Edit Step 2  ¶ 

  • Look at how slim the phone is! Only 8.49mm thin!

  • Back cover is flexible but don't worry it will not break. It also has a nice texture to it.

Edit Step 3  ¶

Edit Step 3  ¶

Edit Step 5  ¶

Edit Step 5  ¶ 

  • Removing the motherboard is as simple as it looks !

  • Unclip the 5 ribbon connectors and the antenna cable.

  • Then remove the 2 small black screws.

  • Don't forget to unglue the volume flex and power flex, they are attached to the motherboard. Otherwise the motherboard won't come out easily like it should.

Edit Step 6  ¶

Edit Step 8  ¶ 

  • This EMI shield is nearly a heat sink.

  • Should be useful with a 1.2GHz dual core under it!

Edit Step 9  ¶

  • The front-facing camera and the light sensor are a single part.

i was just wondering,

the volume key

how do you solder it on if you ripped it off when you took your phone apart?

and, is it soldered on...?

Ali Wannous, · Reply

new keys are easy to find online, and you'll need to use a fine tip soldering iron to put the new one on

hi my ribbon cable (motherboard) is ripped how can i get that repaired, any idea's as i have valuable data on that phone..

Shaan Awaz, · Reply

The plastic cover is elastic, but hardly fragile. You can bend it 180° and it doesn't break.

Roy Weiss, · Reply

True, I tried to edit the guide to show this information but was denied!

funkmasterta888,

I agree about the back plastic cover, it is very flexible and doesn't break that easily.

alexman98, · Reply

Have a look at this video that shows how durable the battery cover is! Thin, light and durable, now we're talking!

http://www.youtube.com/watch?v=ErXqnQKs-...

A video about this amazingly thin, light and flexible battery cover! Try and beat that aluminum!

funkmasterta888, · Reply

pry off the glued power and volume buttons before lifting the board because too much pressure will tear the ribbon from the board leading to much heartache

John McGyver, · Reply

I have a question. Where is the internal SD card located? Is it integrated into the motherboard?

GrowlyCub, · Reply

Thanks. I tried an external antenna in the port under the cover, to the top left of the battery, and now I get "mobile operator not available" when the antenna isn't in. I've read that a factory reset won't cure this but if I replaced the pcb part that should be me "back to normal"? Thanks

nathanjh13, · Reply

I fixed it. Insert a SIM card from another operator, select "Automatic" from the mobile networks and the phone will work. Reboot with your regular SIM back in and choose "Automatic" again and back to normal. People elsewhere say you need a new motherboard (or send to Samsung etc for repair) as it's not possible to solve via software. I tried another SIM to test if it was hardware or software related and it most certainly is solvable via software. Unless I was very very lucky, which I never am.

You can further enhance your 3g/wifi signal through the use of extension antenna - http://telcoantennas.com.au/site/patch-l...

Anyways to replace this camera module with Galaxy S3 camera module?

Tai Li, · Reply

Can I replace the front camera with another 8 MP back camera?

Tai Li, · Reply

Hello. How do you actually unglue the USB flex cable ? Do you use chemical products, heat, or simply tear it ?

rgauthierventre, · Reply

Can you please describe how to replace the home button and the associated OEM Flex Cable Keypad Button Ribbon? I have the home button acting like it is always pressed and I tried to change everything in the phone (hw and sw) but it's still not working right :(
