This is an official nightly beta build for the HTC One M8.
HTC One M8 specific bugs:
Credit for making this happen:
1. Download ROM
2. Reboot into recovery
3. Please backup your ROM before you begin!
4. You need a full wipe* if coming from another ROM.
5. Flash the ROM
6. Flash 4.4 Gapps
8. Let it sit a while.
*NOTE: You are more than welcome to dirty-flash (i.e. only wipe cache/dalvik cache) between each of our nightly builds. However, there are times when we push certain changes/updates that WILL cause errors (force closes, etc.) if you choose to dirty-wipe. In such cases, please DO NOT report bugs in this thread until/unless you have done a full wipe (/data and /system) and tried again. If there is any indication of a dirty-flash in your bug report, it will probably be ignored. See my signature for additional information.
