Step 5

              Splitting Motherboard from Battery Compartment
  • Make sure to have the two Phillips head screws completely removed before attempting the following steps.
  • Pressing on the small black plastic area will give you leverage to pull off the motherboard gently.
  • Do NOT flip the motherboard without first detaching the battery’s ribbon. The motherboard will still be connected by a ribbon. Only the battery’s ribbon will be detached (Marked by the red arrow in the second photo). Using a flat tool to get underneath the ribbon will lift it up allowing you to flip the motherboard over.
  • The original battery will most likely be attached to the motherboard. A spudger will be needed to detach the battery from the motherboard. Note: Use caution, gently inserting and lifting as it allows. Use of any sharp or pointed tools can rupture the battery and will cause it to burst.

Of course with a take apart of any device the waterproofing will be gone unfortunately.

Id heavily consider rewriting step 4. I almost pried the board off with the screws still attached because I read from left to right on the pictures. Device is okay but I was assuming an entire unit attached with screws was coming out of a shell. Good guide otherwise, thanks

Question - Is this the same procedure for the Frontier model of the S3?
