Bq34z100-G1 Lead Acid optimization cycle problem

Hi,

I'm using BQ34Z100-G1 with a AGM lead acid battery 12V 1.3Ah and 0x0802 chemID.  Here is battery sepcification: http://www.datori.lv/docs/kkjnE . I have problem with optimization cycle. I'm following the steps:

1. Discharge to empty, wait for OCVTAKEN flag set and rest for few  hours. 

2. Send IT Enable command

2. Charge to full (FC bit set), wait for OCVTAKEN flag set and rest for few hours

3. Discharge to empty with ~170mAh current.

4. After few hours OCVTAKEN flag is set, VOK is not cleared and Update Status is still 04.

I have repeated optimization process several times, but without success (Update Staus always stays 04). I'm attaching .gg.csv and .srec file. Can someone look at it and tell me what I'm doing wrong?
