+# Flashing with fwupd
+
+#### **Requirements:**
+
+* fwupd version 1.5.6 or later
+* The battery must be charged to at least 30%
+* The charger must be connected (either USB-C or DC Jack)
+* BIOS Lock must be disabled
+* Supported Linux distribution (Ubuntu 20.04 +, Linux Mint 20.1 + elementaryOS 6 +, Manjaro 21+)
+
+**fwupd 1.5.6 or later**
+To check the version of **fwupd** you have installed, open a terminal window and enter the below command:
+
+```
+fwupdmgr --version
+```
+
+This will show the version number. **1.5.6** or greater will work.
+![fwupd version](fwupdVersion.png)
+On Ubuntu 20.04, Ubuntu 20.10, Linux Mint 20.1 and elementaryOS 6, fwupd 1.5.6 can be installed from our PPA with the below terminal commands:
+
+```
+sudo add-apt-repository ppa:starlabs/ppa
+sudo apt update
+sudo apt install fwupd
+```
+
+On Manjaro:
+
+```
+sudo pacman -Sy fwupd-git flashrom-starlabs
+```
+
+Instructions for other distributions will be added once fwupd 1.5.6 is available. If you are not using one of the distributions listed above, it is possible to install coreboot using a Live USB.
+
+**Disable BIOS Lock**
+BIOS Lock must be disabled when switching from the standard AMI (American Megatrends Inc.) firmware to coreboot. To disable BIOS Lock:
+
+1\. Start with your LabTop turned off\. Turn it on whilst holding the **F2** key to access the BIOS settings.
+2\. When the BIOS settings load, use the arrow keys to navigate to the **Advanced** tab\. Here you will see **BIOS Lock**\.
+3\. Press `Enter` to change this setting from **Enabled** to **Disabled**
+
+![Disable BIOS Lock](BiosLock.jpg)
+
+4\. Next, press the `F10` key to **Save & Exit** and then `Enter` to confirm.
+
+#### **Switching Branch**
+
+Switching branch refers to changing from AMI firmware to coreboot, or vice versa.
+
+First, check for new firmware files with the below terminal command:
+
+```
+fwupdmgr refresh --force
+```
+
+Then, to change branch, enter the below terminal command:
+
+```
+fwupdmgr switch-branch
+```
+
+You can then select which branch you would like to use, by typing in the corresponding number:
+![Switch Branch](SwitchBranch.png)
+You will be prompted to confirm, press `y` to continue or `n` to cancel.
+
+Once the switch has been completed, you will be prompted to restart.
+
+The next reboot can take up to **5 minutes,** do not interrupt this process or disconnect the charger. Once the reboot is complete, that's it - you'll continue to receive updates for whichever branch you are using.
+
+You can switch branch at any time.
