HTC has clarified their decision on why Desire HD would not get an official update to Android Ice Cream Sandwich.

The company said that the update would require them to repartition the storage space on the device because of the disk requirement of Ice Cream Sandwich.

This means that the users would lose their data during the upgrade process.

The company said:

For more background, due to how storage on the HTC Desire HD is partitioned – and the larger size of Android 4.0 – it would require re-partitioning device storage and overwriting user data in order to install this update. While technically advanced users might find this solution acceptable, the majority of customers would not. We also considered ways to reduce the overall size of the software package, but this would impact features and functionality that customers are currently using. Even after installing the update, there were other technical limitations which we felt negatively impacted the user experience.
