This is the cm-12.1 thread. All comments or questions regarding cm-13.0 will be removed.

CyanogenMod is a free, community built, aftermarket firmware distribution of Android 5.1 (Lollipop), which is designed to increase performance and reliability over stock Android for your device.

#include <std_disclaimer.h>

 * Your warranty is now void.
 * We are 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 us for messing up your device, we will laugh at you.

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. You will need to provide your own Google Applications package (gapps). 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 our Gerrit Code Review. Your changelog is whatever was merged into gerrit.


First time flashing CyanogenMod 12.1 your device?
Coming from a SENSE ROM?
  1. Enable all location services: Settings > Location > (all location services) = On
Coming from another ROM?
  1. Download the zip(s).
  2. Install a compatible Recovery
  3. Perform a NANDroid backup of your current ROM (Optional)
  4. Wipe data & cache partitions of your device (required when coming from stock!).
  5. Flash CyanogenMod.
  6. Optional: Install the Google Apps addon package.

What works:
GPS(Get a lock on Sense first)

Doesn't work:
Wi-Fi signal isn't as strong as Sense rom but has become more stable than early builds
GPS you will need to get a lock on Sense first

Looks like data is not currently working. Everything else looks good!

Edit: data started working after a reboot. Text works. When selecting a contact to make a call contacts FC. So far that's all I've noticed.

Runs really smooth on Verizon. The only two issues I found so far were the fc when selecting a contact, as mentioned earlier, and I was unable to send or receive texts.

Thumbs up
Sprint variant is running very smooth. So far the only issue is I can not receive text messages. I can send texts, call and answer calls. Also, the whole selecting contact causes force closures as mentioned above. Connected both my gear live and lg g r with no issues and got an immediate lock with GPS.

Thumbs up Bug
Hi! my first post here on XDA.

A headsup for all those who are coming from CM12..a clean flash is needed as a dirty flash will not allow the new update to boot up.

A small bug found:

Even though I have signal and everything from telephony to data is working fine, the signal bars are showing empty and pull down notification panel shows for emergeny calls only under the Signal toggle..Just an observation..

Flashed the newest build and I'm still having issues with receiving texts. This is on the sprint variant. Is there anything I can do to remedy this? I did a clean install and even tried using messenger and hangouts for texts just in case it was an issue with the default app.
