    • Insert a fingernail or plastic opening tool into the recess in the bottom right corner of the battery and lift upward.

    • Remove the battery away from the phone.

    The battery will need to be charged after it is placed in the phone. No one told me that and I bought a battery and thought it was bad. Keep the phone off and insert the charger. You will need to charge it for several hours before you can use the phone.

    • Using a fingertip, pull the microSD card straight down out of its slot.

    • Remove the microSD card from the phone.

    I found removing the SIM/SD card with my fingertip a little difficult – not enough friction. So I used a 'rubber' (in US English it's called a pencil eraser or just simply, an eraser.

    Simple, cheap (zero) and effective! :)

    • Repeat the above procedure to remove the SIM card.

    Actually this isn’t as easy as it appears in the photo and instructions, since the SIM card does not have a notch that you can use to pull it out. In my experience I’ve found that the best way to remove the SIM card is by pressing down somewhat hard on the SIM card, and then push-pulling it outward.

    • Use a plastic opening tool to pry up the plastic midframe connector panel.

    • Remove the connector panel with a pair of tweezers.

    • There should be enough adhesive to readhere the panel upon reassembly, otherwise use a small amount of double-stick tape.

    In my experience I have always removed this Home button protector panel with ONLY a plastic opening tool, and I have never found adhesive beneath it.

    • In the following steps you will be using an iOpener to warm the adhesive affixing the display assembly to the rest of the phone. This will allow for a safer, easier screen removal. For proper iOpener use, follow our iOpener heating guide, make sure to pay attention to all warnings.

    • Place a heated iOpener on the left side of the phone for at least 90 seconds.

    • Reheat the iOpener and place it on the right half of the phone.

    ¿se puede hacer con la pistola de calor?

    Diego Alomoto - Contestar

    Si, puedes utilizar la pistola de calor también, pero ten cuidado ;-)

    Sandra Hiller -

    Otra opción es usar una “placa calefactora” que, según yo, es la opción mas “profesional” ya que con ella se puede limitar la temperatura, para que no se malogre la pantalla táctil (la “digitizador” detŕas del vídrio).

    OmniWeb Technical Education -

    Another option is to use a “hot plate” which, according to me, is the more “professional” option since with it you can limit the temperature, so that the touchscreen doesn’t get ruined (the “digitizer” behind the glass).

    OmniWeb Technical Education - Contestar

    A hairdryer on low not being used statically is also an easy option. Or if your a caveman or low tech, and all you have is a single baby sock and metal bb’s or little rocks, as long as they’re not silica rocks, put them in the baby sock, at the edge of your cave campfire to warm them and thats all you need. -retired aviation engineer

    • In the following steps you will be using an opening pick to separate the adhesive securing the front panel glass. Only pry where directed. If you experience resistance, stop sliding the opening pick and reapply heat.

    • Insert the edge of an opening pick underneath the bottom right side of the front glass.

    I hope this helps others:

    my screen was STRONGLY glued to the midframe, it was impossible to remove it without breaking it, be very careful with the copper adhesive in the midframe!!!

    I can't even understand how this guide doesn't mention it properly!

    Pedro - Contestar

    Yeah, the real trick with these types of screens is to measure (or just “have a feel for”) an adequate temperature with the heat pad (e.g. iOpener), or heat gun, or hot plate. First you have to heat up the screen just enough so that you can “break into” one side without breaking the bezel or the glass, and then verrrry carefully and verrrrry gradually insert plastic opening picks (or even playing cards) as you make progress around the exterior border of the phone. Whenever I do this, I always insert 5-6 objects (again, plastic picks or playing cards) before I fully remove the digitizer-glass assembly, which typically ends up as follows as I move around the exterior border: one pick at each of the four corners and one pick on each of the two sides. WARNING: DO NOT INSERT ANY OBJECT BENEATH THE GLASS MORE THAN A FEW MILLIMETRES FROM THE EXTERIOR BORDER.

    • Slide the opening pick up along the right side of the display.

    This is not as easy as they make it seem in this guide. The real trick with these types of touchscreens is to properly measure (or just “have a feel for”) an adequate temperature with the heat pad (e.g. iOpener), or heat gun, or hot plate, that you use to heat the adhesive beneath the glass exterior of the digitizer-glass assembly. First you have to heat up the screen just enough so that you can “break into” one side without breaking the bezel or the glass, and then verrrry carefully and verrrrry gradually insert plastic opening picks (or even playing cards) as you make progress around the exterior border of the phone.

