Motorola issued an upgrade for the Motorola ATRIX 4G this week. It’s not much of an upgrade (we know they’ll be looking to get this thing stepped up to Gingerbread, but this isn’t it) but if you wanted it and can’t wait for the OTA process to ping your phone then you’re in luck – the guys at BriefMobile have found the SBF file that you can use to get stepped up to the latest version (4.1.57). They’ve posted instructions over on their site so be sure to check those out.
In related news, that same OTA upgrade cannot be rooted as it is, unfortunately. XDA is always there to rescue us, though, as they note that you can keep root if you were coming from a rooted version of the previous build (4.1.26). Make sure you’re rooted before you accept any OTA or OTW upgrade and proceed to follow the instructions here. [via Droid Matters]
