From user experiences it results that the devices Apple they are much more stable and have much fewer errors compared to those of other manufacturers. Here we refer both to the iOS operating system intended for iPhone, iPad and iPod Touch and to macOS for Mac and Macbook.
But there are situations when these are also unpleasant surprises. One of the most common is restarting continues (loop restarting) after one is done upgrade or downgrade of iOS with the help iTunes and files IPSW containing firmwareof the device.
In this tutorial I showed you how can i install iOS for your iPad or iPhone device using the appropriate firmware IPSW. If everything goes perfectly, at the end of the process you will have an iPhone with a "new" operating system and with factory settings. However, it is possible that after uploading the file IPSW from iTunes on the device, it will enter an uninterrupted process of restorations. Logo appears Apple, but does not show that something is loading. After a few minutes it will restart and do the same thing indefinitely. This anomaly is known as “reboot loop" or "boat loop" blod.
Even if your device no longer listens to any commands and there seems to be nothing to do with these endless reboots, you should not panic. Apple has thought of all possible error scenarios on devices and offers simple solutions. You just need a little attention.
How can we repair an iPad or an iPhone that displays a logo Apple continuously and restarts itself
The only solution to stop the infinite restarts and not to have the logo appear Apple endlessly, is to put the device in DFU mode (Device Firmware Update) and make a total resettlement.
If you enterpinand the error that led to the continuous restart following a downgrade process, after resetting the DFU the device will keep the latest version of iOS. That is, there will be no downgrade.
Depending on the iPhone or iPad model, entering DFU mode is done differently.
1. Connect your iPhone or iPad la Mac or Windows PC, using a data cable lightning original. It is very important to have it installed the latest version of iTunes computer to laptop.
2. Close your iPhone or iPad completely. Do this by holding the "power / sleep” pressed or “power / sleep” + “volume up” in the case of iPhone X, iPhone XS, XS Max and iPhone XR models.
3. Once the iPhone or iPad is closed, follow the steps according to the model of your device.
iPhone 8, iPhone 8 Plus, iPhone X, iPhone XS, iPhone XS Max, iPhone XR: press and hold the button Sleep/Power (Side) for 3 seconds, then press and hold the Volume Down button. Hold down the two buttons (Side and Volume Down) for 10 seconds. If the logo appears Apple, you will have to restart and resume the operation. Release the Side/Sleep and keep pressing the Volume Down button for another 5 seconds. If the screen remains black and nothing is displayed on it, it means that the device has entered DFU mode. You are on the right track.
iPhone 7 and iPhone 7 Plus: press and hold the buttons simultaneously Sleep and Volume Down for about 10 seconds. Release the button Sleep, keeping the Volume Down button pressed for another 5 seconds. If the logo appears Apple, resume the operation. If the screen is black, it means that the iPhone 7 has entered DFU mode.
iPhone 6s or older models: press and hold the buttons Home si Sleep for 10 seconds, then release the button Sleep and keep Home pressed for another 5 seconds. The black screen will indicate the entry of the device in DFU.
4. Once entered DFU mode, in iTunes you will have the options of "Check for updates"And"Restore iPhone"
Expect that iTunes to download the software for your device and start the installation. You will have to arm yourself with a little patience.
At the end, you will have a functional device brought to factory settings with a fresh iOS.
