@arc1880 - For Gigabyte, they do not enable any FD locks, or BIOS Lock etc. As you can see in the IFR output you posted above >>

The error 7 is due to you need to reboot and do again, or do in windows not DOS, or "FreeDOS" is not working (or Rufus method) try Win98 SE instead, or you may have messed something up with a previous AFU BIOS flash.
Here, follow stop #1-2 only (USB may look empty, this is OK) - <Request> Flagship X470 Gaming 7 Wifi Motherboard BIOS Fix

Yes, you can boot EFI/UEFI to USB on your Gigabyte Z87, you need to set OS Type to Win8 and then at boot menu page choose UEFI USB by name (not normal "USB" entry), or you can directly choose this on boot override at exit page too (after you apply the UEFI OS Type setting first, then reboot back to BIOS)
Secure Boot can be disabled by setting OS Type to Win7 or other. USB needs to be initialized as GPT if you want to boot UEFI, if you want to boot legacy/non-UEFI it needs to be initialized as MBR

Not sure what you're main issue is anymore, sorry? You do not have to boot to UEFI USB For anything we've been discussing, FPT if needed can be ran from DOS on non UEFI USB, or windows (ideal, since you are having issues)
Plus you have a flash programmer, and I assumed you were fixing BIOS that way, then needed to do the backup (which you can do with KB and hotkeys I mentioned) So I'm lost as to what you're trying to do, and why etc
At post #613, it looks like you are still bricked?? If yes, fix the main BIOS first with flash programmer, that's a must before you can do anything else here.

For #3 - what software are you using when you try to erase? Yes, maybe extension is causing issue, due to power loss, don't use it and try again.
Sometimes you may need to connect main power (4/8 pin + 24 pin), sometimes you need it removed, usually though, if you can read, you can write
But, I would go ahead and connect both main power cables and try again

#4 - Find old PS/2 keyboard, this is the way (some USB will NEVER work, and sometimes NO USB Will work)
The info I gave you above is correct, what you mention (ALT+F12) is only for old Award BIOS - ALT+F10 you mentioned, which I already told you is the way to do it, this is for UEFI BIOS (Plus all I mentioned at post #611)

If you want to buy best SOIC8 clip, you need Dupont cables M/F long enough to reach or daisy-chain, plus Pomona 5250 clip - If you can read chip now, you don't necessarily need this.

Hello,
ASUS Z17-WS motherboard
https://www.asus.com/Motherboards/Z170-WS/HelpDesk_BIOS/
I would like to buy:
1. a BIOS chip (Winbond-25Q128FVIQ1529) for motherboard
http://www.bios-chip24.com/epages/637300...roducts%2F32148
2. a CH341A programmer
https://www.aliexpress.com/i/32961518523.html
My problem is that I lost the original BIOS chip (actually the courier lost the package) sent for rewriting to a company, but I saved SN, UUID (using dmidecode in Linux) and the two MAC addresses for the network cards (from Linux file /etc/udev/rules.d/70-persistent-net.rules).
I read the user guide for the CH341A programmer but it is unclear to me how to transfer the two MAC addresses because FD44Editor only shows me the first MAC address?

---

@Lost_N_BIOS

Hello again, I hope you're doing good, it's been some time since the last time I checked here, sorry for not replying to your post, I lost hope in fixing my laptop and just forgot about it till now, I managed to buy a same model motherboard from Ali Express, and my laptop is working now as it should, the only thing left is to unlock my BIOS, that's when I remembered you.

I used CH341A programmer to read and backup my BIOS, I saved many versions of my BIOS just in case, one as W25Q64BV and the other as W25Q64FV, both using the 1.34 version, then I remembered Colibri and used it to save as W25Q64BV, W25Q64FV and GD25Q64 (because this is what both softwares detect as the chip ID).

Can you help me unlock my BIOS? if yes which one of those backups do you need? and can I send it to you as PM instead of here in public?

Thanks a lot for everything you're doing to help the community.

@arc1880 - For MX25L6473E - Use CH341A v1.31(1.4) (CH341AFree) - choose type 25 and correct BIOS size
You can erase with this version, if not, try 1.18 version to erase (or colibri), but you should be able to erase and black check with the version mentioned above.

@ibsajc - Yes, maybe that is old "random.txt" file, here is my current notes from that file I keep now >>
For W25Q128FV you need to use 1.18 version CH341A software (for valid read only), or use ASProgrammer 1.41, otherwise other versions always fail (at read sometimes, but write always).
For write to this chip, only Colibri (included below) or ASProgrammer has been confirmed working here by others
Personal testing here (Asprogrammer) - Bricked Asus Z170-AR

Thanks for the heads up though! Can you send me colibri 1.0.1.62 please, I only have 1.0.1.61

@qattos - Good to hear you have a working system now! Sorry you had to buy a new board though! Lets fix the old one too, that way you can resell it?

