I downloaded unlocked firmware from asbokid at
https://huaweihg612hacking.wordpress.com/about/ and unlocked my HG 612.
I started to look around, and as my router is at 192.168.1.1 I changed the HG 612 to 192,168.1.148.
Then I turned off QoS and the firewall and all was well.
I experimented further and enabled LAN 2, and found I could plug in my router to access the internet through either Lan 1 or Lan 2.
Interesting, but I could no longer access the GUI.
I tried reloading the unlocked firmware, but although I could access 192.168.1.1 during the upload, once the HG 612 re-booted, I could not access the page at 192.168.1.1, nor the page at 192.168.1.148.
Then I reloaded the original (locked) firmware, followed by the unlocked firmware, but to no effect.
The HG 612 works fine, but I'm locked out of the GUI.
Any suggestions?
Should I try the Howlingwolf firmware at

I'm reluctant to muck about too much further in case I brick the HG 612.
