[NOTE]NOTE : If you have a lot of games saved then you might be reluctant to follow this procedure.[/NOTE]
I did the following set of steps to upgrade my Nokia Lumia 1320 from WP8 to WP8.1 Dev Preview. Its been 2 days now and haven't faced any issues as such.
(STEP 1) Do a hard reset and get the phone back to factory settings i.e with GDR3 (Nokia Black) with your latest firmware.
[INFO]1) Turn off your phone.
2) Turn on your phone again by pressing the volume down button until you see the exclamation mark !
3) Then, reset the phone by pressing the following four buttons in this order: Volume up, Volume down, Power, Volume down.
4) Your phone should now reset and restart itself. (It might take a while for the process to complete.)[/INFO]
(STEP 2) Register on app studio, download the Preview for developer app and install it. It can be found here :
Preview for Developers | Windows Phone Apps+Games Store (United States)
(STEP 3) Check phone for updates by going to App List --> Settings --> Phone Update --> Check for update and install WP8.1 Dev Preview
(STEP 4) Once the install has completed, do a hard reset following the method mentioned in (STEP 1).
(STEP 5) Then install your apps one by one onto the phone or SD card. To install them onto the SD card go to App List --> Data Sense and select SD card option for apps.
(STEP 7) Once you have finished installing all the app, then do a soft rest. (Press Volume Down button + power button for few seconds till phone reboots)
And then your good to go. This is the cleanest method for a upgrade in my honest opinion. Keeping my fingers crossed that in the days to come nothing goes wrong and everything continues to run smooth. :smile:
