Linux4Tegra R24 Boot Problem

I am not really sure where to ask this question. My question is regarding Linux4Tegra R24 on Jetson TX1 for the Nvidia Shield TV 2015. I was able to boot into Linux4Tegra on a USB flash drive on my Nvidia Shield TV 2015 before I updated my Nvidia Shield TV 2015 to Android Pie 9.0. Now the fastboot boot image does not work for the Linux4Tegra USB installation. Is there anyway to make the original USB boot img to work with the new Android Pie firmware on the Nvidia Shield TV 2015?

I assume its just the fact that the Android firmware changed around the partition mount locations. For example, the USB mount could have been changed from SDA1 to SDA2. And the boot image just needs to be recreated to address this location change.

If it helps, these are the partitions on my Nvidia Shield TV 2015:

Hi ferrari7rider,

Here is the forum to support Jertson platform, we have no much experience with Shield TV, sorry for that.
