How do I unbrick an older iPhone model which is the iPhone 4. Its CDMA so carrier is Verizon. I think it bricked earlier this year or sometime last year and I could not live without a phone so I activated my Galaxy S3 and I miss the iPhone 4 including my favorite which is FLEX. How it happened? Well, I was trying to charge it using broken chargers of Apple chargers and non-Apple chargers. Now, I have a working charger but it will not to this day charge my phone. I know in the past it will not even recognize in iTunes nor TU nor anything else and it will not even turn on. Could anyone please help? Thank you!
