If you're already on NE3, messed something up, and want to flash stock NE3, then I think you have to start over and go back to ML2 but I could be wrong. Somebody please correct me if I am.
Somehow Safestrap stayed on my phone after the NE3 OTA update via wi-fi. I always get the safestrap boot screen. After messing with my phone for a week, I used safestrap to continue into recovery and flash a TWRP backup of the phone just after I made the OTA update to NE3. So I did not have to go back to ML2 to get back to my original fresh first boot of OTA NE3. It definitely was different in the aspect that I did not have to go through all the set up screens again, wi-fi etc.. So technically it was not a "completely" fresh install of OTA NE3.
Safestrap remains, always there on boot up after a shutdown. Wish Safestrap to be fixed for loading flashable Slot-1, Slot-2 etc. in NE3 4.4.2. Tried but Slots still do not work, but the flashable backup still does.
, it would be quite a developer accomplishment to create a flashable update.zip similar to the renamed OTA cfg file, that still has the locked BL, but have built in user customizations. Such a basic update.zip could already have a a pre-configured root via towelroot.com.
Anyway just wanted to mention I did somewhat get my 'almost' stock NE3 reinstalled the Safestrap TWRP way.
