hi everyone. 
so, i was working on an old iphone 3GS ( i just changed the battery and the screen on it) so i unplugged the old screen, disconnected everything, changed the battery, and put everything back where it is supposed to be. and the iphone was (almost) working like a champ (i mean, everything that i changed was working, anyway).
so, the day after i check the iPhone, and i see "No Signal" (Reseau Indisp. in french, i dont exactly know what it is in english) so i'm like [maybe i did'nt plug a cable or something] so i remove the screen and check every connectors, all were ok so i put back the screen.
and when i pressed home, the only thing i got is a white screen, i tried to disconnect/reconnect this screen, tried with another screen from another 3GS i had(and i'm 100% sure this screen is working)
but i still get the White screen of death.
i tried restoring with iTunes: while the process the screen stayed black and when the iPhone restarted (after the restore) again, a white screen, but the iphone did restore.
i tried to remove the board (to disconnect the battery): did'nt work, i got a WSOD when i started the iPhone
right now the only solution that comes in my head is to let the battery drain completly, then try to plug it on iTunes.
i know the phone still works because i was able to hear the unlock sound(before i restored) but i cannot turn it off because i have a non-working power/sleep button.
i really dont know what to do now, please help me !
(sorry if my english is bad, i'm french)
