It is not good for the owner of such an expensive and exclusive device to run to the service center whenever there are difficulties in the operation of the iOS device at the software level or Apple presented new version mobile operating system iOS. Moreover, the process itself takes no more than 10 minutes and the user, in most cases, requires a minimum of effort.
We will consider the subject of today's instructions using the iPhone as an example, so it will be easier for us and for you, dear readers.
What is iPhone Firmware?
If we are talking about the firmware of an iOS device as a software component, the iPhone firmware is its software or operating system. AT Apple iphone software, iPod Touch and iPad are called iOS for short, which means iPhone Operation System in English.
If we talk about flashing an iOS device as a process, flashing an iPhone is a process of restoring or updating software devices. The most commonly used term is "flashing".
iPhone flashing options
Flashing an iOS device includes 2 processes at once:
- recovery;
- update.
At its core, the processes are identical, that in the first, that in the second case, as a result of flashing on the iPhone, new iOS. Moreover, the concept of “new” in the case of restoring the iPhone does not refer to the version of the operating system, but to its state, in other words, “clean”.
iPhone Flashing Methods
You can reflash iPhone in 2 ways, one of them is universal, i.e. is used for both recovery and update, the second is only for updating:
- iPhone firmware via iTunes;
In the first case, the software is downloaded to the computer and, using the iTunes media combine, it is downloaded directly to the iOS device. Relevant for iOS 4.3.5 inclusive. For iOS 5 and above, the second method is possible, which involves updating iOS directly from the device via the Internet via wireless network(wi-fi).
What is the difference between restoring an iPhone and updating it?
As we have already said, restoring or updating an iPhone refers specifically to the software component of the device.
iPhone recovery is a recovery process initial settings devices. When restoring, all content (photos, videos, music) and personal data (phone book, calendar information) will be deleted from the iPhone, the device settings will be reset to factory settings.
In a nutshell, restoring an iPhone is resetting the device to the factory state and installing a “clean” iOS of the latest version.
An iPhone upgrade refers to the process of moving from a more old version iOS to a newer one. As a result of the update, all content, personal data and settings will remain intact and iOS will be updated to the new version.
As you can see, the fundamental difference between restoring and updating an iPhone is that as a result of the update, content and personal data are not deleted from the Phone.
The result is:
iPhone Recovery = Delete Content + Factory Reset + iOS Update
As you know, the iPhone, like any other iOS device, can be in several modes provided by the manufacturer: normal mode, ( recovery mode) and (DFU Mode).
It is possible to restore or update an iPhone in the following modes:
- in normal mode;
- in Recovery Mode;
- in DFU mode.

Is it possible to reset iPhone without updating iOS?
If we are talking about a “clean” iPhone restore via iTunes, as a result, the device will have the latest version of iOS installed, i.e. in fact, a firmware update will occur, and this is far from always necessary, especially for owners of jailbroken devices. Why? Because the jailbreak for the current iPhone firmware version appears, as a rule, with a big delay, and as a result, updating the iPhone will entail the loss of the jailbreak.
Restoring/Updating a "locked" (blocked for a specific operator cellular communication) A jailbroken iPhone entails:
- blocking a "locked" iPhone - you will not be able to connect the device to the cellular network of another operator;
- jailbreak loss.
Fortunately, there is a way to remove all content from it without updating the iOS version and without losing the jailbreak. We have already talked about the SemiRestore utility, which allows you to clear the contents of an iOS device and reset its settings to factory settings without loss. Take advantage if you have a “locked” or “jailbroken” device on your hands.
iPhone update
We have already mentioned that there are 2 ways iOS updates-device on latest version iOS:
- With connection to a computer via iTunes;
- Directly from an iOS device via Wi-Fi.
The first method is practically the same as restoring an iPhone to current version firmware. The second allows you to update your iPhone to the latest iOS without connecting to a computer via Wi-Fi.
Update iPhone from Computer via iTunes
1. Connect your iPhone to your computer with a USB cable and launch iTunes. Go to the "Devices" menu and select your device;
Selecting a device in iTunes
2. On the iTunes sync settings and device connection settings page, left-click on " Refresh". Confirm iPhone update to the latest version of iOS.
3. You can save time and not wait for iOS to download service folder iTunes after downloading the latest iOS to your hard drive. With the combination " Shift+Refresh» Initiate the firmware update from the hard drive.
After the update, you will receive an iPhone with the latest iOS "on board", all user content and settings will be saved.
Update iPhone over Wi-Fi
With the advent of iOS 5.0, developers have integrated the ability to update the firmware directly into the mobile operating system. Starting with iOS 5.0 and higher, the "Software Update" menu item is available in the settings of iOS devices. The update is available only when connected to the Internet via Wi-Fi. Bandwidth internet connection cellular networks does not allow you to update iOS over 2G or 3G connection.
1. On iPhone go to Settings – Main – Software Update;
Switch to software update in iPhone settings
2. Tap on " Download and install» and in the next window, accept the terms of use. Wait until the end of the process.
This is what an iPhone update via WiFi looks like
Let us remind you once again that updating iOS does not entail the loss of user data and content and resetting settings, but it is dangerous for jailbroken and locked devices.

More recently, the famous Canadian iOS programmer, known under the nickname iH8Sn0w until version 2.9.9. This application will be very useful for owners of Apple smartphones locked to the operator, because. only with the help you can get it on iPhone 4 and iPhone 3GS with subsequent unlocking.
Main Feature This tool is to create a custom firmware iOS 6.1 with a jailbreak without modem upgrade and with the possibility of activation (hacktivation).
The disadvantages include working only in the operating room Windows system and only support for older devices such as iPhone 3GS and iPhone 4.
What is custom firmware for without modem upgrade?
The fact is that when updating (restoring) iPhone 3GS or iPhone 4 (and any other iPhone) on official firmware, along with updating iOS itself, the version of the modem firmware, which is responsible for unlocking the smartphone, is often updated.
For example, if you have an iPhone 3GS locked to the operator with the legendary modem version from the iPad - 06.15.00 (or any other), then when you update to the official iOS 6.1 firmware, at best you will receive a “software” (correctable) brick, but if If your iPhone 3GS was released after October 2011, then there is a huge chance of getting a “hardware” brick, which can only be restored by replacing the so-called modem part of the “flash drive”. The pleasure is not cheap, the cost of replacing a "flash drive" is from $30 to $80.
From my own observations, I can say with 99.9% certainty that you will not “catch” a hardware failure of the modem part (flash drive) on an iPhone 3GS with 16 or 32 GB of memory. These models ceased production until October 2011. But, with the iPhone 3GS 8 GB version, you need to be more careful, I repeat that when updating the iPhone 3GS 8 GB, released after October 2011 to the official firmware, there is a huge probability of failure of the modem part of the smartphone.
The first signs of failure of the modem part are the absence of Settings values IMEI, Bluetooth, WiFi. If the problem is caused by an update (recovery) to the official firmware, then on the iPhone 3GS 16 and 32GB it can be cured programmatically, but not always on the iPhone 3GS 8GB. I take this opportunity to invite (pah-pah-pah, of course) to our "Apple-repair" — .
And so, the custom iOS 6.1 firmware obtained with the help provides an opportunity to restore any iPhone 3GS or iPhone 4 locked to the operator WITHOUT updating (upgrading) the modem firmware version. Those. in this case, ONLY the iOS version is upgraded, and the modem version remains unchanged. This allows you to easily unlock iPhone 3GS or iPhone 4 on iOS 6.1 firmware using a utility or turbo SIM cards (Gevey, Rebel, etc.)
