@ALviK98 - For W25Q128FV - only Colibri (included below) or ASProgrammer 1.41 has been confirmed working here by others for both read and write
https://ufile.io/p21lj9ck

1.18 will give valid read (at least the 1.18 in package above, can't comment on others), but it will fail write
Best to use Colibri or ASProgrammer and make a new dump, that way you know it's a good dump and you know you will have good write with those too.

@Rez - Yes, I've seen discussion about those backports and RGB, there is fix for that, but sounds like you are already using fixed BIOS now.
You need to downgrade ME FW manually, using the guide, not using CoffeeTime, and then properly insert microcode (make sure no padding above/below microcode is added or removed + fix FIT once you are done).
You may also need to downgrade vBIOS/GOP. All this sounds like something I would not waste time on in your situation, because it's temp and you don't plan to use for long, I'd pass and just wait it out.

@markoz - Probably bad mod, double check BIOS vs stock, you may need to edit something differently for other BIOS

@Poply - MAC ID is on a sticker on the board, either by LAN (on top, bottom, side of LAN Metal block, or plastic in that area), or on side of 24 pin or possibly top/bottom sides of PCI/PCIE slots.
You can also run this command to get, if LAN enabled, make sure it's not Wifi MAC ID you grab >> IPCONFIG /ALL

If you're familiar with FPT, you can also >> FPTw.exe -gbe -d gbe.bin

@adelage - UEFITool does not convert cap/bin/rom etc. So, at #1, hopefully you mean that you have extracted BIOS Body from capsule, and saved as bin/rom (this = same/same)
^^ And due to this, #4 also points directly to my first comment above too (no need to convert bin to rom, it's same, and UEFITool does not convert such, but you can rename with it I guess if you wanted )

BIOS Body must be put back into stock capsule via HEX editor, you cannot simply rename to .cap
See here - [Guide] How to get full NVMe support for all Systems with an AMI UEFI BIOS (394)

But, since you used update method in windows, IF BIOS flashed in, you may avoid above hassles. Often though, this method in windows only "Looks" like it flashes your BIOS, but does nothing.
So I highly suggest you do it properly via USB Flashback, and really, for Coffee mod, this will fail too, unless you do the hardmod for USB Flashback to flash all regions (I don't have any info or links on this, you will have to find).
Programmer is needed without that, because you have to flash in mod ME and FD regions, and that is not done by USB Flashback or other other software method.

So the above is the reason for your issue most likely, but you may also still have pad isolation missing too. That and/or your SKTOCC mod is not correct.

thank you, ho to best check modbios vs stock?. the only difference in mb are that tb250-btc is with 6pci-e, and btc+ and btc pro have 8/13 pci-e slots. I dont know if that has something to do with anything.

Done, Thanks

@Lost_N_BIOS By MAC ID you mean the MAC address? Cause that's what I get with ipconfig...

Hi @reactive , sorry for troubling you.
A couple of days ago i've finally recived my G20CB motherboard.
I mounted and connected evrything to it.
It got shipped to me with 1701 bios version. Right now i only have a i5 7400 cpu on hand. I'm trying to test if this mobo even works but i get no signal.
I've tried flashing even 2202 (latest) bios and still nothing.
I turn it on, fans start spinning then they turn off and restart again. No video signal and anything.
Do you have any idea what it could be?
I mounted a pair of samsung sodimm 2400mhz ram and a m.2 sata ssd.
Could it be ram related or cpu that lacks bios microcode?
Did you encountered anything similar?

@markoz - I meant for you to check stock BIOS vs mod BIOS side by side with UEFITool NE, look at "Parser" tab, all should match before/after, then look at ALL touched volumes inside BIOS region, all should match 100% before/after (no added or removed paddings or other files/modules)
If you are not sure which volumes have been touched, then compare/look at each one, from top to bottom.

@adelage - Great you got it going now Yes, I don't think even with BIOS mod to reveal multi setting that chipset will allow CPU multi change, but I'm not 100% sure, you should try it and see

@Poply - Yes, MAC ID is Ethernet LAN MAC address, you need this to insert into mod BIOS so you can flash it with FPT via full BIOS flash (FPTw.exe -f biosname.bin)
Or you can flash in all regions one by one and skip GbE (ie DO NOT use FPT without a region flag >> -desc, -me, -bios), otherwise you will have to fix GbE region later to fix MAC ID

@ALviK98 - Should 7400 CPU work with BIOS 1701 or 2202?

@Lost_N_BIOS Good question...
I've seen in forums that it should be working with the stock 2202 bios but nothing is happening...
I just don't know if there is any microcode support in the stock bios or how to check it...

