Phone will not boot into fastboot mode, phone will only boot into stock recovery
No matter what I try to do, when I turn on the phone (LeTV x800) with the power down button held in, the phone loads an image of a penguin and then reboots.
When I hold the power up button in and turn on the device it loads the stock recovery. But won't allow me to flash TWRP recovery which I have renamed to the devices required nomenclature (update.zip). It says it is corrupted.
