Hi! Tell me plz, is any way to install OOS blobs or special\custom kernel (to fully work gcam) on LOS16 ?
Hi Denser thanks for updating the ROM.
You need to update the build.prop so apps can update, are you able to change it to Google Pixals?
I am not able to run Android auto using this rom. Can it be fixed @[denser] ? My other phone on the same head unit works fine. Using this rom when i connect its shows usb not supported. I am pretty sure the issue is something with the rom.
If I open my OnePlus One’s build.prop in a text viewer I see the following 2 lines:
Is it that getprop doesn’t display values from the system/build.prop file? Would it be safe to use setprop in TWRP’s terminal to change those values, or should I edit build.prop in a text editor instead? Should I still try to change ro.build.description & ro.build.fingerprint given what getprop returned (I’m experiencing the issue of some apps not updating via Play Store)?
I’m wondering if denser’s latest build(s) already changed the fingerprint, because I still have the issue of some apps not updating.
However if I use getprop from the terminal in TWRP 3.2.3-0 to pull these values (I was actually experimenting to see how I could edit build.prop within TWRP rather than adb) instead I get:
Can anyone explain this apparent disparity for me? I’m running denser’s latest build (2020.01.09) unrooted, I mounted the system partition in TWRP but only read-only so far.

This is an unofficial LineageOS 14.1 ROM for the OnePlus One that focuses on stability and the overall 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 unless otherwise noted. I will NOT provide support if you install a custom kernel.
ROM features:
- Based off latest LineageOS 14.1 sources (root access is NOT included)
- OTA updates via built-in updater in Settings
- Nougat Stagefright camera hardening (improves security; more info)
- OxygenOS camera libraries (no significant camera bugs and improved camera performance)
- Custom camera app that comes with many unique features (such as high-speed video recording with audio)
- Custom camera HAL featuring:
-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 included camera app in order to use high-speed recording)
-1080p video recording with the front-facing camera
-1440p video recording with the front-facing camera and back camera (only with the included camera app)
-4k video recording at UHD and DCI resolutions
-Manual focus control
-Manual ISO control
-Manual shutter speed control (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_rb1.15)
- 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 (makes the phone feel smooth without destroying battery life)
- CPU underclocked to 1958 MHz by default (you can disable this; see why this was done 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 (features 8 thermal throttle steps; keeps the phone cool)
- LCD KCAL by Savoca
- Westwood TCP congestion algorithm (enabled by default)
- 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 ("bacon.verify_trustzone" error), then first you must install/use the latest TWRP recovery (3.1.1-0). 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 this ROM. After flashing this ROM, flash a Google Apps package, and then reboot.
Installation instructions (for updating to a newer release):
If you are already running this 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.
Downloads:
ROM:
Google Apps (required): Platform: "ARM", Android: "7.1", Variant: "micro" or "nano" (I will not provide support if you install a different variant)

Last Updated 2020-01-09122FAQ:
1. 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 can modify the proprietary camera libraries, so there is no way for me, a regular consumer, to implement exposure times greater than 2 seconds.
2. 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
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.
3. Why did you underclock the CPU to 1958MHz?
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.90
I'm surprised Sultanxda still manages to balance loads of college homework with a part time job while maintaining this ROM.47
