Note: Run tool again to “Unregister” (lock) the phone, if you want, after all work is done. This tool is a bit buggy and tends to lose connection after registering/unregistering, so quit and restart the tool if you want to check latest status. After phone connects, select Register button.Connect phone to wifi and set correct date and time manually (weird eh?).If connecting to a phone without a SIM card:.Windows key > type “Services” > look for service and start it.Check if “Windows Phone IP over USB Transport (IpOverUsbSvc)” service is running:.
Run Windows Phone Developer Registration 8.1 (from WP SDK 8.1). Or, for developers, download the SDK with the Visual Studio installer (2013, 2015, and maybe 2012, but not 2017 and later)… but that’s a much harder route because VS is a long and fat install… and registering with Windows Dev Center (or is it MSDN? or My Visual Studio? anyhow, free registration, not $19) is required to find and download older Visual Studios if you don’t already have them. The paid account is required.)ĭownload and install Windows Phone 8.1 SDK: (I have a free dev account through Visual Studio Community edition, but this does not count. Dev accounts currently cost $19, more or less, depending on country. With a Windows Dev Center account (formerly all sorts of other names) you can unlock 3 phones at a time and manage abandoned phones through the Dev Center Dashboard. With a Microsoft account (formerly Live ID and all sorts of names) you can unlock 1 phone at a time (per account 😁). Settings > Storage Sense > phone > apps+games > Angry Birds… > tap and hold > move to SD 2. On phone, move all your Angry Birds games to an SD card (requires WP 8.1+): This is a bit laborious but possibly not as bad as what one must do to an Android 😉. Developer unlocking is a standard, Microsoft-built procedure. NOTE: You must “developer unlock” your phone to install the tools needed to gain access to the encrypted part of the SD card (D:\WPSystem) where the files of interest are stored. 
(Scroll halfway down this page for Windows 10 Mobile instructions.) Some of the precursor tools to what are used in the Windows 10 Mobile procedure may be of help if you really need to go down that road. I have no procedure for Windows Phone 8.0 and earlier. Even, revert a phone from 10 to 8.1, if possible, before beginning this operation. Thus, if at all possible, you should transfer scores from an 8.1 phone to an 8.1 phone and then upgrade the OS to Win 10. That said, the procedure for WP 8.1 requires no permanent change to your phone and should be far less risky than the procedure for Win 10 (which requires what some call jailbreaking the phone). Usual disclaimer: You follow this guide at your own risk and I accept no responsibility for damage you may do to your phone because it.
