R815 & H310 - impossible to update firmware with OMSA

hi everybody
I wonder if any of you had any luck updating H310 in R815 
using OMSA?
it fails for me, with:

..
Checking PERC H310 Adapter Controller 0 Firmware - 20.12.1-0002
     Available: 
pci_firmware(ven_0x1000_dev_0x0073_subven_0x1028_subdev_0x1f4e) 
- 20.13.1-0002
     Found Update: 
pci_firmware(ven_0x1000_dev_0x0073_subven_0x1028_subdev_0x1f4e) 
- 20.13.1-0002
...

which is already weir, if my logic of above is ok then it's 
trying to update the same versions?
and I get:
