We have updated our Sprint unlock algo using "Sprint" tab in XTC 2 Tool.
There is no need to download any updates, just use Sprint tab as always if you have previously had any problems with Sprint unlocking.
This should apply to all Sprint phones.
P.S. Valid MEID is required in order to request correct SPC from Sprint database! If you have changed your MEID – please revert back to original for the unlock process to work.
Please report your results!
