Just tried to upgrade it to the Euro 3.0.22 build 170621 (via the maintenance page) and it said rebooting, after 5min or so it beeped twice - the screen said rebooting still, left it and had lunch for 20min, still rebooting, hit refresh and nothing, powered the NVR off and then on again and now it can't be seen in SADP over my home network.
So I plugged a monitor directly into the NVR turned it ON, get the 2 beeps, and after about a minute a “hikvision embedded NVR” splash screen appears for about 30 sec then black screen again and nothing. I had a mouse plugged in as well, it did not respond to any clicks or movements.
Another user via private messages has suggested the following
Will have to try and get it to communicate via TFTP.
Any other suggestions?

If it beeps twice it means that the UBoot partition is loaded (therefore not bricked) and it tries to load the actual firmware. Since the firmware does not complete the loading, it means that either the firmware has not been stored properly (or complete) or it has been corrupted.
I suggest the following:
1. Try to upgrade again with the same 3.0.22 firmware. It it fails gain do it several times. It finally fails, then step 2.
2. Try upgrading the NVR with the most updated firmware backwards. EU version 3.0.15, then 3.0.13 and so on.
In the past it has been reported that this NVR does not have sufficient BIOS memory for the some versions from some regions (EU, US).
The NVR is completely bricked if it does not respond at all to the TFTP server in your PC during the upgrade process.
Will have to try and get it to communicate via TFTP.
Any other suggestions?
