Phone won't turn on.

I have a huawei m865 and after hard resetting it for a reason, it won't turn on anymore. To be specific, it does turn on but only if i connect it to the charger when the battery is out, but still the phone doesn't turn on and is stuck in the huawei "turning on" screen. I remember doing something to it in the factory reset mode but i don't remember. Could it be broken forever now because of what i did?
