My first time!!! K800i

About 5 days ago i first time had problems with my K800i:a006 I could not open games and aplications and on the net i found that update can help so i do it! I update my phone using SE aplication via USB! When updating finished and i try to turn on phone on the screen apered that SIM card is incorect!!! Last two days i spend reading forums and i found out MY PHONE NETWORKS ARE LOCKED!!! I tried every tutorial that i find on the net, but most of them are old about 1-2 years! Now i need your help :a009 I want to do it for free(don't have enough money right now, and services in my city are to far from my house) my phone firmware is K800_R8BF003_MAIN_GENERIC_WI_RED53!!! Is there chance to downgrade to CID52 and easy unlock it or some other free way to unlock (i don't have original SIM card)! Plss help me, a knew you can do it! PLSSSSS!!! And sry for my bad english!
