MangOH Red/WP7607-1/AirVantage install

Hello,

I got a MangOH Red board with WP7607-1 module. I flashed the device with swiflash (first the user partition with -r and after I burned the latest spk file with swiflash -m wp76xx -i WP76xx_Release9_GENERIC_SPK.spk. I can connect to AirVantage server and I can send data, but installing application through AirVantage fails or hangs.

Could you please help me?
