Common Q&A
Q1: Is there any risk in updating the Recovery firmware?
A: No risk is involved. The Recovery firmware is separate from the BootLoader and is solely used for restoring the local VNA firmware. The update process will not affect either the BootLoader or the main VNA firmware.
Q2: After updating the Recovery firmware, do I need to update the VNA firmware as well?
A: No. As explained above, the Recovery firmware update is independent and does not require any changes to the VNA firmware.
Q3: The update failed with an error message (see image below). What could be the cause?
A: Possible causes and solutions:
1. Driver installation issue
2. Device connection problem
3. Device not in Recovery mode
