CyanogenMod is a free, community built, aftermarket firmware distribution of Android 5.0.x (Lollipop), which is designed to increase performance and reliability over stock Android for your device.

Code:

CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for CyanogenMod is available in the CyanogenMod Github repo. And if you would like to contribute to CyanogenMod, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.

Known Issues (regarding latest available Stable build)
Please do not report bugs if it is already listen in the list of known issues

Rarely, when you wake-up the device, touchscreen will have a noticeable input lag, easily fixable by turning off and on the display. (H/W or S/W bug?)
Wireless Display with some TVs could cause issues (AOSP bug related to HDCP, and Google doesn't provide a solution)
Video Stream through Screencast & Wireless Display will have inverted Red and Blue color channels due to BGR Pixel Format (actual Exynos sources don't allow to fix it)
Any Chinese (CHN, I9500XCUxxx codename) Baseband/Modem reduces Call Quality (due to forced AMR_WB, unsupported by CHN modems)
5GHz Wi-Fi Networks using Band B (52-140) and Band C (149-161) channels won't be listed (H/W or S/W bug?)

Reporting Bugs

You are allowed to report bugs only in this thread. Before reporting a bug, please make sure you are running as stock as possible. This means no custom kernel, no custom framework modification, etc. If you are using any of the above modifications, please flash the rom again to get rid of the modifications before reporting.

REPORT BUGS IN THIS THREAD ONLY

Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
If it is a random reboot, grab /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log

Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. The following is a useful format to follow. Note: If you can provide the latest night/build that the bug didn't exist, it would greatly help in tracking down what caused it.

Code:

What is your--
Phone model:
Radio (baseband) version:
GearCM version:
GearCM download url:
Google Apps version:

Did you--
wipe data/factory reset:
restore with titanium backup:
reboot after having the issue:

Read carefully.

Differences between GearCM (Optimized CyanogenMod) and Official CyanogenMod (NIGHTLY):

Degrated Shadow said:
Enough of those dumb questions..
The official CM rom is maintained by @Alberto96 and @intervigil
He makes the very recent changes here relating to performance.. which are then in time pushed to CM official rom. The kernel is different because it has selinux disabled and few minor tweaks you might not even notice.. this gearcm rom will have more performance. But CM rom will have their updated base changes which are included here with each update.
What I mean is you probably wont even notice what's different in terms of user interface.. gearcm will have more performance. Official cm will have updated sources. But it will include gearcm's changes in time as @Alberto96 pushes them to CM
You can decide by a simple choice. more performance and not-nightly updated sources or similar performance (improving with nightly updates) with updated sources. I would choose gearcm because of the reasons I mentioned above. Do what you will.. and let this be a note to everybody who ask this again and again and again. Don't spam the thread with same question in every alternate page.. Because there are other people who might have different problems they need to ask. Read atleast 15 previous pages and the first post changelog before asking the question. Reading most of the times will give you a solution and if not most of the info you will read will help you anyway.

FAQ (Frequently asked questions)

Where are "Performance" and "Developer Options" categories?
To activate 'Performance' and 'Developer Options' categories in Settings you need to tap 7 times on 'Build number' located into Settings -> About Phone.

How can i solve problems with Hebrew language?
Go to "Developer Options" in Settings and check "Force RTL layout direction".

What can i do to reduce the "echo effect" while in-call?
Try to reduce in-call earpiece volume (if possible).

I'm having problems with battery life, what can i do?

1) Use "Greenify" to hibernate all apps with a "little cloud + 'Gcm' word inside" on the right of each app's name. Donation version is recommended because it allows deeper hibernation of apps

2) Disable "Location" or set it to mode "Battery Saving" (Settings -> Location)

3) Make sure that your 2G/3G mobile network signal level isn't always low or unstable

4) Deny "Wake Up" and "Keep Awake" permissions to Google and third-party apps. (Settings -> Privacy -> Privacy Guard -> Press menu button and check "Show built-in apps" -> Press menu button again and go to Advanced -> Horizontal Scroll to Device)

5) Disable "Sync" or sync only useful stuff like Contacts

6) Disable "Auto-rotate screen" (Settings -> Display & lights -> Rotation)

7) Use one of the latest Modem/Baseband listed on first post.

