2.Follow the prompts to update the system.
3.After the system update is complete, you may need to refresh your browser.

FYI: updates installed one by one 694 -> 770 -> 783
All volumes (and pool) were lost after 783 was loaded, system asked me to create new ones. I rejected this and manually rebooted system again. All volumes returned back, data is ok. Perhaps it will be a big problem if somebody will agreed with system proposal and creates new volumes (and new pool) at first load on version 783.

Upon receiving your feedback, our lab promptly conducted a retest to replicate the issue. Analysis indicates that this phenomenon is likely due to certain disks not being recognized in time during the system update and restart process.

Therefore, we recommend you try the following steps:
1. Check whether the disk tray is securely fastened with screws and ensure the disk is fully locked in place. You can try reseating the disk and then restarting the device.
2. It is advised to enable Debug Mode in the "Support & Help" section of the system before restarting. If the anomaly occurs again after restarting, further analysis can be performed using the debug logs.

If the issue persists, please feel free to contact us, and we will assist you as soon as possible.

I got the same probleme/fix in 770.

Hello is this release properly beta and alpha tested? This topic is the GA release, right?

GA release.

F8 SSD updated fine, coming from 6.0.770.

Phew, every new update is a risky venture.
There are always brave people (thanks) who dare to share their experiences.
I think I won't update until I've verified that everything works properly and there's no risk of data loss.

Just updated an F2-423 running 770, with an attached D4-320, with no issue. All volumes intact at reboot.

F5-221 updated fine, from -770 to -783, volumes are OK after update.
