[AT&T, Rogers HTC One X, Telstra One XL] SuPz:
The CWM on the ATT One X forum does have an issue with mounting the usb storage, so I think its best to ignore that alternative for now.

I am no Dev or programmer, but I might be able to help (a little).

First you should check if all the HTC drivers are installed. Boot your phone into CWM Recovery. Connect your phone to your laptop/computer. Then on your laptop/computer, open up "Device Manager". Have a look around if there is any devices named Android. If there is a device there, have a look at the icon. If there is a yellow exclamation mark on it, then you havn't installed the drivers correctly.

If you get to that point and have installed the drivers correctly, then retry "adb devices" in the command prompt.

If a device number does come up, then you can "adb push" your files across (I don't know the steps for pushing files...)

Last question, are you running Win8? I am and had some difficulty getting adb and fastboot commands to work properly because the driver didn't install properly through HTC Sync.

They remapped the "Recent Apps" button into a "Menu" button. This removed the 3 dot menu as it was no longer necessary. Long pressing the "Home" button will get you recent apps.

Heres my summary for what I’ve done to my HOXL today:

Root

[ROOT] One Click HTC One X (AT&T/Rogers/Others) (Win/Mac/Linux)

For those on Win8 x64 -> http://xdaforums.com/showthread.php?p=25955494&highlight=window+8#post25955494

SuperCID / Unlock Bootloader

For step 8, change from "TELST001" to "11111111"

For those on Win8 x64 and getting a "waiting for device" in cmd prompt -> When on step 11 and in "fastboot usb" mode, you will need to install the drivers again. Go to device manager and you should see a device with yellow exclamation mark called "Android 1.0". You need to manually install this driver by "Browse for driver software...", then click "let me pick from a list of device drivers...", then selecting the device shown there. (I think it was HTC device or something like that).

For those who are scared about losing warranty when using HTCdev -> It will show a “TAMPERED” label in the bootloader when you root the phone. I think that already voids your warranty. You can’t further void a warranty that’s already voided, so go crazy :D

Also wondering if anyone can get rid of the "4G" Logo next to the signal icon? I prefer the original one.

I flashed the “HTC ASIA 1.88” Radio and at least 3G works. I have yet to test 4G.

I might just try unlocking it by calling Telstra in the morning. Apparently all Telstra post-paid phones (except the iPhone) are already unlocked when sold. Can someone confirm this? I don’t have another micro sim to try it. I need to know before I go overseas next week.

I think i'm done for today. Root + SuperCID / unlock bootloader + CWM flash + New Rom (CleanROM) = Awesomely better phone than yesterday.
