Over the weekend on a shoot my 2nd Solo gave me the "PREFLIGHT UPDATE" and I couldn't do anything with it. We had to move the shoot to Monday which didn't work out so well because of construction workers on job site.
I came to this forum and found some info about rebooting the firmware... BUT that info wasn't thourogh enough for me or not complete.
I wrote 3DR and got this response from Gio. I followed his instructions and it worked perfectly. This is a copy and paste of his email.
Hope this helps.
Hello, Steve.
Thank you for contacting 3DR Tech Support.
I'm really sorry to read you're having issues with the Solo.
Please, perform the following:
1- Power off the units and close the Solo app
2- Perform a factory reset to the Solo and controller, make sure the orange light underneath the Solo blinks faster during the reset process.

Factory Reset | 3DR - Drone & UAV Technology
3- Once the units are reset connect to the Sololink but do not open the Solo app
4- Make sure the Orange light underneath the Solo is blinking slowly, if so, please perform the following:
- Please, press the pair button for 1 sec and look at the controller screen for the "detected new Solo" message
Once you see the message "detected new Solo perform the following: Press A, then B and hold both buttons down. Once the Controller vibrates, you can let go. Within 20 seconds, the Controller will show “Solo Paired."
5- Once the Solo and controller are paired, please, confirm the orange light underneath the Solo is solid now
6- Open the Solo app >> settings >> updates >> start the update
7 Once the update process finishes, please, restart the Solo app
Please, leet me know your findings and if you have more questions.
Thank you for your cooperation and patience.
Best regards,
Gio Marin
