Boot the USB in a machine with a 64bit CPU. Doesn't matter what OS is on the machine (you don't use it).
Got FWUL persistent booted on 64bit machine. I have the phone connected in download mode as per the sample picture. However run I run SALT it gives "No device connected" error., so I'm unable to use any of the tools.
If I go into the Advanced menu and click the "Unlock G4 USU" option the error says "Your download mode version is not supported, downgrade to LP or MM!" which is confusing because the phone IS on native Lollipop?
Apologies for being so clueless but many thanks for your help and I can see that this is a very useful project once I learn how to use it :laugh:
