Need help! Stuck at black screen

[Osui818]

I tried to restore custom 4.3.3 cooked from new redsn0w, after restore is done, I got stuck at unable to find .... Green prison.. So I use redsn0w and used just boot. And it work fine, the pineapple logo comes up and got into home screen, but some how Everytime I complete shut off the phone, it goes back to dfu mode, and I have to use Just boot from redsn0w again. Somehow I woke up this morning and the iphone4 is goes to black screen, no apple logo, nothing at all, so I try to use just boot again, it doesn't work, tried to use tiny umbrea to kick out of recovery, doesnt work. I also try to restore stock firware from iTunes, it doesn't work either. Now my phone stuck at black screen with no apple logo, and when I try to charge the phone, it doesn't even charge. Just black screen. It's there anyway I can get it fix?

Thank you

iPhone 4 4.3.3 GSM

First, plug it into itunes powered on. Then try holding both the power and home buttons for 15 seconds, then release ONLY the power button while still holding the home button until you hear the USB sound on your computer. Keep in mind that this is a restore trick that is basically a last resort because you have to restore and update.

Hope this helps!

My computer does detect my phone, and I did try to restore from iTunes, it just doesn't work. The phone still black screen while doing restore, after restore done it still black screen. (after I restore, I connect the phone to pc again, iTunes still say my phone is in restore mode, I tried so many times already, doesn't help)
