Prusa mini has trouble booting
Upon power-on, the screen ends up at the language-selection screen. I select my language, but it basically reboots at that point. This is the installed 4.2.0 firmware I believe.
If I use a formatted USB drive with the newer 4.2.1 version as the only file, it does recognize that the file is there. I have the option of installing that or skipping (the selector wheel works fine). Either FLASH or SKIP ends up rebooting without installing 4.2.1, and we're back at that selection screen.
Any ideas?
Thanks in advance.

I would suggest testing a different USB drive if you're using the included USB. Also, download the firmware file again, as it might be slightly corrupt and not passing a signature test.
I think I know, I don’t think I know. I don’t think I think I know, I don’t think I think.

Ok - easy to try. Found a USB drive and formatted, new download from https://cdn.prusa3d.com/downloads/firmware/prusa3d_fw_4_2_1_MINI.zip. Moved the prusa3d_fw_4_2_1_MINI.bbf file on the new drive, power on/boot. Same behavior.
Note the original weird behavior is w/out USB drive. That's just my attempt to fix by loading updated firmware.

Can you do a factory reset or does the 'boot loop' prevent you getting to the menus? Clutching at straws but it's worth checking all the cables are in the right place and seated correctly on the buddy board.
If you can't reset, I'd suggest talking to support using the web chat on the e-shop page, they'll be able to help with diagnosis and send spare parts if necessary

After resetting or switch on the printer, try shortly after double-clicking the control button. This should work normally.

Have tried double-clicking on the panel and small recessed black button (near power switch), same thing happens.
Will go back and double-check connections seated later.
Thanks for the helpful suggestions.

Since the encoder works but the click doesn't I would suspect that the press of the button triggers maybe a short circuit that resets the whole machine. Contacting the chat would be the best idea because for me it seems like a hardware problem.
