SRW248G4P - (!)Loader Binary checksum error - ERR Runtime Loading Fail - System Halt.

Question

We have this 48 port switch in our engineering department, and it basically stopped passing network traffic.
When connecting to the Console port and power cycling the switch, this is what I see:
Image Loader 1.0.1
Loading Diagnostic Image File : SRW224G4P_SRW248G4P_boot.bix
Diagnostic 1.0.1
User Mode
--- Performing Power-On Self Tests (POST) ---

UART Loopback Test ........... PASS
POE UART Loopback Test ....... PASS
DRAM Test .................... PASS
Timer Test ................... PASS
Done All Pass.
------------------ DONE ---------------------
(!)Loader Binary checksum error
<ERR> Runtime Loading Fail - System Halt.
This error obviously doesn't look "normal".
When pressing CTRL-U, I get the following screen:

I've tried to update the "SRW224G4P_SRW248G4P_image_v1310.bix" file using Xmodem download, but since I really wasn't sure how to use this boot loader tool, I haven't been successful at doing that, nor do I even know if that's the solution for the problem that I'm having.

I'm guessing that I'll need to contact Cisco tech support, although at least through their web site, they make that nearly impossible to accomplish.
Does anyone have any suggestions on what may have happened to our switch and what I should do to recover? Of course we're about to start a time-critical round of product testing, and without this switch, I'm dead in the water.  And it's not like we have a spare 48-port PoE switch lying around.

Hello,
I got the same issue. After downloading and uploading the firmware, I got the following result and all LED on the switch are glowing. Could you please help on this issue? Where can I find the right firmware. I also have Image loader 1.0.1.
