dji mini 1 drone flew very well but 2.4ghz was experiencing rc interferences. so after landing and switching to manual 5.8ghz to eliminate interferences, drone can no longer connect or even pair with controller. drone led running lights pairing indicator no longer working, computer access working but refreshing to latest firmware never solved problem (could be physical defect now - overheated). green flashing light on drone indicates its still looking for its last paired controller but cant connect with it anymore. it looks like there is a malfunction somewhere probably on an ic chip or the ic itself that handles pairing. now im suspecting something wrong with the atheros chip (handles transmission) or the ambarella ic (main processor and wifi transmision). looking forward for inputs from generous techie surgeons who have tried hot air rework on replacement of these components which have fixed problem is highly appreciated. or someone who have detected a culprit component contributing to the issue. thank you!
