I'm attempting to upgrade my Sprint FrankenPre+ to webOS 2.2.4. But I've run into an issue that I hope others have solved.

When I complete the doctoring to any version above 1.4.5 (tried both 2.1 and 2.2.4) I cannot sign into my Palm Profile.
I've gone so far as removing the device from my profile before attempting to sign in.
It only allows me to sign in after I've doctored it back to 1.4.5.

Has anyone run into this and found a way to get to 2.x?

Thank you.

P.S. I like the "Here are the similar threads we found:" that pops up to help reduce duplicate threads. Neither my search nor those suggestions matched what I'm asking.
