To those of you who may be suffering from this Binary Blocked by FRP Lock mode yu may need to be aware this work is still in progress. Not all devices have been fixed at this time and there are some that we are still working on. This block usually comes from a result of trying to flash a device to Root it and/or run a different ROM. Those methods used bad or corrupt files that overloaded the Binaries that the device runs from This is the operating system of your device and why you may now be in Binary lock. My post that can be found on XDA Developers tries to offer what infomation I have found and used to get past this difficulty myself. But in most cases offers some understanding of this and how it can be fixed. If you have made it this far in your research to correct this difficulty for yourself or a friend I will offer a link to my post and bring an end to all the useless searching you may have done so far. I have more than one post about this subject in the forum which are difficult to find for people that are not familiar with our forum. But here is my personal post about this. Please note that the files needed for each device are specific to that device. Good luck
