I just got Jelly Bean OTA update from ASUS for my ASUS TF300T. I had trouble getting the update, since I rooted and messed up with the system, deleted some system apps, so ASUS denied pushing the update again.
Installation
So far I fixed it thanks to xda-developers community
in this post. Unafortunetly my device was wiped out after that so I lost root priviledges.
Getting Root again
coming soon...
