3310&3350 Flash Possible But Doesn't Sw On
 

3310 & 3350 flashing is possible but doesn"t sw on tried change ccont,cobba,hagar any solution kindly help

thanks

Is it 3310 for sure? This problem is often caused by mistake beetween 3310 and 3330 - flash accepted, but no power off. Try to flash it as 3330, maybe this'll help. Another thing (if hardware fails) is to change G502, it may be broken, nor I'm not sure would it take flash... Are you using full flash w. eeprom?
