A bit weird though: I tried to relock using oem lock, and after that it failed to boot stating "Failed to boot LNX 0x0004". Apparently, this happens when the installed software is not 100% stock. Sorted it out by unlocking again, but a word of warning to everyone doing this.
I was on 100% stock 4.0.4 IMM76 before doing this. No custom recovery or root or anything.
Alright I did get this to work with the latest EOS Xoom recovery... can't post link still but in Xoom Dev it's this thread: [Recovery] EOS recovery (R6) CWM Based
After flash EOS recovery, install from sdcard/update.zip like normal and this version of CWM appears to actually bypass the asserts and does the update. I have no desire to lock bootloader again so that error didn't bother me.
This update brings the Xoom up to 4.1.1 as seen in the screenshots. Please update the main thread with link and EOS recovery.
Haven't had much time to use it but I can confirm Google Now is much better the S Voice on my GSIII which we already knew. Most things seem about the same speed wise with home screen switching actually seeming a little slower than before. Having Google Now on Lock screen is nice, fonts are OK, transitions starting apps seem smoother.
