Question [Q] killed my phone? (SXL)

since i dont have power button(broken) i was stuck on CWM. everytime i plugged the phone i was booted to CWM menu and couldent boot to OS.
somehow i managed to reflash it to fastboot and after that it appears that its booting to OS but it was on htc logo for a while. so i thot its not going anywhere. so i unplugged it from PC. and now when im connection it to PC\wall charger. the red LED blinks once. and nothing happens.

could it be that i killed my phone by unplugging it while he was recovering ? (i used htc aio kit-->recovery option) so now theres no recovery or OS
anyhelp will be appriciated

sry for english.

thanx in advance!!
