[Solved] Bricked m4 aqua after screen replacement - Sony Xperia M4 Aqua

Hello,
I've recently bought an m4 aqua with a broken screen, but the whole phone was working normally.
So I replaced the screen but now the device won't turn on.
The thing is:
1) No reaction on pressing power button
2) No reaction on vol up+power button and the small button hidden under sdcard slot.
3) When connected to the charger/usb the screen goes on to sony logo (red led) and then to charging screen (green led). Then the screen goes off and the green led remains.
4) Phone can't enter flashmode/fastboot mode. It always goes to charging mode.
5) No reaction when battery is unplugged (also when any button is pressed)
Of course the battery is fully charged.
Any way to fix this?
Edit: It's a broken connector to power and volume buttons.

Phone won't turn on

I just tried to boot in to the boot loader by holding down the volume-down button while doing a reset from android (power button, tap reset) - I know it's not the right way but I was just trying it. Anyway, now my phone won't turn on. I've tried taking out the battery, putting it back in, booting to the boot loader by holding down volume-down and then holding down the power button, but I get no vibration, nothing. The screen just stays dark.
Orange light comes on when plugged in to charger. When I plug it in to my PC (Windows 7) I get a USB connect sound which is like three low notes in quick succession and then when I unplug I get the USB disconnect sound (higher note then low note).
Any ideas?
Phone is HTC Desire X in case it's not obvious by being posted in this thread.
Thanks
Try a longer press approx for 30 seconds

[Q] Unrooted/stock HTC One bricked? QHUSB_DLOAD

So my HTC ran out of battery last night, and I left it overnight to charge (red light was showing up).
So I turn it on this morning, and nothing happens. I unplug it from charger and red light is still on, and when I held down powerbutton the home and back buttons would blink, but phone would not come on.
So I read online and tried the home+vol button trick under a bright light and the red light did go away, but nothing else happened.
Now when I press power button nothing happens, not even the home/back button come up.
When I plug it in to the computer I see a driver for QHUSB_DLOAD failing to load. And if I hold down power button and volume while connected to PC, I can hear it "unplugging and replugging" noise from pc.
So is my phone bricked? This was NOT rooted, it was simply the stock device.
I really just want the pictures I have on there, is there any way to get that data back?

Powering on without button

Hello i have sony Xperia z ultra, after replacing a new housing, it won't turn on with power button( my power +,- button won't respond), it can charge and show charging view when i plug the cable, only vibrate 3times when i press the red button on sim card while chargin then back to charging view, I've tried any suggestions from internet.
Is there any jumper point from motherboard that represents power button? Thanks, or any solution
If you installed a custom recovery before (TWRP for example) you could do the following:
- Plug the power cable in and wait until the red LED turns off and the Sony logo appears.
- In this very moment begin to press the "Volume down" button several times until the LED turns to violet.
- Custom Recovery should start now. There go to "Reboot System" and your XZU should boot the Operating System as usual

A3 just wont power on

hi there, just last night i was on my MI a3 . Its battery hit the 1% mark and after flashing the "shutting down" screen it turned off.
I plugged the charger in and went to sleep. I have tried the power on button, power + volume up/volume down/ both. The white notification led blinks slowly and nothing else happens ( maybe battery is low?)
After many tries of trying to power it on and not getting to any boot animation(just a off screen) all i got was blinking leds. I tried plugging it in ,upon which the same notification led starts blinking (faster than when trying to power on), i also did not get the powered off charging animation ,screens off and blinking notification leds.
Ive switched chargers ,verified that this charger works (on another phone) and now im all out of ideas.
Thanks for any help in advance
How long do you keep holding power + volume down buttons? Try to press them for more than 30 secs.
