Advance Stock Kernel or Custom Kernel?

Is there any Kernel available for our device? That is compatible with 4.43 and 5.1.1 Stock or custom roms? Can someone make it? Hehe. Thanks.
Has features like:
- A very fast kernel that improves Ui smoothness and performance without overclocking Cpu and Gpu. Like other phones that has similar specs.
- CPU Overclock to 1.6 GHz.
- Adreno 305 Overclock to 500 MHz or higher that won't affect phones lifespan. (Galaxy Mega 6.3 has Gpu clock at 500 MHz so it's possible for our device.)
- An equal or better Battery Life.

How to turn off touch key lights in Samsung S advance i9070 F-aosp Custom rom

Hello All,
This is my first post so if there is any mistakes pls let me know.:o
Sorry for my bad English :p

Anyway It is as the tittle says- How to turn off soft key/touch key lights on the custom rom F-aosp for Samsung Galaxy S advance i9070
I know that I should asked under the corresponding thread but due to Insufficient posts I couldn't. So if anyone know any way to turn off the touvh key lights pls let me know. I tried searching the settings for this but I couldn't find it. I want to do this because one of the touch key(which is the "back" key) does not light up because my touch panel is slightly broken. Everything else is fine with me.
So if anybody can, Pls Help Me :)
Thanks in Advance :D

No wifi after skydragon flash, sorry in advance

I know there are multiple places to get answers for this but i got really confused after reading some of them about falshing the firmware. I really need an idiot guide to get this done right and so i don't brink the phone.

Little background on it. It is an AT&T phone currently on cricket network (at&t owned). I was waiting for the Lollipop update to come through and i got nothing and little help from either cricket or AT&T after it was released i might also add. So eventually i got aggravated enough to do something else. First i unlocked the bootloader through HTC hoping i could get some kind of update. No luck. Then another month went by and the aggravation set in again, i finished up the job and rooted the device. Another day and lets install a custom ROM. Went with skydragon. Had some issues, did some more reading and "sunshined" the phone to get s off. So last night i got skydragon to install properly and was loving it for about 2 1/2 minuted guess what no WIFI. So all the stuff i already did i viewed as being easy, bootloader unlock, TWRP, backups, rooted, s-off ; but now i am a little confused about how i should proceed as i want to put skydragon back on with wifi. Can someone please simplify it for me. Here is all the relevant info (i think)
