System updates on Android are designed to improve performance, close vulnerabilities and add new features. However, often after installing the latest firmware, users encounter slowdown, interface bugs or incompatibility with familiar applications. In such cases, the logical solution is to roll back to the previous version OS. But here lies the catch: Google smartphone manufacturers (Samsung, Xiaomi, OnePlus etc.) often block the ability to โ€œdowngradeโ€ due to security risks.

In this article we will look at legal and unofficial ways to remove updatestheir consequences for the warranty and performance of the device, as well as cases when a rollback is impossible without data loss. Important: the procedure varies depending on Android version (from Android 10 to Android 14), smartphone model and availability. Some methods require technical skills - for example, working with unlocked bootloader. Some methods require technical skills, such as working with ADB or custom recovery TWRP.

Why you may need to uninstall an update

Reasons for rolling back updates fall into two categories: technical problems and subjective discomfort. Let's consider typical scenarios:

  • ๐Ÿข Performance: after upgrading to Android 13/14 the device began to โ€œslow downโ€, get hot or quickly discharge. This is often due to unoptimized software for older chipsets (for example, Snapdragon 6xx or Mediatek Helio).
  • ๐Ÿ”„ Instability: random reboots, system application crashes (com.android.systemui), type errors "The android.process.media process has stopped".
  • ๐Ÿ”’ Function blocking: the manufacturer removed useful features (for example, Samsung removed support MST for contactless payments in some regions).
  • ๐Ÿ“ฑ Incompatibility: critical applications (banking, corporate or games) stopped working due to changes in API or security policies.
  • ๐ŸŽจ Interface changes: new design (Material You v Android 12+) or the navigation gestures seem awkward.

Before you roll back, check:

  1. Is reset to factory settings after the update Sometimes this solves the problem? problems without downgrading.
  2. Are alternative firmware (for example, LineageOS) for your model that are free from the bugs of the stock version.
  3. Has the period expired device support by the manufacturer (relevant for smartphones older than 3-4 years).
โš ๏ธ Attention: On devices with Android 11 and newer, rollback through standard settings is often blocked due to the mechanism Rollback Protection. Attempt to downgrade may trigger anti-rollback flag, which will lead to complete loss of functionality (brick) without the possibility of recovery through ODIN or Fastboot.

Method 1: Rollback through settings (official method)

The safest, but also the most limited option. Works only if:

  • ๐Ÿ“ฑ Manufacturer has not blocked downgrade (relevant for Google Pixel, some models Xiaomi and Motorola).
  • ๐Ÿ”„ The update was installed recently (usually within 1-2 weeks).
  • ๐Ÿ“ฆ Saved on the device backup of the previous version (function Automatic rollback to Android 12+).

Instructions:

  1. Open Settings โ†’ System โ†’ System update.
  2. Click on the three dots (โ‹ฎ) in the upper right corner and select Update history.
  3. Find the latest update and tap on it. If the option Cancel update or Return to the previous version is available, confirm the action.
  4. Wait for the reboot (takes 5-15 minutes).

If the item Cancel update is not present, it means that the manufacturer has disabled it. In this case, proceed to the following methods.

Method 2: Uninstalling updates via ADB (for experienced)

Tool ADB (Android Debug Bridge) allows you to manage system packages, including rolling back updates without data loss. The method is suitable for devices with unlocked USB debugging and works on most versions Android (except Android 14 with restrictions ADB).

You will need:

  • ๐Ÿ–ฅ๏ธ Computer with installed Platform Tools (includes adb i fastboot).
  • ๐Ÿ”Œ Cable USB-Type C (preferably original).
  • ๐Ÿ“ฑ Enabled USB debugging (Settings โ†’ About phone โ†’ Build number (tap 7 times) โ†’ Developer settings โ†’ Debugging via USB).

Step-by-step guide:

  1. Connect your smartphone to the PC and confirm trust in the device in the dialog box.
  2. Open the command line (cmd on Windows or Terminal on macOS/Linux) in the folder with platform-tools.
  3. Run the command to check the connection:
    adb devices

    The serial number of the device should appear.

  4. Find out the name of the latest update package:
    adb shell pm list packages | grep update

    Usually it is something like com.google.android.ota or com.samsung.wsp.odm.

