Odin complete (write) operation failed is one of the many errors you might encounter while using the Odin tool to flash files on your Samsung device. If you are facing this issue, this guide has some solutions for you to apply and potentially resolve the problem.
If you ever want to customize your Samsung phone beyond what the built-in options allow, you need to flash a custom ROM using a tool called Odin. Odin is basically a firmware flashing tool for Samsung devices, and you can use it to flash many types of files on your phone. Occasionally, you would encounter various issues with this tool, one of which is Odin complete (write) operation failed.
If this error occurs, you will find that the data you wanted to write to your device did not get written. The whole procedure of flashing a custom file has failed and that’s what this error message is about. Luckily, there are solutions to this issue.
Before you go further down the guide, you might want to know the possible causes of the issue. If you can identify the cause, then perhaps you only need to follow one method to fix the issue.
As you can see for yourself in the error message, Odin talks about a write operation that has failed. This usually occurs when the tool cannot write your data to your device. It might be a permissions issue, or there might be something blocking the data from being flashed on your phone.
The second possible reason you have the aforementioned issue is that you are using an extremely old version of the Odin tool. In early versions, Odin had many issues which were then patched in newer updates.
Therefore, an obsolete version of Odin is often the cause of many issues.
Your firmware files are as much to be blamed for this error as the Odin tool. It might be that the firmware file you have downloaded is corrupt and so Odin is having trouble flashing it on your phone.
This inability to install firmware causes Odin to throw the aforementioned error message on the screen, and stop the flashing procedure altogether.
One possible reason is that you do not have the proper drivers installed on your computer. This causes your machine not to recognize your Samsung device, and this in return leads Odin to throw an error message.
There is not a single way to get around the said Odin issue. You need to follow the following methods until you find the method that actually works for you.
As you just learned, one of the reasons Odin displays that error message is that it cannot write data to your phone. There are actually a couple of options on your phone that need to be enabled if you want to perform certain actions on your phone. If you do not turn these options on, your phone will block new content from being added to it using tools like Odin.
These options are USB debugging and OEM unlock.
USB debugging allows your computer to interact with your Android device over an Android Debug Bridge (ADB) connection. It is a good idea to keep this option enabled when you are using your phone with your computer.
OEM unlock allows the bootloader on your phone to be unlocked. If you are flashing something that requires unlocking the bootloader, this option must be enabled.
Enabling both of these options is easy.
Step 1. Open the Settings app on your phone and tap System.
Step 2. Tap Developer options on the following screen.
Step 3. Enable both USB debugging as well as OEM unlock options.
It might be that the issue is not with Odin but is with the USB port on your computer. Many times, the USB port on your computer gets jammed and it will not work the way it is supposed to. This causes your Samsung phone not to be recognized by your computer, as your computer simply does not see the connected device.
One way to fix this issue is to change the USB port on your computer. Most computers have multiple ports and you simply need to unplug your phone’s cable from one port and plug it into another. This should likely fix the issue.
In order to recognize your Samsung device, your computer needs something called drivers. These drivers are specific to certain phones, and since you have a Samsung device, you need Samsung drivers installed on your computer. These help your computer to detect your device and then let you work with it from your machine.
If you are not sure you have the required drivers, you can download and install these drivers free of cost.
Step 1. Open a browser on your computer and head over to the Samsung drivers website.
Step 2. Download the driver’s package to your computer.
Step 3. Double-click the driver’s file and go through the installation wizard.
Step 4. Reboot your computer when the drivers are installed.
Odin should now detect your device without any issues.
Odin has many versions available for it. If you are currently running a really old build of the tool, it is time you get it updated to eliminate many issues attached to it. Updating the Odin version ensures you get newer features as well as all the bug-fixes that come with it.
The thing with Odin is that you cannot update it from within the app. You are going to have to get a newer version manually, and then use it to flash files on your phone.
Step 1. Head over to a site like Odin download to download Odin to your computer.
Step 2. Once you are on the site, click the button for the latest version of Odin to download the tool to your machine.
If you have questions related to Odin, we aim to answer them below.
If you are using the Odin mode for the first time, you probably want to know how long it takes for the Odin flash process to complete. This helps you find out whether Odin is working the way it should or it is taking longer than expected.
Usually, Odin should take about five to fifteen minutes to finish a flash process. This actually depends on the file that you are flashing, though. If you are installing something like a full firmware, this is going to take a bit longer.
On the other hand, if you are only installing a kernel or items like that, that should only take a couple of minutes to flash.
