Title: Bootloader Stuck on ICX7150-C12P, Firmware Update Fails with CRC Mismatch Errors

[nc244]

I’m currently trying to recover a Ruckus ICX7150-C12P switch that is stuck in bootloader mode after a power outage. The switch’s system LED is solid amber and no access points connected have power.

What I’m Seeing:

• When connected via serial console (USB-to-serial) at 9600 baud, I reach the bootloader prompt.

• The bootloader attempts to load the firmware file named SPR08090d.bin via TFTP.

• I have set up a TFTP server on macOS, serving files from /private/tftpboot.

• I placed the firmware files (SPR08090f.bin, SPS08090f.bin, SPR08095gufi.bin, SPS08095gufi.bin) in /private/tftpboot.

• I renamed SPR08090f.bin to SPR08090d.bin to match what the bootloader requests.

What I’ve Tried:

• Verified TFTP server is running and transferring files successfully with zero packet loss.

• Ensured IP addresses and network settings are correct between switch and TFTP server.

• Attempted update commands from the bootloader:

  • update_primary SPR08090d.bin

  • update_primary (default to the renamed file)

• Each time, the switch reports CRC mismatch errors or invalid firmware image headers.

• Tried multiple firmware versions from Ruckus website (08.0.90f, 08.0.95g), but none work without mismatch errors.

• Renaming files to match bootloader expected names doesn’t fix the problem.

• Asked Ruckus support to provide the original SPR08090d.bin firmware as it seems the bootloader requires this exact version.

What I Need Help With:

• Confirming the exact firmware version and file required to recover this switch from bootloader mode.

• Instructions or tools to recover from this state without risking bricking the device.

• Any alternative recovery methods (e.g., USB flash recovery, serial recovery).

• Advice on upgrading bootloader or firmware in this stuck state.

Thank you in advance for any guidance or assistance!