On the new system/BIOS unlock, please make a thread with the full model, link to stock BIOS, and tell me what is the actual BIOS chip ID you read off the chip with your eyes (Then I can tell you which dump I want, and what you should write with)
Programmer may not even be needed to unlock BIOS. And yes, you can send me file in PM once it's time, no worries
I only have that in my signature because it's hard to try and help with BIOS in PM, can't keep track of what's going on, what's been discussed, what model we're talking etc

You're welcome, and thank you too for the praise and kind words!!

@Lost_N_BIOS - Thank you so much for the reply.
Yeah my old motherboard had 3 shorted components, I will order them and try to replace them and see if it works, I'll let you know if that happens.

I have already made a thread with all necessary info, you can find it here:
[REQUEST] Lenovo Y520-15IKBN BIOS unlock BIOS ID: 25B64CSIG

And no worries, take as much time as you need, thank you so much.

@ibsajc - Ohh, OK, sorry I thought you meant you had used .62 in your test.
Would be nice to get .63 instead of .62, but I don't want to register somewhere just to get it

@quattos - Ohh, hmmm, I did not know the other board has shorted out items, that's not good
Looks like incorrect ID there, but I'll jump in your thread and check in case you made a typo in title.

@ibsajc - Please use 25.0 as mentioned, newer can cause issues on BIOS rebuild. Probably not in this case due to where you are editing, but I did not check if that second volume with FD44 module has any problems when using 28 or not.
The padding and GbE module should not be an issue, but that FD44 module inside volume may be, so best to stick with 25.0 until you know how to check to be sure it's OK. Best practices, you know, until you know how to check post-edit vs pre-edit for issues.

For doing the actual edit with UEFITool, you need to extract only #1 from davidm71's BIOS, the other two # below, you edit the stock one to match davidm71's for that entire small block area in each instance, except with your data at the specific info locations
1. Extract davidm71's GbE As-Is and then edit, then replace As-Is to your target stock BIOS.
2. From the stock target BIOS, Main padding between volumes in BIOS region, extract As-Is and replace As-Is
3. From the stock target BIOS, FD44 module (aka SMBIOSFlashData / FD44820B-F1AB-41C0-AE4E-0C55556EB9BD) expand to RAW area, select that, extract body, edit, replace body.

Main thing to keep in mind, always replace the same way you extracted. If any header checksums of modules you edit need corrected UEFITool will do that on rebuild

Yes, plutomaniac is a ME FW genius!! And yes, always make backup, and then have someone check it to be sure it's OK and valid if you don't know for sure how to check, before you do any erase or writes

@C:/con/con - Sorry also, for my late reply to you now too
Thanks, yes FD44 will change some things and sometimes not always correct, but I do not believe it will affect what I wanted to check about MAC ID in GbE region
If you want, and you don't mind, please dump GbE region for me (feel free to edit your MAC ID out, but please tell me what you change it to, so I know) >> FPTw.exe -gbe -d gbe.bin
But, if you really want to help, please also dump BIOS region >> FPTw.exe -bios -d biosreg.bin
And tell me your actual MAC ID, for both LAN Ports. This was what I was trying to sort out, where/if second MAC ID goes into BIOS, or not etc (it may be stored in on-chip FW only, we are not sure, still)
@ibsajc has this all sorted out now, but I will like these files/info from you, so I can put into this boards folder, so I know for sure next time we run into this issue.

I have managed to flash SPI chips om the board without desoldering. The best are MSI boards - all successfully. I powered the board, then switched off power and tried to detect chip via clips or SPI cable (there 9-pin SPI port for connecting external BIOS)/ After 2 -5 min the chip is detected and then flashed. The charge of capacitors is enough to ensure flashing by CH341A. Try this method. But Gigabyte boards flashing failed.

i use ch341a pro for the first time, i can't programm my bios w25q64fv with soic8 sop8 test clip. but detect chip and flashing programm no work.
solutions?

@Lost_N_BIOS did you receive the dumps for GbE region and BIOS region from @C:/con/con?
If so, can you give them to me too?
I still have doubts about the changes made by my for ASUS Z170-WS as I wrote in post #624!

[quote=Lost_N_BIOS|p118231]
@Lost_N_BIOS
Have some questions about #1 (GbE region)!
I extracted the two regions from davidm71's dump (extracted-from-dump-GbE.bin) and from the last BIOS found on the ASUS site (extracted-stock-GbE.bin).
Try to compare them:
1. offset 00000000 -> 00000100
- differs more than the primary MAC address
2. offset 00001000 -> 00001100
- missing in "extracted-stock-GbE.bin"
- in "extracted-from-dump-GbE.bin" differs from the first block (offset 00000000)
3. offset 00001400 -> 00001780
- missing in "extracted-stock-GbE.bin"

Hi, can anyone know the pinout of the asrock bios_ph1 pad on the Asrock Thaichi X470 motherboard, a flash on the Winbond 25Q256JWFQ board for flashing with the ch341a programmer, thank you in advance for your help.

Hi everybody, can someone tell me do I need to do same tweaks on ch341a (but with chip CH341B) like on ch341a with black board? You can see pictures attached. I need it for flashing chip with 3,3V. It would be nice to have some feedback from someone who already flashed some uefi chips from winbond series 25Qxxx.

Edit: on Pin 28 is still 5V like on earlier models.
