Would simply flashing those files be pretty safe?
I know with the DHD, I was told to use RUUs as they would be slightly more safe than just flashing a radio, but I don't know if it's the same here.
edit:
alright so I've flashed the DU rom with PA GApps and now I keep getting the popup for "process com.android.systemui has stopped" and then I cant do anything but turn the phone off.
I've tried wiping and reflashing the ROM and that hasn't helped. The second time I tried it, I hadn't changed any settings or used any other mod
