MediaTek Device Stuck in Preloader USB VCOM Mode: How to Fix

In this guide, we will show you the steps to fix the issue of the MediaTek device being stuck in the Preloader USB VCOM mode. Recently, I got my hands on a Xiaomi device having a MediaTek chipset and thought of testing the SP Flash Tool on it. I checkmarked all the prerequisites involving the DA, Scatter, and Authentication files, unchecked the Preloader partition, booted the device to BROM Mode, and started the flashing process.

Guess what? The flashing went fine without any hiccups, and I got the Download OK message as well. But this is where things began to go south. After the success message, I waited till eternity for the device to boot to the OS. When that didn’t happen, I pressed the Power key to boot the device. But unfortunately, neither of the two methods managed to boot up my device.

This was really strange as the flashing was successful without any errors whatsoever. At the very most, my device showed flashes of the Poco logo, but that was it [if that’s not happening with your device, not an issue, I’ll show you how to bring up that screen]. So as soon as the device showed the Poco logo, I launched Device Manager, and there was my device shown in Preloader USB VCOM Mode.

I breathed a huge sigh of relief because my PC could atleast identify the device [again, if that’s not the case with you, don’t worry; I’ll show you how to get that job done]. After that, it was just a matter of carrying out a couple of tweaks, and my device was then booted to the OS in all its glory. So, in this guide, I thought of documenting this fix to help you out in case you also get stuck in such a scenario. So without any further ado, let’s get started.

Although you wouldn’t be able to take a backup, we would still warn you that this process will wipe off all the data from your device. 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.

If your device is currently in a bootloop, meaning you can atleast see the Xiaomi/Poco logo even for a couple of seconds, then it’s all fine. But if you are not seeing the logo and your device is currently powered off, then press and hold the Power, Volume Up, and Volume Down keys for a few seconds until you feel a slight vibration.

While this hardware key combination does work across numerous Xiaomi devices, it might not work for all. If your device isn’t responding to this combination, then try out a different one until you see the logo for a few seconds. Once you see the logo, your device will be in a bootloop.

In that case, as soon as the device is powering off during a bootloop, press and hold the Power and Volume Down keys for a few seconds, and your device will straightaway go to the Fastboot Mode [if that didn’t work out, then use the Power and Volume Up keys]. Once you’re in Fastboot Mode, just flash the Fastboot ROM using the Mi Flash Tool , and your device will be up and running.

The common notion [we are looking at you, Gemini] that you cannot use the Mi Flash Tool on MediaTek devices is completely false. You can easily flash the stock firmware and Fastboot ROM on any Xiaomi/Poco/Redmi/Mi device having a MediaTek chipset using the Mi Flash Tool, as we have shown above.
