But some who had used an unauthorized tool last month to get the NoDo update said that they were unable to install Tuesday's patch.
After developer Chris Walsh released the tool in early April -- and before Microsoft asked him to pull it -- Hautala had claimed that users might not receive future updates, or could experience other problems if they used Walsh's software.
Walsh had stepped in when Microsoft was unable to promptly deliver a pair of promised feature-related, non-security updates for Windows Phone 7. By late March, users were ranting online about the slow progress of those updates, which eventually prompted a mela culpa from Microsoft's chief smartphone executive.
On Tuesday, Walsh reported that he had successfully retrieved and installed the security update on three different phones that he had earlier "walshed" -- the nickname others have given to the process of grabbing early updates using his tool -- but was asking others to share their experiences. Several responded, saying that they had received error code 81080005 after the updated failed to install.
To install the security update, users must connect their smartphone to a PC or Mac.
