Phone always boot to fastboot after flash custom kernel from twrp - Xiaomi Poco F1 Questions & Answers

Hi
My phone is always boot to fastboot mode after flash custom kernel
Start with I build a custom kernel from github[dot]com/MiCode/Xiaomi_Kernel_OpenSource/tree/dipper-p-oss
the build process was done without error and got Image.gz-dtb
so I pack the Image.gz-dtb with original boot.img that I take from official firmware
then I make a .zip that can be install by using the TWRP
the script to install is just mounting partition, copy some file to system and dd my boot.img to /dev/block/..../by-name/boot
I use twrp-3.2.3-2 from official site and flash it to the phone to recovery partition
then I try reboot the phone to normal mode and TWRP mode for couple of time, everthing just fine
Then the issue begin after I flash my own custom kernel using TWRP, flashing was done without any error
but after I try to reboot the phone, it goes back to fastboot mode. Then I try to reboot to recovery by hold power and volume up, fastboot mode again
I try hold every possible combination key and it still back to fastboot mode
Ok, then I think it time to flash the whole firmware again and I did flash it using MiFlashTool
the flashing was done without error
but it keep getting back to fastboot mode after reboot
I've try just boot the TWRP from fastboot and it fail with below error
FAILED (remote: 'Failed to load/authenticate boot image: 00000050')
If there any way to fix this?
on some phone like Moto they have like oem command to set to which mode to boot in, they have command like
fastboot oem fb_mode_clear
to set it boot mode to normal
Is there something like this in poco?
# dd path of flashing script
DEV_BOOT_PATH="/dev/block/platform/$(cd /dev/block/platform && find -name boot)"
print "auto default dev_boot_path: $DEV_BOOT_PATH"
if [ -b "$DEV_BOOT_PATH" ]; then
print "* using auto default dev_boot_path: $DEV_BOOT_PATH"
elif [ -b "/dev/block/platform/msm_sdcc.1/by-name/boot" ]; then
print "* using msm kernel boot path"
DEV_BOOT_PATH="/dev/block/platform/msm_sdcc.1/by-name/boot"
elif [ -b "/dev/block/platform/7824900.sdhci/by-name/boot" ]; then
print "* using sgrand kernel boot path"
DEV_BOOT_PATH="/dev/block/platform/7824900.sdhci/by-name/boot"
else
print "* using exynos s6 (SM-G9200) kernel boot path"
DEV_BOOT_PATH="/dev/block/platform/15570000.ufs/by-name/BOOT"
fi
-------------------- EDIT --------------------
Just found the reason of brick,
there are empty dtbo.img file that has been copy to /dev/block/platform/soc/1d84000.ufshc/by-name/boot (in my understanding, it didn't exist in this phone)
any suggestion?