    • Carefully slide the pick around the corner, stopping before the speaker grille at the top of the phone.

    Be sure not to nick and tear the capacitive touch chip interface that meets the LCD screen here! I caught it and didn't even feel the resistance. :-(

    • The adhesive securing the top of the phone is only a narrow strip above the earpiece speaker. Slide the pick along the top of the speaker to avoid damaging internal components.

    • Slide the opening pick across the top of the phone, being very careful not to insert the pick too deeply.

    I have been extra careful, and it did not prevent me to sever the flat cable in the upper left corner. The cable is very close and you should take extreme caution.

    • Carefully slide the pick around the upper left corner.

    • If you encounter any resistance from cooling adhesive, reapply a heated iOpener to the left side of the phone.

  14. Samsung Galaxy S5 Motherboard Replacement: paso 14, imagen 1 de 2 Samsung Galaxy S5 Motherboard Replacement: paso 14, imagen 2 de 2
    • Slide the opening pick all the way to the bottom left corner of the phone, making sure it is securely placed.

    • In the following step you will be placing an iOpener over the home button end of the phone, you won't want your opening pick to slip out.

  15. Samsung Galaxy S5 Motherboard Replacement: paso 15, imagen 1 de 1
    • Place a reheated iOpener over the bottom portion of the display assembly.

    • There are delicate components in this portion of the phone, you want to ensure the adhesive is warm and easy to loosen to protect the phone.

    • The bottom end of the phone contains the soft button and home button ribbon cables. If you insert the opening pick too far into the phone you risk cutting these cables.

    • Slide the very end of the opening pick across the bottom edge of the display to separate the last of the remaining adhesive.

    How do I avoid damage? I tried this and now have to get a new screen, LED, and digitizer since the grey part under the glass snapped and cracked in many areas. I had to discard it and order a replacement to fix the phone.

    • Twist the opening pick to detach the glass from the phone.

    • If the front panel does not detach easily, it may require additional adhesive cutting.

    Be aware that there is adhesive on the inner parts of the screen. Plan on replacing this screen and digitizer as well.

    • If the front panel is not easily freed, the adhesive on the soft button cable may need to be separated.

    • These cables are thin and easily damaged, therefore be certain you are only peeling them off the display assembly and not lacerating them.

    • Insert an opening pick under the soft button icons on the display and pry the button cables down off the inside of the front panel.

    Accidentally cut one of the side buttons. It wouldn't come out, the screen was badly cracked.

    My digitizer was glued to the chasis, the glass came up separately and the digitizer broke when I tried to pry it up.

    ken - Contestar

    That’s actually probably because you might not have heated the sides of the screen (where the adhesive is located) enough before prying up on the exterior border of the glass part. It’s very difficult to know the tolerance limits of such devices if you’ve never seen them apart before, and as such one can easily get confused between where the glass ends and the digitizer begins. On my first smartphone repair I broke a digitizer, so I know how it feels.

    • Slightly lift, but do not remove, the home button end of display assembly.

    • Do not remove the front panel entirely. It is still attached by a connector.

    • If you are reusing the home button flex cable, be careful not to sever the cable from the home button. Adhesive can cause the cable to rip apart from the home button. While the home button will still work, the fingerprint scanner will not.

    The display assembly I purchased from ifixit.com included a new home button with a new flex cable. If you have the same, I'd recommend removing the home button in this step.

    pdub01 - Contestar

    Same here. My home-button flex cable extended under the main board rear cover plate, and would have required removing screws to extract. So I left the original home button installed, and removed the one that came with the new assembly.

    The ‘reverse order’ step are misleading. It is not trivial to reconnect the main screen flex cable to the main assembly — lots of trial and error to get it snugly plugged into the receiving connector. That part is glossed over. (Dissassembly is trivial. Reassembly is hard.)

    After putting the screen and connectors on, I learned that there’s some plastic edging on the BACK. I had to remove the screen since it effectively wraps the home-button key. The new screen cracked. Great.

    Peter Nicoll -

    Sansumg S5 is the stupiest design (for repair) ever.

    I have fixed s2,s3,s4, note, note 2 and note 3

    All of them, you can get into the logic board from the back without touching the screen assembly.

    With the S5, just a simple problem could cost you buying a new lcd assembly.

    You must remove the lcd in order to remove the screws for the logic board cover.

    I purchased a cracked lcd S5, so I can replace it and sell it. My mistake was I did not did a research on the tear down (thinking it should the same as previous S model.

