Thank you for your work, may I request you to please cherry pick "prevent accidental wakeup" from Cm13?
its very annoying, screen is waking up and doing random things when in pocket.
Hi folks
Just thought I'd let anyone having doubts or worries about moving to the new version (13 - 6.0.1), I upgraded about a week ago and all is well, apart from a few little app crashes here and there (nothing major).

based on my experience, it's better to wait till autumn before upgrading to major version
@takkischitt
I am talking about my experience
stable enough version appears somewere in a year after first night build
before that it's all about minor/major bugs and fixes
android itself also is not a bugfree system right after release

@Sultanxda Your cm 12.1 roms are amazing!!! After flashing this rom i have never shifted to any other rom (even if i did i come back).
There is a problem that I am facing. It is not cancelling the background noise when I talk to other people i.e. there is too much distortion and the other person cant hear my voice and can here the distortion very loudly. The noise cancelling is not working (The microphone seems to be the problem). I also tried re-formatting it several times. Please help me with the solution as I cant stand any other rom! Thank you.

They don't usually, but it would depend where you're downloading from. It is maybe a temporary issue with the server, or your internet connection.
Useless build...
This build probably does not make sense to be honest as Sultans CM13.0 builds is perfect in my opinion.
But as I was bored I spent a few hours to see if it was possible to cherry-pick + adapt his kernel and device changes from CM13.0 to CM12.1 so here is a "stable/cm-12.1-YOG7D" build with "September 1, 2016" Android security patch level.
It's a "userdebug" build so it has built-in root (which is different from the official Sultan builds). Upgrading from Sultans latest build should be possible but I did not test it.
The official Sultan patches https://github.com/CyanogenMod/andr...mmit/e75f59e7fd349dd1fa5d452086c795f693776d89 and https://github.com/sultanxda/android_frameworks_base/commit/0cbd4a88767d78640b7dd391674575f7d5e517e6 are not applied (as I personally don't see any advantages for applying them) therefore the "Lite" in the name.
I've flashed the 20160918 build and used it for a day without any issues but have returned to Sultan CM13.0 as I really see no reason to stay on CM12.1
cm-12.1-20160918-SNAPSHOT-YOG7D+SultanLite-bacon.zip
New build (This is untested so please take a backup before flashing and report back if it works or not).
This contains Sultans latest 35 kernel commits so it should be as very similar to "cm-13.0-ZNH2K-20160921-STABLE-Sultan-bacon.zip" with regards to kernel and device tree.

Ah... If I'd only could build it for kenzo+radon kernel....
Great idea! I still have my OPO but my daily driver is a Xiaomi Redmi Note 3 Pro (SD650).
There's a a feature missing in cm13 code, which is the ability to toggle a SIM card off.
CM12.1 has such feature, which I miss a lot. So, I'll consider making a test build using your instructions but for kenzo for private use.
Thank you for your effort. And no, a updated cm12.1 build with latest security updates would be great.

This is an unofficial CyanogenMod 12.1 build I developed after seeing some of the craziness in the official CyanogenMod kernel (such as massive merges from different sources and untested cherry-picks that introduce random reboots), as well as craziness with CyanogenMod's camera libraries. If you just want your phone to work without any fancy frills then you might be interested in using this. The ROM is the same as official CM12.1 on the outside, but there have been many optimizations under the hood. It comes with a fancy unique kernel I worked on that is cleanly based off of the latest CAF sources from Qualcomm.
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 12.1 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 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 Lollipop kernel source from Qualcomm (LA.BF.1.1.1_rb1.26)
- 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 might work better)
- Newest available Synaptics touchscreen firmware (no battery drain)
- Dynamic CPU input boost driver I wrote myself (makes the phone feel smooth)
- 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 driver I wrote myself (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"
- 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, and then reboot.
If you get an error when trying to install ("oppo.verify_trustzone" error), then first you must install/use TWRP recovery 2.8.6.0 (TWRP 2.8.7.0 cannot properly update the modem). Next, download and flash the latest official CM12.1 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, and then reboot.
Installation instructions (for updating to a newer release):
If you are already running my CM12.1 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.

183FAQ:
1. What is the difference between the stable and nightly builds?
Answer: My ROM builds are based off of the stable CM12.1 code branches, whereas the official CM12.1 nightly builds are based off of the nightly CM12.1 code branch. Stable builds provide much better stability than nightly builds, but they don't receive updates as often as the nightly builds. Stable builds are separate from the nightly builds; you cannot install a stable build on top of a nightly build. The stable builds are the same as the SNAPSHOT builds on CM's website.
2. Could you add camera slow-shutter times greater than 2 seconds?
Answer: No, I cannot. The reason why exposure times are capped at 2 seconds is due to the proprietary camera libraries from OxygenOS. Only OnePlus and Cyanogen Inc. can modify the proprietary camera libraries, so there is no way for me, a regular consumer, to implement exposure times greater than 2 seconds.
3. Why did you use OxygenOS camera libraries? They don't have 4K camcorder support!
Answer: My custom camera HAL enables 4K camcorder support with Oxygen's camera libraries, so this isn't an issue. Cyanogen's camera libraries have had some issues with the camcorder since day 1. The big issue that I have been able to reproduce on all OnePlus One devices I've come across is graphical artifacts in recorded videos (look towards the right @25 seconds): https://youtu.be/LyIbb5wIyfY?t=22s
(issue report on JIRA: https://jira.cyanogenmod.org/browse/BACON-3582)
OxygenOS' camera libraries do not have this issue, and thanks to my modifications, we now have 4K camcorder support with the OxygenOS libraries, so not much is lost by using them. The OxygenOS libraries can also take pictures faster/better than Cyanogen's libraries.
4. Why did you underclock the CPU to 1958MHz? Yer crazy, bro.
Answer: At 1958MHz, the amount of heat generated by the CPU is quite a bit less than at 2457MHz, so the CPU is throttled less often (leading to better user experience), and battery life is better as well. The performance difference between 1958MHz and 2457MHz is also not really noticeable unless you use a benchmark application. If you want to remove the CPU underclock then flash the zip from the first post that disables the underclock. You must flash this zip every time you install a new ROM update.71
I hate Nexus devices, and I just spent 4 months reprogramming my OPO to make it work, so why would I ditch it and waste all the time I spent working on the OPO?
My OPO works fine, and as long as it works I won't get a new phone for maybe another 1.5 years. No reason to burn money and time for a new device.70New stable build uploaded. This build is different from the builds I've provided thus far. The build is based off of the stable/cm-12.1-YOG4P branch of CM12.1, and it is basically my equivalent of COS12.1 (it is not actually COS12.1). It's a bummer, but you must perform a clean install to switch to the stable builds. I'll try and maintain the stable builds separately from the regular nightly builds I've been providing so far, so the stable builds will receive separate OTA updates from me and such. Updates will be released much less frequently for the stable version, as it's meant to be just that: a stable version. If you're the kind of person who would use COS12.1 then you may be interested in switching to the stable version. Personally, the soft reboots were killing me, so I'm currently using the stable version.
There is more detailed information on the stable version in the FAQ, and there are updated installation instructions in the OP as well.
Let's see how this goes :silly:
