AT&T may have refused to provide bootloader unlocking for their One X, but that hasn’t stopped custom development on the device from happening. In the latest development, an unofficial Android 4.1 based CM10 ROM has been released for the AT&T One X by XDA Recognized Developer h8rift, giving users of the device a chance to try out Jelly Bean with all its features.
NOTE: The ROM is a very early alpha build and hence is not to be considered suitable for everyday use, as it has a long list of issues and things that don’t work. Also, CM10 is in its early stages, so don’t expect most of the customization features of CyanogenMod to be present in the ROM at this point.
The list of things working/not working quoted from the developer (the most updated list can be obtained from the development page linked in the guide):
- Voice / Data
- NFC / Android Beam
- App Switch button = Menu
- Proximity sensor
- Video is kinda wonky. See YouTube for example.
- Multi-touch (need kernel source)
- Camera (not working at all)
- Video Camera (not working at all)
- Wifi Hotspot
- USB Tethering
- Notification LED
- Google Wallet (May not ever work. Very very low priority)
- Wired Headset (and maybe Bluetooth Headset) does not work yet.
