Jetson Xavier AGX can not USB after flash Jetpack 4.6.4

Hi , I’m trying to reflash my Jetson Xavier AGX(32G) but after flash, I can not use mouse and key board anymore. But when I’m flash with Jetpack 5 version , can use usb again.
First, I use sdk to flash but it show:
The target is in a bad state
The Jetson target is in a bad state and cannot be flashed. Please manually put the target into recovery mode and then retry flashing.
So i flash with cmd :
sudo ./ jetson-xavier mmcblk0p1
I also try another config like jetson-xavier-maxn or jetson-agx-xavier-devkit but won’t help.
Because my project request Ubuntu 18.04 so can not change to Jetpack 5. Please tell me what info you need to fix this. Thank you

If it’s working on JetPack5 then we will not fix it on JetPack 4.
