How to HARD RESET POCKET PC DEVICES!!!
As sad as it may sound, there will come a time when you have to hard (or full) reset your Pocket PC. To hard reset a device means to restore the device back to it's original settings, just like it was when it came out of the box. You usually need to hard reset the device when you are having problems that a simple soft reset will not fix, if you want to sell the device and clear all your personal information off of it, or if you just feel lucky. There are a few things to note before completing this task. For one, make sure you truly want to do a hard reset. Back up all your information just in case you feel like you want to take a step back. Secondly, understand that even if you do a hard reset information in the ROM (on iPAQs it's known as the iPAQ File Store) will still exist. You'll want to delete this information manually if needed. Third, if you are trying to hard reset your device because you forgot your password, some device will have the password stick even after a hard reset. To truly get past this you will have to enter the password incorrectly or answer hints incorrectly a certain amount of times before it commits to a self-destruct process performing a hard reset on itself. And lastly, we here at Pocket PC Addict care about our Addicts, but we unfortunately cannot take responsibility for anything that you do. Please do this at your own risk.
