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

As you probably know, all phones sold by Apple are tied to a specific operator. In the US, this is AT & T, in France, Orange, in Germany, T-Mobile and finally O2 in the UK. This is due to the business model of Apple. Under the contract, the operator is obliged to deduct a certain percentage of the income from the subscriber Apple. It is not known for sure how many, but rumor has it 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" iPhone user is as follows:

  • In the company store operator or in the Apple Store phone is bought
  • The subscriber comes home and concludes a contract with the operator via the Internet
  • 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 in the network of any other operator, you need to perform the following steps:

  1. Activate phone
  2. Bypass sim card check

The first step, as expected, is called activation . Its essence is to gain access to the main functions of the device.

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

What is unlock?

Unlock is a modification of the GSM module software that allows you to use an iPhone, like a telephone, with a SIM card of any operator.

There are several methods:

  1. Software (soft unock) - when, without interference with the hardware of the phone, a radio modem is modified, which removes the check that the SIM card belongs to the operator. Usually, the software AnySim (iUnlock) or iPhoneSimFree is used for this. 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 Test Point circuit it gains access to the modification of the program part of the radio modem.
  3. Sim Clone (MultiSIM) - in fact, is not an unlock. This method uses some features of verifying that a SIM card belongs to an operator, through which the phone is "tricked" - the iPhone believes that the SIM card belongs to the AT & T operator. When using this method, the subscriber's SIM card scans the information necessary for authorization in the GSM network of the operator (IMSI, ICCID and secret key Ki) and is recorded on a special smart card that will emulate the SIM. The main problem with this method is that the secret key Ki can be read only from the first generation of SIM cards (SIMv1). Requires special equipment, takes a long time.
  4. Sim Proxy (TurboSIM, StealthSIM, NextSIM, X-SIM and others) is a logical continuation of the SimClone method. Only with the use of hardware "pads" (proxy) between the phone and the SIM card. When the phone asks for information in order to check its belonging to the operator, Sim Proxy gives the AT & T card metric, in other cases it redirects requests to the subscriber's SIM card. It is very easy to use - you simply cut off your SIM card and impose an adapter on it, and then insert this design into the phone. Does not require special equipment.

How is the iPhone?

The phone that you hold (or will hold) in your hands, does not represent anything exclusive in terms of your device as a whole. Its only difference from the class counterparts 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, and in a simplified form I will tell you how it all works, so that the forum does not cause confusion of concepts and any crazy stories.


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

  • ARM processor that controls the operating system
  • Infenion SGOLD2 which is responsible for working with the GSM network (it is called the 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, almost the real MacOS X actually works on your phone), it is responsible for the work 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 (bootloader), flash (firmware) and eeprom (data). 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.


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

On the phone, it all comes with a software package, usually called firmware. This is where the first confusion usually arises, so we will take a closer look at this point.

When enough 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 called the "firmware version of the phone."

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

Now read the previous 2 paragraphs a few more times. Of these, we learned two main terms: the phone firmware and the GSM part firmware. Very much depends on their versions.

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

Bootloader, secpack, OTB, unlock and all

With the release of the update number 1.1.2, one very unpleasant fact was revealed. All phones on sale with this firmware (as they say 1.1.2 out of the box - 1.1.2 out the box, OTB) have a different 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 check algorithm.

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

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

This little nuance ruined the lives of all. Why? Let's now see what software unlock is.

How does unlock work?

In the GSM part of the firmware, there is a check that the SIM card belongs to a specific operator. To be precise, the unique IMSI card code is verified. This code consists of the MCC (Mobile Country Code, country code), MNC (Mobile Network Code, operator code) and subscriber ID MSIN. In the GSM modem, the MCCMNC number is checked, if it is in the allowed table (this list is called the lockstate table), the phone is registered in 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 to find a place in the GSM part of the firmware and modify it in such a way that regardless of the MCCMNC code contained in the ICCID, the check is always successful.

For this, a full copy of the GSM part firmware (dump) is made, which is unloaded and contains the area that needs to be modified, this area is modified. After that, the existing firmware is removed, and the modified one is written back.

Voila, and the phone is unlocked.

It would seem, where does the bootloader?

