MRST Dongle Actually we need to learn more about MRST technology, it needs a lot of things for me to learn and to have more experience, I hope the team will guide the SC5 and SC6 functions. What does PRL mean? The one with the additional flasing function is still not supported for the ota file community, I don't see it anywhere. If we want to develop strongly, we also need to have an additional tool integrated into the tool, a file support tool like UFI, it's too VIP... I hope it will be stronger in the future.
