Recover hard bricked OnePlus One12 Apr 2016
In case you damaged the bootloader—e.g. while installing
CyanogenMod or flashing a new version of Android—this instruction will help
you get your phone back to the factory state even if it does not respond to
any input anymore (not even
fastboot via USB).
You will need a Windows PC (if you find a solution for OS X, let me know).
- Download the OnePlus Recovery Tool to restore the stock version of CyanogenMod (CM11s) and follow the instructions there.
- If you encounter a problem with drivers (e.g. your phone is not recognized), which is common with Windows 7–10, learn how to properly install drivers in the Unbrick OnePlus One guide. You might also need to temporarily stop windows automatically installing drivers.
- In case you encounter other problems, consult the Hard bricked thread.
Update to the latest version of CyanogenMod
If the phone does not automatically update to the latest version of Android, you may want to install the latest update manually.
