Welcome back to another post about the Samsung Galaxy. In this post, we will demonstrate how you can flash firmware or stock ROM on your device. There are a lot of reasons why people like you and me want to flash their Samsung devices. The most common reason is due to a network issue, country lock issue, software issue, IMEI issue, or a problem with the latest software update.

In our case, it was a Carrier lock issue. It means that our device was unable to make any phone calls. You can read more about this here.

Before we jump into the steps on how you can flash your Samsung device, it is necessary that you follow certain things.

Backup Device Data

When flashing a stock ROM on a Samsung or any other Android device, the device’s data gets formatted. So it is necessary that we perform a full data backup of everything that is necessary. To backup the device’s data, we can utilize the features provided by Google Drive and Samsung Cloud Storage.

To perform a backup of photos, we suggest using Google Photos, and to perform a backup of notes, calendars, contacts, and applications, we suggest using Samsung’s in-built cloud storage feature.

Similarly, we can backup important documents and files from our internal storage to another device, such as a PC. In our case, we backup the important files to our PC. Simply copy important files and documents into a PC folder.

Because we are familiar with custom recovery like TWRP and Orangefox, we are glad to let you know that you can backup everything on your Android device, including applications, application data, calendar, Operating System, Contacts, Google Accounts, Call logs, messages, etc., using these custom recovery. We can literally backup everything, including the system, except internal storage files. Read more about it on our blog.

Precautions Before Flashing

The device also needs battery power during its first reboot. Make sure that the battery is charged to more than 30%.
  • USB Cable: Make sure you are well equipped with a working USB cable so that while flashing the firmware there is no connection issue between the PC and Samsung device, because if it does have some issues, there is a 95% chance that your device will be soft-brick in the process.
  • Ensure Complete Backup: Make sure that the backup which you have started is complete. You can also check it on the cloud storage to ensure backup are completed.
