[Transformer TF300T Q&A, Help & Troubleshooting] krj15489:
Hey guys,

I am having trouble installing Jelly Bean on my transformer. I have followed the apparently noob proog upgrade guide but run into issues. When I reboot after putting the upgrade files in the /cache directory the upgrade starts and goes for 30 seconds or so then fails and says that it failed to verify the package. Please have a look at my log file and let me know what I am going wrong here. Thanks.
