Now it's more and more difficult for forensic tools to extract evidence from smartphone running Android 7 and above. Maybe you could acquire physical image in Bootloader mode or by Smart ADB. Don't celebrate too early. Let me remind you of "FDE". The fact is that if forensic tools could not decode this physical image, such image is just like a meaningless "black box" you have in hand.

No way to gain root privileges from phones running Android 7 and above . What else can be done? Fortunately once you got the pattern/password , you could enable USB debugging and change any settings you want to make "Downgrade extraction" possible. That's the key to get the evidence from certain Apps you want.

Let's take WeChat on a phone running Android Pie for example. You guys could take a look at my blog and see what's going on.

Thank you for the step by step instructions to install a downgraded version of WeChat to enable the .ab backup and extraction.

Question How are you achieving “once you got the pattern/password?”?

Not true, it is possible. Not everybody knows how, but that's something else…

"In case of devices with know user lock" would fit better.

In case of locked devices, contact me D

Yes, you guys are right. In my opinion, law enforcement should try every effort to get username/password. If suspect'd like to cooperate with LE, we could ask suspects to tell us what the username/password is. That will be easier, right?

Of course we all know that it's not easy to unlock phones running Android 7 or above. That's why such services like CAIS costs lots of money not everyone could afford.

More and more phones got Bootloader Lock so we only got few chances to gain root access on Android 7 or above. Why bother to take risk of losing data? I suggest we take advantage of qualcomm EDL mode to bypass BootLoader and remove pattern/password lock. A very interesting video about removing pattern lock under so called qualcomm 9008 mode as below.
