I have a samsung galaxy young gt- s6312 and i recently rooted it successfully with cwm custom rom. Then i was trying to change my default font and suddenly it froze and was not responding,so i tried to reboot it with the power key but it wasn't rebooting as it should. So i removed the battery and powered it on again . It powered on and was rebooting normally but it stuck at the "SAMSUNG" screen forever. I tried rebooting many times but it didnt reboot anymore. So i went to the recovery mode and did a hard reset ,,and restarted the device again,but it was the same case no change at all.So in the recovery mode i formatted my system , cache,......Now tried to reboot, now it came to the "SAMSUNG GALAXY YOUNG GT-S6312" screen and froze forever.
I want to reinstall the stock firmware and the android os itself to the default mode.
