I added init=/bin/sh to my cmdline.txt in an attempt to troubleshoot this problem, but upon booting I land at the normal credentials prompt.
I'm using a MicroSD adapter to edit the file with a Windows text editor, as that's the only other running OS I have available to me. The card apparently contains two partitions, as one is mounted (FAT32) but not the other (probably ext4). DISKPART doesn't show the second one either, nor does Disk Management.
Should I be editing a cmdline.txt file on the ext4 partition as well?
