This boots just fine on my t710, with Gapps (pico) and without. I haven't had a lot of time to test it but it is very laggy and some sections in the settings (Security in particular) keep crashing on me.

A red frame keeps appearing briefly around the screen when attempting to do anything. I'm guessing display driver related? It's interesting that the red frame does not appear during the initial setup...It only begins after I get through the setup.

I flashed SuperSU without any problem and have root.

I can provide any feedback and logs if needed although I may need some help with that.
[Galaxy Tab S2 Android Development] ElectroNegative:
I did some searching about the red frame issue and it seems that it is related to "strict mode" being enabled under developer options. However, strict mode is not enabled on this t710. I even enabled, disabled and rebooted to see if that would help...no luck there.

In a brief test, Bluetooth seems to work with my headset, WiFi seems to be working as expected, YouTube streams well but only 480p, no random reboots yet with tweaking and light use.

The lagginess improved a bit after freezing some unnecessary system apps and disabling animations. Accessing the file system, such as with a file manager is very slow. I'm now wondering if that's the main source of the lag.

I have CM12 on my T710. Will I still need to flash stock Android 6.1 first as per your instructions or can that step be skipped. Thanks for all your work on this!
[Galaxy Tab S2 Android Development] T_I:
The stock 6.0 flash is mandatory, without it your T710 won't boot. The stock update flashes code in the bootloader which allows the tablet to boot android 6 and 7 code.

As you need to flash it for this fix only, any stock image will do. (country/region independent)
[Galaxy Tab S2 Android Development] T_I:
Ok, got a booting LineageOS 14.1 (no bootanimation though). Will create new thread for the T710 and T715.
[Galaxy Tab S2 Android Development] Znil:
Thank you so much for the effort :good: :victory:
[Galaxy Tab S2 Android Development] T_I:
[MENTION=7223932]Sarum4n[/MENTION] gave me his tab as a loan to test, that helped a lot.

Abandoning this project, switching to LineageOS 14.1, mainly because Cyanogen killed of CyanogenMod. (and I switched to 14.1)

For camera couldnt we port over the s6 camera, and use the original source off the stock rom?man starting to miss how much easier the xoom was for working with

Here's a few screenshots about battery life which is nice for a beta build (using bitorrent, watching a movie,checking mail, facebook, xda app of course!!) General performance is nice , few lags while loading some apps or refreshing a page and as i said earlier videos are lagging, for example in facebook they're like in slowmo ( had the same issue with first build of cm12 on moto g 2nd gen) Same thing for the drawer and ui which can be laggy. But for a 1st build this is promising.
[Galaxy Tab S2 Android Development] samsung_xoom:
Do you how the mic and camera was fixed on the 810? I had to revert back to original 6.0. I couldnt get it working. Not sure if you will be tackling that or not?
[Galaxy Tab S2 Android Development] T_I:
Yes, at least the camera. We used the device specific hardware blobs instead of the T815 for all devices. Mic worked as soon as we did the split for the camera.

The latest T710 build is with the T710 hardware blobs. I'm currently building for Moto G4, but if this build fails (haven't got it working yet) I'll do a rebuild for T710 and T810 to see is updates in common and cm itself solved some issues.

Edit: Recompile with latest patches done and uploaded, updated OP.
[Galaxy Tab S2 Android Development] samsung_xoom:
Camera and mic was the only reason had to revert. Need those for business, i couldnt get it working on my own
[Galaxy Tab S2 Android Development] Mixikins:
This latest build boots and everything seems to be fine except for the camera and mic. Recording from a headset works fine however.
[Galaxy Tab S2 Android Development] samsung_xoom:
Yes i know all is fine minus the 2 things, and minor glitches
[Galaxy Tab S2 Android Development] T_I:
Good to read the only issues are with mic and camera. Started compiling for T715 as wel. Hopefully those are the only issues left. This opens up a new source of testers to get logging for debugging.

