My jailbroken iPhone 4 with firmware 4.1 has become completely unresponsive to anything. I was playing video games while updating my packages through Cydia and when I looked back my phone was dead. I thought I could easily fix this by putting it into DFU mode and connecting it to my PC but I was wrong.
The PC couldn't recognize the device even though I used 2 different USB cables and 2 different computers. Using programs like 'ZiPhone,' 'TinyUmberella,' and 'RecBoot' didn't help. I have used Apple's troubleshooting to the iPhone not being recognized by Windows due to driver installation issues. iTunes is also unable to detect the device and I have called my phone resulting in no response. Basically the phone is dead.
The updates probably have messed with the software and may have bricked my phone. Right now I'm looking for any answers helping me fix my phone or confirm my conclusion that the phone is dead.
1) put it into Recovery Mode. Looks like RecBoot failed on you, try Blackra1n. I have forced my phones into Recovery with Blackra1n before and was able to have iTunes detect it. If that doesn't work then...
2) take it to Apple and get another. If the phone can't even be turned on or detected by a computer, they likely won't detect that you were jailbroken.
BlackRa1n was unable to detect it too. Looks like I'll have to visit Apple. My worries are that if they determine it was jail broken my warranty is void and I won't get a replacement.
I'm going to schedule an appointment, I'll let you guys know how it goes.
Haha it would be funny if it was the same guy at my Apple Store. Besides I spent hours searching for a solution and came across stories of guys who got their devices serviced.
