Everything works fine here
But that's old news now, no need to bug with flashing zip's


ROOT for LOCKED bootloaders
1)Flash(if you didn't already) 4.0.4(4.1.B.0.431) ICS and boot phone (links are in post#1)
1.1) turn usb debugging on
1.2) allow unknown sources
1.3) select MSC mode (settings->Xperia->connectivity->USB connection mode->MSC mode)
2)Flash kernel from 4.0.3(4.1.A.0.562) ICS and boot phone. Flash only kernel, don't wipe anything!
Note: in settings->about phone: nothing will change, nor kernel version, nor the build number (That is OK)
3)download DooMLoRD's Rooting Toolkit for Xperia 2011 ICS [FW:.562]: http://xdaforums.com/showthread.php?t=1601038
read instructions and root your phone
(in case you are on linux, thanks to cha0sxl go here: http://xdaforums.com/showpost.php?p=26927754&postcount=114)
4)flash back kernel from 4.0.4(4.1.B.0.431) ICS. Flash only kernel, don't wipe anything!

p.s. yes, this works for both, Neo and Neo V.
For Neo users, in step 2, you use kernel from Neo V of course. And, Neo users, don't worry about errors when booting with .562 kernel.
If you don't see your contacts after importing them, go to menu->filter-> and play with settings here.

End of story.
Enjoy in your rooted phone with locked bootloader.

In case someone is afraid that his finger will slip and that he will wipe something while flashing only kernel, I uploaded ftf's with only kernel.

ROOT .587 for LOCKED bootloaders

It's same as with .431, but as I can imagine some people would be confused if I add instructions to old post, I (mostly) copy/paste my old post.
Please don't ask when this or that fw will be released. If you see it it's here, if you find it, post it. I still need to check some of the ftf's floating around, as region is unknown.
