Thank you for this post, Kudos given! I used this guide to upgrade my Lumia 800 to the new generic unbranded Windows Phone 7.8 this morning, rather than waiting God knows how long for a carrier specific update. Overjoyed by how easy it was with your instructions, thank you ;-)

Hi,

 

I've used this method to successfully flash my phone but for some reason the phone got network locked again. Has this ever happened?

 

Is there a solution?

 

Thanks
