Sorry, been extremely busy at work but I will post it tonight. I have all the screenshots done, I just need to do the actual writeup.
If the original method did not work then the RadioComm method won't either, though.
Have to head into work right now but I have a few ideas about this that may shed some light.
Finally got the time to write up the RadioComm method.
I will post here in the morning regarding the modem options and my understanding of the issue with Indian GSM carriers.
I can reupload the Telstra AU modem and the other options are all of the RAZR HD and Atrix HD modems are also compatible with the M and can be found in the XML.zips for those models and safely flashed in fastboot.
Check the thread - Aussie firmwares now available for JB...this may or may not help
