Did you do a direct comparison of something like the same image? Vanilla Android has much more muted colors than TW, but you can always get a theme for higher contrast. As for brightness, I'm not entirely sure, but it's probably the muted colors. If you want the high contrast mode Samsung has for high light situations, get mDNIe Tuner by searching for it on Google.
[Galaxy Tab S2 Android Development] aldude345:
Yes same screens mine was just way duller and not quite as bright just found it interesting as it took away the vibrancy as other tablets lack
[Galaxy Tab S2 Android Development] Zacharee1:
Same screens or same thing on the screens?
[Galaxy Tab S2 Android Development] aldude345:
Same exact things on screen. I even restored to TouchWiz to verify what I thought and sure enough colors and brightness were off
[Galaxy Tab S2 Android Development] Zacharee1:
Well try the mDNIe Tuner thing and play around with the options.
[Galaxy Tab S2 Android Development] samsung_xoom:
brightness and colors should be i bit different going from stock to cm13, but shouldnt be enought to notice hugely, are you talking about when playing movie or general usage?

Hello, All CM 13.0 releases can be found here cm-13.0-20160715-UNOFFICIAL-gts28lte.zip

can not flash SM-T715
[Galaxy Tab S2 Android Development] vshapke:
Hi peeps. I am unable to get this rom to boot. Heres what i done:

1. flashed T710XXU2CPD9_T710BTU2CPD9

2. booted in, set it up

3. flashed TWRP and backed up

4. flashed rom as instructed in op

BUT after rebooting the Samsung logo appears and then the screen immediately turns off (though the tab seems to be on because it gets hot and wont respond to anything but a reboot to download mode).

I have booted back into recovery after download and tried flashing rom again, same thing.

Tried all the steps i initially did as well just now, same thing, after flashing cm and gapps the screen turns off after rebooting.

What could i be doing wrong?
[Galaxy Tab S2 Android Development] samsung_xoom:
your not doing anything wrong some roms are usable some are not, I dont have access to all the roms to get them bootable, but have gotten everyone to boot from my computer, there is issues with the bootloader with some of the roms, read through here you will know which ones are ok to use and which ones are not
[Galaxy Tab S2 Android Development] vshapke:
Ah ok thanks. I think i read most of it, no specifics were detectable.

Perhaps a link to the latest working build you know of? Thanks a bunch in advance.

Im not the lead developer on this, I can only fix issues or guide :)
[Galaxy Tab S2 Android Development] ad454:
Unfortunately, this link is for the Tab-S2 9.7" (SM-T81x). The original download link from T_I on the 1st post is broken.

Are there any working links to the actual CM firmware for the Tab-S2 8.0" (SM-T710)?

Thanks.
[Galaxy Tab S2 Android Development] sketchman16:
That IS the one. It says 9.7", but look at the filename. I've used it.

Even the ROM that boots and runs is not really usable. Don't DL it unless you want to help directly with DEV.
[Galaxy Tab S2 Android Development] samsung_xoom:
that is the last working one by the lead dev, I have been able to get everyone to boot but as far as I know thats last bootable one
[Galaxy Tab S2 Android Development] ari_88:
https://www.androidfilehost.com/?w=files&flid=76091

You can see that it is just where the development is storing each release (not gts28wifi<t710> and gts28lte<t???>) 20160711 is the last noted as bootable the newer ones say no boot
[Galaxy Tab S2 Android Development] samsung_xoom:
they can be bootable if you know how to fix it, but cam and mic still dont work, youtube is hit or miss, and minor graphical glitches
[Galaxy Tab S2 Android Development] tupacsoul:
Does It continue the development?

[Galaxy Tab S2 Android Development] samsung_xoom:
im not sure if t_i is continuing on the developement or not every rom that was made can be bootable, i have been working alot oon getting the youtube issues fixed, as i slowed down working on the camera portion. its only when i find fixes that i meantion them, as im not the dev
[Galaxy Tab S2 Android Development] tupacsoul:
Oki, thanks.

[Galaxy Tab S2 Android Development] MoonriseUnicorn:
If you make any progress on the lag issues / inability to play HD videos, can you upload a new image somewhere? It does seem that the original porting effort has stalled out. If that's not the case, and the original porting effort is still active, it would be great if the two of you could find some way to collaborate so that we could have a recent bootable image for testing.

The lag issue / video issue is really the major blocker here that's making this ROM unusable, at least for me. I don't care much about the microphone or the camera since I really only use my tablet for reading and watching videos. But the lag / video issues are a show stopper.
[Galaxy Tab S2 Android Development] T_I:
Oh, sorry, I'm currently battling with Moto G4 development based on ashwin007's code. Got almost all that I want working, except ringtones. Will start compiling for the tab s2 pretty soon again.

