I am trying to get into recovery mode to reinstall ubuntu on my TX2. However, I have tried to enter recovery mode many times using methods I have seen on the internet, but I cannot enter it and ubuntu boots. When I run lsusb, it does not show up as “NvidiaCorp”. The procedure is as follows. (1) …

If even the method in “part2.mp4” is not able to make your board into recovery mode, Please reboot your jetson TX2, open a terminal on the HDMI monitor, and use command sudo reboot forced-recovery This is software method to put the board into recovery mode.

Thanks for the reply. I tried the method you suggested, but I couldn’t get into the recovery board and ubuntu booted.

What do you mean ubuntu booted? So the board still boots into OS?

Yes, the ubuntu installed on TX2 boots normally. However, I need to reinstall ubuntu and I am about to enter recovery mode. I saw on an internet site that ubuntu will not boot when I enter recovery mode, but I can check it from another computer with ubuntu by using “lsusb”. So, if I can see ubunt…

Hi, Looks like what you are doing in “part2.mp4” is already correct. When the board is in recovery mode, no OS is running so it is normal that HDMI won’t show anything.

Always start with REC pin instead of RST or power BTN.
