Help getting Hp EliteBook 820 G1 working with Mojave

Hey all, i've been trying to get mojave installed on my HP EliteBook 820 G1 with a Haswell i5-4210U and HD4400 graphics following this guide: but so far i cant even get the machine to boot into the installer. It always usually reboots after "End RandomSeed", or sometimes it will get to a "apfs_module_start:1393" and my flash drive turns off (it has an LED) and it hangs there for a few minutes before giving me the error logo. I've tried every other guide i could find, nothing seems to get me any farther. Any ideas?
