[Q] Can't access sdcard in recovery mode
I want to upgrade my GT-P7310 from Samsung's version of Android 4.0.4 to CM 10.2 but I can't get root/su or Clockwork Recovery installed. When I go into recovery mode and select "apply update from external storage" it shows the error:
E:unknown volume for path [/sdcard]
There's an option to "apply update from cache" too, but /cache isn't writable without root.
I tried the downloading option (Odin) too, using Heimdall for Linux, but the recovery images I've downloaded aren't compatible with that (even after repacking from zip to tar.gz).
I also tried Bin4ry's rooting package (v33), but even after fixing the obvious bugs fixed it depends on remounting /system rw which doesn't work.
Does anyone know how to fix the unknown volume error or how to get Odin to work (preferably with Linux (Heimdall) rather than Windows)?
