I must have assumed it was 2.0 because it was requested for modding. I just re-checked and you're right it does have SLIC 2.1 in the Original BIOS.
Attached is the dump that I've got using SLIC Dump Tool 2.1. It appears that SLIC is present, but Windows report "30 days to activate. Product ID 00426-OEM-8992662-00497". Any suggestions?
Please disregard my last message. I read some more and figured out what to do. Thank you for looking into that and pointing me to the right directions.
Hallo, perhaps this is the mistake I made. I only flashed the rom without the switches and got a message window something like that: "blabla slmgr -Rc C:\msi.xrm-ms slui.exe 0x2a0xBBA " I use slui.exe.... and got a message to install a new key. I'll try it with switches and post the results.
