Anyone interop unlocked a Lumia 550? I'm a bit stuck.

[Connor Price]

I've been trying to interop unlock my Lumia 550, and I've been following the XDA guide but when I get to the part where you have to use iutools to install the acersystemservice I get the error (0X80004005) every time. I'm running CMD as admin and am using the right command so I'm a bit lost.

Hi there. Have you tried the xda forum for InteropTools yet first? The developer community there are more versed to assist with errors like that and being it specific to a tool they support...

That HRESULT error though is a generic one. Have you tried a soft reset or checked to see if your phone is processing a FW or OS update already?
