Hello! I received an iphone 4 from my friend. The problem is, the iPhone stuck in boot loop. He told me, that he jailbreaked it and tried to update, yeah, i cursed him for that. Now, to the main problem. I stuck on boot loop, iPhone battery is empty. I've tried recovery from itunes. Tried in recovery mode and even DFU mode. Tried to downgrade to 4.3.2, tried to reflash 7.0.4 which he updated into. Please, help me. what to do?

I dont have any shsh bloobs etc. I have only cable and phone.
