Creating a custom ROM from an existing ROM

Hi

I wanted to know if it's possible to create a custom ROM from an existing ROM, for example I rooted my phone and uninstalled a few system apps, now I wanna make it into a ROM so then i can flash it to the phone and even when someone will factory reset the phone it will still be without the system apps I uninstalled cause the ROM does not have these apps.

Thanks
 
Your posting indicates you want to create a 'cloned image' of your device, an actual Android ROM being somewhat similar to what your intentions but by definition a different thing. You might find it more suitable to try altering an existing ROM for your device, and then recompiling that into a new, custom ROM. XDA Developers has a tutorial on this:

but this might also be worth perusing through:

Read through those links to get a better concept on what an Android ROM is and how this relates to your initial posting. Also, keep in mind that Android is its own platform, applying concepts on things like hard drive cloning need to be considered from a different point of view. Disk duplication with a typical Windows PC can readily done because there are multiple interfaces in play (i.e. multiple drive media connecting to inter-connected,multiple serial and/or parallel ports) but with your typical Android device it's more limited and isolated.
What phone model do you have and which version of Android is it running? There's a significant contrast between older Android devices and newer ones. It's not just a matter of faster, more robust processors and such, but things like partitioning schemes vary between the different manufacturers and with different versions of Android itself.

I have the palm pvg100 running on Android 8.

So I have to Port the ROM, clone the ROM?

Thanks
 
TWRP is a well-supported, third-party Recovery and for a lot of phones is a recommended option when rooting a phone. I'm not sure if TWRP is supporting your model though so be wary. XDA Developers is a good source for rooting info and such, there's active activity for your phone and you might find it worth perusing through the user comments.

If you flash TWRP on a locked bootloader you may end up bricking your device. Also, the root method in the link is a recent exploit (2019-12-17, 9:15PM) and chances are, you'll not find a custom recovery for your specific device just yet.

But is my bootloader locked or not?

I real couldn't answer that with any certainty. If I had to guess, I'd say its locked simply because of how they went about the process and method by witch root was acheved. You best bet is to ask that question in the XDA thread.
