After using my Pre 2 for 7 months, upgraded from 2.0 to 2.0.1 and finally to 2.1. Somehow my Pre 2 seems to be behaving weirdly, could be due to some patches. Therefore, it is time for me to do a fresh wipe to factory-mode except I will be using 2.1 ROM.
Things to take note, if you are not using an original HP/Palm battery, you will not be able to go into webOS Doctor mode. I have spent 2 hours+ with HP/Palm Support Care.
At the end of the 2.5 hours session, my Profile was not able to be restored as it requires a Specialist to do so. Looks like a callback is required to solve this issue.