Sent from my T810 running cm-13.0
[Galaxy Tab S2 Android Development] Lupin The Third:
I know this is not related here, but hopefully we will see some development for the new t813 snapdragon variant :)
[Galaxy Tab S2 Android Development] samsung_xoom:
I tested it quite well. Put it through the ringer, minor graphics issues pop up but nothing major. Cam and mic i tried to get working no luck though then again could be doing something wrong. I did have a hickup with bluetooth on one of my devices but pulled it off. Memory mgt seems good, only had issues with a couple games fps went unplayable but other then that compiled a solid rom.
[Galaxy Tab S2 Android Development] mysa50:
Am i the only one geting lags with videos on YouTube and facebook, it lags like hell and won't charge making them unwatchable
[Galaxy Tab S2 Android Development] samsung_xoom:
clear cache and try again, also turn off hardware accel...
[Galaxy Tab S2 Android Development] mysa50:
Already cleaned cache and it didn't change anything, hardware acceleration is disabled i guess as i didn't touch anything in développer settings that's weird at first video load without problem and finally get stucked sometimes i still have the sound running but not the image
[Galaxy Tab S2 Android Development] sketchman16:
So far I notice it both boots and runs slower than stock.

EDIT: Woah. Skype is insanely slow. Yeah, this is not usable currently. Skype just trying to load a convo brings it to its knees.

I'm keeping a backup to flash back and test new builds. Hopefully that'll help. And if there is anything I can do to help via logs or something lemme know.
[Galaxy Tab S2 Android Development] Bai-long:
It's quite laggy, but will keep using it as I only use it as music and podcast player and satnav. Happy to provide debug logs if needed, so we can get a working, bloatware free tablet.
[Galaxy Tab S2 Android Development] T_I:
I did a recompile with the latest CM updates. Would like to know if this image has different issues as the one before? (or even better, mic and camera are working)

When mic and camera are still broken, coud someone get a logcat when they try to use the devices, so we dan locate the cause? I can't think of a reason why the device shouldn't work. It does on T715 and they have the same hardware.
[Galaxy Tab S2 Android Development] samsung_xoom:
Ill download newest o e and test it again ill get news after testing, keep you posted

new rom, does not make it past samsung seandroid screen, dead in the water

---------- Post added at 07:11 PM ---------- Previous post was at 07:09 PM ----------

did you change anything in the boot loader?
[Galaxy Tab S2 Android Development] T_I:
Complete clean build, unchanged sources. Must be the blobs, they tend to disappear after a repo sync, pulled them again and recompiling.
[Galaxy Tab S2 Android Development] samsung_xoom:
ok keep me posted, I will keep an eye out in the am for the build. and I did see some of the issues that were posted about the rom, I cant confirm all of them, Im going to see what I can come up with for the lag, I did not have issues with youtube. so I cant confirm that one. the lags with the os that people are experiencing, I maybe close to a work around but I will wait to see what happens on the next rom you make available see if the things pointed out are fixed. youtube I think i have fairly smooth will know more tomorrow
[Galaxy Tab S2 Android Development] Bai-long:
Youtube HD videos don't play, SD is fine.

7/14 fails to boot on my T710 coming from Cellular South 6.0 ROM. 7/12 failed to even install. 7/11 currently testing.
[Galaxy Tab S2 Android Development] T_I:
Ok, recompile, clean, blobs taken from TheMuppets (repo used by CM) and first build on T810 to see if common blobs are correct. OP updated. I hope this one boots.
[Galaxy Tab S2 Android Development] samsung_xoom:
same screen then shuts off just before the cm13 logo

---------- Post added at 05:52 PM ---------- Previous post was at 05:33 PM ----------

T_I I also dont believe we are quite yet at beta stages, more in Alpha since we only have one bootable image, and the rest failed to boot.
[Galaxy Tab S2 Android Development] lewmur:
Tried 7/15. My 710 doesn't really shut off, though it appears to. The screen shuts off but I have to use Home, Vol -, Power buttons before it will restart. IOW, it hangs just before it would normally show the Sansung or CM splash screen.
[Galaxy Tab S2 Android Development] T_I:
I'm working blind, as I don't own the device. When nothing changes in the code, the result should be the same with either compile runs including the gts210wifi or with clean compiles.
[Galaxy Tab S2 Android Development] lewmur:
Only thing I can suggest is that you examine what changed after the 7/11 ROM. That worked while everything since hangs just when the system itself starts to boot. IOW, the bootloader loads, and if you've chosen to boot revovery, it works. But if you chose to boot the system, it hangs just as the splash screen starts to load. Whether the first screen blanks or stays displayed, seems irrelevant.

