I have Galaxy core GT I 8262 phone and after I use it for a month it stops charging. I try different charger, charging from pc/laptop but still didn't work. I check my battery and charger with my friends phone and both works. when I use different charger firstly it indicates the charger sign and then it starts software update and says don t unplug USB and downloading but by that time I am not connected to any network. I also use a solution from blog ---> remove battery wait for second and plug charger then power up but no solution ! please help..
