I was trying to install a TWRP recovery, the phone rebooted and it's stuck at the Ascend logo screen. It won't turn off, and no combination of power and volume buttons will make it do anything at all. It just stays at that screen until the battery goes dead. Once I plug in the charger it just starts up back to the logo screen and hangs.
Holding the power button, either alone or with other combos of volume buttons, causes the phone to power off and then it automatically restarts to the logo screen and hangs.
The LED is slowly pulsing an amber color.
ADB doesn't recognize it ("device not found").
Tried putting the stock ROM update into a dload folder on the SD card but it's not doing anything, even with the power+volume combo.
So Huawei is ready to send a messenger to pick up my phone for repair (which I bet they will charge me for). Does anyone have a suggestion I should try before I send it back?
