  • 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.

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

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

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

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

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

Image 1/1: Remove the seven visible screws.
  • Look at how compact everything is inside!

  • Remove the seven visible screws.

  • Then unclip the back panel starting on the left next to the audio jack. Go slowly.

Image 1/2: Unclip the 5 ribbon connectors and the antenna cable.
  • 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.

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

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

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.

My Samsung S2 I9100G has Hard Brick Problem, for month ago i have visit technical center and they told me "the problem in the the IC" but they didn't specify which model (Power IC or Charger IC or CPU IC)!!

Iam so confused because i didn't remember where exactly the technical guy pointed to! :confused:

the expected area of the IC is the right side of the mobile, Please help me to know which part or piece should i buy to make my mobile working again

please check the photo

  • View the picture in HQ if you want to be impressed!

You can further enhance your 3g/wifi signal through the use of extension antenna -

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

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

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
