Did I brick my remote (URC3680)

Post by 120240VAC60HZ »

Well did I?

I was trying to add codes to my remote and I accidentally plugged my JP1 cable in backwards!

Now I get no signs of life no lights when buttons are pressed as well as no IR signals blasted either and RMIR does not see the remote at all I tried the "JP2Dumper" tool and when I try to use it I only get the "Bad address" or "106Sig block doesn't contain 6 digits"

So I must have corrupted something so is this a lost cause or is their a way to fix this?

Thanks

I thought only JP1.3 remotes were susceptible to being bricked by plugging the cable the wrong way round. Yours is JP1.4 but they share the same processor, S3F80, so it is possible you have done that, but I wouldn't give up on it yet. Have you tried completely rebooting it by removing the batteries, pressing any button to discharge any remaining capacitance, then reinserting the batteries?

I would expect plugging the cable the wrong way round would cause a hardware fault, not software corruption, so the fact that you get a response at at all is a good sign, I think.

So what (if anything) can I try next?

Are you using Windows? If so, you can test whether the remote is capable of entering communication mode.

To do this test, you need RealTerm and this document by Tommy Tyler: Identifying the Processor and Signature of an Unknown Flash Remote. It is an old document and not applicable in full to a JP1.4 remote, but the part about testing if a remote enters and exits communication mode does apply. That is up to the line "Try taking the remote into and out of serial comm mode several times to convince yourself it's really working."

This is a very basic test. If it fails, then I can't think of anything else, since at present the remote is completely unresponsive.
