[KERNEL][D618 & D620][DT2W] KeyHandler Patch - LG G2 Mini

To make doubletap2wake feature work in CyanogenExtended kernels you should once downoad and flash .zip (compatible with your device & ROM of course) to add KeyHandler support in system (external module which enable screen when kernel sended a message (KEY_DOUBLE_TAP 251) to it that you make doubletap).​
For Cyanogenmod 12.x:
D618: KeyHandler already is in ROMs, you don't need to do flash anything.
D620 (also compatible with any cm12-based ROMs): https://yadi.sk/d/btiBkgZXgvLNm
For Cyanogenmod 11 (only for clear ROM, not for it's based ROMs!!!):
D618: https://yadi.sk/d/OgON5Uz2guw33
D620: https://yadi.sk/d/XF8jJB1vgvLsA
For MIUI V5:
D620: https://yadi.sk/d/yaNS_hiUgvMFs
Another CM11-based ROMs (AOKP-4.4, CRYSTAL PA) isn't supported yet - if you want to help me with it just send me your framework-res.apk from /system/framework/ and write from which ROM is it.

Maybe you mean CM12 from @invaderjohn? Don't you forget to install custom kernel?

May this even work for CM12-ROM, too?
So far I'm not able to bring that feature to life. Installed Kernel and Patch twice, did the settings - still it won't work.
Any suggestions?

Device? Did you try to disable/enable option in settings? And feature don't work when you're charging phone, don't forget.

D620 LG G2 mini.
Yep, I know.
Feature seems to work if I toggle on "Lift to Awake"- Function in Display-Settings, but with that the display wakes up every ten seconds.

This is not doubletap2wake, just "rubbish" function. Try to download kernel and keyhandler patch and install them again.

You mean like "Did you try turning it off and on again"?
Ok, I'll try...
Btw. Thanks for answering so fast!:good:
EDIT: Downloaded kernel and patch. Installed as recommended. Still no response.

Same for me here. I've downloaded nikita's kernel, and patch. Installed first kernel, then patch. Tried reactivating DoubleTap2Wake, and it wont work.đ
Also, I've typed command in TerminalEmulator that System_F mentioned with su rights, and nothing happens.

Yes, as I said, I first installed kernel, then patch... I didn't work like that, so I added command in Terminal Emulator, like system_F said, tried turning off and on DoubleTap2Wake in Display settings, but nothing happens.
OS: cm12
Phone: d620r
One thing I find strange, in settings -> About phone, phone doesen't display kernel info, but Kernel Auditor does. Screenshots provided.
EDIT: It appears I didn't have latest unofficial cm12 version. I have installed it, now works perfect.
