If BL unlocked officially, warrenty is VOID, no more official updates and DRM is lost.
U lose DRM for ever if BL is unlocked by official method. TrackID app willnot work.. this is what i have in my knowledge.
I never minded in unlocking it.. since i dont use it.

If you know what you are doing, then no problem at all.. so i unlocked BL officially.(no option,, manufactured 12w14)

If unlocked by unofficial method, then u can relock it.. search in the forum to gain more knowledge..;)

I unlocked my Neo V via this method, then it turned out that something with my motherboard was wrong, so I relocked it using an ftf fie, when updated via SEUS, sent it over to SE service and got my Neo V replaced for a brand new phone for free as it was unable to be repaired, so I think all is fine when You unlock it using this method. It is just the same as the official one from website, just a few clicks less :)

Yes, indeed :) I myself, couldn't figure out the 'official' method, something was missing, but with this one it's much easier :)

I don't understand one thing!
I think this flashes a Gb kernel!
Which is why people get Sony Ericsson logo!

But how?I wanna know that!

And Gb kernels don't work with Ics Rom which people try upon! And then people get a SE logo and fear that they've bricked it!
;)
Better if you state
,to keep an Ics kernel or try it on GB fw directly !

OP Updated :)
If You want to relock Your bootloader flash an attached ftf via flashtool, then You can update via SEUS and Your phone is like a brand new, but without DRM files :)

Yes, it does flash the GB kernel which causes bootloops when flashed over ICS. Updated the OP, thanks for pointing this :)

No issues!
Good work!
Care to tell what flashes a GB kernel !? And any way to make it flash an Ics kernel instead?

Sorry Mate, but can't tell You that :( I found this program when I was looking for something that fixes 0% problem but noticed that it also unlocked the bootloader :) It's not my program, so can't make it flash any other kernel, I'm just sharing :)

Work in the phones whit:

Rooting status:
Bootloader unlock allowed: NO? is 12w20,I ask because I understand basic English, and the method for sony is saying YES.

If it says Bootloader unlock allowed=NO, then I think You can't unlock it. Still You can try, I don't think this program will do any harm to You, but still don't blame me if something goes wrong, do it on Your own responsibility :)

Somehow, the 'official' method didn't work with 12w14 or later, but with my method I managed to do so :) Maybe they do the same, but this one helped me, that's why I shared :)
Both do what they should do - unlocked the BL :)

    Hey guys,
    I wanted to share a great method to harmlessly unlock the bootloader on Neo and Neo V which works on every device (before and after 12w14). Simply follow this steps:
    EDIT: Use it over GB firmware, or flash ICS kernel after using this fix if You are on ICS and want to keep it, otherwise You will get bootloops!!!!
    1. download this program:
    http://www.2shared.com/file/xfkXTzdB/ZeroPercentFixTool.html
    2. Register Your IMEI number on this site:
    http://unlockbootloader.sonymobile.com/
    and let the code be sent to You by Sony Ericsson to your e-mail.
    3. Then open zeropercentfixtool.exe (remember to have all the drivers installed)
    4. Copy the code into the program, click fix it and connect the phoine in fastboot mode.
    5 After that it is better to desconnect the phone, and flash ICS kernel, than all should work perfectly
    Voilla, done :)
    You finally have unlocked the newer versions of xperia Neo/Neo V :)))
    PS. nevermind that the program says zero percent fix tool, it unlocks the bootloader as well. Tried on my Neo V 12w9 and 12w31 and it's working like a charm :)
    Hope You enjoy it ! :)

    I was getting the error due to absence of JDK/JRE which i have solved by installing JDK,

    Now i am in another hurdle, as per the instruction mentioned in official way of SONY

    Place the unzipped file in the usb_driver folder, located in the Android SDK > extras > google folder on your computer.

    but in the SDK there is no such folder, tried to find such folder but zero result.

    EDIT: Also the SDK manager is not working, Just showing command prompt for 1 mSec

    Make such a folder and put the file there...
