Solo emits loud warning sound after flop on side

[XevetS]

It resets the pixhawk, Hold it down and restart continue to hold down until you hear the startup tone, it will change to a different tune as it boots

Did you try UDP in mission planner?
Only other thing I can think of is you cracked a board or solder connection somewhere

This ^

There was a post from someone previously who mentioned 2 buttons for reset. Not many were aware. If I can locate the post I'll share. It's either here or in the FB group.

Solution to this week long exercise:

FB Solo Hackers (no idea why translating to ??? language) -> Kinakailangan ang Pagtiyak sa Seguridad
Can't factory reset solo?


Steps to fix:
(These are the total steps I did, may not have to replace sd images if can do factory reset and get proper wifi communications. I'm working in Fedora 25 Linux)

1. Join Solo Hackers FB Group
   
2. Grab new fresh images from Solo hackers FB group. See David's OneDrive images
   
3. Extract controller image
4. Burn images to fresh <8Gb micro-SDcards (expect to take a while)
   $ fdisk -l [to find correct SD card location]
   $ dd if=/location/of/the/file of=/dev/sdb [/dev/sdb on my machine, check]
5. Factory reset controller
6. Remove gimbal
7. Tear down your drone (if factory resets don't take or don't get wifi communications)
   Be super careful of moving main board too much and breaking accessory bay ribbon cable. Mine was entirely unsupported with goo and broke just looking at it. Because I don't need to run accessories in bay, no worries
8. Get small right-angle micro-usb cord
9. Plug into Pixhawk usb port [this by-passes the Solo card and stopped the warning scream, but more importantly allowed a complete boot]
   Look for black cube underside of main board - usb port on the side
10. Power up the Pixhawk with usb cable
11. Power up Solo after Pixhawk fully boots
12. Factory reset on drone with tooth-pick
13. Replace SD cards with new images
    Be careful to not force click sd card holder
    Scrape off factory glue
    Hot glue in new card
    
14. Do factory resets (continue with powering Pixhawk on its own before Solo)
    
15. Pair units
16. Using Tower or Mission Planner, reset SYSID_SW_MREV to 0, mine was 120
    $ sudo dnf install mono-devel
    $ git clone MissionPlanner
    set user rwx permissions for MP, otherwise will crash on start
    $ mono MissionPlanner.exe
17. Reboot everything w/o powering usb port on Pixhawk
18. Calibrate sensors
19. Reboot
20. Test w/o props
21. Go Fly!!!???!!!

The text Kinakailangan ang Pagtiyak sa Seguridad is Tagalog, Filipino, for 'making sure of security ' or something similar. My wife's Filipino. Lol

Does anyone have the pin connection schematic?, and does anybody know where to get ribbon cable and both male and female connectors? I feel an upgrade is needed for this ribbon.
