How do I unbrick an iPhone 4?

[Intell]

With my dead iPhone 4, would it work if I buy an official charger from Apple.com instead of buying third party chargers.

Not likely.

Not likely.

I am not interested but just out of curiosity, what is required and what has to be done for repair to replace the charging circuit and bring the iPhone back to life? Once again I am not going to pay for repair.

Could be a number of things. It could be something as simple as battery failure or something more serious like logic board failure. So its hard to tell exactly.

I just tried redsn0w just for fun to see exactly what state it would read if any or even what error messages if any. It says "connect acf2 device in normal mode". Does this mean anything and what does it mean and how to connect acf2 device in normal mode?

 

[php111]

I cannot find device information to acf2 on iPhone devices, but acf2 stands for Access Control Facility which I do not know what it means. So, why is refsn0w saying connect the acf2 device in normal mode?

Could someone please answer my last two replies?

I guess no one is going to answer?

redsn0w says that because it is waiting for a device to be connected since it cannot see your dead iPhone.

I am going to the Apple store today to see what is wrong with my iPhone.

Based on these two criterias, will they accept it and tell me what is wrong with it and give me a cost to fix it?

1.) The back is cracked because I dropped it accidentally.

2.) Before the phone went dead I had a jailbreak on it.
