Ok.
I did the procedure today.
1. The backup / restore thing doesn't work. I.e. it does make the backup and it says it has restored it successfully but it doesn't restore it. You will need to input your parameters by hand.
2. Normal Reset just resets your settings. It does NOT wipe out history.
3. You need to do a "FACTORY" reset to wipe out all data.
4. Once you did a factory reset and put all your data back in, the
device will be fast again in transferring the data. The previous data stored in the software will NOT be affected.
5. Warning! When you do Factory reset, you will loose total puff count... mine was 40650 and now its 00003
Hope this helps.
