Phone Won't turn on anymore

[Android Central Question]

Hello. I've occurred a problem with my Huawei p9 where I can't turn it back on. I changed my sim cards (because added my 2nd sim on which I have unlimited internet). After adding it something happened with my internet and I just decided to restart my phone. Held the power button, selected restart, pressed restart again and my phone began to do it's thing. But it didn't turn on anymore, just a black screen. When I plug it to charge nothing happens, nothing on the screen and even the small led light doesn't show that it's charging. Tried to access recovery mode by holding volume key + power button and nothing happens.. Tried to plug it to my pc using the original usb-c and there is a sound on pc that something was connected but nothing happens with an error that the device couldn't be installed. I have tried to keep it plugged to a charger and waited approximately an hour - nothing... What could have happened ? I Just restarted my phone and it died ? I don't have a huawei service center in my country and I don't feel safe bringing it to any 3rd party repair shops... I know I won't be able to fix it unless I take it to a repair shop , I just kinda want to know if anybody could tell me what happened and why ? Just for the reason if I take it to a repair shop , so they don't completely rip me off..

Thank you in advance !

Have you tried taking out the 2nd Sim card?

Yes , I did try to remove the simcard and did try to turn on my phone without the sim slot.

You should clear your cache partition and reboot after you took out the 2nd Sim.

That's the problem , I can't do that. I can't access recovery mode.
