How to Unbrick Redmi Note 9 Pro via Fastboot Commands

In this guide, we will show you the steps to unbrick your Redmi Note 9 Pro device via Fastboot Commands. This offering from Xiaomi has a lot to talk about. The huge 6.67-inch display comes with a top tier octa-core Qualcomm Snapdragon 720G chipset under the hood. This coupled with up to 8GB of RAM and Adreno 618 GPU, and you are guaranteed a powerhouse.

Along the same lines, it comes with a quad rear camera setup. While the wide and ultrawide gives out more than decent clicks but the macro and depth sensors leave a lot to be desired. Then its single selfie camera could record video at 1080p@30. All these features are supported by a 5020 mAh battery that supports 30W Fast Charging. Well, this device also has quite an impressive support in custom development.

There are already quite a few custom binary and mods available for this device. But if you end up with a slight mistake, and your device could result in a bootloop or bricked state. Fortunately, there is still a handy way out to unbrick your Redmi Note 9 Pro device via Fastboot Commands. And in this guide, we will show you how to do just that. Follow along.

Xiaomi and EDL Mode: It’s Complicated!

Recently Xiaomi made a massive change that leads to disastrous consequences for the tech enthusiasts and developers alike. The only ones who would remain unaffected by this decision are the ones who maintain a safe distance from Unlocking Bootloader, Rooting, and Flashing Custom binary. Rest all the users like us who are engrossed in these tweaks are the suffering party. So what really happened?

Well, if you step into custom development, then it opens the gates to the plethora of customization options. From installing a custom recovery like TWRP to getting access to the system partition via Magisk, the possibilities stand endless. Along the same lines, you could flash custom ROMs, Magisk Modules, Substratum Themes, Xposed Frameworks, and the likes. But these tweaks are risky in nature.

If you end up flashing a wrong binary or flash the correct binary to the incorrect slot (for A/B partition devices), then you are inviting trouble. By trouble, we mean the device would end up in a bootloop, soft brick, or worse hard brick. While the first two are usually easy to deal with, it is the latter one that might be concerning for the users.

Fortunately, the devices that have Qualcomm as the underlying chipset comes with EDL Mode or the Emergency Download Mode. You only need to boot your device to EDL and flash the firmware file and your device will be back from dead. Unfortunately, Xiaomi decided to block this EDL mode for the general users.

So only the users who have an authorized Mi Service Centre ID could flash the firmware via Mi Flash Tool in EDL Mode. As for the general users, there does exist a workaround in the form of using the Redmi Note 9 Pro Patched Firehose File (prog_emmc_firehose.mbn) or the prog_firehose_ddr_unbrick.elf file. However, finding both these files is among the most challenging task ever.

With that said, if your Xiaomi device is stuck in bootloop or soft brick mode, there is still a handy way out. You could easily unbrick your Xiaomi device (which in this case is Redmi Note 9 Pro) via Fastboot Commands. We wouldn’t be using any Mi Flash Tool or any other software for that matter. So how will then this task be carried out? Follow along for the detailed instructions.

How to Unbrick Redmi Note 9 Pro via Fastboot Commands

Now that we are done with the explanation part, let’s turn our attention towards the unbrick instructions. As I have already mentioned before, the below instructions are only valid for devices that are soft-bricked or in a boot loop. Furthermore, the process is going to wipe all the data on your device.

So keep this thing in mind before proceeding and take a backup beforehand (if possible by any means). Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing the below steps.

STEP 1: Download Android SDK

To begin with, download and install the Android SDK Platform Tools. This is the official ADB binary file provided by Google and is used to execute ADB and Fastboot Commands.

STEP 2: Download Redmi Note 9 Pro Fastboot ROM

Next up, download the Fastboot ROM for your device. As for this guide, I am using the following ROM file: Redmi Note 9 Pro (curtana) India Stable Fastboot V12.0.2.0.QJWINXM. You are free to try any version of your choice, but it is recommended to try the newer builds only and of your region. Here is how to understand the Xiaomi Fastboot firmware version. [Don’t Miss: How to Flash Xiaomi Fastboot ROM without Mi Flash Tool].

• 12.0.2.0 – Firmware version
• Q – Android version (Q-> Android 10).
• JW – Smartphone model code (JW = Redmi Note 9 Pro)
• IN – Firmware build type (IN for India | MI for Global | EU for Europe)
• XM – Firmware version code​

Now that you have got hold of the required firmware file, proceed ahead to the next step to unbrick Redmi Note 9 Pro via Fastboot Commands.

STEP 3: Move Redmi Note 9 Pro Fastboot ROM Files to ADB Folder

1. To begin with, extract the downloaded firmware file. Once the extraction is complete, you should see the following files:
   
2. So head over to the Images folder and the following files will be present there:
   
3. Select all these files via Ctrl+A shortcut keys and copy them to the platform-tools folder. This is the same folder that you have got after installing the Android SDK.
4. Once done, proceed to the next step to unbrick your Redmi Note 9 Pro device via Fastboot Commands.

STEP 4: Boot Bootloop/Soft Bricked Redmi Note 9 Pro to Fastboot Mode

1. First off, boot your device to the Fastboot Mode. For that, power it off.
2. If you cannot do so (due to your device being stuck in a bootloop) then the only option left is to let the entire battery drain out (remember the good old days when we could easily remove the battery!).
3. Once your device has turned off, press and hold the Volume Down and Power buttons for a few seconds.
4. This will boot your device to Fastboot Mode. You should see the famous Mi Bunny Logo with the Fastboot text underneath it.
   

   

5. Now head over to the platform-tools folder where you have extracted the Fastboot ROM.
6. Go to its address bar, type in CMD, and hit Enter. This will launch the Command Prompt window. Keep this window opened from now on until the end of this guide.

STEP 5: Flash Firmware via Fastboot Commands to Unbrick Redmi Note 9 Pro

Finally, we are down to the most important part of this article. I have shared all the required fastboot commands to flash the stock firmware onto your Redmi Note 9 Pro and unbrick it. To begin with, make sure that your device is connected to the PC via USB in Fastboot Mode. Then head over to the Command Prompt window that is opened inside the platform-tools folder.

Now execute the below commands in this CMD window. I would highly recommend that you execute these commands one at a time, rather than copy-pasting all of them at one go.

The best part about this tutorial is the fact that it doesn’t require any Redmi Note 9 Pro Patched Firehose File (prog_emmc_firehose.mbn) or the prog_firehose_ddr_unbrick.elf file.

Furthermore, we didn’t need to make use of the Mi Flash Tool. With that said, if you have any queries concerning the aforementioned steps, do let us know in the comments section below. We will get back to you with a solution at the earliest.
