  • Use the iOpener to melt the glue off of the top and bottom speaker grills.

As visible from the other pictures, removing the bottom speaker grill only is sufficient.

Ok, well that was a waste of tools/time/money for the battery. Inserted the opening tool on the sides like in the picture, and pried the screen right off, the rest of the core stayed in the case. Dead screen. New phone in the mail. Thanks for playing.

Put the prying tool on the top and bottom, not the sides.

The screw to the upper right corner holds an additional small golden metall plate. Make sure to not loose it and put back when reassembling the device.

I broke the golden cable what will happen?

Is it possible to fix this broken cable?

If you leave this ribbon connector but instead disconnect the other 4 ribbon connectors (hidden under the foil tape strips, one is the one removed in step13) by simply lifting the plastic tab on them, and disconnecting all antenna cables. Then it's possible to lift up only that circuit board enough to pull out the battery from underneath.

Imho, this is easier than removing the entire circuit board assembly from the frame. I.e no need to remove the volume buttons, speaker or the upper circuit board.

it is quite easy to remove the cable (i actually removed bot cables tere was one below te silver foil just next to it. to remove it, dont pull on te cables! you have to lift up the white clip at the end of the cable using the tweezers or your fingernail then cable will fall out. dont pull using force!!

I completed the steps as described and have an issue with my display now. I tried to start the device before pressing it in the back cover to check whether it works or not. It seems to work, but the display don't. Which cable is that of the display and / or what could have gone wrong? Thx!
