Please help me unlock W580i........PROBLEM

I'm having W580i from At&T and I unlocked it for other network few months ago using the unlock patch technique......usinf the following firmware W580_R8BA024_FS_S_ASIA_LEVAN_RED52.fbn
W580_R8BA024_MAIN_GENERIC_LA_RED52.mbn

Few days back I tried to upgrade my firmware to
W580_R8BE001_FS_S_ASIA_LEVAN_RED52
W580_R8BE001_MAIN_GENERIC_LA_RED52

Firmware upgrade was sucessful but my phone got locked (network) again.I tried to unlock it again through the same process that I used earlier but I could not.

After few attempts I got fedup and though to go back the previous firmware and do the same process with the same files to unlock as earlier.But I could not do that too......

I'm posting the log file of the whole process.Please go through and help me solve my problem............
