You can enable the R&D mode by passing the "--enable-rd-mode" flag to flasher-3.0.

You must use a Linux or a Mac OS X computer to enable R&D Mode - the Windows update wizard will not allow you to enable/disable R&D Mode. Although, the Windows flasher will disable R&D Mode if you use it to reflash a device that has R&D Mode already on.

What R&D Mode does

  • "sudo gainroot" in the console can be used, without installing anything extra, to gain a root shell.
  • The power button turns on the tablet with one press, as opposed to the usual behavior where you have to hold the power button for the tablet to power up.

R&D Mode flags

You can enable some R&D mode flags (flasher-3.0 --set-rd-flags=<flag>) for various features:

  • "no-lifeguard-reset" - disables the lifeguard process (lifeguard reboots the device when an important system process crashes)
  • "serial-console" - enables the serial console (the serial port pins are next to the battery) and causes a shorter battery life.
  • "no-omap-wd" - disables the watchdog on the OMAP processor.
  • "no-retu-wd" - disables the watchdog on retu.
  • "no-usb-timeout" ???
