Default [Repair Guide][New Method] How to replace dying sim/microsd/volume/power buttons

Hello, Today I will show you how to replace a problematic sim/microsd/volume/power. The reason why they can be fixed together is because they are all on the same PCB that we will be replacing.

I made this guide because I went snowboarding and I dropped my phone in the snow. I tried the rice trick but after that my power button was still dying. I looked up prices for getting a professional to replace it and it was around $60 for a part that costs $10 MAX. So i just bought the part off of ebay and documented my process

EDIT: if the pictures don't show up, just right click and open in new tab for now
EDIT: There is now no need to remove the motherboard to solve this issue

Tools I Used:
  • Small flathead
  • Small Philipshead
  • Thin pointy object
  • Scissors

1) Remove these Screws only because the others are not required

https://www.dropbox.com/s/3dw6lf5rtq...414_153856.jpg

2) Use the flathead to pry off the cover from the frame

3) Use the flathead to pry off the cover from the frame

4) This is what it should look like

https://www.dropbox.com/s/rcbyzvql8u...414_151627.jpg

5) Remove the silver screw with the philips head and put it in a safe place
https://www.dropbox.com/s/0u1yl88w08...414_151702.jpg

New "easy" method
 

6) You DO NOT need to remove all the connectors, only the ones in red
https://www.dropbox.com/s/5cgxcq2ocm...20-%20Copy.jpg
Take note that the electronic above the sim card slot just needs to be peeled off gently, It is NOT a connector but it does rest on top of the PCB.
Also, you'll need to pry off the vibration motor (the circle to the right of the Sim card slot) as it is glued in


7) This is what the PCB looks like when separated from the motherboard
Note: your motherboard will still be in your phone, i just wanted to shop you what both parts look like
https://www.dropbox.com/s/6ysyid9eu2...414_152536.jpg

8) Get out your new PCB
https://www.dropbox.com/s/6130c74hcx...414_152619.jpg

If The PCB you ordered did not come with the shielding then follow these steps
Note: Your motherboard should still be in your phone
 

8.a) Remove the shielding from the back of the original PCB, be careful of the glue to not damage any components
https://www.dropbox.com/s/nfpuwzf3om...414_152657.jpg
https://www.dropbox.com/s/73sbx0k32f...414_152731.jpg

8.b) Now, put the shielding back onto the motherboard, it should fit into place nicely
https://www.dropbox.com/s/li966nnquj...414_153037.jpg

8.c) Take out your new PCB and connect the connector to the motherboard before, placing it on the shielding
https://www.dropbox.com/s/mn97igyuir...414_153154.jpg
Make sure everything is secure

8.d) Take out your new PCB and connect the connector to the motherboard before, placing it on the shielding
https://www.dropbox.com/s/mn97igyuir...414_153154.jpg
Make sure everything is secure



Old Method by removing mother board
 
Procedure:
Follow the steps from the guide here up to Figure 3.4

8.a) After removing the motherboard, remove the following connector
https://www.dropbox.com/s/bsgwmyf6t1...414_152518.jpg

8.b) Now just pry off the PCB from the motherboard, be weary of the adhesive
https://www.dropbox.com/s/6ysyid9eu2...414_152536.jpg

8.c) Get out your new PCB
https://www.dropbox.com/s/6130c74hcx...414_152619.jpg

8.d) Remove the shielding from the back of the original PCB, be careful of the glue to not damage any components
https://www.dropbox.com/s/nfpuwzf3om...414_152657.jpg
https://www.dropbox.com/s/73sbx0k32f...414_152731.jpg

8.e) Now, put the shielding back onto the motherboard, it should fit into place nicely
https://www.dropbox.com/s/li966nnquj...414_153037.jpg

8.f) Take out your new PCB and connect the connector to the motherboard before, placing it on the shielding
https://www.dropbox.com/s/mn97igyuir...414_153154.jpg
Make sure everything is secure

8.g) Slide the motherboard back into place inside the frame
(Make sure not to damage any connectors by safely getting them out of the way BEFORE putting in your motherboard)
https://www.dropbox.com/s/ojvh1vftm6...414_153415.jpg
https://www.dropbox.com/s/f3k5f1c7qe...414_153420.jpg


9) Reconnect all of the connectors you previously disconnected EXCEPT the volume and power
https://www.dropbox.com/s/v0oyeoaswk...414_153602.jpg

10) Now carefully slide in the power and volume buttons into their correct spots
(I used the flathead the push the rockers out of the way to slide in the buttons)
https://www.dropbox.com/s/l94dfverf2...414_153832.jpg
Now test the feel of the buttons before putting the Screw back in. (You should hear the tactile feedback)

11) Screw in the screw you removed to get the motherboard out
https://www.dropbox.com/s/3dw6lf5rtq...414_153856.jpg

12) Put the cover back on (do NOT put the screws back in yet) and see if the all the sides close properly
https://www.dropbox.com/s/e4sc0thp8i...414_153954.jpg
https://www.dropbox.com/s/wyob0xuxaq...414_154002.jpg
https://www.dropbox.com/s/7x46humbis...414_154010.jpg

13) Well crap, i have a bump
https://www.dropbox.com/s/3h6mejmug7...414_154015.jpg
https://www.dropbox.com/s/69w769ubiz...414_154131.jpg
Time to backtrack and see what is not seated properly


14) After all that is done and is properly fitted, Put in your sim car, micro sd, and battery
(Do NOT put in the screws yet)
https://www.dropbox.com/s/it26v6h776...414_154143.jpg

15) Now power on and see if it works
https://www.dropbox.com/s/fumzxsuewn...414_154158.jpg
(Mine did, I was so happy I could cry!)

16) After it power on, test all your buttons

17)Test Cases:
  • Press power button once to see if the screen turns off
  • Press the power button to see if the Screen wakes up
  • Press the volume up to see if the volume increases
  • Press the volume down to see if the volume decreases
  • Check your sim connectivity, should have bars
  • Check your micro sd card by going to Setting>Storage>SD Card
  • Check your cameras
  • check your sound

If something does not work, backtrack and check all of your connections.
If your power or volume buttons don't work, check the PCB connection. If it still doesn't work, you might have received a defective PCB like I did (My volume buttons didn't work). Contact your seller and ask for a replacement for your defective item (I got mine for free and now everything works).

18) If everything works, NOW screw in your remaining screws and close her up and enjoy your day!

Default vibration motor?

hi i have been following your instructions and everything has been going very smoothly. however, i cant figure out how you take out the vibration motor from the old pcb and put it into the new one. do you simply yank it out? i dont want to break anything, thanks!

No do not yank it, the wires are sensitive, I used a soldering iron and heated the contacts up enough to the point where the wires were able to be pulled out. Then I soldered it to my new one. (Remember which wire goes to which contact)

Its honestly really easy and a good skill to learn, but there are PCBs with the motor already attached on eBay if you ever need it.

DONATE TO ME
Awesome walkthrough.
I might use it one of these days as my power button is pretty much gone.
