Unable to Pair Up Aircraft and Remote Controller due to incompatible firmware versions

[kunajk]

My drone had firmware version 1.9.8. I decided to roll back the firmware because after the update my drone stopped taking off. No matter which method I used(autostart, or controller) the propellers would launch for a second or two, then shut down without any error message. I've read on the forum that recalibration of the compass and firmaware rollback may help. Since recalibration didn't help, I rollback firmware to version 1.8.2. Unfortunatly I did this with the controller disconnected and as the result the controller software didn't update. As the result I can't pair my simple controller with the aircraft anymore.

I have the following questions:
1. Can I upgrade(rollback) Simple Remote Control firmware without connected aircraft?
2. Does anyone have a 1.9.8 firmware so I can update the drone and re-pair it with the controller?

All best!

Fun fact: V1.9.8 Release Notes just disappeared from the page. Yesterday it was there.

Because before I rollbacked the 1.9.8 firmware to bthe 1.8.5 with the controller turned off, I belive this made the firmware versions no longer match. According to the firmware table(Autel Robotics Product Firmware Version Sharing Table - Updated on 20240805) my controller has Transmit-RC V1.0.7.28, and my Aircraft has Transmit-RC V1.0.7.3.

I believe that to solve the problem I should:
1. upgrade the firmware version of the aircraft body by SD card to 1.9.8 to make them belong to the same firmware version;
2. then to make the aircraft compatible with the IOS app I should downgrade the firmware with the controller enabled so it will make the firmware install on both the aircraft body and the remote control

But how can I do that without 1.9.8 firmware image? I wrote to support but they want me to send the drone...

I have the same problem. Controller can't connect to the aircraft. Did you solve it ?

Just wanted to chime in... after I installed v1.8.5, my controller and the drone fail to pair. So if anyone has a link to v1.9.8 it would be appreciated

Was your controller on during the upgrade process?

I have the latest version of firmware FW V1.9.10 and the remote does not connect to the nano either.

I also have this issue. Got Nano+ yesterday, updated to 1.8.5 just fine and all was well save for the prompts to update to 1.9.10 which consistently failed to install through the app.

Got 1.9.10 from Autel this morning, tried to update via SD card and now I can't pair the drone to the controller, I just get aircraft disconnected...

Sadly the release notes say 1.9.10 can't be rolledback from

So I think I updated to 1.9.10 and now it "seems" to connect, but the RC signal strength goes from full to disconnected in what appears to be random way. It will disconnect within a minute every time- how soon seems random. It "seems" to connect in that I receive camera input and can move the gimbal, and it gives the ready to fly green prompt. But it will not launch and I have yet to see the sky app identify what firmware it is running (it gives N/A firmware). Anyone with similar experience?
