This is an unoffical build of CyanogenMod 11 for the Samsung GalaxyTab 7.7.
Although it still have many issues, it is quite interesting to take a bite on the KitKat. I never expect we can go this far..

Release Note:
It has be too long for the cm-11 update. I was stuck at the settings for sometime. The performance settings is replace with Omni's. As lollipop is out, this would be probably the final build.

Finally get cm-11 boot! In this build, new kernel is included, GPU settings are added to performance settings. Hoping any 7.7 devices may get a stable GPU O/C settings

Haven't updated the cm-11.0 for a long time. Just waiting for a more stable release. Cumulative fixes from other builds are included. Locationging problem in 4.4.3 is fixed in 4.4.4. Bettery life seems better too! Don't forget using the latest Gapps for 4.4.4.
Requrested by local friends, the Alipay link is added for Donation.

This new build include all the fixes in my Slimkat + Incall screen is fixed! Sames as the dialer, the inCall screen is portrait now.
For some unknown reason. screen is distorted after rotation found in few apks (like build-in Browser). Same fix in Slimkat doesn't work for cm11 and Omni... However, a simple relaunch from recent menu will fix that. That would be the only minor issue left....

Finally, bluetooth headset is fixed! Cheers!
During calls, press bluetooth headset button once will direct audio to headset press again will end call.
VoiceDialer is not working with bluetooth yet but Google seach can be activated by pressing bluetooh button.
Only mirror issues left so it is reaching beta now...

So long for an update! Finally fix the bootloop in bluetooth this weekend. Wifi ON/OFF loop is fixed. Quick fix in Camera as Omni. In this new build, WiFi-tethering, WiFi-direct and limited bluetooth is working now.
AFH and are back to normal now!

It was a productive Christmas. I finally find a way to keep both WiFi and mobile data. Not a good way but it works.. Seems it's worth missing the Christmas dinner. Uploading now I can start with bluetooth now. Another long long road ahead!

It was a productive weekend. Manage to fix the backlight and light sensor. GPS is also working now. For the camera, preview and auto focus ok but can't save any photo... A patched gapps-20131113 and a stable 20131031 were uploaded.
For ART, I've tested it in my Nexus7 with SlimKat (AOSP based. I plan to build it for our tab later). Same result, crash and PLAY is not usable. That would be a good news since it is not hardware related. Will test again right after Factory reset later.

I began trying this right after finishing download. It is harder as expected. The source itself is an alpha release. I can make it boot after stuggling for a while but our old mali blobs are no longer working with the new opengl. Screen color was messed up. All HAL driver not working properly... I finally patch the platform and fixed some of the problems this weekend! It is just presentable now. Very glad that it comes before the official builds...

Great! Can't wait for this to be good enough for a daily driver. Thank you.

PS. Any chance you can put you device tree/kernel etc on github? It's been quite a while since you last updated them from the looks of it.

Installed it, and will use it for a week as a daily driver.
actually, no major issues, all are cosmetics.

nothing to add to the bug list you mentioned for me now.
GPS not working yet, but i got a lock on my location in Google maps !!

transient noises are weird really, yet i only use the tab in portrait mode only

also, in lock screen, it says no SIM Card.
I put a SIM card and i make phone calls.
for me the most important in all this minor issues is screen backlight.

WiFi drops sometimes during usage.
and sometime, it doesn't want to re-connect again to the access point until i reboot the tablet.

V-Sync is broken .. that results a tearing when try to scroll something fast, and sometimes the notification end line
