Nils is working with the source code posted in the OP. I certainly appreciate his input and help getting out updates. I got a Note 4 earlier this week so have been a little busy with that :)

Hi.

I have a small lag playing YouTube. Starts play few seconds then stops for 1-2 sec then continue.

Sometimes video is stopped but sound continued.

Any suggestions?

Otherwise This ROM is perfect.:D

thank you
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] RedBullet:
Got it. Awesome, Thanks to both you guys! I was ready to eBay my 12.2 and opt for something that was going to have a longer lifespan!

Thanks a ton to you guys, I'll be dirty flashing the new build on top of ,my #3 later today!

rotation and screen drawing

Does anybody have an idea on why the auto rotate doesnt work and how or when it might get fixed? I also see a bug in a game where the screen paints incorrectly and ends up with wide multicolored lines like a circus tent. A restart of the game fixes the problem but i dont know if its the game or the rom. The game in question is soulcraft if anybody wants to try to duplicate what im seeing.

Read post #4

Tons of useful advises...

:)
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] ktmdms:
Yes, I have Ultimate Rotation Control installed and it does allow me to do the rotation but it still strikes me as odd that this is broken. It's like some toggle didn't get compiled into the build to allow the kernel to recognize the device orientation and handle the rotation natively. Not a huge deal, just an annoyance, and was wondering if anybody was looking at it, that's all. Thanks.

I finally rooted my t900 with the UE firmware. I'm preparing to install CM. I installed TWRP 2.8.7 tar wifixx from a TWRP download using Odin which worked fine. Then I tried to flash all three of the TWRP 3.0 versions and they all boot looped. Anybody else had this experience? Seems odd that the official TWRP builds don't work.

T900

What'a the solution for random freeze on cm 12.1 I have tried all the solution but to no avail ...I reinstalled the Samsung 5,11 stock rom no random freeze ... please help
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] patt2k:
My apologies if I didn't find what I was looking for. Is there a thread with instructions how to install TWRP on T900? I only found some videos of people already running it. Anyone willing to point me in right direction?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] kb8no:
I was struggling as well. See my post 2 above yours. I figured it out today. Most of what you can Google for rooting and installing the custom recovery TWRP is from ROM's before Lollipop and my device came from EBay already with the Lollipop OTA installed. This T900 unit is called v2wifi but there are 2 main firmware variants, v2wifiue (North America) with firmware T900UEUBOJ1 and v2wifixx (Europe) with firmware T900XXUBPA1. It makes a difference which firmware you have. Since my OTA came from the US my OTA had the UE firmware. I was able to use CF auto root with Odin for v2wifiue. However, TWRP only has a v2wifixx version. I found that 2.8.7.0-v2wifixx worked with UE even though it was the wrong version but that 3.0 boot looped. I could only recover from the bootloop by using Odin to install the UE firmware again.

Then I thought that maybe the problem is that UE is non-standard and that XX is the standard firmware. So I got back to UE with TWRP-v2wifixx 2.8.7.0 where I was before the boot loop. I did a complete wipe and used Odin to flash the XX firmware. Then I used CF auto root with ODIN for the v2wifixx. Everything worked so far. TWRP has a 2.8.7.0-wifixx offered as a tar (all the 3.0 are img onlly files). So I used Odin to flash 2.8.7.0-wifixx. I then booted into TWRP and used TWRP to flash the latest 3.0 img.

BAM. JOY. T900 with v2wifixx firmware, rooted with SuperSU, and with TWRP 3.0. Grab the firmware from Sammobile, TWRP from their download site, and CF auto root from his site. It goes without saying to have USB debugging enabled., never to allow TWRP to install Super User, and allow TWRP to modify the system.

Now, if someone could explain to me why we need a P900 TWRP to install P900 CM 13 I could be much smarter than I am now. I can't see why the T900 TWRP 3.0 v2wifixx version wouldn't flash P900 CM 13. I want to try CM 13 next. Anybody?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] patt2k:
the tablet is on 5.1.1 with build number: LMY47X.T900UEUBOJ1. I am assuming it's running EU firmware.

EDIT: when I flash TWRP and then I enter recovery mode it always goes to stock recovery for some reason. I'll try CF AUTO root then flash recovery w/ root and TWRP app.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] kb8no:
No. UE is the North America firmware as I said in my post. You need the XX European firmware. If you are not rooted you cannot install a custom recovery (TWRP). You must use the correct CF auto root for your firmware. I advise you Odin the XX firmware and then Odin the v2wifixx CF auto root. Then you can install TWRP 3.0 for v2wifixx however you want to do it. Read my post carefully.

BTW, I'm now using Tapatalk on CM12 to type this message on my T900. Autorotate is working fine, I was expecting a problem. I have had a few crashes with reboots as people have described but it seems to be leveling out and I haven't had enough to figure out what triggers them. I'm pretty excited.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] patt2k:
This is the way I did install TWRP. Use CF Auto Root and then flash TWRP. But it's giving me error executing update binary in zip.

is TWRP 3.0 needed to flash? i installed 2.8.7.1 but i'll try 3.0 now.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] kb8no:
humm... 2.8.7.1 works. You don't need 3.0 (but you want it) so don't mess with it now. Did you Odin flash the XX firmware from Sammobile? Where do you get the execute binary error, in Odin? I did one thing at a time and then booted into ROM. 1. flash XX firmware 2. flash CF auto root. Get that to work first. Open SuperSU after you booted from CF auto root. Do you now have a rooted ROM? (Worry about TWRP after you have these accomplished.)
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] patt2k:
I get that in TWRP when trying to flash the rom. And no I didn't install the EU rom. I just did it the current one (yea I know I read what you wrote) if TWRP 3.0 won't work i'll do that, you mind giving me link to the firmware that you used from sammobile?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] kb8no:
Well, to the best of my weak abilities, if you don't care about TWRP 3.0, the TWRP 2.7 should work even you are installing a v2wifixx TWRP on a v2wifiue ROM. I'm thinking these two ROM's have slightly different kernels which is why they need different TWRP and CF auto root (as close as they are). I did not try go install CM12 until I figured out the XX ROM and installed it and then rooted it with the CF for XX and installed TWRP for XX so I can only guess at your problem. Just Google sammobile, it's the first hit. You have to register for an "account" for free and free takes an hour but the price is right.

