How to change android physical buttons (On Galaxy, LG, HTC ...) get system write access

Hello and welcome to this new Android tutorial, today I'll guide you on how to change the physical touch buttons on your android device such as Samsung Galaxy S4 or S5, HTC One, LG G3/G4 and more, you probably install or change your ROM to a new one that has different buttons layout or you need to change it for other reason, this tutorial will guide you.

In my case I want to change my Galaxy S4 buttons layout to the default S4 standard layout with menu button and long press home for recent app.

So to change the keys, you need some tools:

  • First thing first your android must be rooted, if not search google or our blog for the root process.
  • Now Install an app named "Total Commander" from Play store.
  • Using Total Commander navigate to this path "system/usr/keylayout/"
  • Now edit the Generic.kl file using the Total Commander editor.
  • Backup the Generic.kl for security propose !
  • Here on this file you can see all keys layout for your smartphone for Samsung galaxy to change menu button back to standard search for key 254 and change APP_SWITCH to MENU, the key 217 is for gome long press, you can change it to SEARCH.
  • Now press save and the Total Commander will ask to unmount system to make it read/write, confirm that.
  • Now reboot your smartphone to check changes.
That's it now buttons must be changed to your desired layout.

Core i7 6700k Vs i7-5820K Vs i7-4790K first benchmark leaks and specifications comparison

Today I want to share with you some new leaks about the all new next generation Intel's desktop processor, the 6th generation of core series code named Skylake-S built using 14nm process technology, a "tock" step in the "tick-tock" intel"s release cycle strategy the Skylake-S will support LGA 1151 socket and DDR4 controller.

The new 6th generation will require intel's Sunrise Point based X170 mobo, also to support DirectX 12 coming with Windows 10 later this year, a PCI Express V4.0 is supported and a 512 bit FPU width will make this chip special, with only 14nm process size users can push the Skylake-S to an unknown limits.

Some primary specifications about the series:

Benchmark results:

PC Mark 8 benchmark Score:

According to the leaked benchmark from, the difference is 15% compared to the previous generation when considering the clock speed difference, so if you are a good overclocker with a good cooling system you can push it and get an outstanding result !

DirectX 12 Vs DirectX 11 a real Multi-Threaded API !

Just few months and Windows 10 along with new DirectX 12 will be available for public propose, AMD is excited to announce some of the DirectX 12 features with an interesting improvements over precedent versions.

The new DirectX 12 will be up to 45% faster than DirectX 11 according to previous news, with Async-Shaders technology and Multi-Threaded Command Buffer Recording allowing smoother real time gaming performance with the uses of all CPU cores simultaneous, AMD report about Async-Shaders technology that it “allow usage of a game engine to execute GPU compute or memory activities during “gaps” in the graphics workload presented by a game.” the past versions just allow one line for executing between GPU and CPU to execute graphics rendering operations:

“In DirectX 12 Async Shaders supercharge work completion in a compatible AMD Radeon GPU by interleaving these tasks across multiple threads to shorten overall render time. Async Shaders are materially important to a PC gamer’s experience because shorter rendering times reduce graphics pipeline latency, and lower latency equals greater performance. “Performance” can mean higher framerates in gameplay and better responsiveness in VR environments. Further, finer levels of granularity in breaking up the workload can yield even greater reductions in work time.”

DX12 Multi-Threaded Command Buffer Recording features:
  • Overhead is significantly reduced by moving driver and API code to any available CPU thread
  • The absolute time required to complete complex CPU tasks is notably reduced
  • Game workloads can be meaningfully distributed across >4 CPU cores
  • New “bandwidth” on the CPU allows for higher peak draw calls, enabling more detailed and immersive game worlds
  • All available CPU cores may now “talk” to the graphics card simultaneously
