简介

按照本指南更换 iPhone 8 的 Wi-Fi 分集天线和柔性排线。这可能有助于解决连接问题。

  1. 在你开始之前,请将你的iPhone电池放电至25%以下。 充满电的锂离子电池如果被意外刺破,可能会发生着火和(或)爆炸。
    • 在你开始之前,请将你的iPhone电池放电至25%以下。 充满电的锂离子电池如果被意外刺破,可能会发生着火和(或)爆炸。

    • 在开始拆卸之前关闭您的iPhone。

    • 打开iPhone的显示屏会破坏屏幕周围的防水封条。 如果你不重新安装防水封条,你的手机将失去防水功能。

    • 卸下iPhone底部的两个3.5毫米五角螺丝。

    just how long are those screws- i turn and turn and turn and the lift off is soooo slight, seemingly insignificant…

    An. Jahnke - 回复

    I would recommend, from the very beginning, dumping all tools out of the kit (if you got it) and using that white paper tool box as a tray to organize the screws and braces in. It’s nice to work over because it catches screws well and makes it easy to see them if you drop any.

  3. 将吸盘放在前面板的下半部分,刚好放在home按键的上方。 确保吸盘不会与home按键重叠,因为这将导致吸盘和前面板玻璃之间不能形成密封。
    • 将吸盘放在前面板的下半部分,刚好放在home按键的上方。

    • 确保吸盘不会与home按键重叠,因为这将导致吸盘和前面板玻璃之间不能形成密封。

    • 如果你的屏幕已经严重破碎,可先在屏幕上粘上一层透明宽胶带,使吸盘能顺利吸附在显示屏上。你也可以直接选用粘附力极强的胶带,来替代吸盘。如果以上两种办法都不行,你还可以在吸盘上涂上强力胶,使吸盘粘在碎屏上。

    Even with using high heat from a blow dryer, I had to put the suction cup over the home button or the bottom edge wouldn’t lift at all. That waterproof adhesive is incredibly strong.

    Aaron Soderholm - 回复

    As others have said, this part really stinks, but it’ll work if you keep trying. Agree with multiple rounds of hair dryer on high (did about 60-90s each time), and with having to out the suction cup over the home button. You don’t need a big gap to pry it open - it’ll be slight …

  4. 用稳定、持续的力量拉起吸盘,使前面板和后壳之间产生一个微小的缝隙。 用一个三角拨片插入缝隙。 用于固定显示屏的防水粘合剂非常牢固; 完成这个步骤可能需要很大的力量。 如果您很难打开一个缝隙,应该对其实施进一步的加热,并上下轻轻摇动屏幕,以削弱粘合剂的强度,直到您能够打开一个足够大的缝隙来插入您的工具。

    The screen on my phone was so broken, a suction cup did not work, so I softened the adhesive with a blow dryer and used a Jimmy to carefully pry open the phone from the bottom just enough to slip a pick in.

    charguy - 回复

    Just completed a smashed screen replacement, this is probably the most time consuming part. Used packing tape to cover the screen to help create a suction surface (had to replace it a couple times because it pulls away after a purple good pulls ) Used consistent heat for about 5 minutes, then stuck a pick in the tiniest opening… and pry pry pry!

    Brian Gill - 回复

    I failed at this step. No amount of heating, pulling, and rocking opened up enough of a gap to slip in even a knife let alone the blue plastic tool. That's with a phone that has an undamaged screen - just trying to replace the battery. Apple won this round :(

    Michael Sherman - 回复

    Be really careful here. I placed a sucker to the front and rear to help lever off the screen. However, the whole thing came away much easier than I anticipated and I ripped the front part completely away from the rear, tearing all three connector cables. New iPhone required.

    Chris Wood - 回复

    Note that the opening pick they show here does not appear to come with the kit, which is a bummer! The plunger, the mini blue crowbar thing, these are too thick. I ended up using a really thin guitar pick.

    Johnny Emrica - 回复

    Following careful methods can mostly preserve the seal and reusable. Won’t be as water tight but probably still pretty good.

    Bottom edge is pull up with suction + separating tool. Use small precision scissor to cut any tape that gets overly stretched upon initial opening.

    - For the 2 long edges, use an exacto knife to separate the seal from the screen. This keeps the tape on the chassis. Go slow along the long sides. Becareful to avoid scratching the paint on underside of the screen’s edge.

    - Top corners have a thick sealed tape. Best to just use separating tool to twist it open.

    In summary, top and bottom edge use separating tool. Side long edges can use exacto knife to gradually gently separate the seal from underside of the screen’s edge.

    4 picks and an exacto knife, plus 45 minutes later, I finally got it to open! Thanks tor the tip!

    “Up from the left” means lift up the left side.

    Which is the same as folding to the right.

