How I bricked and unbricked my Xperia S after flashing kernel

I was testing my Xperia S with images from CyanogenMOD and OpenSEMC projects, then after flashing this kernel:

# fastboot flash boot OpenSEMC-kk-beta2-oldmapping-boot.img 
sending 'boot' (9223 KB)...
(bootloader) USB download speed was 36326kB/s
OKAY [  0.275s]
writing 'boot'...
(bootloader) Flash of partition 'boot' requested
(bootloader) S1 partID 0x00000003, block 0x00002000-0x0000bfff
(bootloader) Erase operation complete, 0 bad blocks encountered
(bootloader) Flashing...
(bootloader) Flash operation complete
OKAY [  1.727s]
finished. total time: 2.002s

And this combination of files:
OpenSEMC-kk-beta2.zip
pa_gapps-stock-4.4.2-20131230-signed.zip

My device didn’t started anymore, all I see was a black screen.

I was following the instructions from this page:
http://www.androidhogger.com/how-to-install-cyanogenmod-11-android-4-4-xperia-s.html

Then after searching how to unbrick a Xperia S I found this thread:
http://forum.xda-developers.com/showthread.php?t=2088525

Then tested the hard-reset: VOLUME_DOWN + VOLUME_UP + POWER. I feel the vibration of phone starting but after plugin the USB cable nothing is recognized. Trying this hard-reset with USB cable plugged didn’t work. I removed the cable from computer and as fast as I could pluged it back after hard-reset and saw this using $ dmesg command:

[ 3974.182383] usb 3-1: new high-speed USB device number 15 using xhci_hcd

[ 3981.484941] usb 3-1: Manufacturer: Qualcomm CDMA Technologies MSM
[ 3984.927213] usb 3-1: USB disconnect, device number 17

Then I decide to test another approach: hard-reset and execute fastboot command to flash a known kernel:

# fastboot flash boot S_DooMLoRD_AdvStkKernel_FW-96_v3.elf 

sending 'boot' (9244 KB)...
(bootloader) USB download speed was 36408kB/s
OKAY [  0.275s]
writing 'boot'...
(bootloader) Flash of partition 'boot' requested
(bootloader) S1 partID 0x00000003, block 0x00002000-0x0000bfff
(bootloader) Erase operation complete, 0 bad blocks encountered
(bootloader) Flashing...
(bootloader) Flash operation complete
OKAY [  2.291s]
finished. total time: 2.567s

Great it worked and I can use ClockWorkMod again to flash a good Android version.

We follow and write posts exactly according to the instructions provided by the developer of the rom itself following its XDA thread or known location. Still whatever happened i sincerely apologize for that. I am happy that you were able to fix it back.
