Some ways to unlock old huawei devices with qualcomm soc and need help

[hicode002]

For some old huawei devices,they did not configure secure boot correctly(not fused)，for example ,all devices with msm8916 msm8909 and some devices with msm8953.They just used the modified sbl to verify the signature of the Aboot partition header (using RSA), and then configured the bootloader lock inside the Aboot.
So we can directly patch sbl, skip the verification of aboot, and then use lk1st or Qualcomm's original lk to port the display panel driver, which can unlock the bootloader.

Here is an example.
