Oscal Tiger 12: Teardown

Teardown

Introduction

This is just a basic how-to-open guide for the Oscal Tiger 12 smartphone, and not a complete disassembly.

I also made a mistake during opening which broke the fingerprint sensor. You should avoid doing so, and I will outline this mistake in the step it is present in.

    • Begin by heating the back panel (where the cameras are).

    • I use a heating pad set to 100 Celsius for this job. Usually put it on before it's heated, then let it sit 6-7 minutes at 100.

    • You can use a heat gun instead. Just make sure to heat all the surfaces enough. How much enough is, you will have to find out.

  2. There are 3 steps dedicated to this, as iFixit allows only up to 30 second videos.

    • There are 3 steps dedicated to this, as iFixit allows only up to 30 second videos.

    • Once you're done heating the back cover, it's time to remove it.

    • I start with a bit of a box cutter blade bit that I've wrapped in insulating tape. If you decide to do the same, do be careful when pushing it deeper in. It is very easy to leave scratch marks on the inside of the back cover.

  3. After I get a bit of a start, I slip Jimmy in and force a bit larger gap.

    • After I get a bit of a start, I slip Jimmy in and force a bit larger gap.

    • The back cover is very flexible, but has paint on the inside part of it, which can easily be scratched off. This damage is purely cosmetic and can easily be covered by a phone case.

  4. After the gap is large enough, I use a plastic card to open the rest.

    • After the gap is large enough, I use a plastic card to open the rest.

    • Be significantly more careful than I was on the side with the fingerprint sensor (Left if the phone is face down, camera up, and right if the phone is face up). I would recommend only detaching the other side using tools, then simply lifting it.

    • Not going to lie, I never catch her on the top.

    • Now, remove the camera cover. If you have a heat gun, heat it prior.

    • It is simply glued on.

    • Remove the marked screws.

    • Slip something in between the LCD's frame and the external frame. Jimmy should work, but it's easier to get a start using something sharp.

    • Remove the fingerprint sensor.

    • This black cover (thermal diffusor?) is glued onto the battery with a very thin layer of adhesive.

    • Remove the cameras from the motherboard, then lift the black cover over the motherboard to expose the battery and LCD connectors.

    • Disconnect them, then remove the 2 screws that hold in the motherboard.

    • I used to mark these (to remember where they go), but I've noticed they're pointed to by 2 very small arrows on the motherboard.

    • Now, remove the motherboard.

    • I recommend using a plastic spudger where marked in picture 1 to get some leverage. It's usually stuck quite a bit by some thermal paste that almost glues it to the frame.
