[Galaxy A3, A5, A7, A8, A9 General] XperiaNoobie:
Addition 2.0 Rooted users ONLY

Hello guys , after some time and some digging through I managed to find some cool additions regarding the last post :D In this guide I will be focusing on additions that

ONLY Rooted

will be able to pull off . Although the steps are not really hard ,

I suggest you proceed with your own risk, I am not responsible if anything happens to your device. (Although I will gladly help you if you need anything).

In order to proceed you have to check if you are Rooted , else this will not work.

So we will be doing the following things to our devices. [I have tested them on my Galaxy A700F running Lollipop (on TrapKernel) , But you should be fine no matter what phone from the A-Series (A3, A5, A7 and all of the other variants) you have.]

1)Adding a working Navigation Bar

2)Disabling the softkeys (Back and App Swapping Button)(and the backlights)

What will we need for this:

1)An A-series Rooted phone (duh!)

2)A Build.prop editor (For this I will be using a multiapp called "Device Control", But any build.prop editor should work)

3)Patience

4)And to follow my steps

Before we proceed I warn you that there are some bugs like the nav bar being consistent while youtube playback and while shutting of the device but I am looking for away to resolve them , so stay tuned !

Now let's begin :D

i) First of all download from the Playstore the Device Control app.

https://play.google.com/store/apps/details?id=org.namelessrom.devicecontrol&hl=en

ii) Open it,and grant SuperUser access

iii)Hit the 3 vertical lines on the upper left corner, scroll down and tap on the "More..." tab

iv)Open up the Build.Prop option

v)Now hit the "+" on the upper right corner and type the following

Name

qemu.hw.mainkeys

Value

0

It should look like this:

vi) Hit save and then restart your device. When it's all booted up you should notice that the new Nav Bar is there and is usable.

But the Appswitch and Back buttons are still working so we should get rid of them.

i) Go to the Playstore and download RootBrowser

https://play.google.com/store/apps/details?id=com.jrummy.root.browserfree&hl=en

ii) Open it and grant SuperUser access

iii) Now follow the steps

system->usr->keylayout

then you should see Generic.kl . Click on it then "Open as..."->Text file ->RB Text Editor

iv) Ok so now you should be somewhat careful . Scroll down till you find the following numbers

139, 158, 254

​

After you find them just put the "#" in front of the "key" word WITHOUT spaces. It should look like this

v) Save and exit

vi) Go to settings -> Display and Wallpaper -> Touch key light duration -> Always off

vii) Exit and restart your device.

Now once you restart the following should happen :

1)Back and appswitch button should not work/light at all.

2)You should have a fully working navigation bar.

3)Your Home button should work fine.

If anything from the above doesn't work as it should , make sure you followed the instructions correctly.

Important info: The screenshot button combination changed to Power+Volume down. (Thanks to [MENTION=4084293]amitb96[/MENTION])

The above steps should give your device some new feel more premium and if you followed the last tutorial on how to make your phone more stylish, this addition will look really good.​
