iPhone 4S restore error 1 - GSM-Forum

balzakhaar123 · 02-05-2015, 22:54

Hello I have a water damaged iPhone, wich after I cleaned it fired up again.

But when I'm restoring it via iTunes I get error 1.

I noticed that the U18_RF was missing, and also U5_RF was gone and the signal antenna near the battery connector.

I took U5_RF and U18_RF from another board but it is still giving me error 1

I also tried to jumper U18_RF pin 2 and 4 but still error 1 :/

C126_RF is just giving normal voltage.

Is it U5_RF that's giving me the error or is there something esle?

It is baseband. Reball or check basebands power supply for short circuits. 100% solution. Reball it.

U4_RF?

Still error 1 after reballing u5

What else could possibly cause this?

Yes I already took a new u18_RF from another board and didn't work :/

Even jumping pin 2 & 4 did not work so I don't think it's a u18_RF problem.

Can U5_RF actually cause this issue?

And the phone is not powering on anymore now after changing Angelina U5?

but it is still giving normal voltage on battery connector and all the capacitors?

What else can cause the phone not powering on? Or what can I check?

I replaced it 2 times now, and even took another IC from another board. Nothing

It is giving me normal vaoltage.

I did notice capacitor C118 missing, can that cause it?

Anyone can help me with it?

Can a missing C118 cause the iPhone to not turn on?
