Nvidia-l4t-multimedia auto updating system from R36.4.4 to R36.4.7

Hi,
I have a custom boot logo and other boot settings done and properly working for the Jetson Orin NX 16GB Module with R36.4.4 (Jetpack 6.2.1 rev1)
but the moment I install the nvidia-l4t-multimedia manually in the jetson and reboot, The system auto updating the whole l4t version to the R36.4.7. Which completely remove my custom boot logo and other settings. And i try to see the document of the release for the R36.4.7, but I couldnot find any.
And the one more major issue is, After this updated to R36.4.7, i cant flash the jetson easily by USB and by sudo reboot forced-recovery inside the jetson. I manually need to connect the jumper wire and then flash it. And then also from the sdk manager the flash fails at between , but the NX module flashes. but the logs shows the following.

  1. Tell me what is the best way to avoid auto update the l4t version , but i have to install nvidia-l4t-multimedia.
  2. And After multiple reflashing the R36.4.4(Jetpack 6.2.1 rev 1), still that Jetson is not able to finish the flashing smoothly, How to solve this issue.

Thanks in advance.

HI,

Please run below commands on Orin NX side

sudo apt-mark hold 'nvidia-l4t-*'
sudo apt install nvidia-l4t-multimedia

Please make sure the device whether in recovery mode and use lsusb to check

Thanks
