[Sprint Samsung Galaxy S 4 Android Development] nivron:
The Sprint Galaxy S4 is now receiving official CM 12 builds. This thread is here for reference purposes only. No new unofficial builds will be made.

It seems that the CyanogenMod folks are kicking along pretty well getting Lollipop ready. I was finally able to get a bootable version of CyanogenMod 12 for our phone, the jfltespr. The jflte devices are being de-unified again.

I am building a rather "plain" version, which consists of all merged GitHub items, along with cherry picks that are required to build the ROM.

Disclaimer

This ROM is under development, and the file(s) I provide are a snapshot at a particular point in time. There are no guarantees that they will work. On the other hand, it's quite possible that the file(s) here may make your phone explode, make your boy/girlfriend leave for another country, cause you immense financial loss or other horrible things. I'm not responsible for any of it. I'm just giving you a file. :)

Installation Instructions

Do a nandroid! What happens when the ROM doesn't work??

Use TWRP! CWM has been mentioned to work as well, but I do not personally support it.

Factory Reset! (Wipe Cache/Dalvik/Data)

Install my ROM ZIP file!

Install gapps (PA has Lollipop gapps in ALPHA) (Slim has Lollipop gapps here)

Install SuperSU!

Current Build Info

CM GitHub as of 01/26/15 @ 11:05 AM EST

Cherry Pick: (#79041) - add ANT+ Wireless support

Kernel Source

This ROM is built from CyanogenMod sources. You may retrieve the kernel source here!

What Works / Doesn't

Working: Mobile Data

Working: WiFi - Some users have experienced issues having BT and WiFi on at the same time. One reported fix is to change WiFi to use the 5Ghz channel.

Working: GPS - Some SPH-L720T users have experienced non-functional GPS. I suggest flashing back to TouchWiz and acquiring a GPS lock with GPS Status & Toolbox. Once that happens, go right back to recovery and reflash CM12.

Working: Camera - You may have to exit and go back in before it starts working properly. Also, occasionally the camera will appear to take photos but freeze the preview window and not actually take the photo. Google Camera and other third party apps don't seem to have this problem.

Working: NFC

Somewhat Working: Bluetooth - Some users have experienced slow A2DP playback or issues connecting to devices.

Not Working: Any other potential CM bugs. After all, this is an early release and can be potentially quite buggy.

Not Tested: Anything not mentioned above.

Found Bugs

When plugged in for charging, if you power off the phone, it will reboot after a short period of time. The touchscreen will not be functional. If you hold down the power button to reboot, the phone will be fine.

When using the stock messaging app, SMS messages will show as failed -- but they do go through. I tested to another mobile user and a Google Voice number. MMS doesn't seem to show an error.

Excessive battery drain due to NfcNci.apk in /system/app (reported for the Int'l CM 12 build). You can delete the APK if you experience high battery use from "Miscellaneous". [Hopefully this is fixed in the 11/24 build. Please respond if you notice any improvement]

Location icon stays in the status bar. This happens even if location is turned off.

Home button does not wake device.

I will post new versions of the ROM when I get a chance. New versions will be compiled daily and put into my MEGA folder.
