For anyone that wants to try my test build, I'm learning with Daniel's help (his guide plus feedback) to comiple the cm12.1 rom, I've uploaded my test builds here - https://www.androidfilehost.com/?w=files&flid=37443

This build has Bluetooth working (I just fixed that up with Daniel's help last night). Wifi should be ok, but the Reboot bug with the Es File Explorer transfers is still present.

I only have a p6810 (wifi only model). For that model, I've got a slightly modified /system/build.prop that has the Davlik values the same as my Galaxy S2 CM12.1 nightly (heapsize of 128m and a few other settings).

I've build a P6800 rom, but the RIL component (mobile data) is not included at the moment, as I have errors compiling it (this also has the default Davlik VM values, not my modified ones from the Galaxy s2). But for my Wifi Only model the RIL library is not needed - still if I can figure it out I can help Daniel make new builds of this rom (all 3 models hopefully). I mainly did it as I want to test a change to see if it fixed Asphalt 8 which had graphics issues in the latest CM 12.1 builds for my P6810 (where as the Kitkit rom's didn't), setting the OpenGL ES value to the 2.0 value rather then the 3.0 and for me the game now works fine, no graphics issues on my Wifi model. Another bug I know these builds have is the QS torch tile, turns the light on but can't turn it off.

I am not trying to take over Daniel's job, just trying to be an assistant, plus have the satisfaction of building a Rom for our Device.
[Galaxy Tab 7.7 Android Development] philipnzw:
Hrmm I might have to give your ROM a try

Btw can you list down all the changes to build prop again,like the heap size etc...
[Galaxy Tab 7.7 Android Development] p3dboard:
A Bit more testing - it may have been a residule memory in the Data / Cache of the playstore or google play services, as after adjusting the OpenGL ES setting in /system/build.prop, and clearing the cache during another Rom test (switching between my build and Daniels Omnirom), the incompatible build of Asphalt 8 was no longer offered in the playstore when booting back into Omnirom. Daniel has been trying to tell me that it didn't have anything to do with the Compiling of the rom code, but was just a Build.prop setting, I believe he was right, sorry Daniel :) [MENTION=4948627]daniel_hk[/MENTION] Thanks Daniel for putting up with me :) This was my original reason for wanting to try building a Rom, but I am glad it motivated me to start, now to learning how to be more useful to Daniel

Cann someone help.i have installed the last update for lollipop 5.11 and installed the apps,but i have problem with Youtube,when i open it and sellect a video to play and when it loads it just get out from youtube,what is the problem???
[Galaxy Tab 7.7 Android Development] philipnzw:
Can't play music on latest build ,even tried the omnirom media patch zip ,still not playing,app just crashes

Weird ,anyone having same issues or is it just my thing
[Galaxy Tab 7.7 Android Development] LeonardoD93:
The media player works fine for me,just like i say,i have problem with youtube,and this is my main app,if i cann not fix it i will return to kitkat again :(
[Galaxy Tab 7.7 Android Development] p3dboard:
Have you tried changing the default video playback from Nuplayer to Awesome player in developer settings as our Galaxy tab 7.7 Roms currently still have some issues with Nuplayer, such as seeking in video playback. Awesome player is the old video playback method from Kitkat. To enable developer options, go to settings, about tablet and tap about 6 times on the build number. Awesome player is under Media in developer settings
[Galaxy Tab 7.7 Android Development] LeonardoD93:
...

I have instaled 1 the lollipop from last month and now youtube works,hmhm i dont know,i will maybe try to install again this update from 2 days ago,i hope that your advice will work.
[Galaxy Tab 7.7 Android Development] p3dboard:
I just tried Daniels latest cm 12.1 build and YouTube definitely crashes out for me. Also vlc media player. Mx player works fine, as does the built in video player in Gallery. Daniel is away for a few days, so we probably won't see a fix for this issue in the cm 12.1 build till he is back. Omni rom is working fine if you want to try that rom

Edit: i have attached a log cat of a crash
[Galaxy Tab 7.7 Android Development] daniel_hk:
I have check the log. It was the old permissions issue from Android (You would find a number of reports which Google already noted if you search for "com.google.android.providers.gsf.permission.WRITE_GSERVICES" or READ_GSERVICES too). It appears since 4.3. With some combinations for GoogleServiceFramework (gsf) and location, gsm or account etc., a permission denial would report.

The work around is using an older version of the software (YouTube in this case).

Peter,

The usual and better way to get the log is from a terminal not an apk. And apk would use a service to read the log and write to a file.

I usually use the command:

adb logcat > #filename

in the PC connecting the device. It will dump the log to the file "#filename".

