[Captivate General] bloodhawk:
My apologies for bumping such an old thread... But i got a captivate to serve as a backup phone, and i slapped over ICS on to it..

Everything was super awesome.... BUT! not the Back button.

A few minutes of google'ing later, im here.

So after reading through this thread, and the one linked to in the OP, i opened up my Phone and ....well....went on with it.

50 Minutes later :

Some Tips :

1: Once your down to the frame with the LCD assembly stuck to it, first remove the Antenna Module. Under that disconnect the black ribbon connector. (This ribbon connects the capacitive button module to the main board).

2:

Before starting to Pry apart the LCD from the frame, take a hair dryer and heat up the edges of the LCD Assembly's frame.

This helps a freaking lot in prying it apart. Plus it somewhat preserves the 3M adhesive tape present underneath, and can easily be reused.

3: Start prying open the LCD, from the Ear piece side.

Take your time and DO NOT!! And i freaking mean, DO NOT!!!!! rush through while removing the LCD assembly.

4: When your almost half way through (or slightly more , but significantly above the capacitive buttons) take a peak between the frame and the LCD assembly, youll see the "Bridging/Connecting" ribbon i mentioned earlier and it might be stuck to the LCD's back.

->

the best way to proceed further is to simultaneously heat up the "glued" parts and slowly continue with removing the LCD. This way, the glue will not stick to the whatever parts it is meant to stick to , THAT strongly and will be much easier to remove.

5: Now as soon as you reach the part where you can see the Capacitive button module sticking to the LCD assembly, go into SUPER FREAKING SLOW mode...

THE RIBBON UNDERNEATH IS VERY VERY FRAGILE! ONE YANK AND YOU'LL HAVE TO PURCHASE A NEW CAPACITIVE MODULE.

*Best way to do this is, to again simultaneously heat the concerned parts while slowing pulling the LCD assembly and the capacitive button module apart.*

You can try going LEFT-RIGHT-LEFT-RIGHT alternatively, to slowly make the adhesive give away.

6: After you have the LCD assembly out, its pretty much dependent on how stable yours hands are at slowly etching out the Light gray parts.

-> You can hold the LCD assembly against a TABLE LAMP / some light source, to better see which parts of paint you need to etch out. *i Almost etched the whole of my back button* So be very careful and gentle as well PATIENT!

Before assembling the LCD back into the frame, i took a small piece of paper (about the size of the capacitive button module) and stuck it between the frame and the module. Just so that it makes better contact with the LCD assembly.

7: Stick the LCD back onto the frame and again heat up the edges. Also while putting the LCD back together, make sure the adhesive tape has not lumped up on any of the edges (This might have happened while trying to pry the LCD out) , if it has, then just gently even/flatten it out. Stick the LCD back and heat the edges. Rest, just take a soft cloth and squeeze the LCD's edges and frame together,so as to make sure they stick together properly. The heat really helps in bonding things here.

Assemble back the phone, blah blah.

I used a CREDIT CARD to start prying the LCD away from the frame. It was pretty easy, because of the heat.

DO THIS AT YOUR OWN RISK! I AM NOT RESPONSIBLE IF YOU SOMEHOW MANGE TO MESS UP YOUR PHONE! Specifically the LCD and the CAPACITVE TOUCH MODULE!

Big thanks to the OP for posting this.
