This is the successor to my no-frills CM12.1 ROM: http://xdaforums.com/oneplus-one/orig-development/rom-kernel-unofficial-cyanogenmod-12-1-t3120259

Unlike other unofficial CyanogenMod builds, these builds are based off of the stable branch instead of the nightly branch.

Custom kernels are not compatible with this ROM unless otherwise noted. I will NOT provide support if you install a custom kernel.

ROM features:

Based off latest generic CyanogenMod 13.0 stable sources (root access is

NOT

included)

OTA updates via built-in CMUpdater

OxygenOS camera libraries (no camera bugs and improved camera performance)

Snapdragon Camera app by Qualcomm (comes with many unique features, such as high-speed recording with audio)

Custom camera HAL I made myself from CAF featuring:

-Intelligent anti-shake algorithm (significantly reduces motion blur when capturing photos)

-Faster autofocus in low lighting conditions

-No stuttering/frame drops in camera viewfinder (viewfinder frame rate won't go below 30 FPS)

-Slow-motion video recording at 60 FPS, 90 FPS, and 120 FPS for 720p, and 60 FPS for 1080p

-High-speed video recording with audio at 60 FPS, 90 FPS, and 120 FPS for 720p, and 60 FPS for 1080p (you need to use the Snapdragon Camera app in order to use high-speed recording)

-1080p video recording with the front-facing camera

-2.5k 1440p video recording with the front-facing camera and back camera (only with the Snapdragon Camera app that comes with the ROM)

-4k video recording at UHD and DCI resolutions

-Manual focus

-Manual ISO control

-Slow shutter (ranging from 1/5000th of a second to 2 seconds)

-More picture sizes than plain OxygenOS, such as 9.7MP 16:9

Many other misc. improvements under the hood

Kernel features:

Based off latest CAF Marshmallow kernel source from Qualcomm (LA.BF.1.1.3_rb1.13)

Removed lots of excessive bloat

Rewrote battery driver (for the BQ27541 fuel-gauge chip; battery % readings are more accurate, there are various

safety mechanisms now, and you may get better battery life)

Rewrote half of the Synaptics touchscreen driver (over 2500 lines of code modified; your touchscreen may work better)

Newest-available Synaptics touchscreen firmware

Dynamic CPU input boost driver I wrote myself (makes the phone feel smooth without destroying battery life)

CPU underclocked to 1958MHz by default (you can disable this; see why I did this in the FAQ in the 3rd post)

Vibrator is automatically disabled when recording videos (so the buzzing noise doesn't get in the videos)

Custom thermal control driver I wrote myself (features 8 thermal throttle steps; keeps the phone cool)

LCD KCAL by Savoca

Westwood TCP congestion algorithm (enabled by default)

F2FS support

NTFS support

No placebo patches, features, or compiler "optimizations"

Installation instructions (for first-time installation):

First, perform a backup of your existing setup, and then perform a clean install (wipe /data and /system; TWRP is recommended). Next, try flashing the ROM and see if it installs; if it installs without any issues then congratulations! Now just flash a Google apps package, and then reboot.

If you get an error when trying to install ("oppo.verify_trustzone" error), then first you must install/use TWRP recovery 3.0.2-0. Next, download and flash the latest official CM13.0 snapshot. Then, without rebooting from recovery, wipe /system and flash my ROM. This process is necessary to update various firmwares (including TrustZone), as the updated firmware is needed by my ROM. After flashing my ROM, flash a Google apps package, SuperSU

(ONLY v2.65 OR HIGHER)

if you want root access, and then reboot.

Installation instructions (for updating to a newer release):

If you are already running my CM13.0 ROM, then you can update to a newer version of the ROM via the built-in OTA updater or by simply dirty-flashing the new ROM build without wiping anything.

HOWEVER, do NOT reinstall Google Apps after installing a new update.
