my modduo does not boot anymore. I had an error trough the web interface while making pedalboards, and since the moduuo is stuck on boot screen.
I followed the troubleshooting page, but any attempt to reinstall bootloader or make a factory reset fails with the error :
ERROR: Allwinner USB FEL device not found
I am supposed to play live with my modduo saturday, still no answer today, I understand now that it’s hopeless. I will get by with integrated effects of my amp… it sucks.
What should I do now ? send back my mod to customer service ?
yes I am using debian. I can also bring my mod at work to try with windows 10 if it helps.
Yes I kept the button pressed during power up and for a few seconds.
And I am based in France. But I am OK to follow instructions to try to fix it before shipping it back (I am working in electronics, and I designed an embedded linux device some years ago… I am not afraid by command line, or by opening the case if a cable needs to be connected directly on PCB).
still stuck. bootfix still giving “ERROR: Allwinner USB FEL device not found”.
I checked the USB cable and USB port of my PC with another device, it is functional.
I tried with the other USB port of the moddevice (port A), just in case, as the troubleshooting page just states “connect via USB” without detailing which port.
So what can I do ? Should I ship back the modduo ? I would prefer trying to fix it if possible with standard equipment.
Recently my Mod Duo has been acting weird. It used to be that it needed a few attempts to connect to the browser, to later on starting up but not loading any patches (and not being able to open the banks). Right now it doesn’t start up at all, it just shows this on the displays. I’ve tried to reboot it, tried holding down the left knob+left footwitch while starting up, tried pushing in the FEL-button while starting up - Nothing happens…
the “hold down the left knob and the left footswitch together” advice was missing the essential part of doing that during boot.
for that I mean, do that while powering on the unit, and keep holding for 5 seconds.
the unit should enter “recovery mode” where you can install the latest release image.
can you confirm if that works for you?
Yes, I tried that. I tried holding them down while powering on the unit. No response at all, no lights turning on, nothing. The displays just shows the logo on the left display and the “Mod Duo” on the right display. I also tried holding them down after powering on, nothing.
I tried holding the FEL-button while powering on, nothing happens. I’ve tried to push every pushable knob/footswitch in every possible order, nothing happens. It just stays on with the displays not changing until I unplug it…
I don’t know what to do, can I ship it to someone to fix it for me?
As I said, I’ve tried that too. I’ve held down the FEL-button while powering up, noting happens. I’ve had the Mod Duo connected to the computer via USB, but the computer doesn’t find it. I’ve tried having it plugged in to the computer while powering up, I’ve tried holding the FEL-button while powering up, then connecting the USB. Still nothing. The device is on, but the displays only shows what I said in previous post.
I can’t even do a factory reset, since I can’t get the Mod Duo to connect to the computer.
I have tried every single thing written in the troubleshooting page. I did all of that before consulting to this forum.
I really enjoyed using the Mod Duo so I really want to get it fixed…
My unit got delivered about a week ago, but haven’t heard anything. I get no response on the emails and just want to check the status of the repair, or at least get a confirmation that the package was received
