When I ADB devices, i see the serial # of my device properly. If I go into bootloader, when I fastboot devices, it comes up as all question marks (??????????????? fastboot). Windows properly sees my device as "Android Bootloader Interface". I am able to do basic commands (oem unlock, reboot-bootloader, etc). However I cannot push any files (root or custom recovery.) My DOS window just hangs and nothing transfers.
I googled for three hours and can't find if this is fixable or if I have to RMA. (And if I do RMA, how would I? I can't say I am having issues pushing custom recoveries to the device LOL)
Thanks in advance!
