iOS 10.3 is the last update that came out for Apple's mobile operating system, which brings some new features such as the inclusion of the new HFS + file system and an improvement in overall performance.

Downgrade from iOS 10.3 step by step

It may happen that sometimes a software update does not bring us the improvements that we expected but quite the opposite, hangs, a malfunction in general that forces us to return to previous versions, which is when everything worked by word of mouth. This is something that we cannot rule out in iOS 10.3, and if that is your case, we teach you how to go back to the previous version.

Downgrade from iOS 10.3 in 5 steps

Clarification: First of all, something very important needs to be clarified regarding downgrade on your device. All the data you have stored will be erased, so be sure to back up your data stored in iTunes or iCloud. Once this point is clarified, we can begin.

1. To do this we are going to need iTunes, so if you do not have it installed you can do it from apple.com/itunes. The next and fundamental step, we are going to download the firmware iOS 10.2.1, making sure that we are going to download the one that corresponds to our iPhone or iPad model. (see list below) Let's start iTunes and connect the iPhone or iPad to our computer with a USB cable.

   Make sure you have disabled Find My iPhone on your device. For that we go to Settings> iCloud> Find my iPhone and disable it. Select your device from the upper left corner and then click Restore iPhone while holding down the left SHIFT key (Windows) or the left OPTION key (Mac). In the pop-up window, select the iOS 10.2.1 firmware file that we downloaded in step 2.

iTunes will verify the firmware file and then start the restoration or downgrade process from iOS 10.3 to iOS 10.2.1. I hope it has been useful to you and see you next time.
