I was at BIOS version F16, when I tried to follow a good guide that I saw in here, but know my laptop don't boot anymore, I`m trying to boot using a HP_TOOLS usb drive with win+b key combination. but with no luck. I really need a help of you guys, I`ve pretty sure that I`m doing something wrong. the only file I put in usb was 01651.fd and the same file renamed to 01651.BIN. this is the first time that happened to me. I hope with your help I could fix this and be deeply grateful. Thanks in advance.
