Hello,
I have Huawei P9 Prime (STK-L21) with FRP Lock, USB Debugging mode disabled and locked bootloader.  Using Android 9.0 so the device is encrypted by default 
HiSilicon Kirin 730F Chipset

The device is 6 digit PIN screen locked.

Any Suggestion for  JTAG or ISP?

Are we able to root the device with some exploit?

Is this a possibility to get some user data from this model or to bypass the screenlock? 
Maybe some exploit for this kind of chipsets ?

 

Best Regards

Oxygen should support this phone for keys extaction with testpoint, then bruteforce the passcode.

Oxygen itself. First you do the extraction, entering COM 1.0 mode using testpoint. Oxygen will make full memory chip image and extract encryption keys. Then, once you load the extraction into Oxygen it'll ask for a passcode or allow you to bruteforce it directly. It's using Passware for the job.
