Unhappy [Q] Permanently locked LG G2

Yesterday i got my lg g2 from ebay. I spent several hours researching how to root my phone, install custom recovery and a custom rom. Eventually I succeeded. feeling proud of my 'accomplishment' (as it was my first time) i went to bed. only to find out that my phone is permanently locked when trying to unlock it!!! I googled for answers, but I couldnt find one. My LG G2 is D802 int variant. running 4.4.2 with cloudyG3 1.3 ROM. Is there a workaround for this issue? I'd like to emphasise the fact that this phone is PERMANENTLY locked so please dont suggest to buy an unlock code. thank you
