I suck at this programing stuff. grrr. I know this should be clear cut, but cant seem to get either of these processes to work.
bootloader says v1.7ready... no firmware
but my version on radio says
vers: v. 3531-mike
DATE:08. 01. 2016

So, I think the latest version is on radio? but I cant update bootloader?
From the smariteparts site on updating firmware
The procedure for updating the unit's firmware is not intuitive, but it is simple. There are other methods, but following these steps should work:
Pinch your two horizontal trims inward while at the same time flipping the power switch on. This puts the 9Xtreme into bootloader mode. Don't worry about any message on the screen about "no firmware".
Now plug in the USB cable between your computer and your radio. If you already had it plugged in, then start over because order matters!
Wait up to a minute for your computer to recognize the new drive(s).
In eePskye, click the Burn menu and choose Flash Firmware to Tx. Choose the ersky9x9XT_rom.bin file you download from www.er9x.com. That should successfully update your 9Xtreme's firmware.
If you wish to update the firmware but do not want, or are unable, to perform the "pinch" method above then this is an alternative method but it uses different software and these steps assume you're using Windows:
Download and install STMicro's DfuSe software from the bottom of this linked page. Run the application.
In the software there is a box labeled, "Available DFU Devices" and inside that box should be nothing.
Plug the USB cable into the 9Xtreme and "STM Device in DFU Mode" should appear in the aforementioned box.
Right-click and save the following 9Xtreme (Rev 218) dfu file to your computer: LINK
In the section labelled "Upload Action" there is a button marked "Choose...". Select the file you downloaded in the previous step and choose "Upgrade". There will be a warning about not being able to confirm if this is the correct file while in DFU mode, which you'll have to ignore to continue.
