Regarding the serious issue of firmware flashing in 2015+Ranger/Everest, the same is true for a different computer. The results of using V4 devices are the same as those of V5 devices, and the problems with Win7, Win8, and Win10 systems still exist. We hope that the UCDS team can solve them. Thank you.

Thank you very much to the UCDS team for fixing the issue within 72 hours. The firmware and software can now be updated. We do not recommend updating old versions. I hope everyone can switch to UCDS V5. After using it for a few months, it feels much faster than V4.
