FW 700 Aircraft Locked. Help!!!


Jul 5, 2017
Hi pilots,
I got a Mavic half month ago and just flew for twice.
And now DJI locked my drone just because I didn't upgrade to 900 firmware. I can't believe they did this, INCREDIBLE!!!
I will never upgrade because:
1) I don't want to be controlled.
2) 700 firmware is good enough for me I think.
3) There still are many problems in the higher firmware, it's not stable enough.
4) They just added too many features which I don't care in higher version of DJI GO 4 and it becomes larger and larger.
I tried lots of ways to unlock it but all failed. I tried to downgrade my DJI GO 4 to 4.0.3 on both iOS and Android, no go. I tried to use DJI GO 4 off line, no go. I tried to use Litchi instead, no go.
I thought they locked the aircraft by app, but I was wrong. Even I powered the drone only it still showed the long red light which means that it was abnormal and I cannot start the motors. So, I tried to do factory reset the drone with DJI Assistant 2 v1.1.0 but it seems that doesn't work.

Now I think there will be a way to figure it out:
fully factory reset the drone (maybe and controller).
But how? Could anyone can help me to unlock my poor drone? Or have any thoughts about it?

Please save me...

BTW, I am so curious that no drones of yours have been locked? Or they just lock drones in China? But how did they know??? By IP address or GPS? or firmware?

Just do the upgrade...eventually DJI is going to force everyone to do it. I used the most recent FW & SW on ALL my DJI devices with no issues

Relax, my upgrades are all good.
At a wild guess I think my thinking is consistent with 90%+ of users.
Firmware has no issues I've come across. I'm on 900.
Any issues I've found on both my Mavics has always been a ribbon cable fault.
It seems that most of you guys has upgraded and have no issues. um, I will think about it...