[Galaxy Tab S2 Android Development] samsung_xoom:
do you know how hard it is only the 2 of us working on this. problem is im spending most of my time working and t_i doesnt have the device. i managed to fix the boot issues, have it run smoother, normal video files can get faily smooth but youtube is a pain. camera and mic are still dead for me
[Galaxy Tab S2 Android Development] tupacsoul:
I know, sorry

[Galaxy Tab S2 Android Development] T_I:
I'd love to dive in and figure out which change in my code made them unbootable at one point. I'm dropping the Moto G4 development as other team took over and my phone works, so will resume working on the gts2 sources as of Monday.
[Galaxy Tab S2 Android Development] T_I:
Hmmm, did some compile work for the T810 and tried a run for the T71x devices and it looks that some T81x patches in the kernel broke the T71x kernel build. Needs more investigating.
[Galaxy Tab S2 Android Development] samsung_xoom:
so you broke it lol ;)
[Galaxy Tab S2 Android Development] T_I:
Nah, I doubt it, I ignored it. (to much)

I found 1 line of kernel code that prevented it to build. As we're not using debugfs at the moment, I've commented the line out. There were loads of commits in kernel and gts2-common since my last sync, so I compiled with just the one edit needed to get the kernel build just to see if one of the other commits fixed the boot issue. (probably wishful thinking)
[Galaxy Tab S2 Android Development] lewmur:
The 0823 ROM still fails to boot on my T710.

---------- Post added at 11:44 AM ---------- Previous post was at 11:26 AM ----------
[Galaxy Tab S2 Android Development] T_I:
Then some update in gts2 kernel or gts2-common since 11-07 killed the build. Will need to figure out which update it was.
[Galaxy Tab S2 Android Development] lewmur:
I tried them all and the 11-07 ROM was the last one that worked. So, the change came in the very next ROM, the first one from 12-07 at 8:24AM.
[Galaxy Tab S2 Android Development] samsung_xoom:
dont make me look at them again please.....lol
[Galaxy Tab S2 Android Development] T_I:
I started wondering, is de selinux in de 11-7 build permissive or enforcing?

I'm building the Moto G4 code permissive and gts210wifi code enforcing, but I can't remember which one I used on the gts28 builds.

As I'm not sure what the selinux setting was, I build with selinux permissive, as enforcing with incorrect sepolicies results in a non-booting device. With some luck we know where to look, without it, we now where not to look. Uploaded test image.
[Galaxy Tab S2 Android Development] zxmmy:
still not boot。。。
[Galaxy Tab S2 Android Development] T_I:
Only thing else I can think off is using common blobs that aren't as common as we thought. Uploading new build.
[Galaxy Tab S2 Android Development] samsung_xoom:
if its not figured out by next weekend Ill take a look at it, been swamped.
[Galaxy Tab S2 Android Development] nostupidthing:
Thanks.........
[Galaxy Tab S2 Android Development] nostupidthing:
has we reached the evolution dead end of tab s2 8.0?
[Galaxy Tab S2 Android Development] samsung_xoom:
T_I keep looking at the last workable bootloader, which works with the current and last rom you compiled. Leaving it the same as working bootloader, adding it to the current (if done right will get your bootup), anyone has questions feel free to ask, should I find a place to upload a bootable rom for us? this way we can go back to making things work and stable? any free locations for the file would be nice, then T_I will see what happened when he looks at it....but thats with T_I's permission........
[Galaxy Tab S2 Android Development] T_I:
Can you do a boot with the incorrect bootloader and catch me the last_kmesg before you restore? Taking a workjng bootloadr gets it installed, but I need to figure out what changed to make it non-booting. Am I missing a kernel option, blob, selinux setting,... At the moment I can't figure out what the diffrence is looking atbthe commits of the sourves, as there aren't any betweenn june 11 and 12.

