Hi,
Is there a way to snapshot the current state before upgrading the SDK?
I want to try the SDK v1.4 but in case of problems need to revert back to the current state.

Thanks in advance,
Maarten

@Kessie Not exactly, but the important data to retain lives in `/data/` or `/data/modalai`

The SDK flash will attempt to retain this partition, but in certain cases it requires a wipe.

I would take note of `/data/modalai/sku.txt`

as well as pull off any calibration files in `/data/modalai`, you can see if you have any onboard currently by running `voxl-check-calibration`

If you have this data saved you'll have no issue getting back to your previous state, I can help guide you through it if you run into any issues.
