Does it matter that your edit effectively results in the digital signature (at the end of .fwh) now falling outside the range of the .LOD file?

Code:
Offset(h) 00       04       08       0C

00000100  E71A0E59 01000200 00000000 00001900

00000120  00000000 00A02400 00000000 00000000
                   ^^^^^^^^
                   size of payload = 0x24A000

00000130  00000000 00000000 00000000 0000CBEB

Dear Mr. SWM, how do you do? I have deleted the DEL header according to your method, but I still can't update the firmware. Is this due to a lack of verification? Could you please check it for me? The lod file I generated is as follows.

I would strip off the first 0x100 bytes. That said, I wouldn't use Dell firmware on a standard retail drive or any non-Dell drive. A firmware update typically targets only a few of the many firmware modules, so you may introduce compatibility problems with existing modules.
