Mass Storage not working pine64-pinephoneA64

[realroot2185]

When pressing volume up I see the blue led of mass storage but after it turns red.
I erased eMMC and reinstalled tow-boot.

Version: pine64-pinephoneA64-2022.07-006.

Can I flash the shared.disk-image.img without breaking the partition table?
I've made it using gdisk https://nixos.wiki/wiki/NixOS_on_ARM/Allwinner_GPT_Installation.

OS: Artix Linux aarch64 
Host: Pine64 PinePhone (1.2) 
Kernel: 6.6.6-1-danctnix 

I have u-boot package from Danctnix with this fix to allow booting from external TF card.
But it wasn't flashed with dd.

That NixOS's wiki command breaks partition table and you don't need to make any hole.
I tried it with the hole.

I used dd to write zeros and reinstalled tow-boot again.
Now it works.

How can I remove u-boot if I have GPT?

I see that the Tow-Boot's wiki command won't work for GPT.

$ sudo dd if=/dev/zero of=/dev/[DEVICE] bs=8k seek=1 count=4
Some distributions target UEFI boot, and use GPT. Issuing this command will break the partition table.

u-boot was dded using:

sudo dd if=${TMPMOUNT}/boot/u-boot-sunxi-with-spl-${DEVICE}-552.bin of=${DISK_IMAGE} bs=128k seek=1 oflag=sync
