Hey guys, I tried to flash my Model F with QMK Toolbox, which appears to be the preferred method, after making a new .hex keymap with the dev version of QMK configurator. I hit reset (Fn + Space + R) and flashed it, and it disconnected at the end of the process as expected. When I tried to reconnect though, I get nothing – no recognition that the keyboard has been plugged in from either of my Windows computers, and the keyboard itself doesn’t type anything. I can’t seem to get it into bootloader mode again either, to attempt the flash again. Can this be saved, or do I need to open up the back of the keyboard and reset the controller?
I really don’t want to have to because I don’t have any torx heads on hand so I have to grab and twist each screw out with a set of pliers to remove the back plate, and there are a lot of screws.
Solved! Thank you, Joe! Resetting PROG does not return the keyboard to any default keymap, but rather erases the stored keymap, meaning the keyboard won’t magically start typing after you hit reset. As the answer indicates, please have a software like QMK Toolbox or the Windows Device Manager open for visual verification that a plugged-in device has entered bootloader mode.
The keyboard may already be in bootloader mode (if so, it would say ATMEGA32 DFU in device manager, at least on Windows) – in that case you would use the atmel flip utility on windows to load the firmware. I am not familiar with other OSes so I recommend using Windows if you can have access to such a machine.
Under no circumstance would I recommend using anything but the correct torx bit – otherwise you will damage the keyboard case.
Unfortunately I have no idea what was done here so I can’t be of much help but as a last resort shorting PROG will work as these controllers cannot be bricked permanently to my knowledge.
Did you use the f77/wcass or f62/wcass selection in the QMK beta site? This is what is shown in the instructional firmware video. If you selected another option it may have resulted in what you are seeing.
I mistakenly used the /universal version as I didn’t catch the instruction to use the /wcass version, and I think that was the actual problem since QMK Toolbox still recognized and flashed my keyboard despite the fact that I should have used Atmel Flip.
I don’t see anything in Device Manager or the Control Panel’s Devices & Printers.
Shorting PROG didn’t seem to do anything, I’ve followed the instructions to hold it, plug in, and then remove the short quickly with a lot of different pieces of metal (including a spoon) to rule out the possibility that I might have been using a coated paperclip that won’t short.
Neither Atmel Flip nor the Pandrew utility can detect my keyboard.

Thanks for these tips, I will go back over my steps tonight. And sorry about commenting 3x, I just assumed due to a serious delay my comments didn’t arrive.
To the best of my memory I did use the wcass layout. I really appreciate the support, and if all else fails I’ll go buy a set of torx bits and open the back to short PROG.
