[Q] Htc one m8 black screen, won't boot up PLEASE HELP

[Mexson]

So, I tried to restore a backup from TWRP. During the process, the system and cache were restored fine, but couldn't restore the data (for some reason, it said failed), so I figured it's alright, I'll just have to install all the apps again, no big deal. But, after I clicked the "reboot system", the screen went off and never turn back on.

I can't get in bootloader screen in any way, I haven't tried the Vol up + power button for 10s, and the vol down + power button, and the 3 button all together... Nothing works.

When I press the power button normally, nothing happens, not even the Htc logo screen.
When I plug it in, it only shows the battery charging icon. So I tried the buttons combination again (coz I thought at least the screen turns on now), but still, nothing happens, just the screen switch between black and the charging icon.
So, I left it charging overnight, and tried the buttons combination again, nothing works still.
Now I have no idea what to do, can anyone please help me?

Only thing what you need is that computer recognize your phone, because when It doesnt then you should take your phone to local phone repair.
