Any information regarding what you did with the Bunny before it entered this state might benefit the troubleshooting. Quote Link to comment Share on other sites More sharing options...
lllooo Posted November 14, 2023 Author Share Posted November 14, 2023 1.Set the switch to arming mode (closest to the USB port) 2.Plug the Bash Bunny into a USB port and unplug it immediately after the green LED turns off 3.Repeat step #2 three times 4.Plug the Bash Bunny into a USB port and wait approximately 5 minutes for it to reset. The LED will either show an alternating red/blue "police" pattern or blink red. 5.When the firmware recovery has completed, the Bash Bunny will reboot, indicated by the green LED, then go into arming mode, indicated by the blue LED. There were no operational errors following the official instructions Afterwards, a blue light - green light - pink light - blue light - followed by a continuous flashing blue light Fault reason: (apt update&&apt y full upgrade) has been updated once and will no longer be usable It seems that there is a major problem now, unable to access the serial port, and there is a serial port (due to device issues, Windows has stopped it). Request for USB configuration descriptor failed And I can't display the disk, I'm not sure if Linux is running properly now Is there any way to recover it Quote Link to comment Share on other sites More sharing options...

What does it come from? If the Bunny isn't possible to be accessed, there should be no way of getting any error message from it. 8 hours ago, lllooo said: apt y full upgrade A specific comment about this; you shouldn't ever do a Debian upgrade on the Bunny since it possibly will break features of the Bunny. It won't fully break it, but you might run into issues that makes it necessary to factory reset it. Quote Link to comment Share on other sites More sharing options...
lllooo Posted November 15, 2023 Author Share Posted November 15, 2023 After a brief red light, it kept flashing blue and it was useless to restore the factory. I estimate that the rootft system has been damaged, so it was not restored.

Is there any way to recover now that can only be processed through hardware means? Currently, there is no way to recover the serial port in the mode. The serial port should be simulated using a Linux driver, not similar to the hardware used in CH340. Otherwise, it should enter uboot Quote Link to comment Share on other sites More sharing options...
dark_pyrro Posted November 15, 2023 Share Posted November 15, 2023 So, it wasn't actually doing a successful factory reset then (given the LED pattern you describe). Regarding the factory reset process. Can you confirm that you did unplug the Bunny 4 (four) times when the green LED turns off. Just so that I can be sure you understood the instructions in the documentation correctly. The reason why I'm asking is that Bunny users have misunderstood the instructions before and just unplugged it 3 (three) times in total which is not enough for a factory reset. The below (that you quoted from the documentation) is a total of 4 (four) times, not 3 (three). 8 hours ago, lllooo said: 2.Plug the Bash Bunny into a USB port and unplug it immediately after the green LED turns off 3.Repeat step #2 three times Quote Link to comment Share on other sites More sharing options...

I have tried it three times, four times, five times, and six times, and this recovery mode is definitely not working. It uses bash recovery in/usr/local/bunny/, and there is basically no need to consider it in cases of system, driver, or file loss. Quote Link to comment Share on other sites More sharing options...

I feel that there is only one way to solve this situation now, which is to connect the motherboard through TTL, abort Uboot to enter the kernel, and decompress rootfs from the firmware in Uboot mode Quote Link to comment Share on other sites More sharing options...
dark_pyrro Posted November 15, 2023 Share Posted November 15, 2023 If that's your conclusion, then do it. It will void warranty though. Quote Link to comment Share on other sites More sharing options...
lllooo Posted November 15, 2023 Author Share Posted November 15, 2023 Thank you very much for your recent help. I also felt through the Linux embedded development documentation today that only this mode can save my bash. Very uncomfortable Quote Link to comment Share on other sites More sharing options...
