so I have a ZTE Engage old phone and no longer activated.. I have it connected to my wifi and logged into my google account.. I am receiving my email from GMAIL. But as soon as i try to update my apps or download something it gives me a RPC error.. I thought maybe i need to root my device but im sure i dont i just wanted to get it on wifi so kids could play with it.. Is that possible? it does not have a sd card in it i cannot find the one it came with
