Do you remember the problem of our friend Salah El-Din and the technical support experience with Apple (Read the article for more detailsThanks to God, everything is over now and Vodafone Egypt has kindly contacted our brother Salah and replaced the device for him. But the same problem happened with another friend named Ahmed Ayyad, the only difference is that our brother Ahmed is an expert and he never accepts to be challenged by a device ... The problem is that when the iPhone is updated to a new firmware, a message appears

The iPhone could not be restored. An unknown error occurred (-1)

This message, as I told Apple, means a malfunction in the internal parts of the device and that it must be replaced by another, but our expert friend Ahmed was not convinced that there is no solution even if he had to dismantle the device piece by piece :) And thanks to God he succeeded in solving this problem and we would like to warn that this The solution that is unique to the iPhone Islam site is only for experts and specialists in repairing Apple devices, and it is only for error number (1-) We pray to God that you never see it.

Ahmed initially analyzed the modernization process and found that it passes through several stages ...

  • The first stage: Speak when your device is connected to the computer via iTunes, at that time it will inform you that there is a new update for your device's operating system, and when you click to download the update, iTunes connects to Apple's servers and reveals the type and model of your device to download the software that is compatible with it.
  • The second phase: Update after downloading the update to iTunes and start installing the new software on your iOS device.
  • The third step: It is considered part of the download process and begins after the installation of the software is completed on your device when the software is opened and the components of your device are defined to ensure that the hardware and internal components match to work properly with the new operating system.

The problem was facing Ahmed when doing an update to the device every time the installation process reaches 80% stops at this point and the error appears, from here he made many attempts to do the update, but it failed, so Ahmed thought that the failure occurs while identifying the components of the device, so why not try separating all The components of the device and it updates only by connecting the motherboard, so he opened the device and removed the board "motherboard" outside the device and connected it to the USB connection to the computer.

And he successfully restored and did not encounter the error (1-), then he assembled the device again, but after the installation process was completed and the device reached the step of requesting the insertion of the chip to activate it ...

This means that he loaded the entire operating system, and the result was the success of the experiment, and all components of the device worked normally and without any problems after collecting it again.