Sent from my T810 running cm-13.0
[Galaxy Tab S2 Android Development] samsung_xoom:
I'll have to whipe out and go to the non-working ones. and if I remember right there was a few minor things, Ill have to go back and look, plus side I did happen to get every option bootable, but until every option is working would be hard to get nightlies and finish whats needed to get things smooth.
[Galaxy Tab S2 Android Development] T_I:
Thanks, can you also get the /proc/last_kmsg after a failed boot? (or tell me there isn't one, then kernel didn't even start)
[Galaxy Tab S2 Android Development] samsung_xoom:
thats all it allowed me to do with the latest rom, wouldnt even install.
[Galaxy Tab S2 Android Development] nostupidthing:
could we have a true dev who has t710 to work on this...... :crying:
[Galaxy Tab S2 Android Development] samsung_xoom:
sadly thats only me. but i dont have the time to tear it down and fix it. life of a soldier doesnt allow much time.
[Galaxy Tab S2 Android Development] nostupidthing:
what a pity...

they said the t713 would have better dev support because of a more open snapdragon cpu, but it seems the prolbems is no real dev buy samsung's tabs , only google's
[Galaxy Tab S2 Android Development] samsung_xoom:
i loved the xoom, i was a dev and was so easy to work with samsung is alot harder to work with
[Galaxy Tab S2 Android Development] T_I:
Hmmm, it should at least install.

As you've developed for the xoom I guess you know how to grap the last_kmsg. (after failed boot in twrp advanced, terminal and copy)

Guys how can I install stock mm on 710 ? I'm still on 5.1.1

[Galaxy Tab S2 Android Development] beitme:
I don't understand this. After i bought the nexus 9 I'll never buy another google phone again. That phone was of such shoddy manufacture, had so many problems, why would anyone (especially developers) continue to buy those products?
[Galaxy Tab S2 Android Development] furyin:
Has this project died? Was really looking forward to this port!
[Galaxy Tab S2 Android Development] ad454:
Me too! Especially since without a ROM like Cyanogenmod, I basically just have a paperweight.

When I dropped my previous S 8.4 (T700) in a hotel lobby on a business trip last summer, and bricked it, I had to get a replacement.

I thought that the S2 8.0 (T710) would be a nice replacement, despite the lack of IR and camera flash, since it had a nicer form factor for me. So I quickly snapped it up when there was a really good sale on it.

However, for the last few months, I have not touched it at all.

I never put too much thought as to how indispensable (especially for privacy, security, and functionality) cyanogenmod and root access was on my previous S 8.4 tablet, until I realized that now that I am stuck with the really horrible and useless Samsung stock S2 8.0 ROM, which is why I don't use it.

At best I need to wait patiently for Cyanogenmod (or another decent ROM) to be fully ported to the S2 8.0 (T710), while slowly saving up for a new Android tablet replacement which I can use. I also wish to learn more about Android ROM development and porting, but that is a very high hurdle for me considering my lack of experience and lack of spare time with work and personal obligations.
[Galaxy Tab S2 Android Development] nostupidthing:
YES YES YES!

Since we have 9.7 offificla, it shouldn't be too much troubles to have 8.0 official as well... Right? Right? :D

Wanting to flash CM14 on my T710
[Galaxy Tab S2 Android Development] nostupidthing:
because it's google, it's got stock android, its' got unlocked bootloader, it's got guaranteed and timely update for 2-year

here we're at the mercy of samsung and [MENTION=4557146]T_I[/MENTION] to give us a ROM that's not totally crap :D
[Galaxy Tab S2 Android Development] T_I:
The biggest issue I have at the moment is that I can't debug why it's not booting. (And didn't have time to develop for a few weeks due to work that had to be done in the house)

I hope I can find some time next week to dive into the boot.img of the working and non-working images to find a difference I can trace back to a change in the code.
[Galaxy Tab S2 Android Development] WalterCool:
There is some way I may help to proper debug it? I meant, do you have some steps to follow and provide you the logs you need?

[Galaxy Tab S2 Android Development] DroidIt!:
Tried last night. Somebody said flashing the 810 TWRP would work. When I did that it wouldn't boot to recovery. Then I took the ROM and modified the updater script to skip the device check and it wouldn't boot. So, AFAIK we'll just have to wait. :(

How to modify the t810 twrp & cm 13 to work on t710
[Galaxy Tab S2 Android Development] DroidIt!:
Hey T_I :) I was just wondering if you've had a chance at all to look at the 710. I have the 810 and my wife has the 710 and she loves her tablet. I noticed the CM 12.1 build works flawlessly and was wondering if you've had a chance to look at CM 13 or 14 at all for the 710. Just curious. :)
[Galaxy Tab S2 Android Development] T_I:
Recompile, as the T710 has a different display, amongst other things.

Just did a recompile with the latest kernel patches and cm-13.0 sources. Would be nice if it works, but somehow I guess it won't (but can't test, no T710)

I'll recompile with the old kernel sources tomorrow, as I've found that the kernel is the culprit. Updated OP.

