In this guide, we will show you the steps to fix the Operation not allowed: java.lang.SecurityException error while executing the ADB Shell command. The possibilities stand endless when it comes to stepping into the ADB and Fastboot domains. While Fastboot commands mostly come in handy when your device’s bootloader is unlocked or is rooted, that isn’t the case with ADB as you could extract the maximum potential of these commands in a stock environment as well.
Moreover, with the addition of adb shell commands, you could even carry out some administrative-level tasks on your non-rooted device. However, as of late, using these commands is proving to be a tough nut to crack. Numerous users have voiced their concern that whenever they execute an ADB shell command, they instead get greeted with the Operation not allowed: java.lang.SecurityException error.
What is interesting to note is the fact that the PC could identify the device in the ADB Mode, as upon executing the adb devices command, the CMD list out the serial number of the device. Moreover, even the adb shell command works well and good, as it will list out the device codename. However, any command that you execute after that will result in the aforementioned error. With that said, there does exist a couple of nifty workarounds that shall help you resolve this bug. So without further ado, let’s check them out.
