How to install a ZTE SD-card software package

Before you start

• Use the package for your exact model and market (the package name shows them, for example …_EEU_… for Eastern Europe).
• Charge above 50% and back up your data. Repairing from recovery can erase the phone.
• You need a microSD card formatted as FAT32, or the phone's internal storage on models without a card slot.

Steps

1. Unzip the download on the computer if it contains a folder; inside is a file named update.zip (sometimes with an instructions PDF). Don't unzip update.zip itself.
2. Copy update.zip to the top level of the SD card (or the phone's storage).
3. On the phone open Settings → System → System updates (or About phone → System update) and choose SD card update / Local update. Confirm and wait.

Phone that won't start

1. Turn it off. Hold Volume Up + Power until the recovery menu appears.
2. Choose Apply update from SD card (or from phone storage) and select update.zip. Use the volume keys to move and Power to confirm.
3. When it finishes, choose Reboot system now.

If something goes wrong

• “Installation aborted” or a signature error: the package is for another model or market.
• The file isn't listed: check that it is named update.zip and sits in the top level of the card.
