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 :D

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

It's amazing what you have done to our poor 6800 with limited support, that is very difficult to upgrade to Android 4.4 even for Google to do it for Nexus 4, really appreciate your hard work very much!!!

I'm getting an error while flashing gapps on p6800.

But i can use my tablet, i'm not sure what is missing.
[Galaxy Tab 7.7 Android Development] bassem.mohsen:
download gapps for KitKat 4.4 from the link provided in OP, basically it's Paranoid Android GApps.

do full wipe before, then flash it.

it worked normally for me.
[Galaxy Tab 7.7 Android Development] mashie saldana:
I'm glad to see the 4.4 development on the good old 6800, I will give it a try once the main bugs are fixed.
[Galaxy Tab 7.7 Android Development] GNUDroid:
Hey.

Installed since 1 day now. Had troubles with the gapps download links (2 broken downloads). Now everything works fine after finding another gaps package.

Yea cm11 some features missing but suprised good state already. I would suggest same speed as the last cm10.2 build. Great base to start from!

Actually i like the short "snow" flickering (bug) when rotating or on some transitions. ?

Sorry, i had typed the wrong file name, its the audio_policy.conf, not audio_config.xml. I have updated my post above. The file lives in /system/etc. So if you put it in /etc, that's the wrong location.

Sorry for the confusion.

[Galaxy Tab 7.7 Android Development] xaadilhx:
I really enjoyed using this, performance was good, looks good, themes etc, Google services were fine. There were a few odd reboots, sometimes got stuck, as I changed more settings the stability decreased, viber and Google play services started draining battery. 8 hours of no use overnight and battery was down by 75%. Have to use another, to many reboots and getting stuck at black screen or cm logo.

Will try new carbon....

8/7/14 - Update

Have been using carbonrom 4.4.4 mod by daniel now since 2nd July updated released. I must suggest everyone try this because so far it hasn't got stuck at boot and is very stable. Whole system including new google apps installed (via minimal gapps) updated.

Battery isn't being randomly drained by any app, wifi, blueooth, mobile functions are working fine, speed and performance is good. I would say install a clean system then gapps and test with your configurations. I use nova launcher, I would say carefully activate added functions and test them, I think its worth saying that if you have all fancy functions and apps active, then you could experience performance issues after all we don't have quad cores.

For the moment I've kept active display off (possibly some issues)

As mentioned there is an auto rotate issue but you can get it working by using specific settings for portrait and landscape.

Sometimes at boot the mobile network can take some time to connect (minor). And sometimes from standby the the tab would reboot to carbonrom screen but hey even the stock rom rebooted at times so its still the best custom rom I've used so far.

really appreciated if you could update your ROM with the latest CM11 M8 which version released on July 08. as CM team said，M8 is more stable version.
[Galaxy Tab 7.7 Android Development] daniel_hk:
I have no problem releasing cm11 first. I had already tried at July 16 with no problem. However, after I sync the source yesterday, it won't boot. Haven't figured out why yet...

Performance

first of all, thx for supporting the Tablet!

everything seems to work fine for me but two things:

everything looks so tiny ..like the navigation buttons and everything

and also..the performance isn't that great, or is it just me? seems to move slow, I thought kitkat would run good on older devices? :(

hoping for a reply and maybe a solution!

It's a nice ROM but too much things in it.

I'm a little bit confuse about all the version :silly:

i815 not functioning with newest cm 11

Hello Big D_hk

Tried the newest omni (last week), but tablet kept crashing or freezing during start up - usually when it asked for google account info. Did not really care with data not working at this time so i just abandoned it. Saw the kernel upgrade here in this cm11 version (got me interested to do a test run) but again I can not get further then google sign in.

checked md5's - did full wipe before install and checked on two diff tabs - although both 815's.

does this replicate on your end???
[Galaxy Tab 7.7 Android Development] fshek:
Tried Slimkat, Omni & prev version of CM on my P6800, but finally back to CM11. The key issue I encounter with all these 4.4.4 rom is sleep to death, and "system cannot boot after power off". Its seems to me that this new CM11 2014.07.27 build is just a little bit better than the old one, but I still experience sleep to death/ boot issue occasionally.

