Steps To Install Official Android 10 Stock ROM (One UI) On Galaxy A12 Using the Odin app

1. First you need to download and install the Samsung USB drivers.

2. Now we need to enable the developer options, USB debugging and perform the OEM unlock on your Galaxy A12.

To enable “Developer Options” on your Galaxy Smartphone goto Settings>About phone>Software Information, and tap on the “Build number” 10 times until you get a message that you are a “developer.”. Now you will see an additional menu entry in the “Settings” menu called “Developer Options” as shown below. 

Once you have enabled the “Developer Options” tap on it and you will see a similar screen as shown below (These are from One UI 2.0, if your UI version is something else slight difference maybe there).

Now tap on “OEM unlocking” and “USB debugging” to enable it. If  you get a popup warning, tap enable if you would like to proceed.

In some cases after “OEM unlocking” is enabled you may need to unlock the “Bootloader” also. Please try the below tutorial if you get a failed message in Odin;

You may need to login/create a free account to download the files from the 3rd party website. Also make sure that your phones bootloader is not locked by any carrier, if so please unlock it first before proceeding with the firmware installation.

4. Now download the Odin app from the below link or download the latest version of Odin;

When the download has finished please extrat the file to your PC desktop and open the “Odin..xxx.exe” file.

5. In the next step you need to enter your Galaxy A12 into the “download mode“.

For that first you need to switch of your Galaxy A12. Now switch it back on and when you see the “Samsung” logo on the screen press and hold “Volume Down + Volume Up” and connect your mobile with your PC using a USB data cable.

Now when you get the above warning message on your phone screen press “Vol Up” button to enter into the “Download Mode“. You may also try the below video tutorial if you have any confusion which uses a different method. The demo phone used here is M30s.

In the next step select the extracted firmware files (done in step-3) corresponding to each buttons in the odin app. For example click on button “CP” and select the extracted firmware file which starts with “CP“. Same way click on “AP” and and select the extracted firmware file which starts with “AP“. Similarly, add BL file in the BL button.

If you want to factory reset while you install stock firmware select the file which starts with “CSC” file for the CSC button, otherwise, load the “HOME_CSC” instead.

Make sure F.Reset.Time and Auto Reboot option are the only ones checked in the Odin’s “Options” tab.

If you don’t want the previous data on your phone please skip the last button on Odin which is “UMS” or “USERDATA“.

7. Once everything is done as said above, click the “Start” button in the Odin app and wait for the flashing process to get completed. Finally when it’s done your Galaxy A12 will reboot and you will get a “Pass” message from the Odin app.
