dm4-1165dx not booting after bios update

[foforivera]

I recently tried to update the bios on a DM4-1165dx from F.23 to F.27 as I recently formated the disk with windows 7 pro, I downloaded all the requiered drivers and everything was running smoothly until I ran the bios update tool, followed the instructions as said, waited for more than 5, noticed that the update window dissapeared then the fans started working at high speed. This lasted around 13 minutes. (now being almost 20 minutes) the bottom of the laptop was really hot. The mouse wasnt responding, neither did the keyboard (tried to get taskman to cancel the process). Waited 5 more minutes until I decided to pull the power cord then it just turned off.

Haven't been able to turn it on.

Already tried:

1.- removing the battery, waiting, power, windows+b, HP_TOOLS usb

2.- removing cmos battery, removing memory modules installing new ones.

The blinking leds were blinking 2 times acording to this:

Troubleshooting LED Blinking Lights

is a problem with the bios, I need help troubleshooting this issue as the bios is so new I haven't found any troubleshooting available.

PLEASE HELP!

You can boot and recovery to your previously installed BIOS version.

broken link

Is it the windows power b? if it is, it doesnt do anything

[SCTaylor]

yes it is windows button and b. What happened when you did that?

[foforivera]

Absolutely nothing, I don't have the HP_TOOLS partition, I did the other option the USB UEFI HP_TOOLS thing and nothing either. It just turns on, gives the light indications, the fan turns on and in a matter of 1 or 2 minutes it turns off

[SCTaylor]

Can it get into BIOS (F10) or Recovery Manager (F11)?

[foforivera]

Nothing blank screen (black screen for that matter) led blinking nothing after that

[SCTaylor]

Have you tried to start, press F9, and select your USB drive with the HP_TOOLS on it?

[foforivera]

will try it...
