So two days ago, I've been suffering from a message saying that the custom binary was blocked by the FRP lock. So I decided to factory reset within the phone itself and that hasn't worked. I tried to flash the stock with Odin but it gets stuck at "getting PIT for mapping" and stops and says "complete write operation failed". My phone is being detected in download mode. I've tried two different PCs. One doesn't even recognise the device and one does. I've even tried different cables but no luck. I am unable to enable usb debugging mode and that probably is a huge concern. I just want my device in working order. My Device: SM-G930F OS - Android Oreo 8.0 Any1 got any ideas?
