    Haha, that was quite stupid of me; I used the wrong userdata file. Through which of the steps do I have to go to fix this? Entering only the userdata line doesn't work.

    The hiccups I experienced were merely to blame on my own inexperience.
    - Installing packages via the Google SDK program didn't work at first, but I finally solved that problem by ensuring the folder WASN'T Read-Only (which my computer seems to do automatically), and that I had full rights of manipulating the folders and files within.
    - Only after a while did I become aware of the fact that it is only possible to use the Command Prompt WITHIN the \platform-tools folder, and not in any other location, so everything must be moved there first before using the Command Prompts.

    don't worry u can't even imagine the stupid things that I did to learn all this, I guess it's a part of the learning curve.Regarding your query I think you have to install the firmware and OS again using the 64G, now that u have done it once I don't think that should be a problem

    Thanks a lot - everything works correctly now. I have a tip for some beginners wanting to execute this as well: make sure to extract the Bacon Signed Fastboot zip-file DIRECTLY into the platform-tools folder, so that all the files are dropped in there, and NOT in a bacon-signed-fastboot folder WITHIN the platform-tools folder.

    I'm running into an issue on step one. I'm able to install/update the driver software for adb interface and composite adb interface, but I keep getting an error for the bootloader interface (error 10)

    I suggest you to try with another PC , this error mostly pops up when you connect your phone using a USB 3.0 port with windows 8 64-bit, if u can find a PC with win7 with usb 2.0 port it might solve ur problem.please try and let me know

    Okay boys and girls! I have found a simple way to revert back to 11s without having a Phd in computer science and more importantly on a Apple computer. Boot into Cyanogen Recovery and do a factory rest (Note: This will WIPE EVERYTHING from your OPO) and that is it! If that doesn't work drag any CM signed fastboot ROM/OS zip to this program JOxygeninstaller while your phone is in fastboot mode. If you are looking to root your device this method installs an old WORKING version of TWRP & SuperSU once your up and running you can upgrade them to the newest version. I'm posting this because I'm sick of asking for help only to get vague answers or told to shot the intertubes.

    Disclaimer: I'm not responsible if you brick your OPO! I've read somewhere that it is theoretically impossible to brick this device.

    What happens if you get an error message while trying to extract the rom to the sdk folder?

    :edit: I managed to figure it out - guess it was nervousness. :edit:
