Flash Tool Baseband update

[nj777]

Hi,
I got ATT Xperi Ion with XperiaGPv2.1 but problem is I get garbled calls/digital noise and cant hear anyone.
Someone mentioned that flashing a ATT baseband might help. I did it through Flash Tool but seems my baseband wont change despite the fact that flashtool goes through the process 100%.
Please help what might be the problem?

the description for 'baseband version' in settings > about phone section doesn't seems to be attached to the actual baseband...meaning, when you flash a new firmware, that baseband description seems to follow it regardless of what you do with the actual baseband in flashtool...

about a month ago some one confirmed that, i'll try to find the thread...excluding a baseband during a flash of a different firmware DOES change things, as well as excluding everything but a baseband, which is what you did...and seems to be the best way to keep that garbled call thing at bay (someone found that it adds a UTC number in some hidden files)...but it won't change the description given in about phone...

thats all i know about it...i'm on JB 'h' .211 on an LT28at with ATT's latest baseband and haven't had the garbled call problem for over a month...it just trashed my gps, though, haha...
