iPhone 4S: Broken resistors after power chip replacement

Thu, 16 Apr 2015 13:32:53 -0700

Hi, I made a big mistake. My iPhone 4s wont charge. The problem is the power ic. So I decided to replace it with my hot air station. It was not easy so I destroyed the faulty chip and some resistors. They broke off.

I solderd the the new power chip successfully but I can't solder the resistors with my hot air station because the wont hold and blow off, even on the lowest air level.

Here is a picture from the problem

So how can I fix the broken resistors?

iPhone 4S: How can I fix my iPhone's touch screen ribbon/cable?

Mon, 23 Mar 2015 15:51:40 -0700

Hello, so recently I had dropped my IPhone 4s, and the whole screen was cracked with random colors of flickering. I bought a new LCD screen and stuff and took the phone apart and replaced the screen. Everything was going great until I found out that the touch screen was unresponsive. I figured the ribbon cable for touch had been ripped (I thought I saw a ripped cable), so I researched a bit. I read that using mylar tape to bind it together would possibly fix the problem, however I would like to know if black electrical tape would work the same? As far as I know they have the same abilities...?

iPhone 4S: Modify li-ion charger to charge iPhone battery?

Fri, 20 Mar 2015 18:32:31 -0700

Disclaimer: this question might show a complete lack of understanding of the finesse of electronics.

My iPhone 4S' charging circuit is not working properly, so I am looking at convenient ways of charging the battery outside of the phone.

I've found a circuit diagram posted here by oldturkey03, and I will give that a shot.

Then I had another thought; I do have old li-ion chargers, for digital cameras and such. If one of these has the correct voltage (3.7V) and the correct current rating (<=1000mA), would it be up for the task, or could this still break my battery?

I've been using this setup many times now and it's working great:

I have very simply connected the + and - terminals of the charger to the corresponding pins of the battery. Most of the jumper cables are used to keep the battery in place.

By a strike of luck, the small jumper wires fit very well into the battery plug.

iPhone 4S: Can't restore/update after doing display and battery replacement.

Sun, 15 Mar 2015 18:09:47 -0700

I phone 4s, not jail broken. Replaced display and battery and phone will still not turn on. If I plug it in the phone goes into recovery mode and shows the cord and iTunes logo on the screen but will not come on when disconnected. I can use the power button to rest the phone while it is connected but all it shows is the iTunes logo and cord icon. I have powered the phone off and tried DFU mode so I'm assuming that its not u3 since I can use both buttons. I am using the stock apple USB cable that is new. All drivers are up to date on my PC and I've tried on multiple PCs. Latest version of iTunes. I've gotten back error codes 21, 1671, 2009,-37, and maybe one or two others I can not remember.

This is a family members iPhone but I have repaired plenty of androids with no problems, family members wants all the data off of the iPhone.

I need to charge my battery externally. My only concern is overcharging and ruining the battery. I know there is a circuit somewhere that prevents overcharging. Is that circuit built into the battery, or is it part of the phones hardware?

iPhone 4S: Logic Board component fell off during screen repair

Wed, 22 Oct 2014 06:40:56 -0700

During a screen repair I had a very small component fall off right below the rightmost screw of the dock connector. It is square and appears to have 4 solder pads on it. I'm not 100% sure this is actually the correct component as I just ended up with the tiny part on my sheet after I was all done so I had to go back in and look on the logic board for missing parts.

I was wondering A) what this is as I can't even read the part number it's so small, B) is it important, and C) how can I possibly reconnect it? Thanks for your help!
