Last night I installed SlimSaber Unofficial 4.4.4 rom and was using it with joy. Today the screen suddenly went black and phone started not launching. Galaxy note logo appears, then SlimSaber logo appears suddenly goes black. I tried reinstalling the rom, didn't fix. Tried installing Asylum Rom. Didn't work either. I can't go past the Galaxy Note logo. It just goes black and then nothing. Like the phone is powered off. Can some good fella help me about the situation? Sorry to bother you with such a amateur question. I'm not so knowledged on the situation. Thank you!
