FIX YOUR BRICKED SPRACING F3 BOARDS-Programming failed | No Response From Bootloader | Flashing

Easy way to fix "failed to connect to serial port" , "programming failed, no response from bootloader", solid blue light, and most other problems. Use the same process for the naze, but don't
change baud rate and download firmware for naze.

Steps:

-disconnect board
-short bootloader pins
-open up stm flasher
-set baudrate to 256000
-download firmware hex file
-flash
-un-short boot pins

You sir have just got me out of a 7 hour headache, I was supposed to be flying for my birthday tomorrow and I had bricked this fc today so thought I was screwed. Now I can relax and have a good birthday. Thank you so so much! Legend!

I cannot express how amazing this video is. I have SCOUERED the internet and decade old forums to figure out how to fix a single issue with this board. You solved all of them in 7 minutes. Thank you.

3 years later you still got to aid someones there. Thank you so much bud!

You are the man, man! I accidentally bricked my DYS Elf trying to update it to the wrong firmware. Not only have you helped me fix my microkwad, but now I also have D-shot commands available and can flip it back over after crashing upside down!

When I liked the video it got 1k likes . But Huge thanks to you man .
It's because of you after hours of struggle i could finally flash my board. Thanks a ton man. Just love your effort.

Thank you so This is the only tutorial that works since a week I was trying all the ways to get back my FC

[thomassmithers]

Took me 2 hours of trying to find out what to do and nothing worked. Then I found your video and it worked

Woke up this morning happy as I remembered how to re-flash my boards using the correct pins; thanks again. Subscribed.

Thank you much. I havent even gotten my drone off the ground before i had loaded the wrong software by accident. You are a lifesaver.

Excellent, just one little stumbling block, before you select your hex file, open the drop down box on the right and enable 'Hex' else it won't recognise the file type. Default seems to be 'en'. Worked brilliantly with two bricked boards. Thanks.

Love ya !!!
Trying all but nothing work . Your méthod work perfectly before I'm crying !

Gonna go to sleep with smile now 😁👌

[PaulDoodes]

OMG I've been trying for ages to connect the boot pins... and I was shorting the two pads near the word boot, not the two holes at the end of the rail.... thank you.

4 years later still working like a charm thanks for the post!

i think i had flashed the wrong firmware (instead of spracingf3, i did stm32 f3 discovery) and ended up with ""programming failed, no response from bootloader" (i think so). and your video solved the problem. thanks and keep up the good work.

Worked perfectly! Saved me a good $30 in ordering a new flight controller - took me a while to save up for my wizzard 220 and I tried hooking it up to work with my turnigy 9x - that worked --- to an extent - fast forward another 5 months and I bought a flysky FS I6 so I could use the S-bus instead of trying to make it work with just manual hookups to each channel (never got the auxiliaries to work properly in the first place with my 9x...the adventure continues and I have yet to maiden the thing - been just fooling around with 1s quads - they're lots of fun) had to recalibrate the sticks because channel 1 on the FS I6 kept drifting to the left so I didn't want to risk it even ordered a new direction gimbal (useful as a spare anyways) the recalibration did work although it will probably still drift... somewhere along the way as I was trying to program the SPracing f3 board in the wizzard i think I disabled the UART1 which I think also disabled the USB connection and afterwards the board wouln't connect to betaflight... tried reflashing it in there - couldn't get a response from the bootloader -after I followed the instructions here it worked first time with the flashloader. Thanks for the help mate!

[fabriciomedeiros]

Thank you, my friend !! I was thinking my FC was dead, and this procedure saved my board !! I was about to smash it with a hammer... LOL !!!! Thanks again !!! Amazing tutorial !!!!

[gordonrelyea]

Thanks, Sohan! You seem to be the only one to know the correct drivers. It works!

[mikef]
