Hi, I am trying to build a custom kernel for the Samsung Galaxy A03 (model: SM-A035F), with has the Unisoc T606 chipset, currently running Android 13. However I can not get the kernel to boot by unpack and repack boot.img or using Anykernel3 zip. I have read some tutorials on this site for Unisoc devices, but I think because this phone was built by Samsung so it is much different. 
What the phone can do:
-Unlock bootloader the Samsung way, it mean it doesn't require any token as the tuts for Unisoc on Hovatek  
-Flash Magisk by patching boot.img and flash using Odin
-Flash Gsi with STOCK vbmeta, most Gsi work.
-Flash a blank vbmeta, but only the vbmeta I attached 
.img
blank_vbmeta.img
Size: 256 bytes / Downloads: 1

-Flash Twrp, but I think nothing is working, at least it boot okay.
What it can not do:
-Boot a custom kernel, a repacked boot.img exactly.
-It doesn't have fastboot by default but we can enable it using this for gsi and other stuff flashing.
I kinda feel hopeless in this, I already asked this on Stack Overflow and even Samsung Dev Forum but got no answers. I hope someone could lead me the way for this, thank you very much.

Hay idk if you get your answer or not but I can tell you one thing most of the unisoc device's use AVB 2.1 so empty vbmeta doesn't work, it means you have to make a new vbmeta image with necessary private and public keys and use that keys to sign your repacked boot.img by doing this you can boot your custom kernel.

Boot image signing is necessary.
