LG WebOS TV problem: Log in & App store

Hi...
I bought a 42 inch LG LB65 smart 3d tv from dubai, UAE & brought to my home country Bangladesh.
But now I cant log in to LG app store. Even youtube app is missing after the tv automatically upgraded to 4.3X.XX firmware version recently.

Then what will I do if I cant use the apps in a smart tv with webOS?

If you have any idea about any firmware, country unlocking, tweaking can solve this issue, then pls PLS let me know.
