From user experiences it results that the devices Apple they are much more stable and have much fewer errors compared to other manufacturers. Here we refer both to the intended iOS operating system iPhone, iPad si iPod Touch as well as the macOS for Mac si 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 device iPad or iPhone using the appropriate IPSW firmware. If everything goes perfectly, at the end of the process you will have a iPhone with a "new" operating system and with factory settings. However, it is possible that after uploading the IPSW file from iTunes to the device, it will enter an uninterrupted process of scraping. The 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 "boot 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 fix a iPad or iPhone which displays the 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 encountered the error that led to continuous restart following a downgrade process, after resetting the DFU device, it will keep the latest version of iOS. That is, the downgrade will not be done.
Depending on the model iPhone or iPad, entering DFU mode is done differently.
1. online iPhone or iPad la Mac or Windows PC, using a lightning data cable. It is very important to have it installed the latest version of iTunes computer to laptop.
2. Close everything iPhone or iPad. Do this by holding down the “power / sleep” or “power / sleep” + “volume up” button on models iPhone X, iPhone XS, XS Max yes iPhone XR.
3. Once completely closed iPhone or iPad, follow the steps depending on the model of your device.
iPhone 8, iPhone 8 Plus, iPhone X, iPhone XS, iPhone XS Max, iPhone XR: press and hold the Sleep / Power (Side) button 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 need to restart and resume the operation. Release the Side / Sleep button and keep the Volume Down button pressed 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 Sleep and Volume Down buttons simultaneously for approximately 10 seconds. Release the Sleep button, holding down the Volume Down button for another 5 seconds. If the logo appears Apple, resume the operation. If the screen is black, it means that iPhone 7 entered DFU mode.
iPhone 6s or older models: Press and hold the Home and Sleep buttons for 10 seconds, then release the Sleep button and keep Home pressed for another 5 second. The black screen will indicate the device's input to the DFU.
4. Once in DFU mode, in iTunes you will have at hand the options of "Check for updates"And"Restore iPhone"
Wait for iTunes to download the software for your device and start the installation. You will have to be armed with little patience.
At the end you will have a functional device brought to factory settings with a fresh iOS.