edit: I realize you are working blind and appreciate your patience in trying to work that way. It is much appreciated. I have both a T710 and T810 and a Linux desktop with an 8 core processor, 8gb of RAM and a 250gb SSD to work from. I have never tried to compile a ROM but I am an experienced programmer/consultant. (I'm 77 years old and and built my first computer in 1978.) If you'd like me to help and care to explain the build process and what I'd need to to it, I'd be glad to attempt it.
[Galaxy Tab S2 Android Development] samsung_xoom:
ya thats the downside, I remember doing that for the xoom, and the s2. Was a pain in the butt. you were close, just something going on in the startup. Sadly thats just the way things go when doing things blind. I have been working on the work arounds for the issues others pointed out. time limited between work and finishing my move to the new house. right now trying to see why some people are having problems with skype and youtube.
[Galaxy Tab S2 Android Development] samsung_xoom:
T_I I managed to get the newest one bootable but still have yet to get cam working. all movies are playing smoothly. Still no camera. And yes I was right you changed the bootloaderhence the reason it was not booting into the os. I corrected the bootloader. now how do I get it to you to upload?
[Galaxy Tab S2 Android Development] samsung_xoom:
now the bad news....youtube playback issue seems like a common cm13 issue(tops out at 320p), some have fixes some dont. the slowness and glitches......thats due to the binaries we have for the device. unfortunately testing on a spare t710. Camera and mic, I tried 2 sources and was unable to get running. Also used sources from the t715 hoping would give us good news. Both attempts failed. T_I might be able to go further. sadly going out to the field for a while so wont be doing much on the cm13.
[Galaxy Tab S2 Android Development] T_I:
What did you have to do to get it booting?

That's to bad, but have fun. Camera and mic use stock blobs, which I took from a stock image. I've re-extracted the blobs today, will try a T715 build first (there I found a difference that can kill the boot), I'll recompile T710 tomorrow.
[Galaxy Tab S2 Android Development] samsung_xoom:
I swapped the boot loader from another date it booted up just fine. I was curious, with the changes so I inspected both dates looks like you made quite a bit of changes in the bootloader ( can be either tweaks, blobs, built in apps, those can make a difference).
[Galaxy Tab S2 Android Development] T_I:
Then it must be blobs, haven't changed anything in the code. Last commit in the tree is from July 5th. Doing a clean compile of both gts28 images again, with the blobs freshly from the stock images.
[Galaxy Tab S2 Android Development] samsung_xoom:
look at the size of your boot loaders, huge differences, and then look at the code, again was differences. seems like you tried to have it boot using less then previous hence why would not boot, I bet same thing would be with the t715 if I looked at it
[Galaxy Tab S2 Android Development] T_I:
Size of lte version varies a lot less then the size of the wifi versions. I've recompiled and I'm uploading a new build for the T710. Size is within variations I'd expect.
[Galaxy Tab S2 Android Development] MoonriseUnicorn:
It still doesn't boot. After the Samsung screen before the Cyanogen logo would normally appear, the screen just goes blank.

Also, FYI, in the original 13 build you made that I did get to boot, I had lag problems with IceCat scrolling, and page turning in Cool Reader. I know other people reported lag with YouTube videos, but I just thought I'd add a few more applications that had issues. IceCat scrolling was so slow that it was unusable. Interestingly enough, the built in browser did not lag when scrolling.

