This system never was 4.* (began from 5.0-DP2). [..] I predict, you will need serial console access. Chances are very high, that something even minor goes wrong, such that you cannot login to the box using ssh at some stage. You might still be able to complete the downgrade if you would have console access. People, who can hit the reset button, can also connect two serial ports with a null modem cable. So you should convince somebody to do that. Set up the serial console port on the machine should be feasable remotely without great risks. For the 4.x System you should also provide a kernel with serial console enabled. You chance of success will be much better, as I would see it.
