[Verizon Samsung Galaxy S 4] Cilraaz:
Since Euroskank has discontinued his nightly CM12.1 builds for the Verizon S4, I've decided to pick up where he left off. These nightly builds will be very similar to what you'd seen from him, as they're essentially CM12.1 nightlies with some interesting cherry picks along the way.

Edit 1/8/16: I am no longer building CM12.1 for jfltevzw. I am now building CM13 instead. I no longer have an S4, however, so I can't even say if the builds are functioning properly. If you'd like to try them and let me know, that would be great. I know I stopped building for a while in late November and December. If you're a user of these builds, I apologize for that, but my work and personal life stopped me from paying attention to building CM.

Latest CM13 Changes Merged: http://review.cyanogenmod.org/#/q/status:merged+branch:cm-13.0

Note that the cherry picks included in my builds are listed on the right-hand side of the page.

In addition to cherry picks from CM's gerrit, I have also included two custom changes:

Hosts file based ad blocking, compiled from several reputable sources online

Specifically: adaway.org, hosts-file.net, and pgl.yoyo.org

The boot animation from the Euroskank builds

Disclaimers:

First and foremost, I am not responsible if any of these nightlies breaks your phone. They are up-to-the-minute (as of compile time) builds with some cherry picks that haven't been completely tested. Things can and will go wrong. You've been warned. Make a backup and know how to recover your phone from situations like boot loops before trying to flash this ROM.

These builds are for the Verizon Galaxy S4 variant (jfltevzw) ONLY. If you flash this build on any other device, it is not guaranteed to work and likely to cause you to have a bad day.

This ROM is CyanogenMod based. It WILL NOT operate on a phone with a bootloader version after MDK. It WILL NOT work with SafeStrap. Do not try.

These builds do not include gapps. CyanogenMod is designed to work independent of the Google applications. If you'd like them, please feel free to download a package from another source.

Please let me know if you have any problems with the website operation or bandwidth (slow downloads, timeouts, etc). My server should be adequate, but I'm unsure how many people may try to download.

While these builds are nightlies, they are not guaranteed to be built on a nightly basis. I am building them manually, so if I am too busy, then a day or two might be missed here or there. I will typically leave the most current build and one or two previous builds on the server. I won't be keeping a long-term history of builds.

I may discontinue these builds at any time. I have upgraded to a Nexus 6 (shamu) and am continuing to build for the S4 at user request. NOTE that I do not have the device any longer, and as such am unable to test any of the builds that I am producing. I produce nearly identical builds for shamu, but different hardware/firmware handles changes differently. I do pay attention to the thread, however, so if cherry picks are made that negatively impact the build, please let me know so I can remove them.

Suggestions and bug reports are welcome. If there are bug reports, I ask that you include as much information as possible and a logcat when able. I reserve the right to ignore any suggestions or bug reports if I feel that they do not warrant attention. I cannot troubleshoot issues if you are using a kernel other than the CM default kernel included in this ROM. Please do not post bug reports if you're using a custom kernel.

Credits/Thanks:

I take no credit for the code that goes into these builds. This is a kang of CyanogenMod. All credit goes to the CyanogenMod team and the wonderful people who contribute code updates to their gerrit.

An extra thanks goes out to Euroskank. I've been using your builds for several years, dating back to my old Galaxy Nexus (toro). They've always been top quality. Thank you for building for the S4 as long as you did.
