    fastboot flash recovery twrp-x.x.x.img(name may change depending upon your file)
    try following command :
    fastboot boot twrp-x.x.x.img(name may change depending upon your file)
    Please leave a feedback once done.

    I had some issues with the MacOSX Toolkit myself, but it did a few tricks that helped me along.
    1. The toolkit was not successful in unlocking the bootloader.
    2. Installation of TWRP was not successful even though the toolkit reported that it was.
    3. I could not root because of the first two issues.
    I used the toolkit (Option #7) to install the Fastboot and ADB drivers for the Mac because the versions I downloaded from the Android Developer site were not compatible with my OS version (Snow Leopard).

    Then I just used terminal command prompt to run the fastboot and ADB commands manually. Not the toolkit running inside terminal.

    This guide details what commands to type into terminal. See section 2. This did successfully unlock my bootloader. But I had other issues so I decided to go back to stock and start over.

    If all you want to do is go back to stock, use the MacOSX Toolkit's option 4 to do it, but do not choose a ROM you downloaded. Instead, Choose the option that allows the toolkit to download the stock ROM for the OPO.

    I did this and it worked without error or issue.

    After that, you can go back into terminal and run the aforementioned Fastboot and ADB commands (see section 3 of the guide) to flash TWRP and/or whatever else you want to do.

    Good luck.

    @DaxNagtegaal Sorry noob question - couldnt find it here..Does the kernel depend on the OS version only or the ROM also?
    i want to try color OS and heard its battery life aint that good so wanted to try a custom kernel.

    My oneplus one is stuck on cyanogen boot screen after doing factory reset also.
    From the logs its showing CM 12.1 25th Aug release. I do not have USB debugging enabled, so no adb.
    I tried doing fastboot boot twrp- and can see twrp. Can I use this to flash a new ROM(without having ADB)??

    Stupid question:

    Booting into TWRP is just holding the power and volume down button at the same time right?

    I hardly ever post in the forum, but this post was absolutely amazing. I've always wanted to know how to install a different os (aside from some toolkit), install a different recovery, root, and use Titanium. Thank you so much for writing/collecting all of this!

    I flashed H2OS. But there was no network. So restored my nandroid backup. But still there is no network.
    So I dirty flashed my previous rom(the same one in the nandroid backup),still no luck.
    Then I tried flashing the EFS fix from OP and I'm still stuck with no network.
    Then I flashed latest COS12.1 official build but still there's no network.

    Now I don't have my EFS backed up. What things can I do? Am I going to get my network back?

    Flash TWRP within TWPR, reboot to recovery again and see that the version has changed:

    Then flash OnePlus official Firmware:

    Then dirty flash your current ROM

    After spending half a day on YouTube watching outdated tutorials on rooting my OnePlus One and achieving only partial success, I found this thread and my salvation! I thought YouTubers knew everything (heh!) but I realize I should've came here first...duh! Thanks Dax!
