    Looks easy but doesn't work. No one has a plastic opening tool. Using fingernail, you can press SIM card into slot but it does not pop out so you can remove it.

    Laurie McWherter - 返信

    I agree with the comment above

    I also don't have a plastic tool and my finger nail won't pop the card out.

    • ミッドフレームはミッドフレームのクロムベゼルの裏側に、ディスプレイアセンブリに幾つかのプラスチッククリップで止められています。

    • デバイス本体サイドにある音量ボタン側から作業を始めます。ディスプレイガラス周辺のクロムベゼルと大きなクロムの淵部分の間にプラスチック製の開口ツールを差し込みます。この両側の繋ぎ目を探してください。

    • 開口ツールを繋ぎ目にそってスライドします。進みながらプラスチッククリップを外します。

    • こじ開ける作業は大変丁寧に作業を進めてください。一方で、プラスチッククリップを軽く外す程度にします。クリップを大きく曲げてしまうと、ミッドフレームのベゼルにある幾つかの薄いポイントが割れてしまうことがありますのでご注意ください。

    I used same tool as in the photo and i broke the display. I think you should use a very thin plastic tool, such as a credit card but even more thin and flexible.

    I purchased a blue plastic opening tool(AKA: Spudger) and was able to remove the midframe from the display assembly as per the Step 7. I had to hold the cell phone firmly in my left hand while I gently forced the spudger between the chrome bezel and the midframe with my right hand and heard plastics clips separate and saw the midframe start to separate from the display assembly. Don’t be afraid to get that spudger in and just gently go down the side of the phone and you will hear the plastics clips detach and the midframe to separate more and more until you are able to separate them 100%. I started at the volume button side of the phone in Step 7 and ended at the power button side in Step 9.

    Terry Crawford, Jr. - 返信

    This blue Case Opening tool has a less rigid edge that is kinder to trim than the hard black Spudger shown in later steps. I was glad to have the right tool on hand at this step. Use it as a wedge and slide it along the gap.

    • 開口ツールをデバイス本体上部周辺でスライドさせながらクリップの残りを外し、ディスプレイアセンブリからミッドフレームを外します。

    • この時点で、再びプラスチックの開口ツールをデバイスの全周辺に沿ってスライドさせます。プラスチックのクリップを全て外したか確認します。

    On my phone, there was another clip holding the white midframe to the battery compartment, in the middle of the top edge of the battery compartment, near the battery contacts. If you don't release that before removing the midframe, it is easy to break.

    My Sprint S4 was slightly different then the one pictured above but I just completed this repair in under 10 minutes.. It would have been slightly quicker but fooling around with those little screws can be irritating if you have big hands.

    Michael Willis - 返信

    Just did this on my S4. Instructions were extremely helpful, but I had to remove a screw (step 10.5?) to remove the upper display assembly bracket. Other than that, flawless! Thanks!

    JackieME - 返信

    The 3rd image of the 11th step shows that when the midframe is removed, some parts come along with it (at the bottom part of it). What are these parts? should they be removed too and placed in the new midframe? Are they easy to remove?

    I had to use a metal scalpel to get in between the USB Port and the USB Port Bracket and it went flying off. richporctor post above on August 15 was right. Be prepared! All in all, the instructions will get the USB Port Bracket off the USB Port.

    Tweezers were much easier to use. You need to slide them in pretty far in order to get the right leverage.

    • ソフトボタンケーブルをUSBボードケーブルから外します。

    • USBボードケーブルからアンテナケーブルコネクタも外しましょう。

    • 使用しているキャリアによっては、これ以外に追加のアンテナケーブルがある場合があります。この時点で追加のケーブルが切断できそうであれば切断しましょう。

    My 4G LTE phone has a 4G antenna on the left side of the device that is under the USB cable and connects to the left side of the USB board. Be sure to disconnect this as well if you have a Verizon or Sprint phone.

    There's no mention of the need to detach the blue wire on the right side of the phone at this step. It's fairly obvious, but it might cause some confusion for the uninitiated.

    After changing the port I got the message battery temperature to low charging paused.

    This is one of those generic message computers use when it doesn't know what is wrong.

