Hi.
I have an PS59D6900 (Plasma) running the latest firmware 1025. I tried to the downgrade using the DNS 46.101.161.175 but it says no upgrade is available. I did a tcpdump of the queries from TV <-> 46.101.161.175, you can find it here:
https://pastebin.com/AtX2aQ5g
Note: the DUID is XTCIT2MEERLB6
Any chance my model will get supported soon?
If not, any chance where I can download the 1090 firmware and install it manually via USB?
Thanks in advance and best regards

T-MST5DEUC is supported. Try to reset OTN, reboot TV. Use LAN cable, not wireless connection. Also do not use proxy servers.
After all, check for firmware online once again. Logs show nothing bad, just procedure interrruption.

pls send me your DUID and/or your external IP you were connecting from to pm. I`ll check logs. But are you sure that you have already done:
reset OTN, reboot TV. Use LAN cable, not wireless connection. Also do not use proxy servers.

Yes, i`ve got everything. I just do not have good news atm. Server is online, but seems, we do have undefined issue. No downgrade is possible until we find what`s wrong. Apologize.
