What do I need to make my iPhone work with any operator?

As you probably know, all phones sold by Apple are tied to a specific operator. In the US it's AT & T, in France Orange, in Germany T-Mobile and finally O2 in the UK. This is related to the business model of Apple. Under the contract, the operator is required to deduct a certain percentage of the revenue from the subscriber Apple. For certain it is not known how much, but there are rumors that up to 20%.

In this regard, you can use the phone only with the SIM card of the above operators. And nothing else. The scheme for the "legal" user of the iPhone is as follows:

  • In the corporate store of the operator or in the Apple Store, a phone is bought
  • The subscriber comes home and through the Internet signs a contract with the operator
  • After the conclusion of the contract, after a while the phone is activated and it can be used

Therefore, in order for the device to work on the network of any other operator, it is necessary to perform the following actions:

  1. Activate phone
  2. Bypass SIM card validation

The first step, as you might expect, is called activation . Its essence is to gain access to the basic functions of the device.

The second step, called unlocking, in the world - unlock .

What is an unlock?

Unlock is a modification of the GSM-module software that allows you to use your phone as an iPhone, with a SIM card from any operator.

There are several methods:

  1. Soft (soft unock) - when, without intervention in the hardware part of the phone, a radio modem modification takes place, which clears the verification of the SIM card belonging to the operator. Usually, you use the programs AnySim (iUnlock) or iPhoneSimFree. How this process takes place, in detail, you can read in the paragraph: "Bootloader, secpack, OTB and all-all-all."
  2. Hardware (hard unlock) - when the phone is opened and with the help of the closure of the Test Point, access to the modification of the program part of the radio modem is obtained.
  3. Sim Clone (MultiSIM) - in fact, is not "unlocked." This method uses some peculiarities of checking the SIM card's belonging to the operator, by means of which the phone "deceives" - the iPhone considers that the SIM card belongs to the AT & T operator. Using this method, the information required for authorization in the GSM network of the operator (IMSI, ICCID and secret key Ki) is scanned from the subscriber's SIM card and recorded on a special smart card that will emulate the operation of the SIM. The main problem with this method is that the Ki secret key can only be read from the first generation of SIM cards (SIMv1). It requires special equipment, it takes a long time.
  4. Sim Proxy (TurboSIM, StealthSIM, NextSIM, X-SIM and others) is a logical extension of the SimClone method. Only with the use of hardware "pads" (proxy) between the phone and the SIM card. When the phone requests information in order to check its belonging to the operator, Sim Proxy gives the metric of the AT & T card, otherwise redirects requests to the subscriber's SIM card. Very easy to use - you just cut your SIM card and put an adapter on it, then insert this design into the phone. Does not require special equipment.

How is the iPhone?

The phone you hold (or will keep) in your hands, nothing exclusive in terms of its device as a whole does not represent. The only difference from its counterparts in the class is the lack of a keyboard and a display that recognizes two touch points at the same time.

I will not give a specific list of "hardware", which is located in the phone, but in a simplified form I will tell how it works, so that the forum does not cause confusion of concepts and all delusional stories.


At the level of iron, it is important to know that the phone actually has two processors:

  • The ARM processor that manages the operating system
  • Infenion SGOLD2 which is responsible for working with GSM network (it is called radio modem, baseband, gsm-modem, bb).

The first processor (we will call it CPU) is actually the heart of the phone: it is responsible for the operation of the operating system (by the way, on your phone and in fact the real MacOS X works), it is responsible for the operation of absolutely all of your applications.

The second processor (we will call it baseband, abbreviated BB), is responsible for the communication capabilities of the phone: GSM, EDGE / GPRS, WiFi and Bluetooth. Like the CPU, it also has some sort of operating system, which consists of several components: boot loader , flash and eeprom . All this stuff is stored on a special memory module (Intel Wireless Flash Memory, a separate chip on the board), it is also called NOR flash.


But now let's talk about more close to us things - software. If you look at the previous section, it becomes clear that the phone has two types of programs: for CPU and for BB.

In the phone, it all comes with a software package, usually called firmware. Here, usually, the first confusion arises, so we will consider this point in more detail.

When a sufficient number of fixes are collected, Apple releases an update - an IPSW file of about 150 megabytes in size, containing an image of the phone's operating system and sometimes an update for the GSM part. Therefore, in one update there can be two "firmware": for the software part of the phone (application update) and for the GSM part.

This package has its own version (1.0.0, 1.1.1, 1.1.2, etc.), but the GSM part has its own numbering (03.01_13G, 04.02_13G, etc.). It turned out that the programs installed in the phone itself are characterized by the version of the update package, for example the latter has version 1.1.3. This is commonly called the "firmware version of the phone."

