Tags: LG K540 Stock kdz firmware

The latest software for the LG Stylo 2 LGK540 for Cricket is software version K54014b which was released in January 2019.

As Cricket Wireless offers the software update for LG Stylo 2 LGK540 via FOTA only, We can not use LG Bridge to restore the LG K540, and the stock kdz firmware for LG K540 is not available for public download.

Do not worry! Thanks to an LG Stylo 2 LGK540 user at XDA forum, we have got the unmodified stock firmware package for the LG Stylo 2 K540. This package IS NOT a TOT or kdz package. Rather, this package contains untouched partition images (.img) dumped from a working LG Stylo 2 LGK540.
