Being open-source in nature, Android OS offers an insane level of customization. You can redesign your phone and add new features by installing a new custom ROM. Moreover, to take the customization onto a new level, you can root your phone to overclock the processor speed or add advanced features. In between the process, you’ll need to use the command prompt to perform various operations where many people get stuck. The most common error message is “Waiting for Device”, which you must fix to reach the next step. In this article, we’ll use various methods to fix the “waiting for device” error in ADB or fastboot commands.
Be it flashing custom ROMs via custom recoveries such as TWRP or rooting the device via Magisk, you’ll have to use ADB commands. And if you’re getting the waiting for device error, don’t worry; there are proven ways to fix it. The error message appears when your PC fails to detect your smartphone connected through Android Debug Bridge (ADB). This could happen due to various regions. Some common reasons include not using USB 2.0 ports, USB Debugging not being turned on, and driver issues. If you know the problem, navigate to the particular section; otherwise, go through each solution step-by-step to fix the issue.
How to Fix Waiting for Device Error in ADB or Fastboot Commands
After trying out every solution, run the command where you get the waiting for device error to check if the problem is fixed. If not, move on to the next solution and see which one does the trick for you.
Solution 1: Use USB 2.0 Ports
It might sound strange to you but the USB 3.0 ports, as reported by many users, is the real culprit when performing ADB commands. Leave other users, my IdeaPad 5 which has two USB 3.0 ports also throws the same error. So, if your PC has a USB 2.0 port, use that while performing ADB commands. In my case, there’s no USB 2.0 port on my laptop, so I ended up purchasing a USB 2.0 hub and the problem got rid of that error message.
My computer is on Linux (Ubuntu 22.04), it should even be easier (as Android is a cousin)
But everything is made for Windows :(
My issue is that it stays stuck on fastboot flash recovery twrp.img
I tried so many things ; not the cable though, I would have to buy one, trying other solutions but all I find is for Windows :/
