On XDA, GSMArena, and repair forums, the consensus is overwhelmingly positive for v3.0 RC5, with caveats: qualcomm tool v3.0 rc5

Users have reported occasional instability when switching between Firehose and DIAG modes on the same USB instance. The development team has acknowledged these race conditions and plans to address them in the gold master. Nevertheless, for advanced users who value new features over absolute stability, RC5 is the most capable Qualcomm tool to date. | Error Message | Likely Cause | Solution
