[Galaxy Tab S Original Android Development] UpInTheAir:
[KERNEL] [CM PORT] [07 Oct] SkyHigh Kernel [R3_v1.4] [Synapse ++]

I only have so much free time, so I don't plan to update this kernel. I have other devices I tinker with and personally use.

I have given Devs who have publicly released their CM ROM's (as per GPL and XDA rules) and kernel sources on git, to use what I have done and adapt it to there needs.

This kernel is currently compatible and built for use with the CM ROM Port by @eousphoros. As I don't own or use a T700 WIFI device, I can't guarantee if this kernel will fix any issues or create more. Up to YOU to find out ;)

I don't have time to build for any more devices I can't personally test & debug - sorry.

Let get it straight, I am not a real Developer, but I am UpInTheAir, former part time kernel “hack” of TW SM-T700/705/800/805, SM-N9005 LTE, SGT 7.7 JB & ICS Kernels. I now share with you my Exynos5 CM Port SM-T700 WIFI kernel compiled from official Samsung sources.

* I don't pretend to know everything, so if you can be constructive and help out this project, please do so. You will find allot of answers by searching gitHub, XDA and SEARCH ;) Just like I do …......

>> SCREENSHOTS << from v0.5 : might not be always up-to-date !
