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 )

Any updates with bypassing lockscreen on this Huawei PRA-LX18.0.0.401? Phone locked, FRP lock. Android 8.0

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.

Is it that really hard to bypass lockscreen on Huawei devices?!!
EFT Dongle team introduced a way to do that before and it's actually functional but with some circumstances.
What about other models that it EFT don't support?! Like this one

With FRP on, OEM locked and phone locked Huawei devices you can't flash nothing on the device, other then Huawei signed binaries.

The EFT dongle or similar solutions won't work, since you can't change the boot.img or the kernel.

The dload method using a microSD card IS working indeed, just once again, you need Huawei signed binaries.

We got a solution by now for opening mostly every Huawei device, just it costs some money.

Although i never actually tried it, i think EFT uses a SystemUI method for Huawei so it "patches" system partition image and doesn't touch boot.img at all. Personally, i was unable to flash any single Huawei in fastboot with EFT.
