I am relatively new to rooting and stuff. I have just rooted my android tablet. It's a Chinese tablet, not much about it is available on the internet.
Can I install ROM for another device on my tablet? I saw many videos on YouTube showing "How to install any ROM on any Android device". Does 'any' here mean that I can install, let's say, a Nexus ROM on my tablet?
Is there some generic ROM which can be installed on all androids? If so, can I install this generic ROM and then upgrade to a ROM of another device?
If no, is there a way to do so? (If not, then how do manufacturers put their ROM for the first time?)
