    Default Issue: Upgrade to factory image 4.1.2 with Root Toolkit

    I would like to move to factory image (JZO54K) for my Samsung Galaxy Nexus S phone (i9020a) and to factory settings.

    Currently I am on 4.1.1 Build JRO03C. When I try to upgrade via Root Toolkit I get the following message on the screen <see image>.

    Any recommendations?

    Do you have a GSM Nexus or a Nexus S? You posted in the Nexus forum. You might get more help in the Nexus S forum. You also should add more info like what carrier etc. Good luck!

    your phone is Nexus S and there is other phone called Galaxy Nexus. you mixed up both names.

    ok, to answer your actual question. have you downloaded the right image

    or follow this guide How-To Unlock Bootloader/Factory Restore/Root any NEXUS device

    The Nexus S forum does not seem to exist @androidcentral, or am I missing something?

    Thank! Actually I am more comfortable using the Root Toolkit. They suppose to pick the right upgrade for you. I'll try the manual upgrade (with Root Toolkit).
