Updating firmware and unbricking your A30

We have taken great care to ensure that the Firmware Updater App is safe to use, please use caution when using it and follow all written instructions carefully.

We are not responsible for damage to your device. You must use spruce and its features at your own risk.

Updating Firmware

  • Note for 3.0.0 and higher:

There is an automatic App for updating your firmware. If you see this in your App list it means you need to update it. Follow the prompts and you will be done before you know it!

Firmware Updater App

Requires Spruce v3.0.0 & Above

Starting with spruce v3.0.0 we are now include a firmware updater app that will detect if you aren't on the latest firmware. You'll know you should update your firmware you see A Firmware Update Available alongside your other apps in the Apps section.

Running this will give you instructions to prepare for the firmware update and automatically begin the process for you. It is VERY important that your device needs to be plugged in for the Miyoo A30 to run the firmware update. Failure to follow the firmware updating instructions can lead to a bricked device.

Manual Firmware Updating

  1. Download the Firmware.

  2. Format a spare microSD card to FAT32.

  3. Copy+Paste the Firmware onto the microSD card.

  4. Eject the card and insert it into your A30.

  5. Plug it into a charging brick, NOT A COMPUTER.

  6. Turn it ON by holding the power button (there will be a little Rocket Ship and a loading bar) and wait for it to finish. It will turn OFF on its own.

  7. Eject and set aside the firmware microSD card and reinsert your spruce card into your A30.

Unbricking an A30

  1. Download and Extract the Unbricker Image.

  2. Using Rufus, flash the Unbricker as a bootable image onto a fresh microSD card formatting it to FAT32.

  3. Eject your card and insert it into your A30.

  4. Plug your A30 into a charger and power it on. The Miyoo boot logo will appear and then get fuzzy side to side slowly covering the entire screen. It is totally normal, it looks scary. DO NOT POWER IT OFF AT ANY POINT DURING THIS PROCESS. It will eventually turn itself off.

  1. Power on the A30.

  2. Install spruce (or reinsert your old spruce card) and update the Firmware (version 3.0.0 and above have a built in firmware updater app).

Having issues with your microSD card?

Here's how to fix it!

Try this Formatting tool on "Quick" mode. Afterwards format to FAT32 as you would normally and install spruce. It's working like MAGIC getting seemingly dead SD cards working again on the A30!
