I have a OnePlus 6 device, with which I was using LineageOS for a while. I reinstalled OxygenOS 9, by doing the following:
- In LineageOS recovery, sideloaded TWRP (I couldn't sideload OxygenOS, because verification failed)
- In TWRP, installed OxygenOS
- In OxygenOS recovery, wiped system and cache
OxygenOS runs, but I cannot access /sdcard. I can access OxygenOS via adb, but I'm unable to sideload anything - trying to do so generates "error: closed".
Is there any way to regain access to /sdcard (preferably, without deleting the data that's on it)?
