I've yet to encounter a phone that can't reset unless the phone is dead and gone.
I take it you pulled the battery, SIM and memory card then put the battery in to try again.
My Huawei Ascend y511 u30 have a big problem maybe. All of my apps has stopped. Its always pop up has stopped has has stopped. Seconds per seconds. All i can do is click ok ok almost 500x. I cant reset my phone. Even i reset via hard reset the result is the same all my apps cant delete and cant be reformat. Any solution. Please
