Several times I tried to upgrade from v 1.21 to 1.25 concerning your video manual procedure.
First, the flashing looks very well but after a short time ( between 2 up to 32 % loading) following message appears: Error, download failed. Pls check power and USB cable.
I have changed the cable and connect the power supply additionally but the result was the same.
Please note: during flashing procedure the copy button has been pressed all the time.
What can I do, what is wrong.
For you help many thanks in advance.
please check that the unit can be connected to PC.

Thank you for your answering.
I repeat it once more with same components and same procedure. After ten times - it was successfully. Why that?? I do mot understand it.

That's very strange.
I'm a proud owner of ND-2300, 2500, 2700 and now, 2730.
NextoDi's firmware updating procedure is the most easiest thing to do.
IMO, your internal HDD got something wrong or corrupt files or structures though I'm not 100% sure, Good luck!
