I had a problem with my Obi 202 recently when it tried to auto update. It appeared to be bricked, but after a lot of searching, I was able to get it manually updated to OBi202-3-2-2-5859EX-198839. Afterwards, my Google Voice (Line 2) works fine, but I also have ObiBT (Bluetooth) on Line 1, and it has some problems. Anytime I try to call out on Line 1, it goes haywire. The Line 1 and Power LED both go out, I'll get a buzzing sound in the receiver, then both lines appear to got out, and finally the device resets. I can receive Bluetooth calls on Line 1 just fine. After some experimenting, I discovered I can select Line 2 (Google Voice), then dial **8 followed by the phone #, and it will place the call over Bluetooth. After reading these forum posts, I now believe it's a firmware problem, but I have questions.
1. Can I downgrade the firmware?
2. If so, what version do I need, and where can I get it?
3. What steps do I need to perform to prevent it from auto-updating?
I know someone has already posted an answer to #3, but I have no idea where those settings are located, so I need help locating them.
