I bricked my netbook while downgrading BIOS to a04. Finally after spending nearly 15 days trying brought the netbook back to life. I just want to share my experience:
1. USB floppy drive required.
2. Bricked Netbook can be powered with 'End' + Power switch. No need Fn + End, at least in my case.
3. I had made bootable floppy with Crisdisk using minidos system. Floppy contained only 03 files - minidos.sys, phlash16.exe and of course BIOS.WPH
4. Various types of BIOS files used. Floppy drive used to make sounds, but no success.
5.I remembered having flashed with A06 while the netbook was in working condition. Therefore it must have backed up it's ROM file somewhere. It did not flash finally as the existing file was not newer.
6. I removed the keyboard of bricked netbook, removed the hard disk, hooked up the hard disk in another desktop. Copied the BIOS.BAK from the hard disk's windows/Temp/Winflash/DOS to the bootable floppy. Renamed BIOS.WPH.
7. Final touch - Battery removed, power cord removed, attached the USB floppy drive with the bootable floppy inside with the renamed BIOS.BAK to BIOS.WPH, pressed 'End' button, connected the power cord, released 'End' button + Pressed Power Button once. One Beep, pause, Floppy Drive accessed, multiple beeps with running of Floppy drive. Finally the power LED was off automatically. After waiting for nearly 10 minutes, removed the floppy drive, removed the power cord, waited for 30 sec to 01 min, connected the power cord, pressed Power button - the netbook is online.
