    • Insert a SIM card eject tool or a paperclip into the small hole in the SIM card tray, located on the upper left hand side of the phone.

    • Press to eject the tray.

    • This may require a significant amount of force.

    I just successfully completed the battery replacement on m8 using this guide…thought I would add a comment at each step to follow my story. This step of course should be easy if you’ve put the phone back together.

    My HTC m8 doesn’t have a SIM card, and it might not have a micro SD card, since i can’t back anything up on it. Does not having the SIM card or the micro SD card matter in disassembly and reassembly?

    • Remove the SIM card tray assembly from the HTC One M8.

    • When reinserting the SIM card, ensure that it is in the proper orientation relative to the tray.

    • Use an iOpener or heat gun to loosen the adhesive on the upper and lower speaker grilles.

    • Refer to the iOpener guide for info on how to use the iOpener.

    I used a heat gun settings 200 at 75, but I also found using a hair dryer works just as well. Heated up the bezels came right off and for putting back on I heated it back up and they have stayed put.

    I used a hair dryer for this which worked fine but I didn't need to heat it for as long as I did. 10-20 seconds is enough to start. I didn't realise how hot it would get so after heating for 90 seconds on high heat the phone was absolutely roasting and I've got two spots of heat damage on my screen. Still all works though luckily.

    Disassembly: I did NOT use any heating elements. I have a straight edge razor (like you use to scrape off window decals). Gently push in 1 point of the straight edge and work in the rest of it. Then use a spudger slowly to remove the grills.

    Assembly: Enough adhesive should be left to reinstall the grill with no problem. Be careful align it perfectly then don’t be afraid to give a good push into place.

    What are the speaker grilles?

    • Use a plastic opening tool to gently peel up the lower speaker grille.

    • The adhesive is messy, and can be removed using Goo-gone.

    You need to get between the thin black rim and the grey speaker cover, not between the metal and the black rim.

    • Use a plastic opening tool to gently peel up the upper speaker grille.

    Be careful on these steps to not bend the grill while removing.

    What is the strip of tape for under the grill? Mine has snapped off completely

    • Remove the two silver 3 mm Phillips #00 screws from the top.

    • Remove the four black 4 mm T5 Torx screws from the bottom.

    The markers on step 8 were wrong. The 4 black TX screws are actually all in the bottom, while the silver screws are on top.

    Nice good good

    Do yourself a favor and get a proper set of small screwdrivers including smaller Torx bits T5-T10 (especially with magnetism)…you’ll thank me later. Getting the cheap kits from Amazon or included in the order will likely not work or strip easy.

    Disassembly: be easy with the screws and don’t strip them. organize your workspace. i put the top screws next to my top speaker grill on the left of my workspace (and worked left to right…so that assembly was right to left) and bottom torx next to my bottom speaker grill.

    Assembly: be easy with the screws and don’t strip them. you will definitely feel the stopping point and don’t add extra torque.

    Ashley Keith (sc0rch3d) -

    My 2 silver Phillips screws at the top are PH #000, not #00.

    At the top be careful about moving the camera lens cover.

    At the top and bottom, be careful about peeling or lifting off the speaker covers.

    • Work your way around the perimeter of the phone with a spudger and plastic opening picks to free the clips that secure the rear case to the display assembly.

    • A metal spudger is pictured, but it is best to use a nylon spudger to prevent marring the device.

    • Be careful not to lose the power button: it sits loosely in the top of the lower chassis.

    • Significant force may be required to pry the casing apart.

    Note: the pictures make it look like it's the glass the comes loose from the body. In fact, it's the metal shell the comes off, while all of the electronics are attached to the face. To get it started, you have to dig your spudger in between the metal shell and the little plastic rim that goes around the glass. I found it easiest to start in the middle, below the volume buttons.

    I wish this was more clear in the picture. I ended up cracking my screen/digitiser trying to pry the glass open... the more you know!

    I tried starting by the volume buttons but was having no luck. I found starting just under the sim card worked best. Raising the whole side and the top up allowed the rest to come out. Be mindful of the charging port at the bottom and don't force the bottom out first but rather lift the top end out then the charger will clear. Same goes for putting back together. Charger port in first them push down on the sides and top.

    Jason Cobb -

    I used guitar picks to wedge inside the case as I prised it open

    Ian -

    Why do they design it to make it so difficult to replace the battery?

    Rich Hanes -

    Disassembly: did not use any heating elements. used my straight edge razor near the top left side opposite the volume rocker (it should go in pretty far and worked until i heard the first clip pop. worked around the top and down the right side. as others mentioned, you’re getting the top loose then rocking out the unit to not screw up the charge port. DO NOT LOSE THE POWER BUTTON.

    Assembly: hold the shell with charge port up and place the power button (this keeps it from falling out while assembling). put charge port in first then slowly work your way around the side little by little. I started hearing the clips pop into place maybe as I working around the perimeter on the 3rd try. after that, give it some good force as the unit should almost be flush with the shell.

    Ashley Keith (sc0rch3d) -

    After destroying the tip of three nylon spudgers, I would like to advocate using a METAL spudger, as shown in the picture. Just be careful to minimize scarring of the metal cover. But, the nylon spudger definitely is not strong enough to release the chassis, especially since these phones tend to be pretty old and set in their ways at this point in time. With a metal spudger, I was able to separate the back from the chassis in just a few minutes, after spending over 30 minutes failing with the nylon spudgers.

    Not sure g enough for any of this work. Mine are nubs now. And left residue around the edges that I was trying to pry loose.

    Please tell me, how to put in the Power Button. It’s not symetrical.

    I would appreciate a picture of it in it’s housing or a discription.

    Th.Laahcs -

    I found that on my HTC M8 the power button needs to be a shade to the left. You can figure it out on your model by looking for the button by using a Sim Card eject tool and pressing on the power button which on my model was covered by black tape. You’ll feel the button click/press once you find it - you can then determine if the button is a shade to the left or right when you line it up with the housing with no power button. Place the phone temporarily into the shell and you’ll be able to determine the button placement, this is how I did it.

    Hector Vera -

    I too also used a metal spudger on the left side opposite the volume rocker, that seems like a good spot to start.

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