Hi, i have General Mobile GM 5 that locked by FRP. I found this phone at jungle and i searched for its owner about 2 months. But i couldn't find so i decided to use it. But its locked by FRP and "fastboot oem unlock-go, fastboot erase frp..." doesn't work. So i don't know a synchronized account with this phone. I just drop my SG S3 Neo and its not working anymore. I want to use this but i can't. Waiting for help. Thanks.
