This is the early stage. Many developers are working on it. Tons of updates are releasing every hour. I hope things would get better as before. I'll keep on trying. ;)

PS. I can upload the test build if anyone dare to try...:D

May be open new topic for CM12

Please upload if U have time want to try

Thanks
[Galaxy Tab 7.7 Android Development] scoobydu:
Ok cool thanks.

We need multirom support, so we can run slimcat and lollipop as secondary :D

Then we can really give it a test!

Upload it if you have time and you think its worth it at the moment.

You aren't building a latest CM11 build by any chance are you?

btw: I am just syncing the lollipop repo to give the compiling a go myself, but cant find your tut on building for the 6800; any chance it still works for lollipop? cheers
[Galaxy Tab 7.7 Android Development] prohackerbro:
tester

I'll be there to test the ROM, if you need a tester :) would be really awesome if you would upload this build, you say its pretty stable, so if you want to... :)
[Galaxy Tab 7.7 Android Development] so_ang:
Just install this ROM
[Galaxy Tab 7.7 Android Development] superalby69:
where I can found a noob guide to flash this ROM, please?
[Galaxy Tab 7.7 Android Development] dfkt_:
Just flash it in CWM or TWRP, and wipe.
[Galaxy Tab 7.7 Android Development] marlar:
I am trying to flash this ROM with Mobile Odin, but I get this warning:

Is this something I should take seriously, or is it safe to proceed anyway?

Have any of you seen this before?
[Galaxy Tab 7.7 Android Development] TBarb169:
I would stop where you are and step away from the tablet. Do you not have TWRP or CWM installed? If you do, then you should just download the zip, boot to recovery, make a back-up, wipe and install. If you don't and are not sure what TWRP or CWM are, then i recommend some reading/research. Odin and Mobile odin are typically not the programs to be flashing Roms with.
[Galaxy Tab 7.7 Android Development] marlar:
Yes, I have CWM and will use that instead.

I have used Mobile Odin several times before without seing this warning, though.

Thanks!
[Galaxy Tab 7.7 Android Development] :
Anyone getting serious lag on this ROM? I just clean installed the latest build, alongside with BasketBuild's Lollipop GApps, and it's lagging like really, every click takes around 15 seconds to 1 minute to complete. It's okay when everything else is closed though. The moment I open an app, say, Play Store, it'll show a white screen and simply freeze there and become really unresponsive.
[Galaxy Tab 7.7 Android Development] p3dboard:
Was this the cm12 rom you are talking about? Otherwise your gapps might be the wrong version
[Galaxy Tab 7.7 Android Development] bassem.mohsen:
thanks a lot for your support, also there's minor bug.

when locking the tab while listening to music, the music results noisy sound (like the current tone is oscillation around the same tone.

and it occurs only when lock screen sound is active from settings.

my analysis for this bug: is that when 2 sounds try to work together, one crash another, or they just can't overlap correctly.

---------

tried the rom for 2 days now, it's very stable, no reboot occurs or anything. i think it's going to be amazing actually.
[Galaxy Tab 7.7 Android Development] m0bster:
Thanks Daniel for keeping this tablet going!

I hope you'll fix bluetooth eventually!!
[Galaxy Tab 7.7 Android Development] GNUDroid:
Cool an update! Thank you Daniel!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Will test and report later when I'm home...

Edit: good one! Already good state now. Backlight and gps fine as stated. Some glitches here and there, mainly the cm gui itself. I have problems with gallery app (quickpic works fine) but that seems to be related to the gapps package....

... more cpu/gpu demand apps like google earth work fine! Already in this bleeding edge stadium seems to be up or faster than cm10.2

Top! Since i ise my tab just for two things: images and casual surfing, already my daily driver now! Thank you daniel!
[Galaxy Tab 7.7 Android Development] deani77:
For art you need odexed version of gapps. You can to search for banks gapps or PA gapps which have art compatible gapps
[Galaxy Tab 7.7 Android Development] GNUDroid:
Did you tested art already l on your tap? Is it more or less working! What is about first performance impression?
[Galaxy Tab 7.7 Android Development] hong25:
Hell yeah.. U are the magical ROM maker. Can't wait to flash your new rom kitkat 4.4 :thumbup:
[Galaxy Tab 7.7 Android Development] deani77:
Tested on my N4, not yet on P6800 since I need some of the features from original firmware. On stock right now after a very long time on PAC ROM.

On N4, I can feel it was smoother than dalvik on stock ROM and Kernel.

Kitkat works perfectly and seems pretty smooth so far. Apart form the "snow" when you change the orientation (didn't have to do anything it worked straight off?) everything works great (apart from the stuff mentioned in the OP obviously).

