Step 1
Remove the battery cover from your Razr by pushing the cover latch down and pulling off the battery cover. Remove the battery and unscrew the two screws holding the motherboard housing to the phone.
Step 2
Slide the edge of a credit card under the housing from the screw holes all the way around the edge of the housing until it pops off. Lift the housing up carefully so you don't damage the motherboard, which is still connected to the keypad. Pay attention to how it's oriented in the housing.
Step 3
Use tweezers to pull the connector to the motherboard off the housing. Use one of the screwdrivers to pry the tab holding the antenna and speaker cover. Leave the screwdriver under the tab and slide another one underneath the antenna, and pop it off. Be gentle. It comes up without breaking any of the tabs. Lift up the motherboard, pull it out and pay attention to how it was sitting in the old housing.
Step 4
Pull the speaker and speaker holder off with the tweezers. It might stick. Pull consistently without yanking. Replace the speaker holder and then the speaker in the new housing in the same position where it was in the old one. Place the motherboard in the new housing and place the antenna on top of it.
Step 5
Unscrew the housing around the mouthpiece. Slide it off, flip the phone over and pull off the mouthpiece. Flip the phone back over so the back of the keyboard is facing up.
Step 6
Pry up the tabs with a screwdriver, push them down through the slots and gently pull off the keyboard. Leave the key mat there, slide the new keyboard into place on top of it and fold the tabs down on the back. Slide the new mouthpiece in and the new housing around it. Replace the four screws you removed.
Step 7
Clip the motherboard connector back onto the motherboard and clip it back into place. Screw in the two screws you removed from under the battery earlier. Pop the new rubber stopper into the hole in the new casing.
Change the Housing on the Top of the Phone
Step 1
Pop out the rubber stoppers around the faceplate with a pin. Unscrew the screws underneath, and use a credit card to slide around the edge of the faceplate until it pops off.
Step 2
Remove the screw just to the side of the hinge cover and slide the hinge cover out with tweezers. On the other side, push the hinge cover out with a screwdriver. Slide the new hinge covers in and replace the tiny screw.
Step 3
Switch the buttons on the side of the faceplate with the new ones. Place the new Razr housing on, and gently pop it into place. Screw the four screws back in and put the rubber stoppers back in over the screws. Put the battery back in, and the new battery cover on the phone.
