That changed it so a hard reset will try to boot to main. If you can get to fastboot you can do "fastboot setvar bootmode diags" and then it will reset to diags.
If you have not done so alread, you should install the mmcblk0p2 with SSH preinstalled. You can debrick it in five minutes if you have that. You can install it from fastboot.
