ASUS (2357) has finally made good on its promise to update its Transformer Prime tablet to Android 4.1 Jelly Bean. The only downside, however, is that Jelly Bean needs to be side-loaded into the Transformer Prime. To update the Transformer Prime to Jelly Bean, users can visit ASUS’s download website and search for “TF201″ and select “Eee Pad Transformer Prime TF201.” On the “Download” tab, change the OS in the drop-down menu to “Android.” Select “Firmware”and download “Version V10.1.2.15″ to get Jelly Bean rolling. Jelly Bean is also rolling out to ASUS Transformer Pad Infinity tablets as well. To update, search for “TF700T” instead of “TF201.” Both ASUS tablets should run significantly faster thanks to Jelly Bean’s “Project Butter” speed enhancements.
