Thanks everyone,I ran into this same issue.

To fix I placed a dummy sim card that came with a pack of sim card adapters into the m.2 to pcie sim slot and this keeps it from shorting out. Works great now.

It took that time. I downloaded a fresh file"routeros-7.1beta3-arm64.npk" dragged to File List and rebooted.

previously i had used all the files from "all_packages-arm64-7.1beta3.zip" and it never worked.

Thanks for the help.

You can't auto-upgrade to v7. You must do it manually as using any kind of BETA is not recommended.

It shows arm64 in the current stable release file.

Meant the manual upgrade from within WinBox? Within the update section it shows error cannot find file arm64-7.1beta3.... something like that.

Looking to update my LHGG lte kit with ROS7. The device can't auto find/download the file. And the arm file i see won't work manually either.

Any help, is there a beta7.0 file any where?
