A few reports this morning show that the GSM variant of the Samsung Galaxy Nexus is receiving a minor firmware update. The OS build will go up to version IMM761, from the older IMM76D. The update reportedly fixes minor bugs like GSM connectivity issues and a screen lock lag when automatic brightness was engaged.
We should see the update go live in more markets during the next few weeks, so keep on checking your device’s OTA notifications to know when it’s ready for your device.
If you can’t wait for this update to hit your device, then you can try out an optional method described below:
You need a GSM Galaxy Nexus with the product codename ‘yakju’. NOT the Verizon Galaxy Nexus, or ‘yakjuxw’, or ‘yakjusc’ or any of the other variants we’ve heard about. Check your product name before you begin using this app.
You need to be running stock Android 4.0.2 (ICL53F) rather than any custom ROM.
You need to unlock your bootloader. If you haven’t done that (and you really should), here’s how. (Note that if you haven’t already completed this step, unlocking your bootloader will wipe all data on your phone.)
