Searching for factory image of NTT DOCOMO GALAXY Nexus? i am in search of factory image for my new NTT DOCOMO GALAXY Nexus from japan ... i have checked on https://developers.google.com/android/nexus/images but could not found for Android 4.0.4 (IMM76K) GSM/HSPA+

actually i wanted to root my device using nexus root toolkit application and that application has detected my device as GSM/HSPA+ , But on the https://developers.google.com/android/nexus/images link there is Factory Images "mysid" for Galaxy Nexus "toro" (VZW CDMA/LTE) Android 4.0.4 (IMM76K)

I am not sure CDMA/LTE image can be used, if anything will go wrong while rooting so i can use image to flash device.

please help/suggest me!!
Hardware-wise, the NTT DoCoMo (SC-04D) and the version sold on Google Play Store (GT-i9250) are identical.  You should be able to use one of the "maguro" takju factory images (ICS or JB.)  Definitely do NOT use the CDMA/LTE image.
