Accidental reset, unsuccessful update or virus attack - and your Androidsmartphone turns into a “blank slate”. All photos, correspondence, contacts and documents disappeared in an instant. But don’t panic: even after complete formatting, the chances of returning some of the data remain. In this article we will look 7 proven recovery methodsfrom simple (via cloud backups) to complex (using ADB and specialized software).

The main thing rule: the sooner you start acting, the higher the probability of success. Once deleted, the files do not physically disappear - they are simply marked as "free space". As long as new data does not overwrite old data, it can be retrieved. But every hour of delay reduces the chances by 10–15%.

If you have already tried to recover data and nothing worked, do not despair. The article has a section about alternative methodsthat work even when standard tools are powerless. And for those who are afraid of repeating the mistake, we have prepared prevention checklist for the future.

📊 What did you lose after resetting Android?

Applications and their data
I don’t know what exactly

1. Check cloud backups

The first thing to do is check synchronization with cloud services. Modern Androiddevices automatically save part of the data in Google Account, Mi Cloud (for Xiaomi), Samsung Cloud or other branded storage facilities. Here is what is usually backed up:

  • 📱 Contact — synchronized with Google Contacts or the manufacturer’s proprietary cloud.
  • 📷 Photos and videos —if Google Photos or a similar service was enabled.
  • 📝 Notes and calendars - via Google Keep, Samsung Notes etc.
  • 🎮 Data applications - some games and apps (for example WhatsApp) save backups in the cloud.

To recover data from Google Account:

  1. Open Settings → Accounts → Google.
  2. Select your profile and click Account synchronization.
  3. Make sure that all the necessary items (contacts, calendar, disk) are enabled.
  4. Wait for synchronization to complete - the data will appear automatically.

For photos:

  1. Install the application Google Photos.
  2. Log in using the same account you had before the reset.
  3. Go to Library → Trash (if files were recently deleted) or check the folder Archive.
⚠️ Attention: If you used Mi Cloud on Xiaomi or Samsung Cloud, check the availability of backup copies in your personal account on the manufacturer’s website. Some brands store backups for only 30 days!

2. Recovery through manufacturer's proprietary utilities

Large brands (Samsung, Xiaomi, Huawei, Oppo) offer their own tools for backup and recovery. These utilities often work more efficiently than universal solutions, since they take into account the specifics of the firmware.

Examples of proprietary solutions:

Brand Utility What it restores Where to download
Samsung Samsung Smart Switch Contacts, messages, photos, applications Official website or Galaxy Store
Xiaomi Mi PC Suite Backups from Mi Cloud, files from the device mi.com (section "Support")
Huawei HiSuite Data applications, SMS, call log Official website Huawei
Oppo/Realme Oppo Phone Manager Multimedia, contacts, system settings Support Oppo/Realme

Instructions for Samsung Smart Switch (similar for others utilities):

  1. Install the app on your PC (samsung.com).
  2. Connect your phone via USB (turn on USB debugging v Settings → About phone → Build number - press 7 times).
  3. Select Restore and specify the path to the backup (if it is saved on the PC).
  4. Confirm the restoration of the required ones data.
⚠️ Attention: Branded utilities may not work if you changed the firmware to custom (for example, LineageOS). In this case, use the universal methods from the following sections.
💡

If you have Samsungcheck the folder Samsung\Backup on the memory card - sometimes backups are saved there automatically.

3. Using specialized apps (without root)

If there are no cloud copies, and proprietary utilities did not help, it’s time to turn to third-party software. The best apps for data recovery from Android without root access:

  • 🛠️ DiskDigger - scans internal memory and card SD, recovers photos, videos, documents.
  • 🔍 EaseUS MobiSaver —supports recovery of messages, contacts, call history.
  • 📱 Dr.Fone (Wondershare)—a universal solution with a high percentage of successful recovery.
  • 💾 Recuva —free utility for recovering files from a memory card (requires connection to a PC).

Step-by-step guide for DiskDigger:

  1. Download and install DiskDigger from Google Play.
  2. Launch the app and select the scan type:
    • Basic scanning - fast, but less deep.
    • Full scan —takes longer, but finds more files.
  • Wait for the process to complete (can take from 10 minutes to several hours).
  • Tick the boxes of the files you want to recover and click Recover.
  • Save the data to a memory card or to the cloud (do not restore to the phone's internal memory!).

    • Limitations of non-root methods:

    • Not all file types are recovered (for example, messages from WhatsApp or Viber often remain unavailable).
    • The likelihood of success depends on how much new data was written after deletion.
    • Some apps require payment to restore large files.

    Turn off Wi-Fi and mobile data

    Charge your phone to at least 50%

    Free up space on the memory card (if you are restoring there)

    Do not install new applications until the process is completed-->

    4. Recovery using root access (for advanced)

    If your device has superuser rights (root), the chances of successful recovery increase significantly. With root you can scan system partitions, where “traces” often remain deleted files. But be careful: incorrect actions can lead to total loss of data or “brick” of the device.

    Popular tools for working with root:

    • 🔧 TWRP Recovery + ADB - to create a full backup section /data.
    • 📂 Root Explorer —for manually searching for leftover files in folders /data/data.
    • 🛠️ Undelete for Root Users —specialized recovery software.

