[Samsung Galaxy Nexus] afextwin:
Does anyone have any info on getting the phone's internal programming back to stock after all this tinkering?

I'd like to use the phone with verizon but I can't connect to the mobile network.

I reflashed using Odin 1.8.3, the stock 4.0.2 pda/phone using EFS clear option. [my imei is still on the phone]

No signal, so I used fastboot to flash the stock 4.2.2 images. Again, no signal.

So here is the script I used, I think it might not have been compatible with the version of ETSI I was using..
