NOTE: Bootloader should be unlocked for this method to work. Root not required.

1) Download the factory image relevant to your Galaxy Nexus from the below page.
https://developers.google.com/androi...s/images#takju
2) Unzip the .tgz file and keep it under, say C:/
3) Edit the "flash-all.bat" and remove the "-w" parameter from "fastboot -w update image-takju-jwr66v.zip"
4) Delete "userdata.img" from "image-takju-jwr66v.zip".
5) Copy fastboot.exe file into the “takju-jwr66v” directory.
6) Reboot and keep the phone in fastboot mode. [ a) Turn on USB Debugging b) Turn off your Phone c) Hold down Volume UP + Volume Down + Power buttons ]
7) Issue the command "flash-all.bat".
8) Wait for the process to finish, and then the Galaxy Nexus will reboot upgraded with stock Android 4.3
9) Cheers and enjoy !!!

So it's not just my bootloader that got slower. Yours also made you <waiting for device> each time the process rebooted the bootloader. It never happened before.

Caused a bootloop for me and when I tried to reboot in recovery I got red triangle and Android. Didn't give any error messages.
Am just going to do full wipe now and retry.

your gnex must be unlock to do this flashing process, maybe that's why you get the bootloop

My GNex hasn't even been carrier locked(they don't do that in Belgium) and my bootloader has been unlocked since I got this phone.
