How to completely remove a holographic key from Android: official and alternative methods

The holographic key on Android is a virtual security that replaces the physical SIM card PIN code. It appears after activating the function eSIM or when transferring a number between devices through an operator. Unlike a regular graphic key, a holographic one is tied to the operator’s profile and cannot be removed by a standard reset. Many users encounter a problem when, after changing a phone or reinstalling the firmware, the system requires you to enter this key, although it has never been installed.

In this article we will analyze all official and non-obvious ways to remove a holographic key, including methods for locked devices. We will pay special attention to the nuances for popular brands - Samsung, Xiaomi, Huawei and Google Pixel, since their algorithms for removing protection are different. We will also consider the risks and consequences of incorrect actions so that you can choose a safe path.

⚠️ Warning: Some methods require access to an operator account or factory settings. If the device is stolen, these methods will not work - the holographic key is tied to IMEI and the owner's data.

What is a holographic key and why does it appear

A holographic key is virtual security codewhich is generated by the telecom operator when activation eSIM or transferring the number to a new device. Unlike the standard SIM card PIN code, it is stored in a protected area of the smartphone’s memory (/efs or /modemst1) and is not reset even after hard reset.

Main reasons for its appearance:

• 🔄 Transferring a number between devices through an operator (for example, when buying a new phone while keeping the old number).
• 📱 eSIM activation - a virtual SIM card that replaces a physical chip.
• 🔧 Firmware update or resetting the settings, after which the system requires re-authentication.
• 🚨 Operator blocking if fraud is suspected (for example, if the device’s IMEI is blacklisted).

The key can be requested in different scenarios:

• 📵 When you turn on the phone after turning it off.
• 🔄 After removing/inserting the SIM card.
• 🔒 When you try to change the network settings (Settings → Mobile network).

⚠️ Attention: If you bought the phone with hands and encountered a holographic key, there is a high probability that the device is listed in the stolen database. Check the IMEI through the service SwiperCheck or similar.

Official ways to remove a holographic key

The most reliable method is to contact the operator. communication, since the key is tied to its infrastructure. However, not all operators provide this option. Let's consider proven options:

1. Through the operator's support service

Most Russian operators (MTS, Beeline, MegaFon, Tele2) can reset the holographic key at the request of the owner:

• 📄 Passport (to confirm identity).
• 📞 Phone number, linked to device.
• 🔢 IMEI phone (you can find out through *#06#).
• 📝 Service agreement (if saved).

The procedure takes from several hours to 3 business days. The operator sends an SMS with an unlock code or removes the protection remotely.

⚠️ Attention: If the phone was purchased on credit and not paid for, the operator may refuse to remove the lock until the debt is fully repaid.

2. Through the operator's application

Some. operators (for example, MTS and MegaFon) allow you to control the holographic key through the official application:

1. Open the operator's application (for example, My MTS).
2. Go to section SIM Management → Security Settings.
3. Select the option Reset holographic key.
4. Confirm the action via SMS or call from operator.

If there is no such option, try updating the application or contacting the support chat directly from it.

3. Via USSD commands

Some operators support unlocking via USSD requests:

• For MTS: *111*1234# (where 1234 is the last digit of the number).
• For Beeline: *110*09# → select SIM management.
• For MegaFon: *105*00# → Security settings.

If the command did not work, the operator could change the combination. Check the current code with the support service.

Unofficial removal methods (for experienced users)

If the operator refuses to help or you are not the original owner of the device, you can try alternative methods. These methods require technical skills and can lead to data loss or blocking of the phone!

1. Reset via Engineering Mode (for devices on MTK)

On smartphones with a processor MediaTek (many models Xiaomi, Realme, Oppo), you can try resetting the key through the engineering menu:

1. Enter the code ##3646633## (or ##4636## for new versions).
2. Go to Connectivity → CDS Information → Radio Information.
3. Select Phone 1 (if two SIM cards).
4. In the field AT+ enter the command:

   AT%ESIM=0

   and click Send AT Command.

5. Reboot the device.

If the command does not work, try an alternative:

AT%ESIM=1,0

⚠️ Attention: Incorrect commands in the engineering menu may disrupt the operation of the communication module. Do not experiment if you are not sure. actions.

2. Removal via ADB (for an unlocked bootloader)

If the phone is unlocked bootloader, you can try deleting the key via Android Debug Bridge:

1. Install ADB Tools on your PC and connect the phone in debugging mode (Settings → For developers → USB debugging).
2. Open the command line and enter:

   adb shell
   su
   rm /data/data/com.android.phone/files/.holographic_key

3. Reboot device.

If the file is not found, try alternative ways:

• /data/system/users/0/holographic_key
• /efs/carrier/holographic_key

🔹 Important: This method requires root access. On new devices (Android 12+), it is almost impossible to get it without losing data.

3. Flashing via Odin (for Samsung)

On devices Samsung the holographic key is stored in the section EFSIt can be reset by completely flashing it via Odin:

1. Download the official firmware for your model from the website Sammobile.
2. Unzip the file and find the file CSC_... (for example, CSC_OXM...).
3. Replace it with HOME_CSC (to avoid resetting the data).
4. Run Odin, connect the phone in the mode Download Mode (Volume down + Power + Bixby).
5. Upload the files into the appropriate fields and press Start.

⚠️ Attention: Incorrect firmware can turn the phone into a “brick”. for your model!

What to do if the phone does not turn on after flashing?

If the device does not respond after flashing via Odin, try:

1. Repeat the procedure with the original CSC file (not. HOME_CSC).

2. Flash only BL (Bootloader) and CP (Modem) without AP and CSC.

3. Use a combination of buttons to force a reboot (depending on the model).

If all else fails, contact a service center - the eMMC memory may be damaged.

