Chosen Solution
I have done everything to restore it. When ever i do, it gives me the same error. However when i opened the phone, and applied pressure just on top of the sim card tray is, on the heat shield, the restore almost completed, but yet again the error then occoured. What is the solution to the problem
Error 9 on the iPhone 6 can be an issue with the connection between the CPU and the EEPROM. Applying pressure on the CPU (the heat shield above the SIM Tray) is the classic “tell”. This requires an advanced micro-soldering repair and may not be worth the expense, depending on where you are located, unless it;s for data recovery.
