Last night, I went to flash by Bios using above file on a G56-129WM. After bricking the BIOS, I found there are many other complaints of similar issues. I have flashed 100's of BIOS, and I have to say this is first on I have bricked. There are many posts of similar users who have done the same thing.
Personally, with my experiance doing BIOS upgrades (I volunteer with school donation programs) and reading all the complaints I personally think this is a way for HP to get users to get new laptops.
There is no reason a BIOS update should brick the BIOS. NONE!!!! Sole exception is if power is cut durring the flash.
I have also read that many users have tried to do a manual BIOS recovery with a USB stick.
Is seams there are many p2p users claiming to be HP experts that are givin gbad advise.
I have read at least 1 dozen threads were users finally gave up.
I am sorry to say, I am one.
I have tried ever available BIOS bin file on my USB stick with HP_TOOLS
There are no availble .SIG files, but seams this is only required for earlier models.
Win + B + Power results in a USB flashing for 5 min, but no change to the black screen.
I see the HP logo at boot, but then screen goes black.
I have to say Dell lost my recomendation with all their popping capacitors, but this is something HP has control over. If HP technitions are not smart enough to create a BIOSflash kit (something the PC industry has been doing for 20 years), they should go home and let Lenovo dominate the market.
For those that have gotten to the end of my Sticky, if there is anything else I can try that has worked please provide a link.
thanks
