Dell 8FC8 Patcher

[Stefan Steff]

Hi,
I have a question about the tool, not sure if it worked or not. I ran my bios dump in the tool and got this result:

BADCAPS **Dell-8FC8-Patcher**
rex98 **Bisayang Dako**

Checking for 8FC8 Hex Pattern...in file C:\Users\reneg\Downloads\dell_bios_dump_1.bin

8FC8 Hex Pattern Found at offset 0x10

Checking for first 8FC8 Hex pattern...

8FC8 Hex Pattern Found at Offset F41B1 and Replaced.

Checking for Second 8FC8 Hex Pattern...


File not Unlocked...8FC8 Hex Pattern not Found


Press any key to exit...

And assumed it didn't work, so I posted in the bios unlock help thread for the experts to take a look but I just noticed that a new bios file has appeared in the original folder with 'Unlocked' as a prefix.
Does that mean it worked? Or did the task fail successfully?

I'm tempted to try the unlocked file, but I also don't want to have to remove the chip again, any guidance you can give me would be much appreciated.

First of all, post your machine type and model, service tag and your original bios dump .
Then someone will patch it for you and after that you can compare the two patched dumps to see if yours it's OK or not.

Sorry about that. I keep forgetting to add all the machine details. As it turns out, the bios file was corrupt and unusable.
Thank you for your help.

It's the same method, read your bios chip and use 8FC8 Patcher

Thank you! Its work!

How to open a 32MB BIOS? Do I have to change the HXD number? Please guide me.

Hello!
I am unable to clean the 8FC8 BIOS using the Patcher.
DELL AIO 7480
S/N 3NSF8B3
DELL Optiplex 7480 AIO Motherboard IPCML-GZ/UMA M-ATX 05T2V2 5T2V2

Could you please advise how to proceed or if a different method or tool is required?
Thank you

[Sparo]

That’s normal. You can’t clear it because you have a bad dump. Read the chip again

[Lenin31]

Thank you, Sparo.
Unfortunately, it’s not possible — I made a mistake and already cleaned the chip.
Have a nice day.

[Sparo]

What system number is displayed after you press Unlock?
That's if your machine still turns on of course

[Lenin31]

Sorry, I cannot find this information at the moment, but I believe it was 3NSF8B3-8FC8.

[Sparo]

I sent you a new BIOS build file below. If it doesn’t work try some dumps from here > https://www.badcaps.net/forum/troubl...d-removal-help

Thank you, Sparo!
Your BIN file works great! Thank you for your time and help.
Have a nice day

So how does one do this for a Dell Optiplex 7010 Plus SFF? I bought from an excess sale from a company. Popped a new SSD in but i cant boot to my imaging USB to install my OS. BIOS has 8FC8 but I nor the company have the password for it.

Hi and Welcome to the Forum! All is detailed here > RULES UPDATE for BIOS requests/offers *AVOID BANNING, READ BEFORE POSTING* - Badcaps
Basically just post the service tag and a GOOD backup of your BIOS chip to unlock > BIOS guides, methods, resources and tools - Badcaps

hi, it sounds like you need basic help on how to re-program the BIOS on a PC/laptop ? I was in your position 6 months ago when I bought several -8FC8 locked Dell Latitude laptops on eBay, so here's my experience/advice :
You need to buy a chip programmer device, which you use to read the BIOS contents off your locked PC and store it as a file on your laptop. You can then edit the BIOS file (e.g. using the 8FC8 patcher program from this forum) , and then you use the programmer a second time to write the unlocked BIOS file back to your locked PC.

I bought a T48 programmer off eBay, along with two clips which allow you to physically connect to the two most common sizes of surface-mounted BIOS chip ( WSON8 & SOIC8 ). You'll need to locate the BIOS chip on the Optiplex motherboard to see what size/type of chip it is.
Most forums recommend unsoldering the BIOS chip from the motherboard before reading its contents, but this needs specialist soldering equipment & skills, which I do not have; and I have found on many Dell Latitude laptops the T48 is able to read and write the chips 'in-circuit' , i.e without unsoldering. You just have to remove the motherboard from the laptop/PC, disconnecting the battery AND all peripherals. Again , not sure if this will work on Optiplexes, but I have a couple of Optiplex 9040 micro PCs here, so I may check this weekend if I have time.

YouTube has videos which show how to use the XGecu software which you'll need to load onto your laptop to operate the T48 programmer :

good luck!

P.S. if all the above sounds like a bit much hassle, and you just want to be able to boot your locked PC from its SSD and get on with your life, you have the option of using another PC to install the OS onto that SSD , then physically move the SSD into the Optiplex. If you're using Windows I'm always slightly surprised how well Windows 10 & 11 reconfigure themselves onto different hardware when moving SSDs between laptops/PCs like this.
Of course this method leaves the BIOS locked, so you'll never be able to change BIOS settings, nor ever boot from USB etc. But if you're lucky and the BIOS is already set for UEFI boot, Secure Boot on, etc , then this may save a lot of faffing around with programmers etc ..

Hi and Welcome to the Forum!
Sure if you can't do it yourself then post your BIOS backup

[sql98]

Bios version is 1.6.5
service tag is G6WSM13-8FC8

I don't think you understand what the 8FC8 patcher does. You need to use an external programmer to back up your BIOS chip
ONLY then post the resulting backup file to have it unlocked, this can't be done by only posting the Service Tag
So get a programmer and read your BIOS chip, Click here > I don't know what is a Programmer
