ERROR: Firmware file block too large #214

Open jonathancross opened 1 year ago

jonathancross commented 1 year ago

Linux desktop GUI: v5.3.6 (App is up-to-date) Firmware installed: v2.1.0-prodc Bootloader: UNLOCKED BOOTLOADERv1

Issue:

When I try to upgrade to any of the firmware versions, I get an error message:

Last message received: UNLOCKED BOOTLOADERv1 RECEIVED OKFWUPDATE Error firmware file block too large

The desktop app then tells me the device is locked and to input my PIN, but it was not upgraded.

I checked the SHA-256 checksum, so I know the downloaded firmware file (Signed_OnlyKey_3_0_4_STD.txt - 429,285 bytes) was correct. I also tried with 4 earlier versions and got the same error.

Workaround:

I was able to upgrade via these steps:

  1. Put the device into config mode
  2. try to update (leading me to the backup step).
    • Note: The backup step seems to be a potential source of error -- skipping it seems to allow the firmware update to proceed, but I don't have enough info to determine cause-effect.
  3. Instead of supplying a backup passphrase, I Close the desktop app
  4. Restart the desktop app (OK still shows white light)
  5. Then try to update the firmware and it goes forward.

Some discussion about this same issue here:

https://onlykey.discourse.group/t/firmware-2-1-2-file-block-too-large/760

I got it working using from inside a Debian VM. Another user found this workaround:

When you put the onlykey in the computer, and it goes to the setup guide, if you have already entered a backup phrase…ignore it. Pull out the onlykey, put back in. Now it goes straight to load firmware, skipping the setup guide and this time it does update.
