How to launch Recovery Mode on Android: a complete guide for system recovery

Restoring a smartphone through Recovery Mode is one of the key skills for owners of Android devices. This mode allows you to reset settings to factory settings, install custom firmware, or fix critical errors when the system refuses to boot. However, incorrect actions in Recovery can lead to complete loss of data or "bricking" the device.

In this article we will analyze all the ways to enter into Stock Recovery (standard recovery) and TWRP (custom), and also explain which operations are safe for beginners and which require experience. You will learn how to bypass the screen lock via ADB, recover deleted files and what to do if your smartphone does not respond to buttons. The instructions are adapted to modern versions Android 12-15 and are relevant for devices Samsung, Xiaomi, Google Pixel, OnePlus and other brands.

What is Recovery Mode and why do you need it

Recovery Mode (recovery mode) is an isolated environment on Android that works independently of the main operating system. It is built into the /recovery internal memory section and starts before loading Android. The main purpose is to diagnose and repair the device when standard methods are not available.

Using Recovery you can:

• 🔄 Reset settings to factory settings (Wipe Data/Factory Reset) - deletes all user data, including accounts and installed applications.
• 📦 Install bootloader updates ( manually (Apply update from ADB or SD card) - useful if the OTA update does not work.
• 🛠️ Fix errors bootloader (Reboot to Bootloader) - helps with cyclic reboot (bootloop).
• 🔐 Bypass screen lock (only on some devices) - if the pattern or PIN is forgotten.

There are two types Recovery:

1. Stock Recovery — standard mode from the manufacturer with limited functionality. Suitable for resetting settings and installing official updates.
2. Custom Recovery (TWRP, OrangeFox) — custom versions with advanced capabilities: creating backups, installing unofficial firmware, accessing the root partition (/system).

⚠️ Attention: Operations in Recovery may lead to loss of warranty if the device is not unlocked for the developer. On some models (for example, Samsung s Knox) reset via Recovery activates the flag RMM Statethat blocks work with banking applications.

How to enter Recovery Mode on different devices

Methods for logging in depend on the manufacturer and model of the smartphone. Below are the current combinations for popular brands. If your device does not respond to buttons, try connecting it to the charger for 10-15 minutes - sometimes a low battery blocks access to Recovery Mode depend on the manufacturer and model of the smartphone. Below are the current combinations for popular brands. If your device does not respond to buttons, try connecting it to a charger for 10-15 minutes - sometimes a low battery blocks access to Recovery.

If the combinations do not work:

• 🔌 Try connecting the device to PC via USB and use the command:

  adb reboot recovery

  (requires enabled USB debugging).

• 🔄 On some devices (Huawei, Honor) the input to Recovery is blocked. In this case, it will help only Fastboot Mode.

What to do if the smartphone does not enter Recovery Mode

If the device does not respond to standard button combinations, the reasons may be different: from hardware faults to software locks. Let's consider typical ones. scenarios and solutions.

1. The device vibrates, but the screen remains black

• 🔋 Check the battery charge - below 5%, many smartphones block access to Recovery.
• 🔌 Connect the original cable and charger for 30 minutes, then try again.
• 🛠️ If the screen is physically damaged, try connecting via ADB (see section below).

2. The brand logo appears and the smartphone reboots

This is a sign of a damaged partition /recovery. Solutions:

• 📥 Install Stock ROM via Fastboot or Odín (for Samsung).
• 🔧 If installed TWRP, try flashing it through fastboot flash recovery twrp.img.

3. The buttons do not work (physical breakdown)

In this case, only a service center or ADB-commands will help:

adb shell reboot recovery

If USB debugging was not turned on in advance, the only option is disassembly devices for short-circuiting button contacts (not recommended for beginners).

⚠️ Attention: On devices with MediaTekprocessors (many models Xiaomi, Realme), incorrect input to Recovery may lead to a reset IMEI. Before experiments, create a backup via MTK Engineering Mode (code ##3646633##).

3. In Recovery select Apply update from SD card (or ADB).
4. Specify the file path and confirm installation.

3. System integrity check

On some devices (Google Pixel, OnePlus), an option is available Verify system integrity. It scans system files for changes (for example, after rooting). If the check fails, flashing is required. data-i="174">Save important data on your PC|Check the battery charge (>50%)|Download the firmware (if an update is planned)|Make sure the firmware is compatible with the device model--> Stock ROM.

Advanced capabilities of Custom Recovery (TWRP)

TWRP (Team Win Recovery Project) —the most popular custom recovery for Android. It allows you to:

• 📀 Create full backups (Nandroid backup) of all partitions (boot, system, data).
• 🔧 Install unofficial firmware (LineageOS, Pixel Experience).
• 🔓 Receive root access via Magisk.
• 🗑️ Clear individual partitions (Dalvik Cache, Internal Storage).

How to install TWRP:

1. Unlock bootloader (OEM Unlock in the developer settings).
2. Download the image TWRP for your model from the official website twrp.me.
3. Connect the device to PC and run the command:

   fastboot flash recovery twrp-3.7.0_12-0-yourdevice.img

4. Reboot into Recovery command:

   fastboot reboot recovery

Key TWRP functions:

⚠️ Attention: Installation TWRP on devices with Dynamic Partitions (Android 10+) may lead to data loss. Before flashing the firmware, check the compatibility on the forums XDA Developers.

How to bypass screen lock via Recovery Mode

If you have forgotten your pattern or PIN code, Recovery Mode can help reset the lock without data loss (on some devices). However, this method does not work on all smartphones due to tightened security Android 9+.

Method 1: Deleting the key file (for Android 5–8)

1. Boot into TWRP (or Stock Recoveryif you have access to ADB).
2. Go to Advanced → File Manager.
3. Open the folder /data/system/ and delete the files:

   gatekeeper.password.key
   gatekeeper.pattern.key
   locksettings.db
   locksettings.db-wal
   locksettings.db-shm

4. Reboot the device.

Method 2: Via ADB (for Android 9–11)

If USB debugging was turned on before blocking:

1. Connect the device to PC and do:

   adb shell
   rm /data/system/gesture.key
   rm /data/system/password.key

2. Reboot your smartphone.

Method 3: Reset via Fastboot (for Samsung)

On devices Samsung with Exynosprocessors, you can reset FRP (Factory Reset Protection) with the command:

fastboot erase frp

After that, run Wipe Data in Recovery.

⚠️ Attention: On Android 12+ s File-Based Encryption (FBE) removing keys will not work - the data will be encrypted and inaccessible without a password. The only way out is a complete reset (Format Data v TWRP).

Data recovery after a reset via Recovery

If you performed Wipe Data without a backup, the chances of getting data back depend on the type of memory and version Android:

• 📁 Internal memory (eMMC/UFS): After a reset, the data is not physically deleted, but is marked as free. They can be restored with apps like DiskDigger or Dr.Fone, but only if no new files were written to the device.
• 🔒 Encrypted memory (FBE): On Android 10+ data is encrypted with a unique key, which is erased when reset. Recovery almost impossible without the original password.
• 💾 SD card: Files on the external card are not affected when resetting via Recovery (if not selected Format SD card).

Recovery apps:

How to increase the chances of recovery:

1. Do not write new data to the device after the reset.
2. Connect your smartphone to PC in MTP mode and scan the internal memory directly (not through TWRP).
3. For rootdevices, use TWRP + Nandroid backup before resetting.

⚠️ Attention: On devices with UFS 3.1/4.0 (for example, Samsung Galaxy S22+, OnePlus 11), data recovery after Format Data v TWRP is almost impossible due to hardware encryption.