Thank you.
[Galaxy Tab 7.7 Android Development] gvoima:
Very nice work daniel, thank you! There's still hope for our tab :)

And if samsung really made a worth releasing some source to get a working hwcomposer, as stated here exynos 4 insignal update, there's even more hope!
[Galaxy Tab 7.7 Android Development] bassem.mohsen:
it's really nice, I can try to study difference between used open source HWcomposer and Samsung one.

I will try to get Vsync working in surface flinger.
[Galaxy Tab 7.7 Android Development] pemmoura:
If this really works I will stick with this tablet for a while!
[Galaxy Tab 7.7 Android Development] 11nn93n9:
Nice work. I installed it and found it is quite responsive. In addition to the already listed issues, I found that APN is not populated and I cannot get 3G data flowing. Manually setting the APN fields fails to get saved. I am Phone call works, only not data. Thanks Daniel for your great efforts to this device.
[Galaxy Tab 7.7 Android Development] bassem.mohsen:
it seems actually it works on s3 devices and gained a lot of UI smoothness due to the samsung graphic HAL

[Galaxy Tab 7.7 Android Development] HDRAGON:
really excited ! to C kitkat on 7.7

i almost disapointed to have any other update!

after 1day using,

every thing is smooth and buttery (except cm usual bugs that reported in fist post)

even more buttery than 4.2.2 paranoid rom and its completly obvious that 4.4 version of android builds to give even more performance from slower devices

it says no service,but my MTN simcard works nice and perfect,both sms & call

wifi works perfectly and had no peoblem during my usage

but here comes some problems :

call screen is always in landscape mode

bluetooth hangs on turning on and doesnt work,

and in standby ,i had 6% battery drain on every 4 houres (i had 1% or less per day on stock 4.1.2 rom)

gallery is too slow on loading pictures

video player FC

camera FC when pressing shutter button

looking forward to see your next release and hope 4.4 cm basic problems be fixed very soon :)

thanks
[Galaxy Tab 7.7 Android Development] Alcibiade:
Can anyone confirm he battery drain? I am very interested by the ROM (even f some things don't work) but I need quite some battery life :(
[Galaxy Tab 7.7 Android Development] {Diemex}:
I dont have 3g even though I can call people. If Imopen the browser I have no connection. Data is enabled in settings.
[Galaxy Tab 7.7 Android Development] palexr:
If? There is no "if", it works. At least on the p6810.
[Galaxy Tab 7.7 Android Development] pemmoura:
I was refering to the HWcomposer. The ROM is amazing. The only thing that brothers me is the lack of hwcomposer and vsync due to Samsung proprietary stuff.
[Galaxy Tab 7.7 Android Development] sbkoh-xda:
Anyway to recover from this without wiping data? :p
[Galaxy Tab 7.7 Android Development] Tom2112:
Very cool! Thanks Daniel!
[Galaxy Tab 7.7 Android Development] golfinggino:
Just flashed it and it is running great thanks for the update !!

I never would have thought that this device would be running 4.4 before my phone sony xperia ultra or my 10 inch tablet 2014 galaxy note 10.1
[Galaxy Tab 7.7 Android Development] Nuclear Blast:
Hope keyboard is black, like PAC Man Firmware has?

It`s nice.

Thanks, runs nice, hope 3g data will work in future builds.
[Galaxy Tab 7.7 Android Development] Edwrib:
Do you have any build for p6800 with the new Samsung HAL?
[Galaxy Tab 7.7 Android Development] daniel_hk:
I don't think there is "new" HAL from Samsung. The "latest" official soucre for i9300 was released a few months ago (MJ9, android 4.3). As before, Samsung only release the source of the kernel. The platform inside is an emulator.

The hal drivers are in the project android_hardware_samsung. If you go through it, you will find only a few commits during the past few months. All are minor changes not by Samsung. The latest commit is almost a month ago and have already included.

I study the source of i9300 (and a few devices with similar hardware) all the time. If there is usable part, I would include it.

Again, any suggestion is welcome.;)
[Galaxy Tab 7.7 Android Development] LBN1:
For a couple of the concerns noted above,

My standby rate is fine; dropped 1% in 7 hours. Note, I am using CPU Sleeper, a CPU tuner app with a screen off profile, and my wi-fi turns off with screen off.

Gallery too slow - Work around is to use Quickpick - fast as it typically is.

Video Player - Using Mobo Video Player worked but was a little choppy; then download the Mobo Codecs for ARM7 and it seemed to smooth it out at least in testing; tried several videos and they were ok but did not watch them until the end.

