How to install an OnePlus / OPPO full update (local install)

Before you start

• Match the model number (Settings → About device, for example CPH2449) and the region (EU, IN, GLO, NA, CN). Region packages are not interchangeable.
• Use the same or a newer version — older ones are refused.
• Charge above 50% and back up.
• Download links for some packages are generated on the spot and expire after a few minutes. Start the download right after clicking, and use the checksum to confirm it finished.

Steps

1. Copy the .zip to the top level of internal storage.
2. Older OxygenOS / ColorOS: Settings → System → System updates → ⚙ or ⋮ menu → Local upgrade, then pick the file.
3. OxygenOS 13 and newer, ColorOS 13 and newer: local install is hidden. Install OnePlus’s official Local Update APK (often called OPLocalUpdate), open it, choose the file and tap Install.
4. The phone verifies the file, installs it and restarts.

If something goes wrong

• “Verification failed”: wrong model or region, or an incomplete download. Check the MD5 on the file page.
• The option doesn’t appear: use the Local Update app from step 3.
