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 bugs

• IR Blaster doesn't work.

* If you want to report any other bug, please explain how to reproduce it and attach a logcat and dmesg (you can use this app). Please, do not report bugs if you use a kernel from a different thread.

Bootloader

This rom is meant to be used with kitkat bootloader. If you are unsure of what bootloader you are using, you should flash the following zip within recovery (official TWRP recommended):

V50020D Bootloader: https://www.androidfilehost.com/?fid=23991606952613675


* Some stock based roms in this forum flash bootloader files without the user being aware of it. So just to be safe, I recommend everybody to flash the above zip to make sure that you are using all the correct bootloader files.

Thanks for creating this! Finally there is a CM12.1 solution for v500 devices that use the other camera module. I am able to dirty flash this ROM on top of the latest official nightly cm12.1 build without any problems.

Thanks for this one, sounds awesome, flash time

Hey. Thanks for your amazing work. Would it be possible extract this kernel for work in aosp roms?

Of course, you can extract it or even better, build from source. But it's possible that you need some extra changes in the device repo.

 

[cianz94]

Thanks for your reply. I'm not an expert to extract kernel. Can you extract this please? If you can. Tanks a lot.

If you think that will fix camera for all available roms, that's not how it works. Kernel aside, you need new blobs (vendor files) and changes in the device repo (sepolicy rules, ramdisk, ...) to fix camera. I publish all my repos so everybody can see them, and other devs can either use them to build their roms or try to "extract" the changes for camera to fix it in their builds. But I cannot do much more than I already did publishing my sources and this rom...

 

[fefifofum]

New build released

With the following changes:

- Set lcd brightness to default value during first boot.
- Kernel updated to latest caf tag for our soc.
- Fix vidc firmware error.

I will keep publishing new builds of this rom whenever there are significant changes in CyanogenMod's or my repos.

really awesome build, i can even push apps to sd, for some reason this never worked for me on default cm
it even feels smoother

Thanks, I will need to make some changes to the repos to make them to his liking.

Auto-rotation isn't working (Clean installation of the 10.6. build). And yes, I did a reboot.

works fine for me, but I'm pretty sure i've read something similar yesterday on the official cm12.1 thread,
the "solution" seemed to flash the rom another time.

 

[bjcrj]

Thank you for this ROM! Smooth and stable! Still getting the external sdcard bad removals when device sleeps, but thats the only issue i have found. Thanks!

 

[ol31]

This is just a perfect build!
No issues. Even my BT/Wi-Fi disconnect issues are addressed.
Thanks a lot!!!!

 

[dadaa1]

no rotate for me also, and no help for installing two times

Auto-rotation isn't working (Clean installation of the 10.6. build). And yes, I did a reboot.

I had the same problem - multiple rebooting and re-flashing the rom didn't help. I finally fixed it by flashing the latest official nightly CM12.1 rom (which immediately fixed the rotation problem), and then flash back this rom.

BTW I came straight from stock 4.4.2. Never flashed anything before. Not sure if this had to do with the rotation problem.

New build released

...with working HDMI and improved gamma. I think I also solved the issue some users are having with auto-rotation, but since I cannot reproduce the bug I cannot confirm whether it's fixed or not.
