Then take your phone in hand and deactivate the Find My Phone service by going to the platform settings. Switch off your terminal immediately.
Launch iTunes on your computer and connect the iPhone or iPad to the machine. There, it will be necessary to be as sharp as the silver fox of the desert. You will have to press the power button and the home button for ten seconds . Then, you will have to release the first while keeping the second pressed for three seconds .
iTunes should then launch the special mode dedicated to updating the firmware . If this is not the case, you will have to repeat the previous steps.
Then go to the “Summary” menu and click on the “Restore iPhone” button while holding down the Shift (Windows) or Option (OS X) key. The software will open a window for you to select the firmware to install. Just go find the iOS 8.4.1 file and validate your choice.
iTunes will launch the installation procedure immediately and you will just have to follow the instructions that will appear on the screen.
