Newbie question about unlocking

I bought a debranded w580i from ebay and I updated it using SE Pc Suite. It turned to orange network(i think) and the cid went to 52 to 53 and it got locked. So I went to a phone store to unlock the phone for me then after I got the phone unlocked, I debranded it using this firmware:
W580_R8BE001_MAIN_GENERIC_LA_RED53.mbn
W580_R8BE001_FS_AMERICA_1_RED53.fbn
HB1-06_Gen_CDA102568_106_R8A_GENERIC_AMERICA_1

Unfortunately, it got locked again. If I go back to the phone store to unlock the phone again, will it go back to orange network or will it stay debranded?

I would really appreciate if someone can answer my question :)

it will stay debranded

BTW, which accoustic driver is best for my phone? I've searched the customizing firmware section and I don't really know which one is the best. Sorry for getting off topic.

The brazucas are the better ones

If you have cid 53, the unique way to follow, is use Far+Jd Flasher, you can found it here

It was only unlocked with a patch, after the update the patch is away :( The CID changed to CID53 and now you can not unlock your phone for free...
