Please suggest somewhere else I should post this. I took an OTA update last night for Lineage4microG and my OnePlus8T just bootlooped. I tried downloading and manually side loading both the most recent and previous versions, but they keep failing with a kInstallDeviceOpenError. I am desperate to get back into my device without wiping the data.
If you don’t have ADB through the recovery, you may install one that supports it, or instead of installing you should be able to just boot it with the fastboot command. Be sure to use a recovery that is at least somewhat popular.
