Removing the xLCD assembly
Unscrew four M3x10 screws mounting the xLCD to the frame.
Remove the xLCD from the frame. Put it in the front of the printer.
Do not pull on the xLCD cables!
Carefully pull of the PE Faston cable.
The position of the PE Faston cable may vary depending on your xLCD version.

Early units have the cable secured by a screw to the PE Faston connector.
Carefully unplug the xLCD connector from the xLCD board.

Make sure the USB drive is removed from the xLCD.
Remove the knob from the xLCD assembly by simply pulling it off.
Release and remove all screws securing the xLCD board.
Do not discard the PE Faston connector (brass flat plate).
Remove the xLCD-support-left (right from this view).
Carefully remove the xLCD board from the cover together with the xLCD-support-right.
Be careful not to damage the screen on the opposite side of the xLCD.

Find out which version of the xLCD you have. It can be easily recognized by the location of the grounding connection (PE / FE) on the back of the PCB:
The newer version A - the grounding point is located on the top left hole.

(version number 26, 27 and higher)

If you have this version, continue to the next step.
The older version B - the grounding point (marked PE) is located on the bottom right hole.
(rev. 0.12.2, 0.12.3 etc.)
If you have this version, continue to the xLCD B step.
The version numbers are printed on the PCB.
xLCD A: parts preparation (part 1)
xLCD A: parts preparation (part 1)
For the following steps, please prepare:
xLCD-support(1x) new part
xLCD-cover (1x) new part
xLCD (1x) you removed earlier
xReflector sticker set (1x)
The list continues in the next step...
Installing the xReflector sticker (xLCD A)

Installing the xReflector sticker (xLCD A)
Peel off one of the individual adhesive xReflector sticker.
If the sticker is damaged during peeling, there is an extra sticker in the SPARE package.
Position the xReflector sticker strip so that it lines up with one side and both the edges of the "gutter" in the xLCD-cover. Continue to lay down the xReflector sticker strip towards the other side of the gutter.
Press the xReflector sticker strip all the way into the gutter so it adheres to the xlcd-cover.

Carefully slide the xLCD into the xLCD-support, ensuring it snaps under the plastic tabs. Align the screw holes in the xLCD board with the holes in the plastic part.
Place the xLCD-cover on the xLCD, orienting it so the encoder passes through the hole in the cover.
Installing the PE Faston (xLCD A)

From the back of the xLCD assembly, secure all parts together using three 3x8sT.
The screws cut thread directly into the plastic, so there might be some resistance.
Through the opening in the xLCD-support, place the PE Faston on the xLCD with the exact orientation as shown.
Center the PE Faston in the opening and secure it with the 3x8sT screw.
The screw cuts thread directly into the plastic, so there might be some resistance.

Attaching the knob (xLCD A)
Attach and push the xLCD-knob onto the xLCD encoder pin.
Note that there is a flat part on the encoder shaft. There is a geometry on the inside of the knob that should align with the flat part to seat the knob properly.
Connecting the assembly (xLCD A)

Connect the xLCD cable to the xLCD board. Ensure the safety latch of the xLCD cable connector is up.
Make sure the xLCD cable is connected in the same orientation as seen in the picture. Otherwise, your display won't work
Slide the connector onto the PE Faston all the way.
Mounting the assembly (xLCD A)

There are four holes in the front plate of the printer's frame. Insert four 3x12sT screws through each of them from the inner side.
Attach the xLCD assembly onto the front plate. The screws should fit into the corresponding openings in the xLCD assembly.
Tighten up all four 3x12sT screws.
The screw cuts thread directly into the plastic, so there might be some resistance.

These steps are valid only if you have the older xLCD version B.  If you have the newer version A, skip to the end of the chapter.
Take the old xLCD cover.
Remove the M3n nut from the xLCD cover.
Pro Tip: Insert a screw as a handle and gently pull while wiggling it, to remove the nut.

Make sure the xLCD cable is connected in the same orientation as seen in the picture. Otherwise, your display won't work
Take the end of the PE cable with square connector. Slide the connector onto the PE Faston all the way down.
Bend the PE Faston down slightly so that it does not protrude too far from the back of the display. Curve the cable according to the drawing on the board.

Haribo time!
Haribo time!
It was a bit more challenging now, wasn't it?
Eat two gummy bears.
Follow these instructions! The exact number of gummy bears is crucial to properly completing the upgrade.
Well...
