[Google TV General] ali387:
I followed the above steps and it seems to have worked. I am seeing a peculiar behavior on my device which is when I try to use 'adb shell' command. The 'adb shell' simply disconnects after few seconds.

Has anyone heard or run into issue like this? At the end of this message I have added the entire terminal session that I went through to flash this modified vendoe_boot image. As always appreciate any input from the community.

Example problem scenario:

[root@fireiso ~]# adb devices
List of devices attached
GUSA1317010114 device

[root@fireiso ~]# adb shell
YOC:/ $ ls
acct data_mirror metadata sdcard
apex debug_ramdisk mnt second_stage_resources
bin dev odm storage
bugreports etc odm_dlkm sys
cache init oem system
config init.environ.rc postinstall system_ext
d linkerconfig proc vendor
data lost+found product vendor_dlkm
YOC:/ $ su
YOC:/ # ls
acct data_mirror metadata sdcard
apex debug_ramdisk mnt second_stage_resources
bin dev odm storage
bugreports etc odm_dlkm sys
cache init oem system
config init.environ.rc postinstall system_ext
d linkerconfig proc vendor
data lost+found product vendor_dlkm
YOC:/ # cd syst[root@fireiso ~]# em

While I was trying cd into system folder my adb shell closes. This happens all the time now. I would run 'adb shell' and after few seconds 'adb shell' session closes and I am back to my terminal prompt.

Another example:

[root@fireiso ~]# adb shell
YOC:/ $ su
YOC:/ # [root@fireiso ~]#

Below is the terminal session capture of the steps I followed:

[root@fireiso ~]# adb devices

GUSA1317010114 device

[root@fireiso ~]# adb install ./Magisk-v26.1.apk