Don't know if this is helpful or not, but CTXz's 12.1 build doesn't have any of the lag problems. However, neither the camera or microphone work in that build either. The camera worked for a little while, but then stopped. Now I always get "Camera error. Can't connect to the camera."
[Galaxy Tab S2 Android Development] lewmur:
No change. Still does the same thing. Blank screen when CM logo should appear. Did a full wipe and installed ROM and gapps pico.
[Galaxy Tab S2 Android Development] samsung_xoom:
when I get back I'll see what I can do, I'll compile something and let T_I find me a way to send it to him. I can at least make all the compiles boot without issues. its the camera and mic I cant figure out if he can come up with the fix we can get a final product going. last 2-3 roms that were compiled I was able to fix the booting issues, but the camera and mic I couldnt.
[Galaxy Tab S2 Android Development] lewmur:
I'm curious, what's causing the boot problem?
[Galaxy Tab S2 Android Development] T_I:
My build on cm-12.1 for the T810 was based on [MENTION=6584695]CTXz[/MENTION] build and had lots of devices missing, but no lag, The CM-13.0 builds of the T810m T710 and T715 are based on [MENTION=3463426]RaymanFX[/MENTION]'s code for the T815 and somehow the lag popped up in the T71* models. Can't figure out why. On my T810 I only experience lag when I've been playing CSR racing (2) for a while, but not anywhere else. (But I don't watch video's)

I've found a patch in gts2-common that's been added June 12th. On T81* this patch solves a few issues. It could very well be that it breaks the T71* builds. Recompiling with the patch removed.
[Galaxy Tab S2 Android Development] samsung_xoom:
T_I my offer still stands if you need me to look at things before release it lol. I think I managed to fix and boot every release you posted. well when I catch up on sleep, your welcome send through skype or whatever. Im feeling bad for the ones that go to download to have it no boot.
[Galaxy Tab S2 Android Development] T_I:
I can inform you when I've uploaded the latest build so you can test, before I update the link in OP. Can't think of another way to get the image out. BTW the images are marked as experimental and untested, until I get a report if it boots or not. I know download and flashing takes time (so does building), but unless an image is marked as 'boots', people are willingly taking their chances.
[Galaxy Tab S2 Android Development] optionalmgrr.la:
Can you build 64-bit kernel with this?
[Galaxy Tab S2 Android Development] Lightn1ng:
Samsung have done some hardware-level dooshbaggery to disable that, as far as I'm aware.
[Galaxy Tab S2 Android Development] Zacharee1:
Thinking of getting rid of my extremely slow iPad 3 for a Tab S2 8.0. I'm really glad to see a CM13 build for it, even if it is experimental, since I love it on my Note 4. It's great to see that there's a chance I could have it usable by the time the schoolyear begins.

Thanks for making this.
[Galaxy Tab S2 Android Development] T_I:
Probably, but I doubt it'll work.

This could be the reason why I haven't found any Samsung 64 bit kernels in cm. HTC has one, but it's depended on hardware blobs I don't have for the gts2 devices in 64 bit.

Depends on which Tab S2 8.0 you're looking at, the T710 and T715 is subject to work. (blind, still have to figure out how to emulate the device so I can test) The newer models are snapdragon based instead of the Exonys which is the base for the older models. (T710/5 and T810/5)
[Galaxy Tab S2 Android Development] Zacharee1:
What do the newer models start with (number wise)? From what I've heard, Snapdragon is better for custom ROMs. If I have to pay a little extra, I guess I can do that. I also might end up getting the 9.7, since for some reason I thought my iPad was 7.9 instead of 9.7 :p. Is there development for that variant (is it the same development)?
[Galaxy Tab S2 Android Development] T_I:
The Tab S2 9.7 has development. (@RaymanFX and me) Both again on the older models. (T810 and T815)
[Galaxy Tab S2 Android Development] Zacharee1:
Well I think I'm going to go for the T813, just because it's better for things that need CPU power, and hope that one of you amazing devs builds an AOSP ROM for it. I'm going to wait a year anyway for the warranty to expire, and if nothing's out I'll settle for debloated Stock.
[Galaxy Tab S2 Android Development] MoonriseUnicorn:
Latest build from the 24th does not boot. No change from last time. It hangs at a blank screen after the Samsung logo.

I really think you should change the current state of this ROM from BETA to ALPHA in the OP, at least until the builds are consistently bootable. So far, only two of the builds have been bootable.

