Hello , im porting ubuntu touch for device: gta7litewif but it get black screen

i seen get some messages like in this device:
pid.codes Test PID has been connected.
wired connection has been connected.
and 0afe has been connected.

how to fix that?

(SOLVED)i forgoted to flash vbmeta and now config works

@idonthatevests i already to unlock bootloader , i tryed change CONFIG_LOCALVERSION to "UBports-tab7lite" but shell still get result ís 4.19.191-25600224-abT220XXU1CVL7

@idonthatevests i tested with that , configs still = n

Hello , im porting ubuntu touch but it not booting

i seen some message like :
pid.codes Test PID has been connected.
wired connection has been connected.
and 0afe has been connected.

then , i ask ChatGpt for ask my bugs and it says :
" Native Ubuntu Touch / Sailfish / Mer NOT POSSIBLE on this device because:
Samsung locks the kernel boot
Android Kernel:
No SYSVIPC
No devtmpfs
Not systemd-ready
No vendor_boot
Cannot boot Halium initramfs
️ Modifying the kernel config has no practical effect"

also i cant enable CONFIG_DEVTMPFS to y

$ grep -n "CONFIG_DEVTMPFS" workdir/downloads/android_kernel_samsung_mt6765/arch/ar
m64/configs/gta7litewifi_defconfig (EDITED DEFCONFIG TO Y)
1355:CONFIG_DEVTMPFS=y
1357:CONFIG_DEVTMPFS_MOUNT=y

$ adb shell "zcat /proc/config.gz | grep DEVTMPFS"(BUT AFTER FLASH , still not set)
CONFIG_DEVTMPFS is not set

check kernel but kernel still kernel stock rom)
$ adb shell uname -r
4.19.191-25600224-abT220XXU1CVL7

is impossible to porting??

Trả lời: Build Ubuntu Touch error : Halium initrd Failed to boot
I fixed this problem . sorrry, is my mistake comand
method :
./prepare-fake-ota.sh out/device_gta7litewifi_usrmerge.tar.xz ota
./system-image-from-ota.sh ota/ubuntu_command images
adb push images/rootfs /data/ubuntu.img
and next its success to run kernel but cant mount my rootfs (i see it at dmesg log)
i think i need more time to make this tablet work correct with ubuntu touch
here ís log in dmesg :
