LG G2 VS980 not booting, system folder permission is changed accidentally
My LG G2 VS980 phone was rooted by myself. It was a factory unlocked phone. Then using Root Browser by JRummy apps i have removed some system apps and just for a try i have changed the permission settings of system app folder to ro. Then on reboot my phone was stuck, it turns ON and after LG and Verizon logo, says "unfortunately, phone has stopped" and i could see some basic apps such as file manager, calculator etc. but i cannot use the phone at all. It is stuck. How to get back to the original factory unlocked condition? Any ideas plz!
