How hard unlocking a smart phone DIY ?

I never tried unlock a phone, but now I am interested in it, I am looking for a spare time to unlock Nokia Lumia 710, actually in most of cases, Nokia Lumia 710 and 800 seems the same kind of phone but just some hardware different, especially for firmware development, 710 and 800 always have been looked the same kind of phone but just firmware versions different, but, for unlocking, 710 and 800 most like using same guide.

OK, I am not going to start the unlock right now, so today I just do some preparations, I collect some helpful information, if you can not wait, you can start now but please know I have not tried all steps myself. I DO NOT know what will happen and whether they work for your phone, please make sure you can do by yourself before you start.

(picture from internet) The first help link is using NSS software, which is from xda developer website: NSS 0.50 - Sim Unlock for rooted Lumia But, But.. please read carefully what the forum were discussed, the 5 steps just brief info, actually before you start, you have to finish some other steps first, which they will spend you a NOT short time, at least if you are new for unlocking phone, you have to understand what the software you have to have, and how to use those software tools, and, what they do for… etc. So, as my understanding by now, I have to unlock the boot loader for my Lumia phone first, otherwise the NSS tool I mentioned above can not recognize your phone in a right mode. and then, we need Nokia care suite software to do the next steps…. How to unlock boot loader ? check this tutorial: Jailbreak/Unlock/Debrand Nokia Lumia 710 - Downgrade to Qualcomm The Nokia Care Suite tool download from here: https://docs.google.com/uc?id=0B3qYFBKKL2hiM21waFhoNHFTb2c&export=download Nokia Care Suite Tutorial: http://www.youtube.com/watch?v=k1e3xAZCzZY   OK, above I just collect some information, I said I am not going to start the unlock today, I will do in other day if I get time. Please find your information if you think you need more, and please note you take all risks by yourself. Good luck! See you next time if I start the unlocking… :)
