Wat je nodig hebt

  1. Samsung Galaxy A53 5G Daughterboard Replacement, Heat the back cover: stap 1, afbeelding 1 van 1
    • Prepare an iOpener and apply it to the back cover for at least two minutes to loosen the adhesive underneath.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are both susceptible to heat damage.
