Prerequisites

A USB flash drive formatted to FAT32.
A monitor and a USB keyboard connected to your Olares One.
The EC or BIOS update package, downloaded to your computer.

Update the EC firmware

Extract the downloaded EC update package.
Copy the resulting folders (e.g., AGBOX4_EC_01_02 and EFI) to the root directory of your USB drive.
Connect the USB drive to your Olares One.
Power on the device or restart it if it is already running.
When the Olares logo appears, immediately press and hold the F7 key to enter the boot menu.
Select your USB drive from the list, and then press Enter.
When the EFI startup countdown screen appears (Press ESC in 5 seconds to skip startup.nsh), immediately press Enter to access the command shell.
Enter the following command, and then press Enter to navigate to the EC directory:
bash
```
cd AGBOX4_EC_01_02
```
Enter the following command, and then press Enter to execute the update tool:
bash
```
ECFlashTool.efi AGBOX4_EC_01_02.bin
```
The system will display the progress as it erases and programs the flash memory. Wait for the update process to complete. Once finished, the device restarts automatically.
When the Olares logo appears, immediately press and hold F7 to enter the boot menu.
Select Enter Setup to access the BIOS.
On the Main tab, verify that the EC FW Version displays 1.02 (or your target version) to confirm the update was successful.

Update the BIOS

Important

Do not disconnect the power supply or turn off the device during the BIOS update process. Doing so might permanently damage the system.

Extract the downloaded BIOS update package.
Copy the resulting folder (e.g., AGBOX4_BIOS_101 and EFI) to the root directory of your USB drive.
Connect the USB drive to your Olares One.
Power on the device or restart it if it is already running.
When the Olares logo appears, immediately press and hold the F7 key to enter the boot menu.
Select your USB drive from the list, and then press Enter.
When the EFI startup countdown screen appears (Press ESC in 5 seconds to skip startup.nsh), immediately press Enter to access the command shell.
Run the following commands one by one to navigate to the AFU directory and start the flash script:
bash
```
cd AGBOX4_BIOS_101
cd AFU
FlashAFU.nsh
```
Wait for the script execution to finish.
The system will automatically reboot and display a blue Flash Update progress screen.
Once the flash update reaches 100%, the ME FW Update starts automatically. Wait for this process to complete.
When the ME FW Update finishes, the system will automatically reboot two times. Wait until the normal olares login prompt appears.
INFO
During the reboot, the system will perform a comprehensive hardware self-test. This process takes approximately 2 to 3 minutes. The screen might remain black during this time.
Verify the BIOS version.
a. Restart Olares One manually.
b. When the Olares logo appears, immediately press and hold F7 to enter the boot menu.
c. Select Enter Setup to access the BIOS.
d. On the Main tab, verify that the System BIOS Version displays 1.01 (or your target version) to confirm the update was successful.
