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.

Hi @val, We still haven’t gotten your answer, we wonder if this problem is resolved.
Please feel free to contact our service team for warranty service.

Hi @BLUETTI_CARE ,
thanks for your help guys. Unfortunately, it didn’t solve my problem. I was able to registered it to my name, but according to app info, it’s up to date, most recent software already installed. ARM 2057.11 DSP 2056.10
What should i do?
Thanks

Hi @val, Can you tell us is there any error code on the EB3A?
You can long press the AC and LED power buttons simultaneously when overload, then you can find the specific error code.
We have already applied to push a new firmware for you.
Our IT department will push the latest version of firmware to your machine in 1 working day. Please upgrade it tomorrow.
Please do not load any device when upgrading it.
Please let us know if it works.

Hi @BLUETTI_CARE
error is 2-10

Hi @BLUETTI_CARE
I did the both updates and it doesn’t help. Still the same error.
And now it’s draw 4 watts with no any connections for a 3-4 seconds and then dropped to error 2-10

Hi @val, Thank you for getting back to us so quickly.
If the error occurs even with no load connected, it seems that the unit may require repair.
Could you please let us know your location, and we will look up the appropriate service email address to assist with the repair?
