I have this same problem sometimes starts but is locked.
I discovered that a lot Max8997 heats and crashes, screen off etc ...
I'm thinking about changing it but my fear is if you can have more bad components that also heated ..
I think it's by Max8997 this is heated to 45c-50c º º but in a while the temperature is lowered but the phone and screen already off ..
Only I have to change the Max8997?

For "professionals" only recommend a replacement!
For those who have not done it before does not really stand her .....

I understand it's complicated but I like challenges ..

anyway I'll see if I return the phone to the seller ..

FLIPOXP · 08-23-2013, 19:03

I will be complicated in order to return the phone now locks me more ..
make noise and be heard but the screen freezes this is what I have to do?

Be removed without probelmas the ic but my problem is when I move the welding component and I can not ..
I only practiced with it at the moment old phone but not to remove solder.
When I remove the IC I have to remove all the tin on both sides? I have to put one flux? or tin in pasta?
I see that in the youtube video that uses a white paste is flux paste?
