Use fastboot to flash boot.img and it's OK .
Remember:
DO NOT FLASH THE NEW CDT.BIN !
OR YOU MAY CANNOT DOWNGRADE OR ROOT !
I flashed system and kernel. Everything running as must be but how to get root. Before flash i backup root with Ota root keeper but now can not restore, any other way?

This is a FASTBOOT not an OTA
Maybe this helps:
You can try to open the USB DEBUGGING and install an 4.0.4 kernel
Then the phone can be black screen but you can root as usual
At last flash the new kernel from fastboot
Profit!

EDIT:
Tested by chinese users : Success!

    KAIZEN ~ MotoBlur JB ROM improvement.
    - I didn't buy new phone, but new big LCD. Webtop is a must.

    0.3.2 Coming soon to GPlay. Will only upload there from now on.
    0.2.7
    - Is too old for JB. Seriously don't use it for any JB ROM.
    - There still 5000+ device still using it. (Mostly Russian, thanks to 4pda members)
    - I'm going to turn off download server soon, but many people still using it.
    0.3.0f
    - Experimental stuff. I stop over a stupid reason.
    - I don't know exactly how many devices currently using it.
    0.3.2
    - Improvement done since last month.
    - Remove GPL stuff. (No more overclock option)
    - New package name com.projectlense.bootmenu.manager
    - Direct kernel & cid flasing from recovery (restore, backup, erase)
    - MotoBlur JB ready.

    Dude, you are awesome.
    Amazing news! And BTW BMM is really popular in Russia as I told you before. Thing thing is much more poweful and convenient than that I-don't-saying-names Droid stuff.
    Keep up the good work and thank you for it!

    Russia is big.. & I just notice Vladivostok is not far away.

    0.3.2 uploaded to Google Play. Should be available in few hours.
    Hopefully it's a bug less release. Now it's time to go back & play with VZW JB leak.

    No special requirement if upgrade from 0.3.x.
    - Just install it from any system you currently boot.

    Anyone noticed after a fresh flash apps get installed from Preinstall?
    is there any problem with rm -f /preinstall ? then reinstall bootmenu?

    set sys.preinstall.done=1 in build.prop
    remove /system/preinstall

    Did anyone already deodex it?
    I'm not good at it if someone could help me I will be thankful.

    no problem on deodexing actually.
    It was my corrupted userdata partition that caused a bootloop.
    After I run e2fsck, it boot normally.
