hi bro.. I can give some starting point using iphone 5 schematic diagram and component layout diagram

C327 is your problem here's the component layout

to know where can connect c327 here's schematic diagram

to check where can jumper the C327 here's the nearest capacitor c320 and c321 but make sure u know the common ground of capacitor before you make jumper. don't make mistake it's POWER IC.. check battery connector if shorted before put battery or power supply okey? double check your diagram bro I know u can solve it

thanks for the answer but what u mean find the common ground sorry im new to this.thanks

bro here's the pic..get tester and test the two side of C327 to check which line is missing. If supply line missing just make jumper to supply line of C320 or C321 if ground line missing just jumper to ground of C320 or C 321

hi the supply line is missing so would I jumper c327 ground to supply line of c320.thanks

No, no. no!
If you do this, you'll make a short!

When you replace C327 you connect one side to ground (the intact side on the pcb) but there's the pad missing at the supply-side, correct?

So you make a jumper from the supply-side of C327 to the supply-side of either C320 or C321.

ok thanks but i don't have cap to replace, could i take off 3gs board

PappaBaer2002 · 11-06-2014, 10:04

Have you tried the function without that cap?

On 3GS logic board there is no matching cap. You can find 10µF caps there but the package size is different, you need a 402 package and on 3GS they are 603 which means they are bigger.

wshah26 · 11-06-2014, 20:04

is there any on iPhone 4 motherboard

PappaBaer2002 · 11-06-2014, 20:39

No, same as on 3GS logic board.

But what about the answer concerning the function without this cap?

wshah26 · 11-06-2014, 23:32

its connected to pmic, but is still working but not tested all functions yet

wshah26 · 11-08-2014, 02:11

would it be ok to use done without cap
