Bios update = brick on Pavilion X2

[MarcYT]

PC came from Amazon Warehouse Deals with BIOS 04 and Win10 installed (original was 8.1).

Last BIOS ver. is 11revA and the little thing had some issues between trackpad and USB peripherals, so I tried to update from 04 to 11 (sp72717).

It chocked at 98%.

I created a USB thumb on another PC, by means of the same app that bricked my BIOS.

The Win+V (or Win+B) trick didn't work.  It keeps saying "The selected boot device failed" and/or "HP BIOS corrupted err.501".

The PC has not an hidden recovery partition (I guess that has gone when it was updated to Windows10).

Battery isn't user serviceable, any form of deep reset to reflash the Insyde BIOS require removing the battery, discharging the MB and working only on the power brick's juice. So that's a no go, i presume.

It seems there's not a way to force a reload of the failed update. I can still load boot, system menus. But BIOS didn't finish updating

SOLVED!!

I used HP PC Hardware Diagnostic 3-in-1 key (that's for HP technicians only but freely dowloadable), with the BIOS imgs extracted from the original sp (as my x2 is not among the "supported" machines).

Plus an AWFUL lot of patience and failed attempts.

But the little critter is alive and kicking. Yay!

Why HP releases crappy BIOS updates? I updated BIOS in SCORES of PCs without a hitch: this X2 and a HP dc6800 were the ONLY failures in my life.

Why the restore process has to be so freaking complicated, HP-Thecs-Only?

Why was I supposed to throw away a bricked PC, while a solution DOES exists?

... only the Gods of Ayteegard know that.
