Apple's iPhone has been jailbroken. When you jailbreak your iPhone SE, your chances of experiencing the same issue increase. For starters, jailbreaking is the act of eliminating software limitations placed on Apple's mobile operating system by the company. Jailbreaking your iPhone SE, for example, grants you root access to the iOS file system, allowing you to install applications, extensions, and themes that aren't accessible through the Apple App Store. It is completely legal to break into a prison, but it is not advised. Why? Because, while it has some potential benefits for the consumer, it also has significant drawbacks. One of them is your iPhone becoming stuck on the Apple logo.

Hardware issues.

This is the most serious of the possible causes. Because of a broken hardware component, an iPhone SE may not be able to get beyond the Apple logo in some situations. This is most likely the situation if your iPhone was previously dropped or wet and a component was damaged as a result of the occurrence. Each iPhone component has a particular duty assigned to it. Unfortunately, if this happens to your iPhone, the only way to have it fixed is to get it diagnosed by a specialist for possible repair. This also implies that you will be required to pay for an essential service.

Solution

Disable third-party security software for the time being.

If your iPhone SE is stuck on the Apple logo after you've synced it to a computer, it's possible that an application, particularly a security utility installed on your computer, is preventing the syncing process. For example, your iPhone may become stuck on the same screen when you use iTunes to update, restore, or transfer files from your computer to your iPhone. Some security software may intervene and disrupt the data transfer, prompting iTunes to cancel it. As a consequence, your iPhone is only partially updated/restored and hence useless. In such circumstances, your iPhone will normally enter recovery mode and request you to connect to iTunes, although it may become stuck on the Apple logo in some cases. When you try to sync, update, back up, or restore your iPhone, you can see a numeric error message.iTunes Errors 4, 6, 1630–1641, 3000–3999, or 9000–9999 are among the error numbers that indicate a security software issue. If any of these error codes appear on your device, look for any installed third-party security software and try disabling it momentarily to see what happens.
