Ok so I have been looking for the Metro PCS R350 DLL to no avail. I did Manage to get the r350 fully flashed to Cricket though.

Unfortunately in order to do this I have lost the tri-band functionality of the freeform for now so no AWS market.

To do this you will need the R351 DLL and BIN file along with SPST (samsung pst).

Put the freeform into emergency boot (9+Power) And fire up SPST and go to the SW button on the left.

Select EMERGENCY from the dropdown menu and select the R351 bin and away you go.

When it is done @ 3 minutes later just go into settings and edit away. If you need an mmc file let me know and I will provide you with one.

This I believe is one of the Hardest Sammy DLL's it has not been my pleasure to try and find.
