@Lost_N_BIOS - I only found this sticker on the connector

@Petoparac - Thanks, you can remove now if you want. One is LAN and one is bluetooth (I assume) Does this board have Bluetooth, if not, does it have two Ethernet ports?

@Lost_N_BIOS - It has two Ethernet ports + Bluetooth + wireless. Is it possible to see MAC addresses from Windows?

@Lost_N_BIOS yes, bad solder. now is working.... i modified with AIO tool other backup i was already have with Universal Bios backup toolkit 2.0 from here the link. then flashed it with Colibri (the w25q128jvsg chip). soldered (bad) in motherboard, it was doing the same simptoms than before (power on 1 second and shutdown), after i reinfroced the solder and worked OK. in the bios now showing ME version 11.7.0.1229. dont need to isolate/connect pins in G5400 cpu (because is a z370 perhaps). later i will test with i3 7100... sorry my bad english. thanks google translator.

Edit: just for confirming that I3 7100 and g5400 worked like a charm without connect or isolate any pins in Asrock Z370 Pro4. this is the steps worked for me: backup original bios, downgrade ME to 11.7.0.1229 and add cpu microcode in bios (AIO tool do it for me), desolder eeprom from mainboard and back solder again after flashing using ch341a programmer with colibri v1.0.1 software.

@Petoparac - Yes, please check via CMD >> IPCONFIG /ALL
Test both Ethernet ports please, do they function, you can connect to internet? If yes, then it's OK and I don't need to fix, some BIOS have these stored in GbE and some don't, the BIOS you sent me has generic 88:88:88:88:87:88 in GbE which is what caught my eye

* Edit - This BIOS is problematic for this mod, and I need to work around (ie find working edit method, dance etc) to get past the problem without it happening, so may take me some time. This may be why all your previous attempts = brick too
During patching, the PCIE patch step causes a padding file to be removed above microcode volume in the main DXE volume, this often = brick. No matter what tool is used this happens, CoffeeTime, Revlaay's AIO tool, PCIE Patcher 1.4 etc.
I will work around this by removing many modules and see if I can get that part of the edit in without it happening, then do the rest after inserting modules back.
I bet this is the problem all along, I have to work around this same issue with many BIOS when doing NVME insert or microcode updates (usually this more than anything causes it)

* Edit 2 - @Petoparac - Before I spend more hours to try to work around this issue, lets confirm it's an issue or not
Please test this BIOS. Erase chip, blank check, then open file, write and verify. Then remove ALL power from the board, remove PSU cables, short power on pins for 10-15 seconds, then let sit for 1+ minute with zero power.
Then see if you can boot your old CPU first, if so, shut down, clear CMOS, put in new CPU and then see if you can boot to BIOS or not. If old CPU works, but new CPU does not, then padding concern I had is not part of the problem and you need to check your isolation/connect areas on the CPU pads
Also, if Ethernet not working, let me know and after this we'll fix if necessary (programmer not required for that, we can do with FPT)

@guspaz - great to hear it you got it all sorted out and working now!

@Lost_N_BIOS - Only one Ethernet port works for me and I turned off the other in the BIOS because it reported some error. I'll post a picture here. I have one more identical BIOS chip and it serves me for testing .

@Petoparac - Looks like neither MAC for Ethernet is stored in BIOS then, since you have working one above and that MAC ID is not in BIOS, they must be stored directly in chip. Your other one probably needs MAC Fixed in it, or FW fixed etc.
See my edits above, I made you BIOS to test, to see if the concern I had means I need to spend more hours to work around, or not. Let me know

@Lost_N_BIOS - I've read the whole post and I'll follow your instructions so I'll let you know if it works. You invest a lot of time and knowledge to help me and thank you very much for that.
-----------------------

@Lost_N_BIOS - I tried the BIOS you sent me and it won't work. The fans spinning and 00 code is written on the motherboard. I did everything according to your instructions. I only tried it with an old CPU.

@Petoparac - Thanks for testing. Then this failure must be due to the padding issue I mentioned, I'll have to work around it - please wait, I will try to get done soon

* Edit - @Petoparac - Please test, should work now - http://s000.tinyupload.com/index.php?fil...969625484844512
I included two files here, one used non-ideal method, explained in txt, but I think first one should work OK anyway but sending both in case you need to test 2nd for some reason (first should work )

@dsanke - When you guys do/discuss "port Z370/Z390" BIOS into Z170/Z270, what is really going on for that kind of edit?
Is it just a direct "BIOS region" (entire) swap from Z370/Z390 into the older BIOS? Or is only certain parts of the BIOS region swapped over?
If it is entire BIOS region swap, how do you know what boards/BIOS are compatible for swapping in, is it just basic looking to see if the PCB's look same/similar on the donor board compared to the target board?

