I bought a lg g2 month ago and 2 weeks ago i decided to update the system. There was no option to do it via wi-fi but was on LG PC software so i did via LG PC Suite. When the update was complete i disconnected phone. Unfortunately it bricked on LG logo screen. I found on google solve of the problem by fasboot mode and installed the stock. I was happy, but not for long. After installation I saw that the display does not work as it should. Attached film shows it the best - it's hard to say by words.
And now it's time for my question: How can i fix it? Is it problem with system? When I bought phone, there was installed Android 4.2.2 but after unbrick i couldn't find 4.2.2 system for D802T 32GB. Maybe i should find correct system? Or maybe it's problem with display or/and digitizer and should i take it to repair?
I would like to point out that I do not have the possibility of sending to service on warranty because the phone was imported from China and I do not have a receipt or invoice.
Thank you in advance for your help and I'm sorry for the mistakes in English - I'm Polish.