Thanks for all your hard work on this. I really appreciate it. But yeah, I'd say that for now, this is definitely an Alpha build, not a Beta one.
[Galaxy Tab S2 Android Development] samsung_xoom:
well Im half back, every rom has worked when you change bootloader. relatively simple fixes like I said managed to get everyone to boot. with reverting some blobs
[Galaxy Tab S2 Android Development] MoonriseUnicorn:
I followed your lead (at least I think I did) and replaced boot.img in the 7-24 build with boot.img from the known bootable build of 7-11. I was able to get 7-24 to boot after that. However, the touchscreen doesn't work correctly after it boots. Basically, it seems like the bottom of the touchscreen is non-functional, so I can't select options like Next, etc. when trying to set up the device. The onscreen keyboard also didn't work correctly. I could select letters, use the shift key, etc. But I could not change to enter numbers and such. Again, because the bottom part of the touchscreen appears not to be working. Interestingly enough, when I try to select something on the bottom of the touchscreen, I can see the notification bar drop down from the top of the screen.

Of course, I have no idea what's causing that. Whether it's because I mixed boot.img from 7-11 with everything else from 7-24, or whether there are other changes in the 7-24 build that broke the touchscreen.
[Galaxy Tab S2 Android Development] T_I:
Where does it say that it's anything but EXPERIMENTAL ? (apart from testing in the XDA typing, can't choose anything less)

Edit: Found 1 BETA between loads of EXPERIMENTAL. why do people always read the 1 edit I forgot instead of the topic and all other statuses in rest of the post. including the extra large, bold, red one on the first line of the post. Even the download dir is marked experimental...
[Galaxy Tab S2 Android Development] T_I:
Which blobs did you revert?

I'm at a loss here, as I haven't changed anything in the blobs, dtb.img or kernel configuration. As far as I know I'm still using the same blobs I did in the 11 build. I'll recapture them from the 11 build and try again.

Edit: 1 lib, gps.default.so instead of gps.universal5433.so (as in T810). Reverted to state of 11-7, will see if this helps.

Will first compile the T810 code to see if this change won't break gps in that build. (then we can keep this configuration the same on all wifi devices)
[Galaxy Tab S2 Android Development] samsung_xoom:
there i more then just using a boot loader from a previous date. you have to open her up and see what needs to be done and what was changed. its more of understanding changes, blobs and also, not sure if mentioned BUT not all the bootloaders can be swapped out with a specific date. sometimes it works sometimes it doesn't. my luck I have with it matters on how much I drink prior to looking at it or how much sleep I had lol

---------- Post added at 11:22 AM ---------- Previous post was at 11:19 AM ----------

if you go back through, some changed some didn't you'll know when you look at the bootloader size, and then open her up. if the size is different then for sure something changed.
[Galaxy Tab S2 Android Development] T_I:
I just pulled all libs from the 11-7 image and the only difference for the gts28wifi blobs was the gps library. (name only, not even content, just name)

No other change in the blobs, not even in the gts2-common blobs (last change there was 5-7)
[Galaxy Tab S2 Android Development] MoonriseUnicorn:
I do read everything, and I'm aware it's experimental. But to me at least, experimental encompasses anything that is not yet considered ready for full production use. Alpha, Beta, Release Candidate, etc. is a much finer grained indicator of what "experimental" means. To me, Beta means that the software is reasonably usable for daily tasks provided that you are willing to put up with a few missing features, the occasional crash, etc, where as Alpha indicates something that may not work at all and even if it does, probably isn't going to be suitable for daily use even by people who are willing to put up with missing features and occasional crashes.

Again, please don't get me wrong. I really do appreciate all of the work you are doing on this. I'm a developer myself, but I know almost nothing about Android development, so I wouldn't be able to get anywhere near as far with this as you have.
[Galaxy Tab S2 Android Development] T_I:
For me experimental is anything I haven't tested myself. As I don't own T71x devices, I've marked it experimental.

I'm no developer, I just have a T810 on which I want to run CyanogenMod. I've had a software development education over 20 years ago, but since then I haven't developed anything except scripts, that is, until I started in december. So I guess I had a bit of a slow start. (The currently used tools were the biggest issue)
[Galaxy Tab S2 Android Development] samsung_xoom:
