Thanks for your advice. I think re-locking the device means, one must be familiar with all the tools and all so i think there is no need of screenshot and also it is very simple steps.

No need to do test point method. And, yes, you can save your unlock code somewere and use it everytime you want. I used my unlock code many times, and still working, no problem

thanks for the DL link and info.
one more silly question, i have found that once the DRM keys are lost it is not possible to get back it again, so still is there any solution for it or not?

---

I really don't know, i think you can't get it back. When you requests unlock code from sony, you do it with your imei, so they have info for every phone that have unlocked bootloader and this is final. No getting back. I heard that bootloader unlocked with test point method can save your drm, but i'm not sure, better you search in general section and find more information. When i was searching to unlock my bootloader, i found out that is test point method bit aggressive and i didn't want to break my phone, so i done it with official method which is very safe.

I also have the same issue. Did you flash the nAa's JB or KK kernel before you get back to stock ICS and relock bootloader? If so, then head over to this thread
