[linhmieu2]

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??

@linhmieu2 are you editing the defconfig file manually? You should try using make menuconfig for that.

There's a postmarketOS port for your device, have you tried looking at their flashing configs for your device?

[linhmieu2]

@idonthatevests i tested with that , configs still = n

[idonthatevests]

@linhmieu2 Have you tried changing string constants, such as CONFIG_LOCALVERSION just to confirm that the kernel has been flashed correctly? You need to unlock your device's boot loader to flash modified images.

@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
