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

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!
