I was not so lucky.
Having disconnected everything, I tried to boot on usb key with valid bios, but nothing ...

so friends, apparently my bios burned out ...

the same :/

Well now. I thought *all* Intel 300 series chipsets are only for CSME v12. Also, reading through those comments made me glad I didn't try to update ME firmware without PlutoManiac's approval by him posting a verified version in the first post.

Finally, isn't GIGABYTE this one corp that promises lifetime warranty on its products? Try its customer support, maybe the people there will exchange your bricked motherboard for free...

Looks like no more ME firmware updates until Plutomanic returns.
The "firmware" posted by @westlake, the v12 files, are in fact not firmware files at all, luckily I tried to open them with FIT before flashing.

11.8.71.3630 works fine on my Asus Z170 Deluxe.

Well, it must be a dirty firmware that only works on some boards.

Intel CSME 11.8 Corporate PCH-H D, A Firmware v11.8.71.3630 was verified by plutomaniac. It has the same Version Control Number -> 284 and gpvecchi certifies that it works for ASUS motherboards.
However, considering that the VCN gets incremented if there is a security fix, a significant firmware change or a new feature addition is no hurry until additional information regarding this release appears.

On my Asus TUF Z370 Pro Gaming motherboard with last bios 2203 had trouble with v11.8.71.3630 (no boot until I reset cmos), it works if I don't set XMP or put any value for FSB (only works on Auto, not even 100 mhz). Reverted to Intel CSME 11.8 Consumer PCH-H D,A Firmware v11.8.70.3626 fixed it.

Gentlemen, this is f@@ked up !! How is this even possible ?? Someone creates software that kills bios on our motherboards! Who is generally responsible for this act of intentional wrecking ???

The main problem i see with intel and the mainboard vendors. intel has built in many, many security holes into this ME/TXE stuff and did not create an easy way for the ordinary home user to upgrade. For TXE it is pretty much impossible to update.
The mainboard vendors do a lousy job in maintaining recent fixes.
At least linux and lately MS offer microcode updates within the OS.
For the ME/TXE part they leave us mostly alone until maybe a lawsuit can force them to have to offer updates for a given number of years.

I just updated my Z370 board to 11.8.71.3630 without issue.

Can confirm successful upgrade on a ASUS MAXIMUS_VIII_HERO (Z170).
