hi.. i read about how to backup my handphone's flash using optiflash.. had done it successfully.. but one thing to clearify, what are the ranges? is it to specify the ranges to backup only?

but what i want is a full backup of every range... in case of anything happen when i try to flash with another firmware, can i still use the backup that i specified the ranges?

0x00000000 - 0x00000617
0x00004000 - 0x00007a43
0x00010000 - 0x00576a53
0x00700000 - 0x00cbd713
