Then do a local update.

Plug in your phone, and enable usb debugging
Get ADB, then shift + rightclick the folder and select open command prompt here.
adb reboot bootloader
fastboot flash recovery recovery_twrp.img
After that, reboot your phone in recoverymode and flash gapps. At reboot, it will ask you if you want to root. Do that.
Hope I helped.
Sent from my P6-U00 using xda app-developers app
But a cant boot into adb if i have twrp
Edit: have it, missed drivers-hisuite helps