@Lost_N_BIOS I have tried with FPTw and FPTw64 (version 11.0.0.1160) but I get the following error:

Error 367: [FPTw.exe] cannot be run on the current platform.
Please contact your vendor.

As for the MAC ID with ipconfig /all:

Description . . . . . . . . . . . : x
Physical Address. . . . . . . . . : x

Do you need any other info?

@Lost_N_BIOS Okey, I've managed to find a suitable bios to boot my G20CB motherboard.
Basically i took the bios of the G20CI (H270) and copied it's "BIOS region" to my own G20CB 2202 bios.
And it booted up, seems to be working fine.
Some issues:
-Fans are bugged in bios but i can control them through "SpeedFan"
-One single temperature reading is wrong (i hope it is) showing me motherboard temp 120C (on AIDA 64)
-Wifi not working at all...


Also, I've started digging into my GR8 II bios.
I dumped it using CH341A clip. I'm thinking about those bio menu unlocks. Do you have any tutorial about them?
If you'r not too busy, could you do it for me? I dont really know how to do it :/
GR8 stock bios: https://drive.google.com/file/d/1o_LYDyY...iew?usp=sharing

@ALviK98 - Tell him don't be scared, he's only "Reading/Backing up" so nothing can go wrong provided he can copy/paste commands safely
Link me to BIOS in question and I will check and tell you what microcodes are in there. OR you can check, drop BIOS on MC Extractor (run exe, drop BIOS on CMD window) and it will show you - https://github.com/platomav/MCExtractor/...ag/v1.48.1-r159

Sounds like a mess doing what you did with other model BIOS region, I would not run like that. I'd wait and get proper BIOS made from your correct BIOS

On GR8 - please make a thread if you need unlocked BIOS menus, then I can help. IN that thread, please link stock BIOS download page (not the BIOS).
Also, since you have programmer, add your dumped BIOS to that thread as well.. What is BIOS chip ID, and what software/version did you dump the BIOS with?

@Poply - What is your ME FW? If you have V11, then that is correct package, you may just need to run as Admin and are currently not?
Here is registry fix to add "open CMD as Admin here" to right click, add this to registry, reboot, and then in the folder with FPTw.exe right click and choose open CMD as admin here, then run command
https://ufile.io/aprsmcyi

But, this only needed for you to have backup. Since you know your MAC ID, we can make you a BIOS now. Please reply with ALL info in same reply again so it's all in one place, then I can make you BIOS.
At reply, link to BIOS download page and tell me what BIOS version. Tell me your old/current CPU model, and your new CPU SSPEC (Printed on CPU). And then MAC ID again.

Hi @Lost_N_BIOS Okey, I've made a new thread regarding GR8, check it out when you have some time :)
ASUS GR8 II Bios Modding

About my G20CB adventures:
Yeh, i know that it's a mess, but i needed to test the motherboard if it was even working, and since i had only a i5 7400cpu had no other choice.
Still, for now i'm focussing on the GR8 project since i've managed to test the G20CB motherboard.
In the future i may actually plan to mod it too. But from what i've seen, the original bios just doesnt want any other microcode other than it's own. (I've tried using automated Coffelake tools to add support for coffeelake and 7th gen cpus but it still didnt work).
Anyways, this is the end result of my hard work (lol).
Basically bios region of the G20CI motherboard copy/pasted to my stock G20CB bios. And it worked (with tons of bugs tho)...

@lkadlcek - Yes, the one in between M2 screw hole and TPU chip.
This is Micron 25Q128A and it's 13 on 2nd line so 3.3V chip - However, this chip may be an issue, unless it was just issue with specific situation/board for
@kazp3r here page 73-76 [TOOL] Easy automated Mod tool for Coffee Lake bios (76)
kazp3r - whatever happened there, looks like you gave up, or did we carry on in PM's etc?

I've seen others read and write to this chip, so not sure what the issue was in his case, but it's last one I helped with on that same chip ID
But, if you can't get it working with clip, then we can program directly through the SPI header on the board, but you'll have to make some cables to do that.

@ALviK98 :
As I remember I replaced the BIOS region too. After that I replaced some modules in the new BIOS region with the old versions to get fans, voltages and temperatures working properly (Nuvoton NCTxyz, SIO related, BIOS must know, what SIO chip is on-board and what register contains the values expected).

For WiFi I modified some PCI express related things in a tool from Intel.

It's too long ago, I don't remember everything, and I lost everything because an accidently delete :( .

Well, rip :(
