Samsung Galaxy Nexus receives minor firmware update to fix GSM connectivity issues

Samsung Galaxy Nexus

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:

The prerequisites:

1. 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.
2. You need to be running stock Android 4.0.2 (ICL53F) rather than any custom ROM.
3. You need the Android SDK installed. Note the path.
4. You need fastboot. (Windows or Mac)
5. 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.)
6. Download the Android 4.0.2 to 4.0.4 update from Google here.
7. Download the latest ClockWorkmod recovery image from here.

Now, the instructions:

1. Copy the OTA package above to the /sdcard folder on your Galaxy Nexus
2. Drop the ClockworkMod file in the same folder you have fastboot in on your computer in the SDK folder (either /tools or /platform-tools).  Rename it to cwm.img to make things easy.
3. Reboot your Galaxy Nexus to bootloader mode (hold volume-up and volume-down, then press power).
4. Plug your phone into your computer, and open a command prompt or terminal.  Navigate to the folder with fastboot and the cwm.img inside it.
5. At the command line, type the following: fastboot-windows.exe boot cwm.img (or just fastboot.exe if that’s what you’ve got)
6. Use the ClockWorkMod recovery menu to flash a zip file from the SD card, and choose the OTA zip file you downloaded earlier.
7. Let things run their course.
