I believe Google have plugged the hole as I can't download any of the packages that would be otherwise restricted for my device/country. I keep getting App not found error like many others on this thread. Either that or we need more information on filling in the Device fields. I have an international i9505 and have no idea where to get the SDK version, Device Name and SDK Version from.
Already purchased items or unrestricted apps download just fine, but that is not what I needed this to do for me.
Just for reference I was trying to download: com.sec.watchon.phone.plus which is made for the i9505 but apparently not available in my country.
Lurking xda since the HTC Typhoon era.
