to switch back to LOS16 and am not regretting it.

I have the T719 with stock Samsung firmware and would like to flash this ROM. Can someone guide me as to how to unlock the bootloader and install TWRP using macOS? Heimdall does not seem to be compatible to current macOS versions

I solved it by running a windows WM with Odin. Flashed with success

I tried to install the latest 17.1 on my T813 and the corresponding open gapps arm64 10.0 but after some time of booting, it always ends up in the recovery again. The same when I force reboot as described in the OP.
Tried the same with 16.0 and open gapps arm64 9.0.
The only way it worked once, was when I didnt install any google package. What can I do? I tried to do everything correct...

I used arm64-10.0-pico-20220215
Worked till today

Probably use pico as mentioned above, and don't forget to reboot to fastboot /recovery to install it right after installing latest 17.1 if it doesn't work if you install it directly after. Anyway, don't let it boot system first.

I installed this rom on my tablet and it tells me that selinux is not active. How can I activate it?

For those interested in a stable and nearly full functional LOS 18.1, I'd suggest taking a look at the builds of retiredtab, https://xdaforums.com/t/unofficial-rom-alpha-lineageos-18-1-for-sm-t813-march-17-2023.4540413/ covering the most issues (selinux, GPS...). Though being labeled as "aplha", I judge the build as stable and worthy giving it a try. I came from this 17.1- build and I am absolutely impressed of the new LOS 18.1 on my T813. In the meantime, I build by myself, thanks to the work of the author of the build, giving the necessary details.
The installation process is quite straight forward. Playstore (Opengapps) works without issues, even Magisk is no problem...I don't like to dig further. Just for info...

I notice new builds of 17.1 appear on wickenberg.nu for gts28velte (T719) but the recent changes are not loading. Can someone confirm whether lte and other issues have been fixed? I have just had enough of being stuck on stock Android 7

Hi all, I am on stock android on my T810 and am looking for latest 17.1 rom (with gnss hwbinder and S2 wifi blobs patches). I am confused by all the model numbers, and threads with over hundred pages. I cannot find a link for the rom, I wonder if it is OK to take the same ROM as the T813?

I did find another thread for 18.1, which seems to be OK for many people, but for me, I am not after latest, I want stability and snappiness. In that regard, is 17.1 better than 18.1?

Thanks.

UPDATE: Nevermind, I don't think there is a 17.1 lineage rom for T810 due to having a different CPU to the T813. The only one available seems to be 18.1 and 19.1. Link for 18.1 is https://xdaforums.com/t/rom-unoffic...0-t715-t715y-t810-t815-t815y.3879302/page-124 It seems it would be more stable than 19.1

UPDATE2: No I take it back, there was once a 17.1 rom, but it has been completely purged from the internet. You can see it being downloaded here

Anyone know where is this rom now?!

I had almost forgot my wife had this tablet (T719 8" LTE), so I was glad when it showed up in a drawer and it actually still booted. Stock ROM is nice but Android 7 is getting too old and where is the fun without a homebrew ROM to try ? I tried both LOS 17.1 and LOS 16 and opted for the latter which feels more polished (SELinux enforced, it passes the safnet test, camera works fine).

Just for confirmation:

both Android 9 and 10 are "abandoned" and will not receive further security fixes; I think also LOS 16 and 17.1 are not actively developed, changelog for both is rather empty for the latest months. So I guess any recent build is fine, I am not expecting any change in recent builds.

In both LOS 16 and 17.1 LTE is not working, the sim card is not seen and it cannot be accessed. Any hope or workaround to have it working ? It's the only missing feature to declare LOS 16.1 almost perfect.

I'm in the same boat, also tried 16 and 17 but opted out for going back to stock as I want LTE to work. As far as I know, there is no workaround. It's a shame really as it's still a really good tablet and a fully working ROM could give many devices a second life.

 

[Vuche]

Yeah, apparently no one could sort it out, lte models won't have the modem/sim working. But you can still install lineage 16 or 17 if you don't need the lte part.

I have one 8" and one 10" WiFi only on which I installed latest possible Lineage. I also have the 10" lte model where I kept the original Android 7, It's working fine for watching TV-Netflix on the go and most of my needed apps.

But still, as I said in another thread, manufacturers should open source their software/bootloder for end of life devices, they wouldn't lose anything in my opinion, as not all users would have the skills or time to change OSs.

Thanks anyway again for keeping our beloved S2 alive and kicking!

 

[enryfox]

Keeping the stock ROM is an option, but a) is bloated with goggle and samsung stuff you cannot remove (and some of the samsung stuff no longer works at all) b) android 7 is slowly but inexorably loosing apps support - and one such app is nova launcher (android 8 minimum) which to me is a must.

I like LOS 16, it is lean and clean and I can choose to install only the minimal google apps I use; I will have to live without LTE (99% of time the tablet is used at home). My S2 would also need a new battery, but i'm not sure it is sound to invest money in it. Really glad it still works as a reading/youtube/Netflix tablet albeit with wi-fi only and a limited autonomy.

Regarding a), if you don't want to root, you can remove system apps with adb:

I would recommend changing battery. Did it with mine as it started rebooting itself when battery was getting low.
If you don't need LTE, LOS 16 is probably the best choice.

Yes, mine is doing that too, at 15% of battery it reboots itself; peak current is no longer what it used to be...
But indeed battery life was not one of its main feature, even when new the superbright OLED screen would kill the battery pretty quickly, and Samsung was in full "let's make it thinner as possible" swing resulting in a tablet that is insanely thin (even by today standard) with a not so big battery.

 

[ginore]

How do we replace the battery of our S2?
Is there any guide available?
Thank you

 

[Paulkw]

@ginore It's fairly easy. I followed this tutorial
