It should be possible to fix this but nobody seems to know. I tried to contact tp support, but only received general answers that it is bricked and I have to buy a new one. It is not technically bricked, because a bricked router can not be operable at all. It is still possible to login and change firmware to openwrt og other tp version, but it seems that it is not possible to flash full firmware with tftp. There should be a way to transfer the filesystem from the router firmware file to the router somehow.

Same problem here. I need to turn on roaming but I can't access the Page. Got MR4600 v2 with latest firmware. Any solution?

I found a temporary solution to the problem (LTE Dial Up Settings page blank):

- Turn off the router
- Put out the sim card, start the router and wait for Wifi
- The settings are accessible now. Make your configurations.
- The "Network Mode" selection was disabled, but it gets enabled when I push the sim card back in and reload the page
- After a while, with the sim card in, the modem connects, no need to reboot. As soon it's connected, the menu entry is blank again.

what also seemed to help is to turn on the Sim-Pincode, so the modem can't connect automatically.

I still hope there's a bugfix soon, this is definitely no fun.
