@Sixindio: the reset is same as hard-reset of mobile; all data is wiped off, but the data on sdcard remains intact. All apps are gone though.
@NASIHA: search for adb and find suitable stuff, i cant just explain it to you here in a few lines. In brief, adb is an executable to connect to android phones and use the linux shell of the phone from PC.
@sleepy04: Thats what they do when you give the phone to the Service Center and I did not want my phone in their hands for the same reason - they do not wait for alternatives - but just reload the ROM and hand it back !
So, the next time we commit the same mistake we must have solutions/alternatives.
