Introduction

In this guide, we will show how to replace the touch screen on a Nokia Lumia 520. It’s the innermost part of the phone and requires disassembling the entire device.

I can't quite see from the pictures. .

My sons Lumia has a headphone jack tip stuck in the headphone socket. .

I've tried various methods of removal, to no avail.

Is there a hole at the bottom of the headphone socket that would enable me to "poke" the stuck tip out ?

Regards

Josh

The screws actually have T5 heads. A T4 will work, but fits loose.

priorytools: There is no hole in the bottom of the headphone jack assembly.

I bought a T5 screwdriver based on this information but found it was too big for the screws

I ordered a T4 screw driver and it fitted perfectly

Good Day,

I would like to thank Nico and the iFixit-team for this very informative description. It helped me big time today!

Yes, I can confirm that the screws are T5.

There is a minor error in the text under Step 3 — Remove the Screws:

"The phone is assembled with eight screws. Using the T4 Torx Screwdriver, remove all eight screws from the back cover. The four small thread screws (red arrows) are fixed on the LCD panel. The four big thread screws (blue arrows) are fixed on the touch screen's frame."

Actually, there are *three* small thread screws and five big thread screws. The photo is correct. Sorry for the pedantry :-)

Cheers,

M.
