Nexus S Android 2.3.4 Variants, Update For Various Models

Many Nexus S users in India and many other countries are facing problems updating their Nexus S to the latest Android version 2.3.4, some of them have got the OTA but it does not really update the device. The manual update also depends on the model of various Nexus S in different countries. Many people have been telling me about this on twitter and asking me for a workaround so I thought of writing this post so that all the people having difficulty updating the Nexus S can download the manual update according to their model Nos.


Let me first say that Google has been rolling out the updates according to the model no, the Super AMOLED devices in the US are getting the OTA updates first, whiles the SLCD versions in India and other countries are coming in a bit late. So this guide will show you the Model Numbers and the specific ROM for that model.