  5. Remove the update package (replace package.name with the real name):
    adb shell pm uninstall -k --user 0 package.name
  6. Restart the device:
    adb reboot

Critical detail: This method only removes the update files, but does not roll back the firmware itself. If the update has already been applied to the system partition, a complete flashing will be required. On devices with a locked bootloader, the command may return an error. This means that the manufacturer has prohibited modification of system packages. In this case, only unlocking will help

โš ๏ธ Attention: On devices with Android 10+ and locked bootloader command pm uninstall may return an error INSTALL_FAILED_VERIFICATION_FAILURE. This means that the manufacturer has prohibited modification of system packages. In this case, only unlocking will help bootloader (see Method 4).
What to do if ADB does not see the device?

1. Check the drivers (install Google USB Driver or driver from the manufacturer).
2. Try another USB port (preferably USB 2.0).
3. In the developer settings, enable the "Cancel debugging authorization" option.
4. Reboot both devices.

Method 3: Reset to factory settings with firmware rollback

If the previous methods did not work and the device became unstable, you are left hard reset with restoring the old version Android. This method is suitable for smartphones where the manufacturer allows downgrade via recovery mode (for example, Samsung s Odin, Xiaomi s Mi Flash Tool).

Important: procedure deletes all data from the device, including photos, messages and installed applications. Make a backup copy in advance via Google Drive, Titanium Backup or Swift Backup (root access required).

Action algorithm:

  1. Download official firmware for your model from the manufacturer's website:
  2. Unzip the firmware file (usually this .tar.md5, .tgz or .zip).
  3. Install the app for firmware:
    • Samsung: Odin3 (version 3.14.4 for new devices).
    • Xiaomi: Mi Flash Tool.
    • Google Pixel: fastboot from Platform Tools.
  4. Turn the smartphone into firmware mode:
    • Samsung: turn off the device, press Volume Down + Power, then Volume Up to confirm.
    • Xiaomi/Google: Volume Down + Power (mode Fastboot).
  • Connect the smartphone to the PC and follow the app instructions to install the firmware.
  • Manufacturer Tool Command/Action Notes
    Samsung Odin3 Add files to slots: BL, AP, CP, CSC (select HOME_CSC to save data) Does not work on devices with Knox 0x1 (warranty will expire)
    Xiaomi Mi Flash Tool Select the folder with the firmware, press Refresh, then Flash For global versions (MIUI Global) use firmware marked Global

    fastboot flash radio [file].img

    fastboot flash --slot=all [image].zip

    Requires unlocked bootloader (fastboot flashing unlock)
    โš ๏ธ Attention: On devices Samsung with One UI 5.0+ (based on Android 13/14) downgrade via Odin may lead to activation RPMB-locking if the firmware version is lower than the current one. This will make the phone unusable ("brick") Before updating the firmware, check the compatibility of the versions on the forums. bootloader. This will make the phone unusable ("brick"). Before installing the firmware, check the compatibility of versions on the forums XDA Developers.

    If after firmware, the smartphone is stuck on the logo, try resetting the cache: in recovery mode (Volume Up + Power) select Wipe Cache Partition.

    Method 4: Using TWRP and custom firmware (advanced)

    If the official methods did not work and the warranty is no longer valid, you can resort to custom recovery (TWRP) and alternative firmware. This method is suitable for enthusiasts who are willing to risk stability for the sake of flexibility.

    Advantages of the method:

    • ๐Ÿ”ง Ability to install any version of Android (within the device support).
    • ๐Ÿ› ๏ธ Access to root access and system modifications.
    • ๐Ÿ”„ Easy rollback through backups Nandroid.

    Disadvantages:

    • ๐Ÿšซ Loss guarantees and opportunities OTA updates.
    • ๐Ÿ”’ Risk brika if there is an error in the firmware.
    • ๐Ÿ›ก๏ธ Problems with SafetyNet (banking applications will not work, Google Pay etc.).

    Step-by-step guide:

    1. Unlock bootloader:
      • For Xiaomi: get permission through Mi Unlock Tool (may take up to 720 hours of waiting).
      • For Google Pixel or other brands:
        fastboot flashing unlock
    2. Install TWRP:
      fastboot flash recovery twrp-3.7.0_9-0-lavender.img

      (replace lavender with your device code, for example, davinci for Redmi K20 Pro).

