[ROM][UNOFFICIAL][KitKat 4.4.4][SM-T530NU] CyanogenMod 11 [04/26/2015]

[starlightknight]

CyanogenMod is a free, community built, aftermarket firmware distribution of Android 4.4 (KK), which is designed to increase performance and reliability over stock Android for your device.

------------THIS IS AN UNOFFICIAL UNSUPPORTED BUILD-----------

This is my attempt at porting CyanogenMod 11 to the Galaxy Tab 4 10.1. I use a SM-T530NU, so that is the only device I have tested.

Any other device variations have not been tested and are at your own risk. I will not be able to support other variations as I don't own them for testing.

Special thanks to MetaIIica - I have been using his Alpha build of PAC-ROM KitKat since December. I studied the code for that, along with stock and some other ROMs before starting this port. This is my first time doing any work with Android, so I'm not sure if I'm technically doing things correctly or not.

I know CyanogenMod 12 is under development already, but I have decided to do a CM11 based build in hopes of a making a stable daily driver offering. I have fixed many of the issues present that were present in the PAC-ROM build. They can probably be backported to PAC-ROM easily if its built with my tree, but I prefer the plain CM-based offering myself.

You may get the source of my changes for this ROM on my github. If you'd like to help and submit a patch, feel free to open a pull request. You will of course be credited accordingly.

See below for instructions, what's working, and issues I fixed over the PAC-ROM Alpha.

For any bug reports or feature requests, please use the appropriate tabs at the top of the thread. Please include as much information as possible and if possible a logcat or other debug information in the case of bugs. Requests for supporting other device variations will not be honored - sorry,

Feedback and constructive criticism is always appreciated. I hope you enjoy using the ROM; if you use the ROM, please consider leaving a thanks, rating, and/or review

INSTRUCTIONS
- Install PhilZ Touch Recovery (recommended)
- Copy CM11 & GAPPS (Optional) ZIPs to your SDCard
- Boot into Recovery
- Do "Clean to Install a New ROM" (FULL WIPE REQUIRED INCLUDING SYSTEM, NOT JUST DATA/CACHE - even if coming from another CM-based ROM, as my device tree is different)
- Flash CM11 ZIP
- Flash GApps zip from SDCard
- Reboot

UPGRADING
-In general, you should be able to just flash over the previous build, but if you encounter any weird issues please clean using the steps above

Working that I've tested:

Audio: Speakers, Headphones, Bluetooth
Bluetooth
CIFS/NFS (Network File Systems - see notes below)
Front Camera
GPS
IR Blaster [SM-T530NU Only]
Magnetic Cover Sleep/Wake
MTP
Rear Camera
USB OTG
Video (w/ Hardware Decoding)
WiFi (2.4ghz & 5ghz)

NOTE ON BUTTONS: This ROM is configured to use the hardware buttons-- so you won't see the software buttons taking up space at the bottom of the screen, as they are disabled. This is not a bug. Use the hardware buttons, as they are the same. If you really want the software buttons for some reason, edit /system/build.prop, change qemu.hw.mainkeys to 0, save, and reboot. If you map the menu button to a long press of another button, some apps such as TitaniumBackup will count this as a hardware key and hide their soft menu button - but only after a reboot.

NOTE ON CIFS/NFS: Many of the mounting utilities on the play store are outdated and broken due to changes in the linux kernel. For best luck, mount using the command line. For CIFS, you can tweak CIFSManager into working - see this thread

CHANGELOG:

[04/26/2015]
-Fix reading MAC address from EFS
-Fix suspending charging while the device is off (special thanks to @sub77 for pointing out the right config option)

[04/20/2015]
-Enable physical keyboard menu for use with BT/USB keyboards. Auto hides soft keyboard & allows selection of layout.

[04/19/2015]
-Add support for magnetic cover sleep/wake

[04/07/2015]
-Roll back to using the Non-CAF Display HAL Fixes SurfaceFlinger constantly eating 100% CPU

[04/05/2015]
-Fix issues with reconnecting Bluetooth Devices after a reboot (if upgrading, break pairing and re-pair all devices)
-Fix mounting /efs
-Fix persistant Bluetooth MAC Address

[04/04/2015]
-Fix issues with detecting whether or not the device has a hardware menu button.

[04/03/2015]
-Fix the Time Service, allowing Date & Time to persist during a reboot without a wifi connection. Special Thanks: sub77 for pointing the discussion in the thread in the right direciton on this

[03/29/2015]
-Support Bluetooth Audio & AVRCP
-Support Consumer IR [SM-T530NU Only]
-Upgrade Display HAL to CAF Version
-Misc Bugfixes and Cleanup

[03/24/2015]
-Fix Missing Sensors HAL (Fixes Autorotate regression from the last build)

Congratulations ! :good:

 

[vixsandlee]

Nice ROM, it installed fine on my T530 will test some more, thanks for the hard work

 

[steve30x]

I got this installed but the back button and recents button didn't work at all. Its a fast rom though but it would be nice if it was a barebones CyanogenMod without the Pac Rom extras installed too.

