In this guide, we will show you the steps to go back to the stock ROM from a Custom ROM on Samsung. One of the biggest perks of entering into custom development is welcoming abode a customized firmware on your device. In the case of Samsung, you could try out a clean stock AOSP experience such as LineageOS and crDroid or the one based on One UI such as Dr. Ketan’s ROM which are much more enhanced and performance optimized than the stock counterpart.
However, this is just one side of the coin. As opposed to official stock firmware, these Custom ROMs are usually buggy in nature with a few underlying issues. Even if they get rectified in one build, a few new ones sneak into the next build. Apart from that, sometimes a developer tends to suddenly stop the support for its ROM.
While we respect their decision [as they don’t benefit from these ROMs, financially or otherwise, on the flip side, they have to put in their valuable time and effort], but let’s think for once from the user’s point of view- they are left in the lurch with no way out. In such instances, their best bet is to revert to the stock ecosystem or flash another custom ROM.
If we talk about the latter, then it’s never advised to directly flash one ROM over another, you’ll first have to flash the stock firmware before moving over to the next custom ROM. In all these cases, one thing stands in common- you’ll have to go back to stock from the custom ROM on your Samsung device. And in this guide, we will show you how to do just that. So without further ado, let’s get started.
How to Go Back to Stock ROM from Custom on Samsung

STEP 3: Extract Firmware
Once you have downloaded the firmware, extract it to any convenient location on your PC. This will give you the AP, BL, CP, CSC, and Home CSC, out of which the first four files will be flashed. Moreover, we will be using CSC instead of Home CSC because a data wipe is a must when it comes to going back to stock from a custom ROM on your Samsung device.
