Install Custom ROMs on Galaxy S20 FE 4G/5G [One UI and AOSP]

Sadique Hassan•Updated Jun 18, 2024

In this guide, we will show you the steps to install numerous custom ROMs on your Galaxy S20 FE 4G/5G device. The S series from the South Korean conglomerate has always been among the most popular players in town. Offering flagship-level specs and perhaps the best camera that any smartphone has to offer [with Pixel being an exception], its topmost position in the pecking order is hardly a secret.

However, this would then also translate to the fact that it would be on the higher side of the price spectrum as well. And that is indeed the case, with the S series proving to be among the costliest Android phones in the market and breaking the price barrier with each new iteration. Fortunately, there’s also a budget-friendly Fan Editon that gives you the same level of software experience that Samsung is known for without compromising too much on the hardware side either.

Combining all this, it turns out to be the perfect recipe for success, not just for the generic users, even the tech enthusiasts have set their eyes on this device. In this regard, the device was launched with Android 10 out of the box and has already received its fair share of 3 OS upgrades. But guess what, you could even welcome abode the latest One UI 6 based on Android 14 with the help of customized firmware.

Not only that, if the OEM’s underlying OS skin is not in sync with your requirement, then you may even install an AOSP-based ROM and get a clean stock usage experience with a few Pixel goodies. So without any further ado, let’s make you aware of the steps to install numerous custom ROMs on your S20 FE 4G/5G device.

Irrespective of the ROM you flash, it will wipe off all the data from your device, so please take a complete device backup beforehand. Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing the below steps.

Given below are the prerequisites that are required for every custom ROM. So anytime during the flashing process the need arises, you may refer to this section and carry out the desired task.

Unlock Bootloader

Your first course of action should be to unlock the bootloader on your device. Doing so will wipe off all the data and will trip Knox as well.

To begin with, enable OEM Unlocking from Developer Options.
Then connect your device to a PC and boot it to Download Mode.

Boot to Download Mode

After that, boot your device to the Download Mode.
