It does not seem possible to load the new EU firmware after having the Mr Fux version installed. has the link on this thread been updated to allow for the new firmware does anybody know?
I had the same problem like you with the original download ment for the 2.15 versions. I could not get the 2.21 E installed for the camera. But I just managed to generate a bin file that does exactly that (two bin files for both directions A to E and E to A).
The explanation by the originator "Fux" on the first page is brilliant and easy to understand:
After renaming the TyphoonH_Ver2.21_E.bin to TyphoonH_Ver2.21_E.zip and unpacking it, renaming the included files.zzz to files.zip and unpacking it, you just have to rename the included file "cgo3+gb_3.2.13_LC2_E_firmware_30213.bin" to "cgo3+gb_3.2.14_LC2_E_firmware_30214.bin". (That is the actual trick!) Remember to change
both occurences of 3.2.13 to 3.2.14 in the filename (I forgot the first in the first try).
Generate a new MD5 checksum (free programs available on the net) from "files.zip" and paste this new checksum into the unpacked text file "FILE_MD5.txt" instead of the old existing checksum.
In the end you have to carefully re-zip the files (keep the original order, e.g. no extra folders), rename "files.zip" to "files.zzz" and "TyphoonH_Ver2.21_E.zip" to "TyphoonH_Ver2.21_E.bin", put this file on the SD card, put it in the CGO3+, run the setup via the ST16, restart your YTH and you will see the camera version 3.2.13 (E) on your settings display.
You will notice the camera binding will take instead of about 30 sec for the A-version about 60 sec for the E-Version, but the camera will also be recognized again by the WLAN of your mobile device! This way the CGO app can be used again which I am planning to do with a pure Wizard + CGO app constellation...
Big thanks again to "Fux" for providing this possibility and his brilliant explanation (that even I was able to follow)!
