Generate an unlock code 3.1 from IMEI. Five Best Android SIM Unlock Code Generator Reviews. Method - Online Calculator

Unfortunately, you encountered the so-called "locked" phone. This means that it is blocked under a specific operator mobile communications And with another will not work. Such phones are usually sold in branded salons of operators and cost cheaper than unlocked versions.

If you insert a single operator's SIM card, the phone when enabled will ask you to enter a "pin network unlock code for a SIM card":

Or give an error with the text "Incorrect SIM card (an SIM card with a blocked network is inserted)":

Blackbury SUT 100-01, requires PIN code to unlock the network.

Often "locked" phones are involved in a variety promotional promotionsAnd on their blocking attention is not accentuated. This is done so that you continue to use only this particular telecom operator. In this article, consider solving your problem.

Transition to another operator

You can easily bypass blocking, simply transferred your number to the desired operator. It will take about a week and will cost 100 rubles. To do this, you need to contact any office of that operator to which you want to translate the room. You can read in detail about the procedure for changing the operator.

Unlock (unlok, unlock) phone

You need to find an instruction on the Internet and program to select your code to your phone. It may be necessary to flash and. If you can not find information on your own - write in the comments model of your phone, we will help you.

Appeal to the service center

You will take a decent amount for unlocking in the service, but sometimes there are simply no other options.

In this article we will tell you about how to unlock almost any 3G modem Huawei, without possessing any special knowledge or skills. We have already talked about our service to unlock Huawei modems, which allows you to generate unlock codes (NCK codes) for 3G huawei modems According to the old and new algorithm, here we will end in more detail on its use.

Almost any cellular operator blocks its modems, without allowing you to use the SIM card of another operator. What is generally obvious, because Often in operators cellular communication Special conditions and stocks operate, thanks to which the modem can be sold with a significant discount, implying that and in the future it will be used only with SIM cards this operator. Modem lock under a specific operator (the so-called simlock) is a standard function laid by a modem manufacturer, however most modems support and reverse function, i.e. Unlock. When installing a SIM card of another operator and start a program to connect to the Internet that came with the modem, a window appears, offering entering an eight-digit code. This code is called unlock code, or NCK, Unlock code. After entering this code, the lock on the operator is removed and the modem begins to "understand" any SIM cards. Let's figure out how you can get the unlock code for the Huawei modem.

The first thing to do is find out the IMEI of your modem. IMEI - International mobile equipment identifier, unique for each device that uses its device is a 15-digit number. You can see it next to serial number Modem on the housing or under the lid closing the SIM card. For example, for the Huawei E173 modem from megaphone, it is located here:

Or learn software using any terminal program. To do this, you need to connect your modem to the computer, go to the Device Manager -\u003e Modems. Find there huawei device Mobile Connect - 3G Modem and in the properties on the Modem tab to determine the COM port, which is used by the modem:

In our case, this is COM9. After that, open any terminal program, for example, Hyper Terminal (standard terminal program, which is part of Windows 95, 98, ME, XP), Putty or My Huawei Terminal. We will consider connecting to the modem on the example of PUTTY. The first thing we will do is turn on in the terminal emulator settings of the local echo mode, so that we have seen the commands by us:

Then connect to the modem:

And enter the team ATI:

If we did everything correctly, we will get an answer from the modem containing our IMEI (as in the figure above). In this case, we determined that our IMEI - 863448016071935.

For iMEI definitions You can use or more simple way, download from the official site last version DC Unlocker Client, Run it and click the Find button:

When your modem is determined, in the window below we will see IMEI modem, as well as additional information. In particular, we see that voice functions in this modem are blocked (Voice Feature: Disabled), the modem itself is blocked on the operator ( SIM Lock. Status: Locked) and the remaining number of unlock code input (Unlock Attempts Left: 10). In order for the user to not enter the code for a simple bust, the manufacturer entered the restriction, the default is available 10 attempts to enter the unlock code, each time you enter the unlock code incorrectly, the number of these attempts is reduced by one. If you have 0 attempts to enter unlock code - this modem is unlocked by simply entering the code will not be possible, be careful!