    To make story short, lucky for me, I did a dry test of the entire phone, before glueing on the new lcd assembly.

    Because the front camera lens was damaged, cost $5.

    If I glued the lcd, it would be 50/50 chance that I would crack the new screen.

    So any repair that you need to do on the S5, you will have to consider the risk of breaking the LCD.

    I hope Samsung change the design on the S6. Which I doubt it. Because the higher cost of repair means people won't fix them = more new sells

    How can I find out if I messed my phone up . the person who glued the screen on didn't glue it on right , so I tried to take off the screen and I got it off but now that I try to put it back on the screen is black .

    cholitaesh21 -

    I know this reply is a bit late, over 2 years late, but I just wanted to add to idevice Recycle that the way "they" designed this phone is exactly as you described, to make it wayyyy more difficult to fix even the most simplest thing on this phone. Inverting the motherboard, designed exactly the opposite way of the S4 (as you described), from their standpoint of view, as you'd have to admit, was a brilliant idea on "they're" part.

    I've torn apart and fixed many cell/smart phones in my days thus far, but mostly iphones by far. A friend passed

    me one of these phones this past week. I've never messed with one before so you already know, even though I

    have much knowledge about them, this site was the first I visited about this phone. Needless to say, go figure.

    They did a really great job though making this phone one of the most difficult phones to do any type of repair

    on. Adhesive sucks. But eh, all is well with a bit of time and patience. Had to replace rear camera and middle

    bezel frame. Time to off it....

    you_mad.lil_fella -

    This guide may have been written for a different revision but the SM-G900F that I just repaired had glue sticking the entire of the rear of the screen to the chassis making it very difficult to remove. Had to use a spudger and push it down the inside of the phone separating the copper film from the chassis to free it up. Would be easy to damage the home button cable but I was ok.

    Adam - Contestar

    I had the same thing happen just now. I was working on a G900A. A real PITA!

    mcr4u2 -

    Is there a need to put adhesive after removing the screen?? If so, do you have an adhesive recommended...

    garrykufa2000 - Contestar

    Should be. i recommend using 3m strip double sided adhesive

    leiki42 -

    I had the same issue as idevice recycle. The model S5 that I was working on had a huge amount of glue on the back of the lcd which I wasn't aware of - this caused me to crack the glass which then literally broke the lcd in half (costing me £120 for a new screen!!!)

    I've repaired all manner of Samsung products over the years and I've never had any issues with any model apart from this one. My advice to anyone doing this repair is once you have managed to unstick the screen from the frame, before attempting to remove it, apply a bit of heat (but not too much, you don't want to damage anything) to the back of the phone where the battery normally sits. This is where all the glue on the back of the lcd is located which sticks the lcd to the frame of the phone - I wish I knew of this before trying to remove the screen!

    Clems - Contestar

    The guide needs to mention that the LCD is firmly glued.. Mine was bust anyway, but Step 19 is not fit for purpose.

    Dave - Contestar

    So this really blows. I needed to swap the logic board from a phone with a cracked screen to one with a good screen. Yeah that’s not happening. I now have two cracked screens… Thanks Samsung! The difficulty on this should be way higher. As others have said, the screen is glued on the underside over a large portion where the copper foil is. It’s not coming up easily or in one piece.

    Jeremy Buseman - Contestar

    If you want to make the reassembly easier, be careful to not separate the Home button assembly, from the glass. Instead, just carefully pry away the soft button adhesive connectors.

    • Use the sharp tip of a spudger to lift the front panel assembly cable connector straight up off its socket on the motherboard.

    • Safely remove the front panel assembly from phone.

    • If your replacement display did not come with a home button, follow our Home Button Assembly guide to transfer your old button over to the new display, or install a new button.

    Absolutely wonderful! Worked like a charm. This is the easiest replacement I have seen so far on an Android. :)

    Paul Frutiger - Contestar

    This was all a breeze until I removed the screen and the LCD and digitizer crumpled on me now I have to replace the whole thing not just the charge port which was the initial issue… Great guide though and thanks it helped. Minus the panic attacked when all the parts started to crack and break as I removed the glass and now digitizer or LCD stayed safe for replacement.

    cbressijr - Contestar

    Be VERY careful of the flex ribbon on the LCD …it'll break with the slightest twitch…one of mine ripped totally in half

    fady awad - Contestar

    The difficulty of changing the S5's display is enormous. Not only is it glued around the edges, it's also glued strongly to the midframe. If you ignore this, damage is inevitable. The digitizer flex cable is also very easy to kill. Glue sucks. When assembling the display, the edge bonding is not enough; you need special double-sided adhesive tape that is stuck to the midframe so that the display does not fall out again so quickly. Before doing this, you have to thoroughly remove the old adhesive on the edge. I have successfully performed this procedure once but would never do it again.

