Default [Q] 'No OS installed! Are you sure you want to boot?' How to reinstall android os?

I dont know much about this stuff (def not tech savvy), but I decided to take my bad esn Sprint HTC One (running 4.3) and try to unlock it myself. I was successful in unlocking the bootloader, and I even rooted the device on my own (woo!!!). I was on the last stage of finally unlocking the phone, so I decided to go for it.

I tried to follow these steps to finally unlock my HTC One, but I did not know how to go to /system/app to replace the files (The 'Root Reader' app didn't show /system/app in my phone).

://forum.xda-developers.com/showthread.php?t=2491840

The files were:

HtcOMADM_SettingsPlugin_SPCS.apk
HtcOMADM_SPCS.apk

As a result, I tried to flash the copy files mentioned previously using this video as a guide

http://www.youtube.com/watch?v=JhR4Je4I8yw

I dragged and dropped the copies into the 'system storage' (not into a specific file) and started wiping data in TWRP 2.6 (Im assuming I wiped something that I shouldnt have). However, now whenever I try to boot my HTC One out of TWRP, I get the 'No OS installed..." message and it just just keeps showing the white screen with the HTC logo when I do boot anyways. When I connect my HTC One to my PC via usb cable, it doesnt even show up. I decided to take a screen shot of my files/drives/etc that I used. When I click on the 'instal' button in TWRP, it no longer shows the 'android' folder while scrolling through the list of things. My phone also automatically shuts off when leaving it on idle (TWRP running) for a bit, it doesnt connect to my PC anymore too

What should I do to get the phone working again? Could I unlock it from here or do I have to backtrack or something? I have very little knowledge about this stuff so please try to explain things easily for me lol

You need to relock your phone and run a ruu and to reroot your phone with the latest version of twrp 2.6 .3.0 and supersu 1.9.1 I think but you can check that when you run the ruu in the app store real quick to see if it is the latest version.

On the PC download the RUU

http://dl3.htc.com/application/RUU_M...3_signed_2.exe


Connect USB cable to the phone to the PC (keep the phone connected until you are done)

1. Boot your phone to the bootloader (volume down and power on). Go to fastboot option on the phone menu.

2. Now using fastboot on your PC type fastboot oem lock

3. Boot your phone to the bootloader (volume down and power on). Go to fastboot option on the phone menu.

4. Now using fastboot on your PC type fastboot oem rebootRUU

5. Run the RUU that you downloaded. That will put your phone back to stock.

---------------------------------------

To unlock the bootloader:

1. Goto http://www.htcdev.com/ follow the steps.

Install custom recovery

2. Install TWRP. Download http://techerrata.com/file/twrp2/m7w....3.0-m7wls.img put in in the same folder on your PC as your fastboot.exe command.

3. fastboot flash recovery openrecovery-twrp-2.6.3.0-m7wls.img

4. reboot phone.

Install root:

download http://download.chainfire.eu/351/Sup...etrieve_file=1

copy UPDATE-SuperSU-v1.65.zip to the phone

Boot your phone to the bootloader (volume down and power on). Go to recovery option on the phone menu. That will boot into TWRP. Use the install and install the zip UPDATE-SuperSU-v1.65.zip.
