Quick Flash/Unlock Lumia 800 - Working also on Lumia 710

Here you have a little a quick guide that will give you an unlocked free Lumia 800. This guide is working also for Lumia 710, maybe on all version.

What do you need

NSS Pro 0.48 (last version Today)

The NB file you choose to flash between the custom roms you can find here in XDA ( I suggest to take This One - Unlocked and based on 12070 )

a Lumia 800, the Qualcomm One

Preparing..

First of all you need to check if your Lumia is the Qualcomm One. You can simply understand this: in installation driver, putting the phone in OSBL mode, by pressing the VOL UP for more than 8 seconds, you'll have QUALCOMM CDMA Technologies, your phone is Qualcomm. If you'll get NOKIA DLOAD, your phone is not qualcomm

Second of all, install correct qualcomm drivers, the best way is to follow the Qualcomm Drivers Tutorial, here in XDA

Third of all, check battery, you need minimum 50%
