Huawei P9 - display can't be solved?

Unfortunately, I have failed in trying to disengage the display from the Huawei P9 to fix it.

In the video (

the display is comparatively easy to open. Since my display is broken, especially at the bottom, I had to dodge by a suction cup on this cable holder (https://www.amazon.de/AGPTEK-Kabelklemme-Kabelbefestigung-Drahthalter-Verstellbare-50-St%C3%BCck/dp/B06XTYW9TZ/ which then held well. Nevertheless, it was only with great force possible to lift the display minimally on the lower side. Even under the influence of warm air of a hair dryer, there was no real success. (about 45 seconds on it)

Has any experience with it or has suggested solutions? I'm really slow from the ideas, as I have already handled with the most varied tools, mainly from this kit (https://www.amazon.de/Zacro-Smartphone-Multimedia-Kleinger%C3%A4te-Mikrofasertuch/dp/B01EYGZ5SM/

(SIM card slot and the two screws at the bottom, of course, I have removed)

Did you have a hair dryer or a hot air dryer?

that can partly lead to enormous differences:-)
