There are four ways ZTE update:
- Using recovery (to update installed OS)
- Using Fastboot (to recover ZTE with Qualcomm SOC)
- Using Research Download (to recover ZTE with Spreadtrum SOC)
- Using SP Flash Tool (to recover ZTE with MTK SOC)
If you want to install a ZTE update using recovery – download the official update, reboot your phone or tablet into recovery mode and click “Install update from SD card”.
