maybe the gop ver is 1062, try to flash bios with ver 1059

582

Hello, thank you for this tool! I am having a little problem when flashing to BIOS ver 2202 using USB Flashback on my Z170 Sabertooth S. The computer just hangs there in a powered state with no video indefinitely. I can get the mod to work when using BIOS version 3801, but this isnā€™t really an option since I plan to use a 9900KF.

Steps Taken:
1. apply allinone tool to 2202 BIOS
2. apply the SyncAllCoreRatio patch to modded BIOS
3. use Coffeetime to unlock regions and transfer MAC address & personal data
4. use Coffeetime to place BIOS into .CAP
5. Flash via USB Flashback

Again, these steps work with version 3801, but not 2202. I can also use Coffeetime with 2202 but with mixed success -I get ACPI compiling errors. Below is a copy of the modded Bios ver 2202 that isnā€™t working, if that helps.

You should use SPI programmer.

584

@oldirdey Try place tool in the drive root directory.

585


Try use z370 gaming m5 BIOS.

586



Will give it a try the next days. Is 1062 to new for b0 cpu?



Just copied the files over and the "problem" was fixed.

I finally got a 9900k for my Asus Z270F (with ported Z270F modded bios). Following this pinmod map (https://2ch.hk/hw/arch/2019-06-02/src/35ā€¦38858521071.png), I put some kapton tape on two positions, connect the other two with EE pencil and press the power button. However, the psu fan and GPU fan spin up for a second before shut themselves down. Neither CPU fan nor case fan spin up. I put a G3900 back and everything runs normally.

So what exactly I did wrong here? If anyone can confirm that this symptom is due to the motherboard doesnā€™t recognize my 9900k?
I suspect the EE pencil doesnā€™t really connect the two required pins. So what would be an alternative? Should I order a conductive pen to try it again?

588

@Rez seems like ME version problem.

589

Oh, I didnā€™t think about that at all. Shall I downgrade it to 11.7 or earlier?

Hello, thank you for this tool! Works great. Thanks
I have some problem when flashing to BIOS ver 2202 using SPIprogrammer on my Z170 MAXIMUS VIII HERO(M8H).

cpu 9400F
MB MAXIMUS VIII HERO

Steps: (tool ver 2019.618)
1. apply allinone tool to 2202 BIOS (no error)
2. using SPI programmer flashing the BIOS
3. power on the motherboard debug code show 31, the computer just hangs there

I try using BIOS v2001 v1902 v1701 have the same problem(debug code 31).
But using BIOS v3201 v3401 v3504 , it work great.

I have no idea why canā€™t using under BIOS ver 3xxx.

591

The BIOS before 3101 do not support the Kaby Lake CPU.
That KBL support is a must have for adding the CFL cpu support.

Hello, revlaay
I tried 9100F on Asus H110M-R. The BIOS for I3-8100 worked fine with 8100, but with 9100F and BIOS for 9100F it does not POWER ON! BIOS ver 4205 - the latest. Fan does not start at all! What is the problem? I flashed BIOS using CH3141A. The same problem with Asus Z170-K. I did nothing with CPU, no connecting or isolating . Its code is SRF6N

593

Iā€™ve got 9400f 906ED
Iā€™ve patched the bios for ASUS Z270F! Done the cpu padding correctly but the mobo starts then shut down instantly after a sec or something
What could be the problem

594

Same symptom here with my Z270F. I will try to connect the two pins on my 9900k again and see if it works.

Btw did you mod the z270f bios yourself or use the ported z370 one?
What method did you use to flash the modded bios?

595



i tried both revlaay tool and ur modded bios , same issue , iā€™ve read somewhere that;s new microcode (906ED) for 9400f needs to be added to modded bios
afudos.exe bios.bin /GAN

I am using main b250h strix like that? Can you give me your bios file please? Thank you

597


I am using main b250h strix like that? Can you give me your bios file i3 9100f please? Thank you

598



well i found that SRF6M is u0 with cpuid 906EA which is already there in the microcode list

again i donā€™t know why this shutdown is happening @revlaay , please help :slight_smile:

599

Tried the silver ink to short those two pins, downgrade my Intel MEI to 11.7.0.1057 but still no dice. The system shutdown immediate after pressing power button.
Any suggestion? @revlaay @svarmod

I am trying to get 9900k to work with Asus Z270F, so far the modded bios seems to work with g3900 I used to get it booted.

p.s. using Z370F port bios version 2001

Use SPI programmer to flash bios.
