One big warning: do NOT install the
cr3 Coolreader that you find in that i62ML related thread on a M92 ... it will freeze your device as soon as you try to use the joystick (you need to make a hard-reboot -> first press the reset button in the hole on the back side of the M92 and afterwards press the usual "power-on" button).
The
cr3 Coolreader that you can find there reports exactly the same version as the one that is now present on M92.