It so happened that you can install any of the existing updates on your phone, but the firmware version of the GSM part will not change. You can have the firmware of GSM-part for version 04.03_13G and firmware of phone 1.0.2.

Now a few more times, read the previous 2 paragraphs. Of these, we have borne two basic terms: the firmware of the phone and the firmware of the GSM part. A lot depends on their versions.

But in the light of recent events, another term appears on the stage: the bootloader version. This issue deserves a separate discussion.

Bootloader, secpack, OTB, unlock and all-all-all

With the release of the update for the number 1.1.2, one very unpleasant fact was revealed. All phones that came on sale with this firmware (as they say 1.1.2 out of the box - 1.1.2 out the box, OTB) are different from the previous bootloader. The version of the new loader is 4.6, whereas the previous one had version 3.9.

In this version, Apple fixed many vulnerabilities and changed the secpack verification algorithm.

Secpack - the area in the update package that contains digital signatures to a particular firmware version of the GSM part of the phone. Required to modify the GSM-modem software.

If in the bootloader version 3.9 it was possible to perform operations with the GSM part having secpack from the current or next version of the firmware (> =), then in the bootloader 4.6 such operations are possible only with secpack from the next firmware version (>). Plus everything else, the entry into the area in which the bootloader is located, after its initialization became impossible, which makes it a "rollback" impossible.

This little nuance spoiled life for everyone. Why? Now let's see what software unlock is.

How does unlock work?

In the firmware of the GSM part, there is a check for the belonging of the SIM card to a particular operator. To be precise, the unique IMSI card code is checked. This code consists of MCC (Mobile Country Code, country code), MNC (Mobile Network Code, operator code) and MSIN subscriber ID. In the GSM modem, the MCCMNC number is checked, if it is in the resolved table (this list is called the lockstate table), the phone registers with the operator's network, if not, the GSM part is blocked.

Accordingly, to use the phone with any operator, this check must be bypassed. The only method is to find a place in the firmware of the GSM part and modify it in such a way that, regardless of what MCCMNC code is contained in the ICCID, the check is always successful.

For this, a complete copy of the firmware of the GSM part (dump) is made, which is unloaded and there is an area in it that needs to be modified, this area is modified. After that, the existing firmware is deleted, and the modified firmware is written back.

Voila, and the phone is broken.

It would seem, where does the bootloader?

The key points in the unlock process are the erasing of the old version and the recording of the new one. If earlier, you could do this using secpack from available, now you need to have secpack from the next version. Those. unlock will always be one step later.

By the way, another obvious blow: updating the firmware of the modem makes its unlock impossible. Those. if you had a working 1.1.2, and suddenly updated to 1.1.3, to call you will have to wait until the next update containing a GSM modem update is released.

Yes, by the way, "good" news: Pioneer unlock motion Georg Hotz has issued a detailed instruction on how to downgrade the bootloader's hardware version. Very risky operation, I tell you. At the well-known forum, a huge amount of stories about an unsuccessful attempt. According to the results of the last vote, one in three was not successful.

Well, well, the educational program on the basic concepts can be considered complete. It remains to highlight a few more points.

The Shawshank Redemption

Applications. Perhaps you noticed that in the previous paragraphs we only talked about "native" phone applications. As you probably know, the native applications did not stop there. Of course, Steve Jobs gave the opportunity to write applications for the phone, but only within the browser Safari. But this was not enough.

Quite quickly the community of iPhone hackers found the opportunity to write their own applications for the phone. Only a few months passed and the number of applications began to be measured in hundreds, increasing with each passing day. Today, you probably do not imagine your life at least without a Russian keyboard (Hello, Slavik!). But this is a third-party application.

And the life of third-party applications is impossible without a jailbreak

Jailbreak (literally "jailbreak") - the process of obtaining full access to the file system of the phone. The concept of jail came to us from the depths of the * nix community and means "locking" the user in a certain directory, when he can not access everything that is located "above" in the tree of the file system.

Initially, the user has write access only to the / var / root / directory (where all the settings and media content of the user are stored) on the phone. All anything, but only for the sake of everything else, in this directory it is forbidden to run applications.

Jailbreak allows you to have full access to all the folders and files on your phone (read, write and execute). Now, with the release of each update, all users (including "legal") follow the news and wait for the jailbreak to become possible.

By the way, the de-facto standard was the Installer application, whose name speaks for itself - it's the installer of third-party applications. Undoubtedly the most popular and demanded application for the iPhone, ever created outside of Apple.

About the dark past, virgins and bricks

Many remember the times of the first phones, when unlock took 40 minutes, during which we watched the running lines in the terminal. Then the air was cleaner and the grass was greener.

