Thanks for the answer. i didn't think it was that easy. However i'm not ready to root my phone. (Warranty, risks etc...)
I've manage to open, read, copy to SD card and modify with text editor, but how can i push it back (and not loose modifications after reboot)
(adb, something else? )
anyway. I've check the build.prop and found i need to change the ro.product.model= xxx
Now i just need to push it back. Could ADB or Fastboot do it ?
Any idea on how device identification works when it's not an android phone ?
