Device won't boot anymore for unknown reasons.

pladi1

The device felt out of my hand and since then the issue started.
Device is fully updated. Have "disallowing usb" option enabled under Settings > Security.

The issue is:
When connecting the device to my computer it reboots automatically.
After Google logo the device reboot again. I am unable to enter the fastboot.

As far I know the latest update has been installed on the device as I check this regular.
Anyone can help me with this issue to fix the device without losing any data?

pladi1 If the device was damaged and won't pass the bootloader/Google screen, then your devices motherboard was most likely damaged

Contact Google repair, we can't recover any data unless you are able to boot into GOS

Maybe if you're lucky the problem is just a loose cable. But that sort of determination may best be done by a repair shop.

Cable disconnected > hold 30+ sec power button > no feedback.
Cable disconnected > power + volume down btn > no feedback.

Hello, the devices is not damaged from the outside. It felt from 10/20 cm on the ground only. But the hardware from outside looks fine.
Sometimes the display is flashing. Could this be the issue?

pladi1 "Sometimes the display is flashing"

Your phone is damaged if the screen is randomly flashing white, only Google repair services (or your local repair store, but I like Googles repair service personally) can help you atm

When I connect the cable and press power + volume button I feel a little feedback, but no display. And the device reboots automatically again. After the Google logo its repeating in booting.

@pladi1 I agree with raccoondad. It sounds like something was damaged, even if the damage doesn't look very serious from the exterior.

If it's a display issues, the OS won't boot?

There are many parts of the system that will refuse to work if they detect "impossible" situations, including hardware providing nonsensical responses.

If a phone suddenly starts behaving erratically right after a drop, it is very likely that the next productive step is to take the phone to somebody with hardware-repair experience.

pladi1 We don't know what the issue is, but if you dropped it and the display is failing, then it could be anything. We can't diagnose the problem with the device because its almost certainly a hardware issue that requires physical repair. Contact google repair support

It may of not even be caused by the drop itself, we don't know, and we can't help you. If it doesn't boot into GOS or enter fastboot we can't do anything because its a failing device hardware/bootloader wise and we can't really touch on that. That's 100% a Google territory
