Miyoo Mini Firmware Upgrade Guide

This Miyoo Mini firmware upgrade guide is super important, because your Miyoo Mini or Miyoo Mini Plus could be bricked in the process of upgrading the firmware. Moreover, to use the latest Onion OS version, you need to use the latest firmware for your device. Quite troublesome, right?

It is a frequently asked question in subreddit Miyoo, as people need an official answer for updating or upgrading firmware on their Miyoo Mini Plus. Sadly, it seems the original website lemiyoo.cn is out of reach at the moment, so I hope this guide is clear enough to safely show you the way to upgrade firmware on your Miyoo Mini or Miyoo Mini Plus. I recommend to read this guide before proceeding into my ultimate Miyoo Mini Onion guide.

First, you should select your device. You take the blue pill – the story ends, you wake up in your bed and believe whatever you want to believe. You take the red pill – you stay in Wonderland and I show you how deep the rabbit hole goes.

Miyoo Mini firmware download

With lemiyoo.cn is unable to reach, it is more and more difficult to download the official firmware for the device (it seems its website moved to something named lomiyoo.com, but I don’t know when it will be down). Thankfully, you can grab the latest firmware for your Miyoo Mini device in my guide.

How to update firmware on Miyoo Mini Plus?

With the firmware update available, you can now proceed to the firmware installation part. First, copy the .img firmware file to the root of your microSD card. It is common sense to backup the whole microSD card onto your computer. I also made an ultimate handheld SD card guide so you can have general idea of which SD card you should get.

Then, you should follow these steps, one by one:

  • Turn off the Miyoo Mini or Miyoo Mini Plus device. Make sure you turn it off completely, you can try pressing Power button to check whether it’s on or off. Additionally, make sure that any LEDs of your Miyoo device is turned off.
  • Put the microSD card into your Miyoo Mini or Miyoo Mini Plus.
  • Remove battery.
  • Plus the device into a charger. I recommend to a common 5V/1A charger to avoid any voltage problems, for every retro device. Make sure you don’t accidentally turn on the device, or unplug it during the firmware upgrade process.
  • Now you should wait until the battery icon appears, then it’s safe to unplug the device from charger.
  • Remove the microSD card, and put it back into the computer. Delete the .img firmware file from the microSD card.
  • You can copy backup files and folders you save on computer.

That’s it, if you have any other questions, please find it in my Miyoo Tutorial.
