A: Typically 2-4 minutes for the DS150E, 6-8 minutes for the DS250 (over USB). If it takes longer than 10 minutes without progress, cancel, reboot the PC, and start over.
Once you have a working firmware version (e.g., v3.4.2), use a tool like to read and save the full firmware binary from your device. If a future update fails, you can flash this backup directly to the EEPROM.
When you perform a Delphi Firmware Update, the Delphini (Diagnostic Software) attempts to erase the old firmware and write a new bootloader. If this sequence breaks, the device enters a "limp mode" or becomes completely unrecognizable to Windows.
