I'm also interested in the method. I'm assuming the same method to Boost will also work to move the Sprint Galaxy SIII to a Sprint legacy plan like SERO. What I've found out so far:
1) QPST v2.7 Build 366 doesn't work on the Sprint GS3 except to add the diag comm port so that QXDM can see the port. You will not be able to use QPST to manipulate Profile 0 and Profile 1 to enable 3G.
2) QXDM v3.11.36 can be used for the repair. This will get you voice, SMS, 1xRTT data working.
3) To fix Profile 0 and Profile 1 to enable 3G, CDMA Tools DFS v184.108.40.206 looks to be very promising. Don't know what fields to fill out though.
I've seen ads in craigslist selling flashing services for the Galaxy S3 for use w/ Boost, so someone has already figured this out. Hopefully it won't be long before someone documents all the steps.
