Dear friend
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%


How TO

  • Open NSS PRO
  • Go To Flashing - WP 7 Tools
  • Power on Phone normally
  • Let Windows Find your phone with correct drivers
  • On Bottom - Left choose Nokia Connectivity
  • Click On DETECT
  • Where Software say "Normal Mode", click on OSBL Mode e give a click on the arrow
  • Now click on "OS File" and choose the NB file you want to flash
  • Click on Write OS
  • All Done - Good Work Boss

Nice guide, you should add a line for people with DLOAD bootloaders on how to flash the QC one

Also this line

Perhaps it is a good idea to include some links to more 'how to's' in the openings post, e.g. I can't find how to go to the installation drivers. Yep, I'm new to WP;)

Here you have a little installer to Force installation of correct drivers for Nokia Lumia Qualcomm Based.

The software will include in OEM driver, the ones for our beatiful phone :)
Here we go...

  • Download The package Qualcomm Driver Installer For Nokia Lumia
  • Unrar it on your desktop
  • Click on the qcusbtest.cer and install it, choosing Root Authorization, and Trusted Authors ( don't know if is the correct translation, because my OS is in italian :) )
  • Then Run the driver Installer with Administrator Right ( right click on the software, Run as Administrator )
  • All Done :D

As usual, yu will have to make it clear... simply pressing Vol+ for more than 8 secs does nothing... (even after 60 secs)
Once for good, make sure about how doing it really... and correct it in your post...

Might be nice if you could actually include how you downgrade to Qualcomm bootloader on the Lumia 710.

I've followed the instructions on the other post on how to downgrade the bootloader but for some reason it doesn't seem to work.