As a gift from these times, we got the term virgininization. There was all this from where: the old versions of AnySim (iUnlock), by mistake removed from the firmware of GSM-part a small area - seczone. In this area, a table with a list of "allowed" MCCMNC codes and a unique key for each key were stored.

As it turned out, when upgrading from 1.0.2 to 1.1.1, the phone stopped accepting even the native AT & T sim card, turning into a beautiful brick. The explanation is simple: when updating the firmware, the area in which seczone is stored is not updated. Therefore, the firmware tries to check the presence of MCCMNC in a table that does not exist.

Then the concept of virginization appeared. Speaking in Russian: bringing the phone into a virgin state, when the original version of the firmware is returned (without unlock) and lockstate is restored in the secon.

Therefore, the virginization is necessary if and only if the phone is unlocked by the old versions of AnySim (up to 1.1) and iUlock.

About officially unlocked phones

As you know, European legislation does not look very well at the idea of ​​linking the phone to a specific operator. As a consequence, already in the whole of France there is such a beast as an officially unconnected phone from the operator (in Germany T-Mobile won the court and stopped selling such phones).

But there is a small catch - these phones can only be used in the country where the operator is located. Those. if you bought an officially unlocked phone in France, you can choose any French operator, no more. With SIM cards from other countries, such phones will not work!

ITunes backups store SMS messages, various bookmarks and other program data.

As you all see a large number of "ifs" or "either", and each error needs its own approach and its solution! Having rummaged, I found several solutions to problems with errors, and I need your help with closing the "Black Holes" in this list:

2: The firmware is recognized, but can not be used because it is collected and packaged incorrectly (usually a bug appears when working with custom firmware)

4: ?

5: The firmware can not be installed either due to damage to the boot logos, or because the device is not entered into the service mode (for example, the firmware is for DFU Mode, and you are trying to restore through Recovery Mode)

6: The firmware can not be installed either due to damage to the boot logos, or because the device is not entered into the service mode (for example, the firmware is for DFU Mode, and you are trying to recover through Recovery Mode)

9: Helps you insert the phone into DFU and restart the computer.

10: The low-level LLB loader is corrupted or missing due to the crookedly assembled custom firmware-Download another custom firmware or rebuild it yourself.

13: Helps to disable the protection of the computer (firewall, antivirus) .- either the problem of a USB cable or a 30-pin connector or an attempt to install a beta version of iOS from under Windows.

14: You downloaded the broken firmware file, establish a normal connection to the Internet and try again.

18: ?

19: ?

20: Go to the DFU.


23: iTunes can not read the IMEI or MAC address of the device's hardware (the error often has an attachment character)

28: Hardware failure of the 30-pin connector, go to the service.

29: The hardware error of the device is associated with the flash memory. - rather Update iTunes to version 10.


50: Update iTunes to the latest version, log out and log in again, disable the firewall and antivirus.

1004: - Itunes error, with the modified hosts file. Suppose there are registered addresses of Saurik. If all the lines are replaced by a # sign, then there will be no error, but the SHSH files will be taken directly from the Apple servers, and therefore only for the latest firmware.


1011: occurs on 2G, and 23 on subsequent models, mean BB error. That is, in these cases, most likely you do not have: IMEI, bluetooth, Wi-Fi, Modem Unknown.

1013: The firmware version is too low (you tried to roll back the modem, which is almost impossible). Poke on a later version of the firmware.

1014: installation of firmware on the phone, which does not change the modem, i.e. firmware rises normally, but the modem of this firmware does not match. You need to use the Kick Device Out of Recovery feature in the TinyUmbrella utility.

1015: installation on the phone firmware, not modifying the modem, i.e. firmware rises normally, but the modem of this firmware does not match. You need to use the Kick Device Out of Recovery feature in the TinyUmbrella utility.

1600: An error occurs when trying to flash a custom firmware on a phone that is not correctly inserted into DFU mode. The iReb program helps to fix the problem. With it, enter the device in DFU mode and then select the desired custom firmware in iTunes.

1601: Change the USB port, or try on another computer.


1603: A non-jailbreak device is restored to the custom firmware.

1604: Trying to flash a custom on a non-jail phone, do a jailbreak.


1609: The iTunes version is too old to work with the device.

1611: Change the USB port, or try on another computer.






3014: Problems with the server, download Hotspot Shield and there will be no error.


3194: It is not possible to request a suitable SHSH hash from the firmware signing server. Occurs if you redirected iTunes to the Cydia server via the hosts file or TinyUmbrella utility, but there are no saved hashes on the server for this firmware. Decision- if you do not have SHSH then you need to flash for the most recent off. firmware.

9807: iTunes can not contact the digital signature verification server, Turn off the firewall and antivirus.

9808: Disable certificate verification in the Internet settings.
