Watching this thread with interest.
have myself completed the removal of 4 screens. Unfortunatly the first 2 were unsuccessful.
Well they do say practise makes perfect.
Anyway regarding the oca or glue.
I just wanted to share a smidgen of knowledge I have about that.
I believe (cant be certain) that the material is called 'pmma'.
There is another substance called pmma but it is banned as one of those party drugs.
So def not that one.
Butnormal PMMA is used a LOT in the semi -conductor industry. It is a rubber like substance, optically clear that is excellent for making rubber casts of fine detail. It can imprint the trackes on a cd for example.
I believe this is what they are using. under the front glass.
