my sister switch in 10.0.4 with SD enabled can't boot on the CFW it gives me a black screen right away... ( with a réal sandisk SD 64Go )

SO i tried with my switch in 10.0.4 (which did not have the update of SD card) but I can not do it without upgrading to 10.1.0
If I try to generate a license with my SX pro it gives me the invalidity error message for this console. if i continue i have a black screen...

I tried with several versions of sx os but nothing works... what can I do ?
both times I had to create the license online.
