IPhone blinking Apple logo

I have an iPhone 4 that started randomly blinking the apple logo. We've tried hard reset, and everything. Nothing seems to work. The only thing the Google told us was we had to restore it. We get to the DFU mode, plug it in, and when we go to restore it, it asks to restore and update. It can't be updated anymore and says an error, and there's no option to just restore the phone. What do I do?

Seems to stuck on logo. Try this 1. Hold the Down Volume button and Home and Power buttons all at exact same time for 5 seconds 2. Youll see Progressive Bar reach almost to the Half Way point 3. Release all three buttons n let it loading n proccesing and that should get you back to normal
