Good afternoon, Working on getting 7.1-DS3622xs+ working on my Dell T20 that I've had offline for quite some time. I'm able to get the box booted with redpill up to the point of installing the pat, but I receive the error: Failed to install DSM. Failed to install the file. The file is probably corrupted. Anyone have some troubleshooting tips that I can check on?
