ROMTool is a full flasher, nothing more. It can't update your BootROM in the way that efiflasher do.My issue is this. I want to update the BootROM to 138.0.0.0.0 on the MP5,1 but somehow it skipped that part. Also i don't have a Metal GPU, only a stock 5770.
Is there a way to force the firmware update without Metal? Does ROMTool do this in a few easy clicks ?
I think this info would be very helpful for people stuck in this position such as myself.
To bypass the Metal requirement of EfiUpdater2, you have to extract your hardware identifiers from your current BootROM, then insert all that correctly into MP51.fd. It's simple once you have the intermediate files, but it's a expert job to create them correctly. I'll PM you.
