I have now purchased 4 Skydroid T10. Use them for boats. And in general I am very pleased with the hardware, the performance and the device helper app that is linked in the user manual by QR code.
The app has, amongst many things, a built in ability to check if the remote or the receiver has a new firmware available. And ability to perform firmware upgrade. All very nice.
I have now upgraded two of my remotes and one of my receivers with a version stated as 5.3 (2021.4.8). And that was obviously something I should never have done, even though the app clearly stated it was needed/recommended. Because afterwards the remote can no longer connect to the receiver. Not pair with other receivers either. Pairing process is so simple, just put the receiver in pairing mode and turn remote on. With 5.3 firmware the remote loose the pairing to the current receiver. Can no longer pair with it afterwards. And also cannot pair with other Skydroid receivers. I have a few, and it is simply not possible. So the 5m3 version bricks, or at least render useless, an otherwise fine product.
Now. The device helper app has a handy feature. And ability to also pick a firmware file locally in addition to autodownload the most recent. Great idea. If only previous firmware was made available. So far I have not found any source. So it is not possible.
I have two friend using the same remote. They have both tried to contact Skydroid to ask for older firmware that hopefully can revert the gear back into a working state. And generally speaking there is no response at all. I bricked my second transmitter today. And if I had called my friends first they would have told me to stay away from any update. Sadly too late.
Does anyone know of a source of previous firmware for Skydroid? T10 obviously my focus. There are some really lengthy Skydroid discussions here with representatives advocating their products. If you read this, please help. Because this situation is nothing short of bad. The equipment is not cheap either, so I think Skydroid’s customers deserves answers on support requests. And old firmware versions cannot be too much to ask for. Not to forget that bad firmware should be removed from download to avoid further bad experiences for the customers down the road…
