[deepesh.tickoo]

INTRODUCTION
This guide is for Ivan's 5.0 Lollipop AOSP ROM but will work with other ROMs as well.

FEATURES

• Pure AOSP feel.
• Many people prefer it, including me.
• Workaround for 'hardware key wakeup' bug.
• Can use Lollipop features like Screen Pinning easily.
• Looks cool

PREREQUISITES

• Ivan's Lollipop AOSP ROM.(May work on others too)
• MI3.(Again may work on others too)
• Root.
• ES File Explorer.(or any file manager with root access)

INSTRUCTIONS

• Enabling on-screen nav bar.
  1. Open ES File Explorer and grant su access.
  2. Go to system and open build.prop with ES Note Editor and add this line in the end:
     

     qemu.hw.mainkeys=0

  3. Save build.prop and reboot.
  4. Check if soft keys are enabled.
  5. If enabled successfully, proceed to next section.
• Disabling hardware capacitive keys.
  1. Go to system/usr/keylayout and open 'atmel-maxtouch.kl' with ES Note Editor.
  2. In the end of that file there will be following three lines:
     

     key 139    MENU    VIRTUAL
     key 102    HOME    VIRTUAL
     key 158    BACK    VIRTUAL

  3. Add a '#' before each line so it would look like this:
     

     #key 139    MENU    VIRTUAL
     #key 102    HOME    VIRTUAL
     #key 158    BACK    VIRTUAL

  4. Save the file and exit.
• Disabling capacitive key lights.
  1. Download Capacitive Buttons app from Play Store.
  2. Open it and grant su access.
  3. Select the first option i.e no brightness.
  4. Reboot

DONE

Thx for this mate.

I am unable to boot the system after enabling on-screen nav bar by editing build.prop...... Shows starting MI logo and then a blues flash and again restart. It goes into this loop.
As soon as I remove that "qemu.hw.mainkeys=0" from it, system is botting

For that you need to edit the jar files in framework, you can find a guide for that on xda. I could have done that myself but my exams are gonna start in a few days, and moreover I'm sick. ?

Can you tell me in detail what exactly you did and which file manager you used?

Hi,

I used ES File Explorer first to edit on phone and then rebooted. Phone didn't start so then I went into CWM recocry, pulled file by adb on my desktop, removed the line which I had inserted and then pushed file back to system. Gave 644 permission and rebooted. Device worked this time.

Lemme know if there is any other way. One thing I cld try is edit the file on desk and push through ADB. Earlier I had inserted required line with ES Explorer and editor.

Thanks in advanced.

Yea do try that and report, I think the ES method is messing with the build.prop permissions somehow!

 

[FcukBloat]

i used ES with no problems at all!

 

[deepesh.tickoo]

Same here, I too used ES without any issue, but I have faced certain problems with ES regarding saving system level files i edited and problems with proper permissions in the past.

Yup... It worked by this method. Flawless.
Enjoying lollipop to the fullest now. You guys are fantastic. Thx.

I've been using ES for this for over a year now...no problems...
Maybe a typo was at fault?

I guess the issue was with saving the file. May I know how you saved the edited build.prop file in ES Note Editor?
I would like to know this so that I would update that info in the thread, so that in future users can be more careful.

It worked great for me! Thank you!
Will there be a way to make the navbar transparant instead of black?
Thanks in advanced!

There might be by editing some png in framework-res.apk but I am not sure about which png file needs to be edited.
Although I can assure you that transparent nav-bar will only annoy you!
