Hi, got the core prime. Was locked to a network so paid to have it unlocked (standard stuff) when we got the phone back we logged into the google account and the pone shut down. When turned back on it said in red writing in the top corner "Custom Binary blocked by FRP Lock then shuts off. We took it to the shop and restored it but once again when we logged back into google the phone shut down again and said the same message. I am stumped what to do next. Just bought the phone and I don't want to have wasted the money Can someone please help me?
