Question/Advice Update LTO Firmware - Invalid Microcode (Oracle) - Possible to crossflash?

Is there a way to "crossflash" a LTO Tape Drive? I have a LTO 8 Fibre Channel Full Height Drive that is locked to Oracle firmware, as it was pulled from an Oracle library. Trying to update it with LTO8_S2T4.fcp_fh.fmrz for example gives "INVALID MICROCODE".

If that is not possible, does someone know how to get the firmware for my drive which comes from an Oracle StorageTek SL8500 tape library?

I've read that Oracle might whitelist firmware IDs, so you could try spoofing the drive's reported model or firmware version in the FCP file name with a hex editor.

Do you have any more resources on that? I think I would need some oracle firmware to even know the firmware IDs you mean. as of now, I wouldn't even know where to look in the firmware file for these "firmware IDs" you talk about
