Super frustrated with the Obi202 as of late. Suddenly was giving me the "Network Status, IP Address Not Available" error recording when dialing so I checked to see what was happening with the Obi202. The power light was flashing greeen, so noted that it is not connected to internet. Checked in router as I have the statis IP it is assigned sitting in DMZ. Noted in the router that multiple attacks had been made on this device in the last 2-3 days. From SSH brute force attacks, to exploits being executed via shell script like a Netcore Router backdoor access. Alarming to say the least but router blocked these attacks from "coming inside" In any case, figured the Obi202 was compromised. Checked that it did have latest firmware (3.2.2 (Build: 5921EX)) and then just did basic reset. Updated admin password (as was done before) and still could not get this device to get back online again. Router would assign it static IP, but no internet connection could be established. I had wanted to go ahead and try to re-flash the firmware with the same build since it is latest guessing that potentially the firmware may have been modified/corrupted, but am getting the whole "Firmware downgrading is prohibited" message. WTF!
In any case, trying to sort out what to do next, maybe there is a really hard reset that reverts to original firmware, but don't think that is case. Maybe something sneaky like TFTP to push firmware directly without trying to use Obi202 UI for the update/reinstall. Any ideas here?
Seems like I will not need to keep in DMZ anymore due to these attacks, had done this for best audio quality but also nervous about putting this potentially compromised device inside firewall/LAN and opening ports to it.
Any suggestions would be helpful as this device is now essentially a brick and useless.
