How do I take apart the logic board

have taken iphone apart, cleaned everything, reassembled but we're still stuck on apple screen and only when plugged in to mains. This is a phone with no history so I'm assuming water damage.

How do I seperate the 2 halves of the motherboard/logic board to look at the insides see whats what?

Answered! View the answer I have this problem too

Is this a good question?

ok... maybe i described this wrong. I want a guide for taking off the metal cover on the motherboard so that i can see if there's any damage that's been hidden from my basic clean/dunk in iso. have been searching back over answers because i'm sure markus has put in a good diagram of what part is for which function...any chance of putting link in again?

thanks for the clarification - i edited something into my answer

you can't do that!!

measure the voltage of the battery!

and of course - chen the nand flash - i received a fluid damaged 3g with "burned" nand connections (the 8gb has 2x 4gb modules - they are soldered together and 12 of those solderings are gone)

EDIT

well, you almost gave me a heart attack. the metal covers can be removed, you can pry them carefully from the metal frame - but be really careful with that.

i'm pretty sure the battery isn't the problem...have put motherboard in working iphone,screen will only come on when on mains dock/charger. can't seem to get anything else out of it!

thought the problem was connector 4 as phone shuts down when not on charge, isn't recognised by itunes.

Why can't i take the halves apart? is this an impossible phone destroying thing to do? or is it just difficult?

no i wasn't able to solve it....am still waiting on a guru to help out. i think it's somthing to do with the power relay as i can't get it into dfu or switch off. it's not a battery problem in my case. have you tried another working iphone with your motherboard? then you'll know if it's the motherboard that's the problem or some other part of your phone. best of luck

No, sorry to say I haven't. Haven't got any 3G phone's around, only 3Gs.

I cleaned my mobo completely, even under the iron plates, but to no avail. Sadly. Thinking of sending mine in to one of those no cure, no pay repair shops. Let them sort it out.

keep me posted.
