Sorry, no help. DNS does not work.

1. Get root via hospitality mode
2. Use our experimental libFwDowngrade.so to unlock downgrade function

NB. Very risky procedure. If any failure- mainboard replacement only. But if ready, i can give further necessary info and file.

available libFwDowngrade.so does not support D series arm, however, i have one which does. This is only one difference between available libs - D series functionality was always there, but only in one version it is enabled... Indeed not fully tested. I tried it on mine D6500 and got older firmware recognized, went throughout downgrade process until final reboot and skipped, because of my customized rootfs does not have toggle tool, which was removed. Since DNS service had been working properly at that time we tested this lib, here was no need to perform final tests and no users with big balls to do it on their own responsibility. I`m sure fo 99,9 percent it works well, but i can`t swear it does not cause brick, because no one ran until the full TV reboot afterwards.
