I am creating this thread as a place to discuss development of unofficial CM13 builds for the T31x devices. Those of you that have been around here for a while already know that I tend to get busy with other stuff and disappear a times. So, with that said, if you would like to contribute to the development of this rom, please feel free to do so. I can make you a contributor and you will have the ability to modify this OP as required.

What Doesn't Work:
- Bluetooth has audio issues
- External SDCard will not work as "internal" storage


INSTALLATION

- Make sure you're running latest TWRP 3.0.2-0
- Copy GApps and CM ZIPs to your internal or external SDCard
- Boot into Recovery
- Perform WIPE:
  • In TWRP, select Wipe --> Advanced Wipe.
  • Check Dalvik/ART Cache, System, Cache, and Data
  • Swipe to Wipe
- Flash CM zip
- Flash GApps zip
- Reboot

Updating to a newer version of THIS rom ("dirty" flash)
- Boot into Recovery
- Flash CM zip (no need to re-flash gapps or wipe anything)
- Reboot

If you have any issues after doing a "dirty" flash, do a clean install before reporting any problems.


Downloads
CyanogenMod
Builds: https://www.androidfilehost.com/?w=files&flid=44848

Google Apps
OpenGapps: http://opengapps.org (use an ARM, 6.0 zip) - now on tap needs mini or higher.
HEADS UP: Be sure you flash the gapps package when flashing your rom. If you boot your rom, then try to flash gapps later, you will have issues.



CHANGELOG
For a list of CM changes, you can review the i9300 nightly changelog located HERE.
The i9300 is a similar platform to ours, so most of what is listed there will be applicable for us, unless it is i9300 device specific.


SCREENSHOTS

Tips:

  • If you flash a gapps package and get a force close on the keyboard, boot into TWRP, mount system, then choose the file manager option and delete /system/lib/libjni_latinimegoogle.so Fixed

  • You will need to give your browser permission to access storage before you can download anything with it. Go to Settings-Apps to adjust permissions.

  • If you flash a Gapps package with Google Camera, the camera may not work. Many i9300 users are reporting that the new Google Camera needs an API that we do not have and therefore will not work.

  • When connecting the tablet to a computer to transfer files, it will always initially be in "Charging" mode and you will need to select "File Transfer" mode by clicking on the notification on the tablet.

  • Camera - If you get "can't connect to camera" message, download Mediaserver Killer app from store and use it.

  • Netflix - If you get lines in your Netflix video, edit your data usage settings on the Netflix website to Low or Medium. I created a "mobile" profile and set the data usage to "low"; then selected that profile in the app and I no longer get the lines on the videos.

  • Google Movies - If you get a "license error", you need to give the Google Movies app permission to access "phone"; then reboot.

    I have noticed that the latest version of Google Movies does not work (at least on my T310). It always gives the "failed to fetch license" error when trying to play purchased movies. I found this same problem when I first starting using CM13, but it could be solved then by giving the app permission to access "phone" in the permission settings for that app (then reboot). But, the newest version of the Google Movies and TV app does not request these permissions, so the "fix" for the previous version does not work.

    If you want to use Google Movies and TV app, you can install the previous version (3.10.10) and allow the required permissions (then reboot) to get it working again.

    I will not post the apk because people have varying ideas about installing apps that are not installed directly from the app store, but you can find the previous app on APK Mirror website.

Source Info

What I used to build CM13:

Please don't ask how to setup a build environment in this thread. There are plenty of guides that will instruct you how to setup a build environment for CM. I will not repeat those instructions, only give you the additional info required for building for our devices.

In addition to the full repo of CM13 sources, I used the following from my git:
lt01-common device tree
lt01wifi device tree
lt013g device tree
lt01lte device tree
smdk4x12 kernel source
proprietary vendor blobs

I also used from CM sources:
smdk4412-common device tree
Samsung Service Mode
Samsung Hardware

Will test on the t310 as soon as I can :D I am especially anxious of the Bluetooth headset problem that was evident during 12.X (and other custom roms)
Edit: Tried it out. Bluetooth is still a bit messy for headsets. Unless I am very close (less than 2 meters) - so far.
Edit2: Welcome Back Gr8Nole - missed you (for Dev reasons) :D

Great job gr8nole. One problem that I encounter that is found on lollipop too is YouTube having lag. I really like to use it but in lollipop and marshmallow there's still problems. Still, thanks a lot for keeping this device up-to-date with the latest version of android. Thank you! ?☺?

    Ok guys...good news! I finally got the full CM14 repo to sync yesterday and completed a build last night.

    Have NOT had a chance to test it yet. If it boots, I'll let you guys know. Don't get your hopes up, it's still very early in the process.

    Ok folks, I have working wifi on CM14 now. I will create a CM14 thread in a few days, as I will most likely not have time tonight or tomorrow.

    Edit: Actually, I think I'm going to try and sync CM14.1 since it looks like they have already moved to it.
