where can I download older versions of the firmware for CS 7.8? I can not find anywhere.

You can not downgrade the Crystalsky sorry ...

Hi FHUBONUS, there is no older firmware can be downloaded in our website, may I know what happened to your CrystalSky?

Hi DJI Mindy. After updating the CS 7.8 to the latest version, there is no option to choose HDMI so that the output is clear camera image. I have P4pro with CS and can not use for live broadcast. The same is true with the P4pro plus v2 model that I had and also there at the HDMi output is the same as the preview from the DJI GO 4 program. And I work live and now your equipment is useless to me. I spent a lot of money and you do nothing and the updates contain errors that you do not improve, you only reduce the possibilities of drone that you produce. Have you started to produce drones for children? You answer that your engineers are working on it and you can not see the results. I'm starting to hate DJI for doing this. Please, make a correction. I am waiting

DJI mindy, will you help?

after updating to 2.06.06, this option was not available in the previous version. How to restore it?

Hi FHUBONUS, sorry for the late response because I was off duty yesterday, we didn't receive other users reporting the same issue, may I know if you have tried to reset the CrystalSky into the factory default? If there is no luck, any chance to provide us a short video so that we can escalate to our engineers for further check? Thank you in advance.

You can download previous firmware version (2.6.30 2018/04/12) for CrystalSky from DJI HERE.
You have to copy download to microSD card for CrystalSky.
Then point CrystalSky built-in Updater to local copy.  Done by clicking (touching) 'Dots' in upper right hand corner from Updater menu.

DJI Mindy,

It seems Im having problems with new update as well. Flying a Inspire 1 pro- before update everything seemed good- I just got it a week ago (7.85 Ultra). when I updated to latest firmware my my onscreen video is extremely delayed and very jittery- no good! Also my way point feature is not working properly- nowhere to put gimbal in free mode (this option in waypoints no longer exist after update)- aircraft will fly way points but only in POV. Connected up my iPad pro and onscreen video is extremely stable- much better that the 900.00 monitor and waypoints work correctly.

HedgeTrimmer the link you sent FHUBONUS to restore older firmware did not work- it downloaded but would not unzip to anything I could put on micro SD card. Curious if FHUBONUS had any luck with firmware downgrade? Did you use a PC or Mac?

Hope that info helps.

This was a helpful thread. That Firmware link is for the CC7. I need to work on my CS5 also. I'm assuming the file I get here:      http://mydjiflight.dji.com/file/links/ZSA_pack_2630_20180412    is in fact the correct fils for the CS5.

I just replaced the "ZSB..." of the original link with "ZSA", which seems to be the normal naming scheme.

I have a mavic pro with a CS ultra . I had the latest version  2.06.06  on my CS which gave terrible latency and my controller disconnected mid flight causing the screen to freeze , I was 1 klm away from home. Very handy. This wasn't the first time.
I down loaded 2.6.30 from Hedgetrimmers link to SD then extracted all, followed the instructions to install it. No problem.
This has solved all my latency problem . I also flew up to 1.5 klms without any issues. Did they test this firmware  before they inflicted on us?
