Hello,
When upgrading from Recalbox 6.0 to 6.1 on the XU4, I'm getting an issue with a black screen. I updated from the OS originally over wifi and then it black screened so I flashed it. I have tried flashing it twice now and I have verified that it says flash successful in etcher each time. I am using a 16gb emmc chip and I haven't had a problem until the upgrade.
Thanks!
