HP Pavilion DV7 bios recovery

hello!

my biosflash went wrong and now i get nothing when i boot, just a black screen and a running computer...
ive looked up some information left and right but as of yet am still unable to recover the bios.

so far, ive gotten in bios recovery (hold win+B at startup). but it gives me one or two beeps according to the format ive used to format the usb with. (fat vs fat32). when i remove the usb the beeping stops...

im using a HP Pavilion DV7-1040ew

Bios Page:
http://h10025.www1.hp.com/ewfrf/wc/softw...3&sw_lang=

The phoenixtool said i had to rename the bios file to f3.bin but the beeping continued.... so im at quite a loss right now..... not even sure which one of the three bios files (in the latest bios update) to use...

im assuming its an insyde bios, since the files are ending in fd.

any help is greatly appreciated,

thanks!
