Note to all users:
Nokia has fixed the hole where current HelloOX2 using to Hack the phone on the newest N86 firmware20.115. We almost sure all the upcoming firmware on other models will also be UnHackable likeit.
However, from our experience, updating a Hacked phone firmware on PC with “Nokia Software Updater” or on phone with “FOTA” will not erase all your installed files and settings, of course the Hack willstill be there too. But all of them will gone when you do a factory reset, your phone will not be Hackable in the near future until a new Hacking method found. (note: v2.03 UnHack function will remove all Hack and then become UnHackable too, don’t use it on UnHackable firmware!)
If you would like your phone keep Hackable, please do not update! If you would like to update your Hacked phone and keep it Hacked, please do not do factory reset! The safer way is wait for some more users report before update, becauseupdating a Hacked phone will also be Hacked were just an experience, we’re not sure is it also the same onall upcoming firmware.
