This is an unoffical experimental build of CyanogenMod 12 for GalaxyTab-7.7. Let's have the first taste of the colorful Lollipop.

CarbonLP is the winner. It is out now. Check the thread.

Release Note
2015/10/6
I just sync the marshmallow trees. That means the end of lollipop. I haven't update CM for a while because there is no significant improvement. I got an OTG last week. Finally, I can complete the support of it. USB storage is included in Strorage settings now. This is probably the last cm-12.1. It is Android-5.1.1_r24 (LMY48W). Enjoy the last lick.

2015/8/26
This build included a few extra things need to patch after the hard drive crash. The security breach in Android is fixed and some modification in media driver to make it more stable. Upper speaker is working in phone calls now. cheers!

2015/7/23
This is the test build after I reconfigured my hard drive AGAIN. Start again is always difficult but wiser. Finally, I have the "motivation" to face the few things squeezed down in the do list for a long long time...
I renewed the private lib for the wifi driver of the Athero chip. Now we can keep up with the current wpa_supplicant. The wifi ssid and password can restored now. I also set the default platform orientation to portrait (you may notice it from the boot animation). Rotations, call-screen and a few apps would behave like a phone (portrait) now. Note that this is a platform setting, it won't affect the kernel default. Recovery will behave as before. The SuperSU (if installed) entry is restored in settings.
The RIL library is also outdated now. The top speaker doesn't work during calls but bottom speakers and wire headsets are OK. Furthermore, phone calls would sometimes corrupt the audio driver... I think the next move would be keeping up with the current RIL...
Anyway, this is a quite stable build and almost all of the features are working now. Cheers.
History

2015/6/6
It's been quite a long time. Finally, the H/W decoder is fixed. cheers!

2015/5/2
cm-12.1 merge android-5.1.1_r1 now. The image method is no longer working. In this build, I use the old method in the zip. It might take longer (up to 10 min.) to flash but no more can't flash. 5.1.1 is quite stable. Lollipop is getting better and more stable now.

2015/4/19
cm-12.1 merge android-5.1.0_r5 now. In this build, I pick up the loose ends. GPS and some sensors are OK now.
Some p6800 owner reported failing to flash, I add the "a" version which use the old method in the zip. Those can't flash may try the "a" version. Cheers!

2015/4/4
Finally got cm-12.1 working. There are still some issues but it is quite presentable. PerformanceControl is included, bluetooth and wifi-tethering is working. Cheers!

2015/3/14
Struggling for a few weeks for the stability. Anyway, it's a time for a new build. zRam support is added to PerformanceControl.
5.1 was out last week. Omni was the first custom rom merging 5.1. I managed to build it out with little effort. Still have some glitches as expected but it is quite stable. I plan to release the experimental build shortly.

2015/2/25
The torch in QuickSettings is fixed. I knew it wasn't a decent job so I wait..(for too long). It took me a few days to find a neat way and has minimal changes to the original source. That's the final piece, Yeah!

2015/2/14
Although some commits gave me hard times, CM is getting stable now. Rush this out before the Lunar New Year. This long holiday, I'll take another look at the kernel and the SailFish OS...

2015/2/7
CM is adding its own features and gain quite some weight... Having hard time for a new feature which cause boot loop. Finally, I put a workaround to make it boot.

2015/1/25
I studied the newer (3.10.y and 3.14.y) kernel sources for a few days and nights. It is surely a mine field... Will start when my mind is ready. Only minor changes in cm-12.0 but it's about time for a new release. Cheers!

2015/1/10
It was a productive week. I finally unlock the last piece, mobiledata. After updating the RIL blobs and the opensource driver, I realized that the kernel also needed upgrade. I searched the Linux kernel.org and found a few essential commits. I cherry pick them and resolved the conflicts. Finally, mobiledata is workig now! Cheers!!!
This prove that our existing 3.0.y kernel is really outdated. Instead of bandages, I plan to make a new kernel for our tab. The latest stable 3.18.y is too far. I might start with the Linux 3.14.y which has LTS. If I success, it will probably the newest kernel for Android.
Those who familiar with Linux kernel are welcome to help!

2015/1/4
Happy new year! This is the first release in 2015. Found a bug in Bluez and it can turn off now. SCO and APTX modules are added.
I finally make the InCall screen rotatable. The only major issue left would be mobiledata. I think I fond the reason by not fixed yet.
Lollipop source gain a lot of weight. It took 5 hrs. for single build! My PC really need an upgrade.

2014/11/29
The new Lollipop has no decent manual. It took me a lot of time to study the source. Clearly it takes time to grow. Before going back to my final Kitkats, I biuld the alpha release. All models are inclued. Happy licking!

2014/11/18
After a few days and nights, I finally located the annoying bootloop issue at every boot. It is a barely presentable cm-12.0 now. Other than the listed issues, all the new UI features are working. Enjoy!

woah! this might be the best thing happened with this device i cant believe that you can go this far, keep up the good work!
downloading and testing now

EDIT: here's some initial impressions:
- initial boot took very long - almost 10 mins
- pretty stable, almost everything is working which is very nice
- sttuters everywhere, pretty much as your KK roms, probably caused by an old kernel
- YouTube video doesnt play at any resolution, the sound does play though, gonna test another video playback
- there's no option to turn off battery percentage on the statusbar
gonna use this ROM for daily driver for now
by the way, im curious about your DPI choice, why it is not 213? i found 213 are easier for my eye

Very weird for me as I cannot get the keyboard to appear to enter my wifi password.

I note that the H+ symbol appears on my mobile, so not sure if that is picking up mobile data or just a red herring.

I did use another universal gapps -> http://forum.xda-developers.com/andr...ition-t2943330

So maybe I am causing my own problems, but the gapps work on my oneplus without any issue.

Pay attention to the OP, its a known issue and there's a workaround to fix it
Simply skip everything in the setup guide and go to settings to enable the keyboard, then add your google account

Yeah, the new zip has different format. It's an system image. This way is faster and no need to set permission afterward.

Lollipop use the ART which take longer to boot at the first time.

The file in goo.im is ok. ~200M. It might take time to refresh.

See if you can see/edit APN. You can have mobile data if you can access APN.

Take a look at the last screenshot in post#2. It show you how to enable the keyboard.

Good luck guys.
