@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.
