[ROM][UNOFFICIAL][13] LineageOS 20 for Samsung Galaxy Tab S 10.5 (SM-T805/SM-T800 - chagalllte/chagallwifi ) - Alpha

Interesting, again, i can only fix these issues with logs from the test build

I manage to fix WiFi using the old way for porting Roms back in a days of MTK porting guide fixing WiFi issue. I only replace the stock system/etc/WiFi/ folder and fixing permission, now I can say Everything working fine on my T705. Super smooth I down clock the CPU to 800mhz in order not to reach high CPU temperature. Working flawlessly. Thanks

Why not try the thermal mod settings if you're rooted, instead of reducing the clocks to such a great extent.

How to use thermal mod? I only use Franco kernal manager to reduce clockspeed to maintain the heating issue. I only use this tablet as my multimedia and browsing the web.

Yes it works using changalllte build

Can you explain the procedure ? Which files did you replace with ? Directly in the root ?
Thanks

Thanks a lot for porting LOS 20 to this old tab !

Everything works well for me on chagallwifi, exept the installation of some games (Monument Valley...). Other app install without issue.
I just get a popup "Impossible d'installer Monument Valley" (Can't install...) without an error code.

I did a "adb.exe logcat -v threadtime >logcat.txt" and there seems to be a CANNOT_WRITE error.
How can I investigate this issue ?

Thanks !

LineageOS 20 UNOFFICIAL for 2014 Samsung Galaxy Tab S 10.5 LTE/Wifi​

Model: SM-T805 (LTE) - chagalllte - 10.5" screen, Exynos 5420 SoC, LTE
Model: SM-T800 (Wifi) - chagallwifi - 10.5" screen, Exynos 5420 SoC, Wifi
These are the ONLY models that the ROM will work on.

You MUST READ posts 1-4 (about 10 minute read) before deciding to install this rom. If you think this is an unreasonable request, then stop reading now and find another rom. Thank you.

DISCLAIMER

I am not responsible for lost data, identity theft, lost money, security vulnerabilities, bricked devices or any other hardware or software malfunctions that comes as a result of flashing this rom.

All involved in bringing this build to you are working voluntarily on it in very limited spare time, and their other life commitments have much higher priority. Don't expect a prompt, or even any, response to questions and bug reports.

Before attempting to install this ROM

1. Ask yourself: would bricking your device be a disaster for you? If yes, don't try this ROM! It can't be guaranteed stable and reliable enough to depend on for daily use.
2. BACKUP YOUR DATA AND EXISTING ROM. Be prepared for a complete restore if anything goes wrong.
3. RESEARCH adb, fastboot, Odin/heimdall, and TWRP and how to use them, if not already familiar with these.

What works

1. bluetooth
2. wifi
3. brightness
4. external audio
5. audio through headphone jack
6. audio over bluetooth
7. selinux enforcing
8. DRM level 3 (SD definition)
9. deep sleep
10. camera

What doesn't work

1. Fingerprint is completely removed in 19.1 (According to @retiredtab it was not compatible with keystore2)

2. DRM level 1 (no HD definition).

3. Workaround to disable scoped storage. In 18.1 there was a workaround to disable scoped storage, but that no longer works in 19.1. So if you have a lot of apps or data on an external microsd, the performance may be severely degraded.

4. GPS (Works For Chagallwifi)

5. RIL (LTE/4G)

6. Aggressive Low Memory Killer ( Might Cause Apps to crash in some cases, @bluess57 Explained Here)

Will GPS be fixed in the future - LTE model?
