Drop Alt Device not Found When Flashing Firmware

I compiled some new firmware for my Alt keyboard through the web tool, downloaded the latest distribution of the firmware loader (for MacOS) and attempted to load the firmware onto the keyboard. I put the keyboard into DFU mode (I tried doing this by pressing fn+b and also using the reset button on the back with a pin) but the firmware loader did not find the device on any port. It just tries "scanning for device for 60 seconds" and then nothing happens. This is a brand new keyboard I just got in the mail today. I used the original cable on multiple usb ports. The keyboard works fine, I just can't flash the firmware. Has anyone run into this issue before?

OK. I think I got it fixed. There are two issues. One is the chipID issue, the other one is the applet-flash-*.bin file name issue. Here are the files for flash firmware on Mac.

Same problem here. Just received the keyboard today. Keyboard works great! Just can not flash firmware... Tried all USB ports on my MacBook and both ports on the keyboard. Tried Sudo.. None of these works.

I also have this problem and I think we are in the same batch, I tried multiple computers and cables but it does not seem like the software recognizes my alt?

*Help* Screw in stabilizers not fitting in Dropshift V2 keyboard
I'm trying to build a mechanical keyboard with screw in stabilizers, I've build some mechanical keyboards with click-in stabilizers, never with screw in. Somehow one of the pins of the metal top-part collides with the screw in stabilizer of the numpad "enter key". I already tried grinding of a bit of the pin that collides with the stabilizer, but unfortunately I can't make it fit/close properly. You can see that the pin of the toppart leaves a mark on the bottompart of the stabilizer, see picture 2. What am I missing? Using Durock V2 in a Dropshift fullsize V2. See pictures below, thanks in advance!

Want to build a Clicky Mech Keyboard. Where to begin?
Hello all. Am brand new to the idea of building my own keyboard. Have not a clue where to begin this process. I am a Sim Game enthusiast. American Truck Sim, DCS Flight Sim and goes from there. Need some real help on where to start for making my own Full Size, Clickey Mechanical KB. I want each key to have its own backlighting. Are there keys that are better than others for this? Is there a great spot on site for a person who has never even taken a keyboard apart? Let alone fixed or built one? I would like it to fit my theme of Red and Black. Yet maybe have the option of changing things up a bit. Any help at all would be greatly appreciated. Thank you all kindly, Durazell

Does the ALT v2 PCBA support USB-C e-marked cables?
Currently my ALT v1 does not work with e-marked USB-C cables. I was wondering if the v2 PCBA does support these types of cables (thunderbolt 4 cable for example)?
