Hi,

Firstly download ilo5_148.fwpkg then extract ilo5_148.bin file.

Then flash firmware.

Then you can upgrade ilo5_255 with same way.

Official road map below

UPGRADING FROM A PREVIOUS VERSION OF iLO

- Hewlett Packard Enterprise highly recommends a minimum firmware version of iLO 5 v2.41 or later.
- Direct upgrade to iLO 5 v2.55 is only supported for servers with iLO 5 v1.48 and above.
- On servers with an earlier version of iLO 5 installed, you first need to install iLO 5 v1.48,
and then install iLO 5 v2.55. For example, if a server has iLO 5 v1.10 installed, install
iLO 5 v1.48 first, and then install iLO 5 v2.55.
- Minimum supported iLO version for Gen 10 plus Intel platform is iLO 5 v2.42.

I have to add something....

Just got a warranty replacement system board for a BL460c Gen10 and it came with a VERY old firmware iLO 1.30. I tried to update to 1.40 as recommended but the update failed with "make sure file signature... blabla"

Working update path in this case:

1.30 -> 1.35 -> 1.40 -> 2.14 ->2.41 -> 2.71
(Edit: When you have 1.45 or newer, you can go directly to the newest version)

You MUST use these steps or it will not work. Direct update from 1.40 to 2.71 for example does not work. Maybe other versions may work but these are the numers I used.

Adding another thing:
I just had an ML110 Gen10 with the exact same issue described here.
But despite trying your chain it didn't want to update because of the error the iLO gave me.

To solve this I had to reset the iLO and after doing it, I was able to do the update chain (a bit less though)
My chain: 1.37 (current) -> 1.40 (extracted .bin) -> 2.41 (extracted .bin) -> SPP 2022.03
