Q: Can I update the ZR08JP via the Zosi Smart app?
A: No. Major firmware updates require a USB drive and local monitor.
Q: Will updating erase my recorded videos?
A: No. The hard drive data remains intact, but settings (network, motion zones) may reset.
Q: My ZR08JP is stuck at “System initializing” after update.
A: Power cycle (unplug 30 sec). If still stuck, you need recovery firmware – contact Zosi support.
Q: Can I downgrade to an older version?
A: Not recommended. Newer versions disable rollback to prevent security risks.
