Exclamation [Q] [URGENT] Hanged on Bootloader what to do

Hi,

I just became stupid again. I got my phone hanged upped on BOOTLOADER. after trying "fastboot oem writecid HTC__044"

i got this message.

(bootloader) elite_init_sd, SD card already power on
(bootloader) sdhw_7xxx_open: id=0
(bootloader) [SD_HW_ERR] SD: No device attached
(bootloader) 902910 902E20
FAILED (status read failed (No such file or directory))
finished. total time: 1.273s

I noticed its hanging now, I did this with unlocked bootloader

how do i know if this is still workable? how can I get out of the bootloader. I promise not to do anything stupid If i get passed after this
