My device is Oneplus One, I installed Android 7.0 on it, then I installed OxygenOS 3.1.3. Then I thought to get back to CyanogenMod 13.0 with SultanXDA 3.4.0 kernel.
I've got bootloop, but I still don't know why.
I've noticed that my TWRP version was 126.96.36.199 (by Tugopower) so I wanted to reinstall it using the original TWRP recovery 188.8.131.52 image.
I installed TWRP successfully and pressed Reboot -> Recovery but after that I can't get access to TWRP anymore.
Fastboot says that USB Debugging is disabled.
How can I enable USB Debugging in this situation?
