Ok, I made it, and if you want to know - glue is very hard to be cleaned from theese layers - it stay in theese little scratches. However I replaced almost all layers from another broken LCD and despite fingerprints and some ashes, it is working, but with many brighter spots. Still better than loca glue, thanks mate!
I have the same problem with my Z2. I'm wondering how possible it is that I will positively remove LOCA from theese layers? Is it 80% or about 10% :P And what can I use to clean glue? petroleum ether will be ok?
