Please go to your BSP folder. It is on your host machine with default path ~/nvidia. Run below command to configure the user account/password as nvidia/nvidia. > sudo ./l4t\_create\_default\_user.sh -u nvidia -p nvidia And reflash your board agian. > **[NVIDIA Jetson Hacks | RidgeRun](https://developer.ridgerun.com/wiki/index.php/NVIDIA_Jetson_Hacks)** > > This wiki page has the details about NVIDIA Jetson Hacks. This will bypass the stuck in serial console and let it boot up. We can check the desktop issue after this one gets done. If you don’t understand what we are doing, then it is the explanation: In the first boot after each fresh reflash, it requires user to configure the user account and password to proceed the boot up, if you don’t do it, then the boot will get stuck. For now, we just bypass this configuration and check why the desktop GUI cannot show up on your device. ---
