Hi all, I hope you can help. I don't know anything about Android phones so please be patient with me. (I'm not a developer and just use the phone for calling overseas, surfing the net) I left my 14 yr old son with a spare phone of mine (Redmi) during last week whilst I was traveling. Came back last night and the phone says: "root permission is disabled in miui stable version. please install miui beta version to activate root permissions site:xiaomi.eu" I'm not sure if this means it's a hardware or software issue but can I fix it at home or do I have to take it to a specialist? - hope someone can guide me here. Thanks in advance!
