andrejkuku, just checked the service manual. The display assembly is fused together. You would need an LCD separator to remove the glass. Then you would need the right adhesive i.e LOCA OCA etc, to re-adhere the glass. You would also need an UV source for the curing of the adhesive. If you have never done this before, or if you do not have those tools, I suggest that you replace the display assembly as one unit. This will be a lot easier, yield a higher success, and is more cost effective in the long run. Hope this helps, good luck.
