Either SRS computer can sense the seat belt sensor is fried, you fried SRS computer or you caused temporary SRS error, which will not clear by itself. I would start with disconnecting battery for few minutes and see if that will clear the error code. If the voltage on the meter was low, that should be the only problem. Otherwise play stupid and take it to the dealer, even code resetting requires Toyota scan tool which you don't have. But even disconnecting battery may not clear the code, even if there is no other problem at all. I remember there was some very convoluted way to reset SRS on my old Honda Accord without any tools, but I don't remember seeing anything in the TCH service manual, either way if you have one double check it. You should be able to drive the car with SRS light on, but I don't think any airbag will deploy in case of accident.
Now, if you want to drive without seat belt, fasten the seat belt and seat on it, just get the metal insert, disconnect the "noise maker", reprogram the computer to inhibit the sound alarm or keep on driving, it will go away after about 30 seconds or so, your approach was probably the most difficult of them all. Good luck.
