[KERNEL] [SM-T700 WIFI & T705 LTE] [27 Nov] SkyHigh TW Kernel [R4_v2.0.0] [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-T800/805, SM-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: T700XXU1ANJ4 & T705XXU1ANJ3

Built with Stock ARM Toolchain 4.7

Compiled with KERNEL_MODE_NEON & -mfpu=neon-vfpv4 & hard float

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 !
