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.

I agree with the comment above

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

How much cost will be on replace a midframe

I'm seeing midframes available on Ebay for around $10.

The midframe is secured to the display assembly by several plastic clips behind the chrome bezel of the midframe. The next few steps will guide you through separating the clips to free the midframe. Starting on the volume button side of the phone, insert your plastic opening tool between the chrome bezel around the display glass and the larger chrome border piece.  Look for the seam between the two.

  • Slide the opening tool along the seam, separating the plastic clips as you go.

  • Be very gentle whilst prying, and pry only enough to separate the plastic clips—there are several thin points in the midframe bezel that may crack if you bend them too much.

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.

Continue prying around the corner of the phone. Slide your opening tool along the seam between the midframe and display along the bottom of the device, releasing more of the plastic clips.

Continue sliding the opening tool around the top of the phone, releasing the last of the clips and freeing the midframe from the display assembly. At this point, you may want to run your plastic opening tool along the entire perimeter of the device again, to make sure you've released all of the plastic clips.

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.

Just to be sure does the rear frame referred by etradesupply is the same as the middle frame? I' planning to refurbish the side panel because of the dents and scratches but I just want to make sure I'm buying the right thing. The etradesupply referring the housing as rear and front housing so Im not sure which one correspond to the middle frame. Below is the link to the website http://www.etradesupply.com/oem-samsung-...

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 - Reply

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 - Reply

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?

Does it matter which motherboard I get? Why are there different prices depending on the phone company?

Disconnect the headphone jack assembly cable connector. Disconnect the display/digitizer cable connector. Disconnect the antenna cable connector.

Replacing the S4 advance display, I've broken the plug on motherboard of the antenna, which part should I replace now ?

Second question, when display replaced, the "home" buttton was working just as the "return", did I make a wrong thing ? (perhaps ending the daughterboard) and what is the countermeasure ?

LEMEUR JMarc - Reply

My model had an antenna connection next to the usb board connector in addition to the antenna connection near the display cable connector.

Drew - Reply

That's point a, on the daughter board (where the USB is located is point b. You must connect it from a to b

Same as Drew. My model has two antenna connections. One as shown, and one on the left side of the motherboard.

Gavin McMorrow - Reply

Mine does too. I can't get that one to reconnect. What is it?

I could not get the screen connector to fit on with the motherboard assembly in place. I had to remove the motherboard assembly, attach the screen connector, and then carefully replace the motherboard assembly, with the screen connector still attached..

As Sam Lionheart states at the end of this guide, some of these phones have an additional antenna on the opposite side of the phone. Be sure to detach it before removing the motherboard.

Gently remove the motherboard. Hold the motherboard by its edges to prevent ESD damage. Be careful not to snag it on any cables as you extract it from the display assembly.

I believe in Step 17, it should read as "rear facing camera", not "front facing camera".

Could either be the battery or a software problem. If it's not the battery then downlad your stock rom and flash it with odin.

Hi I have a Samsung Galaxy S4 that wont turn on or charge, I've been told its the mother board by a Samsung engineer whos checked the phone over. If the motherboard can be changed will I still keep all of me texts, contacts, pictures etc that are stored on this phone or will they be lost? I've not uploaded them to the cloud and worried Im going to loose everything. Please help Thanks!

paulablack - Reply

Paula, if you did not store the information on SD card, that information resides on the motherboard'smemory chip. You may want to try KIES to be able to recognize your phone and download the information to your computer.

Sam, Thank you very much for this tutorial with pictures. I had bricked my Samsung S4 recently and could not revive it. I was successfully and economically able to replace the motherboard and revive the phone. I also appreciate comments about dual antenna - my phone had them - and cautions by other readers.

Hi a question for paulablack and Prashant, I have the exact same problem as paula. But if my phone can't be powered up, then it will not show up in kies would it? Paula, did you solve your issue?
