Information

I present you with Android 6.0.1/CM13 for the Sprint Galaxy S4. This is a WIP, I try to work on it when ever I get a bit of free time.

I will try to post a new weekly build once a week or sooner.

The newest build will be at the top of the downloads list.

Prior to Installation

1) I recommend using and/or upgrading to TWRP 3.0.0 (Install version via 2.8.4 zip, then flash 3.0.0 img to upgrade)

2) Make a complete full backup! I cannot stress this enough! Boot, System, Data, Cache, everything. If for some reason this build doesn't work out for you, no biggie go restore.

3) Full wipe of the system is required (Dalvik/ART Cache, System, Data, Internal Storage, Cache). CM13 is based off android 6.0.1 and is a completely new version requiring a complete new install.

4) Download and have ready in the device's sim card Gapps Version "Arm, 6.0, Pico". (Other variants may work, I have not tested them all)

5) Download and have ready in the device's sim card the new jfltespr CM13 Rom (download below).

Installation

After wipe is fully properly completed...

Reboot in to recovery and go to "Install".

Search for the new Rom.zip where you stored it in the sim and select, DO NOT "Swipe to confirm Flash" at this time, we have to install Gapps first.

BEFORE you swipe, select "Add more Zips" and search for your GappsVersion "Arm, 6.0, Pico" and select.

If you flash the Gapps after the CM install, you will have an error loop so flash during initial install is a necessity.

Now proceed to "Swipe to confirm Flash" and Reboot.

First boot takes some time, but shouldn't take more then 10-15 mins total and progress shouldn't be stalled at any point past 5 mins.

Build Notes

I've noticed that the APN settings are hard to modify. This may change at a later date, but for now it is what it is. If you use an MVNO like do, you will need to flash the APN settings during the rom flash process just like Gapps. I personally have boost mobile and Moped_Ryder has made a very well Boost Mobile zip, though I had to modify slightly with the settings to get LTE working consistently. If you need a zip for your carrier, download the Boost Mobile Zip Ver-2.2 and use notepad++ to edit it to suit your needs.

If you have LTE, but are still having sms issues, install Chomp SMS, it worked right out of the box for me, but you can also set apns manually within the app itself if needed.

Possible bug with Gapps. On my first boot, I installed Gapps Mini and was getting download errors from the play market. I re-flashed with Pico, seems to be working.
