Then the advanced functionality usually involves unlocking/re-enabling the device’s features that have been disabled by the OEM. In this regard, recently I was trying to bring back the WiFi toggle on my Android 12 device which Google has removed from the stock OS. For that, I just needed to execute a single line of command and the task would have been complete. However, it proved to be easier said than done. Every time I executed the ADB command, it gave out the device offline error.
But in all of this, there was one interesting thing that I noticed- the command prompt was still able to identify the device ID upon executing the adb devices command. So my first course of action was that there might be something wrong with the device. So I re-enabled USB debugging/switched to a different cable and tried other such tweaks, but was still getting the same ADB Device Offline error. Just to tinker a little bit, I tried executing another command to boot my device to Fastboot Mode. But still got the same error.
So this made me sure that the issue is with the PC itself. To double-check, I switched over to a different Android device and again got this error, but this time I noticed something interesting- it was still displaying the same device ID as what was shown for my first device. This isn’t possible since two devices cannot have the same ID. Well, the weirdest part was the fact that even when no device was connected it still showed the device ID. So all this made perfect sense now- the ADB window wasn’t even checking the status of the device in the first place. Whatever cached values were saved, it just displayed that- irrespective of the device connected. Now that I got hold of the reason behind this issue, the fix was relatively easy to execute. And yes, it worked out on the first try itself. So without further ado, let’s check out the steps to fix the ADB device offline error. Follow along.
How to Fix ADB Device Offline Error
Before starting off, there are a couple of things to keep in mind. First off, it is recommended to use the official USB cable that came with your device. Along with that, you should also consider using the USB 2.0 Port instead of the 3.0 port as the latter isn’t known to work well in the ADB and Fastboot environment. Once you have checked marked both these requirements, you may then proceed ahead with the below steps to fix the ADB device offline error. That’s it.
