Step 5: Flash the firmware!
Now you have booted your phone, stay on homescreen and use the following command in CMD.exe:
adb reboot oem-78
Now your phone is rebooting and a black screen with silver HTC logo appears.
Remember you have firmware.zip copied to your C:\ drive!!!
Use the following command now:
fastboot flash zip C:\firmware.zip
The first time you will see that this command will fail, just repeat the command and this time it will succeed!
Now you see in CMD.exe that the firmware.zip is successfully pushed! The black HTC screen stays with a full green bar under it.
Now use the command:
adb reboot-bootloader
Stay in the bootloader for now.
Step 6: Download HTC One X All In One Toolkit

Step 7: Unlock your device again!
Now you are in the HBOOT mode, you can unlock your device again. I have used the tool you just downloaded.
If you have unlocked your device before you still have your unlock.bin in your inbox from HTCDev.com. Download this again and put it in the folder 'data' in the folder of the All In One Toolkit.
Stay in fastboot with your phone connected to the PC or laptop and open the All In One Toolkit. Choose '5. Unlock Bootloader'.
Now you get a black screen with 2 options: Lock Device and Unlock Device. Choose with your volume button 'Unlock Device' and confirm with the power button. Now you are unlocked again!
Step 8: Flash Recovery
Now you are unlocked again, stay in fastboot mode and use the All In One Tool.
Choose: CWM 5.8.4.0. Now you have installed successfully CWM recovery.
Step 9: Flash boot.img and install the ROM
Flash the boot.img of the JellyBean Sense ROM. When done, go in recovery and flash the ROM.zip.
NOW YOU ARE DONE, AND CAN SUCCESSFULLY BOOT YOUR NEW ROM! A FRESH HTC ONE X EXPERIENCE
