[ROM][UNOFFICIAL][10] LineageOS 17.1 for Samsung Galaxy Tab S 10.5 (SM-T805 - chagalllte & SM-T705 - klimtlte)

[bluess57]

Good evening. Will you be making Lineage 18 for T-700 as well?

At the moment no.
T-800 is boot looping, so no point attempting another device

 

[robbymarshal]

Do we have lineage 18 for T705

 

[Charuzu]

At the moment no.
T-800 is boot looping, so no point attempting another device

I understand, thanks for the response.

One more thing... About the fixed camera issue update for this current Lineage 17 rom, will you be re-releasing it?

 

[PureNihilist666]

At the moment no.
T-800 is boot looping, so no point attempting another device

I apologise if this is out of the scope of this thread, but is there anything I could do to help further the development of the 18.1 build for T700, seeing as I'm in the same boat as @Charuzu here and 17.1's performance left much to be desired. I'm currently running on 14.1 Deathly which is the only one with usable performance in my case.
Unfortunately, I'm not one with the programming knowledge to build 18.1 for the T700 myself, but would be more than willing to try anything that you could conjure. I'd be more than happy to provide any logs etc. that you require to figure out what has gone wrong if such a contingency does occur. I understand that you are short on time and thus wish to aid the development of our beloved tablets.

Unrelated to my main question, but how different are the T-X00 and T-X05 variants? I doubt flashing an T-X05 rom onto an T-X00 would go well but are there fundamental differences in roms between the two, besides the lte support and possibly accounting for the qualcomm/non mali variants?

You really don't need to be a programmer to build these roms, just a willingness to try, a Linux system to build on , some free disk space, an ability to read/follow instructions, use Google, time, post questions on forums when stumped for an answer.

As for tablet differences, I haven't closely looked at them all, but one example is battery size.
This is reflected in the kernel code as different code for driving the different hardware.
Hence you cannot run a T805 build on a T705

 

[robbymarshal]

Does anyone know a way to control thermals in lineage 17. The device is getting too hot

 

[bluess57]

some ideas->
Upgrade the thermal pads in the device- see the thermal mod thread

[MOD] Thermal mod of T805/T800 boost performance by 150%

I have this tabled for a long time, but as i rarely used it i didn't bother with it much. From day one back in 2014 the tablet was sluggish and laggy, today is just unbearable even for browsing. So i have decided to take a look of what can i do...

turn off location services/turn on battery optimizer etc

if you're comfortable with adb or have root on device , the scaling govenor can be changed.
By default it's been set to interactive in the kernel.
iirc deathly adiutor might do it , or some other kernel app.

using adb root shell

chagalllte:/ # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

For the former, there seem to be quite a few resources for building Lineage for un an unsupported device, XDA and Reddit may turn out to be my best friends, with WSL giving me a platform without having to install a seperate nix OS; leading to what is going to keep me occupied for the next couple months as I have all the time in the world.

For the latter, my question pertained to the respective 00 variant for an 05 device, like flashing a T705 rom onto the T700, or an T805 rom on the T800. The major difference seemed to be the cellular support (from what I can see on GSMArena anyway), as both klimt and chagall use the Exynos 5420.

Great I'm ordering some thermal pads. Plus I wanna know that I am getting 4 hrs sot with wifi and offline video playback . Earlier when on stock I used to just read books never turned wifi on and it lasted for weeks. Will getting a new battery after almost 10 years help or it won't make a difference.

A new battery is likely to help with better battery life, if you can get a real 7900mAh one.

Windows WSL might have some peculiarities, idk. A Dual booting setup is possibly better way, apart from buying a dedicated computer for linux.

Yes the main differences between Tx00 variant and Tx05 variant is the lte cellular hardware and kernel software to support it.

I'm sorry I didn't mention my model is T705 and it has a 4900 mah battery almost the same my mobile phone has on which I get 8hrs sot. So due to the size difference i kinda accepted the less backup on the tab. Thats why I got confused on getting a new one. Only the 4900 mah is available in my country costing 13$.

Slightly starved for space at the present moment, especially if I need to allocate space for caching, but I might try installing Ubuntu to an external SSD and run it off that if WSL does have issues. I'll begin with LOS 20 and work backwards from there if unsuccessful, especially seeing as if the possibility of further improvements exists like the ones that 18.1 brought over 17.1, I'd take them.

Don't try and start with LOS 20. Get a working 17.1 or 18.1 build going first.
There are too many unknowns yet re: LOS 20 , guarenteed it won't boot, whether it's even possible at all to run on these old devices.
And initially there is a fair amount to learn.

That's great to know, I see it'd be better to work forwards instead of backwards then.

Hi. Thanks for that great ROM. I am running it on a T705 and quite everything is working fine. Battery drain is okayish as well. However the video playback in the Chrunchyroll app stucks even at low quality. Netflix and other are doing just fine. Maybe someone could point me to a tweak to squeeze out some more video decoding power? Does it make sense to play around with the governor? BR

Edit.
I tried on your second firmware (LineageOS 18.1) and there is the same problem :/
On the Samsung soft all it works.

For bluetooth calls, no idea if this will work or not (it probably won't),

If you've got root / or ok with using ADB
Try setting changing these properties in the build.prop file
audio_hal.force_voice_config=narrow

and separately add this
audio_hal.disable_two_mic=1

From the log supplied, the bt_wbs is off, so above should align it with the bluetooth setting.

setAudioParameters for 30:10:B3:B9:FE:90: bt_headset_name=MEX-N5100BT;bt_headset_nrec=off;bt_wbs=off

Try setting changing these properties in the build.prop file
audio_hal.force_voice_config=narrow

Should i add it under this?
(audio_hal.disable_two_mic=1)

 

[bluess57]

That's fine, order doesn't matter

I'm sorry but that didn't solve the problem :/
