BLUETTI EB3A DC SHORT error

Hi all.
I bought a BLUETTI EB3A from a local pawn shop. The AC inverter works fine, but in DC mode it shows a DC short error. Someone on youtube fixed the problem with the firmware update sent by Bluetty support. My unit is registered with the previous owner’s email, so I can’t get any updates. Is there a way to unregister my device and register it in my name?

Hi @val, we would like to help you.
Please contact us via message, and provide the EB3A’s SN code, then we will disconnect with the original account, and then upgrade the firmware.

Hi @val, Thank you for getting back to us so quickly.
Now we have disconnected the EB3A from the original account.
You can register and log into your own account now.
