I think I may have "killed" my HTC (Specifics in the thread)

Ok, so I'm very new to using bootloading and fast boot and all of the other developer tools, and I seemed to have killed my HTC.

I downloaded the rashr flash tool with the hope of being able to install the CyanogenMod rom to my HTC One X. Using the rashr flash app, I selected the option that allows you to flash a kernel on your phone, and I selected the img file that I downloaded which was the latest nightly img. Afterward I went into the command prompt and typed in adb reboot bootloader. From there I haven't gotten any response from my phone at all. The screen doesn't turn on, the small light indicator hasn't lit up at all, and I know the batter is close to fully charged, but there's nothing happening. Did I kill my phone? Can anyone help me out with this problem?

Not entirely sure if the phone is brand new, but my uncle bought it for me, he said it was unlocked, though I'm assuming he meant SIM unlocked because when I was able to get to the boot menu, it showed that it was still locked at the top. It had all of the packaging contents and the screen protector - so it's "like new"

The only clue I have to there still being some sort of "life" in this phone is this weird device that shows up in the device manager under "Other Devices". It says "QHSUSB_DLOAD", but no information can be pulled up about it

I hope my story is detailed enough, I can elaborate more if need be. Please go easy on me, I'm a nub but I want to learn this stuff xD.

phone killed 900$ of sd cards in 3 weeks??

so in the last 3 weeks my s4 has killed
4 128gb sandisk ultras (3 paid for as they were not covered due to being damaged by the phone 4th was replaced free)
2 64gb samsung evo's (from the samsung retail store)
2 32gb samsung evo's (again from the retail store)
a dozen+ 16gb cards from samsung/sandisk/nokia/misc cards
2 carrier provided micro sd cards (samsung evos again)

what the hell is up with the s4?

its a stock i9507(i9505) too....not even rooted.

just today it killed another evo (2 day old card!!!!!)
the phone's been to samsung 4 times too i could have bought a new s4 for the amount its cost to have them tell me there's not a single thing wrong with it.

has anyone seen anything like this with an s4?

ive also been through a dozen batteries in 3 months.

the phone is pristine there's no reason why it should be doing this.

i've had it in a lifeproof case from new till 2 weeks ago. out of the case it makes no differance and the phone runs much hotter when not charging.

while writing this. i was listening to a song via play music (all access) and suddenly i get "sd card removed" and now the card is unreadable. (pc is saying format card unknown size) (32gb samsung evo again)
