How to write back CUSTOMIZED_LED ?

I made txt dump before playing with fw, and after some time i found that LED is not working.
I found that before start i had

LED : 0x01
CUSTOMIZED_LED : 33 00 00 00 00 00 00 00 00 00 00 00 00 00 00 
SUSPEND_LED_OFF : 0x00
HW_LED_CFG : 0x00000000

And now i have

LED : 0x01
CUSTOMIZED_LED : n/a
SUSPEND_LED_OFF : 0x00
HW_LED_CFG : 0x00000000

I'm losing CUSTOMIZED_LED. I tried

CUSTOMIZED_LED = 33 00 00 00 00 00 00 00 00 00 00 00 00 00 00
CUSTOMIZED_LED = 33 00
CUSTOMIZED_LED = 0x3300

but no luck
