    • On the end with the buttons, remove the end cap using the flat head screwdriver to get between the rubber lining and the plastic.

    • After the cap is removed, unscrew the two 3.3mm screws using a size 1 ph screw driver.

    • Remove last white back plate to expose the back of the speaker cover.

    the metal cover looks upside down to me: holes for rubber legs and DC jack should not come on one side (like in the pictures above)

    • Remove 5mm screw in the middle of the back of the device with a size 2 ph screw driver.

    • Unscrew the two 5mm screws on each side using a size 2 ph screwdriver.

    • Open the speaker.

    • Use the prerequisite guide for removing the speaker housing.

    • Disconnect all cables that are attached to the motherboard so that it resembles the step picture.

    • Make sure that the battery is turned off before removing cables.

  9. YGtEFoxFsnSq5ERn

    • Locate the underside of the motherboard, where the square U.FL antenna connector is.

    This picture shows clearly that damaged part is the U.FL connector shown in picture. This connector is where the Bluetooth antenna is connected to, but no the antenna itself.

    https://en.wikipedia.org/wiki/Hirose_U.F...

    The connector must be damaged during an unappropriated mating of the U.FL connector, when assembling back the speaker, after some previous reapairs on this unit.

    • Use the soldering iron to desolder the U.FL antenna connector. You might need to use a desoldering braid wire to remove the excess of solder.

    • Soldering iron will be very hot.

    • Clean the PCB pads of any excess of solder with the soldering braid wire before continuing.

    • Place the new U.FL connector on the pads where the desoldered connector was. Make sure the orientation of the connector is the same as before.

    • Solder the new U.FL connector to the PCB. Avoid exessive heat and/or prolongated soldering time during this step.

Abschluss

To reassemble your device, follow these instructions in reverse order.

Be careful when connecting again the mini coaxial cable to the just replaced U.FL antenna connector, so it does not get damaged again.

Hi, nice instructions. However, the description and text on the guide are misleading. The damaged part is the U.FL connector for the Bluetooth antenna, but not the antenna itself. I have edited some text on the guide for a better description of what is being repaired.
