Me successfully flashed my "TM" DIR-850L to FW:2.11SG firmware. Cause I wanted to get rid of the @Unifi.
Thank you DLINK, and good riddance "@Unifi" SSID.
(Anyway me not using Unifi, so that's fine)

Hi, you can follow the link here:

https://www.dlink.com.sg/starhubs/dir-850l/

Then if yours is Hardware B, download the 2nd link. I flashed it and it has been working without the @unifi ssid.

Apparently there is a newer International firmware version.
I haven't tried but ived used this SG version for weeks so far no issue.

Aiks. I have no issue here. I tried on my Yoodo, no problem.

Alternatively you can either use a VPN , or use your handphone hotspot and connect to your PC.
Because even me and socratesman have no issues loading the DLINK Page.

This is really odd.

Sorry to reply to your post after like 2 years later.
I faced this same issue. Flashed my firmware to the newer 2.11SG (Non UNIFI firmware), was working fine until then yesterday, did a hard reset , and I really couldnt login with the correct admin password

So after googling, I found out that need to go into Recovery Mode:
So here is how to do it:

1) Off your router.
2) Use a paper clip or small screwdriver, press and hold the Reset button first .
3) Power on while holding on the reset button.
4) Use a lan cable, set to static IP (any IP address) in Windows LAN first.
5) Goto the router page and upload the original firmware (mine was originally TM, so I tried back TM firmware) . Old version also can.
6) After flashing the firmware, then restart the router. It will work again

Original source: https://openwrt.org/docs/guide-user/install...nk_recovery_gui

Update on this:
Yesterday all a sudden the DHCP server, stop giving out IP address to a few of Android devices.
Windows is fine though.

So what happens is that I did a factory reset, thinking the DHCP might had corrupted or something.

Thats where more hell breaks loose.
Whereby not only it default back to the WIFI name, but primarily, as wayne experienced, cant even login even with the correct admin password.
Even no matter how you hard reset or even do "recovery mode" (different than upload recovery firmware), it will not budge.
Spent several hours finding and fixing the problem.

Thats where I had no choice but to do firmware recovery back to its original TM DLINK Firmware. Then only can login back. Can refer back to my earlier posting how I did it.

Few things I've learned:
1) Somehow non original firmware other than TM's firmware cause it to misbehave at the login part.
2) If you backup your settings in other versions of firmware, and restore, it will also screw up. This is what happened when this morning I tried to restore back my settings, which was from 2.11SG firmware, then again "admin password failure" happened again.
3) Yes you can upgrade the firmware later, but if shit happens, you have to flash back the original firmware. Using only LAN cable.

Short answer yes. This is the extract from DLINK

I havent tried the latest firmware, but even the Aus 2.1 onwards has removed TR069 and has QOS Bandwidth limit feature

But as I mentioned in my earlier post, after update latest Intl' firmware do not perform any factory reset.
