Hi @Fernando,
I followed your instructions and use Flashrom utilities try to dump BIOS but fail. I attached the screenshot:

My Computer model : Lenovo M73 Machine Type and Model 10B7S04100
BIOS version : FCKT98AUS
Here is my pc spec: https://pcsupport.lenovo.com/us/en/produ...015acu/warranty

Please help .
Thx

Having this error following annex guide on Asus X570 Tuf plus wifi after most recent bios update.

A HUGE Thank You goes to Oldguy on post #588 for these instructions. I had been racking my brain for 10 hours trying to get an Asus Maximus VI Hero (with the z87 Chipset) to accept and boot from an NVME adapted Sabrent SSD card. Your method with AfuWinx64 and flashing the ROM twice (once with the original, and second with the modded NVME loaded file) within Windows 10 x64 worked! It seemed so silly simple; why didn't Asus just do this and release an update is beyond me. But you saved the day, this computer from being chucked out a 4 story window, and my sanity. Thank You!

@t0ph3r Same here. Have you found a solution?

I flashed 3405 thinking I could downgrade if necessary, since the flashrom method has always worked for me. Unfortunately, 3405 caused my PC to lock up completely for the first time.

1. Bios renamer has been removed from Asus's site for board above.
2. I have read all the techniques to flash and get security error using bios tool, direct flash stalls with solid green light and does not finish.
3.I have use original name from Hancor, just 2103.CAP and Z87-PRO-AUSU-2103.CAP same results.
4. Sandisk 16gb drive empty Fat32 USB 3.0.
5 Have not tried a USB 2.0 drive.
6. I need the NVME booting support.
Am I using the wrong names, I am at 2005 flashed from bios screen through the tool. I can probably get 2103 unmodded on but that will not give me NVME boot support.
If I have to go to one of the other two more drastic options I want to make sure I use the proper tool for this board could anyone help out? Obviously, this board will not let me get past its security verification check
BTW the Current Bios updater tool will not run with the Intel MEI version installed by Win 10 20h2 as it says the driver is not installed but the device manager clearly says it has Intel MEI 11/03/2017 version 11.7.0.1045. So
it must check for the original version to function or not recognize 11.7.0.1045.

Well if u looked a little further and taking in consideration that a mod is not an official file, its an expected situation dont u think so?
No one is offering u bypass for OEM security issues for any brand manufacturer...

Im sure that u can spend a little of ur time and maybe learn something if u want: [Guide] How to flash a modded AMI UEFI BIOS

Ill give u a hint on ur motherboard feature... https://www.asus.com/microsite/2014/MB/N..._compatibility/

That behaviour is entirely expected, evidently you have not read this page; paying particular attention to ASUS motherboards:


Guide for ASUS mainboards with an AMI UEFI BIOS


[Guide] How to flash a modded AMI UEFI BIOS

I did read Fernando's page before I posted.
I used this option: A. Using the ASUS "USB Flashback" procedure (easiest option) Light blinks then turns solid and stalls!! Does not update. Further using bios 2005 using the motherboard button flashback to update (green led light flashes and then stalled staying lit up) had to do this update from Bios screen using built-in bios tool. Bios was on 1604 when I started. Now on 2005. I have flashed a modded NVME bios before on another board from Asus and It worked fine.
Using the ASUS AI Suite
I did not use this option. In addition, I read it before I posted.
Using the Flashrom tool: (recommended for 32MB sized BIOSes of AMD chipset mainboards) This is not a 32mb bios and it is not AMD and I did read this before I posted!
I read this below and The Proper AMI tool, for this board, was the question I asked:
The Company AMI itself offers >here< for their different BIOS platforms (AMIBIOS, Aptio IV and Aptio V) specific BIOS Update Utilities. They are as well available within my OneDrive account (look >here<).
Another tool, which is able to flash a modded BIOS into the BIOS chip of Intel Chipset mainboards is the "Flash Programming Tool (FPT)", which is part of the related Intel (CS)ME System Tools version. You can find the specific Intel CSME System Tools for your mainboard within the chapter C2 of >this< start post.
My feeling is I am going to get this anyway: (FPT)" gives an error message due to the MODDED BIOS's WRITE protection; Our BIOS Gurus SoniX and Lost_N_BIOS have written guides about how to solve this problem by using different methods. These guides can be found >here< (SoniX's Guide) and >here< (Lost_N_BIOS's Guide).