---

@Lost_N_BIOS - I tried both BIOS files you sent me and they behave the same as the first one. I used the Colibri 1.0.1.61 software and the CH341A programmer. Give me some time to take the motherboard out of the case and try everything on the table. Would it be better to modify the original bios downloaded from the Asus website?

@PCGH_Torsten - Thanks for the info. Sounds messy, compared to just swap of BIOS region and fix DMI strings etc
I'll leave this kind of edits to the actual pro's

@Petoparac - No, it would not be better to mod the original stock BIOS, I am not sure why that is mentioned in guides other than easier to mod and share maybe?
But just in case, maybe NVRAM causes issue sometimes, I will make you stock tester below. Clear CMOS should sort that out anyway, if an issue
You are erasing, blank check, then open file write/verify correct? If yes, then confirm your CPU padding isolate/connect stuff is OK. You did to the power drain and wait correct?

Please test once more before tearing down, with first BIOS from 1059 package (not the one in non-ideal folder), and this time after drain/wait, clear CMOS and remove all but one stick of memory, then try and see if anything changes.
When you recover, do you write back with colibri and it's OK? If yes, then it's OK, I was starting to wonder if you should use ASProgrammer instead, but if you are recovering with Colibri write is working properly.
This came to mind because before Colibri I think ASProgrammer was only one I know that wrote to this chip properly.

Here is stock modified BIOS x2 to test, I suggest testing the one with PadWk in name first. I also fixed GbE in these BIOS, so maybe your other LAN will work now too

DO you have ANY previous BIOS backups before you did ANYTHING to BIOS? This can be made with AFU, FPT, EZ Flash, programmer etc, does not matter.
I ask because your GBE was messed up, your serial, UUID etc data is missing from both locations in the programmer dump you sent me, so it looks like you messed up this BIOS in a few ways before you dumped and sent to me.
So, needless to say, none of that will be in these stock tests, nor any previous I sent you, because it's gone by default. I only noticed, aside from the GbE, when I went to transfer back info into stock edit just now
Maybe this, along with something else messed up I didn't notice, is causing all these to fail? If the stock mod one works, then this may be the case. Send me any previous BIOS backup you have BEFORE you did anything to BIOS, if you have one, then I can fix your serial, UUID etc.
If you never made any backups like that at any point in the past, then you'll have to send me images of all stickers on your board and I will recreate you new UUID, and put serial back etc.

@Lost_N_BIOS - I changed the BIOS a couple of months ago and I can't remember if I did it via USB or via a programmer. Since then, I haven't changed or modified anything in the BIOS except setting the USB ports and turning off one LAN port. I have not backed up the BIOS earlier and the file I sent you has been read from the chip and has not been changed or modified. My attempts to modify the BIOS were with the BIOS downloaded from the Asus website. It’s the same bios I have written into the chip for the first time and the computer started up without any problem. I will try to read the chip with different software again and send you the files.
Of course, I will do everything again according to your instructions and I will let you know if it works or not.
* Edit - When I take the motherboard out of the case, I will take pictures of all the stickers and send them to you.

@Petoparac - There is the problem, serial, UUID, MAC wise I mean, you flashed stock BIOS with programmer, this erases all your board specific data, that's why I asked if you had ANY previous BIOS backup BEFORE you did anything.
If you do not have this, then we can only recreate a new UUID and guess the first part of your in-BIOS serial to add onto the actual serial. None of this has anything to do with BIOS working with any CPU though, this just an aside thing we need to fix.
I do not need any new dump from chip with programmer, you already sent one to me

Did you test the BIOS above yet?

@Lost_N_BIOS - I tried everything today and had no success. Something weird is going on with my motherboard and I don’t know what it is. I tried all the files you sent me and nothing worked, only the fans spinning on the maximum speed and that’s it. After that, I use the BIOS I sent you and write in the chip, and then the situation was the same only the LED on the CPU came on. (The POST State LEDs provide the status of these key components during POST (Power-On-Self Test): CPU, memory, VGA card, and hard disk drives. If an error is found, the critical component's LED stays lit up until the problem is solved.) I tried to do a USB BIOS flashback and all the same again. Then I return the chip with which everything worked and from which I read the BIOS and the computer starts normally. I have two chips, one I don’t touch and the other I use to try out all these BIOS. Honestly, now I really don't understand anything and I don't know what to do next. Maybe to buy another chip and try again.
I have a jumper on the board that says VBOOT_TEST and the manual don't say anything about it, does it perhaps have anything to do with bios?
