iOS 11.4.1 Support?

[den-isehk08]

I have an iPhone 6S on iOS 11.4.1, i need to mount the filesystem to copy activation ticket as it does have a defective baseband and cannot activate if i restore it, but it seems doesn't have old version support, 11.4.1 is really old for this or it's fine?

Finally, to mount the filesystems, run mount_filesystems
/var is mounted to /mnt2 in the ssh session.
/private/preboot is mounted to /mnt6.
DO NOT RUN THIS IF THE DEVICE IS ON A REALLY OLD VERSION!!!!!!!

Once u boot ramdisk and copy activation ticket, u can restore the tickets to the latest ios it will work
