Is it still possible to Developer unlock a Windows 8.1 phone? I have some audio recordings which are on the SD card inside the WPSystem\AppData and the app which recorded the audio crashes right at launch, rendering the data useless; however, EaseUS data recovery easily allows view of the audio files, but when I recover, the data is straight copied without decryption making the recovered file useless.
I found the answer here: Windows Phone WPSystem folders "security ID structure is invalid"
,but the phone needs to be developer unlocked and I cannot find a way to do it, all the google research turns up developer unlock solutions which are no longer available for download.
Any assistance would be appreciated.
