ORIGINAL_POST

After installing android tools

adb and fastboot

on my Linux desktop,

I installed Android 4.2.2 (Cyanogenmod distribution) following the steps suggested by the article

install-sony-live-with-walkman-wt19i-android-4-2

NB: I also tested an other Android distribution (Paranoid Android),

but I was not able to switch the setting menu from tablet layout to a smartphone layout
