RAM and parts info

[E3lleyyaa]

Hi!
Is it possible to obtain information about the amount of RAM installed on a device? Additionally, can information be gathered on specific components, such as the camera or display, including their factory IDs and current IDs, to check if they have been replaced? I am looking for something similar to an OEM Check, like what many apps offer.

I'm not sure which of these values can be obtained. I guess most of them are available via IORegistry. Try to locate them in the DeviceTree and query using pymobiledevice3 diagnostics ioregistry

[E3lleyyaa]

Ok,will try

@doronz88 Other commands work as expected.

[E3lleyyaa]

Do you have the list of avaliable ioclasses?

[doronz88]

You need to supply with the correct options to get an output.
You can dump the available values via sysdiagnose on-device

@E3lleyyaa curious to know if you found a way to collect this information? I'm looking for installed ram specifically.

I have found some fields like DRAM in certain ioreg classes, but their values are not comparable to the amount of installed memory, as they mostly represent memory cell indices.
