Enable adb locat stdout for Huawei Android Phones

It takes me some time to find out how to enable logcat output for Huawei Android devices.

The method is simple

There are a tempway and a permway

the temp way is :

echo 1 > /sys/kernel/logger/log_main/enable

echo 2 > /sys/kernel/logger/log_main/priority

and the perm way is to modify init.rc file which is located in ramdisk

This way is harder than the temp way.you need to unpack the boot.img to get the ramdisk.then unpack the ramdisk

and modify the init.rc file with this:

write /sys/kernel/logger/log_main/enable 1

write /sys/kernel/logger/log_main/priority 1

in the right place of the init.rc file.

then repack ramdisk --> repack boot.img

then flash the new boot.img to your phone.

That's it. all set.

sweet log cat is back to you.
