To reset the flash, power must be applied. So no.
There are tools in the shops and service centers to wipe the phone. Also, Kapersky may know a workaround.
Given the following story -> http://news.cnet.com/8301-30685_3-57327424-264/googler-android-antivirus-software-is-scareware-from-charlatans/ can I ask why you did this? Did you get scared into doing this?
Can someone tell me if it's possible to do a factory reset on my new phone without turning it on?
I loaded Kaspersky's Mobile Security program on it. As part of the installation it asked for a security code and rejected my first all numeric choice. I added some alphas and continued. When I went to check/amend the standard settings, it came up with an all numeric keypad and no way to enter alphas. Clicking in the data field brings up a Samsung keyboard but there's still no way to enter alphas.