    So I cleaned with alcohol and q-tip the two gold contacts that are located in the mid frame. They touch the two power contacts located on the USB port board and this cleared the low temperature message and phone is charging.

    With the blue plastic opening tool(AKA: Spudger) I was able to gently disconnect the soft button cable form the USB board cable and disconnect the antenna cable connector from the USB Board as per the instructions in Step 15. There was no additional antenna cable on the Samsung Galaxy S4 Verizon Service phone.

    • USBボードは軽く接着剤で固定されています。

    • 使用しているキャリアによっては、USBボードの裏側に追加のアンテナケーブルがある場合があります。慎重にこじ開け、引っ掛かる場合は作業を止めてください。

    • USBボードの下にスパッジャーの平らな部分をそっと差し込み、ボードを接着剤から慎重に剥がしましょう。

    • ゆっくりと差し込み、慎重に剥がしてボードを曲げないようにご注意ください。

    As I inspected the USB board I noticed on the left hand side a gold antenna connector with a red colored wired connected to the USB board. I gently disconnected it using the blue plastic open tool(AKA: Spudger) and it popped off ok. You will now be free to take out the USB Board from the display assembly. If you ordered a Samsung Galaxy S4 Charging Assembly (Verizon) part, you can just take out the USB board from the display assembly . I noticed that you are NOT suppose to take out the soft button cable, just disconnect it from the USB Board Cable. You then insert the new Samsung Galaxy S4 Charging Assembly (Verizon) part and place the soft button cable over the USB Board Cable and connect it.

I found this guide excellent and it is very easy to do. I didnt have the plastic opening tool but I do have a long thumbnail. It worked very well.

Too bad the replacement board I got has a defective soft button connector. I had to disassemble the phone 3 times. I thought I did It wrong the 1st time. Opened the phone a 2nd time to check.... closed the phone... nada.... USB changer works but no soft keys... put my old board back in to check the soft buttons and they work. Sent an email to the company that I bought the board from... still no answer after 24hrs. If I still have no answer by the end of the week I will post which company sold me the defect board so no one else gets burned from them. I will then try to unsolder the USB from the new board to replace the USB on my old one.

This guide needs an update as it does not include the 4G antenna on the left side of the device that is under the USB cable and hooks up at the bottom left on the USB board up to just beside the USB connector above the battery. Pictures 12, 15, & 16 will need updated to show this cable.

rnbhays - 返信

To follow rnbhays' comment about the antenna connector on the left, it is specifically for i545 Verizon models.

I strongly suggest people to disconnect both left and right cables from the USB board prior to removing it. While doing so, my tool slipped and I accidentally broke the left cable. Thankfully I was able to crimp the connector back on the cable with tweezers and a magnifying glass 'til I get another cable ordered.

Alex - 返信

It also applies to the Sprint version as well. I have an LTE cable on the left side, and had to be very careful purchasing a replacement part to make sure it was the right one.

Ordered the part from iFixit. I figured the fact that it was fully tested and guaranteed for a year was worth the extra cost. The repair went smoothly with no issues.

I changed my charge port because the little pin in the charge port was damaged and it was a pain to charge but now I get a "charging pause battery temp to low" notification. I've changed it now 4 times thinking I just keep getting duds. anyone know what i'm doing wrong? I've followed every step.

Is there a special part number for the S4 T-Mobile phone? If not, which part number from the listed parts for this repair do I need?

lsoldano - 返信

I have a Samsung Galaxy S4 that was no longer accepting a charge. I've changed out the USB board. I plug the phone in with the device powered off, it vibrates and turns on showing the battery with charging signal, then reboots. It continues to do this. When I power the device on, it remains powered on, but does not accept a charge. I've reopened the phone and checked the install. Same thing occurs. In case of a defective part, I changed it out with another part. Device powered off and plugged in, does not react. Device powered on and plugged in, does not charge.

Any other suggestions at this point?

Stacy Moffat - 返信

Great guide. The bit about removing the soft button cable could be clearer, it plugs on to the USB board flexi circuit.

Thanks. It's detailed explaining and guided me to replace the part safely.
