Earlier we informed how iPhone is getting bricked if you change the date to January 1, 1970. However, this bricked iPhone can be fixed easily. The only way we knew was to visit Apple Service center, but there is another fix that you can do it yourself.
Fix for the bricked iPhone by date bug
All you need to do is disconnect the battery from the iPhone and connect it again. Unfortunately, iPhones come with in-built battery, so you will need a screw driver to open it. However, you need to be careful while doing this. Once done, your iPhone would be as good it was before, and no data will be lost. If you don’t have an Apple store near you or you don’t have much time to visit the store and get it checked, this is the best solution. However, if you are worried about the warranty stuff or don’t want to do it yourself, then you can visit Apple Store.
