This is incredible work!

I'll flash this evening and reply back.

Thank you for all of your efforts here!

No problem! I'm glad to contribute. :D

There are some issues of course like camera not working and microphone but on the majority of it works well.

Please do check if Google Play downloads apps properly! ;)

Thanks! :D

Great Progress

Shaheer, your teamwork with Valera1978 have brought a fantastic improvement to this ROM in just a few days.

Most things are currently working:
- Bluetooth
- External SD Access (use SD KitKat Fixer for initiatial run)
- Root
- Google Play (Market)
- Stereo Sound
- Sync
- WiFi (though you need to manually login after reboot, R4 fix is not working)
- Cromecast (full screen transfer with #MirrorEnabler hack)
- init.d support (need installation)
- Text-to-speech
- Downloads
- Recent apps button (in navigation panel)

currently not working:
- PC mount (I tried everything I could think of - no go)
- Camera (causes system to crash - don't use)
- Screenshots
- Torch (Flashlight)
- GPS lock (can't get GPS lock, though works over WiFi, and I can't tell about voice guidance in Google Maps)
- Microphone (recording apps crash)
- Xposed Installer (att. causes black screen and will eventually crash, but you can still get it to work by insisting, I'm currently running about 15 MOD's - but it's a real hazzle at every new flash)

If there is a way to get the PC-mount to work, it would significantly help as the T900 is incredibly slow to wipe and format. To go from cm11 to stock and back to cm11 is a 45 min process, and this just to download and re-flash an update...But, you could of course use Google Drive or DropBox.

However, as I earlier stated, I'm really impressed of what it already can do, notably as this was done w/o access to a T900. Thanks a lot for all your efforts.

WOW! Thanks for the great list of things working & not working! :highfive:
About the Wifi not remembering password upon reboot, i've never had that on the CM for my Tab Pro 10.1. Will look into it! :good:

Thank You!

You're welcome. I've added a few more items to the list
The cm11 ROM is very light weight, just about an eight (1/8) of the stock touchwiz ROM, 226M to download and another 25M for a mini GApps. Boot time seens to be 3- 4x faster, and this feeling continues while running the ROM, everything mounts so much faster. Overall it's very smooth and responsive.
As soon as the PC mount is fixed, this will be a breeze, but it's already indespensible. Besides, I can always use DropBox, or Google Drive for file transfers.

Yeah, CM does seem faster than touchwiz doesn't it. Not always the case though, I tend to like touchwiz better but sometimes it gets on my nerves too. ;)
R4 is literally almost done uploading in 10 seconds then i'll add the link to the OP. :highfive:

If I could just get camera and PC Mount working :confused:

1st try with R4 was not successfull

Alright, R4 is uploaded and link is posted in the OP. Enjoy! :p

PS: Please read the changlog in the OP and please check if Wi-Fi remembers password after rebooting

In R4, the WiFi connection is actually slightly worse than it was. At times it states disabled and you need to turn off Wifi and turn it on again and, bien entendu, manually enter your credentials again. Additionally, you still lose connection on almost every reboot. The same issue exist with the T-520 ROM, see posts #; 42, 43 and 112 in the T-520 forum.

However, the built in init.d support, SD Fix as well as the recent apps button all work well.

Additionally, I can confirm that there is no GPS lock.

I also installed Jeeko's MOD PurePerformances X and I'm at least under the impression that it runs even smoother now...
Anther alternative would be to try PMB Nitro X, but there was no uninstaller, or JustArchi's ArchiDroid Optimizations, but I couldn't figure out how to deploy it at 5am...
I also opted to install ViPER4Android Audio Effects in order to improve the sound in comparison with the built in DSP Manager.

When I get time, I will suggest a comprehensible list of tweaks, MOD's and tools, that will improve your performance, or make it a more enjoyable working environment. But, for the moment I need to concentrate on my upcoming final exam (9/27), and on getting a job thereafter. Once screenshots are working it will make more sense.

What's different between the camera used in the T525 and T520?
Wouldn't it be possible to port over crpalmer's "SM-T525 cm11.0 LTE" - (picassolte) camera to the T520, and maybe also some of the other broken parts?
Are there more things than the LTE capability that are different?

If the port from T525 to T520 works, it might also be possible to use in the T900...

Have you had any contact with crpalmer?
It seems like he has ordered a T520, and was interested in working on an Exynos based device.
I just ordered one. Seems like as good a time as any to see what it's like to work on an Exynos based device.

Wouldn't it be nice to get a AOSP kernel to go with this ROM?

LibiSC's LibidinosoSC kernel for touchwiz T520 was a first break-though.

I hope that now when we have close to complete AOSP ROM's for the Exynos based devices. It would be nice to take a next step with one for cm11. Maybe, a fully working kernel could even solve some of the outstanding issues with the T520 and the T900 versions, it seems like LibiSC got some of this done with his kernel.

You never get too old for dreaming...or playing...

GPS fix from T-520 not working

GPS fix. Should work GPS and GLONASS.

Relpace all files from attach to CM11_SMT520PortR4.zip and flash it.
Or you can manually copy\replace it using es explorer or root explorer.
But in this case please check rights:
gpsd: -rwxr-xr-x
gps.default.so: -rw-r-r-

I ported the GPS fix to the T-900 ROM, but it did not work. I spent about 3/4 of an hour under open sky. I re-placed the files according to instructions, as;
system/bin/gpsd rwxr-xr-x
system/etc/gps.xml rw-r--r--
system/etc/gps.conf rw-r--r--
system/lib/hw/gps.default.so rw-r--r--

Unfortunately, I had no GPS lock, what-so-ever. I also tried applying the various "gps.conf" found in the "perfect solution" threads at XDA, but non of them succeeded in getting a lock, using GPS Status Pro
I'm sorry, but at least I tried my best...

What's different between the camera used in the T525 and T520? etc.

Apparently it wasn't as easy as I thought, crpalmer explained that the cores are completely different between the T-525 and the T-520, one is qualcom, while the other is Exynos based. Apparently they are not at all compatible. Well, back to the drawing board...

We would really appreciate your help in participating in the creation of cm11 T-900

I didn't get to it lastnight, but this is on my list for this weekend, without a doubt. Heading to a wedding/reception shortly that will last (hopefully) well into the night!

I was researching the best way to root the tablet. Seems there is still no way to root w/o tripping the KNOX flag, correct?
If not, I assume the steps at this the following thread are all that's needed?

Finally!

Thanks for all your hard work! Looking back at the thread you seem to be on your game regarding bug fixing.

About to take the plunge myself but wanted to ask the guys who have already flashed it.

I use my tablet all the time. Would you recommend R3 or R4 as a daily driver?

    Sometimes a day seems so long...

    Lol. Sorry ;) My uncle who I haven't seen in 6 years surprised us on friday (when I was going to work on the ROM) that he's visiting us. So i've been all caught up in that. Also I'm trying to port over the Galaxy Tab Pro 10.1 CM Build over since that is more like our tablet. I'm really trying to spend most of my time with my uncle cause he's here for only a week. But i'll try to get it uploaded soon. Thanks for understanding. :angel:
