With yesterday's release of Android 4.0.2 for the Samsung Galaxy Nexus, it looks like the never ending story of the faulty German ROM comes to a happy end, if the devices in question are going to receive the update. But at this point, it's not clear if they will receive it over the air - or not. GN Official Update Checker is a small tool which verifies if Google will push updates to the devices in question or if others, like carriers or Samsung itself, have to take care. To recap: When Samsung Germany released the first batch of Samsung Galaxy Nexus they flashed it with a volume bug fixed ROM. Unfortunately, Samsung used a differently signed ROM which prevents to update Google apps.
As a matter of fact, Samsung released the original Galaxy Nexus firmware after which needs to be flashed by the end-user. If flashed, the Galaxy Nexus is finally running the official Google Ice Cream Sandwich version and everything is good. If not flashed, Google isn't taking care for FOTA ROM updates because the device identifies itself with a different firmware version which is seen as a kind of Samsung firmware.
This means, Google isn't pushing out any ROM updates, like yesterday's Android 4.0.2 update and it's not yet clear if Samsung will update these devices over the air, or not.
The best advice is to flash faulty devices to the official Google Galaxy Nexus ROM but since Google has already released the Android 4.0.2 ROM package for the Galaxy Nexus, users can go straight to the latest firmware version instead of flashing Android 4.0.1 first and receiving the 4.0.2 update later.
GN Official Update Checker is now available free of charge from the Android Market and lets users know if their device will receive the update from Google or not.
