I am using the official Lenovo one, its in the verified USB adapters list. The hardware string is:
USB\VID_17EF&PID_7205&REV_3000
USB\VID_17EF&PID_7205
It is the exact same adapter I’m just changing what image is associated with it.
snp.efi, and realtek.efi yielded the same issue stuck at init.xz
snponly.efi gets farther, and is capturing the image currently on the 2nd boot, the first time ended in an error. I think that may have been the trick. I will update if it successfully finishes and can push it back out.