    Make sure you pry the battery connector off from the right hand side as shown in the picture. Theres a delicate component on the logicboard near the battery connector called a Mosfet which is linked to the battery charging software. If you knock it off accidently you’ll loose battery charging and the phone will boot loop and youll need to have it re-soldered back on.

    Hi ifixit, if you find my method dangerous, please remove it.

    After Step 17, I skipped Step 18 to Step 28.

    At Step 29, I lifted up the four adhesive black pull-tabs to expose the white adhesive side. Next, I use hot air gun and blow on the back cover of the iphone for about a minute (maybe a hairdryer will work too) .

    Warning: Don't overheat the iPhone, or you may accidentally ignite the battery.

    I think the temperature was around 60 DegC.

    Extreme Caution: Do Not overheat. I use my hand to gauge the hotness. Careful not to burn yourself or the board.

    I was able to pull out all the white adhesive tapes easily as the adhesive soften.

    DO NOT TRY this method if you are a novice or inexperience! I am not responsible if you hurt yourself or damage your iphone!

    John - 回复

    Hey John! I’m glad the repair worked out for you!

    From our research, applying heat does soften the adhesive strips, but it also causes them to lose structural integrity and break more easily. That’s why we normally suggest using heat after the strips are already broken. Removing the Taptic Engine definitely takes a few extra steps, but we feel that it gives fixers the best chance of pulling out the adhesive strips intact.

    Arthur Shi -

    I agree with John, skip 18 through 27. These are to make it easier to remove the battery adhesive. I replaced the batteries on two IPhone 8s. The first one I did all that stuff and the adhesive still broken and I had to carefully pry the battery out anyway. When I reassembled the phone the Home button no longer worked. Looking it up, this is apparently fairly common due to all the fragile wires involved in these steps. The second I skipped these steps and when I reassembled it everything worked fine. Not one of the eight (both phones) adhesive strips came out properly. I fully drained the batteries before doing the repairs. By the way, I use the virtual home button on the one phone, it’s a little annoying, but the phone is still usable if you’re not ready to shell out for a new phone.

    Gary Berman -

    I also skipped these steps. I won’t say it was entirely successful - two of the four adhesive strips broke and could not be grabbed with tweezers. But I had gotten most of the adhesive out already and the battery was quite loose, so I used a warmer under the phone, then gently slid a flat plastic blade under one end of the battery and slowly worked it up the phone. (Dental floss would have been safer-don’t do what I did, kids!)

    Matt D - 回复

    Likely can skip step 18-28 and all the risks. Battery tape is relatively removable by the following method

    - use a tweezer to pull up a corner of each tape. Then use fingers to peel back all the black tab on top of battery

    - use 2 hands. Index and thumb on both. Pull about 1/4” with one hand, hold the tension and pull 1/4” with the other hand. Alternate, go slow. Pull out all 4 tape completely. I think the pause after each 1/4” while holding the stretched tape firmly prevents the tape from over stretching to become too thin and break.

    - Don’t apply heat, I would guess that makes tape softer and break easier.

    Have tried other methods and failed in the past. Pulling too fast (tape will snap) or use a tweezer to twist/roll (sharp edges will cut tape) Anyway, just use index/thumb on both hands and alternately pull slowly

    I did do 2 iPhone 8 battery change this way. One removed all tape without breaking. Another broken all 4 tape after about 1/3 pulled so likely some factory assembly differeces.

    Daryl Maunder - 回复

    I don’t see the point in steps 18-27 if we’re only changing the battery. I pulled out the sticky tape with taptic and all this other jazz still intact. Am I missing something? Reconnecting that taptic connection cost me 5 years off my life, needlessly.

    William Mitchell - 回复

    Hey William!

    We instruct people to remove the Taptic Engine in order to minimize the chance that the battery adhesive will tear when you try to pull it out. The steep angle you have to pull the adhesive with the Taptic Engine installed dramatically increases the chance that the adhesive will break under the battery.

    Arthur Shi -

    since the sticky tape will usually tear anyway and it is no big deal, I agree stop at this point and take the battery out. Too many things can go wrong removing more screws and connecting/disconnecting all the connectors. Go to video instructions at this point. Wish I did.

    Bob McCall - 回复

    My tape tore away and now my home button does not work, which from what I see is to do with the tapic engine. It seems to be more dangerous to do that than to use heat and pry the battery out (which I had to do anyway). You should at least put in an warning/option for users.

    Gary Berman - 回复

    Hi Gary,

    The Home button connector is not related to the Taptic Engine and should not be affected by anything close to the battery adhesive. I would suggest carefully disconnecting and reconnecting the screen connectors, and make sure that there is no debris on the contacts. Be sure to disconnect the battery before you do this, or you will risk damaging the screen.

Can someone please tell me what the connector is that the wifi diversity antenna plugs into by the taptic engine, as I have a phone in parts and it is missing that connector so my wifi diversity antenna has nothing to plug into. I am guessing the person I bought it off of lost it or broke it.
