DSO Quad Bootloader corrupted

At the end I succeeded recovering my DSO Quad !

you will be asked for a License number that is calculated starting from your Hardware Serial number. In order to know it you can use the SYS FW 2.50 I modified to show you at startup the License number further to the Serial number.

I have loaded your modified file Sys 250A.hex but do not see my license number upon restarting the DSO Quad. The start screen says that I have Sys version 1.50 and App version 2.50 .

Should I be seeing the license number on the bootup screen? If so, is there a possibility that someone replaced your modified Sys 2.50A with the original file?

Any help appreciated.

I think that it has been replaced for some reason.
In any case you’ll find attached a new one that should work fine.
