Hi!
I have a Speedybee 60A 4in1 BLS ESC.
Bo be able to have bidirectional DShot600 I wanted to flash Bluejay with esc-configuator.com
ESC4 and ESC3 succesfully flashed.
ESC1 flashing progress bar stopped at about 98% but after rebooting the drone, it was working.
ESC2 flashing progress bar stopped at 70-80% (I was waiting for 5 minutes for something to happen, but it just stuck there 
) And after rebooting the drone, esc-configurator.com is unable to connect to ESC2.
After some googling I found, this happened to other guys and there’s an online tool to re-flash to ESC via C2 interface.
There’s another tutorial, that is using BLHeliSuite to re-flash the bricked ESC: https://www.youtube.com/watch?v=uys8h7_GxYU
Is this the only way, of are there other methods to “resurrect” my bricked ESC?
Thank you!
