Introduction

This guide demonstrates how to replace the I/O board, which includes the charging port and the headphone jack, of the OnePlus Nord N200, also known by its model number DE2118. This guide is designed to provide you with a step-by-step approach to replacing the I/O board, ensuring that your device can charge efficiently and connect reliably to your headphones.

If you are experiencing difficulties in charging your device, if the connection is frequently interrupted during data transfer, or if the charging cable does not fit securely, it might indicate that the charging port is damaged or faulty. These are common signs that a replacement is necessary. Symptoms indicating the need for a headphone jack replacement include intermittent audio or static when headphones are plugged in, the device fails to detect the headphone connection, and physical damage to the jack itself. For more detailed diagnostics, check out our troubleshooting page.

You'll need a set of precision tools and a new charging port compatible with your phone model to complete this replacement.

Important Tips and Warnings:

Ensure your device is turned off before beginning any repair. This is crucial to prevent any electrical shorts or further damage to your phone.

Always back up your data before starting the repair as a precaution against unexpected complications that might lead to data loss.

Step 1

Due to its surface, the suction tool won't hold onto the phone's rear glass. A thin slicing tool is required.
Insert the Jimmy into the seam between the rear glass and the midframe at the bottom edge of the phone to create a gap.
This may require some force.
Leave the Jimmy in place for a few seconds to prevent the adhesive from resealing.

Step 2

Insert an iFixit opening pick into the gap you created with the Jimmy.
Slide the Jimmy around the phone to slice the adhesive.
Insert a second iFixit opening pick at the spot you have sliced open to keep it open.

Step 3

Slide the iFixit opening pick along the top edge to slice the adhesive.
Start prying the back plate off the phone.

Step 4

Remove the back cover.

Step 5

Use a Phillips #00 screwdriver to remove the sixteen 3.6 mm-long screws securing the midframe.
The orange circle represents a hidden screw that also needs to be screwed out. (At first glance it may not look like a screw).

Step 6

Gently insert the Jimmy to create a gap between the midframe and the top of components in the bottom case.
Slide an opening pick around the edge of the midframe to slice the adhesive.
Use the Jimmy to pry off the midframe of the phone.

Step 7

Use your hands to finish prying open the midframe off the phone.
Watch out for the fingerprint reader cable when taking off the back tray as it is still connected. If you are not careful, it could be damaged.
Pull the midframe off of the phone and lay it to the side of the phone.

Step 8

Place a spudger or an opening tool under the connector's edge and pry straight up to disconnect the fingerprint cable connector.
Move the fingerprint reader cable to the side along with the midframe.

Step 9

Remove the midframe.

Step 10

Before you start with the repair, make sure to disconnect the battery from the charger to avoid damaging your phone.
Place a spudger or an opening pick under the connector's edge and pry straight up to disconnect the battery.
Make sure to pry under the edge of the connector itself, and not under the socket on the board. Otherwise, you risk permanently damaging the socket.
Work carefully: don't pry on or accidentally scrape any small, surface mounted components on the board.
To reconnect, align the connector carefully over its socket and press down with your fingertip—first on one side, then the other—until it clicks into place. Don't try to force the connector into place. If you're having trouble, reposition it and try again.
Don't press down on the middle of wider connectors until they're fully seated. If misaligned, the connector or the pins underneath can bend or break, causing permanent damage.

Step 11

Insert iFixit opening pick under speaker assembly.
Lift up the iFixit opening pick to pull out the speaker assembly out of its tray.
The speaker assembly should come out easily. If not, check if you missed a screw.

Step 12

Remove the speaker assembly.

Step 13

Place a spudger or an opening tool under the connector's edge and pry straight up to disconnect the battery.
Make sure to pry under the edge of the connector itself, and not under the socket on the board. Otherwise, you risk permanently damaging the socket.
Work carefully: don't pry on or accidentally scrape any small, surface mounted components on the board.

Step 14

To disconnect the black coaxial cable connector, slide a thin, ESD-safe pry tool or angled tweezers under the metal neck (as close to the head as possible) and lift straight up from the board.
Start with the black coaxial connector as it is safer to disconnect first.
When working with these connectors, it's key to always lift the head straight up. If pried on at an odd angle, you risk breaking the socket off of the board underneath.

Step 15

Slide a thin, ESD-safe pry tool or angled tweezers under the metal neck of the white coaxial cable connector (as close to the head as possible) and lift straight up from the board.
When working with these connectors, it's key to always lift the head straight up. If pried on at an odd angle, you risk breaking the socket off of the board underneath.
Reconnecting these can be tricky. Use tweezers to hold the connector in place over its socket and gently press down with your finger or a spudger—the connector should "snap" into place. If you're having trouble, reposition the head and try again.
Don't try to force the connector into place or you may permanently damage it.

Step 16

Insert the iFixit opening pick under either side of the I/O board.
Use the opening pick or a spudger to pry under the I/O board and remove it from the case.
