Android 8.1 userdebug的固件在输入adb root adb remount 之后会有这样的提示。

C:WUsersW .KH>adb remount
dm_ verity is enabled on the system and vendor partit ions.
Use "adb disable-verity" to disable verity.
If you do not，remount may succeed, however, you will still not be able to write to these Volumes.
remount of /system failed: Read-only file system
remount failed

意思是需要输入adb disable-verity之后，重启机器，然后再adb root adb remount之后，
才可以adb push 到system

怎样默认disable verity呢，我看了一下网上的介绍，修改了这几个地方，就OK了。

(1)在build/target/product/verity.mk中，将
PRODUCT_SUPPORTS_VERITY := true
PRODUCT_SUPPORTS_VERITY_FEC := true
改为 :
PRODUCT_SUPPORTS_VERITY := false
PRODUCT_SUPPORTS_VERITY_FEC := false

(2)在/kernel/{arch|arch64}/{arm|arm64}/configs/{Project}defconfig中，
将CONFIG_DM_VERITY=y改为 :CONFIG_DM_VERITY=n
添加：CONFIG_MTK_DM_VERITY_OFF=y

3.在 system/core/fs_mgr/Android.bp
product_variables: {
debuggable: {
   //cppflags: ["-DALLOW_ADBD_DISABLE_VERITY=1"],
cppflags: ["-DALLOW_SKIP_SECURE_CHECK=1"],
   },
eng: {
   cppflags: ["-DALLOW_SKIP_SECURE_CHECK=1"],
},
},
参照eng的修改debuggable，改为DALLOW_SKIP_SECURE_CHECK=1