    3. Download the required firmware:
      • Official stock (for example, with XDA).
      • Custom (LineageOS, Pixel Experience, HavocOS).
  • Boot into TWRP (Volume Up + Power), make a backup (Backup โ†’ Select Partitions) and flash the firmware (Install โ†’ Select ZIP).
  • Clear the cache (Wipe โ†’ Dalvik / ART Cache) and reboot.
  • To bypass SafetyNet after installation custom firmware, use modules Magisk:

    • Universal SafetyNet Fix (hides the status of the unlocked bootloader).
    • MagiskHide Props Config (changes device fingerprints for banking applications).
    ๐Ÿ’ก

    Custom firmware is the only way to return the old version of Android to devices with a blocked downgrade (for example, Samsung Exynos or Google Pixel 6+).

    What to do if nothing helps

    If all methods were useless and the device is still unstable, consider the following options:

    • ๐Ÿ”„ Waiting for patch: manufacturers often release โ€œhotโ€ fixes for critical bugs within 1-2 weeks after a major update. Check the updates section every 3-4 days.
    • ๐Ÿ“ฑ Changing launcher: If the problem is in the interface, install an alternative launcher (Nova Launcher, Lawnchair) or theme.
    • ๐Ÿ”ง Disabling problematic functions: for example, if bugs are related to Digital Wellbeing or Google Discover, disable them in the settings.
    • ๐Ÿ› ๏ธ Contacting the service: if the device is under warranty, describe the problem as โ€œoccurring on its own after the updateโ€ - some service centers agree to rollback according to internal instructions.

    If the smartphone has turned into a โ€œbrickโ€ (brick) after an unsuccessful downgrade:

    • Try emergency firmware via EDL mode (for Qualcommdevices) or Download Mode (for Samsung).
    • Refer to specialized forums (XDA, 4PDA) - they often post instructions for โ€œreanimationโ€ for specific models.
    • For devices with chipsets Mediatek a tool can help SP Flash Tool (but requires a file authentication from the manufacturer).
    โš ๏ธ Attention: Starting with Android 12, some manufacturers (for example, Samsung and OnePlus) have implemented a mechanism "Anti-Rollback", which permanently blocks downgrading below a certain version. An attempt to bypass this restriction will lead to irreversible brick. Before any manipulations, check the list of supported versions for your model on official resources.

    FAQ: Frequently asked questions about uninstalling updates

    Is it possible to remove an update without losing data?

    Yes, but only if the update is installed as a separate package (method with ADB). If the firmware is installed on the system partition, you will have to do a reset or reflash, which will delete user data. Always make a backup via adb backup or third-party utilities like Swift Backup (requires root).

    Why does the smartphone not turn on after a rollback?

    This is a typical symptom incompatibility between bootloader and firmware versions. For example, if you flashed Android 11 over Android 12 bootloader on Samsung. Solution: flash the full set of files (BL, AP, CP, CSC) via Odin or return the current version Android.

    How do I know if downgrade is blocked on my device?

    Check availability flag anti-rollback:

    1. Install the application DevCheck from Play Market.
    2. Look at the section Hardware โ†’ Bootloader.
    3. If there is a line Anti-Rollback: Yes or RPMB: Locked, downgrade prohibited.

    Alternative: try flashing the old firmware via Odin/Fastboot - if an error like SW REV CHECK FAILappears, then a rollback is impossible.

    Will Google Pay work after a rollback?

    If you used TWRP or unlocked bootloader, Google Pay it will stop working due to triggering SafetyNet. Solutions:

    • Install Magisk and modules Universal SafetyNet Fix + MagiskHide Props Config.
    • Use alternatives: Samsung Pay (on devices Samsung), Garmin Pay or virtual cards (Revolut, Curve).

    On stock firmware without modifications Google Pay will work.

    Is it possible to roll back the update to Android Go?

    On devices with Android Go (for example, Nokia 1, Samsung Galaxy J2 Core), the rollback options are extremely limited. Manufacturers rarely provide archives of old firmware, and custom recovery (TWRP) is often not supported due to weak hardware. hope that the system will return to the original version. Success is not guaranteed.
