Nice Nano cannot update manually and locked out of ZMK Studio
Hi there, I have been using the keymap editor for a long time to build my firmware and then I flash it manually. Not too long ago I switched to ZMK studio and when I was updating my layouts I forgot to add a sticky layer key to my new layer and I have lost access to my unlock button. I tried to go back to my last keymap editor firmware because I know that the unlock key was on that one but for some reason, I cannot get my nano to flash the firmware anymore. I go through the process but it doesn't actually update. So I feel a bit stuck now and do not know what to do.

Sorry to hear you're having trouble! It sounds like you're locked out of your keyboard.
First, try entering the bootloader by double-tapping the reset button. If that doesn't work, see this guide: https://docs.typeractive.xyz/troubleshooting/entering-bootloader
Then, try flashing the default firmware to see if that fixes the issue: https://docs.typeractive.xyz/build-guides/corne-wireless/firmware
Let me know if that helps! If not, tag me again and we can troubleshoot further.

If you're not familiar, ZMK is a wireless-focused firmware, and it powers our Corne Wireless.
I can get into the bootloader but when I try flashing the new firmware nothing changes
Thanks for the update.
A couple of things to check:
* Try a different USB cable.
* Try a different device.
* Make sure the power switch is on after flashing.
If that doesn't work, try manually shorting the RST and GND pins on the nice!nano with metal tweezers. Double-tap to enter the bootloader this way, too.

This could be a case where you've hit a fun(?) edge case.. is the new firmware you're flashing with
CONFIG_ZMK_STUDIO_LOCKING set to y still? I think that controls the ZMK Studio lock behaviour but at the same time whatever you had loaded via zmk studio will persist as your keymaps..
(TL;DR - try load your firmware with CONFIG_ZMK_STUDIO_LOCKING=n so you can get ZMK studio access again, then get ZMK studio to reset back your keymaps to default so youre back to what your firmware is)well, I got it to manually flash by CONFIG_ZMK_STUDIO=n and CONFIG_ZMK_STUDIO_LOCKING=n. So thats a start
Good sign. If i understand that correctly, it'll make it so the board doesn't read anything ZMK studio related but I don't know if it'll reset the stored config. To do that, it'd be ZMK_STUDIO on, STUDIO_LOCKING off and then connect to it and do the reset that was as my only idea
