HTC Sensation earlier received CyanogenMod 10 (CM10) based Android 4.1 Jelly Bean update minus the performance optimisation tweaks on an unstable ROM. But the newer CM10 based ROM for Android 4.1.1 includes performance updates and superior customisation options for better overall stability.
Thanks to XDA senior member, bruce2728, the ROM brings a rich set of performance optimised features including faster and smoother interface, advanced voice recognition, Assisted Google Search, enhanced and highly customisable notifications, smarter keyboard and Google Now information cards portraying real-time updates for weather, traffic, etc. On the downside, the ROM may still contain a few bugs and broken features, as this is not an official release.
Here is the complete list of features confirmed as working and those not working:
- Front-facing camera
- WiFi hotspot - use BT tether
- Calls & data
- Hardware acceleration (videos need s/w decoder at moment)
- button lights
- Notification led
- Voice input (GNow)
- Video playback
- The ROM and the instructions provided in this guide are applicable for HTC Sensation model only and will not work with any other device. You can verify your device model number by navigating to Settings > About Phone.
- The information given in this guide is meant for reference purpose only and does not cover any warranty claims on device damage or support issues arising out of using this ROM update. Users are advised to proceed at their own risk.
- IBTimes UK advises users to backup their important personal data (bookmarks, contacts, SMS, MMS, APNs and other internet settings) to avoid data loss while installing the Android 4.1.1 Jelly Bean update.
- It is necessary to ensure that your HTC Sensation has S-Off with its bootloader unlocked. Also, make sure that ClockworkMod recovery is installed on your phone before proceeding with the ROM installation steps.
