Is your WE V4 refusing to boot, stuck on the logo, showing FRP lock, or slow after an update? Many WE V4 users complain about persistent hang logo, random freezes, failed boot, FRP lock, pattern or pin issues, fastboot mode errors, and even blank display after OTA updates. Such issues are typical for MediaTek MT6739-based devices, often requiring a full system restore.
The official WE V4 firmware (MT6739, SW_V1.5_180515) can fix all these problems — restoring the phone from brick, fixing bootloops, removing FRP/pattern lock, and reviving dead devices for normal use.