    Instructions for recovery via TWRP i ADB:

    1. Install TWRP Recovery (if not already installed).
    2. Reboot the phone into mode Recovery (usually Power + Volume up).
    3. Connect the device to the PC and open the command line.
    4. Run the command to create an image of the partition /data: 
      adb pull /dev/block/mmcblk0pXX data.img

      (replace mmcblk0pXX with the current partition - you can find it through adb shell ls /dev/block).

    5. Scan the resulting one data.img using PhotoRec or TestDisk on PC.
    ⚠️ Attention: Working with root i ADB requires experience. An error in the commands can lead to damage to the bootloader. If you are not sure, contact a specialist.
    What to do if the files are damaged after recovery?

    Try to open them on your PC using specialized apps:

    - For photos: PhotoRec or Stellar Phoenix Photo Recovery.

    - For videos: VLC Media Player (has built-in recovery tools).

    - For documents: Microsoft Office Recovery Tool or OpenOffice.

    If the files do not open, try converting them to another format through online services (for example, CloudConvert).

    5. Recovering deleted messages and call history

    Messages from SMS, WhatsApp, Viber and the call log are the most difficult to recover. But there are several that work methods:

    For SMS and call log:

    • 📱 If backup was enabled in Google Drive, check Settings → Google → Restore.
    • 💾 Use SMS Backup & Restore (if you previously made a backup).
    • 🔍 For devices with root try GT SMS Recovery or Super Backup.

    For WhatsApp:

    1. Reinstall WhatsApp and log in using the same number.
    2. If there was a backup in Google Disk, the application will offer to restore it.
    3. If the backup is local (in a folder /sdcard/WhatsApp/Databases), rename the file msgstore.db.crypt14 to msgstore.db and move it to the folder Databases.

    For Viber and Telegram:

    • 🔄 Viber synchronizes history with the cloud - reinstall the application and log in with the same account.
    • ☁️ Telegram stores messages in the cloud, but local history (secret chats, media files) may be lost.
    💡

    If you used WhatsApp Business, backup copies can be stored separately from the usual WhatsApp. Check the folder /sdcard/WhatsApp Business/Databases.

    6. Alternative methods: when nothing helps

    If standard methods do not work, remain non-standard solutions. They require more time and effort, but sometimes they save you in hopeless situations.

    Method 1: Extracting data through Chip-Off

    • 🔧 Suitable for phones with a damaged board, but intact memory (eMMC or UFS).
    • 💰 Cost: from 5,000 to 20,000 rubles (depending on the model).
    • ⏳ Duration: 1–3 days.

    The memory chip is removed and connected to a special programmer that reads the data bypassing operating system.

    Method 2: Contacting the laboratory

    • 🏥 Specialized centers (for example, Hetman Recovery or ACE Data Recovery) work with physically damaged drives.
    • 🔬 They use professional equipment to recover data at the chip level.
    • ⚠️ Risk: with unqualified intervention, the memory chip can be permanently damaged.

    Method 3: Recovery via JTAG

    • 🔌 Connection to test contacts on board for direct memory access.
    • 🛠️ Requires soldering and specialized software (RIFF Box, Easy-JTAG).
    • 📉 Efficiency: ~60–70% for phones before 2020, lower for new models.
    ⚠️ Attention: Methods Chip-Off and JTAG may void the warranty for the device. Before contacting service, check whether the warranty is still valid.

    What NOT to do after resetting:

    • ❌ Do not install new applications - they can overwrite deleted data.
    • ❌ Do not format the memory card.
    • ❌ Do not update the firmware immediately after reset.
    • ❌ Do not connect the phone to the PC in Media device (MTP) unnecessarily.

    FAQ: Frequently asked questions about data recovery

    Is it possible recover data if the phone does not turn on?

    Yes, but the methods depend on the cause of the breakdown:

    • If the screen is broken, but the phone responds to connecting to a PC, use ADB or specialized software (Dr.Fone).
    • If the phone does not show signs of life, you will need Chip-Off or JTAG (contact the service center).

    The cost of recovery in this case starts from 3,000 rubles.

    How much does it cost to restore data at the service center?

    Prices depend on complexity:

    • Software recovery (without disassembly): 1,500–5,000 ₽.
    • Chip-Off (removing the memory chip): 5,000–20,000 ₽.
    • JTAG (soldering contacts): 8,000–25,000 ₽.

    In state expert centers (for example, at the Ministry of Internal Affairs), recovery can be free if the data is needed for court.

    Is it possible to restore data after flashing?

    There are chances, but they are lower than after a regular reset What is possible. do:

    • If the firmware was "on top" (without formatting /data) - try DiskDigger or PhotoRec.
    • If /data formatted - only Chip-Off.

    Important: after flashing do not write new data to the phone.

    How to recover data from a damaged memory card?

    Try the following steps:

    1. Connect the card to the PC via a card reader.
    2. Use TestDisk or Recuva for scanning.
    3. If the card is not detected, try flashing its controller using Flash Drive Information Extractor.

    If the card is physically damaged (for example, after falling into water), contact the laboratory - independent attempts can aggravate the situation.

    Do “magic” apps like this work WonderShare 100%?

    No. Efficiency depends on:

    • Type of deleted files (photos are recovered more often than messages).
    • Time elapsed after deletion.
