Hey man, I did your procedure, it worked. The blank screen error was solved and SAFE screen came. But once I connect the ESC back to the normal port, it shows version and keeps blinking, nothing else is working.
Bro I ordered new kk 2.1.5 board from flyrobo but while programming the screen text went off I tried your method but its not working please tell me what to do. and it cost me 4887 rs
Found even easier method. Just connect the 4th esc normally. Connect the Green wire from flash pins (as in video ) to positive+ of Buzzer. That's it Done.
Thanks for the suggestions, but while i incenses the THR, only the fourth motor is rotation, others are only making a beep sound.. my question is, can u suggest some that, that with this process, i could easily achieve the success for rotating all the four motors, in order to process the quad-copter operations.
sir mere flight controller ke resiver setting me aileron no signal dikha rah hai aur yaw, rudder, etc signal dikha rah hai kya aap mujhe baata sakate hai kya problem
@@coolplus1830 Brother first of all thank you for seeing my problem...... Let me explain u.... I got the parts yesterday i tested my kk flight controller with a single esc just to know how it works and it worked flawlessly. But when i soldered all the esc's together on the frame and when I connected the signal pins on the kk and connected the battery then for some duration the buzzer was(still only the lcd backlight was lit up and not the display) working but after some time even the buzzers too stopped and there was no display yet only the backlight. So yesterday night i gave up and guessed to wait until tomorrow then today when i thought of working on it and connected the battery the buzzers, display worked!! But just for 2 secs aftet which it faded away...... Do note the following : 1. all things are soldered perfectly on the frame 2. I didn't tested all the esc one by one with the controller only i tried with one with which i thought other 3 will also work and i soldered them. 3.I haven't charged the battery since i got it because my charger broke. Please i request you to reply me as soon as possible because i have a presentation nearby and i gladly thank you for all your support.... Pls help!! Regards
@@adityapruthi01 bro in that case there are 2 things possible. Firstly charge your lipo and then try it out if it doesn't work reflash it with the latest firmware. For flashing you need a usbasp cable available for 250 ₹ online.
And thank God.... I just got lucky it worked... Actually my charger was faluty and it wasn't charging my lipo which the new one did and now its working like a charm...... But bro pls help me with another thing...... 1) I've calibrated all things, used the correct apparatus but when i move the throttle above 50% it (with the propellers on Nd just testing, tied it up to the base) all apparatus just reboots and it stops...... Else if i don't have the proppelors on only the motors then if i give it 100% throttle too it doesn't stalls... 2)Even when sometimes it handels 100% throttle it does not lifts off......it even does not leave the ground even.... 3)well today I found out that my lipo voltage alarm was showing the votage of my cell 1 and 3 and not 2nd......is that possible???. And is it the reson that to maybe why my quad is not getting full voltage from my battery and it stops after half throttle Nd i can't get my quad to fly????..... Bro please reply ASAP coz to be honest i dont have really anyone to discuss this topic to and i want it to get ready before 9th of sept...... Pls help bro Thanks...... Pls keep in mind my apparatus 1000 kv motors 30 amp esc Kk 2.1.5 F450 frame 3300 mah 25c lipo 1045 proppelors
Then in that that case there is no problem with the board. Check if this thing happens with another transmitter. I think that there's some problem with the transmitter
I tried using this method on the controller but it did not work after removing the wires. What could be the problem?
Thanks for the suggestion. After connecting the wire but there is no display in screen.

Try reflashing
Clear as mud with all those wires and not knowing if the RX is needed or not and what setting ..
If even this does not work try reflashing using usbasp cable with latest firmware.
Bhai wo kaise hoga

Thanks man, he's method didn't work but yours did!

What if we change the controller? Will the new controller work? Or it’s a problem in something else...?
The problem is with the screen, change the screen instead
You saved my life dude
After we flash should we connect the esc back to where we had connected it before flashing
Yes
Thanks for the suggestions,
but while i incenses the THR, only the fourth motor is rotation, others are only making a beep sound..
my question is, can u suggest some that, that with this process, i could easily achieve the success for rotating all the four motors, in order to process the quad-copter operations.

Bro write your query here I'm active
Try reflashing the kk2. 1.5 board that may help
Ya planning on buying USBASP cable for that. But I don’t think that will work.
Do you sell flight controller. Maybe get a cheaper rate from you if you’re from INDIA
not working
Try reflashing the board
when i power on my transmitter, my board screen automatically blank
Then in that that case there is no problem with the board. Check if this thing happens with another transmitter. I think that there's some problem with the transmitter
