I will not be held responsible for anything that happens to your device after flashing this kernel. If you don't know how to bring your dead device back to life please don't make any modifications and stay with a stable rom. Also, if you think that overclocking can harm your device, overheat-it and possibly brick-it, send me a message and I'll be happy in informing you that my kernels are SAFE.​
MODEL INFORMATION & WHY OREO INSTEAD OF ANDROID 10​
This kernel was made to the 1GB Model of Redmi 2, it should work on other models too, but I will need report on that. Oreo was choosed because of the smoothness on the 1gb model I have, android 10 just dosn't work here for some reason, it's way too laggy (nick made an awesome work on it, but 1gb it's just not enought).
The rom i'm using in this device right now:
LineageOS 15.1
If you find any problems with the codec overclocking version like reboots, freezes, or any of similar problems, tell me and if you can do a kernel log.​
My name is Luan, i've started developing kernels when I was 15, at that time my kernels weren't so great, but since then I'm improving to deliver something better for the users . At the moment I'm 17 years old and I love to compile kernels and reach the limits of the device i'm using (in this case redmi 2).​
Kernel info
LH-Kernel is meant to be complex with only cool features. All of that started back in 2017 with the name HexaTurbo, as a basic improvement over the Zetsubou kernel by Ashishm94, after that I moved to redmi 4x and branded it as LH-Kernel then passed it on to Redmi 5 Plus, all of them had something in common... smoothness and overclocking! the good tipe of overclocking of course, a working one!!. Okay enough of the intro let's move on to the features!​
*linux version 3.10.108
*GPU overclock support upto 660MHz (NOTE: This overclock is a TRUE OVERCLOCK, which means that the frequency displayed is the one the GPU regulator is sending to the chip)
*Sound Control
*Screen overclocked to 75hz (only r69431 for now)
*Custom I/O schedulers
*KCAL advanced color control
*Crc check switch
*reduced load average
*UKSM and KSM enabled
*Vibration control
*Optimized
*Arch power option
*Gentle fair sleepers
*Better GPU usage and optimization
*CPU modded to go up to 1363mhz (Again, these should be TRUE OVERCLOCKS, although CPU needs testing since I don't know if msm8916 can actually be overclocked here)
*Zram LZ4
*Optimized regulators for thermal effiency
*Disabled Core Control
*Slimbus OC for better audio response
*A bunch of stuff here and there​
-Download the zip file and save it into the root directory of internal/external storage
-Reboot to recovery mode and flash the zip file
-Wipe Cache & Dalvik
-Reboot device​

Yes, it does support gestures by default

@LuanHalaiko
Can you make one for LOS 17.1
It would be more helpful to 2gb ram users running LOS 17.1

The whole point of this kernel is to make the 1gb model usable in 2020, I don't have a 2gb model to test it and I only did compile this kernel because I sold my crosshatch, until I get a new device I will be maintaining this kernel.
I could release it if there's enough demand, but for now it's just a kernel for Oreo, which I think it's the sweet spot for redmi 2 :good:

This release is for android 10, did you flash on it? if you flashed on oreo it's better to use the first build

with this build, a few minutes after booting up the screen becomes dark, only a small line appears on the top screen.

@LuanHalaiko
Tested your kernel thoroughly on android 10 everything works fine and device is more fluid than stock kernel.
The only bug is I am getting white lines on display after device goes to sleep.(on boot it is fine when I lock device it goes to sleep and I unlock then lines appear on screen.) May be problem of 75hz refresh rate. Sorry I don't know how to take logs.
And I also tested Oreo kernel,that also has the same problem.

Would you implement double tap to wake in your kernel. Even if it is for lower half of the screen would be a great boon. This has been done by a dev of mi3w cancro for los17.1 build.

Can you report the screen model of your redmi 2? it will show in the first page of Device info HW app

Report your screen model so I can ajust the overclock for it, you can check in any rom by downloading the Device info HW app from playstore

Gestures are already supported, you need to enable them in a kernel manager
