Korvac Kernel 2020

Korvac Kernel for Samsung Galaxy J7 F/H/M, Exynos 7580

Disclaimer

This is only J7 2015 its tested on SE 8.5 1.3 and Gaming by MdMaher. Also tested on Genesis, Firestorm OS, Lava_VX, Enigma You can report bugs here or in our telegram channel. Bugs will be fixed as soon as possible. Beta's are generally stable but if you use a beta try to report bugs to me on my telegram. This is only built for Nougat either 7.1.1 or 7.0 Touchwiz based ROMs, not for AOSP ROMs.

AS USUAL TRY AT YOUR OWN RISK AND DONT BLAME ME IF ANYTHING GOES WRONG IN YOUR DEVICE

PLEASE USE LATEST OR A NEWER VERSION OF TWRP BECAUSE OF OLDER TWRP's CANT FLASH THIS ZIP.

How to install?

1. Go to Downloads

2. Download the latest zip

3. Boot to TWRP

4. Backup your Boot

Skip to 7 if you clean flashed it with a custom ROM like SE 8.5.

5. Clear Cache

6. Clear Dalvik

7. Flash it

Versions

1. Gaming

Best for normal/heavy usage and good enough for gaming

2. Battery

Has the highest battery backup and good for light usage and battery needing people

3. Gaming 1.6oc

Has gaming features and perfect for afterburner/radon dweebs this also takes care of saving your hardware even on oc which other kernels do not.

4. Gaming 1.7oc

BUG FIXES GOING ON YET TO BE RELEASED

Same features as 1.6 but ships with 1.7oc

What to do if I have lags?

Easy answer if you have lags then its major reason is cache from old kernel try removing cache and Dalvik from twrp and also cache from the app you are having lags in. Minor lags get fixed after usage because after clearing cache app builds its own cache and thus creates lags

How does this kernel protect against oc damage?

There are multiple optimizations and multiple throttling inputs which basically keeps the device comparatively cool on oc compared to other oc kernels this also costs a little bit of performance like it might have lags on very heavy apps but this tries to save your hardware as much as it can so if you want oc and protection Kovac is the way to go. But as not kernel guarantees any protection so can't this one but rest assured if you oc the hardware life might suffer.

Note

When you clear Dalvik and cache your first boot will be slow because it rebuilds its cache and Dalvik so don't be freaked out also your battery calibration resets so you have to wait for few days so it can fix itself and show what actual battery stats are. Because users have experienced showing lesser battery stats than it actually.

What this Kernel offers?

This kernel is made to increase your hardware life and is hugely optimized for battery and lot of performance but this has no CPU overclock because overclock CPU effects hardware. Other than that it is made to avoid things like battery swelling which happens on other kernels. This isn't shipped for gaming but if you want performance or gaming you can try LKT, L speed, or 3C System Manager. And if you report bugs please make it more accurate and explain with screenshots so that I can look into it and recreate to and finally fix it.
