Thank you very much for updating the thread, and we are glad to hear that your F4-423 is back online and accessible.
From what you described, it is very likely that certain post-update background tasks or processes were running under sustained high load, heavily squeezing system resources and causing core system services to become temporarily unresponsive.
To help our engineering team pinpoint exactly which processes led to this resource contention and optimize future updates to prevent similar issues, Could you send us a system report for analysis?
Thank you again for your feedback and cooperation in helping us continuously improve TOS!
