I’m getting three LED blinks when trying to connect to the cloud.
I could connect my core to the cloud before and then I tried setting up a local cloud server and connecting the core to it. I could successfully fire up the server though when I was trying to connect the core to the local cloud, it didn’t get connected.(Apparently it was a handshake problem which I found out later when checking the server logs.) Then I tried to connect it again to the spark cloud and from that point onwards I’m getting three LED blinks in between cyan and green flashes. (3 red blinks->6 seconds of cyan flashes->1 second of green flashes->6 seconds of cyan flashes->3 red blinks)
When I read up in the forum it says that it’s a memory mangement fault. How can i fix it? I tried the factory reset a few times, ran keys doctor, flashed the 33000 patch but couldn’t get it to work yet.
I think the blink counting only works if your Core is flashing the SOS pattern first.
I was seeing the same thing as you on my core the other day (after it being packed away for several months), and I think resetting the public cloud key was what finally got it working again for me. Try the instructions from the first post here:
This may or may-not be what finally solved my problem on Friday. I tried so many different things, I don’t remember now. But if you still don’t have luck, maybe I can look at my computer at home tonight and see what else I can recall from my browser history.

Make sure your core is in DFU mode (blinking yellow), and that your computer is online.

Can you please explain me the last point? I’m sorry but I’m pretty new to the spark community.
Although when I did spark keys server cloud_public.der and tried spark setup again, now it gives one second cyan flash and half a second red flash in a loop.
I followed your steps. Now it keeps flashing cyan in a loop with half a second red flashes. It’s difficult to identify any pattern as to when the red flashes are occurring.
Yes, I ran both of the commands without any problem.
I just tried connecting the core to the using the mobile app. It says that We found a core and let’s name it. But the core doesn’t shout any rainbows.
Will it help if I do a factory reset, flash the c33000 patch, tinder, then issue the two commands to fix the public keys and then try it? I’m sure whatever the problem I was facing earlier is not there now since the flashing pattern has changed.
Okay the flashing sequence is a bit weird now. Moment ago it was only flashing cyan, then cyan was on for like two or three seconds(no flashes no blinks), then 1 second white, then again 1 second cyans and half a second reds
