My T1 is only around 6 months old but is becoming increasingly balky. I get frequent screen freezes for no obvious reason, requiring a reset (ie pushing the reset button) to fix each time. I have to keep a safety pin attached to the Reader cover so I have the necessary implement easily to hand. Doing this 4 or 5 times an hour is not what I signed up for ! Before returning it for a warranty repair or replacement, I want to try a complete software refresh, but how do I do this ? Ideally I want to flatten the thing and reload from the web somehow - is that what's meant by a soft or hard reset (what's the difference) ? If so, how do I do these please ?
