Ok, finally I did solve it.
0. I have removed two Sims (Telia was primary, Bitė second). Inserted only Bitė as primary
1. Factory reset
2. Deleted cache via recovery.
3. Again factory reset via recovery
4. Downloaded official baltic ROM from sam...
Tried flashing and starting fresh... still doesn't work. I give up, if it still doesn't work after next OTA I'll take the phone for service. Thanks for the tips though.
Change sim card with different operator for the first boot...
I dont think it is software, because I tried factory reset and it did not help.. Of course, when I get the results I will share them here.
market keeps crashing, wifi doesnt work too
update: doesnt find SD card, camera also doesnt work(cant shoot cuz theres no SD and a view is kinda black and white)...
enough for me.
