Please advice ... firmware for LH-20A1P

Hi, i just got my LH-20A1P. After reading both the benq and liteOn forum regarding the firmware i am very confused which one of them to flash.

My firmware is KL0M. What your expert suggestion ? :bow:

a. 20A1P.KL0N.patched-fb-eos.rar

or cross flash to

b. benq_dw2000_fw6b33.zip

c. DW2000.6B33.patched-fb.rar

Does LH-20A1P have riplock?
