@Rabanik - Don’t enable S5, use S3 (leave S5 disabled), and then use “Sleep” button in windows, not Hibernate.
36 only is what you need, put rest in default position. Put jumper on there, reboot twice and then do flash again from windows.
If you cannot get it, then you need flash programmer.
@aGeoM :
According to my recent tests the Flashrom tool may neither need a patched old Rufus version nor the diskcopy.dll file.
I just have done a backup of the meanwhile updated BIOS Region after having created a new bootable USB Flash Drive by using the currently latest unpatched Rufus v3.10 and choosing the option "FREEDOS" instead of "DOS" and it worked!
Look here:
Can you confirm this find?
@LOST_N_BIOS
I disabled S5 mode in BIOS.
I tried to reflash the dumped BIOS back after sleeping mode but I got the Error 7 message again.
So there are only two choices left. Flashing using of jumper 36 or the programator which I do not have.
Tell me please why the dumped BIOS (11 468 600bytes) differs when I compare it with the original one (16 777 216 bytes) downloaded from HP sites? Both versions in my PC or the downloade one are the same latest version J61_0396
And when I successed with flashing after sleeping mode. Which BIOS to modify for NVME support? The dumped or original from HP sites?
Edit:
When I put short the BIOS jumper 36 and rebooted twice and I got during flashing the Error 28 message again 
thank you
procedure to flash tuf x570 gaming plus no work for me
all three
@pipes80 :
The problem is the size (32MB) and the structure of the BIOS.
The only tool I know to be able to get a modded 32MB BIOS properly flashed is the Flashrom one. I am pretty sure, that it will work with 32bit ASUS BIOSes as well.
You can find my guide within the ASRock mainboards section of the start post. You can use it at own risk.
Why do you want to update a freshly released BIOS?
@pipes80
Did you remove capsule header from you bios? You should post some SS or photo for more information.
@Fernando
Nice find. 
It seams to be working, so less hassle for creating the boot from USB.
wich version download? flashrom for dos or is indifferent?
@pipes80 :
Did you read my guide about the usage of the Flashrom tool? You will find everything within the "Flashrom Utilities", which is attached to the start post.
Thanks bug no work that procedure too
@pipes80 :
What means "not work that procedure"?
What have you done and what happened? Did you get any error message? If yes, which one?
no take error, only recover bios after boot and microcode cpu it’s same bios original version
@pipes80 :
So has the flashing procedure been successful and without any error message?
If yes, how did you check, that the updated CPU Microcodes haven’t been used after having flashed the modded BIOS?
Can Watch in BIOS cpu configurazione or hwinfo
@pipes80 :
If you have followed my guide and replaced the stock BIOS Region by the updated one, it seems impossible to me, that the CPU now still uses the Microcodes of the stock BIOS.
Are you really sure, that the flashing procedure was successful?
@ Lost_N_BIOS
Hi,
I have successed with service jumper ON of Flash Descriptor for dumping and writting it back.
I am attaching the dumped BIOS as well because I think that my mod for NVME support failed. I have used both utilities UEFITool and MMTool (and various versions of both) with the same result.
I do not have there a correct padding (blue circle) which should be there as in bottom area of the attached picture.
Thank you a lot for patience with me.

you talk of this Annex?
How to dump the BIOS Region and
how to flash a modded AMI UEFI BIOS
by using the Flashrom tool
@pipes80 :
If your question was addressed to me, my answer is: Yes!
Please write what you have done and what happened.
By the way: The UBU tool is not yet available to update the CPU Microcode of both BIOS parts. This may be the reason why you didn’t see the updated Microcodes after having flashed the UBU modded BIOS.
with the latest version of ubu inserted in 1.77 the update of the microcode worked
