@gloobox - Thanks for info, he's hitting 28 no matter what
AFU, possibly this method (pay attention only to the flashing spoiler, and download attached files there) - https://linustechtips.com/main/topic/592...r-motherboards/
Or, AFU DOS ES >> V3.06.01 << I would not do this without programmer in hand, and confirmed OK backup made and ready to recover (and is this = true, then you don't need AFU, unless just testing method for info/others)

Sorry, flashing Asus BIOS does not have anything to do with flashing HP BIOS, so not sure what you are wanting me to get from that thread?
Error 7 is often need to reboot, or BIOS image is corrupted vs on-chip contents, bad mod, etc. Notice, reply right after first mention of error 7 is a new mod BIOS, and then again (but not tried with FPT, wen right to other tool, so you can't know if FPT would have gave error 7 then or not)
Error 28 is the issue here with Z620

@Lost_N_BIOS
Actually he used to bypass error 28 by sleeping bug.And I can bypass it too.
But error 7 was still prompted.

Btw,I had tried to take out battery of the mobo for several minutes,but failed.I think afu may help.

@gloobox - Good to hear sleep bug! We have not got that far here yet, I just asked him to test about sleep bug. So we shall see if same/same for him too. Sleep bug should bypass all protections, at least for BIOS region
Do you get error 7 if you make new dump in that state (after sleep bug invoked), then try to flash right back? Or make new dump right then, make test edit, try to flash back.

@Lost_N_BIOS
I tried to flash your modded BIOS but I got the error 28 when during flashing. It does not matter if jumper is in read only or write position. When I flashed it after sleeping mode I got the same error 7.

I am sorry. You are absolutelly right. I have checked all the FDs and I found out that when you flash a stock BIOS back the FD stays still unlocked.
In every case I always receive these same error message below as usually

"Error 28: Protected Range Registers are currently set by BIOS, preventing flash access.
Please contact the target system BIOS vendor for an option to disable Protected Range Registers."

No matter if flash jumper is set to read or write position.
I do not believe that Z620 could get modded BIOS with NVME support without removing of flash chip and flash it in a programmer.
If you have some other another idea let me know please.
Thank you a lot.

@Rabanik
Just tried the proper version of AFU,but I found many version didn't work on this machine.
Hope your feedback.

@gloobox - Yes, you're right, I didn't look that far back to see, it's same as you mentioned.
Yes, sometimes 280/368 etc can be removed, but then 26/28 can be left etc, I've only seen 7 when issue as I mentioned (bad edit, or previously AFU flashed BIOS), this is not due to FPRR (which is 26/28)
Sometimes could also be caused by BIOS Password applied, Secure Boot Enabled, TPM or Encryption enabled, this applies to these being true at time of dump or flash attempt, all that should be disabled/removed before dumping and then attempting to flash.
If any of that was enabled when dumped, toss that file, disable all, make a new dump, then move forward

Flash programmer, or AFU ES V3.06.01 and use of /GAN may be only option here (which I would not try without flash programmer, so then NULL)
Above true, if this method linked at 721 fails (Download tools attached, pay attention ONLY to the flashing method, last spoiler)
If you need that AFU mentioned above, let me know

@Lost_N_BIOS
@aGeoM
On flashrom,Did you know if there is any command about flash the part of the bios region?

@Rabanik @Lost_N_BIOS
I had tried many version of AFUwinx64 that all were failed.I just hit the order of dumping bios file.
Share with you

5.09.02.1384.07.B608.LV——4d- Error: Get block size error.

5.07.01——46-Error:Problem getting flash information.

I also tried AFU ES V3.06.01 and no success like you. The only way is the eeprom programmer :-)

Hello,

I have hp z820 and i tried use to Afu and dosen't work as well.

So i will try to programmer eeprom today, and i will send news.

Not sure what you guys are trying to flash @gloobox @Rabanik - I don't see mention of AFU ES V3.06.01 /GAN being used though, ohh what Rabanik mentioned this version, but no /GAN
gloobox, there is very few AFUWinx64 version that can flash mod BIOS, maybe only one or two, and all need /GAN that allow it when security is enabled.

@queirozfl - If you have programmer, it's always the easiest way, unless you already know other method, or see confirmed method outlined by others etc,

There is a way to mod for ASUS M5A97 LE R2.0

1. Download the ASUS M5A97 R2.0 bios (NON LE !!!)
2. Add the Nvme driver according to the instructions on Win-Raid
3. Save the file in * .rom format
4. Remove the BIOS chip from the motherboard
5. Load new bios via programmer https://www.youtube.com/watch?v=5NYe21nFSDI

hello,

I did dump from chip "winbond", edited .bin, and add the Nvme driver. So I did write direct to chip, but doesn't work, the computer doesn't start. I did rollback with the backup.

I recomend USB flash drive (non-bootable) for REFIND.

@Lost_N_BIOS
Hi, I have sent the HP motherboard from HZ Z620 to my friend who have experiences with desoldering parts and flashing of chips. I have your modded (NVME support added) BIOS but it is only BIOSREG of 11.5 MB size. I am affraid that I need an official modded of full size (16.7 MB) BIOS for it. Would you so nice and could you prepare it for me please? Or what is needed? I can not upload the J61_0396.bin BIOS because the file is larger that 6MB.
