[alirpg]

hello everybody this my first post sorry
the probleme with my iphone 16gb white is
when i plug it into my pc or the wallcharger it stucks on the apple logo
and after sometime the logo goes out and nothing. and if i remove it it goes off.
the probleme is my power buttton is not working anymore i would try to open it and fix it to enter dfu mode (and my phone doesn't get detected) waiting for your answer before trying something (and there is no more warranty) (it enter recovery mode but always not detected). plz it's 2 week that it's stuck thank you.

I'm assuming this is a 3g/3gs .You'll definitely need to put the phone into DFU mode to fix that problem. Fixing the power button is not easy, since the button ribbon cable is a difficult repair. If you're going to be performing that repair, then I'd suggest also replacing your back housing, since the entire iPhone would be disassembled when replacing that ribbon
