Wonder between this loxjie and the cheap SMSL SU 1, which sound better.
i have already update the fireware,don't mind the description,plugged the usb port is ok.first power off,then Press and hold the knob, then turn on the power, and release the knob after 5 seconds. D40PRO will start and screen will not light up,You can continue following the documentationHas anyone successfully upgraded this firmware?
I found the badly-translated instructions confusing.
1）Don't supply power to D40pro first ... "
"6 ) Connect the D40pro service interface to the computer via micro USB cable(NOT the USB
input interface). Press and hold the knob, then turn on the power, and release the knob after 5
seconds. If you see the D40pro starts normally, you need to repeat this operation (when entering the
upgrade mode, D40PRO screen will not light up). ... "
There is only one USB port on my unit (and it is currently connected to a PC). The power cable is plugged into a power strip, which is plugged into a wall socket. What do I do? Unplug it from the wall, then run the upate and plug it back in? (My best guess).
Sorry to say that I was never able to update mine. I followed ivanyi's instructions to the letter, but no luck. It always fails at the point where the installer is supposed to connect to the device. When I press the connect button (or select "Connect" from the menu) nothing happens. If I press the Start Program button, I just get a message saying "Disconnected". I'm giving up on this until the commany gets its act together. And I'm changing my rating of this product from 3 to 2, for its poor documentation and update and its virtually non-existant tech support (I have literally never received a response to any question regarding the D40 or the D30).
Tried again. Since my computer is under my desk and my D-40 is on top of a cabinet, under a TV, I had to run a USB extension cable to reach it. Since the extension cable is USB 3.0, I purchased a USB 2.0 extension cable and tried that as well. No luck. Same result as always. It was never able to connect.
I have to say that I'm not convinced that using a USB 3.0 port or cable would make a difference, since they are supposed to be backwardly compatible to the older standards. And though I would expect there could be an issue if I was trying to use a USB 2.0 cable or device on one that required USB 3.0, I have never seen a case where the reverse was true.
I think this is just shoddy tech support, upgrade, and documentation from Loxjie and I will have to take that into account before I purchase any of their other products.
