Huawei P9 (PRA-LX1) Screen Lock Bypass

Post Posted: Jun 12, 18 12:18

Hello,
I have Huawei P9 Lite (PRA-LX1) with FRP Lock, USB Debugging mode disabled and locked bootloader.
Based on gsmarena it is:
Android 7.0 so the device is encrypted by default
HiSilicon Kirin 650 Chipset

The device is PIN screen locked.

JTAG or Chip-off gives me encrypted raw image so it's useless.

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

(I dont have access to Cellebrite UFED)

NO, IT IS NOT USELESS, IF YOU CAN PROVIDE THE DEVICE AND A PHYSICAL DUMP OF IT'S EMMC, WE MIGHT BE ABLE TO ACCESS THE USER PARTITION DECRYPTED!!!

I also wrote "we might be able to access the user data partition decrpyted". We can be 100% sure only after the success doing it is achieved Smile

We can offer you a workaround. 1. You can check if there is a Huawei backup on SD card. 2. If you have access to the user's PC you can also check if any HiSuite backup was made there. Both types of backups can be imported into our Oxygen Forensic Detective software. What is good about these Huawei backups is that they contain a great amount of evidence including app data, internal memory files and deleted records.

No, there is nothing more than the phone. It was never used with any computer. No SD card used ever.
