We were discussing this in another forum last night: Was what will now forever be known as the 4-F: The Famous Firmware "Foul"-up of twenty-Fifteen intentionally sent out by DJI to cover something else up? First of all, I'm not making a statement, I'm asking a question...the same question that apparently a LOT of other P3 owners are asking. (>55% by this esteemed forum) -Why else would DJI (...and their designated trolls) be so obtuse about admitting, much less rectifying, the firmware problem? -Were only certain production runs of the P3 targeted for firmware "foul"-ups? That's to say, did the firmware updates have imbedded check-sums to target specific (possibly defective) serial numbers of production runs to identify or mask other problems like shell cracks, cold-solder joints, etc. after they were already shipped? -Why is it taking so long? The entire operating program could have been totally re-written 5 times by now, much less time to be repaired. -What's so hard about simply making a statement, "This is cutting edge technology and someone dropped the ball. We have our best people working on it right now and we'll have a rollback in the meantime until we can sort this out..." -Is issuing a firmware rollback that difficult? DJI owes their (>$1,000.00 a pop) customers an answer. Click "Support" if you agree.
