Solved Esc error code and motor not working

I have a cheap chinese 30a esc, I have been looking around the internet for 2 hours and i have not found a fix. It has been recently in the rain, dried it, worked perfectly fine then 30 mins later it just decides to not work. Not a voltage issue, 12 volts exactly, Not a throttle error or something because when i go full power it goes into a ''special'' thing im not sure of like 6 musical tones then beeps like morse code and i dont understand anything!! (that tells me it can read the full power signal) Anyways, It goes 1-2-3, proceeds to beep 10 times then 1 long beeeep and then the motor does not spin AT ALL! Please help i have been searching 2 hours all over the internet and i dont know whats happening! And if your nice maybe you could help me a bit understand the musical tones :) After the musical tone at full power, if i keep it there it goes beep then beep beep and so on and so fourth, Then some other patterns that im not sure of.. I only care abt the esc working and not programming it or anything, What could i possibly do? Its been 5 hours since the rain and not 100% OF THE ENTIRE MOISTURE Has been evaporated so could that be the case?! I dont know, Please help! I'm new! :) (note! Before this issue happened, when i was outside just about to take it in while it was still raining, when i wanted to start from 0, it was like brbrbrbr and going super low rpm maybe trying to sync somehow? And then home i lifted the car in the air and same issue happened! Even more.. But when i dried it, KINDA turned back to normal? I would be really sad if i fried the esc somehow as i dont have much money)

What is the modal of ESC? So its was doing the jerky motor thing, like it was was out of timing? I find that usually is because of one of the wires of your motor or ESC being questionable....What motor are you running?

Model of esc is unknown haha, its just a chinese esc, It wasnt jerky motor thing, it was moving only one direction and very slow rpm almost like a stepper motor, and it would do also a weird electrical sound in that time, A 1400kv no name motor tho, next day now, the same issue happens so it isnt because of the moisture.. I hope nothing is fried. Oh and that br br thing was at lower throttle, but before the rain it had no issues at lower throttle, Moisture in the coils or smth?! I dont knoww

It was doing that before the jerky motor thing, i was okay with it atleast trying to spin, now its not even giving 1 singular degree of turn! :(

No black spots, just copper. The motor was working but its the esc giving me problems. The motor spins a tiny bit when doing the beeps so it isnt fried but after the esc ''initializes'' the throttle does not work

Hmm, okay....Just a motor can jerk jerk jerk kind of turn if its fried...Is there anyway you could get us a quick clip of a video and a pic of the esc?

I think i need to open up my esc to inspect more.. Everything works just not the motor spinning, again, what does 1-2-3 then 10 beeps then 1 long beep mean? i always had beeep.. BEEEEP! Before now it does 10 beeps after the 1-2-3..

Have you possibly reversed your throttle channel inside you transmitter? That can cause it to go into "programing mode" which will act like that...

No, havent, tried on a servo tester and on my transmitter, if i keep it at over 1% throttle it goes into ''programming mode''

I would open up my esc then isolate it back with e tape just to see if smth got burned.. you tell me! I'm new to the hobby and i just know how to work with my hands, not much about electronics lol
