O2 XDA IIs hard reset

Resetting the O2 XDA IIs

You can perform a soft reset or a full reset. During a soft reset, the device is restarted and
only some data in opened programs may be lost. However, a full reset turns the battery off,
returns the device to its original factory settings, and deletes all programs, files, contacts and
other information you have saved to the device. Therefore, it is extremely important to back up
data to a storage card or your computer on a regular basis in the event that a full reset has to
be performed.

To perform a soft reset:

If your O2 XDA IIs responds slowly, stops responding, or freezes, you can soft reset it.
A soft reset causes the O2 XDA IIs to restart and re-adjust memory allocation. Unsaved
data in any opened applications may be lost. Use the stylus to press and hold the Reset button,
as shown bellow.

To perform a full reset:

A full device reset clears memory, deletes all data and restores the O2 XDA IIs to itsdefault settings.

Programs installed at the factory remain,
erasing all data that you have created and programs you
have installed.
Press and hold the power button, and then use the stylus to
press the soft reset button at the same time. Be sure you
have backed up all your data in a SD card or on your PC
before performing a full reset.
