[ROM][7.x][T710][UNOFFICIAL] LineageOS 14.1 for Tab S2 8.0 2015

[T_I]

This ROM is BETA and not ready for daily use at the moment​

As of 8-7-2017 permanently marked as BETA.

The project started out as Experimental, as I had no device. Thanks to @Sarum4n it was temporarely BETA since 27-1-2017 as he loaned me his T710. Thanks to donations a used T710 came into budget and is available to test code.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community

First I would like to thank the following developers :

• @RaymanFX
• @CTXz
• @Sarum4n

I used @CTXz his T710 work and @RaymanFX's T815 image to base this lineage 14.1 build on.

Special thanks to @Sarum4n, as he loaned me the T710 to test the builds and debug the boot issue we had.

Before you start

THIS ROM IS ONLY FOR THE SM-T710

 * Your warranty will be voided !

 * I am not responsible for bricked devices, dead SD cards,
 * thermonuclear war, or you getting fired because the alarm app failed. Please
 * do some research if you have any concerns about features included in this ROM
 * before flashing it! YOU are choosing to make these modifications, and if
 * you point the finger at me for messing up your device, I will laugh at you.

Minor

• mic not working?

Instructions

How to install Lineage 14.1

• If you haven't run stock Android 6.x, flash that first with odin. (image won't boot without this step)
• If you don't have TWRP yet, get it from here : TWRP by ashyx
• Download the ROM and the Gapps that are located below to your device
• Reboot into TWRP by holding VOL UP + POWER + HOME on boot
• In case things go wrong make a backup
• After the backup has completed return to home and select Wipe and then Advanced Wipe
• Now ONLY tick Dalvik Cache, System, Data and Cache
• After ticking those, Swipe below to wipe
• Once the wipe has completed return to home and select the ROM
• After you selected the ROM swipe below to install it
• After the ROM has installed flash the Gapps
• When all of this is done, reboot into system, wait, and enjoy Lineage 14.1

How to recover from issues

Looks like the reset to recovery (<HOME><VOL-UP><POWER>) is still broken on some or all T710/5 & 810/5 devices with this build.

• Press and hold <HOME><VOL-DOWN><POWER> to enter 'download' screen.
• Select cancel <VOL-DOWN>
• Immediately press and hold <HOME><VOL-UP><POWER> to enter TWRP
• Restore back-up made during installation phase

How to ROOT

• Install the correct root package from here. (after flash of the image)
• In LineageOS 14.1 Enable the developer options
• Select Root access
• Select Apps Only
• Done

Questions and bug reporting

The following questions will be ignored

• Inappropriate questions
• Forced orders, EX. : "PLS FIX!!!!!!"
• ETA's
• Often repeated questions usually by the same user

Thanks, updated to 02 build. Bluetooth still does not work right. Pairing is slow and input is greatly delayed on keyboards/mice. Using one of those cheap mini keyboard/mouse remotes, but it used to work fine on samsung fw or other devices. What app can I use to capture a segment of the logs? I will try to test on some other Bluetooth device types in a bit, have to borrow some.

WiFi still has ccode set to GB in /etc/WiFi/nvram_net.txt, needs to be set to ALL or US to allow higher freq 5ghz channels.

I remember lower bounds of brightness being lower on Samsung fw, but that may have been with the auto brightness mode enabled, and then brightness sent to lowest. I assume light sensor is part of camera module, which still needs work.

Ok so yesterday, I took the bait and installed this room and so far I am impressed and really happy about it. the basics are fully functional and my tab S2 has found its breath again. Thank you for the work
One note though, the battery seems to drain excessively fast

 

[nostupidthing]

Please try to make this official so we can have regular updates including the monthly service security updates. Thx!!!!

Disable WiFi during sleep? It is on by default.
Also there is no adaptive brightness yet, so set it lower manually.

Left the tablet charging overnight. Screen was off. Picked it up and the whole thing was crazy hot. Did not have anythijg running in the background.

Sorry to say that for tablet may be faulty

It has never done that on Samsung marshmallow. Early lollipop has this heat issue which Samsung patched. Went back to stock rom, and no issues.

Beware of this issue, seems to be caused by lineage

Today is 3rd day on lineage and no problem with charging or heating over night.

Been using it since the first build with screen fix, 1/30 or earlier.
Tablet was fully charged for 6 hours, screen was set to off, was really hot when I picked it up in the morning, like it has been using 100% cpu.

Tablet gets pretty hot with cpu maxed for long periods, over 90c on any rom.
On stock rom there is a bug with chrome that causes this during use, as it does not use full gpu acceleration to render pages unless u alter flags.

Me and others have no such problems so. You may try reverting back to stock. Keep complaining won't help.

Reporting problems is not "complaining." The build is experimental/beta and has many issues. IMO this is a very important issue. Sustained heat can cause hardware damage. Much heat is dissipated through the glass screen and aluminum case border. If your tablet is in a case or bag supposedly sleeping, and this happens... you could see problems like warped case/melted adhesive around the screen. Possible that chippsets could burn out as well if heat is not dissapated.

I suspect it has done this 3 times in a week on lineage, it does not do it on stock rom. 2 of the times I woke to find the battery dead, so it drained in a few hours while sleeping. Other users have commented on battery drain iirc, and high cpu usage would be the cause. When on lineage and charging while powered down, there is no issue. The heat originates from the cpu location on the tablet. Likely it is due to a hung process that keeps restarting. I have had some system services that notify they have stopped responding on occasion while using lineage.

I suggest people running the rom keep a temp log and process time log.

your concerns well noted, notwithstanding it's still only you "reporting" this issue, as people are vocal with problems than those without, it's not likely that others are having the same problem.

since the dev has no such device and you're the only one having this problem, please try to contribute by providing more info e.g. logcat, process monitor...

otherwise there is not much @T_I and others may do to help you

I have been communicating with the dev on this thread and the last. I asked what tool I should use to report back the logs in the other thread, but did not get any constructive responses. Unfortunately "the tons of other people" who have installed this rom either fail to report back issues which have been stated by some others (bluetooth, wifi region, battery drain, etc), or don't even bother to create a forums account to reply. Instead, I'm met with s**tposters that spam rubbish to elevate post count such as "please support the 710" and "please add this or that feature," rather than looking into reported problems or actually offering anything constructive.

@Friagram With stock firmware my tablet gets also hot while charging it. I have no difference here with lineageos.

However, I have a little problem: my tablet hangs and does not react anymore on touch events. The buttons still work. Is there a way to reset the tablet with lineageos? A simple restart would be wonderful!
Otherwise, thank you a lot for this image. It feels really faster than with stock firmware.
Kind regards
Aurel

Still having bluetooth issue described in old thread.
@T_I logcat attached, near the end, from Bluetooth enable, pair attempt (headphones sb735, no pin needed) - fails to pair with any devices.

short battery life

Its great to have something new for this tablet, great work.

I'm also experiencing problems with power usage on lineage-14.1-20170202-UNOFFICIAL-gts28wifi with wifi turned off and tablet just left alone over night i get only around 12 hours from fully charged to ~5%

with cm12.1 I could use it moderately for days between charges (wifi auto turned off when screen off)

as a nice bonus my cheap "origami" type case now wakes and sleeps which it didn't do before with cm only stock. I don't think this is related to battery life though as i can lift a corner to peak under and the screen is off with the case flap down
