Prior to this effort my drone had stock controller firmware and stock copter firmware. I took it for a flight last night, everything worked perfectly fine, no issues. Camera worked, flew for about 10-15 minutes.

I decided to install Open Solo 4 via Solex: Install via Solex App · OpenSolo/OpenSolo Wiki

I printed out the instructions, carefully read through once before I read through a second and third time. With the printed instructions I was checking the boxes as I went.

When I got to step 3.

Install Controller Package: From the firmware updates menu in Solex, tap the Open Solo 4-dev Clean Install (Controller)package that you previously downloaded.
  • Press install. Press install again when prompted again to confirm. This is your last chance to change your mind.
  • Be patient while numerous large files are extracted and scripts execute. Do not push buttons, exit the app, mess with the Solo, etc. Let it do its thing. Until it says it has completed.
  • Solex will tell you when the whole process is complete.
  • DO NOT REBOOT THE CONTROLLER YET! You must do the install for both the controller and the copter before rebooting anything. Once Solex tells you the install is complete, leave the controller and move on to the copter install.
The installation never finished. It just hung, the controller disconnected from the Solo drone, now all it says is waiting for solo on the controller. Solex doesn't see the drone anymore. I've tried to pair the drone with the controller again...no luck. Eventually the controller just turned off.

I have no idea what to do now.

Please help.

PS, I can connect to the controller, but the controller can't find the vehicle. Also, solex doesn't display the firmware update menu when it's not connected to the vehicle. Should I pair another controller and install the copter firmware (I have two more controllers) I just have no idea what to do and how to get this thing flying again. A factory reset doesn't work on the controller it wont factory reset like my other controllers will.

Update...

I did a factory reset on the drone and pulled the battery out of the controller and did a factory reset. This got me back to square one. I am able to get the controller to pair with the drone however I get a message to launch the 3DR app to calibrate before first flight and Solex will connect to wifi but not the vehicle.

I may try and install arducopter firmware, copter IMX and controller IMX via SSH instead of via solex and see where that gets me.

How do you brick the controller or drone so I know what NOT to do.

Thanks,

Bryan

I wish I could help but I know nothing of the aftermarket apps. I have considered installing them just as you are doing but I have read many instances of occurrences just like you are having. I fear I am not savvy enough in the ways of software gremlins to figure my way out of them. Please keep updating this thread to let us know what happens.
Good luck,

Suggestion only based on what I've read about Solex installs. The original reset firmware does not get over-ridden. So you probably can do the reset on the controller only and try to start over from sq. one. Maybe you got a wifi interruption on your first go around that hung it. Also there's a blurb in the instructions about no beep, no indicate when update finishes so wait at least 6 minutes ... I've done a couple of these and wait 10 minutes as the units seem to do nothing .. but really are updating. The controller resets ITSELF and restarts during all this, just leave it waaaaay alone for a long time.. best of luck, you have a real good chance here.

In December 2021, to fly my 3DR Solo after a long time, I was forced to buy the Solex app and update the firmware, in my case because I turned them off too quickly I had to disarm the drone and the controller to install the Open Solo 4 on their respective SD cards. Then pressing the reset button under the drone for 3 seconds and A + B of the controller pairing both of them, but after several attempts it did not recognize the drone on my Sony cell phone, then i tried a Huawei tablet and neither.

Finally worked with a Xiaomi MIUI 9 cell phone and I was able to fly my 3DR Solo again. You could also try with more modern cell phones.

My problem now is the batteries.

i completed the factory reset then used solex to do firmware just like the information given step instructions, i was unable to complete the calibrations and something popped up (peram 25%) So i went back to square one, and attempted to reset controller and drone again, controller reset perfectly but drone, when you power up holding the PAIR, it goes into the fast orange light flashing and then after a bit it goes to a slow flashing and nothing happening after 30 minutes. just flashing.. tried pairing drone to controller and pair completed, but not found on the solex app. Vehicle not found. PS, i dont know if it has any bearing, but i have several solo drones, and was able to complete the first one and get into the air no problem, but the second one is giving me issues.
