In this guide, we will show you the steps to go back to stock ROM from any custom ROM on your Samsung device. While the devices from the South Korean giant are not the most active players when it comes to custom development, still, it isn’t the least favorite among tech enthusiasts either. It has managed to maintain a middle ground and usually gets blessed with numerous One UI-based and a few AOSP-based ROMs.
However, custom ROMs are known to have a few underlying bugs and issues, which even though get ironed out in the next build, but the new ones tend to make their way in the subsequent build. So is a vicious cycle with no way out. Apart from that, there have been a few instances wherein a developer decides to end support for their ROM.
While we completely respect their decision [as most of them aren’t earning anything from these ROMs but instead have to put in their valuable time and efforts], however, it creates quite a few problems for the end users. The biggest among these is the fact that since the ROM is no longer being developed, it will no longer be on the latest security patch, which will spell out a major security and privacy risk.
Apart from that, if you are currently facing any issues, then it will no longer be fixed as it’s not being maintained. So in such cases, your best bet is to revert to the stock ROM or flash a different custom ROM. If we talk about the latter, then it’s quite a risky approach to directly jump from one ROM to another.
Instead, a much safer approach is to first go back to stock from your current custom ROM and then make a switch to a different ROM on your Samsung device. So in all these cases, going back to the stock ecosystem is a must. And in this guide, we will show you how to do just that. So without further ado, let’s get started.
