I would like to find out if its possible to modify the firmware of a smart phone in one of two ways: 1) changing a phone's identify essentially fooling it into thinking is a superior model, for example, making a Huawei P20 Lite think its the pro version OR 2) forcibly upgrading the current android software to a newer version, in my case, from Android 9.0 / EMUI 9.1 to Android 10 / EMUI 10. I've tried to do research and find sources to assist me but I haven't found anything.
My reasoning for option one is that I would be able to download the official EMUI upgrade a lot sooner and I imagine it would be the safer option. However, if that fails, I guess option two would omit the in-between hassles and upgrade it directly to the newer EMUI / Android version.
I am extremely eager to get the universal dark mode on my phone and unfortunately, these third party dark themes just aren't working for me.
Any assistance is greatly appreciated
