[KERNEL] [SM-T700 WIFI & T705 LTE] [28 Feb] SkyHigh TW Kernel [R4_v2.8.0] [Synapse ++]

8.4" SM-T700 WIFI & T705 LTE TW Exynos 5420 supported in thread only !!

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 SM-N915S/T800/T805/N9005 LTE, SGT 7.7 JB & ICS Kernels. I now share with you my Exynos5 TW SM-T700 WIFI & SM-T705 LTE kernels 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 !


FEATURES

* Based on official Samsung source: T705WVLU1ANJ5

* ramdisk source: T700XXU1ANL2 & T705XXU1AOA1

* Built with Stock ARM Toolchain 4.7

* Compiled with KERNEL_MODE_NEON & -mfpu=neon-vfpv4 + optimizations

* ARM: UNALIGNED_ACCESS

* KNOX WARRANTY VOID: 1

* SELinux PERMISSIVE

* adb insecure

* ROM Knox disable/freeze via Synapse control

* init.d script support (drop in script & set permissions to 755 or 777 and reboot)

* busybox v1.22.0-Dream-IRC installed to /sbin

* Will NOT delete your WIFI settings & passwords

* Possible Screen Mirroring / AllShare Cast fix

* Synapse app support for almost all kernel configurations + more !!

Many descriptions are in the app ! If you require more info, don't be lazy, please SEARCH like I did !
