Hard brick huawei ascend Y300

[honey29695]

I was in team win recovery with my y300....
25% battery was there...running custom CM 10 Rom was working fine for me...
Was in TWR to backup my data but decided not to do so as i had some urgent work...
so I went simply to reboot in TWR to reboot my system...
there were four options to reboot...
1.system
2.turn off
3.bootloader
4.data or something else...
I instead of pressing 2 one pressed bootloader....
my phone turned off I tried to power it on but no response from power button...
so my phone is dead now is there any way to power it on...???
Rebooting bootloader caused it...???
Is it software or hardware problem...???
PLzzzz Help...

I was just in the final stages of the upgrade to the officail ICS and my phone decided to started the following cycle , i turn the phone on and after 2 seconds it has the huawei splash log which lasts about 1 second and then it turns off for 1 second and then repeats continually.
