[Nokia Lumia 800] oobritoo:
Hi guys I have been following XDA Developers for years and I love it I have found many useful tips and tricks in my time from hear over at the Android forums and now I would like to share my first post with you all not only as a thank you but also even though the nokia WP 7.8 upgrade is close I was impatient like many of you and wanted it now I read lots of threads about using navifirm+ etc and renaming files but in all honesty I think my method is easier and quicker and cuts out a lot of confusion hope somebody finds this as useful as I did.

All you will need for this Update is Nokia Care Suite.

PLEASE NOTE THIS METHOD IS FOR UPDATING YOUR ORIGINAL PHONE AND CARRIER

For Example..

Before Update your phoneis running on Vodafone WP7.5, - After Update it will be Vodafone WP7.8 (carrier locked)

Before you start get your phone code pop your sim tray out and check the code by the Barcode/QR label it should be seven digits mine is 059N8H6

Write yours down and then put the sim and tray back in the phone.

Right lets get started

We need to find a decent version of Nokia Care SuiteThis I found a little hard as a lot of the downloads are full of bloatware/spyware however this is the one I used. softpedia.com/get/Mobile-Phone-Tools/Nokia/Nokia-Care-Suite.shtml ( as a new user I cannot post the Link)

You may need to update some windows components mainly Microsoft net framework 4.0 and all that is available including the extender. you may even need to update c++ redistrubutle to be able to install Nokia care suite. however Nokia Care Suite will tell you what you need.

Download and install Nokia care Suite this will take a little while and after it is installed you then install all Drivers in C:\Program Files (x86)\Nokia\Nokia Care Suite\Drivers some will not be compatible that is normal.(my system is win7 64bit)

After all drivers have been installed you can then Open Nokia care center . you may have to go to your program files and open the Nokia Folder C:\Program Files (x86)\Nokia\Nokia Care Suite\Application Launcher\bin application launcher then right click and run as administrator.( I had Too)

once it has loaded you will have a menu double click “Product Support Tool For Store 5.0” you will see a picture of a disconnected phone and cable Click File and “open Product”

Find or type into the filter RM-801 . YOU SHOULD THEN HAVE 1 RESULT this is Our Nokia Lumia 800's click open and you will now see it on the screen (left) with the disconnected cable and phone. connect your phone so that the phone drivers get installed (after install you can leave it connected)

check that in the bottom corner their is a Globe lit up saying online it should be. then click Programming at the bottom left of the window and select Recovery. a new field will appear on screen saying Properties and you will see three boxes. Code, Variant Name and Version.

Click into the Code box and type your 7 digit code from the sim card tray you wrote down and click find online.a Box will open and lots of firmwares should appear within the popped up box in the Code section again type your code and that will give you your specific update to WP7.8

Click download and wait until it has finished after it has downloaded then click update list it should appear in the properties boxes. (if not just select tools from drop down menu and click Downloads and then double click the file)

Then Just highlight the Firmware file and click Start The software will then take over and instruct you to turn off the phone( if it is still connected) after you have done this then connect the phone to the USB cable whilst holding volume up button the phone will vibrate a couple of times and the drivers may instal again give it a few seconds and . press retry Thats it Nokia Care Suite is doing your Upgrade.

Sit Back and relax as Your Lumia 800 upgrades to WP 7.8 I am pretty sure this method will work with any Lumia device however I have only done it with MY Lumia 800 and therefore cannot guarantee it.

obviously I cannot be held responsible for any bricking or damage you cause to the your phone so only proceed if you are comfortable doing so.

Hope you all find this useful cheers oobritoo.:cowboy:
