They are probably the most customizable skins out there that any OEM has to offer. And this is where things become to go south for some. The reason for that is not everyone is a fan of such tweaks and customizations, especially when it comes to the all-important OS. A few years back, users didn’t have much say in that. However, all that changed with the initiation of the Mi A series. These were the set of Android One devices from Xiaomi that managed to incorporate features of both sides. To begin with, you would be getting the clean OS experience without any massive customizations. Furthermore Android One also guaranteed timely OS upgrades. Then on the other side, the devices were still manufactured by Xiaomi hence the value for money stood as it is. Further add to the fact that it was (and still is) among the most active player in custom development, and one couldn’t have asked for more. However as you might be aware, these tweaks might sometimes have negative consequences as well. If not done correctly, your device might end up in a bootloop, soft brick, or worse, a hard brick. But even if that happens, there is a handy way out. You could easily unbrick your Mi A1 device via Fastboot Commands. And in this guide, we will show you how to do just that. So without further ado, let’s get started.

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 Mi A1 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 Mi A1) 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 Mi A1 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 y 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 Mi A1 Fastboot ROM
Next up, download the Fastboot ROM for your device. As for this guide, I am using the Mi A1 (tissot) Global Stable Fastboot V10.0.24.0.PDHMIXM. 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].

Now that you have got hold of the required firmware file, proceed ahead to the next step to unbrick Mi A1 via Fastboot Commands.
STEP 3: Move Mi A1 Fastboot ROM Files to ADB Folder

STEP 5: Flash Firmware via Fastboot Commands to Unbrick Mi A1
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 Mi A1 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. Furthermore, right before we use the command to boot your device to the OS (fastboot reboot), we would be setting Partition A as the active partition (via fastboot set_active a). This is because the actual system fule is being flashed to partition A (fastboot flash system_a system.img). On the other hand, we are just flashing a dummy system file to partition B (fastboot flash system_b system_other.img). So when your device reboots, it will be on the A slot/partition. Just thought of sharing this information as it might come in useful to some of our readers. With that said, let’s turn our attention towards the fastboot commands to unbrick your Mi A1. Once you have successfully executed all the above commands, your device will reboot to the OS. And with this, we conclude the guide on how to unbrick Mi A1 via Fastboot Commands. The best part about this tutorial is the fact that it doesn’t require any Mi A1 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.
