How to Unbrick any Oppo Reno Device via Fastboot Commands

In this comprehensive tutorial, we will show you the steps to unbrick all the Oppo Reno series devices via Fastboot Commands. While the Chinese OEM has quite a few series lined up its sleeves, it’s the Reno one that has caught the attention of the masses. It all started with its unique-looking razer fin shark camera design that made it stand out from the crowds.

Apart from that, these devices also behold an impressive feature set, considering the price segment to which they belong. Likewise, they are also quite active in custom development. Right from unlocking the bootloader to flashing custom ROMs and recoveries, there’s a lot to try out. You may also gain administrative privileges by rooting the device via Magisk. However, all these tweaks bring in a few uninvited risks as well.

If you flash an incorrect binary or mess up with any instructions, then there are chances of your device ending up in a bootloop or soft-bricked state. Fortunately, there’s a handy way out. You could easily unbrick your Oppo Reno series device by flashing the stock firmware via Fastboot Commands. And this guide will show you how to do just that. So without further ado, let’s get started.

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.

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 Oppo Reno 5 and 6 series isn’t available on that page. So users having those devices would have to download the firmware from any other trustworthy site.

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.

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).

  8. Copy the system.img and vendor.img files from there and transfer them to the platform-tools folder.

STEP 8: Unbrick Oppo 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 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.
