F.A.Q :

Q - Why you mustn't quote the hole post ?
A - As you are killing us dude !

Q - Why mustn't I ask for ETA ?
A - Simply , we are students and colleges so we are busy with our studying and other life problems !

Q - Why mustn't you Spam ?
A -As Organization Is the key to achieve the impossible !

Q - Why must you delete "audio.primary.sc8810.so" in "/system/lib/hw" ?
A - As it make "mediaserver" crashes and prevent the ROM form booting !

Q - Why should I flash custom luncher ?
A - As cm12,1 default luncher crashes so you won't be able to go father than home screen !


Q - I have faced some issues, which is not mentioned in the 'Not Working' list........?
A - For bug reports, the least we can expect from you is a logcat taken during the issue. Or atleast, you could tell us how and when did you face the bug, how can we reproduce the bug to fix it. Reports without any of these will be ignored.

Q - Can I use your ROM/any part of ROM and modify it and release it separately?
A - Yes you can. But please mention proper credits.


Q - I flashed this ROM, but I dont find any Google App, where can I find it?
A - gapps will be mentioned later in OP but you can get them from any where and flash it !

Bug reporting
How to report a bug?

• First off all, check the 'not working' list and see if the bug you are facing is already mentioned or not. If it is, stop right away because the concerned people working on the ROM are aware of the issue.
• If the bug/issue is not mentioned in 'not working' list, check the Frequently Asked Question (F.A.Q) and see if issue is resolved already.
• If the issue you face is not in FAQ either, you would probably post a reply in this forum, and not PM anyone, about the bug.
  • Attach a logcat.
  • If not possible, mention a proper way how you encountered the bug.
  • Also mention any 3rd party stuff you installed. (Like mods, themes, kernels etc)

Following things WILL NOT be considered as bugs. So please do not post such bug reports, they will be ignored.

• Low benchmark scores. Even if Stock results better.
• Poor performance in gaming. Even if Stock results better.
• High RAM usage/low RAM available.
• Various kernel control app crashes.
• Crashes of various UI elements when a custom theme/mod is applied.
• Random reboots, and other issues caused by flashing custom kernel.

[psych.half]

Now who's gonna test my kernel for CM11. Man I'm always late to the parties...

Well, time to work on CM12 kernel then...
@corphish cpufreq driver's. up.. https://github.com/mint2g/kernel_module_cpufreq-driver

And guys frequency scaling will be available as an additional zip.. i saw some of you taking about frequency and if you just keep it set to higher frequency like in previously broken driver.
Youre gonna damage your device. Cause this one really works

 

[bvrraju]

Thanks @LahKeda Sir and all devs
Finally we have cm based lollipop ROM . waiting for fixing bugs and stable realese .
Thanks again
I have a thought about installing launcher without computer.

Place any launcher apk (which u want) in ext SD card before flashing cm12.1
After flashing cm 12 , kernel nd deleted audio primary. So
again
Mount system and extsd and
Using aroma file manager place launcher apk to system/app/here.
Done.
Hit thanks if I helped

@psych.half

So I cloned the cpufreq-sc8810 module source and built it.

And then pushed it to system/lib/modules
And then when I try to insmod it, I get this error :

insmod: init_module failed (Exec format error)

Also, the .ko generated here is 5kB, the one in the zip you uploaded is 10kB.
The kernel I used was yours. Can it be due to signature verification?

Should I try the unstripped module?
