I just got hold of an Arduino UNO Q and started immediately to play with it, using the 2.3.5 version of the IDE. No problems from that respect, I could load a few simple sketches, all were OK. I then decided to install the Arduino Lab App and my troubles started. App duly installed (I’ve a Mac Mini M2 Pro with Tahoe 26.1), the app warns me that I’ve a certain number of elements not up-to-date, arduino-flasher-cli included. Downloaded and installed all the updates, run, from terminal, ./arduino-flasher-cli and get the expected message.
I then prepare the UNO Q for flashing (jumper included) and, launching the flasher, download the latest version of debian, when real flashing begins I get these messages:
Do you want to proceed and flash 20251024-412(latest) on the board? (yes/no) yes
Flashing with qdl
waiting for programmer...
Entity: line 3: parser error : Extra content at the end of the document
/>ta> ^
failed to parse firehose response
error flashing the board: signal: abort trap
Surely I must have done something seriously wrong, for being in haste, and can anybody help me out of this?
Incidentally, while typing this message I run the standard Arduino IDE and realized that the board doesn’t appear anymore in the list of ports and I’ve only an Arduino UNO Q connected via wifi which the IDE cannot handle.
Launching the Arduino Lab App it sees the board and asks me the password which happily accepts and, again, tells me to update the flasher. Skipping this step I find myself in the examples pages of the Arduino Lab App 0.2.0.
I beg forgiveness for all the mess and ask if there is any way of resetting everything to the status when I opened the box, this morning, and started playing around with the UNO Q. This time I’ll do everything slow and carefully (reading everything before anything else)
Many thanks in advance
I moved your topic to an appropriate forum category.

Thanks in advance for your cooperation.
My apologies, I browsed, quickly indeed, the various suggestions and, at the end, the “Development Tools” uncategorized seemed to me the most suitable but, it’s clear, I was wrong.
Many thanks for the correction
Apparently nobody cares about this kind of problem. I must be the only one to face it.
Said that, I purchased a second Uno Q and, this time, I followed to the letter the instruction to update Debian on the Uno Q. I didn’t deviate from what indicated in the text.
I've updated arduino-flasher-cli to the latest version (0.4.0)
I've checked that it was recognized and functional on my Mac OS 26.1
I've disconnected the board and reconnected it after installing the jumper
I ran the arduino-flasher-cli flash latest command and it started downloading the whole package. When it was time to write it to the Uno Q board I got exactly the same message as with the previous Uno Q board:
Flashing with qdl

Is anybody capable to help me out of this ?
Many thanks in advance to whomever will spend some time on it
Solved. I’ve read a post where a similar flashing issue was mentioned even if , in the error message there, USB was clearly mentioned while the error message I was encountering is a bit cryptic . I tried using an USB-C to USB-C cable instead of an USB-A to USB-C one and it worked
