Based on the stock Sony 19.1.1.C.0.56 firmware, this ROM is for users who don't want to stray too far from the original Sony experience but want better performance.

Before flashing any custom ROM, you must ensure your device is prepared: Unlock the Bootloader

: This is the most critical step. Note that unlocking the bootloader will void your warranty and may delete DRM keys used for proprietary Sony camera enhancements.
