This guide assumes you have downloaded the correct .pkg or .bin file and the appropriate flashing tool (usually SP Flash Tool or QFil for Qualcomm-based devices, which the MW40V typically uses).
Before making any changes, you need to know your current firmware build.
Let me know the details, and I’ll give you a step-by-step solution tailored to your situation.
If your MW40V does not respond at all after flashing new firmware, do a : Alcatel Mw40v Firmware