Specifics for different brands

Algorithms for working with a holographic key differ depending on the manufacturer. Let's consider the nuances for popular brands:

Brand	Features of the holographic key	Recommended removal method
Samsung	The key is stored in the section EFS. Often appears after updating via Smart Switch.	Firmware via Odin or contacting Samsung Service.
Xiaomi	Linked to account Mi Account. Can block access to network settings.	Reset via Mi Flash Tool or engineering menu (##4636##).
Huawei	The key is activated when using Huawei Mobile Services (HMS).	Contact via Huawei Support or reset via HiSuite.
Google Pixel	Often associated with eSIM from Google Fi. Blocks access to the mobile network.	Removal via Pixel Repair Tool or contacting the operator.

🔹 Important for Xiaomi: If the phone is linked to an account Mi Account, before resetting the key, you must log out of the account in the settings (Settings → Accounts → Mi Account →). ExitOtherwise the device will be blocked completely.

💡

Before any manipulations with the holographic key, make a backup copy of the partition EFS via TWRP or ADB. This will help restore IMEI and network settings if something goes wrong.

What to do if nothing helps

If nothing helps one of the methods did not work, radical measures remain. They should be used only as a last resort:

1. Full reset via Fastboot

On some devices (for example, Google Pixel or OnePlus) you can erase the partition with the key via fastboot:

1. Switch the phone to mode fastboot (Volume down + Power).
2. Connect to the PC and enter the command:

   fastboot erase carrier

3. If it doesn’t work, try:

   fastboot erase modemst1
   fastboot erase modemst2

4. Reboot the device.

⚠️ Attention: These commands will delete all network settings, including IMEI. After a reboot, you may need to restore it through a service center.

2. Replacing the motherboard

If the holographic key is hardwired to the hardware identifier (for example, on iPhone s eSIM or some Samsung, the only way out is to replace the motherboard. This is an expensive procedure (from 5,000 to 20,000 rubles), but it is guaranteed to remove the blockage.

Before replacing the board:

• 🔍 Make sure that the new board is not tied to another device.
• 📄 Check if the warranty is still valid (most services will remove the warranty after such a repair).
• 🔧 Find a service that specializes in micro soldering (for example, Apple repair or Samsung Service Partner).

3. Legal methods

If the phone was purchased second-hand and the previous owner refuses to help, you can:

• 📝 Contact the police with a report of fraud (if there is evidence deception).
• 🏛 File a lawsuit against the operator if he refuses to remove the block without reason.
• 🔄 Return the phone to the seller under the law "On the Protection of Consumer Rights" (if the purchase was less than 14 days ago).

🔹 Important: The legal path is long and does not guarantee results, but in some cases this is the only way to return money or unlock the device.

💡

If the phone is locked with a holographic key and is not your property, any attempt to bypass the protection may be regarded as a violation of Article 272 of the Criminal Code of the Russian Federation ("Illegal access to computer information").

How to avoid problems with a holographic key in in the future

To avoid being blocked again, follow simple rules:

• 📱 Buy phones only from official sellers (stores Svyaznoy, M.Video, Samsung Store etc.).
• 🔄 Before selling your phone:
  • Remove all locks (Settings → Security → Screen lock).
  • Log out of your Google account and manufacturer (Mi Account, Samsung Account etc.).
  • Reset to factory settings (Settings → System → Reset).
• 📡 When transferring a number to a new device:
  • Check with the operator whether it will be activated holographic key.
  • Save all codes and passwords that support provides.
• 🔒 Do not use unofficial firmware —they can disrupt the operation of the module eSIM.

⚠️ Attention: If you often change phones and use eSIM, keep a log with activation codes and linked IMEI. This will make unlocking easier in the future.

FAQ: Frequently asked questions about the holographic key

Is it possible to remove the holographic key without losing it data?

Yes, but only if you know the code or the operator agrees to reset it. Unofficial methods (via ADB or the engineering menu) require root access, which on new devices cannot be obtained without resetting. If there is a lot of data on the phone, it is better to make a backup via Smart Switch (for Samsung) or Google Backup before any manipulations.

Why does the operator refuse to remove the holographic key?

Frequent reasons:

• 📵 The phone is listed in the stolen/lost database.
• 💰 The number has debt on a tariff or loan.
• 🔄 The number was transferred from another operator, and the previous one did not confirm the unlocking.
• 📄 There are no documents confirming ownership.

Specify the reason for the refusal and try to eliminate it (for example, pay off the debt or provide additional documents).

Is it possible to bypass the holographic key on a phone with a broken screen?

Yes, but it is difficult. Options:

1. Connect the phone to the PC via ADB and try entering the unlock command blindly.
2. Use OTG cable + mouseto control the screen without a touchscreen.
3. Contact a service center - they can connect to the motherboard directly.

⚠️ Without a working screen the chances of success are minimal, especially if the unlock code is not known.

A holographic key and a graphic key are the same thing?

No, these are different things:

• 🔐 Graphic key is a custom screen lock that you set yourself.
• 📡 Holographic key is a network blocking that is imposed by the telecom operator.

The graphic key can be reset via Find My Device (Google) or Smart Lock, and the holographic key can only be reset through the operator or technical manipulation.

After deleting the holographic key, the phone stopped receiving the network. What should I do?

This means that when the key was removed, the network settings were damaged. Try:

1. Restore the partition EFS from a backup copy (if you did). backup).
2. Enter the command in the engineering menu:

   AT%IMEI?

   If IMEI is displayed as NULL, restoration through the service center is required.

3. Flash the phone with the official firmware with a full reset (CSC, and not HOME_CSC).

If all else fails, contact your operator - perhaps the number was deactivated due to the key being reset.
