Just to remind, the correct procedure to flash:
(1) Burn ISO to a disc.
(2) Unplug non-related HDD drives from ur system and leave only the target drive and the CD/DVD drive which needs to boot up the CD.
(3) Set BIOS to boot from CD/DVD
(4) CD boots up, read the text, press F10.
(5) Press A,B,C depends on which model.
(6) Press any key to shutdown the PC.
(7) Now, this step i see most people didn't do. The 'CYCLE POWER' thingy.
- switch off ur main power switch.
- unplug the PC power.
- Press and HOLD the power button for 10 seconds.
(8) Plug in ur power supply.
(9) Power on main switch.
I believe the reason for step (7) is to clear off some static electric still remains in the mobo/hdd or something like that. Better safe than sorry.
static doesn't need 10seconds to discharge.. I think it's for discharging the capacitors from the PSU..
