"I recently was trying to reset a friend's phone (Samsung SM-J727R4), and it was being stubborn, doing 2fa with the former user's phone number. I decided to take it to my computer and have a go at it using adb. After running the adb reboot bootloader, the device rebooted into the bootloader, but it just froze there. I tried unplugging the battery, and once I had plugged it back in, it was booting into recovery mode with a bluish screen saying 'No command'".

The "no command" error on Android devices can be frustrating, especially when it appears unexpectedly during startup or recovery mode. This error typically indicates that the device is unable to execute a command or access necessary system files. While it may seem daunting, the issue is often resolvable with a few troubleshooting steps. In this guide, we'll explore the reasons behind the "no command" error and provide actionable solutions to fix it.
The "no command" error typically appears on the Android Recovery Mode screen, and it can occur for several reasons, such as:
Here are six effective methods to resolve the "no command" error and get your Android back to normal.
This is the first thing to do, and it's an approach that's frequently suggested by the community on forums. Try re-entering recovery mode, as it can help you fix all issues on your device. Here are the steps:
Step 1. Power off your device completely.
Step 2. Press and hold the "Volume Up" + "Power" buttons together.
Step 3. Release the "Power" button once the Android logo appears, but keep holding the "Volume Up" button.
Step 4. If the device enters Recovery Mode without the no command screen, you're good to go.
When we encounter issues with our electronic devices, the first thing that comes to mind is to reboot the device. When you reboot your phone, its operating system will be forcibly shut down and then restarted. This helps fix many minor errors that may be causing the problems, and there's no harm in trying this method. However, a forced reboot may not be applicable to all issues, and the success rate of fixing an "Android no command" error with this method can be low. You just need to press and hold the "Power" button for 10-15 seconds until the device restarts.
Residual and junk system files on Android devices can accumulate over time from app installations, updates, and general usage of the device, potentially leading to errors such as "no command". If you're unable to boot your system, you can use the recovery mode on your Android device to wipe the cache partition. This process helps remove these unnecessary files and often resolves various issues, including the "no command" error.
Step 1. Reboot into Recovery Mode.
Step 2. Select "Wipe cache partition" using the "Volume" buttons.
Step 3. Confirm the action, and wait for it to complete. After the cache is wiped, restart your device.
How do I bypass the no command screen? You can also perform a factory reset on your phone. This will erase all existing data on your device and restore it to its factory settings, which may potentially fix the "Android no command" issue. However, please back up your Android phone before resetting it to factory settings.
Step 1. Boot into Recovery Mode.
Step 2. Use the "Volume" buttons to select "wipe data/factory reset".
Step 3. Confirm the action and wait for the process to finish.
Step 4. Restart the device, and it should boot up without the no command error.
If none of the above methods work, it may be time to flash the official firmware:
Step 1. Download the correct ROM for your device model from the manufacturer's website.
Step 2. Use tools like Odin (for Samsung) or Fastboot to flash the ROM.
Step 3. Follow the instructions carefully, as flashing a ROM incorrectly can permanently damage your device.
