Is mosfet supposed to have +5V on top? I just used my multimeter and verified voltage literally on top of mosfet located by power chip and there is +5 right on top of it, is that normal for such a component to be "live" on the outside?

Not turning on, not recognized by pc, tried board on other phone and no good.
Try jump both in place of them maybe they short and phone not power on.

maybe a hardware problem?!?!?!?
Please give me a solution !
thank you!
I hardly think this is a hardware problem as error 9 indicates ASR and kernel issues. Try rebooting your machine or else try to restore on a new machine which hasn't got iTunes installed yet so you will start fresh

What do you mean what you have to do to the phone...
Put the sim ejecter in the hole of the sim tray put in your sim, close the sim tray and push power on

Question Freezes iPhone 4 cam after focusing

Dears,
I have an iphone 4 (model A1332), it had water damage.
So I went to our "service centre" where masters said that they replaced touchscreen, battery, wi-fi & bluetooth and power controler and returned me my iphone for testing.
In test I found that facetime camera not working(rear cam worked perfectly), so I went to centre again. Masters said that contacts of cam had oxidation (corrosion) and they replaced facetime cam.
Now facetime cam works great, but when I try to change front cam to rear cam, rear cam automatically focuses the image and freezes. After restarting camera application, screen view a closed curtains. But I can change cam again from rear to front after several attempts.
I went to masters again and they have replaced A4 processor by another processor from iPhone which works perfectly, but it also did`t help.
I kindly ask you help for solve this problem if someone have had the same problem.
Thank you and sorry for my English.

Ok what firmware are you trying to restore?
And at what percentage roughly is giving the error? (You can tell me how much of the progress bar is filled on the phone during the restore before it gives error 9)

Have you got older shsh like 3.1.3?
