[AT&T, Rogers HTC One X, Telstra One XL] taylor.fowler:
These are flashable zips that will change your baseband (radio firmware). Google it See twistedxx's post quoted below if you have no idea what this means. If you have an HTC One X (Tegra 3) you're in the wrong place.

If you're on the newer HBOOT (1.14) and insist on running a Sense based ROM use the Jet tool to downgrade to 1.09. This will allow you to write to the radio partition of the phone. Or just S-OFF (w00t!)

If you're running a CM 10.x ROM it doesn't matter what HBOOT you're on as the radio firmware is stored elsewhere (in a writable partition... /system to be precise).

Instructions:

1) Copy zip file to SD Card

2) Boot into Recovery (CWM or TWRP)

3) Flash

4) Reboot

Always take a Nandroid Backup in case something goes screwy!

Your bootloader will not show the correct baseband. I'm working on figuring out how the RUU updater handles the android_info.txt in the firmware.zip's

These are radios for flashing in Sense OR CM 10.x builds after 7/15 nightly!!!. They don't include the RIL files.

CURRENTLY THE DROPBOX LINKS ARE DEAD, THEY'LL BE BACK SOON (Migrating everything over to dev host to avoid this situation in the future)
