Samsung Galaxy Tab 3 8.0 Motherboard

Step 1

Start out by separating the screen from the back cover using the larger plastic opening tool to pry them apart.
Be careful when removing the screen as negligence can cause damage.

Separating the back cover was the hardest part of the procedure for me (a retired electrical/software engineer). I used a large flat screwdriver blade instead of the hard plastic tool shown. Go slow all the way around the tablet and expect pops as the pieces separate. I was not able to re-connect the back cover completely, accepting a paper-thin gap about 30% around the cover, but it is secure.

Step 2

Once every part of the screen is separated from the back cover, you should be able to fully remove it with your hands.

Yikes. I began carefully prizing off the screen - but when it finally came away the connector (near the top of the screen, about 1” from the right side) got ripped, so the unit is damaged beyond repair. I think it would have been helpful if your guide had warned us about this possibility and given some advice about how to make sure it doesn’t happen. I now have a broken tablet and a brand new battery, likewise of no use to me. Pretty heartbroken - the unit had been working fine, mainstay of daily use.

For any future people repairing their tablets. DO NOT REMOVE THE SCREEN. I thought my tablet was a Tab 2, but no it was a Tab 3. No heat guns needed. I ended up cracking my screen a bit. I don’t know the extent of the damage yet, but Im probably going to get a replacement screen. You need to pop out the whole thing. Not just the front screen. The reason being that there’s a sort of metal scaffolding holding the screen and the back together. This needs to be separated to put in the new charging port.

Step 3

To remove the battery you must use something small, such as tweezers, to disconnect the battery from its port.
Note: the connection lifts up to remove.

Step 4

After the battery is disconnected, use the pulling tab to safely remove the battery.

You don't have to, just be careful with battery connector.

You have to be very careful with the battery connector. On mine, the plug was difficult to remove from the base and I ended up breaking the connections between the base and the circuit board. Maybe use the pry tool to hold the base down while easing out the plug.

I just did the same thing Hugh...does that mean my tablet is trashed? Can it be repaired?

There’s also a pull tab on with label printed on the batery to make the pulling easier.

Step 5

Disconnect the relays attached to the motherboard.

Step 6

Unscrew the 2.9mm screws from the speakers using a Phillips head #000 screwdriver, then lift the speakers from the device.

Step 7

Using the plastic remover tool carefully unseat the four rectangular electric leads from the board. Each rectangle is a different size, the first one is large, the second one is medium, and the last two are small.
Using the plastic remover tool carefully unseat the square electric lead (marked in orange) from the board.
Using the plastic remover tool carefully unseat the small square and the two rectangular electric leads (marked in yellow) from the board.
