when i woke up this morning, my phone is dead and it won't come back on.
Please help me, guys!!!

is the battery fully discharged?

The battery is probably totalled.

The only way to wake it back up is to either (1) find someone with a battery with power in it, and figure out if you're only partially flashed, or (2) you can TRY the AC mains charger. It MAY be able to charge it.

The USB charger will not work unless the phone's firmware is intact, as the phone has to manage the charging request (for power) from the USB cable and without the logic functioning it won't ever ask for +5V to be sent down. USB negotiates power requirements.

The AC charger is just a dumb charger and MAY be able to do the job. If not, find someone else with an MDA and swap batteries with them - they will be able to "Wake" your dead battery with the AC charger in their phone, and you can then use the power to figure out what's up.

thanks, guys it came back on
but it stucked with bootloader screen, what should i do, now?

It has no firmware in it (or the load was interrupted)

Flash a valid firmware file. It will flash from the tri-color bootloader screen.
