[AC Question]

Hey...
My galaxy s duos worked pretty fine on a custom rom but a few days earlier some problem occured and I formatted and cleaned everything on it (cache dalvik memory emmc and other things).Using cwm .
I thought of flashing a new rom. The problem is that now my phone is stuck on the logo screen with that yellow ! sign..
also it does not go into recovery mode.using the vol power home button
it does go into download mode
also when i plug it to charge it just shows the battery icon that shows before the mobile is just about to charge..
Can it be solved??