 

[pirulazul]

Time for a new test, i'll test it in my t530 and report back the results.

It is a pure Cyanogenmod without the Pac extras. If you're seeing them, make sure you did a full wipe before flashing as noted in the original post - you may have remnants of PAC-ROM in /system. The best way is to use PhilZ option to "Clean to Install a new ROM" as that wipes everything correctly. That could also be causing your issues with the back button as well. I completely rebuilt the device tree for this rom over the pac build, as that was based on MSM8974 when this is an MSM8226 device. If a full wipe wasn't done, you have stuff for the other device tree in /system that will mess things up. If the issue persists after a full wipe, please let me know what varient of 530 you're using, and pastebin a logcat of what happens when you press the back or recent events buttons.

I always completely wipe everything before installing a new rom. Never wiping the tablet before installing a new rom might cause problems. I no longer have the rom installed. I will install it again and see if it was just a flike that it didnt work properly the last time. I also have Philz recovery installed because its the only one that has full brightness on the screen.

Simply great. Everything i need works great. Finally a kitkat aosp rom that given me everything i need. Flashed in TWRP on a t530 (wifi only) and running perfectly fine. Good job mate. If you want me to test anything on t530 just tell me.
Btw, otg works, so my usb keyboard is working.
Otg works, YouTube and twitch.tv works, BT works, rotation works, camera works, xposed works, everything i have tested works

Thanks! Glad to hear that it is working well for you. I believe the only difference between the SM-T530 and the SM-T530NU is the the NU has an IR blaster, which I haven't actually enabled yet. I need to figure out how to test that because I never use it. After i do that and post a build with IR, it will be useful if you check and make sure it doesn't break the regular 530. Those two from what I can tell are vary similar, its more of any celluar varients that I would be worried about, because this is build for wifi only..

Let me know if you find anything broken

I got this to work properly. I have one question though. Is there a way to get youtube working without having all the other GAPPS rubbish installed. I noticed that the tablet got slower as soon as I installed GAPPS. The tablet flies along without GAPPS installed and I only want youtube working without all that other rubbish bogging down the tablet.

Glad its working for you now

To be honest, I'm not sure - you could try copying the Youtube APK off of the device and then side-loading it on a fresh install without installing all of GAPPs, but I'm not sure if that will just prompt you to install all of them or not if you do that.

Are there particular use cases you are noticing are slower? I did not really notice any difference with or without GAPPs, other than the initial boot time as they were unpacked and installed. If there are particular situations that cause this, then we could dump some logs to see if there is something that could or needs to be optimized.

I have youtube backed up with all my other apps with Titanium Backup and when I try running youtube without GAPPS it fails and a popup states Youtube has failed to start (or something similar) and if I install the GAPPS I have which is older than the version that is needed it tells me that google needs to be updated. So then I update that and tried freezing the google apps I dont want or use but youtube fails.

The whole tablet is slightly slower with GAPPS installed. I've opened a gapps zip with WINRAR and removed some of what I dont want and only left whats needed for play store to run so it improved a bit.

Hi,

I didn't try it for now...
But thanks for the good work!!

For the Gapps, have you try PAGapps?
It has different package with a lot of options.
The smallest one should be around 136Mo. You can also remove some apk with a config file.
All other apps are available on Play Store...

The GAPPS package I modded is only 76MB. Its just the bare essentials

I used an aroma based gapps. You can install only what you need. About using YouTube without gapps, i dont know if tubemate could do the trick. Use aptoide to install it if you dont like play store. Here is the link for the aroma gapps: http://forum.xda-developers.com/showthread.php?t=2547250

It has something to do with the lighting detection or some other initial initialization that I haven't figured out yet, but as a workaround if you toggle between camcorder mode and back it'll brighten up.

Tested and working fine. Is a nice workaround. I dont mind about this bug as I only use front camera for Skype and such things, but im glad this workaround is pretty easy and fast

[starlightknight]

Hi Everyone,
I updated the original post with a new build. This build should fix the lighting issues with the rear camera the first time it is used. After I debugged the mode switching with logcat I was able to find out what the issue was. I also am working on reducing dependencies on vendor libs where possible by getting more of the modules that can be built from source building from source.

I've started exploring IR blaster support for NU users and I am continuing to look for a solution for bluetooth audio, but I don't have either yet. Stay tuned for future updates

If you already installed the ROM most times you should be able to flash over it, but if you see anything weird after, try wiping to confirm if its a bug or weirdness after upgrading (you can always nandroid before wiping if you're unsure and roll back if its not related to upgrading).

Please let me know if you find any issues. Include model number and if possible a logcat as well.

Enjoy!

Congrats starlightknight!

Anyone tried this on the SM-T530?
