Huawei Mediapad M5 pro (huawei-cameron)
| This device has been archived. This means that it no longer appears in pmbootstrap and is likely broken. It can still be selected in pmbootstrap init by typing in the vendor and codename, but you will have to build the kernel package manually. |

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:
- Get mkbootimg and unpackbootimg i.e. from here.
- 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-cameron/boot/boot.img-huawei-cameron . $ # extract the created boot.img $ mkdir pmos-boot-huawei-cameron $ unpackbootimg -i boot.img-huawei-cameron -o pmos-boot-huawei-cameron/ $ # copy created boot image to current directory $ cp ~/.local/var/pmbootstrap/chroot_rootfs_huawei-cameron/boot/boot.img-huawei-cameron . $ # extract the created boot.img $ mkdir pmos-boot-huawei-cameron $ unpackbootimg -i boot.img-huawei-cameron -o pmos-boot-huawei-cameron/
- Use the extracted files in the following steps.
- Create ramdisk image:
$ # create new ramdisk image with empty kernel (empty.file size is 0) $ ./android-unpackbootimg/mkbootimg.py --kernel empty.file --ramdisk pmos-boot-huawei-cameron/boot.img-huawei-cameron-ramdisk.gz --cmdline 'buildvariant=user' --os_version 8.0.0 --os_patch_level 2018-06-05 -o pmos-cameron.ramdisk.img
- Create kernel image:
$ # kernel (with empty.file size is 0): $ mkbootimg.py --kernel pmos-boot-huawei-cameron/boot.img-huawei-cameron-zImage --ramdisk empty.file --cmdline 'loglevel=4 initcall_debug=y page_tracker=on slub_min_objects=16 unmovable_isolate1=2:192M,3:224M,4:256M printktimer=0xfff0a000,0x534,0x538 androidboot.selinux=enforcing buildvariant=user' --base 0x0 --kernel_offset 524288 --ramdisk_offset 130023424 --second_offset 15728640 --tags_offset 0x7a00000 --os_version 8.0.0 --os_patch_level 2018-12 -o pmos-cameron.kernel.img
- Flash ramdisk and kernel with fastboot:
$ fastboot flash kernel pmos-cameron.kernel.img $ fastboot flash ramdisk pmos-cameron.ramdisk.img
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.
-> 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
For now the backlight is completely dark when the system boots.
