to 11.2 and back to 11.1-U6: wich bootloader?

[tmueko]

I upgraded to 11.2 and the system hangs while mounting zfs:FreeNAS-boot
I booted in 11.1-U6 and zfs find some checksum error on one of the usb sticks. I replaced da0 with new da2.
I used to write the bootloader after resilver using grub-install --modules="zfs part_gpt" /dev/daN

Because of moving to 11.2, I don't have a grub bootloader any more: how to i write it to da2?
I deferes from da1 and da0 (i tested using dd if=/dev/da1 bs=512 count=1 | hexdump)

I'll try
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 da2
...

Were you able to resolve this?

I used the one I write but didn't tested yet.
