    Hey so all this seemed to do was wipe my phone and reflash CM12s?

    Edit: So I did it again, and now I'm back on 11s. Thanks!

    Thanks so much. Worked very well. Adding some additional points. Might come in handy for someone.
    1. Its better to backup
    2. Perform a factory reset to CM 12
    3. Then proceed with the steps
    Just saying...

    Backup your personal pics and other files or contacts is absolutely necessary. But no need for a factory reset, because the process will wipe out everything existing on the device first before installing the stock CM11S rom.

    This is the first time I am doing anything out of stock. CM 12 was giving me Battery issues and slight heating problems. CM 11 was smooth. While following the process the phone got bricked. The post in this forum helped a lot. Sweated a bit but now the phone is back to CM 11. I don't know when the flashing was done. Suddenly the phone switched on with the CM11 starting screen.

    Thanks guys for the wonderful effort and patience for explaining.
    Cheers. Hope Oneplus can sort out the problems and geta good Lolipop version.

    I have tried to rollback to CM11 using attached instruction, but failed.

    My phone condition : I tried to install CM11 using the TWRP, the file unzipped successfullly, but the installation failed. Now my device when turned on always goes to TWRP screen. I can go into the fastboot mode.

    Please guide me how to recover back
    1. How to make sure all the drivers are installed correctly
    2. Do I need to install CM11 firmware
    3. If yes, please let me know how to install firmware
    4. Can I install CM11 using your batch file
