Pixhawk 2.4.8 possibly bricked?

Hi everyone
I’m having trouble with my Pixhawk 2.4.8 and I need some help.
The device was working fine before but now when I power it on, I’m experiencing these issues, even though I haven’t made any changes to the electronic connections after it was working:
The main RGB LED is solid cyan.
On the IO side, the B/E LED is solid orange, and the ACT LED is blinking blue.
Neither of the LEDs on the FMU side are lighting up.
No USB device is recognized when I plug the device into my computer via USB (lsusb doesn’t show anything).
No log file is being generated on the SD card.
Does anyone have any idea what might be causing these issues? Any help from anyone who has encountered this issue before or knows the solution would be greatly appreciated.

you could try and see if it responds to DFU mode
