A friend of mine has a problem with his OnePlus One:
After (maybe even before, I'm not sure) he installed ColorOS, the fastboot mode hasn't been able to flash a new recovery (TWRP).
It just says OKAY after a part of a second, but then it just stays inside the bootloader doing nothing. The system didn't even indicate that it's downloading the file or something.
So I thought, the ColorOS recovery might also be able to install CyanogenMod, so I tried that too. Installation failed. That's a pretty strange recovery, by the way.
Has any of you got any idea on how fix this problem? I am looking forward to reading answers concerning that issue.
Thanks in advance!
