  • Press to eject the tray.

    • This may require a significant amount of force.

  • When reinserting the microSD card, ensure that it is in the proper orientation relative to the tray. The contacts should be inserted first and face to rear side.

  • It is normal, that the microSD card doesn't stay on it own inside the tray. It is also not completely trivial to place it correctly flat inside the tray.

Be sure to remove the SIM tray and memory card tray prior to removing back case! Bent mine because that step was missing.

The black plastic piece that runs across the top is very thin and is stuck on with very strong tape.

Work a plastic opening pick around the perimeter of the device to separate the rear case from the display assembly. The SIM card tray and Micro SD card tray must be removed before the back cover can be removed. Be careful around the power and volume buttons, as they are fairly delicate.

  • Be careful when separating the body from the display assembly, as the rear-facing camera may be stuck to the body with adhesive.

The SIM Card and SD Card's need to be removed before the case will come apart.

Disconnect the remaining three ZIF connectors. The third ZIF connector is mostly underneath the motherboard. When reassembling your device, make sure it is placed back underneath.

Great guide just one crucial warning missing! When removing the battery which is underneath the power/SD/volume cable make sure you see that and carefully remove the battery without tearing it apart! Had to learn the hard way. Fortunately it's replaceable..

    • The motherboard is secured with adhesive, so you may need to use an iOpener or heatgun to loosen the adhesive. Refer to the iOpener guide for info on this.

Mine did not have any adhesive.

Took me almost 2 hours, but in my opinion it's not 'very difficult', it's not easy but it's doable for sure.

half this guide can be skipped, all you need to do is:

disconnect the battery

disconnect LCD flex and peel off the conductive tape

heat LCD up

Slide a thin plastic tool in under the LCD (can be anything, like the hard-ish plastic used in blister packs), there is only tape along the sides, start at the top center of the lcd. Seriously just slide it down and cut the tape (it's super strong!)

Now just lift the battery up about 3mm (on the same side as the lcd flex) and slide the lcd out, flex and all..

Total repair time is HALVED and you don't mess up the rest of the RF shielding tape.

Total of just 4 screws need to be removed!

:)

hope this helps :)

Is it possible to use this guide to replace the front cover? I'd like to know before I get into a mess I can't get myself out of!
