Updated Android and regretted it? How to roll back the firmware - safely and without risks

Have you installed a fresh Android update, but your smartphone started to slow down, discharged in an hour, or stopped running your favorite applications altogether? The situation is familiar to many - manufacturers do not always test firmware on all models, and beta versions may even contain critical errors. Fortunately, it is possible to return the old version of Android, but there are nuances here: rolling back the update through standard settings will not always be possible, and in some cases you will have to sacrifice data.

In this article we will look at all current methods of rolling back an update —from a simple reset to manual firmware via fastboot or ODIN. You will learn what methods work on Samsung, Xiaomi, Google Pixel and other brands, how to save photos and contacts before rolling back, and what to do if your smartphone does not turn on after an unsuccessful update. And also - a table of compatibility of methods with popular models and answers to frequently asked questions.

Important: the rollback procedure depends on the Android version, device model and even firmware region. If you are not sure of your actions, it is better to contact a service center - incorrect manipulations can turn your smartphone into a “brick.”

1. Is it possible to roll back an Android update through settings?

Unfortunately, in most cases it is impossible to return the previous version of Android through the settings menu. Manufacturers intentionally block this feature to prevent users from downgrading to outdated (and potentially vulnerable) firmware. However, there are two exceptions:

• 🔄 The update was installed less than 24 hours ago - some smartphones (for example, Google Pixel) allow you to cancel the installation of the update within 24 hours. To do this, go to Settings → System → System update and click “Cancel update” (if the button is active).
• 📱 Android Beta —if you participated in the beta testing app (for example, Android 15 Beta), you can exit it and return to stable firmware. To do this, go to Settings → Google → Android Beta app and click "Exit".

On devices Samsung, Xiaomi, OnePlus and most other brands, rollback buttons not in the settings. The only “legal” way is to reset your smartphone to factory settings, but this does not guarantee a return to the previous version of Android (most often the same firmware will be installed, but with clean settings).

⚠️ Attention: If you see a button in the settings “Cancel update”, but it is inactive - do not try to activate it through ADB or third-party utilities. This can lead to a bootloader failure and complete loss of device functionality.

2. Resetting to factory settings: does it work?

Resetting to factory settings (Settings → System → Reset → Delete all data) is the first method recommended by support. But there is a catch here:

• ✅ If the update was “over the air” (OTA) —a reset will return the same version of Android, but with clean settings. The previous firmware will not be restored.
• ❌ If the update was installed via fastboot or ODIN —a reset will not help either, since the firmware is written to the system partition.
• 🔄 On some devices Xiaomi and Realme a reset may offer a choice of firmware version (if a backup of the old version is saved in the device's memory). But this only works with manual updating via Mi Flash Tool or Realme Flash Tool.

If you still decide to try a reset, be sure to back up your data. To do this:

Synchronize contacts with your Google account

Copy photos and videos to a PC or cloud

Export SMS through the app (for example, SMS Backup & Restore)

Record a list of installed applications (you can via adb shell pm list packages)

Save passwords from the browser (if you do not use Google Password Manager)

-->

After the reset, check the Android version in Settings → About phone. If it has not changed, proceed to more radical methods.

3. downgrading the Android version via fastboot (for advanced)

If the reset did not help, and there is no rollback option in the settings, you will have to flash the old version manually. This method is suitable for most smartphones with Qualcomm Snapdragon (for example, Google Pixel, OnePlus, Xiaomi with processors Snapdragon). Exynos or Mediatek (many Samsung and Redmi) you will need other tools - more on that in the next section.

What you will need:

• 🖥️ A computer with Windows/Linux/macOS and installed drivers. etc.). ADB And Fastboot.
• 🔌 USB cable (preferably original).
• 📁 Firmware (factory image) for your model - download only from official sources (Google, Xiaomi, Samsung etc.).
• 🔧 Unlocked bootloader (bootloader). On most smartphones it is locked by default.

Step-by-step guide:

1. Unlock the bootloader (instructions for your model).
2. Download the archive with the firmware and unzip it to the folder with fastboot.
3. Connect the smartphone to the PC in fastboot (turn off the device, then press Volume down + Power).
4. Open the command line in the folder with the firmware and run:

   fastboot flash bootloader [bootloader_filename].img
   fastboot reboot-bootloader
   fastboot flash radio [radio_filename].img
   fastboot reboot-bootloader
   fastboot flash --slot=all [other firmware_files]

5. After completion, enter fastboot reboot.

What happens if you flash the wrong version?

Incompatible firmware can lead to:

- Endless loading (bootloop)

- Loss of IMEI and network

- Camera failure or sensors

- Complete inoperability of the device ("brick")

In this case, you can restore the smartphone only through a service center or specialized boxes (for example, UFi or EasyJTAG).

⚠️ Attention: On devices c Dynamic Partition (Android 10+) command fastboot flash all may not work. In this case, use fastboot update [archive_name].zip.

4. Rollback firmware on Samsung via ODIN

Device Samsung (series Galaxy S, Note, A) require a special approach. Here, instead of fastboot a utility is used ODIN, and the firmware is downloaded in the format .tar.md5.

Preparation:

1. Download ODIN (version 3.14.4 or later) and firmware for your model from the website Sammobile or Frija.
2. Install drivers Samsung USB Driver.
3. Enable Mode developer (click on “Build number” 7 times in Settings → About phone) and activate USB debugging.

