You have to install the packages from /home/.pk-zypp-… in recovery mode (not with SSH, but through option 3: shell). You must install them with rpm -Uvh. One of the many folders full of RPMs will allow you to install everything in that folder without conflicts. Then, another folder will allow you to install everything without conflicts, and so on. It’s a bit of trial and error figuring out which folder you will be able to install next, but keep going until you’ve finally installed everything.
After that, you can boot your phone normally and (only if you already had developer mode enabled in the settings before you installed this update!) SSH over WiFi.
