Hello everyone, I had the luck of get a sealed Nokia n950



I'm reading this website for long time, but I just get a lot of topics, guides, links, wiki entries with a lot of content. So I don't know from where start. I will put a list of things that I've found and doubts that I have about.

1- I'm interested about the possibility of re-flash if I install something like nitroid or other OS and want back to the original OS.

My phone OS version is: meego 1.2 Harmattan 1.2011.15-7_PR_RM680 , but I can't find any mirror or guide to re-flash a n950.

2- Guides and topics about how update the device that I found::

[HOWTO] Comprehensive Firmware Flashing Guide for N9 :

-This guide seems outdated, and he do not explain the reason or advantages of flashing the device.Most of links are broken.
