How To Flash Stock ROM Using SD Card On ZTE Nubia Smartphones

For many Android tweakers, flashing custom and stock firmware and ROMs on an Android smartphone requires the use of special tools on your PC. What many do not know, however, is that you can flash ROMs and firmware on some smartphones directly from your SD card without needing tools like Skipsoft Android Toolkit or SP Flash Tool on your PC. If you use a ZTE Nubia smartphone, this is a guide on how to flash stock ROM using SD card on ZTE Nubia smartphones.

Flashing the stock ROM of your smartphone is the best thing to do if you run into any problems with the custom software you’ve installed. Also, if you wish to get official OTA updates, enjoy warranty protection on your device, or you brick your smartphone while performing some tweaks (like rooting), you have to flash the stock ROM of the device in question.