Another issue is color mess up all of a sudden. The blue tone will be suddenly turned off and the entire screen turns to purple color. This condition could be resumed by system root (but re-boot may hang the system).

Anyway just can't believe my old p6800 can be upgraded to run KK, thanks Daniel )3(
[Galaxy Tab 7.7 Android Development] daniel_hk:
Lt.,

Sorry to hear that. I think some tab might have lower tolerance. That's why I included a GPU settings in performance Settings. However, you probably can't reach the settings....

I set the default to 400 which I believed was the max. for mali-400. It works for me and some local friends. Clearly some tabs are not working... I'll lower the default value in subsequent builds.

The new Carbon will have this adjustment. [emoji6]

[MENTION=276970]fshek[/MENTION],

Sometimes when GPU is faster, it might lost sync. Press the pwr button to turn the screen off and on again will resume.

You can also drop the GPU clock in GPU settings.

Good luck!
[Galaxy Tab 7.7 Android Development] fshek:
Thanks, let me try...
[Galaxy Tab 7.7 Android Development] L_o_k_i:
Hi Daniel_hk,

Like fshek I have a color problem with the latest version and I also have sleep of death (I didn't have any of these with the previous version). What can I provide to help you pinpoint the problem?
[Galaxy Tab 7.7 Android Development] daniel_hk:
I think the sleep of death you guys experience is the crash of graphic driver at sleep. The screen would be back but you can connect to adb.

It might be the min. freq. voltage. I O/C min. to 160Mhz from 100 without increasing the voltage. You may increase 25 or 50 mV (or back to 100Mhz) to test.

It might also be the surfaceflinger manager. I'm testing my new Carbon. It works flawlessly.

Anyway, good luck!
[Galaxy Tab 7.7 Android Development] L_o_k_i:
OK, I went back to 100MHz. By the way wifi doesn't sleep when screen is off. I didn't have this problem before (Network notification is uncheck, Keep wifi on during sleep = Only when plugged in, Scanning always available is uncheck).

Could anyone let me know if.......

This version works with 5Ghz networks now (I know other versions haven't)?

The screen layout is 'properly' formatted in both landscape and portrait modes?

I tried a version some time back and remember that the screen DPI was wrong causing problems with some apps and in landscape mode, so I had to go back to stock.

Thanks in advance and I would try it but my tab is my daily driver and I'm using it all the time so can't just test this build without major disruption.

Nova Dock changed location with newest rom

Have installed newest CM11 rom. The Nova launcher dock has changed to run along the bottom side of the tablet no matter if it is in portrait or landscape view. It use to stay on the short side of the tablet no matter portrait or landscape view. Also have newest Carbon installed and on that tablet it still remains on the short side no matter portrait or landscape.

So is there a setting or file that can be modded so that it will stay on the short side of the tablet?

Thanks for any help!
[Galaxy Tab 7.7 Android Development] p3dboard:
I find that this happens when the DPI setting in /system/build.prop is set to 160 (tablet mode), as compared with 182 (the default Daniel has been using in his Roms). It could be another reason, but that's one cause.

dont get fooled GPU vs crashed app

So after about four days of no problems with graphics while set at 400, my screen went pinkish while using chrome. I hit the screen off and then screen back on - still pink?? Tried a second time and the screen was then correct. Three secs later the screen became frozen and I had to hard reset. Opened chrome and again it froze :( Three resets later I decided to use other apps before opening chrome. Everything was going good until I went for chrome - froze. The next time I cleared the cache for chrome first and settings. Chrome tried to open but closed itself. Tried to open again and it closed itself and screen froze. This time I decided to reset my CPU to 1400 and uninstall chrome. Now its back to running great and I have reinstalled chrome beta which is a bit diff for the better then the standard chrome. So it could have just been chrome causing the problems or it could have been the CPU set at 1600 or even a combination of the two. But now for about two hours of continual use I have had no problems. Actually feels faster then before when the CPU was at 1600.

