Nope. IT firmware is for the 'plain' mptsas (LSI SAS 1078) only. PERC6/i is based upon the 'Megaraid' SAS 1078, which is using the same SAS chip but has an additional (hardware) RAID controller. You cannot change the firmware here. And yes, megacli is notoriously tricky to invoke. It really needs to get used to.
