    I have 2 note 2 phones model #: SGH-I317M. I have a broken screen that does not display in my note 2 but my brother's note 2 is working perfectly. Can I either transfer the motherboard in MY note 2 to my brothers note 2 or swap the broken screen with the new screen in my brother's note 2 ? Thanks. Reach me at

    • Insert your plastic opening tool between the midframe and front panel assembly on the side of the phone.

    • Slide the plastic opening tool down the seam.

    I didn't have an opening tool, so I used a stiff guitar pick. Worked like a charm.

    for best result without any scratches or breaking frame, open the frame on table (solid), don't open on hand.

    • Continue to run the plastic opening tool down the seam.

    • Carefully pry around the corner with a plastic opening tool.

    The screen cracked using that plastic tool.

    • Pry along the top of the phone with a plastic opening tool.

    • Free the clips along the power button side of the phone.

    • Lastly, free the two clips along the top and bottom edge of battery compartment.

    Start with the top clip. You can see it located next to the three battery connectors. Insert the spludge from the side gently to push, the clip should go off.

    Once this clip is off, the bottom battery clip can be unclipped simply by gently moving the two pieces apart.

    If you're primarily following the pictures, as I was, you might be frustrated that your display assembly isn't popping off. Unfortunately, a vital step was listed in the instructions but not photographed:

    "Lastly, there are two clips along the top and bottom edge of battery compartment that also hold the display assembly in place."

    • Lift the display assembly out of the midframe.

    unblock the edge at the middle-up of the battery compart!

    • Use a spudger to disconnect the vibrator/power button assembly cable connector.

    • Disconnect the antenna cable connector.

    • Disconnect the display cable connector.

    Dear Sirs,

    My Galaxy Note II is completely dead due to lightning in the house. I guess there is a fuse or a protection somewhere but I can not find it. Can you help ? Thanks in advance, Jose

    Jose - Reply

    One idea would be to track backwards, i.e. check to see if current is reaching from the charge port to the mainboard. Looking at the following picture it seems like the fuse is - as expected - located right by the USB port. If you're lucky it could be as easy as replacing the charging board, a $10 component.

    • Gently remove the motherboard.

    • Hold the motherboard by its edges to prevent ESD damage. Be careful not to snag it on any cables as you extract it from the display assembly.

Hello Fellas,

My Note 2 has a busted wifi, bluetooth, and gps (it attempts to turn on the wifi but never actually does). I suspect it is a hardware issue since I have factory reset my phone (didn't fix the problem) and even updated the drivers on my phone. It seem to be a common problem with this phone. The only solution I have found online is to wack the back of my phone until the signal is fixed. This is a good temporary fix but the problem returns after a day or two (sometimes within hours). I was hoping I could maybe replace the wireless signal piece of hardware and finally fix my phone. Could someone point out the correct hardware piece, please. (btw: I do receive regular phone calls , text , and 4g data)

Thank you, Kevin

Great job Sam!

Just one question: What are the steps after Step 21?

It seems to end suddenly...

Secondly, where can I but a Note 2 motherboard?

Fuz - Reply

Hey Fuz!

The guide ends at step 21, because the camera is the last thing to come off of the old motherboard, it will then be the first thing to go back on the replacement motherboard. All you have to do is follow the steps in reverse to reassemble the device. Unfortunately we don't sell the Note II motherboard right now, but a quick search on eBay brings up quite a few options!

there seem to be several model numbers . I am guessing each provider has their own model number.

My Question is can I use a new board for sprint on my at&t phone and if so will I have just unlock the new board to use with any sim card ????

many thanks

rotagen - Reply

my Note 2 has died and I was told that I would need a new board. could I use a board for a different provider and just unlock the new board ??

it seems that each provider has their own unique model number. are they basically all the same just registered to each provider ? I really want to get my note 2 back up and running it is a great phone and will back up my new note 5

rotagen - Reply

Just to add in, I completed this guide with a N7105 and the antenna placement is slightly different. I only had to remove one antenna, one along the thin part of the motherboard. And when removing the front from the backplate, there are 2 clips near the battery compartment that latches itself onto the front, use the spudger to remove these 2 parts. This is very important. It's my first time opening this phone so this caught me offguard. Other than that, this guide is fairly decent considering the amount of note 2 variants available.

That’s right the same as with my Note 2, I Couldn’t get the cover off because of the 2 extra clips. And only one antenna cable

Don't you lose the IMEA number by simply replacing the motherboard? I'd like to fix my broken acceleromter and even upgrade to 32GB, but doesn't seem worth it if I have to hack the IMEA just to move it from the broken mob.

Doesn't replacing the motherboard cause the IMEI to be lost?

yes you can change the motherboard of n7105 to n7100 but have to do some alterations to the middle body frame so thatthe motherboard sits in the frame perfectly
