I'm planning to reinstall my PDA, HP iPAQ 6365. But so far I do not know how to reinstall my PDA. Please explain me how to reinstall a PDA correctly? Because my warranty is up. Answer: Why do you need to reinstall? With the hard reset, everything is back to the original. Your PDA will look like new. For information, the pocket PC operating system is placed in ROM. Can not be removed or deleted, except for the additional programs are installed there, or by doing a flash of his ROM. So, if you just want to restore all the settings as to its original condition, just hard reset it. How? Take a look at the PDA manual. There must be a way.
