Upgrade Firmware for OnePlus Ace 3

Tue, 06 May 2025 00:00:00 +0800

My OnePlus Ace 3 runs on PixelOS, which doesn’t include the firmware, so I need to upgrade the firmware by myself.

Firmware is installed via fastboot and fastbootd, so we need to test them:

My phone runs on PixelOS_aston-15.0-20250424 with PJE110_15.0.0.500 firmware, and I want to upgrade the firmware to PJE110_15.0.0.701.

Installation steps:

Press the volume-down button and power button to enter fastboot.
Download the firmware from this link. I will download PJE110_15.0.0.701. Extract the file.
Run install_images.sh on Linux/macOS, and install_images.bat on Windows.
