TWRP: Wiped phone, can't put any data onto it through MTP So I wiped my phone because I was going to install Cyanogenmod 12 (Nexus 5) but now it is wiped I can't make any folders or move any ROMs onto the phone through MTP even though it shows in Windows.

How can I fix this?
I had the same issue with MTP not working from TWRP (Windows 10 x64). I used adb push as a workaround way to put update on the phone after disabling MTP from TWRP "Mount" menu:

adb.exe push update.zip /sdcard
adb push open_gapps-arm64-7.1-nano-20170625.zip /sdcard
