This technique is called Reflow. You must know what you are trying to do, first of all you can't use an hairdryer or an hotgun, because hairdryer does not spread properly and does not have the C°/F° required for doing a reflow, you can cause several damage on the nearby components. No hotguns because those guns are way too much hotter and as @Josh W said there is no way to know how much really the hotgun temperature is running (you could use it but not in a newbie hands). You need an SMD rework station for doing this job around 280/310 C° (536/590 F°) and a bit of practice. I suggest you to bring your iphone at your local repair shop and the best you can do is to explain every single movement that you did. Sorry for my bad english.

Could be IC video or IC Backlight problem. If you see only those flashes without any video feedback could be ic video inductor issues or (viceversa) could be IC backlight inductor problem. Here i post a "very simple paesant schematic" :)

Hi, have you performed a factory data reset + clean cache? Could be a software issues

Hi, have you performed a battery recalibration? To be honest no one battery apps are good, they just cancel some logs from your device (in few words) Here is how to perform a battery recalibration. How to calibrate a smartphone battery: Let the device reach 0% and let it shut down till you can not even turn it on Connect the battery rechargerwall and let the device reach 100% battery without turn it on. Once the device reached the 100% battery let it connected for other 2 hours (without turn it on) Once the 2 hours are passed with the rechargerwall battery connected to the electricy, turn on your device for 20 min, after that turn it off. Once you turned off the device disconnect the rechargerwall from the wall then disconnect the usb data cable from rechargerwall battery. After that reconnect the usb data cable to the rechargerwall battery and then reconnect the rechargerwall battery to the wall electricity This operation should be repeated for 3 days in a row. Do not perform this operation more than 3...

Hi to everyone, i would like to update my question and how i fixed the issues, so i fixed the issues by replacing the usb connector board (bought on a famous auction site) and after that you have to (sadly) re-assemble the complete case in order to your mobile network work fine. The latest step is really important because in the backcase (inside) there are the antenna's flex's (the white one) otherwise you are unable to get any mobile data, so is not like the other smartphones. Hope this will help someone.
