May I ask how you knew to change the hex value there to put it in manufacturers mode? I've compared to other dell bioses and can't work out any pattern -
You're a genius! Worked straight away, thank you for your help!...Leave a comment:

Would anyone be able to help me with this one please. Dell optiplex 5090 micro, Old service tag was 3FZ9VH3 and I'm trying to change the service tag to 3EZ9VH3 (long story). I changed it in the 2 places I could find, which worked on the older Dells but this one still shows the original service tag.
Thanks everyone!...Leave a comment:

This got moved in here, but isn't really a 7070 specific problem, just happens to be the device I'm facing the issue on. I'm hoping for a way to change the last few IDs on the machine that I think come from the TPM, but so far, BIOS and CPU change have no effect....Leave a comment:

Hi everyone,
I got donated a written off Dell optiplex 7070 mini and I wanted to try setting it up in my home lab with my own personal intune and autopilot (I'm studying for AZ104 and other certs). They are still registered to another organisation though and I cannot get their IT dept to respond to me to have them removed.
Whenever I try and import the device into my own autopilot I get the usual 808- device assigned to other tenant ID.
So far I have tried to change:
CPU
Serial
Hard disk
WiFi card
smbios_uuid
Ethernet MAC...Leave a comment:

Thank you for your replies. I spent a long time over the last few days trying to record what I was doing and take photos to upload and see where I went wrong.
However, I have now done a small acer travelmate and a HP prodesk successfully. No issues at all on these and I managed to unbrick the Dell 7070 as well by using another bios file and resoldering everything super carefully.
So it must be something weird with these silly travelmate spins. Thank you for all your help everyone, much appreciated.Leave a comment:

Thanks for the reply.
I couldn't get the clip on the bios of the optiplex 7070 so that one was done off the board and soldered onto an adapter for the CH341. Even after putting the original bios back on that one and resoldering to the board it no longer boots either

Acer SP-514-54N Bios editing gone wrong
Hi everyone! Hoping to gain some knowledge from this very helpful forum. I'm new to this stuff and I'm obviously missing some important steps.
I have some Acer Spin SP514-54N laptops I wanted to make some changes to the BIOS for.
Using a CH341 USB Bios tool I read the bios successfully. Downloaded a backup copy. Copied that and opened it in a hex editor (HxD). I changed the windows key in the bios after following the guide to find the hex marker. Changed the 25 digits and then compared to the original bios file, and made sure that was the only differences.

Hi everyone! Just joined from the land of Oz.
Wish I found this forum earlier! I have some experience with replacing/soldering BIOS chips and I've been playing with a CH341 (also recently picked up an SPI-25xx tool to try and flash 32 pin voodoo 3 bios chips). But I have no experience with editing bios files or flashing from virgin bios files etc. I have a lot of reading to do!...Leave a comment:
