This also happened to me. I was stuck in diags and I couldn't exit and didn't have ssh or to so I copied geekmasters data.tar.gz

and his sample runme to the userstore
after 2 reboots to se if the runme worked(one to install the data and one to run the runme), I removed the runme.done and replaced the contents of the runme with "idme -d --bootmode main; reboot"
