Pocket Reform Stuck At Boot—OLED won't pull up menu

[pff]

There are 2 different issues you need to deal with, one is turning on the pocket without a working keyboard, another is re-flashing the keyboard.

If the pocket is on, you can re-flash a “soft-bricked” keyboard by putting in programming mode manually, pressing reset/prog in the keyboard PCB.

Flashing the keyboard firmware

I just failed to flash the keyboard firmware for my pocket :grimacing:Well it all succeeded (after putting the keyboard in programming mode), but I think moving the enter key down one row in matrix.h means I can’t use Hyper+Enter in new or old position to boot. Is that expected? The sources made me think it should be fine. Now Hyper+anykey gives me “Press Hyper + Enter for menu. Hold to power up”… have I any options other than disassembly to put the controller in factory mode now?

But… first you need to turn your pocket on without a keyboard. As far as I can tell this requires re-flashing the system controller firmware to “factory mode” which turns on the computer when the power is connected. This can be done from another working computer, through the usb-c connector in the motherboard that accessible after opening the pocket.

There is some information on how to do this here:

Reprogramming the Pocket Keyboard

Yes, it totally is a very good and appreciated idea to work on things like that, if you have the time. I wrote the part of the handbook for flashing the keyboard today. The handbook is not 100% done yet, but you can already use these instructions: Beware that the main issue with bricking the keyboard is that you can’t easily turn the system on. For that, you would need a modified version of the System Controller firmware (on the RP2040 on the motherboard) which auto-powers the device the firs…
