HTC One M8 Kopfhöreranschluss / Mikro USB Platine tauschen

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?

My phone have a problem from sim card rejected ,

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.

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

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

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.

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

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...

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!
