iPhone activation failure: causes and features

The described problem is typical for smartphones that have been updated to the iOS 11 operating system. In this OS, the device is activated using a UDID (unique device identifier), which is generated based on several identifiers entered in NAND, the processor and the Wi-Fi chip (serial number, processor ID , IMEI, Bluetooth and Wi-Fi MAC addresses). If at least one of these identifiers is incorrect, then the iPhone iOS 11 activation fails and the operation of the device is disrupted.

The problem occurs for two reasons:

• When replacing the NAND memory chip, the MAC addresses were incorrectly registered;
• Malfunction of the modem part and, as a result, the absence of IMEI.

A separate problem is the failure to activate the iPhone 5s refurbished in China by assembling two boards into one. In this case, the processor and modem part are from two different phones, as a result of which an incorrect UDID is generated.

iPhone 5s and higher activation failure: how to fix it

Regardless of the problem, iPhone 6 and earlier and later models activation failure is solved only at the hardware level. If the problem is in the NAND memory, then everything is solved simply - the microcircuit is soldered, the correct Wi-Fi and Bluetooth MAC addresses are entered into it with the programmer (according to the IMEI GSX report), and then the phone is flashed.

If the iPhone activation failed due to the modem part, then the corresponding chip (s) is replaced. And devices assembled from two parts can only be repaired by replacing the entire system board.

The OnService service center performs all types of repairs necessary to resolve the “iPhone activation failed” error on iOS 11 efficiently, quickly and at affordable prices.

After purchasing a fresh iPhone, iPod or iPad, or simply performing a hard reset, for example, to fix problems with the device, the user must complete the so-called activation procedure, which allows you to set up the device for further use. Today we will look at how device activation can be done through iTunes.

Activation via iTunes, that is, using a computer with this program installed on it, is performed by the user if the device cannot be connected to a Wi-Fi network or use a cellular connection to access the Internet. Below we will take a closer look at the procedure for activating an apple device using the popular iTunes media combine.

How to activate iPhone through iTunes?

1. Insert the SIM card into your smartphone and then turn it on. If you are using an iPod or iPad, start the device immediately. If you have an iPhone, then without a SIM card you will not be able to activate the gadget, so be sure to consider this moment.

2. Swipe to continue. You will need to set the language and country.

3. You will be prompted to connect to a Wi-Fi network or use a cellular network to activate the device. In this case, neither one nor the other suits us, so we immediately launch iTunes on the computer and connect the device to the computer using a USB cable (it is very important that the cable is original).

4. When iTunes detects the device, click on its thumbnail icon in the upper left area of ​​the window to go to the control menu.

5. Following on the screen can develop two scenarios. If the device is linked to your Apple ID account, then to activate it you will need to enter the email address and password from the identifier linked to the smartphone. If you are setting up a new iPhone, then this message cannot appear, which means that you should immediately proceed to the next step.

6. iTunes will ask what needs to be done with the iPhone: set it up as new or restore from a backup. If you already have a suitable backup on your computer or iCloud, select it and click the button "Proceed" to have iTunes move on to activating the device and restoring information.

7. The iTunes screen will show the progress of the activation and restore process from the backup. Wait for the end of this procedure and in no case disconnect the device from the computer.

8. Once the activation and restore from the backup are completed, the iPhone will go into reboot, and after restarting the device will be ready for the final setup, which includes setting up geolocation, enabling Touch ID, setting up a digital password, and so on.

In general, at this stage, iPhone activation via iTunes can be considered completed, which means that you can safely disconnect your device from your computer and start using it.

With the release of 11 iOs, many users are faced with such a problem as " iPhone activation failure". First of all, the owners of "restored" devices (they are "refs") faced such a problem. This happens after updating to 11 iOs via iTunes, or after factory reset on an already updated device. Owners of iPhones that have undergone unskilled repairs may also encounter such a problem, usually iPhones on which Flash memory has been changed and this was done without observing all the replacement rules.

The reason for this failure is due to the fact that in version 11 of iOs the device activation algorithm was changed. Previously, the correct serial number (which is stored in NAND memory) and the IMEI number (which is stored in the modem) were enough for activation. Now, for activation, the following numbers must match the activation base: Serial number + IMEI + Wi-Fi MAC address of the module + Bluetooth MAC address of the module + processor serial number. All this data is entered into the Apple database when devices leave the assembly line, and for each iPhone, iPad, this bundle is unique. If at least one of these numbers does not correspond to those that were assigned to it from the factory, then iPhone won't turn on and when you try to activate it will give an activation error. To fix the error, you first need to figure out which of the numbers does not match the base. Most often, these are Wi-Fi and Bluetooth MAC addresses. In this case, you need to unsolder the NAND memory and correct the data. If the problem occurs on the iPhone 5s, then most likely it will not be possible to fix the situation, since in the restored 5s, most often the processor is not native, which corresponds to the modem and memory serial number.

The problem with incorrect MAC addresses in our service center is solved for any model from iPhone 5s to iPhone X. This procedure takes from 1.5 to 24 hours in time. This time variation is due to the fact that these addresses have to be ordered from third parties that have access to Apple's databases. How does the troubleshooting process work:

1. NAND memory is soldered.

2. MAC addresses are ordered.

3. As soon as a response is received on the request for addresses, they are written on the programmer to the NAND memory of your device (or to a new one if you want to increase the volume).

4. The memory is soldered back and the device is flashed to the latest current version of iOS.

Also, the iPhone is not activated if it is locked to the operator (activation will require the SIM card of the operator to which it is locked) or is in the "Himera" status (blocking devices directly by Apple itself, with which any fraudulent activities were associated or were stolen from companies).

