Apologies, I was busier than I'd thought I'd be.
This should get you up and running with a custom ROM, we'll choose a standard Sense based one for now, then you can start messing about with alternatives later, the important thing is to get you back in action.
1. Head Here:
Techerrata Downloads - Browsing endeavoru
2. You'll need an older version which will allow you to mount as USB storage in recovery, look at 2.3.x or 2.4.x (2.4 might be best)
3. Place it in the folder you have all the other HTC stuff (the unlock token, fastboot.exe etc).
4. Rename the img file to recovery.img (don't type recovery.img, just type recovery and it will add the extension itself).
5. Boot your phone to the bootloader, select Fastboot, connect the phone to your PC.
6. Open a command prompt, navigate to the folder you have the recovery.img file and type
Code:
fastboot flash recovery recovery.img
7. Reboot the phone back in to the bootloader, using the volume keys, select recovery and with any luck, you should load in to TWRP?
8. Head here:

9. Download a file called Android Revolution HD 21.0 (Jelly Bean)
10. Place the file on your desktop, and open (don't extract) the zip file and look for a file called boot.img
11. Close the zip and copy boot.img to the folder with the fastboot files in it.
12. Head back to your phone, head to the mounts and storage menu, then select mount USB Storage. Hopefully your phone should eventually appear as a USB drive on your PC. (if it doesn't things could get complicated
) When/if it does, copy the ROM zip file to the root of your storage.
13. Once done, unmount the phone in TWRP
14. Head to the backup section and take a backup
15. Reboot back to your bootloader, head to fastboot open a command prompt and navigate to the fastboot folder again and flash the boot image using the command:
Code:
fastboot flash boot boot.img
Then
16. Go back to recovery, select wipe, then factory reset and wipe the cache and dalvik cache too.
17 Back to the main menu in TWRP, select Install, Install Zip from SD Card and then select the ARHD.zip you downloaded in step 8.
18. The install process should start, just select all the default options in Aroma, ensuring you do a full wipe if it asks.
19. Let it do it's thing and when it asks you to reboot, do it.
20. Let it boot and hopefully, it should take you in to your new ROM (bear in mind 1st boot could take up to 10 minutes).
If that doesn't work, let me know, I'll have to ask someone else to chime in. A lot of that is done from memory, I gave my One X to the Mrs and she's not been about for me to let me have a play.
