[EOL][OP3T][ROM+KERNEL] Unofficial CyanogenMod 13.0 with custom kernel [Apr 30, 2017]

I've always thought fee ram is just that: unused ram.
I'm curious, because your statement seems to imply free ram is something we want on our devices:
What is an unsed resource good for? Is a max free ram policy (I'm not saying @Sultanxda is following this policy) wasting availible resources? Is sd821's mmu able to poweroff (or at least sleep) not used ram?
Best rom ever, but If i turn on funkction turn off wifi during sleep. After sleep and turn on phone are wifis invisible and i cannot conect. Must turn of and turn on wifi manualy 
after this i can see wifi again and can connect some fix ?
Next thing is, boeffla kernel have anyone this kernel for 3t ?
Kernel works only with LOS 14.1 firmware ...... 14.1 kernel but camera and flashlight are out.

Cannot thank you enough! Bad usb cable problem almost made me insane.
Can't count the hours wasted searching on solutions to my failed installs when the problem was the cable.

This is a unified CyanogenMod 13.0 ROM that works on both the OnePlus 3 and OnePlus 3T. It is based off of the stable CyanogenMod branch instead of the nightly branch, with the main goal being stability with an overall good user experience. This ROM comes with a highly-customized kernel, as well as some other very custom modifications.
Custom kernels are not compatible with this ROM. I will NOT provide support if you install a custom kernel.
Changelogs for each update can be found in the 2nd post of this thread.
ROM features:
- Supports both the OnePlus 3 and OnePlus 3T
- Based off latest CyanogenMod 13.0 stable (ZNH5Y) sources (root access is NOT included)
- OTA updates via built-in CMUpdater
- Fast fingerprint unlock
- Pocket mode for the fingerprint sensor (this is always enabled)
- Improved GPS speed and accuracy
- Custom camera app featuring:
-Photo quality comparable to OxygenOS
-Anti-shake mode (increases the shutter speed to reduce motion blur)
-Manual shutter speed control (1/5000th of a second up to 30 seconds)
-Manual ISO control
-EIS when recording video at resolutions lower than 4k UHD
-Video HDR mode
-Antibanding control
-Exposure control
-Denoise control
-Face detection
-HDR
-Many other manual controls - Many other misc. performance and stability improvements under the hood
Kernel features:
- Rebuilt from the ground up using the latest Snapdragon 821 CAF base from Qualcomm (LA.HB.1.3.2)
- Removed lots of excessive bloat (improves security and performance)
- Improved stability (several bugs not listed here have been fixed)
- F2FS support
- DASH charge
- Passes SafetyNet bootloader unlock check
- Dynamic CPU input boost driver I wrote myself (makes the phone feel smooth without destroying battery life)
- Reduced display power consumption
- Touchscreen gestures are automatically disabled when the proximity sensor is covered
- Improved touchscreen processing latency
- Improved audio jack detection (no more weird buzzing noise and headphones are always detected on the first try)
- CPU underclocked for improved stability and efficiency (big cluster: 2150 MHz LITTLE cluster: 1516 MHz)
- Custom thermal control driver I wrote myself (features 9 thermal throttle steps; keeps the phone cool)
- Westwood TCP congestion algorithm (enabled by default)
- No placebo patches, features, or compiler "optimizations"
- Many other misc. improvements not listed here

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, SuperSU if you want root access (ONLY v2.65 OR HIGHER), and then reboot.
If you get an error when trying to install the ROM ("You do not have the correct firmware installed!" error), then go to the Firmware link in the Downloads section and flash that zip file. Once you flash the firmware zip file, you can install the ROM.
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.

45FAQ:
1. Why did you underclock the CPU?
Answer: At the underclocked frequencies, the amount of heat generated by the CPU is quite a bit less, so the CPU is throttled less often (leading to better user experience), and battery life is better as well. The performance difference while underclocked is also not really noticeable unless you use a benchmark application. The CPU is also underclocked due to stability issues at higher frequencies affecting some OP3Ts; because of this, the CPU underclock cannot be disabled.22Underclock experiment
Since quite a few people seem to doubt the energy savings from underclocking, I decided to perform a somewhat rough test to see if it is really effective. For this test, I booted the phone into recovery (where there are no background processes running) and measured battery current statistics reported by the fuelgauge chip.
Control variables for the test:
-Enabled all CPU cores
-Disabled CPU frequency scaling (so all CPU cores run at the requested frequency without jumping up or down)
-Made the GPU run at its lowest frequency
-Disabled thermal throttling
-Reduced the screen brightness to 1/255
-Ran this command from inside TWRP's terminal: "while true; do cat /sys/class/power_supply/battery/current_now; sleep 0.5; done"
-Kept the battery close to or at 100%
-Charger was disconnected during measurement periods
I changed each CPU cluster's frequency for a few minutes at a time and observed the average battery current reported by the fuelgauge chip.
Here are the results:
Code:LITTLE big Avg battery current (positive = battery is draining) 2188800 kHz + 2342400 kHz = 656000 uA 1593600 kHz + 2342400 kHz = 651000 uA 1516800 kHz + 2342400 kHz = 649000 uA 1440000 kHz + 2342400 kHz = 647000 uA 2188800 kHz + 2246400 kHz = 633000 uA [B]2188800 kHz + 2150400 kHz = 609000 uA <-- optimal configuration[/B] 2188800 kHz + 2054400 kHz = 604000 uA 2188800 kHz + 1900800 kHz = 603000 uA
LITTLE = the frequency that the LITTLE CPU cluster was running at, and big = the frequency that the big CPU cluster was running at.
Although underclocking the LITTLE CPU cluster was not very effective, and did not provide significant power savings, underclocking the big CPU cluster was very effective in this test. Lowering the big CPU cluster's frequency down to 2150 MHz reduced the current draw from the battery by almost 50 mA, which is fairly significant.
For the next build, I'm going to remove the underclock on the LITTLE CPU cluster and increase the big CPU cluster's max frequency to 2150 MHz.
