Install Stock Firmware on Galaxy S20, S20+ or S20 Ultra 5G

Samsung Galaxy S20, S20+, and S20 Ultra are Samsung’s latest flagship smartphones. These phones come with all it takes to be the best smartphone of 2020. The new S-Series collection has outstanding cameras, making it stand out. A few new features are also introduced in the new series. Although the Galaxy S20 is the latest smartphone, there are cases where you might have to install stock firmware on the Galaxy S20. For example, if your S20 is stuck in a boot loop at the startup. You can use this guide even if you want to unroot your S20 and return it to stock.

The Samsung Galaxy S20 comes in three colours: Cosmic Gray, Cloud Blue, and Cloud Pink. The Samsung Galaxy S20 Ultra comes in Cosmic Gray and Cosmic Black.

Following is a little comparison of all the S20 models:

Now, moving back to the topic, you can install stock firmware on Galaxy S20 using two methods. One is via Smart Switch, which is a pretty easy-to-use software used by Samsung to troubleshoot problems with Samsung smartphones. The other method is via ODIN, another official software used by Samsung to flash firmware and recover on Samsung phones.

Install stock firmware on Galaxy S20 via Smart Switch:

Smart Switch is helpful software that allows users to perform several tasks on their Samsung smartphones. You can backup your phone on your PC or cloud and restore the backup using it. It works like iTunes works for iPhones. You can also install stock firmware on Galaxy S20 if it’s stuck in a boot loop. It does not boot after an update, or you want to go stock after you are done with rooting.

Prerequisites:

• Your phone must be charged over 40%.
• A Windows or MAC computer. The smart Switch is not compatible with Linux distributions.
• Data cable to connect S20 with PC
• Download and install Smart Switch on your PC.

Once you are done with prerequisites, Follow the steps below to install stock firmware on Galaxy S20:

1. First, open the smart Switch on your PC and connect your Galaxy S20 to your PC using a data cable.
2. Once your phone is connected, it will be recognized by a smart switch.
3. Click “More” on the top right corner of the smart Switch and select Emergency Software Recovery.
4. Here, you will see two options on the screen: Initialization and Emergency Software Recovery. These options are for when your phone is not booting up. You can use either of the options to install stock firmware on S20.
5. You must have your phone’s model and serial numbers in Initialization Mode. This information is on the back of the phone’s box.
6. In Emergency Software Recovery mode, you must have your phone’s recovery code, which Smartswitch also generates if your PC recognizes your phone.
7. Use either of the methods. Download the firmware that Smartswitch usually uses. Follow the on-screen instructions, and you’re good to go.
8. It might take time as the smart Switch will download the firmware on your PC. Ensure your phone is connected to your PC and the internet during the installation of the new firmware once it is complete. Your phone will reboot.

Install stock firmware on Galaxy S20, S20+ or S20 Ultra using ODIN:

In some situations, you can not install stock firmware on Galaxy S20 using Smartswitch. For example, if the Smart switch does not recognize your phone, you can’t find the recovery code for emergency software recovery or fail to install the firmware on your phone. Your second option is ODIN. For some people, ODIN is the first option. As it gives you more flexibility, you can select the firmware yourself. You can make modifications to how you want to flash the firmware. You can also repartition your phone hard disk using ODIN. If you are not that technical, it is your first time flashing firmware. It might still seem a bit complicated if you follow the information below. It will be pretty straightforward if you get confused during the process. You can reach out to us using the comments or social networks.

Prerequisites:

First of all, you will have to install some prerequisites on your Windows PC.

• You will have to download and install Samsung drivers for Windows.
• Download the latest ODIN3 version 13.4.4.
• Download the Official Stock firmware for Samsung Galaxy S20 from Sammobile. (Enter your Model number and look for the latest stock firmware Android Oreo)
• Your phone should be charged>40%.
• While using ODIN, ensure KIES is off and not running in the background.
• Turn on USB Debugging on your Galaxy S20:
  • Go to Settings -> About Device, -> Tap on Build number 7 times.
  • Now Go back to Settings -> Developer Options -> Turn on USB debugging.

First, download and install Samsung drivers for Windows on your laptop or PC if you have already installed a smart switch. You don’t need to install the drivers, as your PC already has them. These drivers are required for your computer to recognize your phone.

Moreover, download the appropriate firmware for your phone if it is carrier-free. Then, you can download and flash the firmware from any country. If your phone is carrier-locked, then make sure to download the firmware of that respective carrier according to the country in which you bought the phone if you install the same firmware already installed on your S20. All your data will be preserved. Otherwise, you will lose all the data in your phone’s internal storage if you install carrier-free firmware on a carrier-locked phone. Your S20 will be stuck on the Samsung logo at the startup.

Once you are done with the prerequisites, Move on to the step-by-step guide below:

1. First of all, turn off your Galaxy S20 or S20+.
2. Now go to Download Mode.
   • Power off your phone.
   • Once it is completely off, press the Power button as the phone turns on, press and hold the Volume Down and Volume Up keys and release the keys when you see the Samsung logo on the screen.
   • Now, you will see several options on the screen; this is the recovery mode. Use the volume button to navigate to “Reboot to Bootloader” and press the power key to make the selection.
3. Open ODIN and connect your phone using a USB data cable on your PC. You will see “Added” in the ODIN logs.
4. You will see your phone has a connection with your PC. The ID: COM on ODIN will change to blue. (If the colour didn’t vary, the PC failed to recognize your phone. Above all, ensure you have installed the correct drivers and that the drivers were installed successfully. Sometimes, the fault lies in the USB cable)
5. In ODIN, you will see several tabs, and you will have to select files that are respective to each tab. For example, click on CP and locate and select the CP file from the extracted firmware. Similarly, click on AP and select the file with AP in the name. Likewise, add the BL file in the BL tab.
6. Suppose you want to factory reset while installing stock firmware on Galaxy S20. First, select the CSC file in the CSC file. Otherwise, load the HOME_CSC instead.
7. Make sure F.Reset.Time and Auto-Reboot options are checked in the ODIN. Meanwhile, if there is, any other option is checked. Uncheck it.
8. Finally, when everything is ready, press the “Start” button. The whole process will take around 5-9 Minutes. Once done, your phone will reboot.