    • Remove the ten 3.4 mm Phillips #000 screws from the display side of the midframe.

    It’s probably a good idea to remove (and subsequently screw back in) these screws in a sort of “star fashion” (e.g. alternating from top-to-bottom, left-to-right) in order to equally distribute the tension.

    • Flip the phone over and remove the following screws from the battery side of the midframe:

    • Gently run a plastic opening tool down along the left inner side of the interior frame to separate the three white plastic clips.

    There are also two more white clips just along the edges of the battery connection terminals (to the right of the 3 shown in the pictures). Using a spudger to pry these loose too will make separating them later much easier.

    Peter Morris - Contestar

    Yes, I second that! You definitely need to loosen those two other clips or you may have problems separating this interior frame from the midframe.

    • The midframe is composed of two halves that encase the motherboard.

    • Gently pull the long sides of the silver bezel out away from the phone to separate the two halves of the midframe.

    • It may be helpful to gently push in from the inside of the battery compartment, but be careful not to flex the interior half of the midframe, as the motherboard is mounted to it.

    maybe my phone was stuck a little, but i had to work it pretty hard to get this step. Just take your time.

    andrew beals - Contestar

    Personally I wouldn’t recommend separating the midframe-motherboard assembly like this. What I recommend is the following: 1. Insert the flat end of a spudger between the main speaker grille and the main camera assembly (technically, between the gray and black plastic pieces. 2. Pry up on the black plastic piece (using the gray plastic piece as a fulcrum) in such a way that allows you to lift that end of the interior midframe-motherboard assembly from the inner midframe (see step 27). THEN 3. Once you have created enough space, insert a triangular pick tool, and THEN use a plastic opening tool to pry any remaining corners out of the silver bezel (see step 26). WARNING: BE VERRRRY CAREFUL WHERE YOU INSERT TOOLS or apply pressure because there are many sensitive components along that top part (where the cameras and infrared sensors are located).

    The white plastic cap which fell out is actually the piece that covers a small hole marked R2 near the original philips head screw you remove when first disconnecting the small display connector. The good news is that this cap can be put back on after fully reassembling the phone.

    • Some models have two antenna cables (blue and grey/white). Remove both of the cables.

    Please let someone know about the screw under the camera and flash/heartbeat monitor, holding the motherboard to the midframe. I do not see a step for this before trying to remove the motherboard.

I dropped my Galaxy S5, gps for maps, compass etc... works fine, but for Endomondo and Strava that requires a location is not working, before the problem it showed GPS signal Ready, Now it just keeps ideling looking for location (GPS), dissasemble to check for any loose connector or loose screw and found nothing, What can be wrong and how to fix it?

So a safe fell on my s5 after bouncing off my head,I'm ok as I have a hard head but the s5 is shattered.so I need to replace the bezel and LCD assembly , it's cheaper to buy a bad esn phone for parts.My question is if I could put my AT&T mother board in another carrier phone.as I have it unlocked and rooted the way I want it and do not want to do all that again.

Please make sure that you have re-fed the home button cable through the chassis before you place and seal the new LCD + Digitizer unit onto the phone. If you are replacing the chassis too please beware and DO NOT forget to re-screw all 10 screws that fix the chassis to the motherboard before you place and seal the new LCD + Digitizer Unit. You don't want to know what made me post these two essential things you might forget. Let's say I'm suddenly very experienced at opening this phone ;)

Justin - Contestar

I have an S5 that is totally dead. I tried all of the basic things like remove and try different battery, reboot etc.. There is no response, no charging light. Would replacing the motherboard fix it?

Hello

All of a sudden while charging the battery my perfectly working Samsung s5 G900F has turned itself off and cannot turn it on any more. The battery cannot be charged and Recovery and download mode cannot be activated either. I was thinking to replace the motherboard with a new one and move the memory chip onto the new motherboard. I was wondering what tool will I need to remove the memory chip fro the existing motherboard to place it on the new one, and whether this is something that can be done easily or it is advisable to get an expert technician do it.

Thank and regards,

Alex.
