- Hi Patrick, I see from your original post...you changed your display. So more than likely when you removed/install
ed the connectors at the top of board...you probably knocked a little chip off of it. To test chip above audio jack connector, just solder across (bridge) both connections. If your camera works, just leave it that way. It will work fine.
- The after market casings will work. You just have to shim up the Mute, Volume, & Power buttons. Black electrical tape works great.
- 1st I would just try to charge the battery thru wall outlet. Give it a couple of hours. Sometimes new batteries need to be charged.
- It might be the dock connector assembly in bottom of phone. The Home button, when pressed, makes contact with contact points on top of dock connector. Your USB cable plugs into dock connector port. Your speaker is also housed in it as well. It would probably be around $10.00 to replace.
- Heating up while charging is a common problem associated with a bad PMIC (Power Management IC) chip on logic board. I would try a new battery...just in case, before messing with board.
- I specifically buy 3gs iphones with DIM screens (no backlite) to repair. In my opinion, here are the most common causes: 1. Corrosion at #1 LCD connector on board and/or LCD 2. Bad LCD 3. 6R8 coil & chip/curcuit problem The quickest test of backlite curcuit is: Power on phone, remove screen, and do lite test at pin 3 of #1 LCD connector on board. If there is power...backlit
e curcuit is probably not broken. If not, troubleshoot backlite curcuit.
- A perfect substitute for the copper contact on logic board is...the copper contact on dock connector antenna. You should be able to use the one from your old casing. They look almost identical. Update: The correct fix for antenna issue is to replace the dock connector assembly. Simply transfer your old one to new casing. Trust me...you signal strength will return. The antenna signal comes from the flex strip that sticks to the bottom of the dock connector...whi
ch has a copper contact that makes contact with metal frame when installed. Most "After-Market" dock connector assemblies have POOR antenna flex strips. I primarily repair & sell 3gs iPhones.
- Those error codes mean phone is not in Pwned DFU mode during restore. Here is a way to make sure your iphone is...in fact...in "Pwned" DFU mode. 1. Turn the speaker up on your computer 2. When ever you put your phone in DFU mode you will hear 2 sets of beeps...one around 8 seconds & then again around 18 seconds. Pay attention to the sound. 3. Run iREB to put your phone in Pwned DFU mode...you should ONLY hear a high pitched "ding" when Pwned, NOT any beeps as well...like when putting into DFU. iREB will STILL display message that phone is in Pwned DFU mode when this happens (ding & beeps). But, your phone is kicked back into DFU mode. When this happens, close iREB, put your phone back in DFU & run iREB again. If all you hear is the "ding", you should be able to bypass those errors.
- Also, make sure the "contact bracket" that sits beneath the battery at the connector is properly installed. It makes contact when back cover is installed.
- What was wrong with the original screen? I believe the screen you bought is bad. Here is a quick check you can do: With the GOOD screen installed on the phone you were replacing screen on...reset the phone by pressing the power & home buttons together until phone reboots. Hopefully you get the apple logo again. My experience...wh
en a white screen appears, the phone has to be reset...even when you install a good screen.
