I really need help ! I am only a few months into this hobby and I love flying. I turned on my tx and forgot to put the antenna on so I powered it back off in a hurry and I got a sd card warning. I turned off the transmitter to see if the sd card was ok but now it lost all memory of my models and won’t bind when trying to reset it to a quad. I emailed jumper and never got a response. I contacted the hobby shop where I purchased this and they can’t help either telling me to email the company. I’m lost and confused. Please help if possible. Thank you.

Let us look at this step by step.

First question, how long did you keep the radio powered up without an antenna? A transmitter can burn fairly quickly if powered without an antenna. If you have burned the transmitter module then you can still use your radio with external modules and so the radio is not completely junk at this point.

What sdcard warning were you receiving? Did you update the sdcard contents or update the OpenTX firmware on the radio without updating the sdcard contents?

With regards to loosing the binding to all your quads, what exactly happens when you try to bind? Are you powering up the quad with the correct method to put your receiver on the quad into bind mode? It might be the case that you have burned up your transmitter module which is why it is unable to bind.

We need those extra details to understand your problem and advise you better in this regard.
