[KERNEL] [SM-N915 S-K-L Exynos 5433] [21 Apr] SkyHigh TW 5.0.1 Kernel [v1.1] [Synapse ++]

PLEASE POST QUESTIONS THAT ARE NOT DEVELOPMENT RELATED IN Q&A HERE. THIS WILL HELP KEEP THINGS TIDY
BEFORE POSTING, ENSURE YOU READ POSTS #1-3 AND SEARCH THREAD FOR INFO FIRST. THANK YOU FOR YOUR ASSISTANCE


AS I HAVE NOTICED A CONTINUAL PROCESSION OF USER KANG MY WORK, SO I HAVE DECIDED TO RELEASE MY LOLLIPOP KERNEL. BE WARNED, THOSE WHO KANGWITHOUT PERMISSION WILL BE REPORTED !! I WILL LISTEN IF ASKED, BUT NO GUARANTEES !!


** I WILL NOT BUILD FOR ANY DEVICES THAT I CAN NOT PERSONALLY TEST & DEBUG. DON'T ASK, BECAUSE YOU WILL BE IGNORED !! I DON'T USE A SNAPDRAGON DEVICE .... **.


Let get it straight, I am not a real Developer, but I am UpInTheAir, former part time kernel “hack” of SM-T700/705/T800/805, SM-N9005 LTE, SGT 7.7 JB & ICS Kernels. I now share with you my Exynos 5433 TW SM-N915 S-K-L kernel compiled & modified 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 GOOGLE Just like I do …......

• ramdisk source: N915SKSU1BOC1


• Built with stock ARM Toolchain GCC 4.7


• Patched to Linux 3.10.19


• ARM: full neon-vfpv4 support & compile with -mfpu=neon-vfpv4 + optimizations


• KNOX WARRANTY VOID: 1


• SELinux PERMISSIVE (for Titanium Backup and other apps to work correctly)


• TIMA disabled


• adb insecure


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


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


• Possible Screen Mirroring / AllShare Cast fix


• Secure storage = false (should prevent WIFI settings & passwords wiping on flash)


• Synapse app support for many kernel configurations + more !!


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