We now turn to receiving the unlock code. Here it is necessary to make a reservation that they are two "types". Unlock code according to the old algorithm (Old Algo Unlock Code) and unlock code for a new algorithm (New Algo Unlock Code). This is due to the fact that for old modem models (old versions of the firmware) codes were calculated on the old algorithm, for new modems (modems with new version Firmware) - in a new one. Here is a small list of conformity:

• Old Algo Unlock Code - E150, E1550, E155, E156, E156G, E160, E160G, E161, E166, E169, E169G, E170, E172, E176, E180, E182E, E196, E226, E270, E271, E272, E510, E612, E618, E620 , E630, E630 +, E660, E660A, E800, E870, E880, EG162, EG162G, EG602, EG602G, Vodafone K2540, Vodafone K3515, Vodafone K3520, Vodafone K3565, Vodafone K3715, etc. These are modems with the old algorithm.
• NEW ALGO UNLOCK CODE - E137, E171, E173CS-1, E1732, E173, E1815, E272, E303, E303 Hilink, 320s (E3121), E3131 (420D), E3276, E352, E353, E355, E357, E362, E363, E367, E368, E369, E372, E392, E397, E398, E586, E5776 (821ft), E5776S-22, E589, E589U-12, etc.

To get the unlock code for your modem, click on the link - unlocking Huawei modems and enter your IMEI in the 15 Digit IMEI field. note that get free unlock code for a new algorithm this service allows only from 12:00 to 14:00 (GMT + 4), at all other time instead of the unlock code for a new algorithm you will be issued a link to the trading platform, where inserting your IMEI you can purchase this code for the symbolic amount that will go to Project authors support fund. If you have come to service from 12:00 to 14:00 in Moscow, then the status of the server will be displayed as free, at everything else, like PAID:

We enter our IMEI and press the Calculate button, in response, we get approximately the following:

As you can see, an unlock code is present in the server's response to a new and old algorithm, Flash Code (code required for flashing modem) and Reset Counter Hash (reset code attempts to enter unlock codes, relevant only for old modems). In our modem Huawei E173 unlock code obtained according to a new algorithm, i.e. 82828335. Insert the SIM card of the other cellular operator (In our example, not MegaFon), launch the built-in connection program from the Internet, to invite to enter the unlock code - enter the NCK code received by us. Voila, modem unlocked. If the invitation to enter the code did not appear, we enter the command in the terminal program AT ^ cardlock \u003d "NCK Code" where NCK Code - the unlock code received. Those. For our example, we must enter AT ^ cardlock \u003d "82828335 " (Enter this command should also enter how we entered the ATI command to determine the IMEI modem).

If you used the DC-Unlocker Client to determine IMEI, you can enter the unlock code in it, simply by typing the unlock command in the command input window:

We remind you that the AT command with the unlock code is necessary without a sim card or with a "non-" sim card (another operator). After that, your modem is unlocked.

Also, with the help of AT commands, you can check the status of blocking your modem and the number of remaining attempts to enter the unlock code:

AT ^ Cardlock? - Checking the status of blocking and the remaining attempts to enter the unlock code. In response, the modem will give a cardlock: a, b, 0, where A is the state of blocking, B is the number of remaining unlock attempts. A \u003d 2 means that there is no symple, a \u003d 1 if the modem is locked.

If you for some reason, you can not use the Huawei modem unlock service free time, you can purchase the Huawei unlock code on trading platform. Sale code takes place online, without the participation of the operator. Immediately after entering IMEI and making payment (trading placeplac of Plati.ru supports many payment systems, payment from the balance cell phone Through SMS and MN. Another) You will receive the code you purchased (code is displayed instantly in the "Paid product" window). Be careful when entering IMEI.

In this article we will try to a little one to open the veins of secrecy over Huawei and Alcatel unlock algorithms. All know that manufacturers data devices are unlocked by code, but how is it calculated and where does the unlock code come from?

In our article about we wrote that unlock codemaybe a function from Imei phone (and, thus, it can be calculated) or it is tightly sewn in a flash chip phone (and then it will be recognized only through the internal database of the manufacturer). Let's look at the Huawei modem models with the old algorithm that we wrote about before. As we said, the unlock code for them can be calculated by a special calculator, but how is this calculator inside?

