Install stock firmware on Samsung Galaxy Z Flip 3

Samsung just released its new foldable phone in the series of Samsung Galaxy Z. Folding of a touch screen is a new feature, and it’s getting better and better with time. If folding phones is what we are looking at in the future, then the tech has to get better and better to the point where folding a phone is just another feature. It has to be a regular phone with all the other smartphone features with a foldable screen. The Galaxy Z Flip 3 gives you all you would expect in an Android smartphone. In this guide, we will talk about the software of the Samsung Galaxy Z Flip 3. If you either rooted your phone or it’s not working correctly, you are looking to install stock firmware on Samsung Galaxy Z Flip 3. You have come to the right place.

This year’s Z flip model features make the phone much more useable. First, the new design, the much improved built quality, and the more prominent and useable outside screen make it feel more refined. It comes in sweet green, matte black, and creme color. It makes a square when it’s folded, which is pretty cool. Alongside, the new phone is now waterproof, yet you should keep it away from sand and dust. The Samsung Galaxy Z Flip 3 comes with a big display, almost the size of the Galaxy S21 Ultra. It has a 6.7-inch display screen. 22:9 1080 pixels and its 120 Hertz refresh rate finally. Another cool feature is using the camera via the secondary screen and taking pictures while the phone is folded.

What is Stock Firmware, and why you might have to flash it on your Samsung Galaxy Flip Z 3?

A stock firmware is an operating system (software) that comes from the smartphone manufacturer itself. In this case, Samsung deploys a tweaked version of the Android operating system for its smartphones. Unfortunately, these operating systems sometimes get corrupt, or the phones are not performing as they should be, eating loads of battery, shutting down in the middle of working, and being stuck at the startup on the Samsung logo. All these signs suggest that there is something wrong with the operating system. While the first and foremost task to fix these problems is via factory reset. But, if even that does not help, the final solution to fix software issues is via flashing the stock firmware.

Another reason to install stock firmware on Samsung Z Flip 3 might be if you have rooted your phone or installed custom firmware, and now you want to go back to the factory setting and stock firmware. So you can get the software updates from Samsung.

Remember that installing stock firmware on Samsung Z Flip 3 doesn’t trigger the Knox.

Smartswitch is an official tool for troubleshooting problems with Samsung smartphones. It allows you to install the firmware, factory reset, make a backup of your phone on your PC, and you can also migrate from one phone to another using Smartswitch. Today, we will use smartswitch to flash stock firmware on Samsung Galaxy Z Flip 3.

Smartswitch is very user-friendly. Even people with no technical expertise can use it. All you need to do is install the smartswitch on your Windows PC or Macbook and follow the on-screen information, as the other method isn’t for computers running on macOS. So, this solution is your only rescue option if you have a MacBook.

In the guide below, we will be using smartswitch for flashing stock firmware on Galaxy Z Flip:
  • First of all, you need to download and install Smartswitch on your Macbook or Windows PC.
  • Once installed, connect Samsung Z Flip with your PC via a data cable.
  • Open smartswitch. Once your phone is detected, the tool will display all the information about your phone on the screen.
  • In the top right corner, on the taskbar, you will see “More.” Click on it and select “Emergency Software Recovery.”

Note: Smartswitch might ask for a recovery phone. Suppose your phone is stuck at bootloop or unresponsive. You might not be able to get the recovery code in such circumstances. Instead, you can use the “Device Initialization Mode.” For that, you will need your phone model and serial number. You can find this information on the box of your phone.

Install Stock firmware on Samsung Z Flip 3 via ODIN:

If your phone is totally unresponsive, or you want more control while flashing firmware. ODIN is a better choice. ODIN allows a Samsung user to perform multiple operations on a Samsung phone. Using ODIN, you can do a repartition of your phone, install a custom recovery, or a custom ROM. You can also fix your phone if it’s soft-bricked or hard-bricked. The only downside is that ODIN is a bit technical. However, once you are familiar with the tool, it is handy.


  • Make sure your phone is charged before starting the process.
  • Download and install Samsung Drivers for Windows on your PC.
  • Download ODIN 3.14.4
  • You will have to download the appropriate firmware for Galaxy Z Flip 3. You can download it from Sammobile or any other website with Samsung smartphone firmware. Once the firmware is downloaded, extract it on your PC, where the files are easily accessible.
  • Make sure you download the appropriate firmware for your phone. Although, you can install firmware from any country on your phone as long as the firmware and the phone are not branded. If your phone is of some brand and it’s locked to the brand. Then find and install the firmware of that brand, e.g., T-Mobile, Vodaphone, etc.

Sometimes the fault lies in the USB cable)
  6. In ODIN, you will see several tabs, and you will have to select files respective to each tab. For example, click on CP and locate and select the CP file from the extracted firmware. In the same vein, click on AP and select the file with AP in the name. Similarly, add the BL file in the BL tab.
