See the images to better undestanding: https://imgur.com/a/6cP5W Some kind of flap got out of my tablet, it was glued with some adhesive material, but that got dirty and didn’t worked anymore so i just removed it all and try to glue it with Cyanoacrylate Adhesive. Didn’t worked, what material can i use to glue this??
Most cyanoacrylate adhesives are terrible at computer plastics. Unfortunately you may have warped or damaged the plastic by applying it, so a proper repair may not be possible. You can try Loctite 681925 but be aware that by gluing that piece back on you may be negating, or at least making more difficult, the possibility of future repairs.
