HP iPAQ 5470
Founded in 1939, HP has become a worldwide technological company operating in 170 countries creating simple solutions for home and business from handheld computers and smartphones to full supercomputer infrastructures.
You will need to know the exact model or series of HP iPAQ you have, as the reset technique is different for many of the HTC units. If you are unable to locate the model information it can normally be found inside the battery compartment.
Once you have this information, just select your unit from the iPAQ PDA & SmartPhone Model List, and follow the reset instructions exactly.
