[Q] Device wont turn on after loosing all the battery topic

Hello. I am facing a serious problem. The device accidentaly lost all its battery when it was turned on and it turned off. I tried to charge it while it was off but it seems that it is not charging because of the unlocked bootloader (i unlocked it with freege. i think that the bootloader is mako geehrc). The result is that when I press the power button it shows the boot animated logo but then suddenly it shows the shut down animation logo and it turns off. :crying:

Also it turns on only when the charger is connected. Otherways, the power button does nothing. What I am going to do?
