qFlipper@Linux: Co-Processor Firmware Download ERROR: Can’t start FUS: Failed to initiate transaction

Hello,

I have the FlipperZero in recovery mode (DFU) - exactly like in the docs - qFlipper application window closes and my FlipperZero is completely dead. (qFlipper run’s on Linux 5.4.0-135-generic #152~18.04.2-Ubuntu SMP Tue Nov 29 08:23:49 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux)

the log of the process:

I tried again to activate the FlipperZero with normal reboot and with recovery mode. The device reconnects to qFlipper but the repair process crashes again.

It seems to be an interruption of the USB connection (see “LIBUSB_ERROR_NO_DEVICE” in the log file) - BUT I have to ignore errors - see the hints in the logs - until matching opening message. I see no opening message, qFlipper terminate and FlipperZero it’s still dead.

Is there a well known linux-reference implementation - maybe even a VM image - of Linux with qFlipper?

What’s the cause of: “Co-Processor Firmware Download @Oloqiade ERROR: Can’t start FUS: Failed to initiate transaction.”?

If you get this figured out let please let us know. I’ve seen others with a similar error but I’m not sure if they got it resolved. Here are a few things I can suggest you double check.

  • Try a fresh SD card
  • Try a different USB port. Avoid hubs if possible.
  • Reboot the computer.
  • Unplug the Flipper, do a normal reboot, then plug it in overnight to charge. You may not see normal charge indicators if the battery is extremely flat.

Just found your post after creating mine. I am experiencing the same exact issue. Im also running linux.

Flipper is bricked and qFlipper crashes with the same error log every time. Have tried different cables, sd cards, resets, etc. Hoping someone can figure this out. I havent even got to use mine yet! 🫥

same here6, try all cases no one helped(

Also have the exact same problem. Formatting or using another SD card doesn’t help.

The Flipper screen is since completely dark too.
