After successfully installing 3.3u1 (a couple of times), I went to re-install again today. Wiped everything. Flashed the install file from recovery, all goes well until the "finalizing the installation" "writing boot image" bit. Then it hangs, requiring a battery pull.
I downgraded to 2u2, which installed fine. Then I re-downloaded 3u1 and flashed it, with exactly the same result (this was going through the full installation as the "upgrade" bit wasn't available).
So I now have a fully functional 2u2, that won't upgrade to 3u1.
