flash to original firmware

[jiri-jirus]

it is unclear in Flashing Guide whether it is possible to flash back orignal FlySky firmware, and how to do that.

thanks.

It's explained under Alternatively flash using STM32 CubeProgrammer:

"First, make a backup of your firmware. Fill in: Address: 0x08000000 Size: 0x20000, then press Read, then Save As..."

The "EdgeTX buddy webpage" didn't work for me. It said something like "Invalid device".

[jiri-jirus]

so this will restore even the original bootloader?

If you have a backup created before flashing then everything will return to the original.

If anyone needs the stock firmware, here you go: https://mega.nz/file/6nwUgaKD#VjrGvq5Uw_kmVUQHWH4AbpVrYWwM2e2SmHvVOzWwAqM
Hardware version is V1.0. Of course, it's better if you make your own backup, as I can't guarantee this will work.

Hey @skycraftmike ,
Could you share maybe a google drive link for the firmware file? Also just curious if the STM32cube worked with the APM32 chip. As i had the same and I had to use Qmktoolkit to flash.

[skycraftmike]

did send you email but it says file to big then i just send you the firmware.bin file ST32 does not see my radio i used the dfu-util to flash opentx on it much better than standard firmware more stuff to set and hack was or are looking for a way to pus SD card reader on the radio like i ddi with my 9X radio will search and let know If i get something

[skycraftmike]

oh forgot to tell you my operating system is linux ubuntu 22 and the STM32cube runs on it but does not pick up my radio