Naturally, the manufacturer carefully hides the opening codes generation algorithm (in the case of Huawei modem with an old algorithm, Old Algo, unlock code is a function of IMEI, i.e. NCK \u003d F (IMEI)), But in this case, the algorithm has already managed to consult a network and in this article we will consider it. I repeat that everything described only applies to models E150, E1550, E155, E156, E156G, E160, E160G, E161, E166, E169, E169G, E170, E172, E176, E180, E182E, E196, E226, E270, E271, E272 , E510, E612, E618, E620, E630, E630 +, E620, E660A, E800, E870, E880, EG162, EG162G, EG602, EG602G, Vodafone K2540, Vodafone K3515, Vodafone K3520, Vodafone K3565, Vodafone K3715 and others.

Algorithm of the NCK generator codes for Huawei

The source code of the php algorithm looks like in the following way:

Huawei Algo PHP Source Function Calcoldnck ($ IMEI, $ Secret \u003d "HWE620DATACARD") ($ Magic \u003d Substr (MD5 ($ Secret), 8,16); $ n \u003d str_split (MD5 ($ IMEI. $ Magic), 2) ; foreach ($ n AS & $ V) ($ V \u003d hexdec ($ V);) $ n1 \u003d $ n ^ $ n ^ $ n ^ $ n; $ n2 \u003d $ n ^ $ n ^ $ n ^ $ n ; $ n3 \u003d $ n ^ $ n ^ $ n ^ $ n; $ n4 \u003d $ n ^ $ n ^ $ n ^ $ n; $ s \u003d sprintf ("% 02S", DeChex ($ n1)). Sprintf ( "% 02S", DeChex ($ n2)). Sprintf ("% 02S", DeChex ($ n3)). Sprintf ("% 02S", DeChex ($ N4)); $ n \u003d sprintf ("% d", (Hexdec ($ s) | 0x2000000) & 0x3FFFFFF); RETURN $ n;)

1. Here, at the input of the CalcoldnCK function - $ IMEI is a line with the IMEI device, and $ secret is a secret constant equal to HWE620DATACARD.
2. As we see, the MD5 is considered to be MD5 from $ secret, which is equal to "A32FE72C 5E8DD316726B0335d5513BA0, then selected 16 characters are taken from it. This will be $ magic.
3. Then we consider MD5 hash from IMEI and the $ Magic constant received. Suppose that IMEI we have 860650020246212, then the IMEI and $ Magic combination - will give us a line "8606500202462125e8dd316726b0335", and MD5 hash from it, respectively, "9423F197Fe0547CF7A".
4. We divide this line to bytes in a hexadecimal representation, i.e. 0x94, 0x23, 0xF1, etc.
5. As a result, we obtain an array:

   Array.
   => 148
   => 35
   => 241
   => 151
   => 250
   => 250
   => 212
   => 136
   => 126
   => 225
   => 105
   => 254
   => 5
   => 71
   => 207
   => 122
   )

6. As can be seen, the zero element of the array is 0x94 (148 in decimal representation), the first - 0x23 (35), and the like.
7. Next, we consider the number N1, N2, N3, N4 (in fact, these are bytes of the future NCK) by formulas:

   $ n1 \u003d $ n ^ $ n ^ $ n ^ $ n;
   $ n2 \u003d $ n ^ $ n ^ $ n ^ $ n;
   $ n3 \u003d $ n ^ $ n ^ $ n ^ $ n;
   $ n4 \u003d $ n ^ $ n ^ $ n ^ $ n;

8. Where ^ - This is the operation "excluding or", i.e. Xor.
9. Thus we get:

   N1 \u003d 148 XOR 250 XOR 126 XOR 5 \u003d 21
   N2 \u003d 35 XOR 250 XOR 225 XOR 71 \u003d 127
   N3 \u003d 241 XOR 212 XOR 105 XOR 207 \u003d 131
   N4 \u003d 151 XOR 136 XOR 254 XOR 122 \u003d 155

10. Or in a hexadecimal system (N1, N2, N3, N4) \u003d (15.7F, 83,9B). We combine these numbers, and we get a hexadecimal number - 157F839B (360678299).
11. And we had the last step, namely, to get NCK, we perform the following transformation over it - 0x157F839b.oR 0x2000000 and 0x3FFFFFF. It can be done using standard windows Calculator, switting it in the type of programmer.
12. As a result of this operation we get 0x37F839B.. Translating it to B. decimal system Nacking, get the desired NCK (unlock code) - 58688411 .

