Introduction

Use this guide to replace the headphone jack/micro USB board in your HTC One M8.

Please note that your device may have a large amount of copper shielding and tape covering the back of the display assembly, as shown here. If this is the case, you'll need to gently remove it to get at the motherboard.

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.

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.

Use a plastic opening tool to gently peel up the lower speaker grille. The adhesive is messy, and can be removed using Goo-gone. The adhesive is messy, and can be removed using Goo-gone.

  • 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.

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.

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

Use a spudger to disconnect the two ZIF connectors. Use the flat end of a spudger to disconnect the black antenna cable. Use a set of tweezers to pull the two ribbon cables free of the ZIF connectors.

Note that there are two hardware versions of the replacement part. One has one antenna connector, the other has two antenna connectors. The iFixit part labeled "Sprint" is the one-connector version. It is the most common. It may be labeled "16GB" on ebay and from other sellers. My 32GB T-Mo device required the "16GB" version of the hardware, so use caution when ordering. The iFixit part labeled "Verizon" is the two-connector version. You may see this one labaled "32GB" on ebay. My understanding is that the 2-connector part is for Verizon & AT&T Windows M8s, but I could be mistaken.

If you don't know which hardware you need, and you are ordering parts before cracking open your device, I would suggest (at least at 2017 ebay prices) ordering one of each and returning the one you don't need.

Be mindful of the small ZIF connector, as when you remove it, it will stick out from the back of the phone and can be easily damaged if you put the phone with its back on the table. Better put it flat again after you loosen the cable

As happened to me; the white part came loose, but I managed to put it back. However, it doesnt have as much r'resistance' as initially. Nevertheless my phone is still working, so probably the small ZIF is only to keep the cable in place. This kept me sweating for quite some time...

Remove the single silver 4mm T5 Torx screw securing the headphone jack/micro USB board. You may need to gently bend the small ribbon cable out of the way to get to the screw. Use a pair of tweezers or a plastic opening tool to gently pry the headphone jack/micro USB board up and out of the phone.

There is a small rubber pad stuck to the inside end of the headphone jack. You can see it in the 3d picture that goes with this step, slightly offset to the right. Your new part will almost certainly not include this rubber pad. Stick it on the new headphone jack. This helps keep your M8 a little more water-resistant, as the pad is covering a small hole.

There is some adhesive sticking the board to the phone, you will need to reapply the heating pad to easily lift of the part.

There are also small surface mount components on the bottom side (opposite the USB connector) that can be broken if the board is pulled out without first lifting it up and away from the adhesive. I just successfully repaired the USB connector (solder joints on all pins were broken) and replaced a couple of the 0402 size resistors that broke off the USB board when removing it from the phone, and the phone is now charging again. Thanks for the step by step tear down - it helped save me from not destroying the M8 while opening it up!

Anybody want a new battery and charging port? Ok, only slightly used as the repair failed. When I got everything back together the LCD/backlight won't come on. I could charge the battery fine and you can feel the device responding to touch so the sensors in the display are working, but the screen will not light up what so ever. Now after a 3rd attempt to disassemble and reassemble searching in vane to find a lose connection there's a new problem, when I connect the battery lead to the terminals the phone vibrates. The only way to make the phone stop vibrating is to disconnect the battery. I can only assume this phone is now toast so it would be a shame to toss the 2 new parts...

How much? I'm having issues with the charging port not connecting to the micro used well

Hi,

I am having an issue where my phone will only charge if the cable is laying a certain direction. I have tried about 5 different chargers and the issue is the same. I had a phone repair shop replace the USB port and it did not help the issue. They tested 3 different USB assemblies to no avail. Can anyone think of another failure that would cause this issue?

Jeremy a - Reply

I have the same issue however have noticed the micro usb charging port in the image has a small shield and earthing clip/spring on top.

I think this is what's broken on my phone, but I am having problems trying to get a replacement.

Does anyone know where I could get one or the whole assembly like the one in the picture.

Does any one know what the little cables that snap to the port and the mother board are called?

Excellent guide. My repair went perfectly. The only thing I can think to add is that when you're looking for a replacement, check your device to see if it's dual antenna or single. I wasn't sure but it turned out to be the dual model. It wasn't a big deal just a detail needed when buying replacement parts.

Very useful guide, I was able to take one USB board out of a junk phone and put it into my current phone with no problems.

The Ifixit fix paid for itself after this walk through and a play station repair. Saved me a lot of time and worry!

Can I ask how you stick the speaker grills back in place. Thanks

sharon newick - Reply

awesome step by step, I was able to fix my phone! Thank you so much!!

@sharon newick, probably you have already figured ito out, but in case your are not....

I did heat the glue again for about 90 seconds, then put the speaker grills again without using any extra glue, and just in case I did heat it again for 90 seconds and put some pressure on the grills again.

They have set pretty well, so I guess that it has worked fine.

Cheers,

Fede

Thanks so much. I've never opened up a phone before but your instructions and kit made the whole process so simple and clear and have breathed life back into my phone. I am so grateful. Thanks.

I am trying to follow this guide to repair my HTC One M8 headphone jack, but I can't figure out which version of the phone I have.

CID is HTC_102 which, according to the sources I found is "HTC_GER" (OK so far, I have bought the phone directly from HTC Germany).

But which of the pictured replacement parts do I need?
