I hope the issue does not resurface.
There is a custom VIM2 ROM from developer superceleron, you may find it has advantages over the stock firmware. Read about it here if interested.
Also, Krescue can be used to make an entire backup of the VIM2’s current firmware, apps and user data. In the event you did not like the custom ROM, the Krescue backup can be used to restore the VIM2 to your current setup.
