How to Unbrick Oppo A series via Fastboot Commands

In this comprehensive tutorial, we will show you the steps to unbrick any Oppo A series device via Fastboot Commands. The Chinese OEM has quite a few devices lined up in its budget segment. In this regard, its A-series has managed to grab all the limelight. An impressive specs sheet coupled with the fact that it is light on your pockets has made these devices the crowd’s favorite.

Along the same lines, they are becoming increasingly popular in custom development. While they still have a long way to go compared with its counterpart Xiaomi, they are surely catching up the pace. Once you have unlocked the device’s bootloader, there is a truckload of noteworthy things to try out. These include flashing custom mods, ROMs, and recoveries.

While all these tweaks do tend to add more features to your device, there’s always an element of risk. If you flash the incorrect binary or flash the correct binary to the incorrect slot, then you are inviting trouble. In those cases, your device might end up in a bootloop or bricked state. But fret not. You could still unbrick your Oppo A series device via Fastboot Commands. Follow along for the instructions.

STEP 1: Install Android SDK

install adb platform tools windows

First and foremost, you will have to install the Android SDK Platform Tools on your PC. This is the official ADB and Fastboot binary provided by Google and is the only recommended one. So download it and then extract it to any convenient location on your PC. Doing so will give you the platform-tools folder, which will be used throughout this guide to unbrick the Oppo Find A series via Fastboot Commands.

STEP 2: Boot Device to Fastboot Mode

Since your device is in a bootloop/soft-brick state, you cannot use the adb reboot bootloader command. Hence you will have to opt for the hardware key combinations. Here’s how it could be done:

  1. To begin with, power off your device (if you can’t do so via the Power key then let the battery drain out).
  2. Once it turns off, press and hold the Power and Volume Down keys for a few seconds,
  3. Your device will be booted to Fastboot Mode. Now connect it to the PC via USB cable.

STEP 3: Download Stock Firmware

Next up, you will have to download the stock firmware for your device. You may grab it from Oppo’s official Software Update page. At the time of writing, the stock firmware for some Oppo A series devices isn’t available on that page. So users having those devices would have to download the firmware from any other trustworthy site and then proceed with the below steps to unbrick Oppo A series via Fastboot Commands.

STEP 4: Extract Oppo OZIP Firmware


The firmware that you have downloaded will be in OZIP format. You will have to convert it to ZIP. For that, please refer to our detailed guide: How to Extract OZIP Realme Stock ROM (Firmware).

STEP 5: Download URTool

Download the URTool from GitHub [Credits: XDA Recognized Contributor acervenky] and extract it to any convenient location on your PC. This tool will be used to extract the dat.br files (the system.new.dat.br and vendor.new.dat.br files).

STEP 6: Set up the Working Environment

  1. Once you have extracted the OZIP firmware, you will get the resultant ZIP firmware file.
  2. Extract it using any software of your choice (WinRAR, 7ZIP, etc).
  3. Upon extraction, you shall see the boot.img file. Copy it and transfer it to the platform-tools folder on your PC.
    copy boot.img from ozip
  4. Next up, again go back to the extracted firmware and this time head over to the firmware-update folder.
  5. Copy all the files of that folder and transfer them to the platform-tools folder as well.  The setup is now complete and you may proceed to the next steps to unbrick Oppo A series via Fastboot Commands.

STEP 7: Extract Oppo dat.br Files

  1. You will now have to extract the system.new.dat.br and vendor.new.dat.br files.
  2. Copy-paste the firmware ZIP file that you had got after converting OZIP to ZIP. Then transfer this firmware ZIP file to the URTool folder.

  3. After that, double click on the URTool.bat to launch the tool.
  4. The Tool will now read the file and display the same in the window. Type in the corresponding file number in the window and hit Enter (if there’s only one ZIP file, then it would be 1).
  5. Then select the Extract Android Image option. For that, type in 1 and hit Enter.
  6. Extraction will now begin and could take a few minutes.
  7. Once the extraction is done, the files will be placed under the URTool-master > 01-Project> 1-Sources folder.
  8. Copy the system.img and vendor.img files from there and transfer them to the platform-tools folder.

STEP 8: Unbrick Oppo A series via Fastboot Commands

  1. Before moving ahead, verify that you have the following files in the platform-tools folder: boot.img, system.img, vendor.img, and all the files from the firmware-update folder.
  2. If that is all well and good, then head over to the platform-tools folder, type in CMD in the address bar, and hit Enter. This shall launch the Command Prompt window.
  3. Now type in each of the below commands, one at a time, in this CMD window to flash the Oppo stock firmware (if you get an error while executing a command, skip that command and move over to the next one. Never leave the command screen in between):
    fastboot flash abl abl.img
    fastboot flash aop aop.img
    fastboot flash bluetooth BTFM.img
    fastboot flash boot boot.img
    fastboot flash cmnlib cmnlib.img
    fastboot flash cmnlib64 cmnlib64.img
    fastboot flash devcfg devcfg.img 
    fastboot flash dsp dspso.img

    fastboot flash vbmeta_vendor vbmeta_vendor.img 
    fastboot flash vendor vendor.img 
    fastboot flash xbl xbl.img
    fastboot flash xbl_config xbl_config.img
    fastboot reboot
  4. The last command will boot your device back to the OS and your task stands complete.
