You should not talk for a long time about the simply incredible prevalence and popularity of devices from Apple. Their gadgets are easy to learn and very beautiful, and only a person who is infinitely remote from computer topics does not know about their reliability.
In particular, the same iPhones are famous for the fact that even the most inexperienced user will quickly and without any effort be able to deal with all their functions. But many users do not know how to reflash the iPhone, and yet such a need may arise for everyone!
For example, not everyone has a normal mobile Internet, and without it it is impossible to update the OS version on the device! And this is not to mention the cases when self-confident users, trying to jailbreak, get a “brick” on their hands.
Update
In all these cases, the process is different. Before flashing the iPhone, we immediately decide: a simple OS update and eliminating the consequences after the intervention of “playful pens” are two different things. Consider the first situation.
So, in this case, you need to connect the smartphone to the computer, launch iTunes and click "Update". Of course, to perform this operation, you must have a normal channel of communication with the Internet.
If you have already downloaded the latest firmware earlier, then when you click the Update button, you must hold down the Shift key (if in Windows) or ALT (OS X). In this case, you can tell the program exactly where the required file is located.
Recovery
We have already talked about how to upgrade your iPhone to a new version of the OS. But much more often a situation arises when things are not all right with the device, and the user wants to "roll back" it to its original state.
All primary actions are no different from the previous version. Thus, you connect the device to a computer running iTunes, but select the “Restore” option. Here again, two options are possible: either the program itself downloads the desired version of the firmware, or you indicate the path to it. Since flashing the iPhone 5 in this way is simple and reliable, we recommend it for beginners.
Sequencing
In the case when the device needs to be restored, the program will automatically perform all the necessary actions. First, the old firmware will be completely removed and Flash overwriting will begin. After the end of the process, the digital signature of the downloaded program will be verified, the smartphone will turn on. After you successfully complete authorization, the system will offer two options:
- Customize as new. In this case, the device will return to its original state. We strongly recommend that you use it if the iPhone has been restored after some serious malfunction.
- Restore from backup. In this case, the previous version of the system will be pumped from the backup. Be careful: if the problem was serious, then with this data it can come back again!
So you have learned how to reflash iPhone in a standard way.
Custom firmware
But the wishes of users are sometimes far more extensive. So, often I want to somehow expand the functionality of the device, without resorting nevertheless to jailbreak. To do this, use the Sn0wbreeze program (for Windows). For the Macs, they use the PwnageTool application. We will not give a detailed description of how to reflash the iPhone 4S in this way. If you have little experience, then there is a good chance that you simply disable your smartphone.
