I can't download MRE SDK, but why? Which SDK is correct for Nokia 220 MT6250?
You shouldn't encounter any problems with the download of mre.sdk. Maybe you don't get it from a reliable source. You can search through the versions available from mediatek by accessing the following link: http://mre.mediatek.com/en/sdk/2.0
It is recommended to install MRE SDK' latest version.