8) Disable Ambient Display

9) Install Xposed Framework and configure Amplify

If this isn't enough then replace your battery and/or reduce your phone usage. :silly:

Is GearCM OTA supported?
Yes

(Since 20150707 Build)

Why is my phone over-heating while playing heavy-games or running heavy-apps?
Use a bit your brain to explain why. High CPU and GPU usage = high heat production. Your phone will automatically throttle CPU when needed so don't worry, it is safe and normal.

Can I use another kernel instead of the one included in the zip?
No. Only use the included kernel for 100% compatibility, bug reports with non-standard kernel will be ignored.

Can i disable S-View cover features (lock/unlock)?
Not yet.

*** IR Remote app isn't working anymore/was working on previous builds/causes my phone to crash, what can i do?
Contact *** IR Remote app developer.

Any question about "Can't connect to camera" issue
Do not "stress" camera on CM because we don't use yet a proper implementation. Open/Close Camera apps carefully without force-closing them.

fix stock camera try flash this zip https://www.dropbox.com/s/z2a7hegwzu9ft2c/Fix_Camera_Cmmct_5.0.zip?dl=0

RoCorral · Dec 16, 2014 at 9:38 PM

Been using lollipop as a daily driver with awesome results. But still there's something that bugs me. Although GPS works fine I find that its accuracy is pretty low.
For instance I run in order to keep fit. I use adidas miCoach which calculates your speed and distance covered giving as result km speed (from Argentina). GPS has a hard time keeping up with this and every time I train I revert to TW and then back to Lollipop.
Will test this GPS and see if its better than team Cajinica

AndresSanzH · Dec 16, 2014 at 11:08 PM

does this rom have working bluetooth calls over car stereo?

"App not installed" if manually install an apk.
Is there any workaround?

RoCorral · Dec 17, 2014 at 8:57 AM

@Alberto96 haven't test it on GearCM 11. I'll try and report back asap

rohanchrome · Dec 17, 2014

Can't install apks.
Although pushing apks to system works. Titanium backup in not able to restore as well.

Edit: I guess Titanium Backup does work. Not with the default superuser though. I flashed supersu to get it working in frapeti's rom, strange.

With GearCM 11 latest build GPS is pretty accurate. Used Waze while driving and miCoach while walking and had good results.

Further testing done with the build posted (20141216) I can't access SD card to install apks that are not from playstore for example BBS, and getting the low memory message even if full wiped and fresh installed.

jamboz · May 7, 2009 37 4 0

Can't install APK in this Build ...

BlaqueDroid · Dec 18, 2014 at 4:11 PM

Storage Issues

@Alberto96 Hey man there seems to be an issue with your Kernel please take a look at the changes u made as they seem to be the cause of peope not being able to install any APKS and Install from playstore as its complaining about the storage being low so what i did is compile with CM kernel and tested it and the GearCm works fine without any storage issues but if I compile it using ur GearCm Kernel thats where theres storage issues. Please take a look at it

ElectroNinio · Dec 19, 2014

Thanks for your time and dedication of this Alberto. Unfortunately I'm having a hard time with your CM12 Releases

With CM12-20141212v2 (I did a clear wipe) and no RIL Service. So I was not able to use it basically...
Today I gave it a second try CM12-20141216 . I was happy to see my 3G Connection. But when I started to download the app from Play Store. It was impossible. All APKS giving an error.

I will test Canjica Version. It's a pity but I will have to wait till we get to a stable version of Android 5.0.1 with GearCM12.

Despite of that, Thanks for your work on this! We wouldn't have this if it wasn't because of you

prabhjeet.oberoi · Dec 19, 2014 at 7:40 AM

Heads Up

Brilliant to have 5.0 on our phones, look and feel is really cool.

Confirmed Working:
Calls, SMS, Internet (WIFI & 3G), Camera, Gallery

FC's:
Music, File manager, Play store (all google apps) & anything else which is on the SD card

Keep it up guys:good:

Slaytter · Dec 4, 2012 22 9 0
