How to enter flash mode

With power off, press power und volume-down at the same time, with the usb-cable plugged in.

How to flash

As Huawei changed the partition layout, there is no boot partition anymore. Instead there is a ramdisk and a seperate kernel partition. In order to create the correct images the following steps need to be done:

  1. Get mkbootimg and unpackbootimg i.e. from here.
  2. You can extract the kernel-image and ramdisk from the created boot.img with unpackbootimg.
    $ # copy created boot image to current directory 
    $ cp ~/.local/var/pmbootstrap/chroot_rootfs_huawei-leland/boot/boot.img-huawei-leland .
    
    $ # extract the created boot.img
    $ mkdir pmos-boot-huawei-leland
    $ unpackbootimg -i boot.img-huawei-leland -o pmos-boot-huawei-leland/
    
    Use the extracted files in the following steps.
  3. Create ramdisk image:
    $ # create new ramdisk image with empty kernel (/dev/null) 
    $ ./android-unpackbootimg/mkbootimg.py --kernel /dev/null --ramdisk pmos-boot-huawei-leland/boot.img-huawei-leland-ramdisk.gz --cmdline 'buildvariant=user' --os_version 8.0.0 --os_patch_level 2018-06-05 -o pmos-leland.ramdisk.img
    
  4. Create kernel image:
    $ # kernel (with empty ramdisk via /dev/null):
    $ # make sure boot.img-huawei-leland-zImage is gzipped or do it manually before mkbootimg.py
    $ mkbootimg.py --kernel pmos-boot-huawei-leland/boot.img-huawei-leland-zImage.gz --ramdisk /dev/null --cmdline 'loglevel=4 coherent_pool=512K page_tracker=on slub_min_objects=12 unmovable_isolate1=2:192M,3:224M,4:256M printktimer=0xfff0a000,0x534,0x538 androidboot.selinux=enforcing buildvariant=user' --base 0x00478000 --kernel_offset 0x00008000 --ramdisk_offset 0x07b88000 --second_offset 0x00e88000 --tags_offset 0x07988000   --os_version 8.0.0 --os_patch_level 2018-12 --pagesize 2048 -o pmos-leland.kernel.img
    
  5. Flash ramdisk and kernel with fastboot:
    $ fastboot flash kernel pmos-leland.kernel.img 
    $ fastboot flash ramdisk pmos-leland.ramdisk.img
    
  6. Flash rootfs to sdcard to boot it

Additional Kernel Configuration

OASES

About

OASES stands for Open Adaptive Security Extensions. Its a Tradmark of Baidu and seems to have something todo with adaptive kernel live-patching. For now there were no disadvantages from disabling it.

Location in menu

-> Device Drivers
   -> Huawei Platform Drivers
      -> Huawei platform drivers support (HUAWEI_PLATFORM [=y]) 

In Order to compile the kernel OASES had to be disabled.

Additional Info

The display brightness can be set by writing a value between 0 and 9960 to /sys/class/leds/lcd_backlight0/brightness.

$ sudo -i
# echo 1024 > /sys/class/leds/lcd_backlight0/brightness
