[KERNEL] [SM-T700 WIFI & T705 LTE] [12 Mar] SkyHigh TW KK Kernel [v3.3 FINAL] [Synapse ++]

8.4" SM-T700 WIFI & T705 LTE TW 4.4.2 Exynos 5420 supported in thread only !!

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 :)

THREAD RULES & PROTOCOLS FOR THIS

DEVELOPMENT

THREAD:

BY POSTING

YOUR ISSUES

IN THIS THREAD, YOU ARE AGREE TO ABIDE BY THE FOLLOWING

DEVICE MODEL

ROM and firmware version etc

EXACT steps taken to reproduce YOUR isssue

Screenshots (if applicable)

Did you read Posts #1-3 completely?

Did you search the thread, XDA or GOOGLE?

Did you follow the install instructions EXACTLY?

What was your previous kernel?

Do you have any other known kernel tweaking apps, scripts or mods? (remove them)

Try older kernel (don't not flash anything older than v0.9 )

Try lastest stock firmware (without custom ROM - if you have installed)

ONLY IF YOU HAVE TRIED SUGGESTIONS ABOVE:

Turn on logging in Synapse and save logs AT TIME OF ERROR. AND post together with ALL the above information.

ELSE, DON'T WASTE MY TIME, YOU WILL BE IGNORED AND/OR POST REPORTED !!

THANK YOU :good:

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 !

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 !
