That's a bug in the software. Could you PM me the firmware so I can debug?Originally posted by PITERPENY View PostComment

[QUOTE=MuertoGB;n3510142]Hi can i remove EFI lock of this a1993 with your program?, or do you have idea how to remove?Originally posted by Kien Pham View PostComment

I've made a temporary patch for this as I've got to release 2.0.4. I'd still be happy to take the firmware for debugging when if you can. The application will now accept Apple Silicon SoC firmware; however for now you cannot do much with it.Originally posted by MuertoGB View PostComment

This beautiful tool is observed that it can help us remove the EFI password from the system to perform a new installation. Is this section of the EFI password removal tried without the computer dying (so it won't boot), and is it possible to install a new system?Comment

Sorry, I don't quite understand the question amigo. Please try and be more specific.Originally posted by aldodavilam View PostComment

Hi,
I've bought a MacMini 2018 listed on eBay for parts.
Blinking STOP sign upon startup.
Read the SocROM with XGecu T48 but Mac Efi Toolkit is not able to find Serial Number.
Searching on EveryMac for ORDER NQ2Y2LL/A gave no result.
Any suggestions to find serial number?
No key combination uppon startup gives any result, only was possible to start in DFU mode and revive/restore.
Then machine reboots and goes to blinking STOP.
ThanksAttached FilesComment

Fact the system boots makes it highly unlikely to be anything related to the T2 subsystem. Also, a missing serial number in the SoC ROM isn't unusual. Not every SCfg store contains the system serial.
Via email you told me you restored it in DFU mode, and it has gone back to a no entry symbol, so I'd blame something on the Intel side. Is the board number 820-00939? Have you tried different memory?Comment

Board number is 639-06007
Measured power rails to PCH and so far 1V, 1V8 and 3V3 seems to be Ok.
If there were a way to sniff the boot messages by usb or other means would be very useful.
I suspect either PCH is malfunction (as thermal images suggest) or some peripheral connected to it.
I'm using a memory stick which is working well in another mac mini 2018.
I'll try check power rails of Thunderbolt Controllers tomorrow and PCH clock signals.
Do you have a board layout of mac mini 2028 with traces and pads labeling similar to ZXW type?
I've got one, pdf, just board layout and components name and position, but no traces/net.Attached FilesComment

Board numbers start with "820-", your board is an 820-00939. Check post attachments for BV and schematic (you'll need FlexBV to view). The PCH corner hotspot is a little suspicious I must admit, but I've never observed the thermal behaviour of another one.
If you cannot solve this one, I'd be interested in purchasing it. Could you upload the thermal images here?Comment

Many thanks for the 820-00939 board layout.
> The PCH corner hotspot is a little suspicious I must admit, but I've never observed the thermal behaviour of another one.
Agree ...
Here goes the thermal videos:

> Could you upload the thermal images here?
Yes, please find them attached. One is from another MacMini8,1 which runs well.
> If you cannot solve this one, I'd be interested in purchasing it.
Let's be positive because I need machine to work. 🙂Attached FilesComment

I've issued a hotfix for Mac EFI Toolkit that disables multiple firmware windows being open concurrently. A permanent fix is being developed.

Mac EFI Toolkit 2.1.2 released. Hotfix from 2.1.1 perma-patched with a new parsing architecture. Improved the UI, update window, and other QOL changes. Enjoy.
