Introduction

A damaged/broken or even corrupted motherboard can render an entire device useless. This guide highlights how to remove the back cover of the tablet in order to get to the motherboard as a means to replace it.

    • Make sure the device is turned off before attempting to disassemble it.

    • At the top portion of the memory card slot, use the small metal spudger to create separation between the back cover and the rest of the device.

    • The small metal spudger is only used to create separation between the back cover and the rest of the device, not to remove the back cover.

    • Use the intermediate metal spudger in place of the small metal spudger to remove the back cover. This is done by sliding the intermediate metal spudger around the perimeter of the device, beginning at the top portion of the memory card slot.

    • The second picture shows the internal portion of the device once the back cover is removed.

    • Use the bent precision tweezers to disconnect the battery connector from the motherboard.

    • Avoid touching the motherboard with the tweezers. Metal tools such as the tweezers can scratch the motherboard and potentially cause damage.

    • Use the spudger to flip up the ZIF connector to unlock the rear facing camera's flexible cable.

    • Then use tweezers to gently remove the rear facing camera from the device.

    • Use the spudger to flip up the ZIF connector to unlock the front facing camera's flexible cable.

    • Then use tweezers to gently remove the front facing camera from the device.

    • Using the flat end of a spudger, carefully wedge the motherboard from the case.

    • Be patient, using gentle and even force, while wedging the motherboard out of the midframe with the spudger. Excessive flexing of the board may cause damage to components or circuit traces.

    • Using your fingers, gently remove the motherboard out of the device.

    • Once the motherboard is removed, the device should look like as illustrated in the third picture.

Conclusion

To reassemble your device, follow these instructions in reverse order.

I have a tablet that has previously had its battery replaced and well pretty much the red text in step 3 happened would that small scratch cause it to not turn on at all and require a replacement motherboard?

you would be correct that it COULD as it says, but take a magnifying glass (or a phone app that magnifies and examine the scratch, if you can see the copper on the pcb is in fact showing and cut the yeah if not perhaps that is not the problem (in trouble shooting one needs to check to see that they are correct and not just assume that is the end of the road, it could be something else (this post is very old i answer only for those getting here and wondering the same thing. answers to questions are good things, questions only are just internet clutter. someone here could have answered this by now.

Can you still revive photos and video if you change mother board

if the pictures are on the old motherboard then now. if you are replacing with a motherboard (because the display and touch are messed up) from an old machine that worked then anything on the motherboards memory that you are putting in and powering up are potentially within your reach. (if you are correct that the board you are putting in is working) (there is more than one reason to replace a motherboard; i am taking a perfectly fine board out, putting in a board that is my old machine with valued data, then once i got my data i will be replacing the brand new board right back in, (most likely) and i will have saved my data (my backup was a few months out of date and i wish to recover that)

this must be said, people do NOT use metal spudger. use plastic guitar pick or similar for this stuff, try not to use needle nose plyers, use a plastic stick on battery connection detaching at right angle to connector (not anglarly as this may undo some of the wire connections.

always examin connectors for latches or locks some connectors will have a folding door, not activating these may wreck your connector. be observant, remember you have lots of time no need for rush in this kind of stuff.

another thing not mentioned is you should destatic (or ground yourself) as your body may have enough charge in you to mess up some chips on any computer parts.