Check the resulting result by any publicly available Huawei calculator and make sure that we got the right result:

At the beginning of the article, I said that we will tell about the generation algorithm unlock codes for Alcatel. In the above archive you will find sources on Delphi for the following models phones alcatel - V670, C700, C701, Playboy, C707, C717, V770, C820, C825, Mandarina Duck, S215, S218, S319, S320, S321, S520, Miss Sixty, S853. Authority source belongs ulymar (ATF Team Member). The code is very structured and to figure it out in it will not be particular problems even for beginner programmers. The form of the compiled application is as follows:

MegaFon for some time not only cellular operator. You can meet stores everywhere, where, in addition to subscriber services, you can also buy a phone. Among other models there are devices and a megaphone brand. It is clear that these are the same ZTE, Huawei, Alcatel, but made specifically for megaphone. Together with them are offered special tariff plans And the conditions of service, and the price of them is much lower than at the fellow. There is one big thing in this matter but. These phones can only work with MegaFon SIM cards. Is it possible to remove this ban? Read about it below.

The unlocking mechanism is quite simple. When you install someone else's sim, the phone asks the unlock code. Enough to introduce it and everything will work. You can enter differently. Open access to the engineering menu using the command *#*#3646633#*#* . Then go as follows: simmelock - Network settings - Unlock - Enter the code.

At first glance, everything is simple. It was only to find cherished numbers. It is advisable to do it for free.

How to get unlock code

You can try for free. Once information about the phone unlocking code has fallen into the network Megafon Login. 2 MS3A. The author of the post quickly realized the error and the article removed, but it did not help. The information flew off the whole Internet and only lazy it did not take advantage. The password approached absolutely for all devices is quite unexpected. We are to the fact that if you have this model, and the old firmware, then boldly Apply Unlock Password 67587048.

We draw your attention to the fact that this method It will work only on old firmware up to 8.1.4. In later versions, freebies are already closed. And these numbers are not suitable and access to engineering menu closed.

Those who have more models are less and have to search for information. If you still want to do everything for free, go to the forum http://forum.gsmhosting.com/vbb/index.php. Look for a section of receiving Unlocking Codes & Log Files Requests / Phone Unlocking Codes & Maps. Next, find a partition that matches the manufacturer of your phone, and leave a request. Not the most successful way. First, you will have to communicate in English. Secondly, no one will answer you immediately, the wait can be very tightened.

There is a better way to buy a password. Price from 200 rubleth. The honesty of these sites we did not check. Soothes the fact that there are no negative feedback on them. The price is also small, so you can risk.

To get the code you will need IMEI Phone and Provider ID. This information is located on the sticker under the battery.

After the password is obtained, insert a new sim and enter it. Note that the number of attempts is limited, so if you caught a password of non-working, then it is better to throw attempts, otherwise the device will become non-working. The same way is suitable for modems.

On the Internet, you can find other ways of "unlocks" of stitched devices. We did not put them in our article, because most often they lead to a breakdown of the device and withdrawing with warranty.

Are you going abroad, and your phone does not work with "other people's" SIM cards?
- You bought a phone in the salons of cellular operators and you were not warned that the phone works only with a specific SIM card?
- You conducted incorrect network unlock codes and your phone does not accept the SIM card at all? (The phone asks SIM BLOCK code)
- You bought a phone with hands, and just now noticed that it is blocked under a specific operator?
- We are familiar!

Unlocking Huawei from the operator

If you bought a phone in stock (and maybe without) in the salons of telecom operators, the likelihood is that your phone works only with one SIM card. Check it is not difficult - insert a single operator's SIM card to the phone! If your phone does not require any passwords - everything is fine, but if you enable the phone tells you about the network lock and asks to enter the code - your phone must be unlocked to work with all SIM cards

This procedure takes some time and depends on whether you can drive it or not.