This will ensure the last line of the log to be saved. If the device hang, an apk might not get the full log content.

BTW, I'll be back day after tomorrom.

[Galaxy Tab 7.7 Android Development] hogig:
Daniel,

A request if it is possible to apply; option for us to swap internal memory and external memory upon installation of ROM? Apps such as Magzter, Zinio are my main apps for this device and 16gb internal memory is not enough. I have tried various apps2sd apps. But those apps swears by internal memory... I think the only way is to trick them...

Many thanks.

Hi Daniel.

VLC worked without hardware acceleration in build 27/07. In 27/08 there is no setup possible to make VLC to play the same vídeos 27/07 played fine!

Thanks
[Galaxy Tab 7.7 Android Development] LeonardoD93:
Daniel,when will you release new update,i cann not believe that i have with every ROM problems,first with Kitkat 4.4.4 and now when i updated on lollipop 5.1.1,it go smooth but when i turn Wi-fi it become laggy,especialy when i open chrome,sometimes like 40-60 sec,sometimes freezes and i need to restart,and about 2+ app in same time no wayyyy,on kitkat 4.4.4,when i used some app + fb messenger it worked,but now,it need like 1min to open when i get message,it is so laggy,and i my case,i just wanna to have it to go smooth,when i see the best android was the official 4.0.1 HC.........................sorry for my Eng. i am not so good in writing it :)
[Galaxy Tab 7.7 Android Development] Cluey:
I found some time to poke my tablet, the fstrim app helped and then I've fully formatted it.

Now I've got your OMNI build on it and it is performing very nicely, it reminds me why I liked this tablet so much. :)

Thanks for your continued efforts keeping old devices going.

hi,

Does HDMI out work with this ROM? I have an official adapter which works with my stock rom 100%....want to use this rom but dont want to lose that facility.

thanks in advance

Nick
[Galaxy Tab 7.7 Android Development] daniel_hk:
I'm afraid it won't work. I don't have the HDMI dongle to work on.

I might try but I need someone with the HDMI dongle to test. There will be series of tests which requires a lot of time and patience. ;)
[Galaxy Tab 7.7 Android Development] nk33:
No problem. Use me. I have just installed the rom anyway. Happy to use mine to help myself and anyone else who wants this feature.

I already have a tab pro 8.4 to use everyday anyway.
[Galaxy Tab 7.7 Android Development] p3dboard:
[MENTION=4948627]daniel_hk[/MENTION] [MENTION=1855149]nk33[/MENTION] - i also have a hdmi 30pin dongle, and am happy to help with testing.
[Galaxy Tab 7.7 Android Development] nk33:
Hi Daniel,

I know you are busy but would you like to use our tablets to test HDMI out betas?
[Galaxy Tab 7.7 Android Development] daniel_hk:
Sure, I need some time to finish a job in hand. I might try Andriod 6 first. There are a lot of works ahead and I seldom promise the thing I'm not sure. I might just work on a patch when I'm ready.

It just cross my mind that someone had donated to me to get one over a year ago. There are too many electronic wastes nowadays. I'm just not comfortable to hoard too much wastes. I was thinking to modify a MHL cable which works on other devices too. I had studied a while. I lost the motivation and forgot when too many things were stacked on the table...

I'll PM you when the status change. ;)
[Galaxy Tab 7.7 Android Development] nk33:
ok - but what i dont understand is that the official firmware supported it from the stock rom to all the official updates.- so why doesnt this ROM? Would it take that much time to modify it so it does?
[Galaxy Tab 7.7 Android Development] p3dboard:
We are not using the original mali driver / blob, plus there might be custom source code changes Samsung made for hdmi output. There are a number of possibilities as to why the hdmi support is not working. Samsung stopped supporting our device at Android 4.1.2. Daniel had to backport code to even get Bluetooth going, using a separate Bluetooth stack as the current Android stack doesn't support our older driver, things changed in Android 4.2.

So there's a lot of possible reasons for this. Daniel has done amazing work for our old device.
[Galaxy Tab 7.7 Android Development] tonygamble:
Just a note to say that ten days ago I had never installed a third party rom in my life.

With (mainly) Daniel's help I have converted a stock Samsung 7.7 p6810 to Lollipop, mainly to use a satnav and music centre in my car.

I used it first time yesterday. The satnav logged on far quicker than my original 4.0.4 did and the music seems more responsive. Well worth the effort. Now I want more 'mileage' from my battery and I have every hope that moving to v5 will give me this. I just need to learn more.

