Is this what it's supposed to look like when i ripped the Ribbon off the LCD and circuit board?
Ok. When I yanked off the ribbon on the LCD, I got some gold things attached to the green tape like this:
I just wanted to ask if it was normal for those things to get pulled off. Here's the picture of the LCD and Circuit board after i took off the cable.
Altogether, I just wanted to ask if I'm still able to buy a ribbon cable and replace it. I don't know where the gold things came from. Hopefully, it didn't come from the phone. But if anyone had this problem, please notify me. Because I don't know if a new ribbon cable would still work. Thank you.

Resoldering is OK, but reinforcing the connector with a bonding material to prevent the connector from moving is also required.
As for the LCD ribbon cable, there is a horizontal lock down latch, about an inch long. that locked the ribbon to the board. If that latch is cracked, broken or missing, it is game over for the GPS. Yes, the latches can be replaced but it is very tedious.
If the latch is ok, all you need to do is flip the latch up. Slide the ribbon cable into the mating connector, with the gold contacts face down. Slide the ribbon in as far as it will go and using two fingers spaced at either end of the latch, flip the latch down, locking it into place. It will grab the ribbon and make the connection to the board.
Strip the unit and remove the circuit board (just a few plastic clips, no screws). Remove the LCD assembly from the circuit board (more plastic clips and an eight pin push connection). Removed the LCD unit from the clear plastic housing (more plastic clips). Finally heat up the plastic ribbon where it is stuck to the circuit board (hair dryer will do trick) and then firmly press it onto the circuit board... probably worth doing this several times; in effect you are remating the ribbon to the circuit board by softening the adhesive. Put it all back together and it should be working again.

Line faults & possible causes to LCD & Plasma screen are given with illustrations. You can get an idea about the fault to an extent. Faults to all LCD & Plasma screen are similar, irrespective of its brand and screen size.
When the LCD Controller cable is diconnected from the LCD panel, the screen should be completely white due to the Liquid crystals do not have the bias voltage to block the backlight from coming through the front of the screen. Unless you have intermittent shorts circuits on the LCD controller board (part of the LCD panel) that load down the 5vdc (logic power supply). The capacitors on all the board look OK?

No..... it is not possible to repair a cracked lcd....
Let me explain why....
The LCD panel is more than 1 layer... the sides and top/bottom have contact strips that the pixel grid connects to it is not just a piece of glass that magically shows an image.. also.. it is connected to a circuit board which wraps over the top and sits on the backside of the backlight...this Ribbon tape that connects the lcd panel to the circuit board is integrated into the Lcd panel itself... and has magnetic tape and contacts integrated into it as well... these cannot simply be ripped off or removed and switched...
Nor can you simply put a patch kit on the LCD to fix the crack.... Once it cracks, it will slowly grow in size and spread....
You can however change the front glare sheets and polarized sheets that overlay/underlay the lcd panel .. this is done to remove scratches and blemishes and such....
I just finished disassembly and it wasn't that bad. Take off all four screws around the battery, then carefully but forcefully take the plastic casing off. Then, take the 2 screws on the main circuit board. That will reveal one connection for the ribbon cable, take that off. Under that is the backplate sliding mechanism of the phone. There will be 6 screws on this assembly, one of them under cable the connects to the keyboarb (bottom right). You will have to take off a green tape and also a gold padding to get to this final screw. After that is off, you will see the other half of the ribbon. Take that one off also, just yank it off. Install the new ribbon tape, make sure you don't rip it, and you're set.
