Awesome guide! I finished it, and now I have a fully working X

Just one thing: the video and the instructions differ on step 20, making the rest unnecessary according to the video guide. On the other hand, it may facilitate taking the glue off, especially for newbies.

:( Sorry only now I saw your answer

Found it cheaper at Amazon

Look at the comment section before you proceed. It is possible to finish the process without unplugging the board or other components. Be aware these are user’s comments and not the official guide.

Good Luck!

@Ian Jeffreys, so what did you do in the end, the 12v trickle charger or the 18h MBP charger?

The correct way of taking off the adhesive is not how it's shown in the picture (that is exacly how I broke both strips): it should be pulled out by tearing it away and right (to the speaker direction) and as flat as possible, and as the strip grows thinner move up but still pulling "down-right" until all comes out, same movement: " down-left" for the left strip
