  1. Samsung Galaxy S9 Motherboard Replacement, Rear Glass Removal: Schritt 1, Bild 1 von 1
    • Before you begin, switch off your phone.

    • Apply a heated iOpener to a long edge of the phone to loosen the adhesive beneath the rear glass. Apply the iOpener for at least two minutes.

    • You might need to reheat and reapply the iOpener several times during the removal procedure to get the adhesive warm enough to cut. Follow the iOpener instructions to avoid overheating.

    • The adhesive of the Samsung Galaxy S9 is very strong. A hair dryer, heat gun, or hot plate may also be used if you aren't able to open the device with the iOpener. Be careful not to overheat the phone—the AMOLED display and internal battery are both susceptible to heat damage.

    Nightmare. Impossible to get the back off so far. Being trying using the iOpener with hair dryer for last 1hr. No chance.

    You’re right Chris. I’ve tried on 3 separate occasions now and haven’t been able to budge that back. All that has happened is the pick has taken a piece out of the glass back leaving a rough edge now.

    it was not easy but doable.

    Clinton Stark - Antwort

    It’s difficult, but the trick I did to get it was to wrap the hot iOpener around a bottom corner, apply the suction cup, then I covered the opener and phone with a paper plate, better insulating the area. Then I set my blow dryer to high heat and low velocity and heated the area under the plate for about a minute. Right after turning off the blower, I took off the plate and pulled the suction cup with a cutter at hand. You’ll hear a bit of a cracking/popping noise when the adhesive is starting to give, just apply a little more force and push the cutter at the seam. This method worked great for me, so good luck and just keep at it — you’ve got this!

    Nicholas Weger - Antwort

    I used nearly boiling water in a storage zip bag on the phone for 10 minutes. I can’t really recommend this method, but thankfully the bag did not leak - an iOpener is probably a much better way to go. Regardless, the bag covered the entire back of the phone, and the phone was too hot to hold, but I still could not get the glass to budge with the suction cup after struggling with it for about an hour and multiple reheats. I ended up epoxying a 2”x2” square of PVC board to the bottom of the cover and built a relatively complex fixture that pulled on the PVC with the turn of a screw while it held down the frame by the edges. After heating the edges up again It did lift the glass enough to get a pick underneath it, but it cracked the glass and it was a pain to slide a pick around the edge while the glass was cracking all the way around. Once I finally got all the glass off, I spent the next 30 minutes (which is what this entire process is supposed to take… what a joke!) cleaning the adhesive off the phone.

    Heavy Duty Heat Gun from popular discount tool store for the win!

    Well, it is not obvious how to do this. I have no iOpener, but a heat cushion for remedy hurting muscles and sometimes a backpain. It is filled with grain of some kind and it is to be heated in a microwave oven for about 3 minutes. After that I enveloped this cushion round the phone and brewed myself a cup of tea. After ten miutes the phone was warm (almost hot) and I was able to press the tip of a small (very small) knife above the charging port into the connection between the phone body and the backplate. A very small opening emerged slowly (this is the critical point in this process) and I was able to start using the iFixit opening picks. It became obvious to me that the opening picks are too blunt to achive this with them. But after starting carefully with the (very small and very sharp) knife, everything went straight forward. Thou I had to give the phone a second heatpush with my heat cushion before the backplate came loose.

    I used my 3D printer heat bed and heated it to 90 Celcius to succeed.

    gahute - Antwort

    It took about 3 minutes on my 90 C printbed to get the first pick in. If the suction cup gives up before the adhesive does, try using some Isopropyl alcohol to clean the back of the phone, and it should stick better. Also, don't apply heat to the screen, just in case that wasn't clear.

    Used a corn bag (usually used for sore muscles) and incased the phone. It was hot to the touch, but it did the trick. Also needed a knife to have a small enough edge to start prying the back off and get the adhesive to finally pop.

    Laurie Hallberg - Antwort

    Don't Forget Step 0! Turn the phone Off and remove the SIM card tray. just to be safe, I'd recommend making a full backup of your phone onto a micro SD card in case the worst should happen. also, make sure anyone who needs to contact you knows you aren't currently available at your phone number.

    Evan Newman - Antwort

    We went for a hairdryer. Put it on hot, low blow and put the head right up to the corner. Took maybe 5 minutes per corner!

