change device props

[Yamin Elmakis]

hey,
i have an Android x86 4.4.4.
i'm changing the /system/build.prop file and i see the changes saved in the file even after reset.
but the properties of the device stay as they were befor the change when i check them in the device settings.
is there any why the device is overriding the build.prop data?

What properties did you change exactly?
Some properties have special meanings in android.
For example, persist.* properties will be stored in data partition.

ro.product.model and ro.product.manufacturer
are set by init according to the dmi code.
They are read-only (ro.*) properties that
can't be changed later in build.prop.
If you want to change them,
you need to modify the init.x86.rc
in the ramdisk.

tnx.

can you please tell me what is the path to init.x86.rc?

can i change all 4 properties from that file?

[Yamin Elmakis]

i managed to change the manufacturer and model..

but do i change the characteristics?

how do i make the tablet think it is a phone for example?

[Yamin Elmakis]

i sew that the product chatacteristics is set to tablet in the file device/generic/x86/device.mk

PRODUCT_CHARACTERISTICS := tablet

but this file is being ignored in the build.

can anyone help me and point me to the relevent file?

Why did you think it's ignored?
That's exactly how ro.build.characteristics is set.

Note if you change the variable,
you'd better to do a clean build
to ensure everything is rebuilt properly.
(it's hard to explain the reason. But if you understand
the android build system, you know why)

Hello, can you please tell me how you made the changes? I am pulling my hair off trying to do this too.
Thank you.

how you changed the manufacturer name in androidx86??

[youling 257]

edit default.prop，you have to modify ramdisk.img ，zcat ramdisk.img | cpio -id > /dev/null ，find . | cpio -o -H newc | gzip > /sdcard/ramdisk.img 

ro.product.model=Pixel XL

ro.product.manufacturer=Google

ro.opa.eligible_device=true

this works perfect in android 4.x and android 5.x , but what about android 6.0.1 ?

[youling 257]

of course，edit default.prop，work well on 6.0 and 7.1 .

but use magisk resetprop is nice .

/data/magisk/resetprop ro.product.model "Pixel XL"

/data/magisk/resetprop ro.opa.eligible_device true

/data/magisk/resetprop ro.product.manufacturer Google
