This is on a fresh win8 installation. This is what I did.
Install your software.
Did the full driver installation..
Clicked unlock
it did its thing got to the unlock bootloader screen on n10 just fine...then when got to "booting into twrp temporary to factory reset is when it asked for password..I actually debated taking a picture but wanted to finish what I started..
so after trying it a couple times each time it asked for the password, frustration hit. so went looking more with software to see if can use different recovery.
so in prefrences switched the temp recovery to cwm touch. yet the unlock process still went to twrp.
so went to advance utilities and was able to launch cwm touch temporary using that.
factory reset in it.
went back to main screen of your software
clicked root..and was able to finish up the process..
sorry havent got on gchat...sick kids make life difficult