In 2020, the iPhone from Apple is gaining even more popularity. When trying to reinstall the firmware from an old version to a new one, an error may occur in the form of a failure to activate iphone 4/4s/5/5s/6/6s/7/X. We have prepared a detailed article that tells about all the nuances of the work.

Bugs in work can occur on any operating system, but among mobiles, IOS is the most vulnerable. Common reasons for activation failure are:

• unstable operation of the company's servers, in such cases it is displayed - it is not possible to contact the server;
• the server is temporarily unavailable - means that repairs are underway and the update can be downloaded from the official iTunes;
• an authentication error may occur due to an unstable connection, as well as a hacked firmware and an old account;
• cellular network error when replacing SIM, in this case, you need to replace the card with the operator or change the provider;
• Apple Id verification failure may occur when connecting to a computer through a broken cord.

Apple server is temporarily unavailable

When a message appears on the screen of a mobile phone, you should make sure that this is really a problem with the servers. You can do this by visiting the official website, there will always be up-to-date news about the state of the servers. If technical work is being done, then it is worth waiting and trying later.

Reset

Devices of dubious assembly may stop working after returning to the factory settings. When making a purchase from an unauthorized dealer, there is a high risk of getting a gadget with fake parts and subsequently a non-working device. At risk are devices on the IOS 11 platform and above. If after resetting the iPhone activation error, the reasons are as follows:

• repair with non-original spare parts;
• when the server is turned on, the companies do not recognize the replaced parts and block the phone.

To avoid trouble, it is worth making purchases and repairs in official services.

iPhone hardware issues

Problems can occur due to glitches in the phone. These include:

• SIM card visibility failure;
• constant network search, even without a SIM card.

The master in the service center can determine the exact problem.

iOS 11 and iOS 12 activation issue on refurbished phones

Owners who bought Chinese fakes from AliExpress face difficulties. The assembly of devices is a hodgepodge of different spare parts imitating the original ones. When disassembling such phones, it may turn out that the board remains original, but some modules can be replaced.

In the fight against fakes, the company introduces radical methods. When activated, a signal is sent to the company's servers, and all details are checked. If a serial number or Mac address does not match, it will not be possible to activate.

Activation Lock installed

An option to prevent unauthorized access to data. The active mode will be evidence that the gadget was obtained illegally. It is impossible to bypass the security system by flashing, since all data is tied to an account. When you try to restore access through official services, a notification will appear about entering the Apple Id and the email address associated with the account.

SIM card not supported

A message of this type can be displayed for several reasons. The signal encoding does not match the phone's radio module, or the card is blocked. In such cases:

• contact the provider for a new card;
• try to activate with another SIM card;
• check the information regarding the phone on the official website;
• contact the official representative.

Internet connection problems

In cases of an unstable connection, activation will not be possible. You will receive the error Unable to contact the server. Possible reasons:

• there is a ban on data transfer;
• restriction of access to servers.

You can resolve the issue by contacting the provider providing the services, as well as by checking the smartphone settings.

How to fix "your iPhone could not be activated because it could not contact the activation server"

The error may be caused by technical work on the server or access blocking. To fix it:

• go to the company's website and check the information about the health of the servers and the release of new firmware;
• check access via Wi-Fi router.

Some routers are configured to block the domain and prevent you from taking action. Also, during the release of new versions, a high percentage of server load is observed, and the connection may be interrupted. In this case, you need to wait and try again the next day.

Cellular network activation failure PDP authentication error on iPhone - what to do?

When connecting to servers through a mobile device, an authentication error may occur, which means the iPhone could not be activated because it was not possible to obtain activation information from it. You can check and fix problems by:

• leave a request on the hotline of the service provider;
• when confirming a fault on the line - wait;
• restore the connection manually, through the "Settings" item;
• go to the "Cellular connection" section, find "Data settings";
• open "Cellular data network" and scroll to the item "APN";
• pre-rewrite all the data - will be needed for further input;
• delete all data from "APN", and reboot;
• we try to establish a reconnection by going to the browser;
• if unsuccessful, enter the previous data in "APN", and try again.

If the problem has not been fixed, then we require the operator to take action.

What to do if iPhone activation fails and needs an update after a factory reset

After the iPhone activation fails, an update is required - you should reinstall the firmware. The update can be done in several ways:

• by connecting the phone to the computer and installing a new firmware through the official website;
• update via iTunes.

If cellular network activation fails, restarting your iPhone will help. Performing a full Hard Reset:

• the "Home" and "Lock" keys are pressed simultaneously;
• after 8-10 seconds are released and the gadget automatically starts the reboot process.

Upon completion, the applications will be restored.

Using a stable internet connection

Problems that occur when connecting to servers are solved with a stable connection. By connecting to Wi-Fi, the connection will no longer be interrupted and the activation will proceed without failures.

Activation via iTunes

In cases where internet connection did not solve the problem. The firmware is being downloaded via iTunes, before starting, you should update to the latest version. Steps:

Update

In cases where programs fail and it is not possible to activate an account, an update will help. The process does not take much time and for holding a fairly stable internet or computer.

SIM card check

Before contacting the support of the provider, it is worth checking whether the sim is inserted correctly. If inserted on the wrong side, then put it in the correct slot, and also check the activity of the card.

Mobile network blocking check

A common reason for authentication being denied is a blocked data transfer. You can check the setting in the network settings.
