OP9 Lemonade kInstallDeviceOpenError

• /e/ version: 1.7-S
• Device model(s): lemonade
• Developer mode enabled: yes
• Device rooted: no
• Trackers blocker enabled: yes

Summary

Sideload update from 1.6-R to 1.7-S went wrong somewhere. Got success in the terminal, but device went into a bootloop. Spent several hours trying to manually flash partitions with no luck, looks like this messed the Super partition, as now I get kInstallDeviceOpenError while trying to sideload and Could not open super partition when I tried to fastboot delete-logical-partition <multiple_partitions>

The problem

Super partition corrupted

Update from 1.6-R to 1.7-S via sideload and manually corrupt the Super partition on top of it.

No logical partitions under Super.

Proper Super with logical partitions under it, working ADB sideload of the OTA updates,

Possible fixes

I suspect (hope) an appropriate super_empty.img would help me, but I couldn't figure out how to make it on my own. Maybe somebody from the /e/ team would?

I really hope to fix it without losing userdata, otherwise I suppose MSM tools would restore the stock ROM.
