I’m not going to develop this ROM any more. It takes too much time, and my phone is about to die, which means I’ll be getting a new one. Also, Android 5+ runs too slowly on this hardware. That’s why I’m currently using CyanogenMod 11 (which is back up at download.cyanogenmod.org). I advise you do the same. All changes I made are available on my GitHub.
Hi everybody! After building MultiROM and TWRP for my device, I finally managed to build CyanogenMod 12! 🙂
My work is the continuation of jt1134’s. It’s basically his work. The things I had to fix (I still have to upload them :/ ) are very irrelevant compared to his work, for which I thank him.
Before you get to the downloads, please read the whole post. Thank you!
Some models are compatible, however, like the SGH-I437P.
* Your warranty is now void.
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.
CyanogenMod is a free, community built, aftermarket firmware distribution of Android 5.0 (Lollipop), which is designed to increase performance and reliability over stock Android for your device.
CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.
All the source code for CyanogenMod is available in the CyanogenMod Github repo. And if you would like to contribute to CyanogenMod, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.

Report bugs in the dedicated XDA thread section. If you don’t have an XDA-Developers forum account, you can still post questions and bug reports in the comments below.
Before reporting a bug, please make sure you are running as stock as possible. This means no custom kernel, no custom framework modification, etc. If you are using any of the above modifications, please flash the rom again to get rid of the modifications before reporting.
REPORT BUGS IN THE XDA BUG TRACKER OR IN THE COMMENTS BELOW ONLY!
- Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you’re doing.)
- If it is a random reboot, grab /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. The following is a useful format to follow.
