Hello, i have bricked my Flywoo GOKU Versatil F405 12v AIO By flashing "repartitionner", i know there is a big warning on the github, but i didn't go from github so was not inform about that... Well i made my mistake, lesson learned.

Question is, is tehre a way to unbricked the RX integrated in the AIO (it's UART1).
ELRS green led is i think fixed 100% of the time when quad is usb powered. I was not able to make it move, only thing i succeded moving is the FC led.

I tried to hold elrs button when i plug in the quad, didn't do much.
I tried passethrough flash, didn't worked

Every time i try something i have the log i joined.
======== RESET TO BOOTLOADER ========

  • Using full duplex (CRSF)
    Cannot detect RX target, blindly flashing!

What i get from that is that it doesn't recognize the RX ELRS.

I have read about FTDI tools to unbrick but don't understand how i can use it on an AIO.

Thanks for yout help.

it has a boot button for the receiver marked

#

RX-BOOT

#

hold that while powering on and try again

Ty for your help, I have tried that around 20 times, yet Rx still isn't seen

#

Is it possible button is broken? I feel the click but well... Maybe I can shortcut by wiring one side of the button to the other?

Don t be I appreciate the help

#

one thing you could try is disabling telemetry in betaflight, that can apparently sometimes interfere

I mean I have tried with and without

Did not worked

argh

Hehe

#

those would make sense to me to be the receiver rx and tx, based on their position and labelling but I can't be 100% sure , so you could try connecting an ftdi straight to that

otherwise nothing really comes to mind

Haha I did look at the board 200 times. First time I see this pins. Yeah should be it's what about 5v and ground? Should I wore the ftdi to the VCC and find from the board? I did send an email to fly woo for more info on procedure

#

I'd wire the ground to ground on the fc to have a common ground for the signal and leave the 5v out and power the fc using usb or whatever

Ok I need an ftdi tool now.

#

XD

i can't believe it the fucking pads came lose

#

can't solder thos pads to the ftdi...

tepid blaze
#

And for whatever reason now only the reciever get current. Well...

I think with these AIO boards you hold the button down, plug in the USB, go to BF config and it should show "DFU bootloader", click update firmware, then down the bottom click "Exit DFU Mode", then exit BF configurator. Now you should be able to flash via configurator using BF passthrough.

#

tried that didn't worked

#

and as the pads felt off dunno what happened but now only reciever is powered, so i guess i fucked a 100$ board 🙂
