Odd Error Message Using Modem and RB912UAG

So I’ve tested my Sierra MC7700 with a Generic USB dongle and have made sure it can connect however when i use it with my RB912UAG-5HPnD? I get this odd message "Couldn’t Start, Configuration Running, please wait! (6)

I’ve reset all my settings to just test the modem and have even followed instruction on http://www.wirelessinfo.be/index.php/mikrotik/pages/3g

Any clues?

Thank you

I’am beginning to think that this issue has to do with the most recent RC build 6.28rc14 and the latest Sierra Firmware released for the MC7700 In December (Release13-SWI9200X_03.05.29.03)..

For some reason the Modem is getting stuck initiating so it locks the unit which is the reason for the error message!. I even tried my the Mini-PCi card in one of those USB adapters and used it in the USB port and got the same error!

UPDATE

*** The issue as I suspected is that the LATEST Sierra firmware Version SWI9200M_3.5-Release13-SWI9200X_03.05.29.03 released in December 2014 is the reason behind the modem getting stuck in the init stage. Version SWI9200X_03.05.20.03 which was a previous version released in November is working fine after I downgraded my modem. Not sure what changes have caused this latest firmware not to be compatible with routerboard!
