Asus K55A UEFI BIOS flash recovery methods after BSOD failure while programming BIOS

I have an Asus K55A notebook with something that seems to be a bricked BIOS, after a failed flash attempt while using their damn Asus Flash Utility in Win7 X64.(A tool which is actually incapable of writing the new BIOS into the flash area while running an X64 OS!)


It had however saved the original BIOS 404 to a hard drive as a hidden file on the root folder.
I wanted the BIOS 407 version in order for my machine to properly detect 12GB or 16GB of RAM.
Also my Core I5 based machine was unable to properly fast boot without the UEFI CSM option enabled in the BIOS.It would loop continuously into BIOS after restarting with BIOS 404 and no UEFI CSM mode enabled.


The motherboard revision is K55VD rev 3.1.


With the PXE option disabled in the BIOS which means no USB3 DOS mode support one of my ADATA USB 3.0 sticks would disconnect randomly, while the other two were working well.


Is there any possibility to reflash the BIOS in DOS mode using some sort of USB Flash Recovery Utility like the one that HP has, namely the HP USB Recovery Flash Disk Utility?


Does Asus have any similar USB flash recovery bootable software solution?


Why is the HP Recovery tool not installing to the USB stick in Windows 7 X64?


It does power up but nothing appears on the display.I already tried any key combination, resetting the CMOS battery, Ctrl+Home+Power, ALT+F2, ...
no luck and still no image on the display.


I was afraid to use the Asus internal EZ Flash program even though it was seeing the correct version of the newer BIOS 407 because it would not save the original BIOS, somebody working for Asus told me to update using their Windows based flash utility, and that proved to be a total disaster and a big mistake, after three complete erase/write loops, it gave me a blue screen while erasing for a forth time and my machine was gone.


Should I take it to an Asus certified repair laptop service?


Is it possible to flash the soldered BIOS by connecting a set of specialized
pliers with many specialized connectors to an external programmer in order to flash the correct BIOS?


There are only two certified Asus repair shops in my area and both are 50 miles away from my location.


Please help me!


Any suggestions are welcome and highly appreciated!


Thank you very much!
