    This tutorial will instruct you on how to flash a bacon-signed-fastboot Cyanogen OS factory image on your OnePlus One.

    Fastbooting a factory image is the best way to completely wipe your phone. You will leave no traces of usage after fastbooting. This will bring your phone to a factory-fresh state. Currently the safest way to wipe your phone before selling it or giving it to somebody else.

    OPTIONAL - Make a full backup. This procedure wipes your phone of everything. All your files, media and data will be gone.


    Your bootloader has to be unlocked in order to do this.

    0.5. Boot into fastboot mode: POWER+VOLUME-UP

    1. Download the latest factory image (from the fastboot images section) and extract its contents in the platform-tools folder (or any other directory with the adb/fastboot files in it)

    2. Hold down shift + right click in the folder with the files and click "open command line here"

    3. Type in all these commands in order one at a time (some of them may take some time so be patient)

    fastboot flash modem NON-HLOS.bin
    fastboot flash sbl1 sbl1.mbn
    fastboot flash dbi sdi.mbn
    fastboot flash oppostanvbk static_nvbk.bin
    fastboot flash aboot emmc_appsboot.mbn
    fastboot flash rpm rpm.mbn
    fastboot flash tz tz.mbn
    fastboot flash LOGO logo.bin
    fastboot flash boot boot.img
    fastboot flash cache cache.img
    fastboot flash recovery recovery.img
    fastboot flash system system.img
    fastboot flash userdata userdata.img (or userdata_64G.img)

    Be aware: The COS12 factory image may not have a userdata_64G.img file. In that case, you will have to download the CM11S ZIP (same link) and use the userdata_64G image file from there. If you flash a 16GB data partition on a 64GB phone, your will have 16GB of internal storage.

    fastboot reboot

    OPTIONAL:
    Boot back into fastboot mode and relock your bootloader by executing fastboot oem lock.


    That's it! Your phone is now in factory state! You can now sell it or dump it without worrying about your precious data. Enjoy!

    It will not help you in all situations.

    If it works it means you didn't had serious problems, trust me :D

    It's just the way how to flash a factory image on most every android device. You can probably find it in every language forum here :D

    Maybe you would be better off searching next time

    I've pinned this for now in this forum. I'll look into moving it into Dev or cm11s in a little bit.

    Please note I can't enable the USB debugging within the phone so will this method still apply as I'm stuck on the bootloop.
    Question is whats the difference between bacon-signed-fastboot.zip and bacon-boot-debuggable.img?
    And would I be updated to 38r afterwards?
    Last thing, I keep seeing wiping the delvik cache is needed, how do I do this?
