There is a paradox with shopping for mobile phones that you think will be best suited to having a custom ROM installed and what phones are best for having them installed. The fact is that most great Android developers who create the custom ROMs do so where there are the largest crowds. These groups tend to flock to the best and most expensive devices, and that’s why you get so many great ROMs available for smartphones like the HTC flagship series. The irony is that people usually have little interest in installing a custom ROM on an expensive device because they don’t want to risk bricking the device. Installing a custom ROM offers the most risk-reward you can get in any device customization. You will not find anything that changes your device as much as a new ROM, but at the same time, you won’t find anything that comes with a higher risk either.

The HTC One M7 smartphone is now so old that most people care little about bricking because it’s not worth much money anyhow. That makes it the perfect time to start installing a custom ROM on your M& smartphone.
