Bypass google lock on kyocera E6388 - Kyocera Cell Phones

All I can suggest for this is to take it to mobile phone specialist. They will have the tools to help. There is a possibility they will have to do a 'Hard' reset which often mean resetting to phone to factory settings. This means you risk losing your personal information like phone numbers, Photos and stuff you've saved on the phone. Pin codes are a security feature so naturally are hard to bypass.

Good Morning,
Sorry to hear you are locked out of your phone. I have literally Google Bypassed 6 phones within the last week and a half so I know how frustrating this can be! First of all you can either use OTG Cable or regular USB and laptop or desktop, be sure to install the Kyocera USB drivers, then you need to search for Kyocera FRP Bypass apk, also download the newest version of Odin3 and then it will take you step by step. Hope this helps and Good Luck!

You will need to call your cellphone provider. They should have a way to unlock it.
