Today I resetted my GT-N5110 by choosing the option in the Android system recovery. I did it because after the update to Android 4.2.2 I got via OTA some Apps were determinated repeatedly. I also re-initialized the Firmware via Kies.
But, wenn I run Android system recovery it says "No command" an when I try to wipe the cache partition it says "Error!".
I never rooted or used a custom rom.
Does anyone have an idea??
