This is an article from the old midgard wiki that hasn't yet been fully updated for this wiki, please update it.
Please see the talk page for discussion.


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" ???
