[BL602] Crashes with Flag12 turned on

[arhi3a]

Describe the bug MagicHome device crashes after reboot within seconds with Flag 12 - [LED] Remember LED driver state (RGBCW, enable, brightness, temperature) turned on. One particular danger I find with this bug is that after the crash device is setting all RGB leds to 100% brightness no matter the previous state of Toggle.
