darth Thanks! I have fastboot drivers and it worked on other devices. Even on the Flip 2 a different phone. Now it isn't working. I tried updating the device manager with the drivers manually, but nothing happens. I am on Windows 10. Driver signing is turned off. I tried MediaTek Android ADB interface version 11.0.0.0 Dated 8/28/14. I also tried Google Android ADB Interface version 9.0.0.0 dated 1/27/14 and also Google Android Bootloader Interface same version and date. Can you share what fastboot drivers you have working?
Edit: I removed all mediatek drivers and reinstalled them. It works now. Thanks!
