How to Update Official Samsung Firmware with ODIN

26 mayo, 2021

Waiting for your device to get the latest version of Android -with few exceptions- may be maddening. First you must cross your fingers so that the manufacturer decides to update it, then wait for the update to be ready and, finally, for it to be extended to your region and operator.

If you know that your device already has a new version but you are tired of hitting search for updates and tell you that you already have the latest version of the system, there is still something you can do: update firmware by yourself. This, of course, as long as your terminal is not tied to a specific network (that is, it is free).

This is how Samsung makes money: the secret is on the IPHONE

1. Find and download the firmware

There are several web pages that automatically collect firmware published by Samsung on its servers, as is the case with Sammobile. These firmware are official, without any type of modification and therefore once installed it will continue to appear as official firmware, without root and other stories. It’s like getting it through Kies.

The database is huge and includes all the Samsung device models ever and to be. Now, you need to make sure of the exact model of your device so as not to end up downloading firmware for a similar model. For example, a Galaxy A5 is distributed in more than 20 different models. If you have good eyesight, the easiest way to check is to read the tiny letter on the back of the mobile.

The same information is available in the system, in Settings – About device, in the Model number section. It is important that you check the exact model, since the difference between one and the other can be as subtle as an additional letter or zero.

Model

Once you have it located, go to the firmware download section in Sammobile or another firmwares page of your choice and look for your model. The search engine is sometimes a bit treacherous, so make sure after searching that the results are indeed for the model you wanted.

The results list can be a bit overwhelming, since all the firmware known for years are included for all the regions in which that particular model is distributed. As you are probably interested in the most modern version of Android, which has not yet reached you through official channels, it is most likely that in this case the options are fewer.

Firmware

Do not worry too much about the countries, since if your mobile is free, technically you should be able to install the firmware of any country. Now, you should consider that each country may have a slightly different system configuration, including the number of Available languages on the system (you could always use this trick to use another one), the apps pre-installed and regional versions of Samsung Pay that they would not go in your country.

The pre-installed apps can be very different from region to region, as those in China are totally different from those in Russia. For all this, it is recommended that you choose and download the firmware closest to you: If you are in Spain, firmwares from other European countries will be better for you than, for example, the Vietnamese version, which could do without Spanish.

Once you have selected it, download it to your PC. It will take a while, since today’s firmware takes about 2 GB of space and Sammobile allows you to download at a reduced speed unless you pay (registration can be gratuitous, you don’t need to pay).

2. Unzip it into a folder

The firmware is downloaded in ZIP files that you must open and decompress somewhere on your hard drive. The specific folder does not matter, since you can later find its location wherever it is.

3. Download and open ODIN

The main tool to update your Samsung from Windows that we will use is ODIN. You may download Odin 3.12.17 from here. Unzip it somewhere on your PC and then open Odin.exe, or open it directly from the ZIP, as you prefer.

4. Restart the mobile in Download mode

You already have everything ready. Although updating Android should be painless, it never hurts make backup copies and manually check if there is something on the device that we are especially afraid of losing. If so, better put it in a safe place before, and you never know.

When everything is safe, turn off the phone and then turn it on in download mode. To achieve this, most, if not all, Samsung devices require you to turn on your phone while pressing the button. Home, the power on and the volume down.

When you do this, a warning is displayed on the screen indicating how bad it is to modify the operating system and the problems it can cause you. You must press the button to increase the volume to show that you are satisfied and decide to continue.

At this time a screen will appear on your device that says Downloading, and will wait for orders.

5. Connect the cable to the PC

Connect the device to the PC using a USB cable that is legit. There are a lot of bad cables out there, and you wouldn’t want them to be disconnected in the middle leaving your phone stumped. It is also important that you have a sufficient amount of drums, for example more than half.

6. Load the firmware

In Odin, one of the boxes under ID: COM should light up blue indicating that it detects the connected mobile or tablet. If so, press the button AP to choose the firmware that you unzipped somewhere on your hard drive.

The first time you do it, the system will start check file integrity with checking the MD5 hash. Don’t despair if it seems to get stuck for a minute.

7. Check the options

Odin’s standard configuration is sufficient to install the firmware, but it never hurts to do a manual check for the flies. Go to Odin’s options tab and verify that the only thing that is activated is Auto Reboot and F. Reset Time. The most important thing is that Re-Partition is not marked.

8. Let’s flash!

It is done. Take a deep breath and press the Start button. Fear not, everything will be fine. Progress will be shown both in Odin (a green progress bar with some text) and on the device, with a progress bar below the Android stick.

The process will take a couple of minutes, and then the device will will restart automatically, since we had left the Auto Reboot option checked. The first time you start up with a new version of Android takes a long time, so be patient.

If we are talking about Marshmallow and not Nougat, there will be an additional process of “optimizing” applications once the system has started. This process can easily take ten minutes, depending on how many applications you have installed.
