add virtual serial number to the system

[MOHAMMAD RASIM]

Hi,

I'm trying to install an app that needs to read the serial number of the device to allow registration.

It reads the (ro.serialno) value but this value requires the following sysfs path to exist (/sys/class/android_usb/android0/iSerial) which is not available in an X86 install of android.

What my way around this? how can i tell the kernel to create this device for me (virtually)?

Regards

Could you just set that property (by root)?

setprop ro.serialno 12345678

Nope, I can't

x86:/ # setprop ro.serialno 1234567890
setprop: failed to set property 'ro.serialno' to '1234567890'

You have to do this from init.sh/init.rc

Doesn;t make a difference, I added the command in the init_misc function and still after the virtual machine is booted I don't see the value saved (tested using getprop command).

The simplest way is to add androidboot.serialno=xxx
to kernel cmdline.

this is seem a solution to make the device unique, but when we replicate example on VM, the same serialno=xxx is used the same accross vm, make the software we use inside the Android X86, can be replicated ..
any idea about this, I know this will be unusable if developers read this, and still able to do "things" but at least some users who just replicate our rom, can be detected.
