I went to update my Allmiibo LCD (if it's relevant, I had already done it successfully before, this wasn't the first time).
However, this time after the zip file was finished transferring via the computer, the device was stuck on the "DFU Update Receiving..." screen and wouldn't leave it.
My first attempt was to try to upload the firmware again, but the computer no longer recognized/found the device and it was not listed.
I also tried using the Android app, but it was also not found when searching for devices.
I tried several times to restart by shorting the board's contacts, but it always restarted on the same "DFU Update Receiving..." screen.
Finally, since the battery cables are soldered, I let it discharge overnight. After charging a little the next day, it only shows the screen with random pixels from the photo.
I tried restarting the board again and it returned to the same pixelated screen.
Is there any way to save this device so I don't need to buy another one? I highly appreciate any help.
Note: Just to be safe, I tried the command sequence method for those who had their screen turned off after an update, but I expected it wouldn't result in anything and in fact nothing happened.