Firmware via ODIN:

1. Turn off the smartphone and put it in mode Download Mode (press Volume down + Bixby + Power).
2. Connect the device to the PC and run ODIN. A message should appear in the log Added!.
3. In the field AP select the firmware file (for example, AP_[model]_[version].tar.md5).
4. Press Start and wait for completion (do not disconnect the cable!).

Samsung model	Supported rollback method	Risk of data loss
Galaxy S22/S23	ODIN (only for the same version of Android)	High (full reset)
Galaxy A52/A53	ODIN or Smart Switch (if backup is available)	Medium (you can save data)
Galaxy Note 20	ODIN with disabling VBMeta	High (possible loss of IMEI)

5. How to roll back the update on Xiaomi, Redmi and POCO

Smartphones Xiaomi allow you to roll back to the previous version MIUI, but with reservations:

• 🔒 Locked bootloader — rollback is possible only within one version of Android (for example, from MIUI 14 to MIUI 13, but both are based on Android 13).
• 🔓 Unlocked bootloader —you can flash any compatible firmware, but the risk of being “bricked” is higher.
• 📦 Local backup —if you updated via Mi Flash Tool, in The device memory may have saved a file update.zip with a previous version.

Instructions for an unlocked bootloader:

1. Download the desired version MIUI from the website en.miui.com (choose Fastboot or Recovery depending on the method).
2. For Fastbootfirmware use Mi Flash Tool:

   1. Connect your smartphone in mode Fastboot (Volume down + Power).
   2. In Mi Flash Tool select the folder with the firmware and press Refresh.
   3. Press Flash and wait for completion.

3. For Recoveryfirmware:

   1. Rename the file to update.zip and place it in the root of memory.
   2. Go to Recovery (Volume up + Power).
   3. Select Install update.zip.

⚠️ Attention: On devices Xiaomi s Anti-Rollback Protection (for example, Redmi Note 10 Pro, POCO F3), rolling back to a version older than the one specified in the protection will lead to irreversible bootloader lock. Check the list of supported versions on the forum XDA Developers before flashing the firmware.

6. What to do if after a rollback the smartphone does not turn on?

If after trying to rollback the device gets stuck on the logo, reboots in a loop or does not respond to buttons - do not panic. In 80% of cases, the problem can be solved without a service center.

Recovery methods:

• 🔄 Hard reset —press Volume up + Power for 10–15 seconds to force the device to turn off. Then try to go to Recovery Mode and do Wipe data.
• 🖥️ Firmware via EDL Mode - if the smartphone does not respond, but is detected by the PC as Qualcomm HS-USB QDLoader 9008, it can be flashed through emergency mode using Mi Flash Tool or QFil.
• 🔧 Recovery via Test Point —on some models (for example, Redmi Note 8 Pro) to exit in EDL you need to close contacts on the board. Look for instructions for your model.

If nothing helps, and only the charging indicator lights up on the screen, the bootloader may be damaged. In this case, only flashing through specialized boxes (UFi, EasyJTAG) in a service center will help.

💡

Never flash a smartphone with a low battery (less than 30%). If the device turns off during the process, it will be extremely difficult to restore it.

7. How to avoid problems with future updates?

To avoid having to rollback, follow these rules:

• 📵 Do not install beta versions to the main device. For testing, use a spare smartphone.
• 🔍 Check reviews about the new update on the forums (4PDA, XDA, Reddit) before installation.
• ⏳ Wait 1-2 weeks after the update is released - for this time the main bugs will be revealed.
• 📥 Create backups before updating (for example, through TWRP or adb backup).
• 🔒 Block automatic updates in the settings (Settings → System → System update → Settings → Auto-update).

If you often encounter problems after updates, consider installing custom firmware (for example, LineageOS or Pixel Experience). They are updated less frequently and are usually more stable than stock firmware from manufacturers.

FAQ: Frequently asked questions about Android rollback

Is it possible to roll back an update without losing data?

Theoretically yes, but in practice it is almost impossible. Even if you flash an older version of Android without resetting, many applications (for example WhatsApp, banking clients) will require re-authorization, and some data may be damaged due to incompatible versions. We recommend that you always make a backup before rolling back.

Why does the mobile network or Wi-Fi not work after a rollback?

This is a typical problem when flashing an incompatible version of firmware modem (radio module). Solution:

1. Flash separately the file modem.img or NON-HLOS.bin from the original firmware.
2. Check the IMEI using the code *#06#. If it is missing, restore it using ChimeraTool or Maui META.

How to roll back an update on Android Go or devices with low memory?

On budget smartphones (for example, Nokia 1, Samsung Galaxy J2 Core), rollback is complicated due to limited memory. Options:

• Use ADB Sideload for flashing without loading the file into the device memory.
• Flash only system partitions (system, boot), leaving userdata untouched.
• Contact the service - an independent rollback on such devices is fraught with errors.

What to do if the manufacturer has blocked the rollback?

Some brands (for example, Huawei, Oppo) block downgrading the firmware version at the bootloader level. The only way to get around this is:

• Through exploits (for example, DirtyCOW for older versions of Android).
• Using specialized boxes (UFi, Z3X).
• By replacing the motherboard (as a last resort).

On devices Huawei with Kirinprocessors, rollback is often impossible without an authorized account HiSuite.

Is it possible to roll back an update on a smartphone with root access?

Yes, but this does not provide any special advantages. On the contrary, the presence root can complicate the process, since:

• Many firmwares refuse to be installed on devices with a modified bootpartition.
• You will have to manually remove Magisk or other modifications before rollback.
• The probability is bootloop higher due to kernel conflicts.

Recommendation: before rolling back, delete root via Magisk Manager (Uninstall → Complete Uninstall).