Just saying don't assume its the GPU if your screen goes crazy. I just love electronics!! LOL

Anyone having problems with Cell Standby eating battery life on this build?

I picked up a 'test' P6800 cheap and the battery is getting eaten with minimal usage in just over a day with Cell Standby being the culprit, did a full reset and re-installed ROM to same effect. My daily driver stock version gives me two days of normal/heavy usage usually and I was getting over a week minimal usage when first tested battery.

I should add that 3G is actually turned off as the SIM is not charged.

Stuck in boot loop after returning to stock ROM

Hi Daniel and group,

I tried the CM11 ROM and I really like the direction it is headed, but it is too unstable for me to use as a daily driver on my p6800 device. My device experienced the GPU instability issue with colour changes and black screens constantly. This was happening even after dialling down the clock speed settings. After re-flashing the stock image from SamMobile for a p6800, I now end up stuck in a boot loop.

I can connect to flash the device via ODIN, but each ROM image i have tried ends up in the same situation - an endless loop of Samsung "oval" animation, glowing samsung logo then black screen. It then retries boot until the battery runs out. I can't seem to activate boot to recovery, only a boot to the ODIN flash kernel which lets me connect to ODIN and flash.

I have tried about 3 different versions of the stock ROM from SamMobile, but all have ended in the same boot loop. Anything I can do to get stable stock ROM installed again?

Thanks!
[Galaxy Tab 7.7 Android Development] p3dboard:
The gpu stability is to do with some overclocking settings in the latest build of the rom. If you revert to the previous build you shouldn't have the stability issue. You might need to reflash the recovery image to be able to roll back. I haven't tried to revert to stock. You might want to grab a clockwork mod / twrp flashable .zip file, something like the erobot based roms of you want to go back to Android 4.1.2/Samsung based roms
[Galaxy Tab 7.7 Android Development] xaadilhx:
So your saying you can flash and enter download mode for Odin but not recovery mode for reset?

How do you accomplish this, holding power + volume up or down while device off?

I've experienced these issues sometimes with roms up to August but have always been able change/ revert.

The boot loop lockup Is slightly annoying but I've always been able to interrupt it by holding power button with careful timing. Usually if you connect the charger on the reboot loop then long hold the power button with enough time to power off before the loop restarts then the charger will kick into the charge animation. Of course once you remove the charger the device will switch itself off. At this stage I can always go into recovery mode by holding the appropriate button sequence.

I have found that reverting to the stock after you've have the boot loop issue something is left over in the configuration to cause the loop while trying boot stock. I overcame this simply by entering stock recovery mode and doing a full wipe factory rest.

Everything at that stage loads fine and you may use stock and root/unroot as before.

It's always nice to return to stock because of stability and all the apps work. With nova launcher it runs decent and by using xposed framework I was able to patch all of the known major security issues.

I hope you can overcome this issue, you shouldn't need to continually flash all the time, just factory rest stock. Without knowing the technicalities I just think since the stock and mods use different boot settings, whatever is left over points to the wrong location and this may cause the loop on stock. On at least 2 occasions this year I've overcome this with the factory reset.

Good luck
[Galaxy Tab 7.7 Android Development] engbren:
These pointers did the trick - I got into recovery and did the factory reset and it finally booted! Thanks!

Here are the screenshot on my cm-12.0 (at this stage, it is more or less the same as AOSP). It reboot many times at the Samsung logo before showing the boot animation... However, it is quite stable afterward. Bluetooth and phone are not working yet. It is far from presentable. Still a long way to go...
