The Vodafone Smart Ultra 6 (P839V55, MSM8939) runs Android 5.1.1 and is praised for solid midrange specs, but suffers many reported problems: bootloop after update, stuck at logo, system lag, random reboots, and dead phones from failed flashes or battery replacements.
Users also mention recurring “no service,” Wi-Fi not working, or device freezing, plus IMEI/network loss after botched firmware attempts. Flashing official firmware (Vodafone_Smart_Ultra_6_P839V55V1.0.0B11_QPST.zip) can repair boot issues, restore a bricked device, and fix system bugs when done correctly with QPST.
