I want to change the MSL of my Prevail. I've changed the MSL on other phones. It can be done in CDMA WS. Connect to the phone. Read. Send the original MSL of the phone. Phone is unlocked. The next step is the problem. On other phones I replace the original MSL with the one I want it changed to and Write it to the phone. After a few seconds the MSL is changed. With the Prevail though the MSL doesn't get changed. Anyone got any ideas?