I'm like you, since the TWRP 2.7 for xx doesn't boot loop and appears to work it should be able to flash CM12. Heck, the guys are using a TWRP from from the P900. But I can only tell you what worked for me and make assumptions. I do not find any of this discussion we are having anywhere so I hope somebody else reads this and benefits and adds some knowledge.

I do assume you booted the ROM and opened SuperSU before you tried to flash CM 12 and you wiped in TWRP before you installed.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] patt2k:
Hmm yea i'll play around with maybe a TW modded rom and see what happens. I will also try TWRP 3.0 and let you know how it goes.

Thanks for your time! i'll get back at you.

[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] jomar_uk:
Apologies in advance if a tad off topic.

My Tab Pro 12.2 developed screen flickering when at 60 - 65%, took to Samsung support site who after 10 days told me it was a screen problem, more worrying they said they had no replacement parts to fix now or in future & I was offered a refund of purchase price or another model (I choose the new 813 tab 2) which is great *but* really miss my 12.2 screen, has anyone else heard of no more 12.2 screens being made or available please?

Shalom & many thanks, john

you don't need a twrp from the note to install the note rom on the tab. all that needs to be done is to edit the updater script in the note rom so it doesn't check the device to see if it is a note and fail bc it is not the correct device...

Many thanks but too late for me. They kept it and as I said gave me a brand new T813 as a replacement, just a tad concerned they claim to have no spares to repair the screening my 12.2 Pro (they claim was the problem).

Many thanks anyway.

open rom in 7 zip go to meta/google/look for updater script pull to your desktop. get notepad++ and open is look for a line with device check ex p900 and delete the whole line. save the updated script then delete the current one in the open 7 zip of the rom and then drag your edited one there.

I hope this will help to buy a T900 or getting such a great work from you for CM13 :)

If you get CM13 running I will donate another $30

Hopefully all other users to donate too :)

BTW: the File from the 08/23/2016 is named CM-12.1-20160823-UNOFFICIAL-v2wifixx and the former files

where named CM-12.1.1-20160816-UNOFFICIAL-v2wifixx - so CM12.1 against CM12.1.1 - typo or why this backstep?

A guess in the blue..... but could it be the wrong Gapps.zip or a bad GApps-Build?

[MENTION=4817899]thompatry[/MENTION]: Do you got a Link for GApps which do work for you (on your P900)?

İ didnt know that the kernels are "swapable" between Android-versions...
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] javelinanddart:
A lot of devices have older kernels that you can make work on new versions of android. You shouldn't need to wipe to flash it with the new kernel, unless it starts glitching, in which case you do.

Just a quick update for everyone, I very close to having a final working build for everyone. I am looking at sometime late this week before releasing. If all goes well, I will be dropping support for CM-12.1 for the T900 and moving to supporting CM-13.0 full time. After I get good feedback from the CM-13.0 build, I will start working on N for the T900. So start getting excited!

This is a unique problem to T-900 with all non-TW ROM, or rather kernel. Some of the specific code come from crpalmer's T-520, and other parts from Valera1978 and bonuzzz P-900 build, where the screen is not exactly the same. I know that bonuzzz is working on a fix on OmniROM, but I don't believe chhaggerty, or hondong has looked into the issue for cm11 at this point. I suggest you contact [MENTION=2033742]hondong[/MENTION] in this issue, he most likely the one who could look into the issue.

Wow this rom is very slick! I was chicken to flash it after paying so much for this tab, but couldn't stand it any longer. I had a dell streak 7 for a few years. Man it sucked. Then last year I bought the tab 3 10.1. It still doesn't have a non TW custom rom (because of the x86 Intel Atom CPU). So this T-900 tab is my early xmas present. Needless to say I was dying to have the CM experience. Fast. Very fast. Don't be chicken! Flash it! You won't be disappointed.? And a million thanks to all who made this possible. It's just great!

[MENTION=2934677]chhaggerty[/MENTION], how did you generate the cyanogenmod_ defconfig for your device? You probably need to do more than just enable the variant which is about the only diff I see between them. The rotation problems may be caused by not having the right sensor devices built into the kernel. A couple of greps show me:

crpalmer@compile:/tmp/android_kernel_samsung_v2wifixx$ grep '^CONFIG.*_BMI' arch/arm/configs/cyanogenmod_* arch/arm/configs/v2awifi_00_defconfig

as crpalmer is busy with his note 4 ?, maybe i can look at this problem.

But where can i see which sensor setting is correct?

Sorry, i haven't created a full device config for cm until now, but with a little help, i think i can fix it.

[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] crpalmer:
No note4 for me. I like my phones to be phones and my tablets to be tablets....

Download the official kernel source for the device. See what defconfig they are using. Make sure that the defconfig that you are using is right for the device. My guess is that you want the v2awifi_00_defconfig (or something like it) and that the sensors are different and need different defconfig for them.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] hondong:
I have downloaded the source from Samsung and added the changes.

I think primaly it is BMI058 and not BMI055.

Gyroscope, Accelerometers and rotation vector is working now, but still no autorotation?!

Google Sky map and other Apps using the sensors are even working now.

Now Camera is not responding...

Feel free to install:
