Firmware update for 20x series
jentzd:
Hello,
I have a 202 that is updated to 5859EX, but a specific setting is not working for me.
I would like roll back to 5794EX. I have the old fw file (and several other old fw files) but logging in to the web interface will not let me roll back. It says instead
Firmware Update Failed
Firmware package checksum error
I know the file is good, used on other devices. Same error with other "good" fw files too.
Any way to force it back?? Did I essentially brick this device (for me ) by going to 5859EX? I do not use google voice.

GPz1100:
Once you you accepted the new firmware there is no downgrading.
For those that don't want to fall into this trap, use the modded firmware which allows downgrading and offers some additional features - unsanctioned of course.

Due to perceived "issues" introduced by 3rd parties, the firmwares now attempt to validate the authenticity of the loads on the devices. It is a little unclear if one will be able to roll forward/backward between all validated firmwares in the future, but you cannot go back to a version before the validation was enabled (for what should be obvious reasons).
You are better off opening a case with obihai/polycom to get your setting issue resolved (whatever that is) and prepare to go forward.

So what IS the most current and desired firmware following the recent Google Voice carnage? I just bought a new Obi200 and it's displaying 3.2.2 (Build: 5897EX) on the device status page. I see no reference anywhere of this particular version. At any rate, I got the new device up and running with Google Voice and Callcentric E911/CNAME subscription. Initially everything seems OK and I can make and receive calls, which wasn't happening with my Obi100.

I upgraded my Obi200 firmware yesterday to 3.2.2 (Build: 5897EX), and cannot get Google Voice to ring or call. I see that I am supposed to have the new option of OBiTALK Device on my Google Voice Legacy Settings page, but it is not there.
This explains why I cannot make or receive calls, because everything else from OBI panel shows connected and online.
I have reset (both hard and soft) the Obi200, and followed the various instructions from prior posts, but nothing has helped.
Anyone have any ideas on what else I should try?
Thanks in advance.