Also to Daniel_HK / OP: I edited my Build prop using some of the well known XDA tweaks for screen smoothness, etc. and they took just fine, and seemed to help in general. Overall the usability is good with your acknowledged problems in Bluetooth and Camera not working yet. Thank you!
[Galaxy Tab 7.7 Android Development] Nuclear Blast:
Daniel, please, tell us when will we be able to use updated version?

Thank you for this BIG WORK!
[Galaxy Tab 7.7 Android Development] daniel_hk:
Not much time for this but I just managed to fix the Camera. I'm working on mobile data now. The old blob is not compatible with the new platform. Seaching for similar source from other devices.Hoping to use an opensource driver like the camera.

Don't have any other big progress and no significant updates in cm11 too. If anything new coming up, I'll release it. ;)
[Galaxy Tab 7.7 Android Development] k2wl:
@daniel_hk

i just saw your device has bluetooth implementation problems due to bluedroid and this device uses csr chip.

my device i8552 galaxy gand win duos also has csr chip.

and i just found out that bluez team released their first android hal release. which can be implemented in android as a bluetooth stack instead of bluedroid.

link http://www.bluez.org

http://git.kernel.org/cgit/bluetooth/bluez.git/tree/android

there is android folder in the source which is used for implementation.

here is what their site said about the release

if you can implement this then it may be useful to me also...i am trying to get jb 4.3 or kitkat on my device.

hope you find this useful. :)

i attached the source below.
[Galaxy Tab 7.7 Android Development] daniel_hk:
Thanks for your info.

I also visit bluez.org once a while.

Bluez support for Android is there since day one (inherent from Linux and stop at 4.2). What they are doing is just the updates, not a new thing.

I had ported bluez to my 4.2.2 roms. If you take a look at my sources (mainly in frameworks base and phone.apk) in github, you would find hundreds of changes across multiple files.

In 4.3 and 4.4, the footprints of bluedroid are everywhere. My approach is most likely not working again.

If you want bluetooth for our chip, in my opinion, you can forget about bluez, almost impossible.

Bluedroid have some services like PM in HAL while bluez implement them in kernel. Rewriting the bluedroid management service and replacing the functions with bluez counterpart might work for 4.2 but not for 4.3 and 4.4.

Writing the bluedroid stack for csr seems the only option left. I don't have enough knowledge and guts to try yet. Actually, no one dare to try yet...

If anyone can make bluez work on 4.3 and 4.4, I would be more than happy to include!
[Galaxy Tab 7.7 Android Development] k2wl:
this source i attached there contains the new bluez stack which can replace bluedroid.

it is seperate HAL you are taking about.

use android folder in the source and read the files there.

actually i am waiting for 4.2.2 for my device.

because for 4.2.2 mostly samsung will implement something complimentry to bluedroid for csr chip.

Does anyone know how could I configure the positions or order of the soft navigation keys at the bottom of screen?
[Galaxy Tab 7.7 Android Development] bassem.mohsen:
why there's no advancement or new builds for CM11 ?

been refreshing the page everyday with nothing new :\

Hope Daniel is OK these days.
[Galaxy Tab 7.7 Android Development] UgloBuglo:
You are free to start contribute your own build to the community right away.

What's stopping you? Perhaps real life, and the fact that you would have to sacrifice a huge amount of your personal free time and get nothing back?

I'm sure that if/when Daniel have something to share he will let us all know.

I could be wrong but I think Daniel stated he was really wanting to work with OmniRom

http://xdaforums.com/showthread.php?t=2535734

and was putting cm 11 on the back burner for now.

I tried both when they first came out and they felt the same to me. I still prefer his cm 10.1 - runs flawless -but will continue to follow his developments as he has time - His efforts are fantastic and I am getting ready to try his 12-11-2013 rom

Can we flash this over 4.4.1 omni ROM without factory reset ?
[Galaxy Tab 7.7 Android Development] daniel_hk:
Some crashes when switching between AOSP (Omni) and CM. It might be annoying.

If you use TWRP, I suggest you backup the data for each ROM. It would be much easier to restore after flashing.

Good luck!

PS. working on the new Omni now...;)
[Galaxy Tab 7.7 Android Development] golfinggino:
Thanks for the reply will just wait for the new omni rom then
[Galaxy Tab 7.7 Android Development] GNUDroid:
switched via dirty flashing from omni ROM to this cm11 build. Working great even with art enabled (to enable it you also have to edit the blocking in the build.prop)!

Still exist:

Glitches at rotating

WiFi can not be disabled permanently
[Galaxy Tab 7.7 Android Development] GalaxyGS:
does gapps works on ART runtime?
[Galaxy Tab 7.7 Android Development] GNUDroid:
Yes. Google for pa gapps packages in the xda forums. There are some which are confirmed by users to be working with ART. I do not remember which I took, but as I said most of the pa gapps should work.

