Hi,
I've just installed LM19 and after one of its updates It just freezes right after the login, actually the only thing 'alive' is the mouse movements.
I think it might be related to the latest kernel release but I'm not sure.
Never the less, I decided to give a go at the new snapshot feature and took a system snapshot right before the update. However, because I can't get through the login feature, at least the graphical one, I can't get to the snapshot app.
Can anyone help me? Is there a way of restoring that snapshot through the command line?
Thanks in advance.

Of course it can be done from CLI, but will be fiddly - and varies depending on what type of snapshot you created (rsync, btrfs or LVM). Simplest to use a liveCD - your install USB for Mint should do.
Trivial search returned this as second hit - seems to cover things well.
