How to install vivo firmware (local upgrade)

Before you start

• Use the package for your exact model. The product code at the start of the version (for example PD2102F) must match your phone.
• These packages are for phones sold on the open market, not carrier-locked phones.
• Charge above 30% (50% is safer) and back up contacts, messages and photos.

Steps

1. Copy the .zip to the top level of the phone storage — not inside a folder. Don’t unzip it.
2. On the phone open Settings → System update, tap the settings (gear) icon at the top right and choose Local upgrade (on some versions: Install local update).
3. Select the package and tap Install.

Phone that won’t start

1. Turn it off. Hold Volume Up + Power until FASTBOOT mode appears.
2. With the volume keys choose Recovery mode, press Power.
3. Choose Install software → Phone memory (or SD card), select the package and confirm.

If something goes wrong

• “Version is lower than current”: vivo blocks downgrades. Choose a newer package.
• The package isn’t listed: it must be in the top level of storage with the original file name.
