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:
2. Register Your IMEI number on this site:
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
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 !
