Gsmart i120 updating rom
If you run into big trouble and you've added a custom ROM build, your manufacturer and carrier likely won't help you out.
In most cases, you'll be able to overturn any ROM you flash, returning to the phone's stock Android OS with as much ease as you installed the new ROM in the first place.
However, a word of caution: If you're not careful, or don't follow the steps properly, you could end up with a glorified paperweight. It's vitally important that you exercise caution when attempting to root your phone and pay close attention to what you're doing.
Stick to the more reputable sources for help and feedback, and look for the most recent news about ROMs and your particular Android device.
I also suggest checking Google as a good source for rooting and modding news and feedback.
One of the more common reasons to root a phone is to replace the operating system with a ROM, another developer's version of the OS that also gives you more control over details.
In rooting culture, we'd call that "flashing a custom ROM."The process of rooting an Android phone varies for each device, but seems to have been streamlined over time.
Deleting apps you'll never use can also free up some additional storage capacity.
Another main benefit of rooting is to enable faster platform updates.
