Reported Issues:

Issue: I have the PG05IMG.zip file on my sd card but when I boot into bootloader it doesn’t find it and begin the update.

Solution: Take your sd card out of your phone and put it into an SD Card reader (so we can plug it into the computer without the phone). Then format it by right clicking the drive that pops up on the computer when you plug it in and select Format. Once done, retransfer the PG05IMG.zip to the sd card and then remove it from the computer and put it back into the phone. Now, boot into bootloader and try again.
