* Your warranty is now void.

* We are not responsible for bricked devices, dead SD cards,

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.

Other Issues?

Before posting on this thread, make sure of a few things:

You've utilized the search function of the forums. Nothing irritates me more than lazy people who do not search for an answer before asking or ask the same question over and over again.

If you are the only one having a problem. Boot into recovery, wipe data/factory reset, reflash the rom/gapps and nothing else. Boot up and see if the problem persists.

Make sure your post is relevant to this thread. "I'm having problems rooting/unlocking" is NOT relevant here.

LOGS LOGS LOGS!!!! Use this: SysLog by Tortel

CPU Speed / RAM Size

Intel stores some modem firmware in the OTA's in a file labeled "ifwi.zip"
