[Q] Basic(?) rom modding? Please do read... - Android Q&A, Help & Troubleshooting

Hello! I'd like to ask the community about something I've been interested doing as a project for a phone I plan on buying, I've looked around and I see lots of tutorials, but they don't quite meet the very specific criteria.
My problem is that I want to buy the "Umi C1" (click click for more info o: ) and the UI on the Stock ROM is awful.
I've looked around and there's apparently a way to modify ROMs using another phone's ROM files.
I was thinking of using the "HDC ONE M8's"(fake HTC one m8) ROM files and transferring them over to the C1's ROM file. (Both phones run the MTK6582 SOC, both have 1GB of RAM, Both have 16GB of storage, both run 1280x720P panels...)
Is this in anyway possible? Both roms are Odexed. (new to this, looked around on how to deodex roms and found a tutorial but I'm not sure how things will go first.)

Hello!
You can't move the whole content of a ROM made for a specific model, to another ROM made specific for a different model.
The reason for this is because the ROM also contains native libraries (drivers) that are specific to the hardware of the phone, and are not specific to the Android base code.
In other words, you would need to port the UI and framework only, not simply move all the files and even this is not very straightforward unfortunately. If you only want some minor (or major) changes of the home screen and application menu, then there are plenty of third party launchers on the market that should do the trick for you.
I hope this helped you.