And I will end up giving up.

@dasboot

Well then you're giving up too easy...I suggest to try a number of different USB sticks, Sandisk brand has worked for me in a variety of settings. There is some trial and error to finding the correct one. For instance on my Z87-Deluxe board I need to use the Sandisk USB 3.0 type (8 to 32GBmax); while on my more modern Asus ROG Zenith Extreme I need to use a USB 2.0 type at 32GB size. Just because it didn't work on the first go around, may mean you just need to find the correct combination.

Why not try the vanilla bios version 2103 from Asus; which should be a cakewalk and it's already validated for the board.


https://www.asus.com/us/supportonly/Z87-.../HelpDesk_BIOS/

Look for version 2103 and download it. Right click the file and rename to Z87P.CAP

Get out your favourite USB drive and mount in the correct flashback slot as shown in your manual on page 2-11, 2-12.
If you took the time to read the relevant pages it states right in your manual:

We recommend you to use USB 2.0 storage device to save the latest bios version for better compatibility and stability.

Thus the lesson is more reading and less carping to the people who are offering you HELP...

This proves you didn't read your own manual...which in the military would get you a good barking to RTFM.

We like intelligent questions not LAZY questions.

You can do better, now go do it.

As I said I used a Sandisk Cruzer Force 16GB which was 3.0 on my first go around. I ordered a Sandisk USB 2.0 drive which 8 GB from Amazon. I will try again.
No point in going to 2103 from Asus yet as it does not have NVME booting support. This is not my machine although I built it some years ago for the current owner.
I am just upgrading it for the original owner. I also have an identical machine I built for someone else and I was going to suggest this upgrade for him too as the NVMe drives are so much faster than the SATA SSD currently installed in both of these machines which are Samsung Evos. Personally, I would just move on to a newer chipset board as all the busses are much faster and the processors are more efficient, and on smaller dies. I just built a 5600X with a PCIE 4.0 NVME drive with a Mini ITX Asus Stix X570 for the owner of the rig above I am doing the bios update mod on so he does not really need it back right away until I am finished. I can just l return it with 2103 not modded and a SATA SSD and he will probably hand it off to a family member and everyone will be happy not knowing any better, but having the extra speed of NVMe would be a plus.
I am well aware of the USB 2.0 ports being a better option even for loading an OS especially when building a Hackintosh as the OS will not load on certain newer intel board and since newer boards do not have USB 2.0 ports only internally in some cases an internal USB Molex to USB A adapter to flash drive has to be used to get this problem solved.

Old Sandisk 512 mb flash for doing old school machines did the trick bios flashed to microcode 28 mod flawlessly. Slower is better... I think this Old REEUR8 drive is USB 1.0 so this may have been the pot of gold.
You will never find a drive like this now, lucky to even find an 8GB drive, that is not throwaway crap. USB 2.0 drives are hard to find in name brands. I have hundreds of 3.0 and 3.1 drives all-metal cases all name brand as I will not use crap but in this instance the older the better... Like me. Thanks to Hancor and Fernando and, I can read....

BTW it was USB 2.0 but barely. https://www.amazon.com/dp/B000F2WMXQ/?tag=computertohome-20 but maybe only Ebay as a source now...

@dasboot

BTW for others, you can also find USB 2.0 here:

Well Alleluia!! a kick in the pants @dasboot results in digital SUCCESS.

Amazing what you can accomplish by diligently following the DESTRUCTIONS...!