Make a backup before switching to art!

Remove persist.sys.dalvik.vm.lib=libdvm.so from build.prop before!

Reboot and wait a looooooong time (approx 10 min) (first one thinks that boot hangs at the bootscreen)

By the way: has someone an idea why WiFi can not be disabled permanently? May it be an app? (Nowadays even google maps has the permission to switch WiFi on, maybe other google apps also?). Want my router to let WiFi sleep (switch of signal at no connection) over night. But now it won't.
[Galaxy Tab 7.7 Android Development] daniel_hk:
Have you try turning on the Advance wifi options?

scanning always available disable, Wi-Fi optimization enabled.

Wi-Fi will turn off at sleep even if it is set to always on.

WiFi

Another Thing When the WiFi optimization is ON and you close ur tab the WiFi turns OFF but when the WiFi optimization is OFF and you close ur tab the WiFi turns ON
[Galaxy Tab 7.7 Android Development] Nuclear Blast:
Uffff ... A small list of issues / nuances:

1) WiFi in my tab doesn`t work normal - in some situations: after clean instal ( all three wipes ans etc.) if i choose WiFi network during first startup - it`s turning on and of in circle mode, trying to catch WiFi network. If i didn`t choose WiFi network - i can use it after installation, but not stable variant - i think that after reboot i saw again that circle switching on and of...

2) Sometimes. especially after first reboot after install clean firmware, tab hangs - triyed it 3 or 4 times.

4) bugs on screen after|during turning

5) it less smooth on main screen and in menu than PacRom by Daniel

6) graphic problems with font - i couldn`t see any inscriptions on main screens under shortcuts. In menu everything is ok. Changing font`s size didn`t help in this situation... done - problem was in number of lines/rows - only 5 maximum on the screen, long tap on the main screen, settings --->rows/lines. (i don`t how it sounds in english, i am using Tab with Russian)

7) And big problem now - i can`t to downgrade to PacManRom - Eror Situation 7.

8) Strange camera - in the middle of the screen.

Last time it freezed after clean install in CM11...with wipes.... f***k ( i am in panic

But I - reste:

After one more clean install with wipes my Tab have not seen sim-card. I rebooted it three times - the same result. I installed sim card in other device - it`s ok. Again in tab - failed ---> "Check your sim-card"

But i could boot on with new CM and Googles (of course - every time new) via WiFi - without simcard in Tab.

Then - i installed it - and it`s ok...

Strange, very strange firmware.

I am sure that this will be the best work of Daniel, but at the moment - still much to finish. Including - the problems mentioned above.
[Galaxy Tab 7.7 Android Development] MRBR7:
Unfortunatley wifi is switching ON and OFF as mentioned above..

How do I revert back to 4.2.2 Rom?

Im running TWRP 2.6.3.1

Im getting assert failed: getprop("ro.product.device") == "p6800..... blah blah

E:Error executing updater binary in zip...

Just tried flashing a older version of TWRP 2.6.0.0

with odin 3.07

flashed ok but cant get to recovery mode..

edit have flashed new version of TWRP again so have recovery again..

2.6.3.1

will keep tinkering away..

If anybody can help me to get back to 4.2 would be appreciated..
[Galaxy Tab 7.7 Android Development] daniel_hk:
Fistofall, HAPPY NEW YEAR to all of you guys! :)

1. I have no trouble in wifi for 12/28 cm11. Before that mobile data and wifi can not coexist. You may come from a dirty flash.

2. You might have connected to your pc at boot. The new mtp daemon might hang when USB is plug and idle for something. I think its the support for usb3 cause it. Try unplug it when not it use.

3. missing ... ;)

4. already at kwon issue since day one. Don't know why. Suspect new opengl cause that.

5. no comment

6. That is what stock android provides. Some launcher and MOD may change it

7. If you are in TWRP 2.6.3.x or CWM6.0.4.x, you havent read my thread. There is a Note in red at top of the thread. Next time read the thread before flash. I splent time to write them for a reason...

8. Don't know what you mean? Screen shot please.

It requres a clean flash if you have problem with wifi or other hardware. In order to fix the moblile data, the sim initialization is delayed. It may say no sim after a factory reset. Just continue the setup. It will connect after a while (depends on the previous settings). Try to be patient for a few more minute. After the first connect, it would behave normally.

Good luck!

[Galaxy Tab 7.7 Android Development] UgloBuglo:
daniel_hk, could you please explain?

The note in red in first post tells us to use TWRP 2.3.1 or higher, and to me 2.6.3.x is higher than 2.3.1? Yet you say 2.6.3.x is wrong?

I was going to flash this today, but now I'm not sure I dare to try it before I understand....

Anyway, thanks for all your hard work! :)
