I noticed this 8300 series was missing from the FAQ, so here it is.
First, you will need both a T-5 and T-6 driver.
Remove the battery cover, and the two T-5 screws at the top.
Next, remove the bottom piece. This may require some GENTLE prying from the hole that is located somewhat underneath it. Be very careful with this step, try and pull the piece away. The brown ribbon underneath is the antenna, and if this is damaged then you will have 0 reception.
Next, gently pull back the side pieces. Note that these are still attached at the bottom, you simply want to loosen the clips. This step may not be necessary, but I have found that it lets the front come off more easily.
Then, gently remove the front plate. There may be a seal between the front faceplate and the LCD that will want to stick to LCD. You may need to replace this seal if it doesn't come off in one piece. Once this step is done the keyboard will be lose and may just fall out, depending on how you are holding the device.
Now, remove the 2 bottom screws using a T-6 driver.
Next, remove the 2 center screws, using your T-6 driver.
This will separate the back and center pieces.
At this point you can access the LCD and all internal workings of the device. Simply reverse the directions to reassemble. I have noticed that the side pieces should go on TOP on the metal around the LCD for the best fit, even though it looks at first like they should go between the metal and the circuit board.
If removal of the lcd is necessary (for example: you got the device wet and want to alcohol wash the circuit board) the lcd display is delicate and is stuck to the circuit board pretty good. it's recommended to use a credit card between the display and the circuit board to gently pry the display off of the circuit board.
Do this in a clean environment, and it is recommended to wear gloves, as fingerprints on the screen are quite the pain to remove.
