Hello amr;
First, EPROM cards for the S7-400 CPUs:
6ES7952-0KF00-0AA0 SIMATIC S7, MEMORY CARD FOR S7-400, LONG VERSION, 5V FLASH-EPROM, 64 KBYTES
6ES7952-0KH00-0AA0 SIMATIC S7, MEMORY CARD FOR S7-400, LONG VERSION, 5V FLASH-EPROM, 256 KBYTES
6ES7952-1KK00-0AA0 SIMATIC S7, MEMORY CARD FOR S7-400, LONG VERSION, 5V FLASH-EPROM, 1 MBYTE
6ES7952-1KL00-0AA0 SIMATIC S7, MEMORY CARD FOR S7-400, LONG VERSION, 5V FLASH-EPROM, 2 MBYTES
6ES7952-1KM00-0AA0 SIMATIC S7, MEMORY CARD FOR S7-400, LONG VERSION, 5V FLASH-EPROM, 4 MBYTES
6ES7952-1KP00-0AA0 SIMATIC S7, MEMORY CARD FOR S7-400, LONG VERSION, 5V FLASH-EPROM, 8 MBYTES

To load the program into the EPROM, once you have sloted it in the CPU, use the "Copy RAM to ROM" command in Step 7 Simatic Manager.

Now, the most important issue.
Why is your CPU failing? With all LEDs flashing, this means a catastrophic unrecoverable fault...
Have you opened the Diagnostic Buffer of the CPU to look at the system messages that are collected there? If you have the required OBs loaded in your user program, the Diagnostic Buffer should have details on the cause of the problem.
The easiest way to open the diagnostic buffer is to go Online with the CPU while looking at the HWConfig editor. Double-clicking on all the modules that show up with a red cross will get you diagnostic information on each of them. You can save the logs (as text files)and show them here if the messages are hard to understand, we have some experience here on the forum.
And we are willing to help.
Hope this helps,