Edit: did the recompile, added links to both versions in changes list. I hope one of those work. (or even better, both, but I doubt that)

When someone tests and needs to restore. Before restoring, please go to Advanced -> Shell in TWRP and copy /proc/last_kmsg for me, so I can check where the kernel had an issue.
[Galaxy Tab S2 Android Development] dbodily:
It didn't boot, as you expected. I've attached the last_kmsg from my boot attempt.

I hope I did this correctly. This is my first post and attachment.
[Galaxy Tab S2 Android Development] T_I:
Yes, it helped. It confirms my suspicion, kernel issue. (although, I hoped I'd fixed it)

I had the same issue with my T810 cm-14.1 build. Completely rebuilding my development tree helped there. I'm now compiling T710 code for cm-14.1. (that kernel is sound for T81x and should be for T71x)
[Galaxy Tab S2 Android Development] dbodily:
I'm glad that helped. I'm looking forward to trying the 14.2 code.

Thanks.
[Galaxy Tab S2 Android Development] T_I:
I've build a 14.1 image and placed it at https://www.androidfilehost.com/?fid=457095661767116606. I hope it works.
[Galaxy Tab S2 Android Development] DroidIt!:
Ugh, you're killing me. :p I really want to flash, but the 710 is the wife's tab and so now I have to wait to Monday to get it away from her! But...need...to...flash now! :rolleyes::cool:

:) On the upside it has been downloaded 28 times and no complaints here, so must be a successful build. Great job dude. Would be nice for a silent observer to chime in though. :)
[Galaxy Tab S2 Android Development] risant:
again not working the boot stuck at samsung tab s2 logo
[Galaxy Tab S2 Android Development] lewmur:

Problenatic custom rom from the beginning
[Galaxy Tab S2 Android Development] SS2006:
Hey guys. So I installed latest image cm-13.0-20161114 from stock rom using twrp. All seemed well but on boot I get a red message at top saying kernel is not seandroid enforcing.

What did I do wrong?
[Galaxy Tab S2 Android Development] Zacharee1:
SElinux is set to permissive. It's a status message.
[Galaxy Tab S2 Android Development] SS2006:
Tablet doesn't boot tho. Goes black
[Galaxy Tab S2 Android Development] lewmur:
Yes, they've been working on the boot problem for some time. But it has nothing to do with the SElinux message. That message appears quite often with ROMs that work just fine. It is merely letting you know the tablet isn't protected by that security app because the tablet is "rooted".
[Galaxy Tab S2 Android Development] Zacharee1:
SELinux can be set to enforcing on a rooted device. It's a kernel flag.
[Galaxy Tab S2 Android Development] lewmur:
The ins and outs of SELinux are way to complex for discussion here. I was merely trying to give a simplified assurance to the poster that the message had nothing to do with the booting problem in this case.
[Galaxy Tab S2 Android Development] SS2006:
Oh ok. So I basically flashed a rom that is known to not boot. I thought it worked. Or is there a specific upload that is known to boot.
[Galaxy Tab S2 Android Development] lewmur:
Yes, there was an earlier version that worked but you'll have to check back through the thread to find it. I don't remember at the moment.
[Galaxy Tab S2 Android Development] SS2006:
Yes the 20160711 build works. Can anyone confirm if any build after this worked? And any plans for cm14? Would love to donate. Thanks

"If you haven't run stock Android 6.x, flash that first with odin. (image won't boot without this step)"

I don't get this step and being the first, well, obviously that's a problem.

All I want is bone stock Android on my sm-t710, I don't care if it's earlier MM or not...where/which ROM is this referring to? It may be all I need?
[Galaxy Tab S2 Android Development] lewmur:
This is NOT a stock ROM and you'd still need to install the stock MM before you could install this anyway. Even if it were working. You can find instructions in this thread. If you are in the U.S., you need the ROM for "Cellular South".
[Galaxy Tab S2 Android Development] T_I:
Indeed, I tried a lot, but can't figure out why the tab doesn't start the images after 11-7. Looks like a kernel issue, but without access to the device it's hard to debug.

To be honest, any image is usable for everybody. With the stock 6.0 you install an update in one of the loaders, which you need to boot cm 13/14. You won't even need to keep it long on the device, boot, reboot to recovery and wipe + install cm.
[Galaxy Tab S2 Android Development] lewmur:
Any image is usable if you are going to immediately overwrite it with a custom ROM. But what the poster says he really wants is just stock MM for his tablet. In that case, he needs the one for his region. I don't think he ever read any of the original discussions about installing MM on his tablet and they have all kind of disappeared.
[Galaxy Tab S2 Android Development] Sarum4n:
