[Transformer TF300T Q&A, Help & Troubleshooting] Hayde:
Sigh... since I dont have 10 posts here I'll put it here.

Im from Europe, had probably a WW firmware, downgraded to US.17 and rooted.

Like all the others, I cant get US firmware to install OTA.

So here are the logcats, I wonder if anyone can help.

Methods of work:

Logcat of normal updating (that obv is failing)

I get this message from logcat:

Since it was an all American party of who CAN receive the OTA. I setup a vpn and tried it through an american host. This host was located in San Jose.

So after a reboot and the setup vpn server.

I get this logcat:

So after looking, I found a logcat on this site here from a tf101:

http://xdaforums.com/showpost.php?p=15695180&postcount=23

Can anyone see what the problem is? And why EU can't get OTA from the rooted US firmware?
