Congratulations on being official

It's with great interest I have followed the development of your T-520 version of the cm11, even though I don't have one myself. Why? Firstly, I'm amazed by the short time frame in which you actually accomplished this, and conquered the Exynos SoC. But, I'm also A proud owner of a T-900, and from what I can tell there is only the screen size that differs the T-520 from the T-900. In my mind, it should be feasible to port, though I might be wrong.... Maybe, you have some ideas of how to correct/evolve Shaheen's port of your ROM. Who knows, maybe at this point you're bored and need a new challenge, as the major obstacle is breached;) and, before the work with Android L begins... Besides, neither Shaheen, nor you own a T-900, why this should be a very simple task:laugh:
The current error report is as follows:

Thanks for reviving this one Shaheer,

After some problems in getting the full ROM onto the drive (all on my side), I finally got it up and working. The ROM is a lot snappier that prior versions, and is stable over all. Below is my summary of working/non-working functions. Additionally, with the all new TWRP 2.8.0.0, see post #55, the format of system and cache are instant, why ROM testing is a breeze.

I have noticed the following issues:
- WiFi connects, but loses password on reboot, same issue as earlier build
- Bluetooth: devices are seen, but do not connect - Error message: Can't connect
- External SD is not detected by device - see post #54, below, for more detailed info
- mtp - device does not mount on PC
- adb - device does not mount on PC
- Camera is broken - Error message
- Torch is broken - Error message
- Lid sensor - No reaction
- Capacitive lights - No reaction
- Sensors - No reaction
- IR blaster - No reaction
- Offmode charging - but it will not work on the picasso-wifi either, at least until tomorrow, 20140926
- Home button doesn't work correctly. It wakes up the device, but does not go to the home-screen
- Battery drain is significant - However, it might be my impression from heavy use of the screen while testing

Only two outstanding items (non-tested) from the list Shaheer posted below. I would appreciate if someone would test them and confirm if they are working, or not:
- Miracast displays - Most likely functional, given that the Chromecast dongle is working | Best Guess: yes
- Google Play Movies: downloading a video and then playing the downloaded copy. Apparently, crpalmer has received a CyanogenMod commit and the issue is fixed as of now, 20140925 | Best Guess: No

Anyhow, we (T-900 owners) would really appreciate your input, and I believe speaking for Shaheer as well, and to tap into your substantial knowledge and experience.
Once again, I'm really impressed by your accomplishments, and I sincerely congratulate you to the well deserved status as an officially recognized cm-developer.
Finally, if a tester is needed, I'll be around.
Thanks in advance.

I am so thrilled to see official CM support for Galaxy Tab PRO 10.1. Ordered mine couple of days.. and still in transit. They day I ordered.. I am thinking how will i live with touchwhiz..

I guess now i don't have to worry.. will root and flash right away once its here. Looks like everything is working. I don't care about small bugs if battery life is as good as stock

Thanks again

Good work !

I am on GraveD stock ROM, running very well for a month.
But I plan to try CM11 asap.

If you want to disable the soft buttons and use the on-screen buttons (I use the tablet a lot in portrait mode and the soft buttons get in the way all the time).

1. Enable soft keys : edit the /system/build.prop file to include the following line qemu.hw.mainkeys=0
2. Disable the soft keys : edit the system/usr/keylayout/sec_touchscreen.kl file and add # in front of the two lines
3. Turn buttons light off : go to settings -> buttons and disable backlight
4. Reboot

I don't think it was posted all in one place before.

@crpalmer,

I followed the instructions "How To Build CyanogenMod Android for Samsung Galaxy Tab Pro 10.1 Wi-Fi ("picassowifi")" (http://wiki.cyanogenmod.org/w/Build_for_picassowifi).

I faced issues with drmserver and gpsd on extract-files.sh : "Permission Denied"

I managed this by copying them to internal memory and them adb pull to their destination locations.

It's compiling now...

Hmmmm. That's a good one. Very few vendor blobs tend to have restricted read permissions but apparently we hit two of them. I assume that it was actually drmserver.samsung though right? That's important if your build is going to have working DRM.

I made myself a note to figure out how to make that work better and/or document it better.

FYI, you can also download an existing build, unzip that file somewhere, and then run

./extract-files.sh /path-that-you-unznipped-to/

and it will pull all the files from that unzipped directory.

Hello,

Thanks.

Unfortunately, I need more RAM, only 2 GB RAM and 2 GB Swap don't fit the load.

Did you get Infra Red ever to work? I use Touchsquid and it always worked with every ROM i tried.
But in CM11 it looks like it is broken. Maybe I am too impatient and i should wait a bit for CM to get IR working and go back to GraveD's ROM for a while.
Thanks for the hard work crpalmer!

    A quick update on cm-12.0...

    This has been a total ***** to get up and running, but I finally have cm-12 running on our sm-t520. I would be surprised if we make the first round of nightlies as the fix that I had to make to get the display (and touchscreen) working is in one of the most fundamental pieces of code for getting android to run. But, the good news is that it is now booting and we will eventually get getting cm-12 (either official after I figure out how to get my change merged or some other way to work around the problem, or unofficial when that proves to be too hard). I'm not seeing anything broken that is now a show stopper (the display was potentially a show-stopper because without the right vendor blobs, some things are unfixable).

    OK! Where and when will be still being worked CM12 for picassowifi? That is the question!

    It took me 2 weeks for figure out why the device didn't boot, another week or so to figure a way to make it boot that wouldn't require a dangerous commit that would never be merged into cyanogenmod.

    Sorry, that's not fast enough for you.

    You'll get a build when I think it's at a reasonable point.

    The next nightly (today if it gets built) contains a completely redone interactive cpufreq governor.

    Ideally, this should fix the device getting hot when playing youtube videos and generally improve battery life when actually using the tablet.

    Let me know if you notice anything different/bad/wonky after this change.

    Today's nightly fixes the playback of saved videos in Google Play Movies. That was the only problem that I know about.

    It is likely to not get included in the M11 release as the fix may end up breaking another device (which I don't own and therefore it depends on someone else verifying it and/or fixing it on that device).