I am holding back on Marshmallow until the beta brigade seem more confident about the stability. However, I am confident that with the help of this forum I will be able to install it with ease.

Well done folk. You are a great community.

Does anyone have the original firmware Update Ice Cream Sandwich, for the samsung galaxy tab 7.7 wifi (GT-P6810)?

I successfully downloaded TWRP for Samsung Galaxy Tab 7

used this to WIPE and Install CARBON-5.1.1-UNOFFICIAL-20151201-1322-p6810

and gapps-511-base-20160120-1-signed.

The rom itself is smooth and looks good, until I try to access the Internet or the Play store. I can turn on/off Wifi and connect but the connection is difficult to verify. Should I try "gapps-502-base-20160120-1-signed"?

Any feedback would be appreciated, what did you try that worked for you if you have the7.7 wifi only I have the Hong Kong version

Also I did go to another site for the firmware update because my device recognized the need for one but failed installing OTA, prompted me to use Kies and of course Kies recognized my device when connected via wifi but would not connect via USB cable. I just want to update my device to functionality
[Galaxy Tab 7.7 Android Development] tonygamble:
You seem to be on the wrong thread. This is not for Carbon.

I tried to use the same ROM as you on my p6810 and sent Daniel a log. He said "I'm checking your log now. Seems chromium is the cause. That means the Webview inside my Carbon ROM is not working. "

We tried to fix it with a patch and that does not work. The framework needs changing and there seems to be nobody around willing/wanting to do that. I moved to [ROM][p6800/p6810/i815](6Oct2015)CyanogenMod 12.1 Unofficial and that is what I am posting about on this thread.

It seems that the Carbon team are not working on Marshmallow so I am backing the Cyanogen brand for my progress at the moment.

I got wifi to work but you get stuck when you need to use the inbuilt browser as it does not work.

OK?

Tony
[Galaxy Tab 7.7 Android Development] tonygamble:
I know this thread is effectively dead but, if there is anyone lurking, am I the only on having problems with Chrome?

It must have hung on me about six times yesterday afternoon - forcing a reboot.

I have reverted to the stock Android browser. It seems fine. Am I missing something by not going for Chrome? If so then how do I configure it to work without hanging?

It seems to be the only app that causes problems on this Lollipop.

[Galaxy Tab 7.7 Android Development] funpig:
Hey Molly. I am no expert, but I just managed to flash CM and gapps for the first time yesterday. Suggest you go to the Marshmallow thread for the latest CM 13.0 and the latest discussion and information. I found that I had to use the smallest pico gapp package and I flashed the CM rom + pico gapps (in that order) at the same time BEFORE rebooting. Otherwise, I got a lot of google play services errors.
[Galaxy Tab 7.7 Android Development] Nuclear Blast:
Daniel, hello Master!

How can flash this firmware? Via what version of cwm or twrp?

Are you going to release new/last build of CarbonROM?

[Galaxy Tab 7.7 Android Development] fshek:
Hi Daniel,

You are epic..... I closely follow your release since 4.3 and my device is reborn again, again and again. Today I flash this experimental ROM again on this 2 year old device, and it seems working on every aspect I need.

Can show off to my friend, who just spends about HKD5,000 on a Note 4, that my "old and crappy" device also gets Lollipop 5.0 xDDD

Once again, thank you for your work...

2014.12.03 Update:

- Seems the "close all app" button is not working, the memory will not be released. As a result, the device is getting slower and slower, end up system hang or foreground app FC (?).

- "download in progress" forever in Google Play, even though you got very strong wifi connection. No sure it is write issue or connection issue...

- Switched back to CM 4.4.4, and waiting for stabler version of 5.0 :P

Can i ask which supersu.zip file you used to root? Or how you achieved root? I just flashed the rom on my p6810,and want to restore root and adjust the dpi setting as well.

Daniel - great build for an alpha. I note that the flash light toggle doesn't turn on the flash. Also google text to speech crashes, but picco tts works fine. It might just need an uninstall and reinstall. I assume the micro pa gapps installed the google text to speech.

I think this may have been reported, but only the front camera is working, back camera is just black, no image.

Edit: back camera is working, but as mentioned video capture is an issue. When playing back in MX player, the video is all green.

Edit: never mind i got supersu installed
[Galaxy Tab 7.7 Android Development] ninekaw9:
Tried out 29 Nov 2014 Build. Almost everything in fine, except

- can't play any video.

- can't record video.

- device become extremely sluggish and unresponsive when free ram goes below 100-110 MBs, very high I/O read (around 30 MB/sec) and high mmcqd0 cpu usage all the time until apps that use too much memory are killed