    Robert Tomohamat - Antwort

    Removing the back wasn't too difficult on my phone: several rounds of heating with the iOpener, applying gentle pressure with the suction cup, and eventually a corner lifted up without much force and I could easily slide a pick in. From there it was very straightforward and I had no trouble sliding the picks around and removing the back. The battery removal was much harder in comparison (especially as the iOpener burst when reheating in the microwave for the battery, despite following the time instructions).

    • In the following steps, you'll be cutting through the adhesive securing the back cover.

    • The adhesive in the inside of the back cover is laid out as seen in the image.

    • You'll be slicing through the adhesive in the areas shown:

    • Thick portions of adhesive

    • Thin areas of adhesive

    • Avoid prying or slicing in this area, to protect the fingerprint sensor flex cable.

    I ran into a chunk of adhesive that was in the red zone right next to where the connector was. Be careful, cut slow, I managed to make it through my working my way through things that felt like foam.

    • If the phone's rear glass is cracked, the suction cup may not stick. Try lifting it with strong tape, or superglue the suction cup in place and allow it to cure so you can proceed.

    • Press a suction cup onto the back cover.

    • Lift the back cover's bottom edge with your suction cup, opening a slight gap between the back cover and the frame.

    • This may require a significant amount of force, but you only need to open a very slight gap with the suction cup to insert your tool. If you have trouble, apply more heat to further soften the adhesive, and try again. The adhesive cools very fast, so you may need to heat it repeatedly.

    • Insert an opening pick in the gap you created and slide it to the bottom right corner.

    • Insert a second opening pick and slide it to the bottom left corner.

    • Insert a third opening pick to prevent the adhesive from resealing during the rest of the removal procedure.

    The manufacturer obviously doesn't want owners to replace the battery, or they would have a simple method like they did in the past !!! They would rather have you throw it away and replace the phone !!!!

    Well. I guess so!

    I was so looking forward to doing this.

    What a shame this type of manufacturing occurs!

    • While inserting only the tip of the opening pick, slide it from the bottom left corner along the side to the top.

    • Slide the pick around the top corner and leave it there to prevent the adhesive from resealing.

    • Slide the opening pick from the bottom right corner along the side to the top.

    • Apply more heat if the adhesive becomes hard to cut. During the removal process, the back cover is under tension all the time and is likely to break if the adhesive isn't softened enough.

    • Slide the opening pick around the corner and cut the remaining adhesive at the top of the phone.

    • Don't open the phone all the way yet. The fragile fingerprint sensor cable still connects the back cover to the motherboard.

    • Carefully lift the side of the rear glass where the volume button is located.

    • Use the edge of a spudger to pry up and disconnect the fingerprint sensor flex cable.

    • Remove the rear glass.

    • When reassembling follow this guide to replace the adhesive and reinstall the rear glass.

    • In case you want to replace your rear glass follow this guide to transfer the rear camera bezel including the fingerprint.

    • Remove fifteen 4mm screws with a #000 Phillips screwdriver.

  9. Samsung Galaxy S9 Motherboard Replacement: Schritt 9, Bild 1 von 1
    • Remove the NFC coil assembly.

    This is not quite as easy as the simple statement “Remove the NFC coil assembly” would lead you to believe. The top and left side of the plastic bracket attached to the coil have tabs inserted into the frame of the phone and you can’t just pick the coil assembly up. It takes a bit of force, and I used a spudger to gently pry along the top from right to left to pop the tabs free, and then the tabs on the left came out more easily. Do not just pull on the coil and bend it up.

    Yeah, for more detailed instructions, check the battery replacement guide and refer to steps 9 through 11.

    • Remove the motherboard bracket.

    My phone did not have a separate bracket covering the motherboard.

    jason boesiger - Antwort

    The NFC/wireless charging coil is adhered to the motherboard bracket, and in my case they both came off together.

    drbenton815 - Antwort

    Also, for safety, the battery connecter should be disconnected in this step rather than waiting until after removing the speaker cover/antenna assembly.

    drbenton815 - Antwort

    yeah, the coil assembly may take this off for you. pay attention!

    • Take out the SIM card by using a SIM card remover or unbent paper clip to depress the release lever.

    this is one more screw on the motherboard that you must remove before prying it out! it hold the board to the midframe. it is located just near the curve of the battery ribbon cable.

    • Remove the motherboard by prying it out with the spudger.

    There is another connector on the back side of the motherboard at the very bottom left that you must pry apart with a spudger before removing the mother board.
