Errors that may appear when flashing iPhone firmware

Now let’s explain the error codes that you may encounter when updating or flashing your iPhone.

Error (1) or (-1)

There are numerous descriptions on the Internet where, to eliminate error (1) during iPhone firmware, they advise downloading the firmware file again or changing the USB cable. However, not everything is so simple: in 99% of cases such actions will not solve this problem.

If the iPhone is not flashed, and iTunes displays an error (1) or (-1), then this indicates obvious hardware problems with the gadget. Often the cause of these problems is a malfunction of the modem chip (radio module) or flash memory.

Only a professional from the service center can determine the exact cause of the malfunction and how to solve it. Therefore, if your iPhone cannot be flashed and this error is displayed in iTunes, you need to visit a specialized workshop.

Error (3)

The error is a hardware malfunction of the radio module. Often, error (3) is displayed in iTunes when flashing the iPhone modem firmware. It is unlikely that you will be able to resolve the issue yourself without visiting a service center.

Error (9)

This type of error when flashing an iPhone says that during the firmware procedure, a gap occurs between the gadget and the computer. During the installation of the firmware, the iPhone turns off. The reasons for this behavior of the device are different:

• Problems in the power supply circuit of the processor board.
• Battery problems.
• Hardware failure of the bottom connector.
• Violation of the integrity of the firmware file.
• Problems with the USB interface.

Another error (9) during iPhone firmware may indicate complex hardware problems with the components of the processor board (central processor, power controller, NAND Flash memory). If the iPhone cannot be flashed and this error is displayed in iTunes, then it can only be resolved in a service center. Only after technical diagnostics of the gadget can you find out the time and cost of repair work.

Error (14)

When flashing iPhone firmware, error (14) can be both hardware and software in nature. Another problem tells the user that during the firmware update the gadget was entered into an incorrect mode (Recovery or DFU), or it is not necessary to update the firmware, but to restore it from scratch (this could happen if you update the firmware by “jumping” through several software versions.” ).

In this case, the solution may be to restore the iPhone software from scratch. If the gadget is then flashed normally, activated and works stably, then this error has been solved and you just need to think about how the lost information from the iPhone can be returned. If the iPhone still cannot be flashed and constantly displays the same error, then you need to contact a service center to diagnose the gadget and clarify the reasons for the error and eliminate them.

Updating system drivers

This procedure will be useful in any case. Over time, old drivers slow down the system and are unable to interact properly with modern programs. As a result, a compatibility conflict arises, which may result in error 2003. In order to safely and comfortably update the drivers of all programs and devices on your computer, it is recommended to use the DriverDoc utility developed by Microsoft.
