I have a friend who needs access to their deceased brothers locked ZTE Z835 without factory resetting / losing data. They believe there may be evidence on the phone and authorities had already gave up on trying to hack into it. That said, they didn't even seem to think that the authorities had pulled the SD card to check what's there. I gave them an adapter and pointed them in the right direction (without personally diving through files and potentially seeing pictures I do not want to see). Of course, messages are of most importance for them and are not stored on the SD card hence why I'm hopeful the community can point me in the right direction so I can help a friend.

I'm semi technical and have tinkered with rooting in the past just so far behind nowadays that I wouldn't even know where to start (or more importantly, if rooting would help) especially with this not so common device.

I've looked into brute force but one immediate issue is the device doesn't show how many # makes up the Passcode... Native apps such as Dr. Fone... And other options that require the phone to already be rooted...

  • Do you think the USB debugging has been enabled before? If it is, then you can root the phone via PC – HEWhoDoesn'tKnow Nov 5 '18 at 5:55