The key points in the unlock process are erasing the old version and writing the new one. If earlier, this could be done using secpack from the available one, then now it is necessary to have secpack from the next version. Those. Unlock will always be a step later.

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

Yes, by the way, the “good” news: Pioneer of the unlock of the movement Georg Hotz released detailed instructions on how to lower the bootloader version by hardware. Very risky operation, I tell you. On the notorious forum, a huge number of stories about a failed attempt. According to the results of the last vote, every third was unsuccessful.

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

The Shawshank Redemption

Applications. You probably noticed that in the previous paragraphs we talked only about "native" phone applications. As you most likely know, the case was not limited to native applications. Of course, Steve Jobs made it possible to write applications for the phone, but only within the framework of the Safari browser. But this was not enough.

Quickly enough, the iPhone community of hackers found an opportunity to write their own applications for the phone. It took only a few months and the number of applications began to be measured in the hundreds, increasing every day. Today, you probably can't imagine your life without at least a Russian keyboard (Hi, Slavik!). But this is a third-party application.

And the life of third-party applications is impossible without 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" a user in a specific directory when he cannot access everything that is "above" in the file system tree.

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

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

By the way, the de facto standard was the Installer application, the name of which speaks for itself - this is a third-party application installer. Undoubtedly the most popular and sought-after iPhone app ever created outside of Apple.

About the dark past, virgins and bricks

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

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

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

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

Consequently, virginization is needed if and only if the phone has been unlocked by 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 a phone to a specific operator. As a result, there is such a beast in the whole of France as a telephone officially untied from the operator (in Germany, T-Mobile won the court and stopped selling such phones).

But there is a small catch here - these phones can only be used in the country in which the operator is located. Those. If you bought an officially unlocked phone in France, you can choose any french operator for yourself, no more. With SIM cards of operators from another country, such phones will not work!

Error 40265xxxx: errors with numbers 40265xxxx usually occur during the restore phase from the backup after installing iOS on the device. The problem is solved by restoring and setting the device as new. Before setting up as a new device, back up the device backup created by iTunes earlier, for example, copy it to your desktop. For information on where backup files are stored in your operating system, as well as additional notes on how to set up as a new device, see the article “iPhone and iPod touch: backup information”. ITunes backups store SMS messages, various bookmarks, and other program data.

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

2: The firmware is recognized, but cannot be used due to the fact that it is assembled and packaged incorrectly (usually the error appears when working with custom firmware)

four: ?

5: Firmware cannot be installed either due to damage to the boot logos, or due to the fact that the device was entered into the wrong service mode (for example, the firmware is for DFU Mode, and you are trying to recover via the Recovery Mode)

6: Firmware cannot be installed either due to damage to the boot logos, or due to the fact that the device was entered into the wrong service mode (for example, the firmware is designed for DFU Mode, and you are trying to recover via the Recovery Mode)

9: It helps the introduction of the phone in the DFU and restart the computer.

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

13: It 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 Internet connection and try again.

18: ?

nineteen: ?

20: Go to DFU.


23: iTunes cannot read the IMEI or MAC address of the device hardware (the error is often hardware)

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

29: hardware error hardware related to flash memory. - rather Upgrade iTunes to version 10.


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

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


1011: occurs on 2G, and 23 on subsequent models, means BB error, that is, in these cases, you probably do not have everything: IMEI, bluetooth, Wi-Fi, Modem Unknown.

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

1014: Installing a firmware on the phone that does not change the modem, i.e. The firmware gets up normally, but the modem does not correspond to this firmware. You must use the Kick Device Out of Recovery function in the TinyUmbrella utility.

1015: Installing a firmware on the phone that does not change the modem, i.e. The firmware gets up normally, but the modem does not correspond to this firmware. You must use the Kick Device Out of Recovery function in the TinyUmbrella utility.

1600: An error occurs when trying to flash custom firmware on a phone that is not correctly entered into DFU mode. Helps to fix the problem program iReb . With its help, 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: Non-jailbroken device is restored to custom firmware.

1604: Attempt to flash custom on a non-geared phone, make a jailbreak.


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

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






3014: Server problems, download Hotspot Shield and there will be no error.


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

9807: iTunes cannot contact the digital signature verification server. Disable the firewall and antivirus.

9808: Disable certificate checking in Internet settings.
